The state of weariness following a period of exertion, mental or physical, characterized by a decreased capacity for work and reduced efficiency to respond to stimuli.
A state arrived at through prolonged and strong contraction of a muscle. Studies in athletes during prolonged submaximal exercise have shown that muscle fatigue increases in almost direct proportion to the rate of muscle glycogen depletion. Muscle fatigue in short-term maximal exercise is associated with oxygen lack and an increased level of blood and muscle lactic acid, and an accompanying increase in hydrogen-ion concentration in the exercised muscle.
A syndrome characterized by persistent or recurrent fatigue, diffuse musculoskeletal pain, sleep disturbances, and subjective cognitive impairment of 6 months duration or longer. Symptoms are not caused by ongoing exertion; are not relieved by rest; and result in a substantial reduction of previous levels of occupational, educational, social, or personal activities. Minor alterations of immune, neuroendocrine, and autonomic function may be associated with this syndrome. There is also considerable overlap between this condition and FIBROMYALGIA. (From Semin Neurol 1998;18(2):237-42; Ann Intern Med 1994 Dec 15;121(12): 953-9)
A condition of low alertness or cognitive impairment, usually associated with prolonged mental activities or stress.
A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.

Levels within a diagnostic group which are established by various measurement criteria applied to the seriousness of a patient's disorder.
Predetermined sets of questions used to collect data - clinical data, social status, occupational group, etc. The term is often applied to a self-completed survey instrument.
Conditions characterized by disturbances of usual sleep patterns or behaviors. Sleep disorders may be divided into three major categories: DYSSOMNIAS (i.e. disorders characterized by insomnia or hypersomnia), PARASOMNIAS (abnormal sleep behaviors), and sleep disorders secondary to medical or psychiatric disorders. (From Thorpy, Sleep Disorders Medicine, 1994, p187)
A common nonarticular rheumatic syndrome characterized by myalgia and multiple points of focal muscle tenderness to palpation (trigger points). Muscle pain is typically aggravated by inactivity or exposure to cold. This condition is often associated with general symptoms, such as sleep disturbances, fatigue, stiffness, HEADACHES, and occasionally DEPRESSION. There is significant overlap between fibromyalgia and the chronic fatigue syndrome (FATIGUE SYNDROME, CHRONIC). Fibromyalgia may arise as a primary or secondary disease process. It is most frequent in females aged 20 to 50 years. (From Adams et al., Principles of Neurology, 6th ed, p1494-95)

The musculofibrous partition that separates the THORACIC CAVITY from the ABDOMINAL CAVITY. Contraction of the diaphragm increases the volume of the thoracic cavity aiding INHALATION.
The amount of force generated by MUSCLE CONTRACTION. Muscle strength can be measured during isometric, isotonic, or isokinetic contraction, either manually or using a device such as a MUSCLE STRENGTH DYNAMOMETER.
Expenditure of energy during PHYSICAL ACTIVITY. Intensity of exertion may be measured by rate of OXYGEN CONSUMPTION; HEAT produced, or HEART RATE. Perceived exertion, a psychological measure of exertion, is included.
A syndrome characterized by new neuromuscular symptoms that occur at least 15 years after clinical stability has been attained in patients with a prior history of symptomatic poliomyelitis. Clinical features include new muscular weakness and atrophy of the limbs, bulbar innervated musculature, and muscles of respiration, combined with excessive fatigue, joint pain, and reduced stamina.

An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur. (Adams et al., Principles of Neurology, 6th ed, p903)
The testing of materials and devices, especially those used for PROSTHESES AND IMPLANTS; SUTURES; TISSUE ADHESIVES; etc., for hardness, strength, durability, safety, efficacy, and biocompatibility.
Fractures due to the strain caused by repetitive exercise.

Disorders characterized by hypersomnolence during normal waking hours that may impair cognitive functioning. Subtypes include primary hypersomnia disorders (e.g., IDIOPATHIC HYPERSOMNOLENCE; NARCOLEPSY; and KLEINE-LEVIN SYNDROME) and secondary hypersomnia disorders where excessive somnolence can be attributed to a known cause (e.g., drug affect, MENTAL DISORDERS, and SLEEP APNEA SYNDROME). (From J Neurol Sci 1998 Jan 8;153(2):192-202; Thorpy, Principles and Practice of Sleep Medicine, 2nd ed, p320)

Perioperative growth hormone treatment and functional outcome after major abdominal surgery: a randomized, double-blind, controlled study. (1/2703)

OBJECTIVE: To evaluate short- and long-term effects of perioperative human growth hormone (hGH) treatment on physical performance and fatigue in younger patients undergoing a major abdominal operation in a normal postoperative regimen with oral nutrition. SUMMARY BACKGROUND DATA: Muscle wasting and functional impairment follow major abdominal surgery. METHODS: Twenty-four patients with ulcerative colitis undergoing ileoanal J-pouch surgery were randomized to hGH (12 IU/day) or placebo treatment from 2 days before to 7 days after surgery. Measurements were performed 2 days before and 10, 30, and 90 days after surgery. RESULTS: The total muscle strength of four limb muscle groups was reduced by 7.6% in the hGH group and by 17.1% in the placebo group at postoperative day 10 compared with baseline values. There was also a significant difference between treatment groups in total muscle strength at day 30, and at the 90-day follow-up total muscle strength was equal to baseline values in the hGH group, but still significantly 5.9% below in the placebo group. The work capacity decreased by approximately 20% at day 10 after surgery, with no significant difference between treatment groups. Both groups were equally fatigued at day 10 after surgery, but at day 30 and 90 the hGH patients were less fatigued than the placebo patients. During the treatment period, patients receiving hGH had reduced loss of limb lean tissue mass, and 3 months after surgery the hGH patients had regained more lean tissue mass than placebo patients. CONCLUSIONS: Perioperative hGH treatment of younger patients undergoing major abdominal surgery preserved limb lean tissue mass, increased postoperative muscular strength, and reduced long-term postoperative fatigue.  (+info)

