Purpose The purpose of this study is to investigate the effects of pelvis movements facilitation on trunk stability, standing postural alignment and postural balance in hemiplegic patients. Methods In the case of 54 year old hemiplegia cerebral infarction patient, pelvis movements facilitation were performed for 60 minutes, 3 times per week, for 3 weeks from December 26, 2022 to January 13, 2023. Coordination of standing postural alignment, trunk stability, static and dynamic balance. standing postural alignment was evaluated through photographs, and trunk stability was evaluated through the Trunk Impairment Scale (TIS). Static and dynamic balance was assessed using the Biorescue, Timed up and go test (TUG). Results After the intervention, there was a change in the standing postural alignment against gravity, and the TIS score after intervention increased by 2 score. After intervention, pressure on the affected foot increased in Biorescue, and walking time increased as a result of TUG. Conclusions The 3 weeks of pelvis movements facilitation confirmed changes in standing postural alignment, trunk stability of hemiplegic Patient and changes in body symmetry in static and dynamic balance abilities, confirming that the intervention in this study was effective.
