Background and purpose

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.

Methods and results

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

The musculoskeletal system is recognized as a possible source of pain in patients with chest pain. The objectives of the present study were (1) to investigate the interobserver reliability of an overall diagnosis of musculoskeletal chest pain using a standardized examination protocol in a cohort of patients with chest pain suspected to be of non-cardiac origin, (2) to investigate the interobserver reliability of the single components of the protocol, and finally, (3) to investigate the importance of clinical experience on the level of interobserver reliability.

Methods and results

Eighty patients with acute chest pain were recruited from a cardiology department. Four observers (two chiropractors and two chiropractic students) performed a physical examination and an extended manual examination of the spine and chest wall. Percentage agreement, Cohen's Kappa and ICC were calculated for observer pairs and overall. Musculoskeletal chest pain was diagnosed in 44.0 % of patients. Interobserver kappa values were substantial for the chiropractors and overall, and moderate for the students. For single items of the protocol, both pairs showed fair to substantial agreement regarding pain provocation tests and poor to fair agreement regarding spinal segmental dysfunction tests.
