Pure motor stroke/hemiparesis is the most common (33-50%) lacunar syndrome; the lacune is usually in the posterior limb of the internal capsule, which carries the descending corticospinal and corticobulbar tracts, or the basis pontis.
This syndrome consists of hemiparesis or hemiplegia that typically affects the face, arm, and leg equally. However, the face or leg can be involved to a lesser extent than other regions, and occasionally, only arm or leg weakness is noted by patients. Transient sensory symptoms (but not signs) may be present. Dysarthria and dysphagia may also be present.
Hemiparesis or hemiplegia is noted, with hyperreflexia and Babinski sign; no involvement of any other system is observed.
