Motor impersistence: a right-hemisphere syndrome. Kertesz, A., Nicholson, I., Cancelliere, A., Kassa, K., & Black, S. Neurology, 35(5):662–666, 1985. doi abstract bibtex We studied motor impersistence with a standardized clinical test of sustained actions, both in patients with acute focal stroke lesions, who were matched for age and size of lesion, and normal controls. Patients with right-sided lesions had significantly more impersistence than did those with left-sided lesions. The most discriminating tests were eye-closure, mouth-opening, tongue-protrusion, and gaze to the left. Right central and frontal lesions seemed to be more responsible for motor impersistence than were posterior or left-sided lesions. Although motor impersistence is sometimes seen with diffuse cerebral disease, it is also a sign of right-hemisphere lesions; the phenomenon is probably related to mechanisms of directed attention that are necessary to sustain motor activity.
