The major finding of this study was 2-fold lower vestibular cold pain thresholds (cold pain reported at higher temperatures) in participants with PLV compared with control participants. To date, little attention has been paid to cold pain thresholds in this patient population despite numerous reports of decreased cold pain thresholds in QST studies of other types of chronic pain.16-21 A 2001 study reported qualitative differences in vestibular cold pain thresholds in patients with PLV compared with controls.8 Subsequent QST studies of patients with PLV did not include vestibular pain thresholds to cold stimuli in the QST protocol.5-7,9,10 In the study by Bohm-Starke et al,8 the majority of participants did not report cold pain in the posterior vestibule within the range of testing temperatures (31°C-6°C), which limited the ability to identify differences in cold pain thresholds. We therefore used a testing range of 32°C to 0°C, and 2 control participants did not report pain at 0°C. Our ...
PMID: 22558610 Aims: To investigate the influence of noxious stimulation of the temporomandibular joint (TMJ) on conditioned pain modulation (CPM) and the possible influence of gender on such CPM effects in the craniofacial region of humans. Methods: Twenty healthy men and 20 healthy women participated in two sessions. Conditioning stimulation (CS) was standardized mechanical stimulation of pericranial muscles at a pain level of 5 on a 0 to 10 visual analog scale (VAS). Intra-articular electrical stimuli were applied to the left TMJ with an intensity around VAS = 5 (painful session). No electrical stimulation was applied in the control session. Pressure pain threshold (PPT) and pressure pain tolerance threshold (PPTol) were used as responses to pressure (test) stimuli and were assessed in the right masseter muscle and left forearm before and during TMJ stimulation in addition to the CS (during, immediately after, and 10 minutes after CS). PPT and PPTol were analyzed by multilevel analysis of ...

Objectives: A tool for measuring neck pain in patients with dizziness is needed to further investigate the relationship between the two symptoms. The objective of this study was to examine the reliability and validity of a hand‐held pressure algometer in measuring pressure pain threshold (PPT) in different cervical regions of dizzy patients. Methods: PPT was measured at two bilateral standardized sites of the neck by a trained physiotherapist in 50 patients with dizziness. Intraclass correlation coefficients (ICC) were calculated for intrarater and test-retest reliability. Concurrent validity was assessed by measuring the association between PPT and the American College of Rheumatology (ACR) tender points at each site and with the numeric pain rating scale (NPRS). Results: Almost perfect intrarater (ICC = 0.815-0.940) and within‐session test-retest (ICC = 0.854-0.906) reliability was found between the measures. On each site, a low PPT predicted a positive ACR tender point at each site (OR = ...
Assessing the responses of body tissue subjected to mechanical load is a fundamental component of the clinical examination, psychophysical assessments and bioengineering research. The forces applied during such assessments are usually generated manually, via the hands of the tester, and aimed at discreet tissue sites. It is therefore desirable to objectively quantify and optimise the control of manually applied force. However, current laboratory-grade manual devices and commercial software packages, in particular pressure algometer systems, are generally inflexible and expensive. This paper introduces and discusses several principles that should be implemented as design goals within a flexible, generic software application, given currently available force measurement hardware. We also discuss pitfalls that clinicians and researchers might face when using current pressure algometer systems and provide examples of these. Finally, we present our implementation of a pressure algometer system that achieves
Spexin is a central modulator of nociception. The aim of the present study was to investigate the effect of intra-hippocampal CA3 (IHCA3) injection of spexin and spexin-progesterone co-administration on pain sensitivity in ovariectomized rat. Thirty-five adult female rats were divided into five groups. Sham: the animals received injection of 0.5 μL ACSF by IHCA3. Experiments 1 and 2: the animals received injection of 0.5 μL of spexin bilaterally (10 and 30 nmol/rat respectively). Experiments 3 and 4: the animals received injection of 0.5 μL of spexin bilaterally (10 and 30 nmol/rat respectively) + subcutaneous (s.c.) injection of progesterone (5 mg/kg). Ovariectomy was performed in all groups to eliminate the effects of cyclic changes in the female rats. The formalin test (formalin 2.5%) was performed following the administration of spexin and progesterone. Results showed that bilateral injection of spexin in IHCA3 at both concentrations a significant (P < .05) decrease in the pain ...
