OBJECTIVES:   The purpose of this study was to investigate recurrence rate and prognostic factors in a large population of patients with low back pain (LBP) up to 1 year after chiropractic care using standardized definitions.

METHODS:   In Switzerland, 722 patients with LBP (375 male; mean age = 44.5 ± 13.8 years) completed the Numeric Rating Scale for pain (NRS) and the Oswestry Disability Index (ODI) before treatment and 1, 3, 6, and 12 months later (ODI up to 3 months). Based on NRS values, patients were categorized as “fast recovery,” “slow recovery,” “recurrent,” “chronic,” and “others.” In multivariable logistic regression models, age, sex, work status, duration of complaint (subacute: ≥14 days to <3 months; chronic: ≥3 months), previous episodes, baseline NRS, and baseline ODI were investigated as predictors.

RESULTS:   Based on NRS values, 13.4% of the patients were categorized as recurrent. The recurrent pattern significantly differed from fast recovery in duration of complaint (subacute: odds ratio [OR] = 3.3; chronic: OR = 10.1). The recurrent and chronic pattern significantly differed in duration of complaint (chronic: OR = 0.14) and baseline NRS (OR = 0.75).
