CLINICAL ANALYSIS OF SIT-TO-STAND TRANSFER BY MEASURING GROUND REACTION FORCES

A system for clinical analysis of sit-to-stand transfer using two forc e plates is presented. Distinct time-events and phases are estimated. Illustrative parameters are also determined, such as the distribution of the vertical ground reaction forces, displacement of the center of gravity in the sagittal and frontal planes, and a comparison of the di splacement of the center of gravity and the center of pressure. These parameters indicate a symmetrical raising while keeping the middle of the body. Future applications include the validation of therapy, biofe edback and the control of closed-loop FES.