A decrease in mechanical pressure pain thresholds,particularly over pre-designated tender points, is one of thedefining characteristics of f
Accumulating evidence points to sex differences in pain sensitivity and many chronic pain conditions preferentially affect women. Sex hormones, and in particular estrogens, have been shown to affect pain processing and pain sensitivity in animals, although the findings are divergent. The aim of the research on which this thesis is based was to examine the effect of gonadal hormones on the sensation of pain in women who either presented normal variations in hormonal levels over time or who had been given hormone treatment.. Different quantitative sensory tests (QST) examining temperature thresholds, cold, heat and pressure pain thresholds, as well as tolerance thresholds for heat and cold, were performed during different hormonal conditions: During hormonal fluctuations throughout the ovulatory cycle (papers I, II); in women undergoing in vitro fertilization (IVF), a treatment associated with extremely low and high 17β-estradiol levels (paper III); and before and after hormonal substitution ...
Musculoskeletal pain in the low back and neck-shoulder regions is a major problem among the working population all over the world. The prevalence of musculoskeletal pain is found to be higher among women. Women also have lower pressure pain thresholds (PPTs) than men. Pressure pain topography aims at mapping the spatial distribution of PPT within a muscle in an attempt to track changes in mechanical sensitivity. In order to assess gender differences in the pain topography, it is necessary to map the distribution in both healthy men and women. The aim of this study was to assess PPT maps from the cervico-thoracic and lumbar regions in men and women. Eleven men and eleven women without any known musculoskeletal disorders participated in the study. PPT was measured twice at 36 points over the trapezius muscle of the dominant arm, at 36 points over the trapezius muscle on the contralateral side and at 12 points over the spine between the left and right trapezius. Further, 11 points were measured over the
Triathletes and ironman triathletes participate in an extremely intense sport that involves hours of considerable pain, in addition to physical and psychological stress, every day. The basic pain modulation properties of these athletes has not been established and for this reason it is not clear whether they present with unique features that make it possible for them to engage in such efforts. This studys goal was to investigate the existence of possible alterations in pain perception and modulation of triathletes, in addition to possible underlying factors. 19 triathletes and 17 non-athletes who underwent measurement of pain threshold, pain tolerance, suprathreshold perceived pain intensity, temporal summation of pain, and conditioned pain modulation (CPM) participated in the study. Participants also completed the fear of pain and the pain catastrophizing questionnaires, and rated the amount of perceived stress. Triathletes exhibited higher pain tolerance (P,.0001), lower pain ratings ...
In this study, we investigated whether an abnormal hypothalamic-pituitary-adrenal (HPA) axis response to psychosocial stress at 18 years of age is associated with musculoskeletal (MS) pain alone and MS pain combined with increased pain sensitivity at 22 years of age. The study sample included 805 participants from the Western Australian Pregnancy Cohort (Raine) Study who participated in the Trier Social Stress Test (TSST) at age 18 years. Number of pain sites, pain duration, pain intensity and pain frequency were assessed at age 22 to measure severity of MS pain. Cold and pressure pain thresholds were determined at age 22. Group-based trajectory modeling was applied to establish cortisol response patterns based on the TSST. Logistic regression was used to study the association of TSST patterns with MS pain alone and MS pain combined with increased cold or pressure pain sensitivity, adjusted for relevant confounding factors. All analyses were stratified by sex. The mean (standard deviation) age during

Pain threshold: Wheres yours?. Is it too low?. Once the pain starts, do you crumble? Maybe slow down, start to feel sorry for yourself. This hurts. Its soooo hard.. Is it too high?. When the pain starts, do you kind of dig it? Like, Yeah, this is what I came here for? Do you start to look forward to pain, like a high? And you find yourself lingering there, past the point of any good and well into doing real damage, because the hurt feels so damn good. You dont want to leave it.. If youre in either of those categories, get the hell out of them.. Really, theyre not healthy.. Pain is just pain: an unpleasant but necessary part of life.. You go into it and you come back out of it. Learn to accept the pain condition but dont avoid it and dont linger in it.. So many problems in our lives are caused by avoidance of pain or by staying too long in pain.. Find your pain threshold and learn to deal with it, to perform while youre standing on that threshold - in fitness and in life. Then come ...
