title: [Range of motion of the scoliotic spine in adults].
abstract: OBJECTIVE
  To describe the movement of the trunk in adults with untreated adolescent idiopathic scoliosis (AIS) and to evaluate their relationship with the age of the patients, the location and angle of the curve, and the number of involved intervertebral segments.
  
  
  METHODS
  Two hundred adult subjects with untreated AIS, without associated signs, were analyzed with rachimetry. The flexion, extension, bending, and rotation of the trunk were determined for each patient. The results were compared with a different sample: healthy subjects without spinal disease/other groups with more severe scoliosis (treated).
  
  
  RESULTS
  In the absence of discopathy, regardless of the angle, location of the curve, or age of the patient, adults with untreated AIS demonstrated a 24% increase in truncal flexion, and a 30% decrease in hip flexion. The other movements studied with rachimetry were comparable to normal subjects. Lesions of the intervertebral segments increased in number and severity with age. These lesions progressively limited the mobility of the spine, initially in extension; and then in bending and flexion.
  
  
  CONCLUSIONS
  The measurement of the mobility of the spine and the pelvis is part of the systematic examination of patients with adult scoliosis. This information can be used to improve the patients' health and spinal function; independent of their age and degree of spinal deformity.
