[Effect of acupuncture at Jiaji on F-wave and clinical efficacy in stroke patients with upper limb spasticity on the hemiplegic side].

OBJECTIVES: To observe the effect and clinical efficacy of acupuncture at Jiaji (EX-B2) on F-wave latency and amplitude in stroke patients with hemiplegic upper limb spasticity. METHODS: A total of seventy-six patients with hemiplegia after stroke were randomly and equally divided into an observation group (38 cases, 3 cases dropped off) and a control group (38 cases, 2 cases dropped off). The both groups received basic medical treatment, acupuncture at Jianyu(LI15), Quchi (LI11), Huantiao (GB30), Yanglingquan (GB34) and rehabilitation training. The observation group received acupuncture at Jiaji point (C4 to T5) on the hemiplegic side. The treatment lasted 30 min per session, once daily, 5 times a week for 4 weeks. The F-wave latency and amplitude of the median nerve on the affected side were measured, and scores of the modified Ashworth scale (MAS) and the Fugl-Meyer assessment-upper extremity (FMA-UE) were evaluated before treatment and after 4 weeks of treatment. RESULTS: <0.01). CONCLUSIONS: Acupuncture at Jiaji can inhibit the excitability of motor nerves, reduce muscle tension, alleviate spasticity, and enhance motor function recovery in patients with upper limb spasticity after stroke hemiplegia, thereby improving their quality of life.