Chronic widespread pain and fibromyalgia often coexist with temporomandibular disorders (TMD) and affects mostly women. Studies have shown lower pressure pain thresholds (PPT) in these patients indicating that hyperalgesia is involved. The aim for this study was to investigate the effect of topical anesthesia on PPT for jaw muscles in patients with widespread pain. The hypothesis was that the PPT in these patients would increase after applying topical anesthetic cream. Ten women (aged 25-64 years, median: 50 years) diagnosed with TMD associated with widespread pain, reported from at least three different anatomical sites apart from the jaw region and pain to palpation according to the American College of Rheumatology criteria 1990, were included in the study. The double blind randomized trial was based on measurements of PPT with an Algometer before and after the application of anesthetic cream (EMLA) or placebo cream. The chosen measurement sites were the anterior part of the temporal muscle ...
Pain sensitivity may determine the risk, severity, prognosis, and efficacy of treatment of clinical pain. Magnetic resonance imaging studies have linked thermal pain sensitivity to changes in brain structure. However, the neural correlates of mechanical pain sensitivity remain to be clarified through investigation of direct neural activities on the resting-state cortical oscillation and synchrony. We recorded the resting-state magnetoencephalographic (MEG) activities of 27 healthy individuals and 30 patients with episodic migraine (EM) and analyzed the source-based oscillatory powers and functional connectivity at 2 to 59 Hz in pain-related cortical regions, which are the bilateral anterior cingulate cortex (ACC), medial orbitofrontal (MOF) cortex, lateral orbitofrontal (LOF) cortex, insula cortex, primary somatosensory cortex (SI), primary motor cortex (MI), and posterior cingulate cortex (PCC). The mechanical punctate pain threshold (MPPT) was obtained at the supraorbital area (the first branch of the
RESULTS: Thermal pain threshold latency was longer in BN than in HW in all six conditions. It increased during mental arithmetic test and remained increased during the rest of the experiment in both groups. In the BN group, the increase of pain threshold during mental arithmetic was positively correlated with illness duration. The differential modulation of pain threshold by stress in BN and HW could not be explained by autonomic system reactivity. In HW, the pain threshold increased more during eating and blood pressure increased more during mental stress; in BN, the pain threshold was highest in the mental stress condition and blood pressure was most increased during eating. During the cold pressor test, women with BN showed smaller blood pressure increase and tolerated the cold for shorter time than HW ...
Materials and Methods: In this study, a total of 100 medical students (male 57 and female 43) were participated. The cold pressor test was used to give pain as noxious stimuli. Respiratory parameters (respiratory rate and vital capacity) and pain sensitivity parameters (pain rating using visual analog scale, pain tolerance, and pain threshold) were measured. Results: Respiratory reactivity in response to experimental pain applied by cold pressor test in both sexes was not found significant in this study. Second, we found no remarkable correlation between respiratory system and pain sensitivity in both sexes ...
From a methodologic viewpoint, it is difficult in clinical trials to differentiate short-term tolerance from an exaggerated postoperative pain, both of them requiring exaggerated morphine consumption for their relief. Conversely, in the absence of verbal reports in animals, classic measurements of nociceptive thresholds as used in most of the experimental studies allowed assessment of only a pain sensitivity level, not a spontaneous pain level, in the absence of experimental nociceptive stimuli. Therefore, an enhancement in experimental pain sensitivity does not necessarily mean that there is spontaneous pain.29 In fact, a decrease in nociceptive threshold values in animals means only that there is an exaggerated vulnerability to nociceptive inputs. To address this difficulty, we used in rats a test enabling us to quantify spontaneous postural changes reflecting spontaneous pain by independently measuring the weight that the animal applies on each hind paw after a unilateral hind paw tissue ...

