OBJECTIVE: To evaluate the efficacy of a functional restoration program for patients with chronic low back pain, using overall disability and work ability as the primary evaluation criteria. PATIENTS AND METHODS: We prospectively studied patients aged 18 years or older who had been on sick leave because of nonspecific low back pain for at least 3 months and whose job position was still open. The program was delivered on a day-hospital basis 5 days a week for 5 weeks. Patients were followed up for 1 year. RESULTS: We included 39 patients, 11 females and 28 males with a mean (± SD) age of 43 ± 8 years and a mean sick-leave duration of 10 ± 7 months. After 1 year, 26 (67%) patients reported improvements and 25 (64%) had returned to work. Compared to the year before the program, the number of sick leave days was decreased by 51% (120 ± 140 vs. 244 ± 114, P < 0.05). The work-and-leisure-activities subscore of the validated French version of the Dallas Pain Questionnaire (DRAD) was significantly improved (57 ± 24 vs. 70 ± 17 at baseline, P < 0.05). The patients still on sick leave after 1 year were older and had greater alterations in baseline DRAD subscores for anxiety/depression and daily activities, compared to the patients who had returned to work. CONCLUSIONS: Our functional restoration program was effective and allowed two-thirds of patients to resume work. Factors associated with failure to resume work were well-known correlates of chronicity. Our results support the use of functional restoration programs in patients with incapacitating low back pain. They suggest that functional restoration may deserve to be started earlier, after only 3 months with chronic pain, in patients who are unable to work.
