A controlled study on the outcome of inpatient and outpatient treatment of low back pain. Part I. Pain, disability, compliance, and reported treatment benefits three months after treatment

Outcome of inpatient and outpatient treatment of low back pain was studied in 459 patients (aged 35-54 years, 63% men); 156 inpatients, 150 outpatients and 153 controls. Changes in low back pain and in disability caused by it, and adherence and accomplishment of back exercises were used as short-term outcome criteria. The overall results showed a significant decrease in pain and disability and better compliance in the two treated groups when compared to the controls. There was also a significant difference in treatment gains between the inpatients and outpatients; i.e. the decrease in pain was greater and the frequency of back exercises higher in the inpatients. The inpatients also estimated their treatment benefits more positively than the outpatients.
