A Comparison of Four Approaches to Evaluate the Sit-to-Stand Movement.

The sit-to-stand test (STS) is a simple test of function in older people that can identify people at risk of falls. The aim of this study was to develop two novel methods of evaluating performance in the STS using a low-cost RGB camera and another an instrumented chair containing load cells in the seat of the chair to detect center of pressure movements and ground reaction forces. The two systems were compared to a Kinect and a force plate.

A Pilot Study to Detect Balance Impairment in Older Adults Using an Instrumented One-Leg Stance Test.

The aim of this study was to investigate whether parameters from an instrumented one-leg stance (OLS) on a force plate could provide relevant information related to fall risk in older people. Forty-two community dwelling older people including 17 fallers and 25 nonfallers, and 25 young subjects performed a OLS while standing on a force plate, with parameters related to transferring weight onto one leg and postural sway in singe-leg stance evaluated. No differences were observed between older fallers and nonfallers and the younger participants for any of the weight transfer parameters.
