Postural and Suprapostural Performance During Dual Tasking in Patients With Parkinson's Disease
Conditions
Keywords
Parkinson, dual-task training, attention, electroencephalogram (EEG)
Brief summary
(1) postural and suprapostural performance of a dual task would be differently affected by the strategy of task prioritization and (2) the cortical activation is different according to attentional focus strategies.
Detailed description
These hypothesis would be tested by gait performance, suprapostural accuracy and relative power spectrum of EEG.
Interventions
BEHAVIORALWeight-shifting training
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.
