To understand the kinetic characteristics during initiation process of gait from standing in Parkinson's disease (PD) vertical ground reaction forces and center of pressure (COP) were measured with two Kistler force platforms in 11 patients with PD (Hoen and Yahr scale III) and 15 age matched controls.

The duration of initiation of gait(IOG) was increased and displacement of net COP was decreased in the PD group compared to the controls.

This findings and methods could be used to quantify delay in reaction time and bradykinesia in PD.

The trunk and pelvis movements in gait of 7 patients with Parkinson's disease and 23 normal subjects were studied using an electromagnetic tracking instrument. In patients with the disease, the pelvis and the trunk do not rotate or in the same direction in the transverse plane, whereas in normal gait they rotate in the opposite directions. In the sagittal plane, although amplitude of the angular displacement was extremely diminished in patients, the trunk and the pelvis rotate in the same direction as in normal subjects. In the coronal plane, there was no consistent tendency between them. The ranges in angular displacements of the pelvis in patients was smaller than in normal subjects in all planes, but of trunk in only transverse plane. The range in absolute angular displacement of the trunk are not significantly different from that in relative to the pelvis except for in the coronal plane although in normal subjects, the former is smaller than the latter except in the sagittal plane. These results indicate that in patients with Parkinson's disease, trunk movement itself is affected especially in the transverse plane and pelvic motions are more restricted in all planes than trunk movements.
