Self-rehabilitation At Home After LumbaR Arthrodesis (SAHARA)

Due to population aging, lumbar arthrodesis is becoming more frequent in general population. At the same time, those patients need early rehabilitation, even if they do not experiment any motor disability after surgery : it has been showed that early rehabilitation improves lumbar pain thanks to muscle strengthening. The design of the study is prospective,monocentric, controlled and randomized. This study compares progressive self-rehabilitation at home after lumbar arthrodesis, explained to the patient by a physiotherapist during his or her stay at the hospital and started right after surgery, versus rehabilitation done by a physiotherapist 4 to 6 weeks after surgery (standard treatment). The primary outcome is decrease of lumbar pain at 6 weeks and 3 months after surgery. The secondary outcomes are improvement of functional abilities and improvement of pelvis and limbs ranges of motion. Patients of both groups will be followed by surgeon and physiotherapist at 6 weeks and 3 months.
