摘要： 本文目的是提出拮抗收缩曲线（Co－Contraction Profile，CCP）的客观评价方法，并用来测量中风患者步行中作用于膝关节的主动肌和拮抗肌的拮抗收缩水平。应用表面肌电图记录9例正常人，6例痉挛性偏瘫患者的股四头肌和绳肌在步行中的肌电活动。结果显示，痉挛性偏瘫患者的CCP水平除在负重期与正常人的CCP达到同样的高峰水平外，在站立相的大部分时期及迈步相的后期均较正常人的CCP水平显著增高（P＜0．05）。这表明CCP评定方法客观，具有能够揭示拮抗收缩模式变异原因的显著特点，可作为痉挛治疗前后评价的一种方法。

Abstract: The purpose of this study was to propose a co-contraction profile(CCP)to assess co-con-traction of agonist and antagonist muscles about the knee in spastic hemiplegic gait.Surface EMG wasrecorded from quadriceps and hamstrings of 9 ablet-bodied subjects and 6 spastic hemiplegic subjects follow-ing stroke.Results showed that CCPs were high during weight bearing both in able-bodied subject walkingand in subjects with spastic hemiplegia. However, they were higher in most part of stance phase and lateswing phase in spastic hemiplegics compared to able-bodied subjects (P<0.05).The study concluded thatco-contraction profiles provide descriptive information on the sources of variation in co-contraction,particu-larly in co-contraction in assessment of spastic hemiparetic subjects following stroke.
