Patients with hemispatial neglect are more prone to limb spasticity, but this does not prolong their hospital stay

Abstract: Study explored whether stroke patients who suffer from hemispatial neglect tend to stay in hospitals longer because they are prone to limb spasticity. Data were collected retrospectively from the medical records for 106 stroke patients admitted between 2008 and 2010 to the inpatient neurorehabilitation unit of a regional teaching hospital in the United Kingdom. The statistical coincidence of hemispatial neglect and spasticity, and the length of hospital stay were the main outcomes of interest. Chi-square analyses indicated that individuals with left neglect were nearly one third more likely to develop spasticity than those without neglect, while nearly one half of those with left-sided spasticity showed neglect. Individuals with neglect stayed in the hospital 45 days longer than those without neglect, but the presence or absence of spasticity did not affect length of stay. The authors conclude that although individuals with hemispatial neglect are especially prone to limb spasticity, it may be the presence of neglect rather than spasticity that keeps them in the hospital.