Carbon disulphide absorption during xanthate reagent mixing in a gold mine concentrator. (2/2703)

A xanthate reagent mixer at a gold mine concentrator was exposed to carbon disulphide by extensive skin contamination with xanthate powder and solution during the reagent mixing process. Absorption of carbon disulphide was confirmed by the detection of urinary 2-thiothiazolidine-4-carboxylic acid (TTCA). Drager colorimetric tube testing during subsequent mixing recorded a maximum concentration of at least 60 ppm carbon disulphide. An illness consisting of predominantly gastrointestinal symptoms began 20 h after the exposure. Although this may have been due to carbon disulphide toxicity this is by no means certain. The need for engineering controls, impervious protective clothing and full-face respirators with particulate and organic vapour cartridges is discussed. This episode occurred at another mine site, unrelated to Mount Isa Mines Limited.  (+info)

The role of capsaicin-sensitive muscle afferents in fatigue-induced modulation of the monosynaptic reflex in the rat. (3/2703)

1. The role of group III and IV afferent fibres of the lateral gastrocnemious muscle (LG) in modulating the homonymous monosynaptic reflex was investigated during muscle fatigue in spinalized rats. 2. Muscle fatigue was induced by a series of increasing tetanic electrical stimuli (85 Hz, 600 ms) delivered to the LG muscle nerve. Series consisted of increasing train numbers from 1 to 60. 3. Potentials from the spinal cord LG motor pool and from the ventral root were recorded in response to proprioceptive afferent stimulation and analysed before and during tetanic muscle activations. Both the pre- and postsynaptic waves showed an initial enhancement and, after a '12-train' series, an increasing inhibition. 4. The enhancement of the responses to muscle fatiguing stimulation disappeared after L3-L6 dorsal root section, while a partial reflex inhibition was still present. Conversely, after section of the corresponding ventral root, there was only a reduction in the inhibitory effect. 5. The monosynaptic reflex was also studied in animals in which a large number of group III and IV muscle afferents were eliminated by injecting capsaicin (10 mM) into the LG muscle. As a result of capsaicin treatment, the fatigue-induced inhibition of the pre- and postsynaptic waves disappeared, while the response enhancement remained. 6. We concluded that the monosynaptic reflex inhibition, but not the enhancement, was mediated by those group III and IV muscle afferents that are sensitive to the toxic action of capsaicin. The afferents that are responsible for the response enhancement enter the spinal cord through the dorsal root, while those responsible for the inhibition enter the spinal cord through both the ventral and dorsal roots.  (+info)

Effect of working hours on cardiovascular-autonomic nervous functions in engineers in an electronics manufacturing company. (4/2703)

A field survey of 147 engineers (23-49 years) in an electronics manufacturing company was conducted to investigate the effect of working hours on cardiovascular-autonomic nervous functions (urinary catecholamines, heart rate variability and blood pressure). The subjects were divided into 3 groups by age: 23-29 (n = 49), 30-39 (n = 74) and 40-49 (n = 24) year groups. Subjects in each age group were further divided into shorter (SWH) and longer (LWH) working hour subgroups according to the median of weekly working hours. In the 30-39 year group, urinary noradrenaline in the afternoon for LWH was significantly lower than that for SWH and a similar tendency was found in the LF/HF ratio of heart rate variability at rest. Because these two autonomic nervous indices are related to sympathetic nervous activity, the findings suggested that sympathetic nervous activity for LWH was lower than that for SWH in the 30-39 year group. Furthermore, there were significant relationships both between long working hours and short sleeping hours, and between short sleeping hours and high complaint rates of "drowsiness and dullness" in the morning in this age group. Summarizing these results, it appeared that long working hours might lower sympathetic nervous activity due to chronic sleep deprivation.  (+info)

Investigating fatigue of less than 6 months' duration. Guidelines for family physicians. (5/2703)

OBJECTIVE: To develop an evidence-based systematic approach to assessment of adult patients who present to family physicians complaining of fatigue of less than 6 months' duration. The guidelines present investigative options, making explicit what should be considered in all cases and what should be considered only in specific situations. They aim to provide physicians with an approach that, to the extent possible, is based on evidence so that time and cost are minimized and detection and management of the cause of the fatigue are optimized. QUALITY OF EVIDENCE: MEDLINE was searched from 1966 to 1997 using the key words "family practice" and "fatigue." Articles about chronic fatigue syndrome were excluded. Articles with level 3 evidence were found, but no randomized trials, cohort studies, or case-control studies were found. Articles looking specifically at the epidemiology, demographics, investigations, and diagnoses of patients with fatigue were chosen. Articles based on studies at referral and specialty centres were given less weight than those based on studies in family physicians' offices. MAIN MESSAGE: Adherence to these guidelines will decrease the cost of investigating the symptom of fatigue and optimize diagnosis and management. This needs to be proved in practice, however, and with research that produces level 1 and 2 evidence. CONCLUSIONS: Adults presenting with fatigue of less than 6 months' duration should be assessed for psychosocial causes and should have a focused history and physical examination to determine whether further investigations should be done. The guidelines outline investigations to be considered. The elderly require special consideration. These guidelines have group validation, but they need to be tested by more physicians in various locations and types of practices.  (+info)

Phase I and pharmacologic study of the combination of paclitaxel, cisplatin, and topotecan administered intravenously every 21 days as first-line therapy in patients with advanced ovarian cancer. (6/2703)

