Chronic neck pain is a commonly experienced symptom that often influences work efficiency and life satisfaction for years. A total of 180 participants suffering mechanical chronic neck pain will be recruited and randomized into either electro-thumbtack needle therapy group or sham electro-thumbtack needle therapy group. All participants will receive the standardized neck exercise instruction at their first treatment session and will be asked to perform the exercise once every day during 4-week treatment. All assessments will be performed by the assessor and the assessment results will be all kept from the acupuncturist. The statistician will be involved in neither assessment nor treatment and will be blinded regarding intervention group code.
This prospective trial will be a single-center, participant-blinded, randomized controlled trial. It is reported in previous studies that both acupuncture and transcutaneous electrical nerve stimulation are effective in reducing neck pain comparing to placebo or exercise. Taking into account the convenience of electro-thumbtack needle therapy shown in clinical practice, this study aims to evaluate the efficacy and safety of electro-thumbtack needle therapy for alleviating chronic neck pain compared with sham electro-thumbtack needle therapy.
