Tabled values represent means with SDs in parentheses.
↵F2-a The Western Aphasia Battery (WAB) (Kertesz, 1982) was used to derive the aphasia quotient and assess spontaneous speech, auditory comprehension, and repetition. The maximum score was 20 for spontaneous speech, 80 for auditory comprehension, 100 for repetition, and 100 for the aphasia quotient. Data were missing on five right control subjects.
↵F2-b Block Design subtest scaled scores from the WAIS-R (Wechsler, 1981).
↵F2-c Grip strength is expressed as a standardized T-score. Data were missing on five right control subjects.
↵F2-d Two-point discrimination was tested on the index finger of each hand. Data were missing on five right control subjects and six RHD patients with contralateral somatosensory deficits that were too severe to measure using this task.
*A t test or Mann–Whitney U test showed that the left hemisphere stroke group was impaired (p < 0.05) relative to the left control group.
**A t test or Mann–Whitney U test showed that the right hemisphere stroke group was impaired (p < 0.05) relative to the right control group.
