Does Patient Body Mass Index Affect the Outcome of Multimodal Rehabilitation in Chronic Mechanical Low Back Pain?

Study Design. Retrospective. Objective. The aim of this study was to investigate the effect of body mass index (BMI) on pain and disability in patients with chronic mechanical low back pain (LBP) treated with multimodal rehabilitation. Summary of Background Data. Despite being a well-known risk factor for developing LBP, there is minimal data on the effect of BMI on pain and disability in patients with chronic mechanical low back pain (LBP) treated with multimodal rehabilitation. Methods. Data from patients with chronic mechanical LBP who underwent multimodal rehabilitation treatment at a chain of spine rehabilitation outpatient clinics in one of the three BMI groups—1564 patients in normal body weight (BMI ≥18.5–24.9), 1990 patients in overweight (BMI ≥25–29.9), and 891 patients in obese (BMI ≥ 30) groups—were retrospectively analyzed. Pre- and post-treatment Numerical Pain Rating Scale (NPRS) and Oswestry Disability Index (ODI) scores, and final treatment outcomes were compared between the three groups. Multivariate analysis was used to determine the association between pre-treatment covariates and post-treatment clinical outcomes. Results. Post-treatment, the mean NPRS (P = 0.005) and mean ODI (P
