Actigraphy: The measurement and recording of MOTOR ACTIVITY to assess rest/activity cycles.Sleep: A readily reversible suspension of sensorimotor interaction with the environment, usually associated with recumbency and immobility.Sleep Disorders, Circadian Rhythm: Dyssomnias associated with disruption of the normal 24 hour sleep wake cycle secondary to travel (e.g., JET LAG SYNDROME), shift work, or other causes.Sleep Disorders: 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)Polysomnography: Simultaneous and continuous monitoring of several parameters during sleep to study normal and abnormal sleep. The study includes monitoring of brain waves, to assess sleep stages, and other physiological variables such as breathing, eye movements, and blood oxygen levels which exhibit a disrupted pattern with sleep disturbances.Wrist: The region of the upper limb between the metacarpus and the FOREARM.Wakefulness: A state in which there is an enhanced potential for sensitivity and an efficient responsiveness to external stimuli.Sleep Initiation and Maintenance Disorders: Disorders characterized by impairment of the ability to initiate or maintain sleep.

In mammals, melatonin is produced by the PINEAL GLAND. Its secretion increases in darkness and decreases during exposure to light. Melatonin is implicated in the regulation of SLEEP, mood, and REPRODUCTION. Melatonin is also an effective antioxidant.Activity Cycles: Bouts of physical irritability or movement alternating with periods of quiescence. It includes biochemical activity and hormonal activity which may be cellular. These cycles are shorter than 24 hours and include sleep-wakefulness cycles and the periodic activation of the digestive system.Reproducibility of Results: The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.Monitoring, Physiologic: The continuous measurement of physiological processes, blood pressure, heart rate, renal output, reflexes, respiration, etc., in a patient or experimental animal; includes pharmacologic monitoring, the measurement of administered drugs or their metabolites in the blood, tissues, or urine.Questionnaires: 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.Fatigue: 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.Time Factors: Elements of limited time intervals, contributing to particular results or situations.Analysis of Variance: A statistical technique that isolates and assesses the contributions of categorical independent variables to variation in the mean of a continuous dependent variable.Severity of Illness Index: Levels within a diagnostic group which are established by various measurement criteria applied to the seriousness of a patient's disorder.Apathy: Lack of emotion or emotional expression; a disorder of motivation that persists over time.Dementia: An acquired organic mental disorder with loss of intellectual abilities of sufficient severity to interfere with social or occupational functioning.

The intellectual decline is usually progressive, and initially spares the level of consciousness.Alzheimer Disease: A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS. (From Adams et al., Principles of Neurology, 6th ed, pp1049-57)Video Recording: The storing or preserving of video signals for television to be played back later via a transmitter or receiver. Recordings may be made on magnetic tape or discs (VIDEODISC RECORDING).Duodenoscopy: Endoscopic examination, therapy or surgery of the luminal surface of the duodenum.Stress Disorders, Post-Traumatic: A class of traumatic stress disorders with symptoms that last more than one month. There are various forms of post-traumatic stress disorder, depending on the time of onset and the duration of these stress symptoms. In the acute form, the duration of the symptoms is between 1 to 3 months. In the chronic form, symptoms last more than 3 months. With delayed onset, symptoms develop more than 6 months after the traumatic event.Sleep, REM: A stage of sleep characterized by rapid movements of the eye and low voltage fast pattern EEG. It is usually associated with dreaming.Brain-Derived Neurotrophic Factor: A member of the nerve growth factor family of trophic factors. In the brain BDNF has a trophic action on retinal, cholinergic, and dopaminergic neurons, and in the peripheral nervous system it acts on both motor and sensory neurons. (From Kendrew, The Encyclopedia of Molecular Biology, 1994)Memory: Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.Recognition (Psychology): The knowledge or perception that someone or something present has been previously encountered.Mental Recall: The process whereby a representation of past experience is elicited.Memory, Episodic: Type of declarative memory, consisting of personal memory in contrast to general knowledge.Memory Disorders: Disturbances in registering an impression, in the retention of an acquired impression, or in the recall of an impression. Memory impairments are associated with DEMENTIA; CRANIOCEREBRAL TRAUMA; ENCEPHALITIS; ALCOHOLISM (see also ALCOHOL AMNESTIC DISORDER); SCHIZOPHRENIA; and other conditions.Sleep Apnea, Obstructive: A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)Antihypertensive Agents: Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism. Among the antihypertensive agents are DIURETICS; (especially DIURETICS, THIAZIDE); ADRENERGIC BETA-ANTAGONISTS; ADRENERGIC ALPHA-ANTAGONISTS; ANGIOTENSIN-CONVERTING ENZYME INHIBITORS; CALCIUM CHANNEL BLOCKERS; GANGLIONIC BLOCKERS; and VASODILATOR AGENTS.Hypertension: Persistently high systemic arterial BLOOD PRESSURE.