PURPOSE: To evaluate the feasibility of administering topotecan in combination with paclitaxel and cisplatin without and with granulocyte colony-stimulating factor (G-CSF) support as first-line chemotherapy in women with incompletely resected stage III and stage IV ovarian carcinoma. PATIENTS AND METHODS: Starting doses were paclitaxel 110 mg/m2 administered over 24 hours (day 1), followed by cisplatin 50 mg/m2 over 3 hours (day 2) and topotecan 0.3 mg/m2/d over 30 minutes for 5 consecutive days (days 2 to 6). Treatment was repeated every 3 weeks. After encountering dose-limiting toxicities (DLTs) without G-CSF support, the maximum-tolerated dose was defined as 5 microg/kg of G-CSF subcutaneously starting on day 6. RESULTS: Twenty-one patients received a total of 116 courses at four different dose levels. The DLT was neutropenia. At the first dose level, all six patients experienced grade 4 myelosuppression. G-CSF support permitted further dose escalation of cisplatin and topotecan. Nonhematologic toxicities, primarily fatigue, nausea/vomiting, and neurosensory neuropathy, were observed but were generally mild. Of 15 patients assessable for response, nine had a complete response, four achieved a partial response, and two had stable disease. CONCLUSION: Neutropenia was the DLT of this combination of paclitaxel, cisplatin, and topotecan. The recommended phase II dose is paclitaxel 110 mg/m2 (day 1), followed by cisplatin 75 mg/m2 (day 2) and topotecan 0.3 mg/m2/d (days 2 to 6) with G-CSF support repeated every 3 weeks.  (+info)

Manganese sulfate-dependent glycosylation of endogenous glycoproteins in human skeletal muscle is catalyzed by a nonglucose 6-P-dependent glycogen synthase and not glycogenin. (7/2703)

Glycogenin, a Mn2+-dependent, self-glucosylating protein, is considered to catalyze the initial glucosyl transfer steps in glycogen biogenesis. To study the physiologic significance of this enzyme, measurements of glycogenin mediated glucose transfer to endogenous trichloroacetic acid precipitable material (protein-bound glycogen, i.e., glycoproteins) in human skeletal muscle were attempted. Although glycogenin protein was detected in muscle extracts, activity was not, even after exercise that resulted in marked glycogen depletion. Instead, a MnSO4-dependent glucose transfer to glycoproteins, inhibited by glycogen and UDP-pyridoxal (which do not affect glycogenin), and unaffected by CDP (a potent inhibitor of glycogenin), was consistently detected. MnSO4-dependent activity increased in concert with glycogen synthase fractional activity after prolonged exercise, and the MnSO4-dependent enzyme stimulated glucosylation of glycoproteins with molecular masses lower than those glucosylated by glucose 6-P-dependent glycogen synthase. Addition of purified glucose 6-P-dependent glycogen synthase to the muscle extract did not affect MnSO4-dependent glucose transfer, whereas glycogen synthase antibody completely abolished MnSO4-dependent activity. It is concluded that: (1) MnSO4-dependent glucose transfer to glycoproteins is catalyzed by a nonglucose 6-P-dependent form of glycogen synthase; (2) MnSO4-dependent glycogen synthase has a greater affinity for low molecular mass glycoproteins and may thus play a more important role than glucose 6-P-dependent glycogen synthase in the initial stages of glycogen biogenesis; and (3) glycogenin is generally inactive in human muscle in vivo.  (+info)

Fatigue in advanced cancer: a prospective controlled cross-sectional study. (8/2703)

Uncontrolled studies have reported that fatigue is a common symptom among patients with advanced cancer. It is also a frequent complaint among the general population. Simply asking cancer patients whether or not they feel fatigued does not distinguish between the 'background' level of this symptom in the community and any 'excess' arising as a result of illness. The aim of this study was to determine the prevalence of fatigue among palliative care inpatients in comparison with a control group of age and sex-matched volunteers without cancer. In addition, the correlates of fatigue were investigated. The prevalence of 'severe subjective fatigue' (defined as fatigue greater than that experienced by 95% of the control group) was found to be 75%. Patients were malnourished, had diminished muscle function and were suffering from a number of physical and mental symptoms. The severity of fatigue was unrelated to age, sex, diagnosis, presence or site of metastases, anaemia, dose of opioid or steroid, any of the haematological or biochemical indices (except urea), nutritional status, voluntary muscle function, or mood. A multivariate analysis found that fatigue severity was significantly associated with pain and dypnoea scores in the patients, and with the symptoms of anxiety and depression in the controls. The authors conclude that subjective fatigue is both prevalent and severe among patients with advanced cancer. The causes of this symptom remain obscure. Further work is required in order to determine if the associations reported between fatigue and pain and between fatigue and dyspnoea are causal or coincidental.  (+info)

Fatigue is a state of feeling very tired, weary, or exhausted, which can be physical, mental, or both. It is a common symptom that can be caused by various factors, including lack of sleep, poor nutrition, stress, medical conditions (such as anemia, diabetes, heart disease, or cancer), medications, and substance abuse. Fatigue can also be a symptom of depression or other mental health disorders. In medical terms, fatigue is often described as a subjective feeling of tiredness that is not proportional to recent activity levels and interferes with usual functioning. It is important to consult a healthcare professional if experiencing persistent or severe fatigue to determine the underlying cause and develop an appropriate treatment plan.

Muscle fatigue is a condition characterized by a reduction in the ability of a muscle to generate force or power, typically after prolonged or strenuous exercise. It is often accompanied by sensations of tiredness, weakness, and discomfort in the affected muscle(s). The underlying mechanisms of muscle fatigue are complex and involve both peripheral factors (such as changes in muscle metabolism, ion handling, and neuromuscular transmission) and central factors (such as changes in the nervous system's ability to activate muscles). Muscle fatigue can also occur as a result of various medical conditions or medications that impair muscle function.

Chronic Fatigue Syndrome (CFS) is a complex disorder characterized by extreme fatigue that does not improve with rest and is often worsened by physical or mental activity. The exact cause of CFS remains unknown, although it can be triggered by various factors such as infections, immune system dysfunction, hormonal imbalances, and stress.

The main symptom of CFS is severe fatigue that lasts for six months or longer, which is not relieved by rest and is often accompanied by other symptoms such as:

* Difficulty concentrating or remembering things
* Sore throat
* Swollen lymph nodes in the neck or armpits
* Muscle pain
* Joint pain without redness or swelling
* Headaches of a new type, pattern, or severity
* Unrefreshing sleep
* Extreme exhaustion lasting more than 24 hours after physical or mental exercise

The diagnosis of CFS is based on the patient's symptoms and medical history, as there are no specific diagnostic tests for this condition. Treatment typically focuses on relieving symptoms and improving function through a combination of medications, lifestyle changes, and complementary therapies.

