Figure 4

Example of experiment setup. Twelve reflective markers were placed on each participant; three on the head (center of forehead, occipital protuberance and top of head), three on the trunk (left acromion, right acromion and left scapula) and three on each foot (heel, 2nd metatarsal and lateral malleolus). The subjects stepped in the middle of the rotating platform counteracting the circular motion of the platform. They held a low-friction wheel overhead and subjects in study 2 wore a modified parachute harness for added safety.