Pilot study of a cell phone-based exercise persistence intervention post-rehabilitation for COPD. (6/483)

OBJECTIVE: To determine the feasibility and efficacy of a six-month, cell phone-based exercise persistence intervention for patients with chronic obstructive pulmonary disease (COPD) following pulmonary rehabilitation. METHODS: Participants who completed a two-week run-in were randomly assigned to either MOBILE-Coached (n = 9) or MOBILE-Self-Monitored (n = 8). All participants met with a nurse to develop an individualized exercise plan, were issued a pedometer and exercise booklet, and instructed to continue to log their daily exercise and symptoms. MOBILE-Coached also received weekly reinforcement text messages on their cell phones; reports of worsening symptoms were automatically flagged for follow-up. Usability and satisfaction were assessed. Participants completed incremental cycle and six minute walk (6MW) tests, wore an activity monitor for 14 days, and reported their health-related quality of life (HRQL) at baseline, three, and six months. RESULTS: The sample had a mean age of 68 +/-11 and forced expiratory volume in one second 18% predicted. Participants reported that logging their exercise and symptoms (FEV(1)) of 40 +/- was easy and that keeping track of their exercise helped them remain active. There were no differences between groups over time in maximal workload, 6MW distance, or HRQL (p > 0.05); however, MOBILE-Self-Monitored increased total steps/day whereas MOBILE-Coached logged fewer steps over six months (p =0.04). CONCLUSIONS: We showed that it is feasible to deliver a cell phone-based exercise persistence intervention to patients with COPD post-rehabilitation and that the addition of coaching appeared to be no better than self-monitoring. The latter finding needs to be interpreted with caution since this was a purely exploratory study. TRIAL REGISTRATION: ClinicalTrials.gov (NCT00373932).  (+info)

Characterizing recovery of sleep after four successive night shifts. (7/483)

The purpose of this study was to characterize the recovery pattern of sleep following simulated, four successive night shifts in ten healthy men (22.9 + or - 3.2 yr). Poor sleep was defined as sleep efficiency of 80% or lower as determined actigraphically. The results showed that four (rapid, slow, pseudo, and incomplete) patterns of sleep recovery were observed over three recovery sleep periods. The rapid and slow recovery pattern represented immediate and slow return to baseline level prior to the nightshifts, respectively. The pseudo recovery pattern demonstrated poor sleep at the 3rd recovery sleep period, despite transient recovery at the 2nd sleep period. The incomplete recovery pattern was characterized by consistently poorer sleep during the entire recovery period. The correlation analysis indicated that sleep habits (bed time and variation of wake time) prior to the experiment were significantly related to the recovery patterns, rather than performance and alertness during the night shifts.  (+info)

Sex differences in subjective and actigraphic sleep measures: a population-based study of elderly persons. (8/483)

