Conditions
Brief summary
This study investigates the degree and pattern of language rcovery in English and Mandarin Singaporeans with aphasia following stroke. It also aims to investigate the factors that influence the degree of language impairment and recovery. In order to assess for aphasia and its severity, we need to validate the locally developed Singapore Aphasia Test with the local population.
Interventions
The Singapore Aphasia test (SGAT) is a locally developed diagnostic assessment of language function. It has an English and a Mandarin verson. The English SGAT comprises 45 subtests while the Mandarin SGAT comprises 47 subtests. The number of subtests is higher in the Mandarin SGAT as it includes two further subtests namly the Tone perception and Tone production subtests. Together, the subtests evaluate language performance across the following areas: spontaneous speech, recall/memory, perception

The number of subtests is higher in the Mandarin SGAT as it includes two further subtests namly the Tone perception and Tone production subtests. Together, the subtests evaluate language performance across the following areas: spontaneous speech, recall/memory, perception skills, auditory comprehension, verbal expression, reading comprehension and written expression. Participant responses will be administered one-on-one by speech-language therapists who are proficient in English and Mandarin. Test performance will be scored on-line and will be video-recorded for reliability analysis. In cases where the participant is bilingual in English and Mandarin, both language versions of the SGAT will be administered. For such cases, the two tests will be administered with an interval of two weeks between testing. Language testing is expected to last approximately 1-2hours. SGAT will be re-administered after 6 months .
