Brief summary
The study aims to examine the efficacy and safety of sinew acupuncture for chronic mechanical neck pain (CMNP).
Detailed description
Objectives: Sinew acupuncture is a superficial needling technique with the advantage of minimal pain, feasible manipulation, and no apparent adverse effects. The proposal aims to examine the efficacy and safety of sinew acupuncture for chronic mechanical neck pain (CMNP). Hypothesis to be tested: Sinew acupuncture can reduce pain intensity, and improve neck pain disability and health-related quality of life without significant side effects for CMNP subjects compared to a sham acupuncture treatment. Design: A randomized, subject- and assessor-blind, sham acupuncture-controlled clinical trial Participants: Subjects (N=130) will be randomized into sinew acupuncture or sham acupuncture group (in 1:1 ratio). Study instrument: Visual Analog Scale (VAS), Northwick Park Neck Pain Questionnaire (NPQ) and Short Form-36 (SF-36) Intervention: Sinew acupuncture group will receive five sessions of needling in two weeks. Sham group will receive the non-invasive treatment with the same procedures. All subjects are followed up for 4 weeks. Main outcome measures: VAS for neck pain intensity at week 3 serves as the primary outcome. VAS at other time points, NPQ score and SF-36 at week 1, 2, 3, and 6, and adverse events are analyzed as the secondary outcomes. Data analysis: Analysis will be on the 'intention to treat' principle. T-test and mixed-effect model analysis will be used to measure primary and secondary outcomes respectively. Expected results: Five sessions of sinew acupuncture treatment can significantly reduce neck pain intensity, and improve neck pain disability and quality of life without obvious side effects.
Interventions
DEVICESinew acupuncture
The subject is asked to be on sitting posture. The skin around the needling points is disinfected with a 75% alcohol swap. A tube-guided, sterilized, disposal needle is then inserted (at a small angle to the skin) into the acupoint at 0.5-1 cun (depending on point location and body size of the subject). No needle sensation (deqi sensation) is required. A piece of surgical adhesive tape will be applied to the needle immediately after insertion.
DEVICESham acupuncture
The procedure in the sham acupuncture group will be as similar to that of the acupuncture group as possible. In the sham acupuncture group, however, a mock plastic needle guiding tube is tapped on the surface of each acupoint (Ashi point and traditional acupoints) to produce some discernible sensation. A piece of adhesive tape is immediately applied to fix the needle on the dermal surface tapped, without needle insertion. In addition, a plastic tube-guided needle is superficially inserted at the sham point at less than 5mm in depth.
