Abstract

OBJECTIVE
The ability to get up from a chair is an important component in maintaining independence and a prerequisite for upright mobility for stroke patients. The purpose of this study was to compare the sit-to-stand movement in stroke patients with that in healthy adult. METHOD: Twenty-three stroke patients and thirty-seven young healthy subjects were included in this study. Subjects sat on an adjustable chair with their feet on force plates and performed the standing up movement at a self-paced, comfortable speed. The study patients were tested barefoot. The changes in joint angle, maximal moment, power, and ground reaction force in lower limb were calculated using 3 dimensional motion analyzer throughout the sit-to-stand transfer.
RESULTS
The mean time needed was significantly longer in stroke patients than in young healthy subjects. Pelvic tilting and hip flexion angle at initial and final angle were significantly greater in stroke patients than in young healthy subjects. Maximal momentum, power and change of ground reaction force in ankle joint were significantly lower in stroke patients than in young healthy subjects. Hip external rotation angle at standing point showed significant correlation with maximal hip external rotation and slow walking speed during the comfortable walking.
CONCLUSION
We concluded that the analysis of sit-to-stand movement in stroke patients may provide a useful guide for gait recovery and training.
