Abstract
[Objective] This study aimed to determine the effects of pelvis-lower extremity alignment and physical function on the quality of movement control while standing on one leg. [Methods] This study included 39 healthy subjects who were classified into a group with good movement control function and a group with poor movement control while standing on one leg. The differences in pelvis-lower extremity alignment and physical function between the groups were compared. [Results] The group with good movement control function while standing on one leg showed a significant difference in the pelvis neutral position in the standing posture.(p<0.05) The group with poor movement control function while standing on one leg showed a significant difference in positive knee extension of Thomas test(p<0.05). The pelvis neutral position and posterior tilt in the standing posture showed moderate effect. [Conclusion] Pelvis alignment and muscle function evaluation may contribute to the assessment of movement control while standing on one leg.
