Abstract
The duration of action potentials of motor units (MU) of the gastrocnemius and tibialis muscles was studied in patients with spinal cord trauma by the method of local electromyography. The duration of action potentials of gastrocnemius MU was found to be reduced on average by 27%, and of tibialis MU by 38% of the age norm. The degree of shortening of the action potentials of the gastrocnemius and tibialis MU was not directly dependent on the level of spinal cord injury, the length of time after trauma, or the severity of the spastic syndrome. Changes in the duration of action potentials of MU are evidently due to differences in the degree of atrophy developing as a result of prolonged adynamia.
