[Effectiveness and compliance to a center-based short rehabilitation program with a home-based program for chronic low back pain].

OBJECTIVES
To assess the effectiveness and compliance to a short center-based intensive rehabilitation program followed by a home-based program for chronic low back pain.


METHODS
Open prospective study in patients with chronic low back pain. The program included five weekly meetings of 12 day. Followed by a home-based program consigned on a booklet. Evaluation of deficiencies (lumbar and radicular pains on an analog visual scale, Schöber Mac Rae test, distance finger-ground, Shirado test, Sorensen test), disabilities (Quebec functional index), and handicap (analog visual scale) were assessed at J0, five weeks, three months and one year. Compliance was assessed quantitatively (a number of exercises, duration of the meetings, numbers meetings per week) and qualitatively (semi-quantitative ordinal scale). Patient's global opinion on the effectiveness of the program was collected on a semi-quantitative ordinal scale.


RESULTS
60 patients (20 women), aged of 45 +/- 10,4 years, were included. Duration of the symptoms was 110 +/- 123 months. At five weeks, a significant improvement of all parameters was observed. This improvement was maintained at three months. At 12 months, there was no more significant improvement. Compliance to the program was 64,4%. 40.7% of the patient did not realize their exercises correctly. The majority gave up back muscle isometric reinforcement exercises. Score of Shirado test, Quebec index and EVA handicap were significantly different in the group realizing the home-base program. At one year, 79% of the patients regarded this program as useful.


CONCLUSION
Although quantitative compliance with the home-based program can be considered as satisfactory, the effectiveness of this intensive rehabilitation program of lumbar decrease after three months. This can be explained by a fast deterioration of qualitative compliance. The effectiveness of a short supervised program between 3 and 6 months associated a more powerful message of motivation must be evaluated.