Mental fatigue is not a formally defined medical condition, but it's often used to describe the feeling of being mentally drained or exhausted due to prolonged periods of mental activity or stress. It can be characterized by symptoms such as difficulty concentrating, memory problems, mood changes, and reduced motivation or energy.

While mental fatigue is not a diagnosable medical condition, it can be a symptom of various underlying issues, including sleep disorders, mood disorders, neurological conditions, or other medical problems. If someone is experiencing significant mental fatigue that interferes with their daily functioning, they should consult a healthcare professional for further evaluation and treatment.

Muscle contraction is the physiological process in which muscle fibers shorten and generate force, leading to movement or stability of a body part. This process involves the sliding filament theory where thick and thin filaments within the sarcomeres (the functional units of muscles) slide past each other, facilitated by the interaction between myosin heads and actin filaments. The energy required for this action is provided by the hydrolysis of adenosine triphosphate (ATP). Muscle contractions can be voluntary or involuntary, and they play a crucial role in various bodily functions such as locomotion, circulation, respiration, and posture maintenance.

Skeletal muscle, also known as striated or voluntary muscle, is a type of muscle that is attached to bones by tendons or aponeuroses and functions to produce movements and support the posture of the body. It is composed of long, multinucleated fibers that are arranged in parallel bundles and are characterized by alternating light and dark bands, giving them a striped appearance under a microscope. Skeletal muscle is under voluntary control, meaning that it is consciously activated through signals from the nervous system. It is responsible for activities such as walking, running, jumping, and lifting objects.

Isometric contraction is a type of muscle activation where the muscle contracts without any change in the length of the muscle or movement at the joint. This occurs when the force generated by the muscle matches the external force opposing it, resulting in a balanced state with no visible movement. It is commonly experienced during activities such as holding a heavy object in static position or trying to push against an immovable object. Isometric contractions are important in maintaining posture and providing stability to joints.

Quality of Life (QOL) is a broad, multidimensional concept that usually includes an individual's physical health, psychological state, level of independence, social relationships, personal beliefs, and their relationship to salient features of their environment. It reflects the impact of disease and treatment on a patient's overall well-being and ability to function in daily life.

The World Health Organization (WHO) defines QOL as "an individual's perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns." It is a subjective concept, meaning it can vary greatly from person to person.

In healthcare, QOL is often used as an outcome measure in clinical trials and other research studies to assess the impact of interventions or treatments on overall patient well-being.

Physical endurance is the ability of an individual to withstand and resist physical fatigue over prolonged periods of strenuous activity, exercise, or exertion. It involves the efficient functioning of various body systems, including the cardiovascular system (heart, blood vessels, and blood), respiratory system (lungs and airways), and musculoskeletal system (muscles, bones, tendons, ligaments, and cartilage).

Physical endurance is often measured in terms of aerobic capacity or stamina, which refers to the body's ability to supply oxygen to muscles during sustained physical activity. It can be improved through regular exercise, such as running, swimming, cycling, or weightlifting, that challenges the body's major muscle groups and raises the heart rate for extended periods.

Factors that influence physical endurance include genetics, age, sex, fitness level, nutrition, hydration, sleep quality, stress management, and overall health status. It is essential to maintain good physical endurance to perform daily activities efficiently, reduce the risk of chronic diseases, and enhance overall well-being.

A Severity of Illness Index is a measurement tool used in healthcare to assess the severity of a patient's condition and the risk of mortality or other adverse outcomes. These indices typically take into account various physiological and clinical variables, such as vital signs, laboratory values, and co-morbidities, to generate a score that reflects the patient's overall illness severity.

Examples of Severity of Illness Indices include the Acute Physiology and Chronic Health Evaluation (APACHE) system, the Simplified Acute Physiology Score (SAPS), and the Mortality Probability Model (MPM). These indices are often used in critical care settings to guide clinical decision-making, inform prognosis, and compare outcomes across different patient populations.

It is important to note that while these indices can provide valuable information about a patient's condition, they should not be used as the sole basis for clinical decision-making. Rather, they should be considered in conjunction with other factors, such as the patient's overall clinical presentation, treatment preferences, and goals of care.

A questionnaire in the medical context is a standardized, systematic, and structured tool used to gather information from individuals regarding their symptoms, medical history, lifestyle, or other health-related factors. It typically consists of a series of written questions that can be either self-administered or administered by an interviewer. Questionnaires are widely used in various areas of healthcare, including clinical research, epidemiological studies, patient care, and health services evaluation to collect data that can inform diagnosis, treatment planning, and population health management. They provide a consistent and organized method for obtaining information from large groups or individual patients, helping to ensure accurate and comprehensive data collection while minimizing bias and variability in the information gathered.

Sleep disorders are a group of conditions that affect the ability to sleep well on a regular basis. They can include problems with falling asleep, staying asleep, or waking up too early in the morning. These disorders can be caused by various factors such as stress, anxiety, depression, medical conditions, or substance abuse.

The American Academy of Sleep Medicine (AASM) recognizes over 80 distinct sleep disorders, which are categorized into the following major groups:

1. Insomnia - difficulty falling asleep or staying asleep.
2. Sleep-related breathing disorders - abnormal breathing during sleep such as obstructive sleep apnea.
3. Central disorders of hypersomnolence - excessive daytime sleepiness, including narcolepsy.
4. Circadian rhythm sleep-wake disorders - disruption of the internal body clock that regulates the sleep-wake cycle.
5. Parasomnias - abnormal behaviors during sleep such as sleepwalking or night terrors.
6. Sleep-related movement disorders - repetitive movements during sleep such as restless legs syndrome.
7. Isolated symptoms and normal variants - brief and occasional symptoms that do not warrant a specific diagnosis.

