Patients with amyotrophic lateral sclerosis made stereotyped 20.degree. elbow flexion movements as rapidly as possible while surface EMG (electromyography) was recorded from biceps and triceps. The characteristic ballistic movement EMG pattern could be recognized in almost all the patients. The 1st agonist burst and the 1st antagonist burst, which are normally limited in duration, were prolonged in patients with clinical signs of pyramidal tract disease or .alpha.-motor neuron disease or both. Prolongation of these components permits the muscles to generate sufficient forces to accomplish the movements.
