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)
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)
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 Advances in sensor technologies and signal processing techniques provide a method to accurately measure walking activity in the home and community. Activity monitors geared toward consumer or patient use may be an alternative to more expensive monitors designed for research to measure stepping activity. OBJECTIVE The objective of this study was(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)
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)
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)
OBJECTIVE To determine the ability of the 6-minute walk test (6MWT) and other commonly used clinical outcome measures to predict home and community walking activity in high-functioning people with stroke. DESIGN Cross-sectional. SETTING Outpatient physical therapy clinic. PARTICIPANTS Participants (N=32) with chronic stroke (n=19; >6mo poststroke)(More)
Standardized outcome measures (OMs) are a vital part of evidence-based practice. Despite the recognition of the importance of OMs, recent evidence suggests that the use of OMs in clinical practice is limited. Selecting the most appropriate OM enhances clinical practice by (1) identifying and quantifying body function and structure limitations; (2)(More)
To help separate out the contributions of the somatosensory and vestibular systems to postural and sway control, short (1, 4 and 16 mm) anterior translations of lengths less than the normal sway path length were made of a platform upon which blindfolded young adult test subjects (n=12) stood or sat. Acceleration detection thresholds from these short moves(More)
