Feasibility of measuring the volition level in elderly patients when using audio encouragement during gait training physical therapy

The purpose of this study is to find a method for measuring the volition level in elderly patients during gait training physical therapy. First, both the walking speed and tempo of the elderly patients were experimentally measured with a video camera under musical stimulation, however, neither walking speed nor tempo was directly related to the subjects´ will or level of enthusiasm to undergo the gait training physical therapy. Second, the Fmθ activities of EEG signals were experimentally measured while performing a psychological task at a desk. These Fmθ activities seemed to be related to the subjects´ enthusiasm, however, their high level of deviation and the influence of artifacts minimized their usefulness for this purpose.
