Résumé :

Lateral bending test is a common evaluation of AIS patients prior to their surgical correction. Traditionally this evaluation is made by the assessment of the curve's flexibility from side-bending radiographs. As a complement to this static test, dynamic bending was experimented while simultaneously quantifying muscular and kinematic behavior of the spine. The biggest contribution to total EMG output was 36% from lumbar muscles in healthy and 35% from abdominal muscles in scoliotic subjects. Continuous measuring of kinematics and muscle activation patterns throughout lateral bending could be an evaluation tool for distinguishing pathological from normal behavior.
