Abstract: Objectives: This study aimed to compare the sit-to-stand (STS) transfer in normal elderly subjects and people with Parkinson’s disease, using kinematic and kinetic analysis. Design: A cross-sectional cohort study using a control group and a group of individuals with Parkinson’s disease. Background: Parkinson’s disease (PD) is a progressive neurological condition that is characterized by hypokinesia, akinesia, tremor, rigidity and postural instability. In individuals with PD, falling is a common risk and occurs most frequently during walking or other locomotor activities that involve a shift in the centre of mass, an example being the daily STS transfer. This study aimed to help the clinician gain a better understanding of the biomechanical analysis of the STS transfer in individuals with PD. Methods: Fourteen subjects with PD and fourteen age matched healthy individuals performed the STS transfer at their self-selected speed from a height-standardized seat in a laboratory setting. Analysis was based on ground reaction forces, joint angles calculated from two-dimensional kinematic data, and time to complete the task. Results: Subjects with PD took longer than control subjects to complete the STS. Also, there were differences in the ground reaction forces between individuals with PD and their age-matched controls. Conclusion: In line with other findings about movement in PD, the individuals with PD were slower, exerted less force and used different strategies than age-matched controls.
