The subject will arrive independently at the Tel Aviv Medical Center. After explaining the course of the study and signing a consent form, the subject will be administered the MoCA questionnaire to assess the cognitive state.~During this session, the patient will undergo gait evaluation using motion sensors and an EMG device.~This meeting will last up to an hour, according to the following breakdown:~Explanation of the test (10 min) Preparing the skin (light disinfection with alcohol) for EMG adhesion (10 min.) Performing of the test (20 minutes) Summary and discharge (5 min).
The main goal of this study is to evaluate, via EMG (electromyography) system, the muscle activity in the lower limbs, to understand the contribution of the muscle activity to FOG (freezing of gait) in Parkinson's patients. The phenomenon of FOG appears in advanced cases of Parkinson's disease (PD) and can lead to an increased risk of falls. There are several approaches claiming that there is abnormal activity in the calf muscles and the freezing events in Parkinson's patients. In the clinic, monitoring FOG is done subjectively, usually through observations or through questionnaires. As a result, the information about the phenomenon may be biased and insensitive. With an electromyographic monitor (EMG), objective information about the muscular activity during normal walking and during unusual events can be obtained.
