本文研究的目的是证实从人体膝关节副韧带和关节囊内的机械感受器到膝部相关肌群的反射弧的存在,并且确定在膝内翻或外翻时作为膝关节的稳定成分的相关肌群能否被该类反射弧选择性地激活。 11位受试者(9男2女)均来自学校,年龄24～47岁,无膝关节病史。测试中,受试者仰卧于检查台上,股四头肌和腘绳肌预收缩到一定肌电水平, The purpose of this study is to confirm the existence of reflex arcs from the human knee ligament and the mechanoreceptors in the capsular bag to the knee-related muscle groups and to determine the associated muscles that are the stabilizing components of the knee joint when the knee is valgus or valgus Whether a group can be selectively activated by such a reflex arc. Eleven subjects (9 males and 2 females) were all from school, aged 24-47 years with no history of knee joint disease. Test, the subjects sit on the examination table, quadriceps and hamstrings precontracted to a certain level of electromyography,
