Relationship between Physical Activity and Pain in U.S. Adults.

PURPOSE: We sought to assess the relationship between physical activity (PA) and pain within the available sample, with secondary aims to assess prevalence of pain, PA levels, health care seeking behaviors, and impact of pain on daily activities and work. METHODS: We conducted an epidemiological cross-sectional observational study utilizing National Health Interview Survey data from 2020. We examined the self-reported adherence to current PA guidelines and the prevalence of pain. We hypothesized those dealing with pain were less likely to meet PA guidelines. The PA levels, pain prevalence, frequency, and intensity were assessed via the survey and relationships explored via modeling. RESULTS: Of 31,568, 46% were men and 53.99% women with mean age of 52.27 yr (±17.31 yr). There were 12,429 (39.37%) participants that reported pain on some days, 2761 (8.75%) on most days, and 4661 (14.76%) every day. The odds of engaging in PA decreased in a stepwise fashion based on frequency and intensity of pain reporting when compared with no pain. Importantly, PA is a significant correlate affecting pain reporting, with individuals engaging in PA (strength and aerobic) demonstrating two times lower odds of reporting pain when compared with those not meeting the PA guidelines. CONCLUSIONS: There is a significant correlation between meeting PA guidelines and pain. Meeting both criteria of PA guidelines resulted in lower odds of reporting pain. In addition, the odds of participating in PA decreased based on pain frequency reporting. These are important findings for clinicians, highlighting the need for assessing PA not only for those dealing with pain but also as a potential risk factor for minimizing development of chronic pain.

Use of Manual Therapy for Posterior Pelvic Girdle Pain.

Use of manual therapies in the treatment of posterior pelvic pain is a common practice. The rationale for use of manual therapies is often associated with the structural movement of the sacroiliac joint. Increasing evidence has shown this not to be the case, as manual therapy's effect is more neurophysiological in nature. This article seeks to clarify the difference between the two explanations as well as to expand upon outside influences such as expectations, therapeutic alliance, and equipoise that may influence the outcome of treatment. Treatment effects may be maximized with manual therapy if clinicians have an understanding of the role of each of these variables in their treatment approach.

The Value of Electrodiagnostic Studies in Predicting Treatment Outcomes for Patients with Spine Pathologies.

The utility of electrodiagnostic testing for spine pathologies varies based on the underlying suspected pathology. This article reviews the data on electrodiagnostic testing for common spine pathologies, with a specific focus on the prognostic data with regard to treatment outcomes. This information is placed into context of diagnostic confidence, which is derived from the combination of disease prevalence and the sensitivity and specificity of a test.
