Utilization of chiropractic services in patients with osteoarthritis and spine pain at a publicly funded healthcare facility in Canada: A retrospective study.

Abstract

Osteoarthritis (OA) is one of the most prevalent and disabling musculoskeletal diseases worldwide. There is preliminary evidence from experimental studies and consensus documents that chiropractic management may alleviate spine and/or extremity OA related pain in the short term. This research explores the potential relationship of a pragmatic course of care, including soft tissue therapy, spinal manipulation, and other treatments commonly delivered by chiropractors, to spine and extremity pain in patients with OA. A retrospective analysis of prospectively collected data from the chiropractic program at a publicly funded healthcare facility was conducted. The primary outcome measures for patients diagnosed with spine and/or extremity OA (n= 76) were numeric pain scores of each spinal and extremity region at baseline and discharge, and a change score was determined. Statistically significant improvements that exceed a clinically meaningful difference in pain numeric rating scale scores were demonstrated by point change reductions from baseline to discharge visits. Change scores exceeding a minimally clinically important difference of "2-points" were present in the sacroiliac (-2.91), extremity (-2.84), cervical (-2.73), thoracic (-2.61), and lumbar (-2.59) regions. Patients diagnosed with OA in a socioeconomically disadvantaged community demonstrated reductions in mean pain scores in both a clinically meaningful and statistically significant manner concurrent with a course of chiropractic care.
