OBJECTIVE: To investigate the relationship between severity of unilateral spatial neglect (USN) and functional recovery in activities of daily living after a right-hemisphere stroke. DESIGN: Observational study. SETTING: Rehabilitation hospital in Italy. PARTICIPANTS: We investigated 107 of 131 inpatients with right-hemisphere stroke who were consecutively admitted to our rehabilitation hospital. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: To assess USN severity, conventional and nonconventional Behavioral Inattention Tests (BITs) were performed at admission to inpatient rehabilitation at a median of 19 days after stroke occurrence. FIM was performed both on admission to and discharge from inpatient rehabilitation to assess functional autonomy. FIM efficiency (improvement of FIM score per day of stay length) and FIM effectiveness (proportion of potential improvement achieved) were calculated. RESULTS: Fifty-four (50.5%) of the 107 patients were affected by USN. In these 54 patients, both conventional and nonconventional BIT scores were significantly correlated with FIM scores assessed at discharge from rehabilitation: ρ values were .385 (P=.004) and .396 (P=.003), respectively. After adjustment for 7 potential confounders, including FIM scores before rehabilitation, we found a significant positive association between either conventional or nonconventional BIT scores and FIM scores after rehabilitation (r=.276, P=.047 and r=.296, P=.033, respectively), FIM efficiency (r=.315, P=.022 and r=.307, P=.025, respectively), and FIM effectiveness (r=.371, P=.006 and r=.306, P=.026, respectively). CONCLUSIONS: Data support the independent prognostic role of USN severity assessed at admission to inpatient rehabilitation after a right-hemisphere stroke. Models aimed at predicting the functional outcome in stroke survivors may benefit from inclusion of USN severity.
