BeatPark: Self-rehabilitation in Walking With Parkinson's Disease

Physical activity has beneficial effects on the quality of walking for persons with Parkinson's disease (PD). However, regular physical activity is still limited in most patients' daily lives. The rhythm of music makes you want to move whether you are sick or not. In addition, it has been found that in people with PD, it can also improve walking by helping the participant to regain the regularity of alternating steps and a better walking dynamic (i.e. better position, better arm swinging, etc.). Studies have shown that music allows persons with PD to walk faster, with bigger steps. However, if the tempo of the music does not correspond to the participant's walking pace, instead of helping him, it can disturb him. So it seems necessary for music to help people with PD to walk better if the tempo of the music is set to match their steps. BeatPark is a smartphone application which makes it possible to synchronize the tempo of the music with the participant's walking rhythm detected thanks to feet insoles. Once synchronized to the participant's walking pace, BeatPark imperceptibly accelerates the tempo of the music to help the participant's acceleration. This clinical trial proposes to study the effects of walking rehabilitation depending on the use of music synchronized to the participant's step with BeatPark, music with random tempo or without music.
