Fig. 2From: Effects of interactive video-game–based exercise on balance in older adults with mild-to-moderate Parkinson’s diseaseSchematic diagram of the multidirectional reaching task. The stepping mat was placed 60 cm in front of the monitor. a: Participants performed interactive multidirectional reaching tasks by following the target appearing on the television screen, with movements tracked by infrared photosensors in the controllers. b & c: For the antero-posterior stepping practice, participants stood 12 cm away from the mat in front/behind and stepped onto the target area according to the monitor cues. d & e: For the medial-lateral stepping practice, participants stood on the right/left side of mat (starting area) and stepped onto the target area according to the monitor cues. For forward–backward and medial–lateral stepping, the floor and mat were marked to ensure that participants started and ended in the same placeBack to article page