JSH-23 is a nuclear factor-kappa B (NF-κB) nuclear translocation inhibitor. JSH-23 inhibits LPS and cytokine-induced nuclear translocation of the p65 subunit of NF-kB as analyzed by EMSA and western blot. JSH-23 treatment significantly reversed the nerve conduction and nerve blood flow deficits seen in diabetic animals. Reduction in mechanical pain threshold was also partially corrected by the treatment. Protein expression studies showed that nuclear translocation of p65/p50 subunit was inhibited by JSH-23 treatment in the sciatic nerve..

What is clear is that [Castillo] sustained an injury far beyond what his body could tolerate, no matter how much degree of injury was delivered, he added.. Yolo said Castillo must have died a slow and painful death.. My tolerance of the degree of pain is different from others and may not necessarily reflect a scale similar to the degree of pain [that] Castillo experienced, he said.. Body tolerance is dependent on many factors such as age, physical stature, gender and conditions such as heart diseases, said Yolo.. Pain threshold is the minimum intensity at which a person begins to perceive, or sense, a stimulus as being painful. Pain tolerance, is the maximum amount, or level, of pain a person can tolerate or bear.. The threshold for pain can differ between men and women, and can uctuate based on many other factors.. Pain researchers believe regular exposure to painful stimuli can increase ones pain tolerance.. Some individuals learn to handle pain by becoming more conditioned to it, ...
Thermal stimuli will be administered to the ventral surface of the dominant forearm and then to the lower abdomen (surgical site)using the Thermal Sensory Analyser. Each thermal testing trial will be separated by approximately 2 min and at a separate site.. To measure the thermal pain threshold temperature, The thermode will be applied to the ventral surface of the dominant forearm and the temperature will be increased at 1°C/s from 35 to 50°C.. To measure the Suprathreshold Thermal Pain Intensity and unpleasantness, Stimulus responses for noxious heat stimuli will be performed by applying phasic heat stimuli at 8 different temperatures (35, 43, 44, 45, 46, 47, 48, and 49°C). ...
Neuropathic or idiopathic pain patients will be assessed with the variety of pain tests including the conditioned pain modulation (CPM) and temporal summation (TS). Then, they will be offered on the double-blind design a several weeks treatment with either pregabalin or duloxetine. Patients will be followed-up weekly by phone for their pain relief and will be re-assessed in the lab toward the end of the treatment. The investigators suggest that patients with less-efficient CPM (deficient pain inhibition) will earn more pain relief from the treatment with duloxetine, while the patients with the enhanced pain summation will response better to pregabalin ...
Background Unrecognized myocardial infarction (MI) is a prevalent condition associated with a similar risk of death as recognized MI. It is unknown why some persons experience MI with few or no symptoms; however, one possible explanation is attenuated pain sensitivity. To our knowledge, no previous study has examined the association between pain sensitivity and recognition of MI. Methods and Results We conducted a population‐based cross‐sectional study with 4849 included participants who underwent the cold pressor test (a common experimental pain assay) and ECG. Unrecognized MI was present in 387 (8%) and recognized MI in 227 (4.7%) participants. Participants with unrecognized MI endured the cold pressor test significantly longer than participants with recognized MI (hazard ratio for aborting the cold pressor test, 0.64; CI, 0.47-0.88), adjusted for age and sex. The association was attenuated and borderline significant after multivariable adjustment. The association between unrecognized MI ...

The pain relief effect of opioids is induced by the synergy of two events, namely the reduction of pain threshold and emotional detachment from pain.
Duragesic MAT: Fentanyl belongs to a group of medications called opioids. Fentanyl is used to treat persistent chronic (long-term) moderate-to-severe pain for those who need constant pain relief and are currently taking other opioid (narcotic) medications. It acts on the brain to increase pain tolerance.
No two people have the same pain threshold; your sister could be in agony after disc surgery, while you could pop an aspirin and feel fine. Physical therapy or even behavioral therapy, which teaches you cognitive techniques to modify pain triggers, can also play a part of your pain management. Ask before accepting the prescription.. If you decide that opioids are the right choice for you, ask to be prescribed only what you will need, dont assume a refill will be necessary. If your pain persists, follow up with your doctor to discuss your options.. Never take home more than you need and make sure you store them in a secure place, out of the reach of others. According to the US Department of Health and Human Services Substance Abuse and Mental Health Administration, 54% of young people using opioids report getting them from a friend or family.. And what do you do with leftovers? Dont keep them for the next time youre hurt or in pain, and never share them with others. Ask your pharmacist ...

