Purpose: The purpose of this study was to determine the effective weight-shifting training. The subjects were 33 normal
adults who hadn’t experienced lower extremity injury.
Methods: Weight-shifting training was classified into 3 performances for toe off, heel off, toe off with hip external rotation. In standing position, subjects were performed the 3 performances in dominant side. Non-dominant side supported their body weight during weight-shifting trainings. Muscle activities and Foot pressure of non-dominant leg were recorded during 3 Weight-shifting trainings. The muscle activities of the gluteus maximus, gluteus medius, vastus medialis, vastus lateralis, Biceps femoris, semitendinosus muscles were recorded by EMG according 3 weight-shifting training. In foot pressure, we evaluated value of total Pressure ratio, front and back moving, lateral and medial moving, average of pressure, Fore and Rear pressure using by Gaitview Pro.
Results: The results of this study were that semitendinosus significantly increased among three weight-shifting training(p<0.05). Biceps femoris showed significantly difference only toe off with hip external rotation(p<0.05). In three weight-shifting training, total Pressure-ratio, front moving, lateral and medial moving, average of pressure, Fore and Rear pressure were significantly increased in toe off with hip external rotation. Back-moving significantly increased in toe off(p<0.05).
Conclusion: The result of this study suggests that weight-shifting during toe off with hip external rotation is effective
method on weight shifting to affected side for stroke patient.
