This article critically analyzes the literature pertaining to the interand intraobserver reproducibility of spinal palpation to investigate the consistency of study results and assess the level of evidence for reproducibility.

Mid-back pain (MBP) is one of these symptoms. The incidence and prognosis of different traffic injuries and their related conditions (e.g. neck pain, low back pain, depression or others) has been investigated previously; however, knowledge about traffic collision-related MBP is lacking. The study objectives were to describe the incidence, course of recovery and prognosis of MBP after traffic collisions, in terms of global self-reported recovery. Longitudinal data from a population-based inception cohort of all traffic injuries occurring in Saskatchewan, Canada, during a 2-year period were used. Annual overall and age-sex-specific incidence rates were calculated, the course of recovery was described using the Kaplan-Meier technique, and associations between participant characteristics and time-to-self-reported recovery were explored in 3496 MBP cases using Cox prop...

However, there is now a small group of chiropractors with clinical research training that are shifting their focus away from traditional research pursuits towards new and innovative areas. Specifically, these researchers are now delving into areas such as brain injury, work disability prevention, undifferentiated chest pain, hip osteoarthritis, and prevention of pain in children and adolescents to name a few. In this paper, we highlight recent research in these new areas and discuss how clinical research efforts in musculoskeletal areas beyond the spine can benefit patient care and the future of the chiropractic profession.

The aims of this study are 1) to describe the baseline clinical characteristics and prevalence of myocardial perfusion (MP) deficits, by use of an adenosine stress SPECT MPI, in NSCP patients without known CAD discharged after hospitalization for suspected ACS; and 2) to prospectively describe the 4-year clinical outcome in terms of all-cause and cardiac mortality; hospitalization and coronary revascularization procedures; and cardio-vascular events in patients with and without MP deficits. We evaluated a series of 272 consecutive patients with acute NSCP and aged 18-75years. ICD10-based registries were used to determine the primary outcome (a composite measure of incident CAD death, ACS, or revascularization) and two secondary outcomes (1. all-cause death; 2. a composite measure of ca...

The objectives of this study were (1) to determine inter-observer reliability of the diagnosis 'musculoskeletal chest pain' in patients with acute chest pain of non-cardiac origin using a standardized examination protocol, (2) to determine inter-observer reliability of single components of the protocol, and (3) to determine the effect of observer experience. Eighty patients were recruited from an emergency cardiology department. Patients were eligible if an obvious cardiac or non-cardiac diagnosis could not be established at the cardiology department. Four observers (two chiropractors and two chiropractic students) performed general health and manual examination of the spine and chest wall. Percentage agreement, Cohen's Kappa and ICC were calculated for observer pairs (chiropractors and students) and all. Musculoskeletal chest pain was diagnosed in 45 percent of patients. Inter-observer kappa values were substantial for the chiropractors and overall (0.73 and 0.62, respectively), and moderate for the students (0.47). For single items of the protocol, the overall kappa ranged from 0.01 to 0.59. Provided adequate training of observers, the examination protocol can be used in carefully selected patients in clinical settings and should be included in pre-and post-graduate clinical training.

Methods: Consecutive patients with noncardiac chest pain (n = 302) recruited from an emergency cardiology department were assessed. Using data from self-report questionnaires, interviews, and clinical assessment, patient characteristics were associated with the MSCP diagnosis, and the decision-making process of the clinician was reconstructed using recursive procedures in the tradition of constructing Classification and Regression Trees. Results: Thirty-eight percent of patients had MSCP. There was no single determinant that predicted the condition completely. However, many items with high associations could be identified, mainly with high negative predictive value. The decision-making process was reconstructed giving rise to a 5-step, linear decision tree without branches. Conclusions: Clinicians use a combination of indicators including systematic palpation of the spine and chest wall and items from the case history to diagnose MSCP. However, the high negative predictive values of the main determinants suggest that the MSCP diagnosis may be a diagnosis by exclusion. (J Manipulative Physiol Ther 2012;35:184-195)

Results indicated a positive effect in favor of the chiropractic treatment after 4 and 12 weeks. The current article investigates the hypothesis that the advantage observed at 4 and 12 weeks would be sustained after 1 year. In addition, we describe self-reported consequences of acute musculoskeletal chest pain at 1-year follow-up. Methods: In a nonblinded, randomized controlled trial undertaken at an emergency cardiology department and 4 outpatient chiropractic clinics, 115 consecutive patients with acute chest pain of musculoskeletal origin were included. After the baseline evaluation, patients were randomized to 4 weeks of either chiropractic treatment or selfmanagement, with posttreatment questionnaire follow-up 52 weeks later. The primary outcome measures were change in pain intensity (11-point box numerical rating scale) and self-perceived change in pain (7-point ordinal scale). Results: Both groups experienced decreases in pain, positive global, self-perceived treatment effect, and increases in the 36-Item Short Form Health Survey scores. No statistically significant differences were observed between groups at the 1-year follow-up, and we could not deduce a common trend in favor of either intervention. Conclusions: At the 1-year follow-up, we found no difference between groups in terms of pain intensity and self-perceived change in chest pain in the first randomized clinical trial assessing chiropractic treatment vs minimal intervention for patients with acute musculoskeletal chest pain. Further research into health care utilization and use of prescriptive medication is warranted. (J Manipulative Physiol Ther 2012;35:254-262)

Active approaches are directed towards diagnosis and treatment of potentially life threatening conditions, especially acute coronary syndrome/ischemic heart disease. However, according to the literature, chest pain may also be due to a variety of extra-cardiac disorders including dysfunction of muscles and joints of the chest wall or the cervical and thoracic part of the spine. The diagnostic approaches and treatment options for this group of patients are scarce and formal clinical studies addressing the effect of various treatments are lacking.