If 5 ml syringes are employed, each rubber seal is 1.12 cm in diameter and therefore presents an area of 1 cm2.. To prevent air escaping from the syringe, push one of these rubber seals down the barrel of the syringe to its furthest extent. Reinsert an intact piston into this syringe. Air is now trapped in the barrel of the syringe between the two seals: the volume of air is progressively reduced by compression when the piston is pushed forcibly into the syringe.. A cable (zip) tie is used to form a loop around the external surface of the syringe cylinder. The geared surface of the tie is passed through its ratchet to form a loop around the syringe. Ensure the loop is tight enough to stay in one place when left alone but can still be slid manually up or down the cylinder when required. Remove excess tie material.. The base of the syringe piston is now pressed against a weighing scale to provide a given force of, for example, 1.5 kg.. While this force is being provided, the cable tie is slid over ...

The aim is to evaluate the influence of oral contraceptive intake and menstrual cycle on the electrical activity and pressure pain threshold from anterior temporal and masseter muscles. Twenty-eight women on reproductive age were selected, 13 OC users and 15 nonusers. They were weekly submitted to electromyography and algometry of the anterior temporal and masseter muscles during three consecutive menstrual cycles. Electrical activities at rest position and PPTs of temporal and masseter muscles were not affected by menstrual cycle or by OCs uses. Comparison between groups demonstrated that working side electrical activity was increased in OC users in both muscles, except during lutheal phase for the anterior temporal. However, comparison within weeks did not demonstrate statistical difference. It was suggested that, in healthy women, oral contraceptive use may influence electrical activity, but different phases of the cycle may not.. ...
This page contains the abstract Association Between Primary Dysmenorrhea and Pain Threshold at the Thoracolumbar Junction http://www.chiro.org/research/ABSTRACTS/Association_Between_Primary_Dysmenorrhea.shtml
Pain tolerance is the maximum level of pain that a person is able to tolerate. Pain tolerance is distinct from pain threshold (the point at which pain begins to be felt). The perception of pain that goes in to pain tolerance has two major components. First is the biological component-the headache or skin prickling that activates pain receptors. Second is the brains perception of pain-how much focus is spent paying attention to or ignoring the pain. The brains perception of pain is a response to signals from pain receptors that sensed the pain in the first place. Clinical studies by the journal of Psychosomatic Medicine found that men had higher pain thresholds and tolerances and lower pain ratings than women when they are exposed to cold pressor pain. The study asked participants to submerge their hands in ice water (the cold pressor pain procedure) and told members of the experimental group (as opposed to the control group) that they would be compensated financially for keeping their hand ...
BACKGROUND: Correlations between clinical and quantitative measures of pain sensitivity are poor, making it difficult for clinicians to detect people with pain sensitivity. Clinical detection of pain sensitivity is important because these people have a different prognosis and may require different treatment. OBJECTIVE: The purpose of this study was to investigate the relationship between clinical and quantitative measures of pain sensitivity across individuals with and without neck pain. METHODS: This cross-sectional study included 40 participants with chronic neck pain and 40 age- and sex-matched controls. Participants underwent quantitative sensory testing of cold pain thresholds (CPTs) and pressure pain thresholds (PPTs). Clinical tests for pain sensitivity were the ice pain test and the pressure pain test. All tests were undertaken at standardized local (neck and upper trapezius muscles) and remote (wrist and tibialis anterior muscles) sites. Median and interquartile range (IQR) were ...
