Semantic deficits, deficits in word meaning, have a large impact on aphasic patients' verbal communication. We investigated the effects of semantic treatment on verbal communication in a randomized controlled trial. Methods-Fifty-eight patients with a combined semantic and phonological deficit were randomized to receive either semantic treatment or the control treatment focused on word sound (phonology). Fifty-five patients completed pretreatment and posttreatment assessment of verbal communication (Amsterdam Nijmegen Everyday Language Test [ANELT]). In an on-treatment analysis (n=46), treatment-specific effects on semantic and phonological measures were explored. Results-Both groups improved on the ANELT, with no difference between groups in overall score (difference, -1.1; 95% confidence interval [CI], -5.3 to 3.1). After semantic treatment, patients improved on a semantic measure ( mean improvement, 2.9; 95% CI, 1.2 to 4.6), whereas after phonological treatment, patients improved on phonological measures (mean improvement, 3.0; 95% CI, 1.4 to 4.7, and 3.0; 95% CI, 1.2 to 4.7). Conclusions-No differences in primary outcome were noted between the 2 treatments. Our findings challenge the current notion that semantic treatment is more effective than phonological treatment for patients with a combined semantic and phonological deficit.
The selective gains on the semantic and phonological measures suggest that improved verbal communication was achieved in a different way for each treatment group.
