In people with acute stroke and hemiparesis, the disorder is present in 10.4% of patients. Rehabilitation may take longer in patients that display<unk>  behaviour. The Copenhagen Stroke Study found that patients that presented with ipsilateral pushing used 3.6 weeks more to reach the same functional outcome level on the Barthel Index, than did patients without ipsilateral pushing. Pushing behavior has shown that perception of body posture in relation to gravity is altered. Patients experience their body as oriented "upright" when the body is actually tilted to the side of the brain lesion. In addition, patients seem to show no disturbed processing of visual and vestibular inputs when determining subjective visual vertical. In sitting, the push presents as a strong lateral lean toward the affected side and in standing, creates a highly unstable situation as the patient is unable to support their body weight on the weakened lower extremity. The increased risk of falls must be addressed with therapy to correct their altered perception of vertical.<unk>  is sometimes confused with and used interchangeably as the term hemispatial neglect, and some previous theories suggest that neglect leads to<unk> . However, another study had observed that<unk>  is also present in patients with left hemisphere lesions, leading to aphasia, providing a stark contrast to what was previously believed regarding hemispatial neglect, which mostly occurs with a right hemisphere lesion. Karnath summarizes these two conflicting views, as they conclude that both neglect and aphasia are highly correlated with<unk>  possibly due to the close proximity of relevant brain structures associated with these two respective syndromes. However, the article goes on to state that it is imperative to note that both neglect and aphasia are not the underlying causes of<unk> .
