Effect of Combined Bee Venom Acupuncture and NSAID Treatment for Non-Specific Chronic Neck Pain: A Randomized, Assessor-Blinded, Pilot Clinical Trial

This study aimed to investigate the feasibility of a combined treatment of bee venom acupuncture (BVA) and non-steroidal anti-inflammatory drugs (NSAIDs) for the treatment of non-specific chronic neck pain (NCNP). Patients with NCNP for >= 3 months were randomly allocated to a BVA, NSAIDs, or combined group (1:1:1), receiving 6 sessions of BVA, loxoprofen (180 mg daily), or a combination, respectively, for 3 weeks. Recruitment, adherence, and completion rates were calculated to assess feasibility. Bothersomeness, pain, disability, quality of life, depressive status, treatment credibility, and adverse events were assessed. In total, 60 participants were enrolled, and 54 completed the trial. Recruitment, adherence, and completion rates were 100%, 95%, and 90%, respectively. Bothersomeness, pain, disability, and depressive symptoms significantly improved in all groups after treatment (p < 0.05). The combined group showed continuous improvement during the follow-up period (p < 0.05). Quality of life was significantly improved (p < 0.05), and treatment credibility was maintained in the BVA and combined groups. No serious adverse events were reported. Combined treatment of BVA and NSAIDs are feasible for the treatment of NCNP, showing high persistence of the effect, credibility, and safety. Additional trials with longer follow-up are needed to confirm this effect.
