髂腰肌对髋关节功能的实验性研究

由于髂腰肌在人体中所处位置、肌纤维走向、起止点位置关系等,具有特殊性和复杂性,目前尚无适宜方法获得在体运动过程中该肌工作可信的定量数据。结合下肢肌肉附着点三维坐标的研究提供的有关资料、数据,根据髋关节解剖位和运动全程幅度中肌长度、力臂的变化规律,对髂腰肌的功能进行定量分析和评定。结果表明,对下肢机械轴即髋膝关节中心连线作用而言,在解剖基准位,髂腰肌对髋关节有旋内功能。

Specialized Experiments to the Iliopsoas for the Function of the Hip

Because of its position in the body,muscle fiber alignment,the position relation of the origins and terminations etc.,the iliopsoas have its special with the complexity.Still now,we have no the feat method to acquire the authentic fixed amount data in exercise process for the muscle works.To conduct specialized quantitative analysis and assess of the iliopsoas function by combining data provided by the research for the three-dimentional coordinate of the origins and terminations of lower limb muscles and by according to the variety regulation of the muscle length and the arm of muscular force when the hip was at standard anatomic attitude and in the whole distance range with exercise.Result enunciation: In regard to the machine axes of lower extremity(hip and knee joint center on-line),at standard anatomic attitude,the iliopsoas have the function of inside-revolve to hip joint.