Sleep disorders can have significant impacts on an individual's quality of life, productivity, and overall health. If you suspect that you may have a sleep disorder, it is recommended to consult with a healthcare professional or a sleep specialist for proper evaluation and treatment.

Fibromyalgia is a chronic disorder characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and cognitive difficulties. The pain typically occurs in specific tender points or trigger points, which are located on the neck, shoulders, back, hips, arms, and legs. These points are painful when pressure is applied.

The exact cause of fibromyalgia is unknown, but it appears to be related to abnormalities in the way the brain processes pain signals. It may also be associated with certain genetic factors, physical trauma, infection, or emotional stress. Fibromyalgia is more common in women than men and tends to develop between the ages of 20 and 50.

Fibromyalgia can be difficult to diagnose because its symptoms are similar to those of other conditions, such as rheumatoid arthritis, lupus, and chronic fatigue syndrome. However, a diagnosis of fibromyalgia may be made if a person has widespread pain for at least three months and tenderness in at least 11 of 18 specific points on the body when pressure is applied.

There is no cure for fibromyalgia, but medications, therapy, and lifestyle changes can help manage its symptoms. Treatment may include pain relievers, antidepressants, anti-seizure drugs, physical therapy, counseling, stress reduction techniques, and regular exercise.

Electromyography (EMG) is a medical diagnostic procedure that measures the electrical activity of skeletal muscles during contraction and at rest. It involves inserting a thin needle electrode into the muscle to record the electrical signals generated by the muscle fibers. These signals are then displayed on an oscilloscope and may be heard through a speaker.

EMG can help diagnose various neuromuscular disorders, such as muscle weakness, numbness, or pain, and can distinguish between muscle and nerve disorders. It is often used in conjunction with other diagnostic tests, such as nerve conduction studies, to provide a comprehensive evaluation of the nervous system.

EMG is typically performed by a neurologist or a physiatrist, and the procedure may cause some discomfort or pain, although this is usually minimal. The results of an EMG can help guide treatment decisions and monitor the progression of neuromuscular conditions over time.

Asthenopia is a medical term that refers to eye fatigue or discomfort, often accompanied by headache and blurred vision. It is typically caused by prolonged visual tasks such as reading, writing, or using a computer, especially in conditions of poor lighting or when focusing on a single object for a long time. Other factors that can contribute to asthenopia include uncorrected vision problems, eye strain, and dry eyes. Resting the eyes and addressing any underlying vision issues can help alleviate symptoms of asthenopia.

Depression is a mood disorder that is characterized by persistent feelings of sadness, hopelessness, and loss of interest in activities. It can also cause significant changes in sleep, appetite, energy level, concentration, and behavior. Depression can interfere with daily life and normal functioning, and it can increase the risk of suicide and other mental health disorders. The exact cause of depression is not known, but it is believed to be related to a combination of genetic, biological, environmental, and psychological factors. There are several types of depression, including major depressive disorder, persistent depressive disorder, postpartum depression, and seasonal affective disorder. Treatment for depression typically involves a combination of medication and psychotherapy.

Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. It is a complex phenomenon that can result from various stimuli, such as thermal, mechanical, or chemical irritation, and it can be acute or chronic. The perception of pain involves the activation of specialized nerve cells called nociceptors, which transmit signals to the brain via the spinal cord. These signals are then processed in different regions of the brain, leading to the conscious experience of pain. It's important to note that pain is a highly individual and subjective experience, and its perception can vary widely among individuals.

Neoplasms are abnormal growths of cells or tissues in the body that serve no physiological function. They can be benign (non-cancerous) or malignant (cancerous). Benign neoplasms are typically slow growing and do not spread to other parts of the body, while malignant neoplasms are aggressive, invasive, and can metastasize to distant sites.

Neoplasms occur when there is a dysregulation in the normal process of cell division and differentiation, leading to uncontrolled growth and accumulation of cells. This can result from genetic mutations or other factors such as viral infections, environmental exposures, or hormonal imbalances.

Neoplasms can develop in any organ or tissue of the body and can cause various symptoms depending on their size, location, and type. Treatment options for neoplasms include surgery, radiation therapy, chemotherapy, immunotherapy, and targeted therapy, among others.

"Torque" is not a term that has a specific medical definition. It is a physical concept used in the fields of physics and engineering, referring to a twisting force that causes rotation around an axis. However, in certain medical contexts, such as in discussions of spinal or joint biomechanics, the term "torque" may be used to describe a rotational force applied to a body part. But generally speaking, "torque" is not a term commonly used in medical terminology.

Treatment outcome is a term used to describe the result or effect of medical treatment on a patient's health status. It can be measured in various ways, such as through symptoms improvement, disease remission, reduced disability, improved quality of life, or survival rates. The treatment outcome helps healthcare providers evaluate the effectiveness of a particular treatment plan and make informed decisions about future care. It is also used in clinical research to compare the efficacy of different treatments and improve patient care.

Exercise is defined in the medical context as a physical activity that is planned, structured, and repetitive, with the primary aim of improving or maintaining one or more components of physical fitness. Components of physical fitness include cardiorespiratory endurance, muscular strength, muscular endurance, flexibility, and body composition. Exercise can be classified based on its intensity (light, moderate, or vigorous), duration (length of time), and frequency (number of times per week). Common types of exercise include aerobic exercises, such as walking, jogging, cycling, and swimming; resistance exercises, such as weightlifting; flexibility exercises, such as stretching; and balance exercises. Exercise has numerous health benefits, including reducing the risk of chronic diseases, improving mental health, and enhancing overall quality of life.

In the field of medicine, "time factors" refer to the duration of symptoms or time elapsed since the onset of a medical condition, which can have significant implications for diagnosis and treatment. Understanding time factors is crucial in determining the progression of a disease, evaluating the effectiveness of treatments, and making critical decisions regarding patient care.

For example, in stroke management, "time is brain," meaning that rapid intervention within a specific time frame (usually within 4.5 hours) is essential to administering tissue plasminogen activator (tPA), a clot-busting drug that can minimize brain damage and improve patient outcomes. Similarly, in trauma care, the "golden hour" concept emphasizes the importance of providing definitive care within the first 60 minutes after injury to increase survival rates and reduce morbidity.

