目的评价针灸治疗与颌肌肌筋膜痛相关的症状的疗效。方法将28例年龄在18岁以上的慢性颌肌肌筋膜痛患者随机分为真针刺组(n=16)和假针刺组(n=12)。治疗前，每个受试者都要咬紧牙关2分钟。针刺或假针刺合谷大肠四号穴15min。真正的针灸是通过穴位处的粘性泡沫垫穿透针头进行的。假针灸是通过刺伤皮肤进行的，不穿透，用一根短而钝的针灸针穿过放置在穴位以外的泡沫垫。在治疗前和治疗后用数字评分表进行头颈疼痛综合评分。治疗前后给予咬肌机械性疼痛刺激，并在视觉模拟评分中评定疼痛耐受性水平。进行配对t检验以检测疼痛程度的显著变化。结果接受真正针灸治疗的受试者的颌痛(P=0.04)、颌面紧绷(P=0.04)和颈部疼痛(P=0.04)显著减轻，咬肌的疼痛耐受性显著提高(P=.001)。受试者无法确定他们接受的是真针灸还是假针灸(P=0.69)。假针刺组没有观察到明显的疼痛减轻。结论：与假针刺相比，单次针刺合谷大肠4穴可显着减少大部分肌筋膜痛点。
AIMS To evaluate the effectiveness of acupuncture in treating symptoms associated with myofascial pain of the jaw muscles. METHODS Twenty-eight subjects over the age of 18 and diagnosed with chronic myofascial pain of the jaw muscles were randomized to receive real (n = 16) or sham (n = 12) acupuncture. Prior to treatment, each subject clenched his or her teeth for 2 minutes. Acupuncture or sham acupuncture was then administered at the Hegu large intestine 4 (LI4) acupoint for 15 minutes. Real acupuncture was given by penetrating the needle through a sticky foam pad at the acupoint. Sham acupuncture was conducted by pricking the skin, without penetration, with a shortened, blunted acupuncture needle through a foam pad placed away from the acupoint. General head and neck pain ratings were obtained before and after treatment on a numerical rating scale. A mechanical pain stimulus on the masseter muscle was given before and after treatment and rated on a visual analog scale to measure pain tolerance level. Paired t tests were performed to detect significant changes in pain levels. RESULTS Subjects receiving real acupuncture experienced a significant reduction in jaw pain (P = .04), jaw/face tightness (P = .04), and neck pain (P = .04), and a significant increase in pain tolerance of the masseter muscle (P = .001). Subjects were not able to determine whether they received real or sham acupuncture (P = .69). No significant pain reductions were observed in the sham acupuncture group. CONCLUSION A single acupuncture session using one acupoint at Hegu large intestine 4 significantly reduced most myofascial pain endpoints when compared to sham acupuncture.
