Sponsor decision: no sufficient patient

Monocentric, comparative, randomized, controlled interventionnal study in 2 parallel groups, aiming to compare the efficacy of the ATLAS device with that of a standard lumbar belt on the reduction of pain felt in patients with subacute or chronic low back pain with lumbar disc disease.

The main expected benefit is a reduction in pain experienced in patients with subacute or chronic low back pain during and after wear. Consequently, an improvement in the quality of daily life is expected with a less significant impact of low back pain.

The main objective of the study is to compare the efficacy of the ATLAS medical device with a standard lumbar support belt in terms of immediate reduction of low back pain experienced in patients with subacute or chronic low back pain.
