OBJECTIVETo compare the difference in the efficacy on spasmodic torticollis between matrix needling technique combined with puncturing "Wuxin points" and the local injection of botox type A.

METHODSForty-two cases were randomized into an acupuncture group and a botox group, 21 cases in each one. In the acupuncture group, the matrix needling technique was used and acupuncture was adopted at Fengchi (GB 20), "Wuxin points" [Shuigou (GV 26), bilateral Laogong (PC 8) and bilateral Yongquan (KI 1)] and local Ashi points. In the botox group, botox type A was injected at several spots of local region. The treatment course was 1 month in the two groups. The efficacy in each weekend and the results of follow-up visit in half a year after treatment were compared between the two groups.

RESULTSIn the 1st weekend, the markedly effective rate was 42.8% (9/21) and the total effective rate was 90.5% (19/21) in the botox group, which were better than those of 4.8% (1/21) and 28.6% (6/21) respectively in the acupuncture group (both P < 0.01). In the 2nd weekend, the markedly effective rate was 71.4% (15/21) and the total effective rate was 95.2% (20/21) in the botox group, which were better than those of 19.1% (4/21) and 61.9% (13/21) respectively in the acupuncture group (both P < 0.01). In the 3rd weekend, the markedly effective rate was 66.7% (14/21) and the total effective rate was 95.2% (20/21) in the botox group, which were better than those of 38.1% (8/21) and 71.4% (15/21) respectively in the acupuncture group (both P < 0.05). The markedly effective rate and the total effective rate were not different significantly between the two groups in the treatment of 1 month and the follow-up visit in half a year (all P > 0.05). There was no adverse reaction in the acupuncture group. There were 14 cases of adverse reactions in the botox group, in which 9 cases of neck muscular weakness and 5 cases of neck muscular pain.

CONCLUSIONThe treatment of matrix needling technique and combined with acupuncture at "Wuxin points" achieves the significant efficacy on spasmodic torticollis. Although the effect is not obtained as quickly as the local injection of botox, the efficacy of matrix needling technique is similar to that of botox in the treatment of 1 month and the follow-up visit in half a year. Moreover, this therapy has no adverse reaction.