Background: Roller massage (RM) has become a common intervention among health and fitness professionals. Recently, manufacturers have merged the science of vibration therapy and RM with the development of vibration rollers. Of interest, is the therapeutic effects of such RM devices. Purpose: The purpose of this study was to compare the effects of a vibration roller and nonvibration roller intervention on prone knee-flexion passive range of motion (ROM) and pressure pain threshold (PPT) of the quadriceps musculature. Methods: Forty-five recreationally active adults were randomly allocated to one of 3 groups: vibration roller, nonvibration roller, and control. Each roller intervention lasted a total of 2 minutes. The control group did not roll. Dependent variables included prone knee-flexion ROM and PPT measures. Statistical analysis included parametric and nonparametric tests to measure changes among groups. Results: The vibration roller demonstrated the greatest increase in PPT (180 kPa, P , ...
Patellofemoral Pain (PFP) is highly prevalent among adults and adolescents. Localized mechanical hyperalgesia around the knee and tibialis anterior have been observed in people with PFP, but limited knowledge of potential manifestations of central sensitisation exists. The aims of this study were to study conditioned pain modulation (CPM) and wide-spread hyperalgesia in adults with PFP. This assessor-blinded cross-sectional study design compared CPM and mechanical pressure pain thresholds (PPT) between 33 adults (23 females) diagnosed with PFP and 32 age and sex matched pain-free controls. The investigator taking the PPT measurements was blinded to which participants had PFP. PPTs were reliably measured using a Somedic hand-held pressure algometer at three sites: 1) The centre of the patella, 2) the tibialis anterior muscle and 3) a remote site on the lateral epicondyle. For the assessment of CPM, experimental pain was induced to the contralateral hand by immersion into a cold water bath ...
Despite an elusive pathophysiology, common characteristics are often observed in individuals with chronic low back pain (LBP). These include psychological symptoms, altered pain perception, altered pain modulation and altered muscle activation. These factors have been explored as possible determinants of disability, either separately or in cross-sectional studies, but were never assessed in a single longitudinal study. Therefore, the objective was to determine the relative contribution of psychological and neurophysiological factors to future disability in individuals with past LBP. The study included two experimental sessions (baseline and six months later) to assess cutaneous heat pain and pain tolerance thresholds, pain inhibition, as well as trunk muscle activation. Both sessions included the completion of validated questionnaires to determine clinical pain, disability, pain catastrophizing, fear-avoidance beliefs and pain vigilance. One hundred workers with a history of LBP and 19 healthy ...

The aim of the present study was to determine the acute effect of rolling massage on pressure pain threshold (PPT) in individuals with tender spots in their plantar flexor muscles. In a randomized control trial and single blinded study, tender spots were identified in 150 participants plantar flexor muscles (gastrocnemius or soleus). Then participants were randomly assigned to one of five intervention groups (n = 30): 1) heavy rolling massage on the calf that exhibited the higher tenderness (Ipsi-R), 2) heavy rolling massage on the contralateral calf (Contra-R), 3) light stroking of the skin with roller massager on the calf that exhibited the higher tenderness (Sham), 4) manual massage on the calf that exhibited the higher tenderness (Ipsi-M) and 5) no intervention (Control). PPT was measured at 30 s and up to 15 min post-intervention via a pressure algometer. At 30 s post-intervention, the Ipsi-R (24 %) and Contra-R (21 %) demonstrated higher (p | 0.03) PPT values compared with Control and Sham.
Abstract Aims The purpose of this study was to investigate potential gender differences in pain referral patterns induced by a tonic painful mechanical stimulus. Methods Forty-five healthy adults (22 women) participated in this study. Pressure pain thresholds (PPTs) were assessed at the infraspinatus, the brachioradialis and the gastrocnemius muscles on the dominant side, using handheld algometry. Following this, painful pressure at the infraspinatus muscle was induced using the algometer by rapidly increasing the pressure until it reached the level of 7 cm on VAS (PVAS7). This pressure was kept constant for 60s. Upon release, the subject was asked to indicate the area of the pressure-induced pain on a digital body chart. PPT values, PVAS7 and the pain area (number of pixels) were extracted for data analysis. Results No gender differences were found in PPT values (P >0.05). The pressure needed to reach 7 cm on the VAS was significantly lower in the female group (687.4±50.5 kPa) compared with males
Labour Pain essay. Order Details/Description. Work on the comments. attach the references you use in pdf format at the end of writing process.. Definition of Pain and Description of Labour Pain. Pain is defined as a bothering sensory feeling or emotional experience and is variably described as irritating, sore, stinging, aching, throbbing, or unbearable feeling (Patel 2010). There are two categories of pain, including nociceptive and neuropathic (Macintyre & Schug 2007). Macintyre and Schug (2007) explained these categories in detail. The first category is nociceptive pain-a common category reported in clinical settings. This type of pain occurs due to trauma, tissue damage or inflammation that stimulates sensory nerve endings called nociceptors. Intense peripheral nociceptive stimuli will increase excitability of the nervous spinal cord, leading to central sensitisation in the presence of subsequent pain stimuli, increased intensity and lower pain threshold. Macintyre and Schug (2007) also ...
