The short- and long-term effect of osteopathic manipulative treatment on pain, and psychosocial factors in adults with chronic low back pain.

CONTEXT: Chronic low back pain (CLBP) has long plagued mankind, but little progress has been made in finding a rational and effective treatment, let alone a common cause. This study is an attempt to fill that void by measuring short- and long-term effects of osteopathic manipulative treatment (OMT), including psychosocial and pain reduction in CLBP patients.

OBJECTIVES: The objectives of this study were to investigate the effectiveness of neuromusculoskeletal medicine/osteopathic manipulative medicine (OMM) in treating CLBP, with a focus on biopsychosocial (pain sensitivity questionnaire [PSQ]) and pain control in chronic conditions.

METHODS: The study involved a large, single cohort observational design of 101 patients. The inclusion criteria for selecting patients targeted those with "nonspecific" CLBP. The National Institutes of Health (NIH) Minimum Dataset for Chronic Low Back Pain (NMD) was the measurement tool and was administered at consent (baseline), 2, 4, and 8 weeks and at 6 and 12 months. Time trends were analyzed as overall mean. Pairwise differences were compared between time points. Mixed-effects models were utilized to test the association of time with pain and biopsychosocial scores.

RESULTS: Pain and PSQ scores decreased over the study timeline. The most significant change for both pain and biopsychosocial scores occurred at 6 months compared to baseline, with a further reduction at 12 months.

CONCLUSIONS: OMT has been demonstrated to significantly reduce pain and psychosocial factors related to CLBP in both the short and long term.
