Changes in movements of neck, trunk, and hip according to height and foot position during sit-to-stand.
[Purpose] The purpose of this study is to analyze changes in movements of the neck, trunk and hip according to foot position while performing sit-to-stand (STS) exercises from a height-fixed chair. [Subjects and Methods] The study subjects consisted of 22 university students (12 males and 10 females). STS was conducted using a height-fixed chair at three positions: symmetric foot position, right foot position, and left foot position. Through three-dimensional motion analyzer, the movements of the neck, trunk, and hip were analyzed. [Results] While performing STS, the height was more influential on changed in angle of the neck, trunk, and hip. Moreover, when the height of the chair and the height of the subject were not matched correctly, more effective STS could be achieved when both of feet were laid symmetrically rather than at the other two positions. [Conclusion] It is necessary to employ an appropriate chair height that is matched with the height of the patients when therapy using STS is performed.
