Objective:
To evaluate relationships between unilateral spatial neglect and both overall and cognitive-communicative functional outcomes in patients with right hemisphere stroke.
Design:
Assessment of overall and cognitive-communicative function was conducted on admission to acute rehabilitation, at discharge, and at 3-month follow-up.
Setting:
Urban, acute inpatient rehabilitation facility.
Patients:
Fifty-two consecutive admissions of adult right-handed patients with a single, right hemispheric stroke, confirmed by computed tomography scan.
Main Outcome Measures:
The FIM instrument and reading comprehension and written expression items of the Rehabilitation Institute of Chicago Functional Assessment Scale(R).
Results:
Patients made significant functional gains between admission and discharge, and between discharge and follow-up on the FIM. Severity of neglect was correlated with total, motor, and cognitive FIM scores at admission, discharge, and follow-up. Subjects with neglect had significantly more days from onset to admission and a longer length of rehabilitation stay than subjects without neglect. FIM outcomes were significantly different for subject groups with more severe neglect. Both the presence of neglect and its severity were significantly related to functional outcomes for reading and writing.
Conclusions:
Patients with neglect show reduced overall and cognitive-communicative functional performance and outcome than patients without neglect. Further studies are needed to explore causal relationships between these factors.
