Abstract

<p>[Purpose] Rising from supine (RS) is an important functional movement that should be analyzed by physical therapists to improve functional ability. However, no previous study has reported kinematic data of RS. [Participants and Methods] Healthy males performed RS with trunk rotation of Sarnacki’s description. RS was recorded using four video cameras (30 fps). The local coordinate reference system was calculated using three-dimensional analysis. The joint angles of the upper extremity joints and trunk were compared between the normal speed task (n=6) and the slow speed task (n=5). The unpaired t-test was used for statistical analysis. [Results] On the supported side in the slow speed task, the angle of rotation of the trunk and internal rotation of the shoulder joint were significantly greater than in the normal speed task (p<0.05). [Conclusion] A significant increase in shoulder joint angles of the supported side in the slow speed task was useful for displacing the center of mass of the upper body within the base of support formed by the upper extremities.</p>
