EFFECTS OF 10 WEEKS TRAINING PROGRAM ON LOWER EXTREMITY STRENGTH AND VERTICAL REACTION FORCE DURING SIT-TO-STAND IN CHRONIC STROKE PATIENTS

Abstract

The purpose of this study was to investigate the effects of 10 weeks training program on lower extremity strength and' vertical reaction force during sit-to-stand movement in chronic stroke patients. Maximum vertical ground reaction force, difference of vertical ground reaction force between left and right foot, COP in anteriorposterior and mediolateral direction did not show any significant time main effect. However, the difference of body weight distribution between the left and right foot was decreased in experimental group after training. The peak torque generated by the flexors of the paretic limb at 60o /sec and 180o/sec in experimental group changed from baseline, an increases of 30.23% and 24.09%, respectively. These results appear that 10 weeks training program improves sit-to-stand movement and lower extremity strength in chronic stroke patients.