STUDY OBJECTIVES: To investigate and explain sex differences in subjective and actigraphic sleep parameters in community-dwelling elderly persons. DESIGN: Cross-sectional study. SETTING: The study was embedded in the Rotterdam Study, a population-based study. PARTICIPANTS: Nine hundred fifty-six participants aged 59 to 97 years. INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: Participants wore an actigraph and kept a sleep diary for an average of 6 consecutive nights. Subjective sleep quality was assessed with the Pittsburgh Sleep Quality Index. Unadjusted sex differences in sleep parameters were assessed with t tests. Women reported shorter total sleep time, a less favorable sleep-onset latency, lower sleep efficiency, and worse global sleep quality, as compared with men. When assessed with actigraphy, however, women were found to have longer and less-fragmented sleep than men. Sex differences in diary-reported sleep duration and other subjective sleep parameters were attenuated by adjustment for marital status, the use of sleep medication, and other covariates, but all sex differences remained significant in a multivariate-adjusted model. Sex differences in actigraphic sleep parameters were barely attenuated by multivariate adjustment, although the shorter actigraphically measured sleep duration in men was partly explained by their higher alcohol consumption. Some covariates (eg, sleep medication) had a different relationship with diary-reported or actigraphic total sleep time in men and women. CONCLUSIONS: If assessed by diary or interview, elderly women consistently reported shorter and poorer sleep than elderly men. In contrast, actigraphic sleep measures showed poorer sleep in men. These discrepancies are partly explained by determinants of sleep duration, such as sleep medication use and alcohol consumption.  (+info)

The strength of the study is the combined use of mechanical setup with free living confirmation of the comparison. Furthermore, we used different batches of the same Actigraph generation and the newer activity monitors were randomly picked among more than 400 monitors compiled by three batches (bought at three different time points in the period 2009-2010). We also used multiple amplitudes of displacement within the range of displacement observed in human movement [27]. Taken together this increases the generalizability of our findings to other batches of Actigraphs and the performance within the displacement amplitude in humans.. The study also had some limitations. The activity monitors were acquired from different study centers and have been used by several different field investigators. Therefore we do not have complete knowledge of service history and frequency of use. To rule out batch differences we reran the protocol using six GT3X monitors randomly picked from an independent batch and ...

There is limited evidence on the prospective association of time spent in activity intensity (sedentary (SED), moderate (MPA) or vigorous (VPA) physical activity) and dietary intake with adiposity indicators in young people. This study aimed to assess associations between (1) baseline objectively measured activity intensity, dietary energy density (DED) and 4-year change in adiposity and (2) 4-year change in activity intensity/DED and adiposity at follow-up. We conducted cohort analyses including 367 participants (10 years at baseline, 14 years at follow-up) with valid data for objectively measured activity (Actigraph), DED (4-d food diary), anthropometry (waist circumference (WC), %body fat (%BF), fat mass index (FMI), weight status) and covariates. Linear and logistic regression models were fit, including adjustment for DED and moderate-to-vigorous physical activity. Results showed that baseline DED was associated with change in WC (β for 1kJ/g difference: 0·71; 95% CI 0·26, 1·17), ...

An emerging evidence base suggests that SSD is related to food intake. Among factory workers in Japan, SSD was associated with more snacking between meals, more irregular eating habits, less consumption of vegetables, and a greater preference for strongly flavored food.49 In the United States, a study of 459 postmenopausal women enrolled in the Womens Health Initiative examined relationships between dietary records and sleep diary and actigraphy variables.50 This study showed that SSD, measured objectively with actigraphy, was strongly associated with higher intakes of many dietary fat-related variables. ...

Seventeen participants in the MAE and 13 in the HEP group completed the study. Compared to the HEP group, people with MS who participated in a moderate-intensity aerobic exercise experienced significant improvements (P , 0.05) on the PSQI, ISI, and several objective sleep parameters measured using actigraphy. Only the serotonin levels increased significantly over the six-week period in the MAE group compared to the HEP group. The change score in serotonin (from baseline to follow up assessment) was significantly correlatedwith the change score in PSQI (r = -0.97, p , 001) and the change score in ISI (r = -0. 56, p = 0.015) only in the MAE group but not the HEP group.. ...

