title: Arthrogryposis multiplex congenita: perinatal and electromyographic findings, disability, and psychosocial outcome.
abstract: Fifty-two patients with arthrogryposis multiplex congenita were followed up for 1 to 36 years. There were six twin pregnancies, and delivery was complicated by breech position in 16 cases. In 19 cases the cause was atrophy of the alpha motoneurons of the spinal cord, detected by electromyography. Six patients did not achieve walking ability. Severe disability for other reasons was noted in two patients who had bilateral rigid extension contractures of the elbows and in six patients whose spinal deformities interfered with the balance of the trunk. Treatment of flexion contractures of the hips and knees seemed to be important in case it promotes the walking ability. Spinal deformities interfering with the balance of the trunk should be treated operatively. Restoration of elbow flexion was the main goal in operative treatment of the upper extremities. The intelligence of the patients was slightly above normal. The psychological analysis revealed significant diverging features compared with average population in testing situation. Socially the patients seemed to cope well.
