Objectives Previous reports established the feasibility of a telehealth model for delivering speech–language therapy via Internet videoconferencing, which connects individuals with primary progressive aphasia (PPA) to an expert speech and language pathologist for treatment. This study reports feasibility of the same telehealth intervention in a larger set of progressive aphasia participants and explores factors potentially influencing functional intervention outcomes. Methods Participants with PPA or progressive aphasia in the context of a neurodegenerative dementia syndrome and their communication partners were enrolled into an 8-session intervention, with 3 evaluations (baseline, 2 months, and 6 months postenrollment). Half of the participants were randomized into a "check-in" group and received 3-monthly half-hour sessions postintervention. Mixed linear models with post hoc testing and percent change in area under the curve were used to examine communication confidence over time, as well as the influence of check-in sessions and the role of communication partner engagement on communication confidence. Results Communication confidence improved at the 2-month evaluation and showed no significant decline at the 6-month evaluation. Item-level analysis revealed gains in communication confidence across multiple communication contexts. Gains and maintenance of communication confidence were only present for the engaged communication partner group and were not bolstered by randomization to the check-in group. Discussion Internet-based, person-centered interventions demonstrate promise as a model for delivering speech–language therapy to individuals living with PPA. Maintenance is possible for at least 6 months postenrollment and is better for those with engaged communication partners, which supports the use of dyadic interventions. [ABSTRACT FROM AUTHOR]

Purpose: The use of telepractice in the field of communication disorders offers an opportunity to provide care for those with primary progressive aphasia (PPA). The Western Aphasia Battery–Revised (WAB-R) is used for differential diagnosis, to assess severity of aphasia, and to identify a language profile of strengths and challenges. Telehealth administration of the WAB-R is supported for those with chronic aphasia due to stroke but has not yet been systematically explored in neurodegenerative dementia syndromes. To fill this gap, in-person and telehealth performance on the WAB-R from participants with mild to moderate PPA was compared. Method: Nineteen participants with mild to moderate PPA were administered the WAB-R in person and over videoconferencing. Videoconferencing administration included modifications to the testing protocol to ensure smooth completion of the assessment. Subtest and Aphasia Quotient (WAB-AQ) summary scores were compared using concordance coefficients to measure the relationship between the administration modes. Results: In-person and telehealth scores showed strong concordance for the WAB-AQ, Auditory Verbal Comprehension subtest, and Naming & Word Finding subtest. The Spontaneous Speech test summary score had slightly lower concordance, indicating the need for caution when comparing these scores across administration modes. Conclusion: These findings support extending the use of telehealth administration of the WAB-R via videoconferencing to those with mild to moderate PPA given appropriate modifications to testing protocol.