Time factors also play a role in monitoring the progression of chronic conditions like diabetes or heart disease, where regular follow-ups and assessments help determine appropriate treatment adjustments and prevent complications. In infectious diseases, time factors are crucial for initiating antibiotic therapy and identifying potential outbreaks to control their spread.

Overall, "time factors" encompass the significance of recognizing and acting promptly in various medical scenarios to optimize patient outcomes and provide effective care.

A diaphragm is a thin, dome-shaped muscle that separates the chest cavity from the abdominal cavity. It plays a vital role in the process of breathing as it contracts and flattens to draw air into the lungs (inhalation) and relaxes and returns to its domed shape to expel air out of the lungs (exhalation).

In addition, a diaphragm is also a type of barrier method of birth control. It is a flexible dome-shaped device made of silicone that fits over the cervix inside the vagina. When used correctly and consistently, it prevents sperm from entering the uterus and fertilizing an egg, thereby preventing pregnancy.

Muscle strength, in a medical context, refers to the amount of force a muscle or group of muscles can produce during contraction. It is the maximum amount of force that a muscle can generate through its full range of motion and is often measured in units of force such as pounds or newtons. Muscle strength is an important component of physical function and mobility, and it can be assessed through various tests, including manual muscle testing, dynamometry, and isokinetic testing. Factors that can affect muscle strength include age, sex, body composition, injury, disease, and physical activity level.

Physical exertion is defined as the act of applying energy to physically demandable activities or tasks, which results in various body systems working together to produce movement and maintain homeostasis. It often leads to an increase in heart rate, respiratory rate, and body temperature, among other physiological responses. The level of physical exertion can vary based on the intensity, duration, and frequency of the activity.

It's important to note that engaging in regular physical exertion has numerous health benefits, such as improving cardiovascular fitness, strengthening muscles and bones, reducing stress, and preventing chronic diseases like obesity, diabetes, and heart disease. However, it is also crucial to balance physical exertion with adequate rest and recovery time to avoid overtraining or injury.

Post-poliomyelitis syndrome (PPS) is a condition that affects polio survivors years after recovery from the initial acute poliomyelitis infection. The symptoms of PPS include new onset weakness, fatigue, and pain in the muscles that were previously affected by the poliovirus. These symptoms can occur gradually or suddenly, and they may be worsened by exercise or other physical stressors.

PPS is thought to be caused by ongoing degeneration of the enlarged motor neurons that survived the initial polio infection. It is estimated that up to 50% of polio survivors may experience symptoms of PPS. While there is no cure for PPS, treatment typically focuses on managing symptoms and maintaining function through physical therapy, assistive devices, and pain management strategies.

Electric stimulation, also known as electrical nerve stimulation or neuromuscular electrical stimulation, is a therapeutic treatment that uses low-voltage electrical currents to stimulate nerves and muscles. It is often used to help manage pain, promote healing, and improve muscle strength and mobility. The electrical impulses can be delivered through electrodes placed on the skin or directly implanted into the body.

In a medical context, electric stimulation may be used for various purposes such as:

1. Pain management: Electric stimulation can help to block pain signals from reaching the brain and promote the release of endorphins, which are natural painkillers produced by the body.
2. Muscle rehabilitation: Electric stimulation can help to strengthen muscles that have become weak due to injury, illness, or surgery. It can also help to prevent muscle atrophy and improve range of motion.
3. Wound healing: Electric stimulation can promote tissue growth and help to speed up the healing process in wounds, ulcers, and other types of injuries.
4. Urinary incontinence: Electric stimulation can be used to strengthen the muscles that control urination and reduce symptoms of urinary incontinence.
5. Migraine prevention: Electric stimulation can be used as a preventive treatment for migraines by applying electrical impulses to specific nerves in the head and neck.

It is important to note that electric stimulation should only be administered under the guidance of a qualified healthcare professional, as improper use can cause harm or discomfort.

Neurasthenia is an outdated medical term that was once used to describe a condition characterized by physical and mental exhaustion, fatigue, anxiety, depression, and irritability. The diagnosis was commonly made during the late 19th and early 20th centuries. It was believed to be caused by exhaustion of the nervous system due to modern life's stresses and demands.

However, neurasthenia is not recognized as a distinct medical condition in modern psychiatry or neurology. The symptoms that were once attributed to neurasthenia are now more likely to be diagnosed as depression, anxiety disorders, chronic fatigue syndrome, or other conditions.

I'm sorry for any confusion, but "Work Schedule Tolerance" is not a recognized term in the medical field. It may be a term used in occupational health or human resources to refer to an employee's ability to adapt to different work schedules, such as night shifts, rotating shifts, or irregular hours. However, it is not a medical diagnosis or condition. If you have any concerns about your work schedule and how it affects your health, I would recommend speaking with a healthcare provider or occupational health professional.

In a medical context, "survivors" typically refers to individuals who have lived through or recovered from a serious illness, injury, or life-threatening event. This may include people who have survived cancer, heart disease, trauma, or other conditions that posed a significant risk to their health and well-being. The term is often used to describe the resilience and strength of these individuals, as well as to highlight the importance of ongoing support and care for those who have faced serious medical challenges. It's important to note that the definition may vary depending on the context in which it's used.

The Quadriceps muscle, also known as the Quadriceps Femoris, is a large muscle group located in the front of the thigh. It consists of four individual muscles - the Rectus Femoris, Vastus Lateralis, Vastus Intermedius, and Vastus Medialis. These muscles work together to extend the leg at the knee joint and flex the thigh at the hip joint. The Quadriceps muscle is crucial for activities such as walking, running, jumping, and kicking.

Sleep is a complex physiological process characterized by altered consciousness, relatively inhibited sensory activity, reduced voluntary muscle activity, and decreased interaction with the environment. It's typically associated with specific stages that can be identified through electroencephalography (EEG) patterns. These stages include rapid eye movement (REM) sleep, associated with dreaming, and non-rapid eye movement (NREM) sleep, which is further divided into three stages.

