This study compared the effect phonological treatment (PCA) paired with Intensive Speech Therapy (IST) versus semantic treatment (SFA) paired with IST had on improvements in Chronic Post-Stroke Aphasia (CPSA).
Six participants received phonological treatment paired with IST and six participants received semantic treatment paired with IST for 6-15 hours for 120 or 240 hours total. Treatment was either in-office or via teletherapy. The phonological treatment focused on retraining the participants the sounds that letters make and the semantic treatment focused on describing the attributes of nouns.
Group analyses showed significant differences in the PCA group’s scores for Letter Sound, Spoken Letter Sound, Syllable Length Reading, and Letter Length Spelling which were all trained tasks and significant differences in the SFA group’s scores for Commands, Repetition, and Spoken Letter which were all untrained tasks. These findings illustrate that phonological treatment improves an individual with aphasia’s ability to read and write single words. In addition, individuals who received phonological treatment were able to maintain their improvements overall. Individuals who received the phonological treatment also made improvements in self-cueing which was not assessed in testing.