Neuropathic pain affects 7-10% of people, but responds poorly to pharmacotherapy, indicating a need for better treatments. Mechanistic research on neuropathic pain frequently uses human surrogate models of the secondary hyperalgesia that is a common feature of neuropathic pain. Experimentally induced secondary hyperalgesia has been manipulated with pharmacological and non-pharmacological methods to clarify the relative contributions of different mechanisms to secondary hyperalgesia. However, this literature has not been systematically synthesised. The aim of this systematic review is to identify, describe, and compare methods that have been used to manipulate experimentally induced secondary hyperalgesia in healthy humans. A systematic search strategy will be supplemented by reference list checks and direct contact with identified laboratories to maximise the identification of data reporting the experimental manipulation of experimentally induced secondary hyperalgesia in healthy humans.

Quantum information processors promise fast algorithms for problems inaccessible to classical computers. But since qubits are noisy and error-prone, they will depend on fault-tolerant quantum error correction (FTQEC) to compute reliably. Quantum error correction can protect against general noise if-and only if-the error in each physical qubit operation is smaller than a certain threshold. The threshold for general errors is quantified by their diamond norm. Until now, qubits have been assessed primarily by randomized benchmarking, which reports a different error rate that is not sensitive to all errors, and cannot be compared directly to diamond norm thresholds. Here we use gate set tomography to completely characterize operations on a trapped-Yb+-ion qubit and demonstrate with greater than 95% confidence that they satisfy a rigorous threshold for FTQEC (diamond norm ≤6.7 × 10−4). Quantum computation will depend on fault-tolerant error correction, which requires the chance for errors to occur to be

This systematic review and meta-analysis revealed four important findings: (1) patients with diabetes without symptoms of DSPN already show loss of function of small-diameter nerve fibers; (2) loss of small-diameter nerve fiber function is progressive across the diabetes groups (diabetes without DSPN vs diabetes with non-painful DSPN; diabetes with non-painful DSPN vs diabetes with painful DSPN); (3) there is no overall gain of function of small-dimeter nerve fibers in patients with painful DSPN; and (4) central nervous system pain modulation mechanisms are understudied in diabetes with or without DSPN.. This review demonstrated that loss of small-diameter nerve fiber function already occurs in patients with diabetes without symptoms of DSPN. In clinical settings, DSPN is typically diagnosed based on patient-reported symptoms. Therefore, early signs of DSPN may be overlooked unless a specific evaluation of the somatosensory pathways is performed. Routine electrodiagnostic test methods ...
When it comes to pain, guys may be tougher than gals because they have more of a particular type of protein, new research suggests. Two studies published online this week by the Proceedings of the National Academy of Sciences implicate proteins known as GIRKs in sex-based differences in pain sensitivity in mice. The findings could help researchers develop new gender-specific treatments for discomfort. Previous research had shown that males tend to have a higher threshold for pain than females do and that medications affect the sexes differently, although the precise mechanism remained unclear. In the new work, scientists tested analgesic drugs on mice unable to produce the GIRK2 protein. Allan I. Basbaum of Rockefeller University and his colleagues found that male mutants had lower pain thresholds than normal male mice. Female mutants exhibited a tolerance comparable to that of their normal counterparts, however, suggesting that GIRK2 is responsible for sex differences in pain sensitivity. Male ...
