局部颤搐反应(LTR)是拍击相应节段骨骼肌上的触发点所诱发的骨骼肌紧张带的短促收缩,是肌筋膜疼痛综合征的临床客观测量指标。临床上,触发点是沿骨骼肌紧张带的最敏感触及点。LTR通常由机械刺激诱发,如拍击、针刺触发点。当拍击触发点诱发LTR时,能记录到一阵短暂的肌电活动。以往对缺血情况下人体指总伸肌的研究表明,中枢和局部的通道都参与了LTR的传导。在本研究中,1例23岁男性患者,6个月前发生车祸,肌电图、神经传
The local twitch response (LTR) is a short-term contraction of the skeletal muscle tension induced by striking the trigger point on the corresponding segmental skeletal muscle and is a clinical objective measure of myofascial pain syndrome. Clinically, the trigger point is the most sensitive touch point along the skeletal muscle tone. LTR is usually induced by mechanical stimulation, such as slapstick, acupuncture trigger point. When the trigger firing point triggered LTR, can record a brief episode of myoelectrical activity. Previous studies of human total extensor muscle under ischemic conditions showed that both central and local channels are involved in the conduction of LTR. In this study, a 23-year-old man with a car accident, electromyography, neuropathy