Sleep serves a variety of functions, including restoration and strengthening of the immune system, support for growth and development in children and adolescents, consolidation of memory, learning, and emotional regulation. The lack of sufficient sleep or poor quality sleep can lead to significant health problems, such as obesity, diabetes, cardiovascular disease, and even cognitive decline.

The American Academy of Sleep Medicine (AASM) defines sleep as "a period of daily recurring natural rest during which consciousness is suspended and metabolic processes are reduced." However, it's important to note that the exact mechanisms and purposes of sleep are still being researched and debated among scientists.

Multiple Sclerosis (MS) is a chronic autoimmune disease that affects the central nervous system (CNS), which includes the brain, spinal cord, and optic nerves. In MS, the immune system mistakenly attacks the protective covering of nerve fibers, called myelin, leading to damage and scarring (sclerosis). This results in disrupted communication between the brain and the rest of the body, causing a variety of neurological symptoms that can vary widely from person to person.

The term "multiple" refers to the numerous areas of scarring that occur throughout the CNS in this condition. The progression, severity, and specific symptoms of MS are unpredictable and may include vision problems, muscle weakness, numbness or tingling, difficulty with balance and coordination, cognitive impairment, and mood changes. There is currently no cure for MS, but various treatments can help manage symptoms, modify the course of the disease, and improve quality of life for those affected.

I'm happy to help! However, I must clarify that "materials testing" is not a medical term per se. It is a term used in various fields, including engineering and materials science, to describe the process of subjecting materials to different tests to evaluate their properties and performance under various conditions.

In the context of medical devices or implants, materials testing may refer to the evaluation of the physical and mechanical properties of materials used in their construction. These tests can include assessments of strength, durability, biocompatibility, and other factors that are critical to ensuring the safety and efficacy of medical devices.

Medical device manufacturers must comply with regulatory standards for materials testing to ensure that their products meet specific requirements for performance, safety, and quality. These standards may vary depending on the type of device, its intended use, and the country or region in which it will be marketed and sold.

Stress fractures are defined as small cracks or severe bruising in bones that occur from repetitive stress or overuse. They most commonly occur in weight-bearing bones, such as the legs and feet, but can also occur in the arms, hips, and back. Stress fractures differ from regular fractures because they typically do not result from a single, traumatic event. Instead, they are caused by repeated stress on the bone that results in microscopic damage over time. Athletes, military personnel, and individuals who engage in high-impact activities or have weak bones (osteoporosis) are at increased risk of developing stress fractures. Symptoms may include pain, swelling, tenderness, and difficulty walking or bearing weight on the affected bone.

Anxiety: A feeling of worry, nervousness, or unease, typically about an imminent event or something with an uncertain outcome. In a medical context, anxiety refers to a mental health disorder characterized by feelings of excessive and persistent worry, fear, or panic that interfere with daily activities. It can also be a symptom of other medical conditions, such as heart disease, diabetes, or substance abuse disorders. Anxiety disorders include generalized anxiety disorder, panic disorder, social anxiety disorder, and phobias.

In medical terms, the knee is referred to as the largest and one of the most complex joints in the human body. It is a hinge joint that connects the thigh bone (femur) to the shin bones (tibia and fibula), enabling movements like flexion, extension, and a small amount of rotation. The knee also contains several other components such as menisci, ligaments, tendons, and bursae, which provide stability, cushioning, and protection during movement.

Pain measurement, in a medical context, refers to the quantification or evaluation of the intensity and/or unpleasantness of a patient's subjective pain experience. This is typically accomplished through the use of standardized self-report measures such as numerical rating scales (NRS), visual analog scales (VAS), or categorical scales (mild, moderate, severe). In some cases, physiological measures like heart rate, blood pressure, and facial expressions may also be used to supplement self-reported pain ratings. The goal of pain measurement is to help healthcare providers better understand the nature and severity of a patient's pain in order to develop an effective treatment plan.

Exercise therapy is a type of medical treatment that uses physical movement and exercise to improve a patient's physical functioning, mobility, and overall health. It is often used as a component of rehabilitation programs for individuals who have experienced injuries, illnesses, or surgeries that have impaired their ability to move and function normally.

Exercise therapy may involve a range of activities, including stretching, strengthening, balance training, aerobic exercise, and functional training. The specific exercises used will depend on the individual's needs, goals, and medical condition.

The benefits of exercise therapy include:

* Improved strength and flexibility
* Increased endurance and stamina
* Enhanced balance and coordination
* Reduced pain and inflammation
* Improved cardiovascular health
* Increased range of motion and joint mobility
* Better overall physical functioning and quality of life.

Exercise therapy is typically prescribed and supervised by a healthcare professional, such as a physical therapist or exercise physiologist, who has experience working with individuals with similar medical conditions. The healthcare professional will create an individualized exercise program based on the patient's needs and goals, and will provide guidance and support to ensure that the exercises are performed safely and effectively.

A chronic disease is a long-term medical condition that often progresses slowly over a period of years and requires ongoing management and care. These diseases are typically not fully curable, but symptoms can be managed to improve quality of life. Common chronic diseases include heart disease, stroke, cancer, diabetes, arthritis, and COPD (chronic obstructive pulmonary disease). They are often associated with advanced age, although they can also affect children and younger adults. Chronic diseases can have significant impacts on individuals' physical, emotional, and social well-being, as well as on healthcare systems and society at large.

Disorders of excessive somnolence (DES) are a group of medical conditions characterized by an increased tendency to fall asleep or experience excessive daytime sleepiness (EDS), despite having adequate opportunity and circumstances for sleep. These disorders are typically classified as central disorders of hypersomnolence according to the International Classification of Sleep Disorders (ICSD-3).

The most common DES is narcolepsy, a chronic neurological disorder caused by the brain's inability to regulate sleep-wake cycles normally. Other DES include idiopathic hypersomnia, Kleine-Levin syndrome, and recurrent hypersomnia. These disorders can significantly impact an individual's daily functioning, quality of life, and overall health.

