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

Abstract

BACKGROUND: 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. OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
