Monitoring of posture allocations and activities enables accurate estimation of energy expenditure and may aid in obesity prevention and treatment. At present, accurate devices rely on multiple sensors distributed on the body and thus may be too obtrusive for everyday use. This paper presents a novel wearable sensor, which is capable of very accurate(More)
BACKGROUND AND PURPOSE Gait speed is commonly used to assess walking ability in persons with stroke. Previous research related to the psychometric properties of gait speed has been conducted primarily with individuals who were able to walk independently and/or were in the later stages of recovery after stroke. The purpose of this research was to examine the(More)
BACKGROUND The upper-extremity portion of the Fugl-Meyer Scale (UE-FM) is one of the most established and commonly used outcome measures in stroke rehabilitative trials. Empirical work is needed to determine the amount of change in UE-FM scores that can be regarded as important and clinically meaningful for health professionals, patients, and other(More)
BACKGROUND AND PURPOSE The Tinetti Performance-Oriented Mobility Assessment (POMA) is commonly used to measure balance ability in older adults. The purpose of this study was to determine the test-retest reliability and minimal detectable change (MDC) of the POMA and explore its cross-sectional and longitudinal construct validity for use in people early(More)
The purpose of current study was to assess postural control and balance self-efficacy in people with fibro-myalgia syndrome [FMS]. Thirty-two females with FMS completed the Activity-specific Balance Confidence Scale, Berg Balance test, NeuroCom Balance Master sensory-organization test, and limits of stability. There was a high prevalence of reported falls(More)
OBJECTIVE To determine the degree to which self-selected walking speed (SSWS), maximal walking speed (MWS), and walking speed reserve (WSR) are associated with fall status among community-dwelling older adults. DESIGN WS and 1-year falls history data were collected on 217 community-dwelling older adults (median age = 82, range 65-93 years) at a local(More)
BACKGROUND This study explored the effects of diabetes mellitus (DM) and peripheral neuropathy (PN) on the ability to detect near-threshold postural perturbations. METHODS 83 subjects participated; 32 with type II DM (25 with PN and 7 without PN), 19 with PN without DM, and 32 without DM or PN. Peak acceleration thresholds for detecting anterior platform(More)
PURPOSE The purpose of this study was to determine the ability of a novel shoe-based sensor that uses accelerometers, pressure sensors, and pattern recognition with a support vector machine (SVM) to accurately identify sitting, standing, and walking postures in people with stroke. METHODS Subjects with stroke wore the shoe-based sensor while randomly(More)
Approximately one-third of people who recover from a stroke require some form of assistance to walk. Repetitive task-oriented rehabilitation interventions have been shown to improve motor control and function in people with stroke. Our long-term goal is to design and test an intensive task-oriented intervention that will utilize the two primary components(More)
The 6-minute walk test (6MWT) is commonly used to measure walking ability. The purpose of this study was to determine the test-retest reliability and concurrent and construct validity of the 6MWT in patients who were actively undergoing inpatient rehabilitation poststroke. Thirty-seven patients undergoing inpatient rehabilitation after a stroke(More)
