All the participants performed Instrumented Stand and Walk (ISAW) test: they were asked to stand quietly for 30 seconds with their arms at their sides and look straight ahead, walk 5 meters, turn 180 degrees after crossing a line on the ground, and return to the initial starting position. The test was performed twice before and after the ALCT for the patients with PD and only once for HC.
