Abstract
• Kinesiologic analysis of the gaits of 21 autistic, 15 normal, and five hyperactive-aggressive children revealed that the autistic patients had (a) reduced stride lengths, (b) increased stance times, (c) increased hip flexion at "toe-off," and (d) decreased knee extension and ankle dorsiflexion at ground contact. In many respects, the gait differences between the autistic and normal subjects resembled differences between the gaits of parkinsonian patients and of normal adults. These preliminary results are compatible with the view that the autistic syndrome may be associated with specific dysfunction of the motor system affecting, among other structures, the basal ganglia.
