Chou SW, Wong AMK, Leong CP, Hong WS, Tang FT, Lin TH: Postural control during sit-to-stand and gait in stroke patients. Am J Phys Med Rehabil 2003;82:42–47.
Objective: To investigate the relationship of sit-to-stand and gait performance in hemiplegic stroke patients.
Design: A total of 40 chronic stroke patients with hemiplegia and 22 age-matched healthy subjects were included in this study. Data of a motion analysis system and three force platforms were collected in a rehabilitation unit of a medical center.
Results: Laboratory sit-to-stand measurement and gait analysis were evaluated in both groups via three AMTI (Advanced Mechanical Technology Inc.) force platforms and a Vicon 370 system (six high-resolution cameras and one AMTI force plate), respectively. The sit-to-stand and gait parameters of hemiplegic patients were correlated significantly, especially in rising speed and the maximal vertical force of both legs during rising.
Conclusions: Hemiplegic stroke patients, who could stand up within 4.5 sec or who had a maximal vertical force difference of less than 30% of body weight between both legs, had better gait performance than the others did.
