ABSTRACT
Parkinson's disease (PD) is considered a movement disease; it is a progressive and degenerative neurological disorder, causing disabling motor dysfunctions. Investigate the body instability of PD patients through the stabilometry test is the aim of this study. A sample of 40 participants with PD were staged between the stages of the disease using Hoehn and Yahr Modified Scale 1.5 to 3.0 in static posture with eyes open and closed to assess stabilometry in the distance from the center of pressure (CoP), as well as anteroposterior (AP) and mediolateral axis (ML). There were found no differences in the body oscillation variables on the AP and ML axis. There was a difference in CoP displacement and oscillation speed between stage 1.5 to 3.0. It was concluded that participants with PD in stage 3.0 had greater distances from the CoP and greater speed of body sway, and that these instabilities become more evident with the progression of the disease.