I need to know if anyone has anything like I have and were you able to resolve this problem. 20 yrs. or so ago I was diagnosed with crohns and uc. 2 yrs. after my ileostomy surgery I started having awful rectal pressure pain and to this day 18 yrs later Im still in the same disabling pain. I have tried every treatment, probe, medicine, pain management,injection,etc. and also acupuncture. Nothing has helped me. I take darvon, but this does next to nothing. My bottom feels as though I have a 30 lb. weight pushing down causing great pressure pain. I would deeply appreciate any response from anyone. Surgery is not an option because they are afraid they might puncture something inside. Thanks to anyone taking the time to read my message. Yoani ...

Methysergide has been shown, in vitro and in vivo, to inhibit or block the effects of serotonin, a substance which may be involved in the mechanism of vascular headaches. Serotonin has been variously described as a central neurohumoral agent or chemical mediator, as a headache substance acting directly or indirectly to lower pain threshold, as an intrinsic motor hormone of the gastrointestinal tract, and as a hormone involved in connective tissue reparative processes ...

Animal models with an eco-ethological relevance can help in identifying novel and reliable stress-related markers. To this end, 3-month-old C57BL/6J male mice were exposed to social defeat (SD) stress for 10 days as this stressor shows good face and predictive validity for several models of human affective disorders including depression, social phobia and post-traumatic stress disorder. Social avoidance and pain threshold were assessed 24 h and 4 weeks after the end of SD stress, while corticosterone was assayed at the beginning and at the end of the stressful procedure (days 1 and 10). SD subjects were characterized by increased corticosterone levels (30 min following stress exposure), increased latency to approach the social target in the short-term as well as increased emotionality in the long-term. Moreover, an increase in nociceptive threshold (stress-induced analgesia) was found both in the short-term and 4 weeks after the end of stress. These data indicate that the SD paradigm is able to induce
Ethnic differences in central sensitization of pain processing and stress-relevant endogenous pain regulatory mechanisms were examined. Forty-four African Americans (AAs; 50% women) and 44 non-Hispanic Whites (nHWs; 50% women) matched for socioeconomic status, were tested for pain responses to the temporal summation of heat pulses and ischemic and cold pain. Resting and stress blood pressure (BP) and norepinephrine (NE) were assessed. AAs had heightened pain responses to all 3 pain tasks relative to nHWs. In nHWs, higher BP and NE were related to reduced pain. In AAs, there was no relationship between BP and pain, but higher NE was related to increased pain. This study provides evidence for ethnic differences in centrally mediated pain and extends prior research demonstrating ethnic differences in endogenous pain regulatory mechanisms. These results have implications for understanding biobehavioral factors contributing to ethnic disparities in clinical pain ...

Toy-related injuries have increased significantly in the past decade, in particular those related to ride-on toys. This increase has been attributed to movement related events such as falls and inertial impacts. Furthermore, children with disabilities have been reported to be at a greater risk of being injured, and are therefore more susceptible to toy-related injuries. Although, efforts are being made to modify ride-on toys as a method for increasing quality of life in children with disabilities, there are very limited pediatric safety studies regarding children with disabilities and modified ride-on toys. This manuscript presents a systematic review of literature summarizing the current state of toy-related injuries including children with and without disabilities. Children exposed to inertial impacts in motor vehicle crashes have also been reviewed to present current pediatric safety testing methodologies and injury tolerance thresholds. Out of 2608 articles, 10 studies were included regarding
There are two steps to successful oxygenation.. The first step is the oxygenation of the lungs and blood.. We all successfully complete this first step (except in case of serious illness) because we all have maximum oxygen saturation in the blood. If in doubt, you can measure it now with an oximeter.. Whether its a sick person close to death or an overpowered yogi hidden in a cave in the Himalayas, our oxygen saturation in the blood is always maximal (96 -100%)!. The second step is oxygenation of our cells.. They are the ones who need it to produce energy. And we have seen that the key to oxygenating your cells is the CO2 (carbon dioxide) produced inside your cells.. This concentration of CO2 is what differentiates us all, not only our level of energy but also our level of stress.. Just as for your energy level, your stress level is dependent on a single physiological variable: your CO2 tolerance threshold and your associated breathing rate (hyperventilation or calm breathing).. As you now ...
