THE CONTROL OF TONUS AFTER INJURIES TO THE BRAIN OR SPINAL CORD OF MAN

Abstract

Injuries to the central nervous system of man often produce marked abnormalities of tone in the striated musculature of the body. The specific changes after lesions in certain definite portions such as the spinal cord or cerebellum have been discussed. Two common abnormalities, showing as prominent symptoms increased tonus, hemiplegia and Parkinson''s disease, were analyzed from the viewpoints of recent studies of the physiology of tone, and possible treatment is suggested.
