[Effect of pelvic member abduction on the kinematics of the thoracic and lumbar spine].
The motion of thoracic and lumbar spine segments has been analysed by mean of the skin landmarks method on 14 volunteers (7 males, 7 females). Results demonstrate that: There is no significant difference between male and female. There is either facilitation, or limitation of the motion of the characteristic landmarks of the spinal segments during trunk motion in perpendicular planes. The mobility of the spinal segments is associated with pelvic girdle motion in order to obtain the planed amplitude, and varies with hips abduction. The analysis of the precise mechanisms of relaxing or stretching of the pelvi-spinal musculo-ligamentous structures constitutes a large field of investigation that necessitates the study of other pelvic limbs postures and needs the use of robotic techniques.
