ABSTRACT
BACKGROUND: Individuals with chronic low back pain (cLBP) may benefit from multimodal functional restoration programs (FRPs). OBJECTIVE: The aim of this study was to analyze characteristics of individuals with cLBP who were referred or not to an FRP. Because cLBP is a bio-psycho-social disorder, medical and social parameters were analysed. METHODS: This was an observational cross-sectional study performed in 2017 in 6 tertiary centres in France. Consecutive individuals with cLBP visiting a rheumatologist or physical medicine and rehabilitation physician were included. Individuals referred or not to an FRP were compared by demographic characteristics, duration of sick leave over the past year, self-reported physical activity>1h/week, pain (numeric rating scale 0-10), anxiety/depression (Hospital Anxiety and Depression Scale), disability (Oswestry Disability Index) and kinesiophobia (Tampa Kinesiophobia Scale). Univariate and multivariate logistic regression analyses were performed, estimating odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: We included 147 individuals with cLBP. The mean (SD) age was 49 (12) years and 88 (60%) were women; 58 (38%) were referred to an FRP. On multivariate analysis, referral to an FRP was associated with reduced pain level (OR: 0.95, 95% CI: 0.91-0.99, for each 1-point increase in pain score), self-reported lack of physical activity (OR: 0.84, 95% CI: 0.72-0.98) and longer sick leave (OR: 1.03, 95% CI: 1.01-1.05, for 30 more days of sick leave). CONCLUSION: In this multicentric observational study, referral to an FRP was linked to pain, self-reported physical activity and sick leave but not medical characteristics assessed. These findings confirm the bio-psycho-social approach of FRPs for cLBP.
