Every year, more than 100,000 Americans acquire aphasia, a condition in which a person has difficulty speaking or writing—or understanding spoken or written information. ASHA members play a key role in screening for, assessing, and treating this population as well as educating the public on prevention methods.
The Clinical Aphasiology Conference (CAC) gives experts an opportunity to gather and share their latest discoveries in the clinical treatment of aphasia. Guest Editor Michael de Riesthal has developed a special issue of the American Journal of Speech-Language Pathology (AJSLP) featuring 14 articles based on research presented at the 51st CAC. Check out highlights from the special issue below!
The issue opens with an article by Raymer and Roitsch using systematic reviews and meta-analyses to show the effectiveness of constraint-induced language therapy for aphasia. Later, King et al. compare the effects of two treatment protocols for acquired apraxia of speech: Sound Production Treatment and Metrical Pacing Therapy.
Hinckley and Sanchez studied how speech-language pathologists (SLPs) determine which aphasia treatment to use. Repetition priming has led to improved naming ability in anomia; Silkes investigated whether this correlation was the result of deeper-level semantic processing or simply learned correspondences between words and pictures. Elsewhere in the special issue, Fisher and colleagues showed that an objective clustering method could be used to determine verb fluency performance in individuals with Alzheimer’s dementia.
Telehealth in Aphasia
Three articles focused on remote treatment for aphasia. Dunne and colleagues studied whether the changes in language impairment and quality of life associated with group conversation treatment could be replicated in a virtual group.
Kallhoff et al. showed that Combined Aphasia and Apraxia of Speech Treatment (CAAST) could be administered remotely. Later, Kallhoff and another team of co-authors compared sound production treatment delivered remotely and in person.
More Highlights From the CAC
Park and colleagues examined verb production of people with nonfluent aphasia, finding that although some verb usage was preserved, people with nonfluent aphasia used fewer verbs that have less specific meanings—verbs such as “do” or “make.” Scadden Nelson et al. later found that people with aphasia were more affected by background noise when completing a story retell task.
Slow speech rate and abnormal prosody are used to differentiate aphasia from apraxia of speech; Haley and colleagues provide SLPs with an appropriate word syllable duration cutoff to help with assessments. Then, Azios et al. advocated for the use of conversational analysis to study texting exchanges in people with aphasia.
Elsewhere, Harmon and colleagues sought to determine a link between (a) physiological attentiveness and arousal and (b) word retrieval, showing that helping these patients fully engage during therapy can result in more positive outcomes. MacWhinney and Fromm described the collaborative commentary system, a feature that allows researchers, instructors, students, and clinicians to comment on the TalkBank clinical databases, including AphasiaBank.