Neuropsychiatric symptoms form part of the clinical picture of Alzheimers disease (AD) and other dementias. Irrespective of the severity of the disease, the most frequently encountered symptom is apathy. Apathy is increasingly diagnosed in patients with neurological and psychiatric conditions. Apathy is a disorder of motivation, defined as the direction, intensity and persistence of goal-directed behaviour. Most of the current descriptions acknowledge this point and consider apathy in terms of a lack of goal-directed behaviour, cognition or emotion. The classical neuropsychiatric symptom assessments are subjective structured interview-based, using input from the caregiver and/or the patient. New technologies are likely to provide us with a more objective measure. An example is ambulatory actigraphy, consisting of a piezoelectric accelerometer designed to record arm movement in three dimensions.. The aim of the present study is to assess using actigraphy and video recording signal, AD patients ...
JCSM - A Quantitative Approach to Distinguishing Older Adults with Insomnia from Good Sleeper ControlsJCSM - A Quantitative Approach to Distinguishing Older Adults with Insomnia from Good Sleeper Controls
The present study evaluated quantitative sleep criteria to distinguish individuals with insomnia from good sleepers using two assessment methods. Sleep diary measures produced areas under the curves (AUC) in the high range (0.84-0.97), whereas actigraphy performed poorly at discriminating the two groups (AUC 0.58-0.61). The Youden Index identified SOL = 17.7 minutes, WASO = 20.7 minutes, SE awake = 92.1%, SE OOB = 83.8%, and TST = 388.1 minutes as the sleep diary measures that yielded the highest sensitivity and specificity values, with diary-measured SE awake performing best at differentiating the groups. Our study appears to be the first to examine quantitative sleep thresholds using sleep diary and actigraphy among a sample of older adults who were not required to meet specific quantitative severity thresholds for entry into the study. The absence of such entry criteria limits the circularity of the findings based on study entry criteria.. Given that actigraphy is more costly than diary ...

Study Design and Patient Selection. Our main hypothesis is that elevated circulating levels of tumor-associated cytokines could significantly alter the QOL of cancer patients through the production of circadian clock dysfunction.. A prospectively studied population of 200 consecutive metastatic colorectal cancer patients referred for systemic chronochemotherapy at Paul-Brousse Hospital, Villejuif, France served as the index population as previously reported (5). Before receiving chronochemotherapy, these patients had rest/activity monitoring with wrist actigraphy and serum cortisol rhythm assessment as part of their initial work up. The analysis of the rest/activity records allowed the ranking of the patients according to r24, a robust index of the circadian rhythmicity in activity (see below). From these 200 patients, 80 were selected based upon r24 ranking. Forty patients in the top quartile displayed near normal circadian rhythm (group I) and 40 other patients in the lowest quartile had ...

Actigraphy Movement Count per Hour:Subjects will be asked to wear an actigraphy monitor on each wrist for the duration of the 14-day study. These monitors appear and function similarly to a wristwatch. The actigraph provides a continuous measure of wrist activity and may be used to quantify nocturnal scratching behavior. A piezoelectric accelerometer records the integration of intensity, amount, and duration of stimuli in all 3 dimensions of wrist movement. Measurements are taken at 32 Hz and a summation value is recorded at the end of each 30-second epoch. The number of 30-second epochs with movement (in which acceleration was detected irrespective of the magnitude of the acceleration) is recorded and summed to give a movement score. This is divided by the duration of time in bed to produce a movement count per hour, which is a sensitive quantitative measure of scratch-associated activity ...

This study aimed to examine the validity of a range of consumer-level activity monitors across a range of variables in free-living conditions. In general, the consumer-level devices were highly accurate in measurement of steps, and quite accurate for sleep quantity. However, measures of TDEE and MVPA were less accurate, in general demonstrating moderate to strong correlations with the research-grade accelerometers, but often large MADs. Within each activity construct, the validity of the consumer-level devices varied markedly. Across the domains, the One, Zip and Pulse generally performed strongly.. Steps were generally counted with a high degree of accuracy by the consumer-level activity monitors, though two devices substantially undercounted steps (MADs of 10% for Shine and 26% for Fuelband) and hence underperformed compared to conventional pedometers (such as Yamax; [29]). The findings of the current study, favouring the Fitbit activity monitors, concur with other studies which have similarly ...

