Abstract :
Freezing of gait is a debilitating symptom that affects mobility in Parkinson disease (PD) patients. In this study, we examined mean center of pressure (CoP) for patients during freezing and compared them against mean CoP during standing and walking. Patients experienced a significantly forward CoP (p<;0.01) during freezing than standing and walking, which is associated with an increased risk of falling. Absolute mean CoP differences between left and right foot represent an out of phase CoP profile during freezing. These findings can be used to suggest new strategies for fall prevention as well as freeze breaking strategies.
