Stroke patients who cannot maintain a balanced sitting or standing position fall toward one specific side. There can be a strong tendency to actively use non-hemiplegic extremities to push the body away from the sound side. As well, patients may resist any attempt to correct their postures and finally fall toward the hemiplegic side. This falling asymmetry phenomenon has been termed ”Pusher syndrome.” The syndrome often occurs coincident with frequent lapses in consciousness, poor motor control, impaired sensory status, spatial neglect, and limited perceptual function. Recent observations have indicated that Pusher syndrome is strongly related to body orientation deficit and the presence of a lesion of the crus of the internal capsule. The factors and mechanisms related to Pusher syndrome will be substantiated in this paper through the review of pertinent articles.
