Effects of intensive phonomotor treatment on reading in eight individuals with aphasia and phonological alexia.

PURPOSE: The aim of this study was to investigate effects of a multimodal treatment of phonology, phonomotor treatment, on the reading abilities of persons with aphasia (PWA) with phonological alexia. METHOD: In a retrospective, single-group design, this study presents pre-, post-, and 3-months posttreatment data for 8 PWA with phonological alexia. Participants completed 60 hr of phonomotor treatment over 6 weeks. Wilcoxon signed-ranks tests and group effect sizes comparing pre-, immediately post-, and 3-months posttreatment performance on tests of phonological processing and reading were performed. RESULTS: Group data showed phonological processing and oral reading of real words and nonwords improved significantly posttreatment; these gains were maintained 3 months later. No group improvement was found for reading comprehension; however, one individual did show improvement immediately post- and 3-months posttreatment. CONCLUSIONS: This study provides support that phonomotor treatment is a viable approach to improve phonological processing and oral reading for PWA with phonological alexia. The lack of improvement with comprehension is inconsistent with prior work using similar treatments (Conway et al., 1998; Kendall et al., 2003). However, this difference can, in part, be accounted for by differences in variables, such as treatment intensity and frequency, outcome measures, and alexia severity.

An analysis of aphasic naming errors as an indicator of improved linguistic processing following phonomotor treatment.

PURPOSE: The aim of this study was to investigate the influence of phonomotor treatment on the types of errors produced during a confrontation naming task for people with aphasia (PWA). METHOD: Ten PWA received 60 hr of phonomotor treatment across 6 weeks. Confrontation naming abilities were measured before and after treatment, and responses were coded as correct or incorrect. Incorrect responses were coded for error type. Paired t tests comparing pre-, post- and 3 months posttreatment naming accuracy and error type were performed. RESULTS: Group data showed that naming accuracy on trained items improved significantly immediately post treatment, and gains were maintained 3 months later. Naming accuracy on untrained items did not show significant improvement immediately post treatment or 3 months later. Results of error type analysis were not significant. However, a decrease in omission errors and an increase in mixed errors were noted immediately post treatment for naming of untrained items. CONCLUSION: Results suggest that intensive phonomotor treatment improved lexical-retrieval abilities and may have triggered a shift in linguistic processing, as indicated by a decrease in omission errors on trained items and an increase in mixed errors on untrained items.
