Poor posture or hypertonic of the specific muscle of the pelvis is one of the major causes of the musculoskeletal problem of the low back. Asymmetry contraction of the muscles which moved the pelvis could affect the lumbosacral-hip joint. Therefore, this study analysis pelvic movement according to the asymmetric muscle contraction around the pelvis. Five Korean adult cadavers were used to evaluate the pelvic movement (F: 1, M: 4), and the average age was 83.4years. To evaluate the pelvic movement, the specimen was harvested from the first lumbar to the femur. The gluteus maximus (GMax), hamstring (Ham), erector spinae (ES), and iliopsoas (IP) which known as occur the pelvic anterior (AT) and posterior tilt (PT) were dissected to evaluate the pelvic movement. The muscle contraction was generated through the customized device which was made using the linear actuator and load cell, and this device was designed to control the leg position. To analyze the pelvic on femoral motion with stationary supra-lumbar vertebrae, the vertebrae of the harvested specimen was fixed with a stainless rod and both femurs fixed. Also, the AT and PT were analyzed during muscle asymmetric contraction in both femurs fixed. Also, the lateral tilt and axial rotation were observed during the AT and PT. The continuous pelvic motions were analyzed using a motion analysis program and motion capture cameras. There were differ ... 전체 초록 보기
