Abstract: Objective
To determine the relationship between cognitive-perceptual function and functional independence in stroke patients. Method: Thirty-three patients (16 male, 17 female) with first ever ischemic stroke were enrolled. Their mean age was 60.4 years and the mean post-onset duration was 8.1 months. Subjects underwent detailed cognitive assessment including digit span test, line bisection test, Albert test, Wechsler nonverbal memory scale, Korean Hopkins verbal learning Test, Rey complex figure test, and trail making test A. Their functional outcomes were assessed using Functional Independence Measure (FIM) and Modified Barthel Index (MBI). Results: Among the cognitive subtests, Wechsler nonverbal memory scale, Albert test, and Rey complex figure test scores had significant correlation with both FIM and MBI scores. Patients with right hemispheric stroke showed significantly lower scores in line bisection test and Rey complex figure test than those with left hemispheric stroke patients. Conclusion: Visuospatial perception and nonverbal memory functions seemed to be two most important cognitive- perceptual domains for functional recovery of stroke patients.
