BACKGROUND An ability to predict risk of future falling is needed in order to target high-risk individuals for preventive intervention. The purpose of this study was to compare the ability of different measures of postural balance to predict risk of falling prospectively in an ambulatory and independent elderly population. METHODS Balance tests were(More)
A cross-sectional study was performed to investigate the association between fear of falling and postural performance in the elderly. One hundred ambulatory and independent volunteers (aged 62-96) were subjected to five types of balance tests: (a) spontaneous postural sway, (b) induced anterior-posterior sway, (c) induced medial-lateral sway, (d) one-leg(More)
OBJECTIVE To assess the risk of falls attributable to medication use and orthostatic hypotension. DESIGN Prospective cohort study. SETTING Two self-care, apartment-style residential facilities in the Toronto area. PARTICIPANTS A total of 100 consecutive older volunteers (mean age = 83, range 62-96) who were independent in activities of daily living(More)
OBJECTIVE To determine whether an activity-based test of balance and gait is predictive of the risk of: (1) falling in situations that are related to specific tasks evaluated as part of the test, (2) experiencing falls precipitated by different classes of biomechanical events, or (3) falling in general; and to compare the predictive ability of the(More)
We assessed the accuracy and ease of use of the BladderScan (BVI 2000) portable ultrasound-based bladder volume measurement device in a geriatric outpatient population. The Geriatric Continence Clinic nurse and physician each made 73 measurements on 36 subjects. Although the correlation coefficients between the true and ultrasound measurements were highly(More)
Computer-aided design and computer-aided manufacturing (CAD/CAM) systems for the design and manufacture of limb prostheses have recently become commercially available. However, rigorous evaluations of these systems have not been performed to determine whether they produce sockets that fit as well as or better than sockets made using conventional design(More)
A method of automatically estimating the location of the bladder wall in ultrasound images is proposed. Obtaining this estimate is intended to be the first stage in the development of an automatic bladder volume calculation system. The first step in the bladder wall estimation scheme involves globally processing the images using standard image processing(More)
The American Journal of Occupational Therapl' Wheelchair users often have difficulty cooking WIth a conventIonal freestanding cooking range, in part because the 36-in. high working surface is too high for them. Barrier-free standards suggest a working surface height of 28 in. to 34 in. (710-86'5 mm) for wheelchair users (American National Standards(More)
Forty-eight below-knee amputees compared sockets designed using CANFIT computer aided design (CAD) software with sockets designed using conventional methods. Each subject was fitted by one prosthetist who used conventional techniques and one who used the CANFIT system to design the socket. Prosthetists alternated design methods for each new subject. The(More)
