基于本体感觉调控系统探讨“腰背委中求”论治慢性腰痛的作用机理

"腰背委中求"理论是针灸治疗的四总穴歌理论之一，被广泛应用于慢性腰痛治疗，临床研究证实委中穴针刺可显著减轻慢性腰痛患者疼痛症状，改善生活工作能力。最新研究表明，本体感觉调控系统在维持腰椎功能，降低腰痛复发起着重要的作用，其系统调控功能的下降与腰痛的发生有密切相关。前期研究表明针刺委中穴可以改善患者疼痛，并提升本体感觉运动觉的调控功能，本体感觉调控系统可能是电针委中穴治疗起效的关键靶点,但两者之间是否有着内在联系尚不清楚。本研究拟用针刺委中穴治疗慢性腰痛患者，观察其症状、体征与生活能力的改善情况，检测腰椎肌力、腰椎空间恢复能力（位置觉）、腰椎运动控制能力（运动觉）、姿势控制能力等本体感觉调控指标的改变情况，从而探讨针刺委中穴治疗慢性腰痛的起效机制。本研究有助于从本体感觉调控系统角度阐述"腰背委中求"论治腰痛的科学内涵，为腰痛病的临床治疗与研究提供理论与技术依据。

"Treating lumbar-back problems by stimulating Weizhong " theory is the acupuncture treatment four total hole one of the theories, which has been widely used in chronic back pain treatment, clinical studies confirmed the bilateral point acupuncture can significantly reduce chronic back pain patients pain symptoms, improve the ability to work life.

The research shows that needling weizhong hole could improve patients' pain, and ascend body feel sense of movement control function, the body feeling control system may be acusector weizhong hole treatment take effect of the key targets, but whether to have the inner link between them is still not clear. This study to treat patients with chronic low back pain with acupuncture Weizhong Point, to observe the improving situation of symptoms, signs, and life skills .Also to detect the changing situation of lumbar muscle strength, lumbar space recovery capabilities (position sense), the lumbar motion control capacity (kinesthesia) posturethe ability to control and proprioception regulation indicators.So as to explore acupuncture Weizhong Point treatment of chronic low back pain onset mechanism. This study helps to elaborate scientific connotation of "Treating lumbar-back problems by stimulating Weizhong" theory ,and provide theoretical and technical basis for the clinical treatment of low back painand research of low back pain disease ,from the the proprioceptive regulation system angle.
