Objectives To test the validity, practical utility, and reliability of the Actigraph GT3-X accelerometer for measurement of habitual physical activity in pet dogs. Methods In the validation study, 30 dogs wore the accelerometer for 1 day while being filmed. Accelerometer and film were synchronised and 10-minute periods of the filmed records ...
Background Continuous positive airway pressure (CPAP) therapy has been shown to be effective in alleviating the underlying obstruction as well as reducing patients’ excessive sleepiness and improving their functioning and health-related quality of life. However, residual excessive sleepiness is observed in some patients even though CPAP therapy eliminates sleep apnea ...
Complaints of poor sleep and changes in sleep-wake patterns are common among old people. An understanding of the common 24-hour sleep-wake patterns and sleep satisfaction among old people is essential for effective sleep management. To this end, an exploratory study was conducted to examine the phenomenon. A set of valid ...
The purpose of this study was to examine the validity of treadmill-based equations of two commonly used uniaxial accelerometers to estimate energy expenditure (EE) during activities of daily living in children. Twelve subjects with mean (SD) age 11.4 (0.4) years engaged in a choreographed routine consisting of three activities (sweeping, bowling, and ...
Purpose To determine the validity and reproducibility of a self-administered physical activity questionnaire that assesses the frequency, intensity, and duration of recreational, household, and occupational activity in women. Methods The questionnaire was administered by mail twice to 131 participants 1 yr apart. During this interval, participants completed four 1-wk activity logs corresponding ...
This study examined the validity and reliability of survey items measuring one-week recall of physical activity (PA) and examined differences by weight status. A sub-aim of the study was to objectively assess the intensity of activity that most closely matches self-report. A questionnaire was administered to adults twice, three days ...
Purpose To establish the validity and reliability of the GPAC for measuring physical activity and geographic location. Methods 20 subjects wore both the GRAC and an Actigraph while walking on a treadmill at 3,4, or 5 mph in a randomized order. In addition 24 subjects were asked to wear the GPAC and to record ...
It is important that we have valid tools for assessing physical activity at various ages, and this becomes particularly important with longitudinal research. The purpose of this study was to develop and validate and adult version of the Physical Activity Questionnaires for Older Children (PAQ-C) and Adolescents (PAQ-A) To examine ...
The principal aim of the present study was to examine the validity of the Computer Science and Applications (CSA) activity monitor during level walking in coronary artery disease (CAD) patients. As a secondary aim, we evaluated the usefulness of two previously published energy expenditure (EE) prediction equations. Thirty-four subjects (29 men ...
Purpose To evaluate the validity of a uni-axial accelerometer (MTI Actigraph) for measuring physical activity in people with acquired brain injury (ABI) using portable indirect calorimetry (Cosmed K4b2) as a criterion measure. Methods Fourteen people with ABI and related gait pattern impairment (age 32 +/- 8 yr) wore an MTI Actigraph ...
