The purpose of this study is to explore the TURN180 test ability to evaluate the risk of falling in the elderly population and compare it to the known gold standard clinical test. This is a validation study of balance and mobility tests using a three-group sample of convenience. The independent elderly subjects (n=75) will be divided into three groups according to their falls history and undergo four balance tests: Timed "Up and Go" test (TUG), Tinetti Balance Test (Tinetti), Berg Balance Scale (BBS). The participants will be videotaped while performing the TUG test. Basic temporospatial aspects of turning during walking such as the number of steps taken during the turn and the time taken to accomplish the turn will be measured using both the slow-motion and stop-action capabilities of the VCR system and a time-code processor.
