Proprioceptive Function in Children With Adolescent Idiopathic Scoliosis

Abstract
A disturbance of postural equilibrium may exist in idiopathic scoliosis. Proprioceptive function is one of the factors involved. A study of proprioception in patients with adolescent idiopathic scoliosis (AIS) was carried out. No difference was noted in joint position sense and in fine motor control between 24 scoliotics and matched controls taken from a group of 70 normal children of the same age group. Blindfold weight discrimination, a test of muscle spindle and tendon stretch receptor function, also showed no abnormality in scoliotic children. The Charpentier test, though to be a test of control of muscle spindle function, showed a tendency to an infantile response in patients with adolescent idiopathic scoliosis, while the control subjects showed a normal size-weight response. The muscle spindle system may be at fault in AIS and postural equilibrium reactions may be abnormal in this disease.
