Abstract:
[Objective] The purpose of this study was to compare the effectiveness of acupuncture and local injection for neck pain.
[Methods] A randomized controlled clinical trial was conducted in which 33 patients with neck pain were randomly allocated to either an acupuncture group or a local injection group. For the acupuncture group (n=16), a stainless steel needle was inserted to a depth of 10 to 20 mm and manually stimulated (sparrow pecking method) for 20 seconds. A 25 gauge needle was inserted to a depth of 10 to 20 mm and neovitacain (dibucaine hydrochloride 0.1%, sodium salicylate 0.3%, calcium bromide 0.2%) and neurotropin (non protein component extracted from the skin of rabbits treated with vaccinia virus) were injected for the local injection groups (n=17). Both groups received each treatment at the most painful points weekly for four weeks. Primary outcome measurement was intensity of the pain evaluated with a visual analogue scale (VAS). Secondary outcomes were the Neck Disability Index (NDI) and a standardized questionnaire of cervical root disease (developed by Tanaka et al. at Tohoku Univ.). The evaluations were independent from the therapists.
[Results] The acupuncture groups showed better results in all the outcome measurements than those in the local injection group for the effect immediately after the treatment, the effect of sequential treatment and the continuing effect after completion of treatment.
[Discussion] The result of this study suggested that acupuncture can be a useful treatment method compared with local injection. The difference in the effects between the two treatment methods may be due to the difference in the mechanism to suppress pain.
