The Learning Effects of Task-priority Strategy on Dual-task Weight Shifting and Brain Plasticity in Patients With Parkinson's Disease

"Postural task: Participants are standing with their weak side on the force plate. During the task, they wight-shift from side to side ranging from 10 to 90 percent of their body weight.~Suprapostural task: Participants hold a tray with their arms beside the body, 90 degrees of elbow flexion. They rotate the tray left and right for 45 degrees respectively.~During their task, participants should weight-shift and rotate the tray at the same time."
