Session Title: Parkinson's disease: Neuroimaging and neurophysiology
Session Time: 12:00pm-1:30pm
Location: Exhibit Hall located in Hall B, Level 2
Objective: The purpose of this study is to evaluate the effect of lateral wedge to balance in Parkinson’s disease.
Background: Although postural instability is the major symptoms in Parkinson’s disease (PD), dopaminergic treatment is ineffective to postural instability. Recent reports showed that somatosensory deficit is associated with postural instability and somatosensory input improved postural instability. The purpose of this study is to evaluate the effect to postural instability of standing on lateral wedges in Parkinson’s disease.
Methods: Twenty-two patients who were diagnosed as Parkinson’s disease were enrolled in this study. We obtained the range and velocity of center of pressure (COP) from forced platform with and without 10 degree wedge. Participants stood on force plate of two conditions (wedge and no wedge) with or without eye opening and closing. We compare the range and velocity of COP.
Results: The range and velocity of COP in AP and ML direction were significantly improved after standing on lateral wedge when eye closing. The range in ML direction and velocity in both direction of COP were significantly decreased when eye opening.
Conclusions: Regardless of vision, standing on lateral wedge improved postural sway in PD.
