The musculoskeletal system is a common, but often overlooked, cause of chest pain. Little is known about the efficacy of spinal manipulation for this condition. The purpose of the present study is to evaluate the relative effectiveness of two conservative treatment approaches for acute musculoskeletal chest pain, 1) a spinal manipulation-based therapy as a typical example of chiropractic treatment and 2) self-management as an example of minimal intervention. In a non-blinded, randomised controlled trial set at an emergency cardiology department and four outpatient chiropractic clinics, 115 consecutive patients with acute chest pain and no clear medical diagnosis at initial presentation were included. After a baseline evaluation, patients with musculoskeletal chest pain were randomized to four weeks of chiropractic treatment or self-management, with post-treatment questionnaire follow-up four and 12 weeks later. Primary outcome measures were numeric change in pain intensity (11-point box numerical rating scale) and self-perceived change in pain (7-point ordinal scale). Secondary measures included Medical Outcomes Study Short Form 36 (SF-36) scores, change in pain intensity (chest, thoracic spine, neck and shoulder/arm), and self-perceived change in general health. Preliminary results will be available at the time of presentation.Background and purpose
