Identification of Risk Factors for Recurrence of Low Back Pain and Occupational Repercussions

Study Overview
=================
Brief Summary
-----------------
Low back pain (LBP) is the leading cause of disability and one of the most common reasons for physician visits in primary care, with a 33 % rate of recurrence during the first year, converting LBP into a chronic condition. The french High healthy authority recommend early occupational oriented intervention associated with a multidisciplinary rehabilitation program. However even if these recommendations are taken into appropriate account, risk for recurrence of Low back pain and occupational repercussions often occured. This study aims to identify the risk factor(s) of sick leave after a rehabilitation stay in outpatients and thus adapt cares provided to the patients in respect of their needs and expectations.