Sleep disturbance has been found to trigger a stress response with a subsequent activation of the psychoneuroimmunological (PNI) pathway associated with adverse health outcomes. This study aimed to assess the association among selected PNI biomarkers, sleep disturbances, and adverse health outcomes (depressive symptoms, physical symptoms). A stratified, quota sample (14 poor sleepers and 15 good sleepers) was drawn from a pool of healthy college women from a larger scale of study. The participants reported their sleep, stress, depressive, and physical symptoms. Wrist actigraphy was used to collect objective sleep data, and the Enzyme-Linked ImmunoSorbent Assay was used to assess PNI biomarkers. Poor sleep quality, higher stress perception, elevated serum serotonin, and lower serum interleukin-10 explained 75.3% of the variances for the depressive symptoms. Poor sleep quality along with delayed peak activity rhythms accounted 31.4% of the physical symptoms. High serotonin and tumor necrosis factor-α

Background: Epidemiologic studies examining physical activity have used self-report or the preferred objective measurement devices of pedometers or accelerometers. NHANES 2003-2004 used remuneration, in-person and express mail methods to obtain accelerometer data from 7176 individuals with 4867 (68%) providing 4+ valid days of wear. Herein we describe the experience of another national epidemiologic study that used telephone and regular mail to obtain accelerometer data.. Methods: This is an ancillary study to REGARDS, a national, population-based, longitudinal study of 30,239 blacks and whites, aged , 45 years, enrolled January 2003-October 2007. Participants were recruited from communities across all 48 of the lower United States, and include residents of 1,855 of the 3,033 US counties. Baseline evaluations were conducted through computer-assisted telephone interview (CATI), self-administered questionnaires, and an in-home visit. Participants are followed by CATI every 6 months.

This unit introduces students to the field of physical activity and health. The unit begins by exploring the benefits of physical activity and risks of sedentary behaviour and then moves on to understand physical activity participation. In this regard, common theories of behaviour change are explored as are key correlates of physical activity participation. An introduction to physical activity interventions is provided as is an introduction to the importance of physical activity in the lives of specific population sub-groups including older adults and underserved populations. Throughout the unit, students are required to source and reflect on high quality evidence in particular to design an appropriate and safe physical activity program that addresses known barriers to participation and fosters adoption and maintenance.. ...

There are currently no studies available reporting intervention effects on breaking up childrens sedentary time. This study examined the UP4FUN intervention effect on objectively measured number of breaks in sedentary time, number of sedentary bouts (, 10 mins) and total and average amount of time spent in those sedentary bouts among 10- to 12-year-old Belgian children. The total sample included 354 children (mean age: 10.9 ± 0.7 years; 59% girls) with valid ActiGraph accelerometer data at pre- and posttest. Only few and small intervention effects were found, namely on total time spent in sedentary bouts immediately after school hours (4-6PM; β = -3.51mins) and on average time spent in sedentary bouts before school hours (6-8.30AM; β = -4.83mins) and immediately after school hours in favor of children from intervention schools (β = -2.71mins). Unexpectedly, girls from intervention schools decreased the number of breaks during school hours (8.30AM-4PM; β = -23.45breaks) and increased the ...

