The purpose of the investigation was to study the effect of acupuncture on myogenic headache and to examine whether electromyographic recordings of jaw muscle activity would provide objective evidence of the effect of such treatment. In 21 dental students, 14 males and seven females, with a history of 2--10 years of headache, acupuncture was performed unilaterally in the foot between the 4th and 5th metatarsal bones (G 41). The needle was inserted to a depth of 10--15 mm and moved continuously by hand for 15--20 min. Electromyographic recordings of postural activity in the right and left anterior temporal and masseter muscles were obtained in the same sitting before, during and after acupuncture treatment. In clinical controls 24 h, 1 month and 4 months after the treatment, 12 subjects reported considerable improvement, two variable results, and seven no change. The electromyographic recordings showed an average decrease in postural activity during acupuncture, particularly of the temporalis muscles, and a further decrease after completed treatment. However, marked individual variations in muscular response were noted. The results indicate that acupuncture treatment can relieve headache, and that electromyographic recordings may provide objective evidence of the effect of acupuncture.
该研究的目的是探讨针刺对肌源性头痛的影响，并检验下颌肌肉活动的肌电图记录是否能为这种治疗效果提供客观证据。在21名牙科学生中，14名男性和7名女性，有2至10年的头痛病史，在第四和第五跖骨之间的足部进行单侧针刺（G 41）。针插入深度为10至15毫米，手动持续移动15至20分钟。在针刺治疗前、治疗期间和治疗后，于同一次就诊时获取左右颞肌前部和咬肌姿势活动的肌电图记录。在临床对照中，治疗后24小时、1个月和4个月，12名受试者报告有显著改善，2名结果不一，7名无变化。肌电图记录显示针刺期间姿势活动平均减少，尤其是颞肌，治疗结束后进一步减少。然而，注意到肌肉反应存在明显的个体差异。结果表明针刺治疗可缓解头痛，且肌电图记录可为针刺效果提供客观证据。
