Diagnostic and management concordance between chiropractors and neurosurgeons for patients with low back pain
Full text linkAbstract
Low back pain is the leading contributor to disability worldwide and a major cause of primary care visits. Alternative models of care delivery drawing on musculoskeletal experts’ skills and knowledge have received increasing attention for their potential ability to improve timely access to appropriate healthcare for patients with musculoskeletal disorders. The aim of this study was to evaluate diagnostic and management concordance between chiropractors, known as musculoskeletal experts, and neurosurgeons for patients with low back pain. Before being seen by a neurosurgeon, 101 eligible participants (mean age: 60.32 years) were evaluated by a chiropractor. Overall diagnostic agreement between chiropractors and neurosurgeons was 74.7%, with a moderate inter-rater diagnosis agreement (κ = 0.51; 95%CI [0.35–0.68]). Chiropractors were significantly less likely to attribute a diagnosis of non-specific LBP to participants (31.6%) compared to neurosurgeons (43.2%) (p = 0.02), with an agreement proportion of 80.0%. Overall management agreement was 82.0%, indicating that chiropractors possess good skills in triaging patients with low back pain, which can optimize patient trajectories by accelerating management of non-surgical cases and reducing waiting lists for spine surgery consultations. Prospective studies are needed to evaluate the impact of a chiropractor-informed triage on clinical outcomes and healthcare utilization for patients with low back pain

Full text linkChanges in pregnancy-related hormones, neuromechanical adaptations and clinical pain status throughout pregnancy: A prospective cohort study
Full text linkAbstract
During pregnancy, increased hormonal levels contribute to ligament laxity of the pelvis and could predispose to lumbopelvic pain. The main objective of this study was to assess changes in pregnancy-related hormones, neuromechanical adaptations and clinical pain status throughout pregnancy. An exploratory objective was to examine the possible association between those variables. Twenty-eight pregnant women participated in the study. At each trimester, they provided a blood sample (to measure relaxin, estrogen and progesterone), completed questionnaires assessing clinical status (functional disability, risk of poor prognosis of prolonged lumbar disability, avoidance behaviors, anxiety and pain catastrophizing), and were asked to perform a flexion-relaxation task (erector spinae electromyography and trunk kinematics). Results showed that throughout pregnancy, nocturnal and diurnal lumbopelvic pain intensity and related-disability, risk of poor lumbopelvic pain prognosis as well as avoidance behaviors increased, while pain catastrophizing decreased. Neuromechanical characteristics of flexion-relaxation task, including low back muscle activity and trunk kinematics, were similar across the three trimesters. Positive correlations were found between disability and estrogen levels (changes between first and second trimester, p = 0.05), and estrogen and diurnal lumbopelvic pain intensity (change between second and third trimester, p = 0.02). A positive correlation was also found between weight and the Pelvic Girdle Questionnaire score (changes between second and third trimester, p = 0.05). Negative correlations were found between weight (change between first and second trimester) and lumbopelvic maximal angle (p = 0.003), FRP onset for pelvic (p = 0.04) and lumbopelvic (p = 0.003) angles as well as FRP cessation for lumbopelvic angle (p = 0.001). These results show that, in pregnant women, pain and disability are associated with hormonal changes rather than trunk neuromechanical characteristics during a flexion-relaxation task. These results suggest that the flexion-relaxation task may not be an appropriate proxy to study vertebral and pelvic muscle control in pregnant women
