[Guasha-fangsha therapy combined with electroacupuncture in treatment of greater occipital neuralgia: a randomized controlled trial].

ABSTRACT

OBJECTIVE: To observe the clinical effect of guasha-fangsha (scrapping and bleeding) therapy combined with electroacupuncture (EA) on greater occipital neuralgia. METHODS: Ninety patients with greater occipital neuralgia were randomly divided into an observation group (45 cases) and a control group (45 cases, 2 cases dropped out). In the control group, EA was delivered at Fengfu (GV 16) and bilateral Tianzhu (BL 10), Fengchi (GB 20), Wangu (GB 12), Yuzhen (BL 9) and Houxi (SI 3), with disperse-dense wave, at 2 Hz/100 Hz in frequency and 2 mA to 6 mA in intensity, for 30 min in each intervention, once every other days, 3 times a week. In the observation group, on the basis of the intervention as the control group, guasha-fangsha therapy was used along the distribution of the bladder meridian of foot-taiyang on the occipital region and that of the gallbladder meridian of foot-shaoyang on the lateral side of the head, once weekly. The duration of treatment was 3 weeks in the two groups. In the two groups, before treatment, after 1, 2 and 3 weeks of treatment and in follow-up visit after 3 weeks of treatment completion, the score of visual analogue scale (VAS) was observed; before and after treatment, as well as in follow-up visit after 3 weeks of treatment completion, the scores of self-rating anxiety scale (SAS), self-rating depression scale (SDS) and 36-item short-form health survey (SF-36) were observed; after treatment and in follow-up visit after 3 weeks of treatment completion, the clinical efficacy was evaluated. RESULTS: After one week of treatment, the VAS score in the observation group decreased when compared with that before treatment (P<0.05), while the scores in 2 and 3 weeks of treatment and in follow-up visit after 3 weeks of treatment completion were lower than those before treatment in the two groups (P<0.05) separately. At each time point after treatment, the VAS scores in the observation group were lower than those in the control group (P<0.05). After treatment and during the follow-up visit, the scores of SAS and SDS decreased when compared with those before treatment in the two groups (P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05); the scores of each item in SF-36 were elevated in comparison with those before treatment in the two groups (P<0.05), and the scores in the observation group were higher than those in the control group (P<0.05). After treatment, the total effective rate of the observation group was 91.1% (41/45), higher than that (76.7%, 33/43) of the control group (P<0.05). In follow-up visit, the total effective rate of the observation group was 91.1% (41/45), which was higher than 72.1% (31/43) of the control group (P<0.05). CONCLUSION: Guasha-fangsha therapy combined with electroacupuncture can effectively relieve greater occipital neuralgia, alleviate pain severity, ameliorate anxiety and depression and improve the quality of life in the patients.