Sleep disturbance in post-traumatic stress disorder (PTSD): a systematic review and meta-analysis of actigraphy studiesSleep disturbance in post-traumatic stress disorder (PTSD): a systematic review and meta-analysis of actigraphy studies
European Journal of Psychotraumatology. Catrin Lewis, Katie Lewis, Neil Kitchiner, Samantha Isaac , Ian Jones & Jonathan I. Bisson. https://doi.org/10.1080/20008198.2020.1767349. Abstract. Background: Sleep disturbance has been described as a hallmark symptom of posttraumatic stress disorder (PTSD). Although there are robust findings of self-reported sleep disturbance in PTSD, evidence of sleep disturbance measured using actigraphy is less certain.. Objective: To conduct a systematic review and meta-analysis to determine whether there are any significant differences between individuals with and without PTSD in actigraph-derived sleep measures.. Method: Case-control studies comparing participants with current PTSD to those without PTSD were eligible for inclusion. Sleep parameters of interest were: (1) total sleep time; (2) sleep onset latency; (3) wake after sleep onset (WASO); and (4) sleep efficiency. Data were meta-analysed as standardised mean differences (SMDs) and potential sources of ...

Abnormalities in sleep and circadian rhythms are central features of bipolar disorder (BP), often persisting between episodes. We report here, to our knowledge, the first systematic analysis of circadian rhythm activity in pedigrees segregating severe BP (BP-I). By analyzing actigraphy data obtained from members of 26 Costa Rican and Colombian pedigrees [136 euthymic (i.e., interepisode) BP-I individuals and 422 non-BP-I relatives], we delineated 73 phenotypes, of which 49 demonstrated significant heritability and 13 showed significant trait-like association with BP-I. All BP-I-associated traits related to activity level, with BP-I individuals consistently demonstrating lower activity levels than their non-BP-I relatives. We analyzed all 49 heritable phenotypes using genetic linkage analysis, with special emphasis on phenotypes judged to have the strongest impact on the biology underlying BP. We identified a locus for interdaily stability of activity, at a threshold exceeding genome-wide ...
Changes in Physical Activity, Physical Function and Cognitive Function with Transition to Retirement LivingChanges in Physical Activity, Physical Function and Cognitive Function with Transition to Retirement Living
Physical activity is associated with slower physical and cognitive decline with aging. However, there are many barriers to physical activity among community-dwelling older adults. Retirement living may facilitate physical activity by reducing health, social, and environmental barriers for seniors. The purpose of this thesis was to: (1) quantify changes in physical activity and physical function over the transition to retirement living; (2) examine the relationship between participant characteristics and physical activity in retirement living; and (3) describe the relationship between change in physical activity and change in physical and cognitive function. Older adults on the wait-lists for or living in retirement living were recruited. Physical activity was assessed with the Actigraph activity monitor and the CHAMPS activity questionnaire. Physical function was measured with the Senior Fitness Test. Cognitive function was assessed with a 45-minute test battery that assessed a variety of ...

Principal Investigator: Stephen E. Olvey, M.D.. Institution: Department of Neurological Surgery, University of Miami School of Medicine, 1501 N.W. 9th Avenue, Miami, FL 33136. The Development of a System Using Triaxial Accelerometers to Measure Head Motion and Energy Exposure During High Velocity Vehicular Impact. Update. Head injury is a serious safety concern in motorsports. In Indy car events from 1985 - 1989, 367 crashes occurred involving 413 drivers, 38 of these drivers sustained 48 injuries. Despite the use of helmets and other safety equipment, 29.2% of these injuries were closed head injuries. One of the most severe types of closed head injuries, diffuse axonal injury (DAI), occurs as a result of high velocity acceleration/ deceleration of the head with a rotational component that may cause widespread neuroanatomical and neurophysiological damage. Athletes in a variety of sports who survive this type of injury can be afflicted with persistent neurological deficits.. Triaxial ...

This small exploratory study supports previous findings that self-reported sleep disturbance predicted exacerbation of next-day symptoms in women with IBS and extends this relationship using an objective sleep measure, the study concluded, which was led by Diana Taibi Buchanan, Ph.D. The study adds further evidence that sleep quality predicts subsequent IBS symptoms, but not the converse. The findings from this small study support the importance of additional longitudinal research to further understand the relationships between sleep and IBS ...

