Effect of Wearing a Tight Waist Belt on the Sagittal Kinematics of the Pelvis during Sit-to-Stand

抄録

[Purpose] The purpose of the present study was to evaluate the effect of a tight waist belt on the human musculoskeletal system by assessing sagittal pelvic kinematic data during the sit-to-stand (STS) maneuver. [Subjects] Twelve asymptomatic males were recruited and three belt conditions were used during the STS. Sagittal kinematic data of pelvic motion were collected using a 3D motion-capture device [Results] The changes of the anterior pelvic tilt during the STS were significantly greater in the tight waist-belt condition than in the no-belt condition. [Conclusion] The results of this study show that wearing a tight waist belt increases anterior pelvic motion.
