[Scraping technique of stuck needle at Anmian point in the treatment of insomnia: a randomized controlled trial].

Objective: To compare the efficacy difference in the treatment of insomnia between scraping technique of stuck needle and conventional acupuncture at Anmian (Extra).

Methods: One hundred and thirty one cases were randomized into an Anmian group (68 cases) and a conventional acupuncture group (63 cases). In the Anmian group, Anmian (Extra) was selected. After arrival of qi, the stuck needling was adopted by rotating the needle gently in single direction, 2-3 rounds till the needle body was stuck tightly. Afterwards, the needle tail was touched gently with the index finger to fix the needle body and the needle handle was scraped gently with the thumbnail from bottom to up. The needle was retained for 30 min. In the conventional acupuncture group, Sanyinjiao (SP 6), Shenmen (HT 7) and Baihui (GV 20) were selected and stimulated with reducing technique by rotating the needles. The needles were retained for 30 min. The treatment was given once every day, continuously for 2 weeks in both groups. The score of each factor and the total score in Pittsburgh sleep quality index (PSQI) were assessed before and after treatment in the two groups. Additionally, the efficacies of two groups were evaluated.

Results: For the patients in the conventional acupuncture group, the sleep quality and time of falling into spleen after treatment were improved as compared with those before treatment (all P < 0.01). The improvement of sleep time, sleep efficiency, sleep disturbance, hypnotic drug and daytime dysfunction, and PSQI total score did not present statistically significant difference as compared with those before treatment (all P > 0.05). After treatment, for the patients in the Anmian group, the factor score and total score in PSQI were apparently improved as compared with those before treatment (P < 0.01, P < 0.05). And the improvements of the above items were superior to the conventional acupuncture group (P < 0.01, P < 0.05). The total effective rate was 91.2% (62/68) in the Anmian group and was 74.6% (47/63) in the conventional acupuncture group. The clinical efficacy in the Anmian group was apparently superior to the conventional acupuncture group.

Conclusion: The scraping technique of stuck needle at Anmian (Extra) achieves the superior effect on insomnia as compared with the conventional acupuncture.