Assessment4
  • Wearable accelerometers (such as an actigraphy AMI, Ambulatory Monitors Inc., USA) enable long-term recording of a patient's movement during activities of daily living [ 6 , 7 ] and, hence, might be the best choice for a device for quantitative assessment of the symptoms due to various diseases [ 8 ]. (hindawi.com)
  • Ceratto S, Dalmasso P, Miniero R, Montezemolo CD, Savino F. Comparison between actigraphy and parental reporting for sleep assessment in hospitalized infants. (minervamedica.it)
  • Current analysis tools have focused on sleep assessment and use graphical displays with zoom in/out capabilities and basic summary statistics (e.g., mean and standard deviation of the activity level within a patient) that enable the clinician to view a single patient s actigraphy data to identify aberrant patterns of activity.

  • 2. An ambulatory, extended-wear electrocardiography and syncope sensor monitor recorder (14) according to Claim 1, wherein the syncope sensor comprises at least one of a patient-mediated tactile feedback syncope button (66) and an actigraphy-based syncope sensor (64). (google.co.uk)
  • 3. An ambulatory, extended-wear electrocardiography and syncope sensor monitor recorder (14) according to Claim 2, wherein the syncope events comprise at least one of a syncope event identified by a patient (10,11) and a syncope event identified by the actigraphy-based syncope sensor (64) based on actigraphy filtering criteria comprising at least one of a falling event and a postural change event.

Methods2
  • To increase the use of actigraphy as a tool for objectively measuring fatigue, additional robust data models and statistical data analysis methods and software are needed. (docplayer.net)
  • 2. We will apply existing and develop new advanced statistical and visualization methods for actigraphy data and include them in the data model defined in Aim 1. (docplayer.net)

Data11
  • Actigraphy data can best be described as functional data. (docplayer.net)
  • In this paper, we will present exploratory graphical displays for various components of functional actigraphy data. (docplayer.net)
  • Key Words: Actigraphy, Functional Data Analysis, Visualization. (docplayer.net)
  • Group comparisons reduce multivariate actigraphy data to summary statistics (e.g., mean, standard deviation) which throws out important information such as the pattern of activities. (docplayer.net)
  • Furthermore, actigraphy data show considerable variability within and between patients, so that landmark analyses may not be powerful enough to detect changes in activity levels due to disease or treatment response. (docplayer.net)
  • We will define an object oriented data model for actigraphy and patient level data. (docplayer.net)
  • This data model will use object oriented programming strategies programmed in the R open source statistical software programming language to store patient level (e.g., diagnoses, demographics, clinical variables, treatments, medications, previous history, research information) and actigraphy level data in a relational database. (docplayer.net)
  • 3. To validate and improve the tools developed in Aims 1 and 2, we will prospectively collect actigraphy data under controlled experimental conditions (for calibration and methodology development) and in several patient subgroups. (docplayer.net)
  • Actigraphy has the advantage of being able to record data over long periods of time while the subject carries out his or her normal routine. (oxfordhandbooks.com)
  • Actigraphy data were downloaded using-proprietary software to generate an individual-sleep report. (scirp.org)
  • Actigraphy and weight gain data were reviewed for 751 women. (eurekalert.org)

  • Kristin E. Schwab, M.D., from the University of California in Los Angeles, and colleagues conducted a systematic review of ICU-based studies that used actigraphy as a surrogate measure of sleep in critically ill patients . (medicalxpress.com)
Quality3
  • HealthDay)-Using actigraphy as a measure of sleep, critically ill patients in the intensive care unit (ICU) show wide ranges of sleep quality and quantity, and actigraphy may estimate higher sleep durations than other measures, according to a review published in the September issue of the Annals of the American Thoracic Society . (medicalxpress.com)
  • Actigraphy is not the most reliable way to track sleep quality or even the time a person is actually asleep. (news-medical.net)
  • Purpose: This study aimed to determine the feasibility and acceptability of actigraphy to monitor sleep quality and quantity in healthy self-rated good sleeper adults at home-based settings. (scirp.org)