Narcolepsy is further divided into two types: narcolepsy type 1 (NT1) and narcolepsy type 2 (NT2). NT1 is characterized by the presence of cataplexy, a sudden loss of muscle tone triggered by strong emotions, while NT2 does not include cataplexy. Both types of narcolepsy involve excessive daytime sleepiness, sleep paralysis, hypnagogic/hypnopompic hallucinations, and fragmented nighttime sleep.

Idiopathic hypersomnia is a DES without the presence of REM-related symptoms like cataplexy or sleep paralysis. Individuals with idiopathic hypersomnia experience excessive daytime sleepiness and prolonged nighttime sleep, often lasting 10 to 14 hours, but do not feel refreshed upon waking.

Kleine-Levin syndrome is a rare DES characterized by recurrent episodes of excessive sleepiness, often accompanied by cognitive impairment, altered perception, hyperphagia (excessive eating), and hypersexuality during the episodes. These episodes can last days to weeks and typically occur multiple times per year.

Recurrent hypersomnia is another rare DES with recurring episodes of excessive sleepiness lasting for several days, followed by a period of normal or reduced sleepiness. The episodes are not as predictable or consistent as those seen in Kleine-Levin syndrome.

Treatment for DES typically involves pharmacological interventions to manage symptoms and improve daytime alertness. Modafinil, armodafinil, and traditional stimulants like amphetamine salts are commonly used to treat excessive daytime sleepiness. Additionally, antidepressants may be prescribed to manage REM-related symptoms like cataplexy or sleep paralysis. Non-pharmacological interventions, such as scheduled napping and good sleep hygiene practices, can also help improve symptoms.

Mechanical stress, in the context of physiology and medicine, refers to any type of force that is applied to body tissues or organs, which can cause deformation or displacement of those structures. Mechanical stress can be either external, such as forces exerted on the body during physical activity or trauma, or internal, such as the pressure changes that occur within blood vessels or other hollow organs.

Mechanical stress can have a variety of effects on the body, depending on the type, duration, and magnitude of the force applied. For example, prolonged exposure to mechanical stress can lead to tissue damage, inflammation, and chronic pain. Additionally, abnormal or excessive mechanical stress can contribute to the development of various musculoskeletal disorders, such as tendinitis, osteoarthritis, and herniated discs.

In order to mitigate the negative effects of mechanical stress, the body has a number of adaptive responses that help to distribute forces more evenly across tissues and maintain structural integrity. These responses include changes in muscle tone, joint positioning, and connective tissue stiffness, as well as the remodeling of bone and other tissues over time. However, when these adaptive mechanisms are overwhelmed or impaired, mechanical stress can become a significant factor in the development of various pathological conditions.

Activities of Daily Living (ADL) are routine self-care activities that individuals usually do every day without assistance. These activities are widely used as a measure to determine the functional status and independence of a person, particularly in the elderly or those with disabilities or chronic illnesses. The basic ADLs include:

1. Personal hygiene: Bathing, washing hands and face, brushing teeth, grooming, and using the toilet.
2. Dressing: Selecting appropriate clothes and dressing oneself.
3. Eating: Preparing and consuming food, either independently or with assistive devices.
4. Mobility: Moving in and out of bed, chairs, or wheelchairs, walking independently or using mobility aids.
5. Transferring: Moving from one place to another, such as getting in and out of a car, bath, or bed.

There are also more complex Instrumental Activities of Daily Living (IADLs) that assess an individual's ability to manage their own life and live independently. These include managing finances, shopping for groceries, using the telephone, taking medications as prescribed, preparing meals, and housekeeping tasks.

Exercise tolerance is a term used to describe the ability of an individual to perform physical activity or exercise without experiencing symptoms such as shortness of breath, chest pain, or undue fatigue. It is often used as a measure of cardiovascular fitness and can be assessed through various tests, such as a stress test or a six-minute walk test. Exercise intolerance may indicate the presence of underlying medical conditions, such as heart disease, lung disease, or deconditioning.

Biomechanics is the application of mechanical laws to living structures and systems, particularly in the field of medicine and healthcare. A biomechanical phenomenon refers to a observable event or occurrence that involves the interaction of biological tissues or systems with mechanical forces. These phenomena can be studied at various levels, from the molecular and cellular level to the tissue, organ, and whole-body level.

Examples of biomechanical phenomena include:

1. The way that bones and muscles work together to produce movement (known as joint kinematics).
2. The mechanical behavior of biological tissues such as bone, cartilage, tendons, and ligaments under various loads and stresses.
3. The response of cells and tissues to mechanical stimuli, such as the way that bone tissue adapts to changes in loading conditions (known as Wolff's law).
4. The biomechanics of injury and disease processes, such as the mechanisms of joint injury or the development of osteoarthritis.
5. The use of mechanical devices and interventions to treat medical conditions, such as orthopedic implants or assistive devices for mobility impairments.

Understanding biomechanical phenomena is essential for developing effective treatments and prevention strategies for a wide range of medical conditions, from musculoskeletal injuries to neurological disorders.

Analysis of Variance (ANOVA) is a statistical technique used to compare the means of two or more groups and determine whether there are any significant differences between them. It is a way to analyze the variance in a dataset to determine whether the variability between groups is greater than the variability within groups, which can indicate that the groups are significantly different from one another.

ANOVA is based on the concept of partitioning the total variance in a dataset into two components: variance due to differences between group means (also known as "between-group variance") and variance due to differences within each group (also known as "within-group variance"). By comparing these two sources of variance, ANOVA can help researchers determine whether any observed differences between groups are statistically significant, or whether they could have occurred by chance.

ANOVA is a widely used technique in many areas of research, including biology, psychology, engineering, and business. It is often used to compare the means of two or more experimental groups, such as a treatment group and a control group, to determine whether the treatment had a significant effect. ANOVA can also be used to compare the means of different populations or subgroups within a population, to identify any differences that may exist between them.
