Comparative effectiveness and economic evaluation of Chuna manual therapy for chronic neck pain: protocol for a multicenter randomized controlled trial

摘要

Neck pain is a highly prevalent medical?condition that incurs substantial social burden. Although manual therapy is widely used for treatment of neck pain, the body of evidence supporting its effectiveness and safety is not conclusive. The aim of this study is to examine the effect, safety, and cost-effectiveness of Chuna manual therapy, a?traditional Korean manual therapy?for treatment of various musculoskeletal complaints. This study is the protocol for a two-armed parallel, assessor-blinded, multicenter, randomized controlled trial. A total 108 patients with chronic neck pain (time to onset ≥?3?months, numeric rating scale [NRS] of neck pain ≥?5) will be recruited at five Korean medicine hospital sites. Participants will be allotted to one of two groups (n?=?54, respectively): the Chuna manual therapy group, and the?usual care (conventional physical therapy and medication treatment) group. Ten sessions of Chuna manual therapy or usual care will be administered twice a week for five weeks. Since the study design does not permit patient or physician blinding, the outcome assessor and statistician will be blinded. The?primary outcome will be the visual analogue scale (VAS) of neck pain at 5 weeks?after randomization. Secondary outcomes include?the VAS of radiating arm pain, NRS of neck pain and radiating arm pain, Vernon-Mior neck disability index (NDI), Northwick Park neck pain questionnaire (NPQ), EuroQol-5 Dimension (EQ-5D), EQ-VAS, patient global impression of change (PGIC), economic evaluation, adverse effects, and drug consumption. Follow-up outcome assessments will be conducted at 3, 6, 9, and 12?months after randomization. This study will evaluate the comparative effectiveness of Chuna manual therapy and usual care on chronic neck pain. Adverse events, and costs and effectiveness (utility) data will be evaluated to assess safety and exploratory cost-effectiveness (economic evaluation). This study aims to provide evidence on the effectiveness, safety, and cost-effectiveness of Chuna manual therapy. Clinical Research Information Service (CRIS), KCT0002732 .
