Electro-thumbtack Needle Therapy for Chronic Neck Pain

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.
