Low back pain is pain affecting the lumbar segment of the spine. It is characterized depending on its origin and its duration. In this study, only common subacute or chronic low back pain, i.e. with a mechanical origin, is studied [1]. One of the treatments suggested is the use of a lumbar orthotic device. However, few studies exist so as to clearly elucidate the mechanism of action of these devices. In our study, a single type of lumbar orthotic, used in the treatment of common subacute or chronic low back pain was analyzed using a numerical model: lumbar support belts. The objective is to perform an overall study elucidating how belts work, in order to determine main parameters influencing on the treatment of low back pain using a FE trunk model. The studied parameters will be related to the patient's morphology, the belt and the mechanical characteristics of the human trunk.
