Evaluating Adaptive Scheduling in Computer-Based Naming Therapy for Aphasia After Stroke

What this Trial Is About

Researchers are studying aphasia, a language disorder caused by stroke and other brain injuries that affects over two million people in the United States. This research focuses on improving treatments for anomia, a word-finding difficulty that is a major frustration for people with aphasia. The study aims to evaluate new approaches to naming treatment that enhance long-term retention and help patients use their naming skills in daily life. This sub-study is part of a larger project and specifically investigates the benefits of adaptive trial scheduling. Participants will take part in a randomized crossover study comparing three treatment conditions an adaptive spacing condition, a high-item non-adaptive spacing condition, and a low-item non-adaptive spacing condition. Each participant will receive all three conditions in a random order. Treatment involves computer-based training sessions lasting 30 minutes, four times per week for ten weeks per condition. During sessions, participants practice naming pictured objects using flashcards and rate their own accuracy. Responses and accuracy are recorded, and participants can replay and repeat answers if needed. All sessions, assessments, and probes are conducted via telehealth. Participants will undergo baseline assessments, treatment sessions, and follow-up probes at 1 week, 3 months, and 6 months after treatment. There are typically 3-4 but up to 6 assessment sessions and around 120 one-on-one treatment sessions per participant over approximately one year to 18 months. The primary outcomes measured are changes in correct naming of treated and untreated pictured objects and generalization to everyday contexts. Secondary outcomes include language use in discourse, communication abilities, and motivation. The study is sponsored by the University of Pittsburgh and involves detailed monitoring through telehealth technology.
