Exercise-based treatment is part of the recommendations for good practice in the treatment of low back pain (acute, sub-acute and chronic).~The low back pain population is heterogeneous. This heterogeneity would cause the positive effects of a treatment to be canceled out by the negative effects of another part of the population.~This polymorphism has led several authors to classify low back pain into subgroups. These subgroups constitute more homogeneous clinical pictures and would facilitate the adaptation of treatments.~The recommendations of the American Physical Therapy Association suggest 5 subgroups of low back pain. One of them is low back pain with movement control impairment. In this subgroup, Luomajoki studied the reliability of different functional tests used in clinical practice. 6 out of 10 motion control fault tests show good reliability.~The quantified analysis of the movement of low back pain patients would make it possible to determine the sensitivity of detecting an anomaly in the 6 lumbar movement control tests.~LoBaCoM is a monocentric, exploratory prospective study.~The purpose is to define a kinematic (angular) threshold corresponding to an anomaly detected clinically by three therapists for each test.
