The Application of Lexical Retrieval Training in Tablet-Based Speech-Language Intervention

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Speech-Language Pathology

Background:

• Shortened hospitalizations and social isolation necessitate innovative rehabilitative care.
• Aphasia, a post-stroke language disorder, often requires targeted therapy for lexical retrieval.
• Technology offers a viable platform for delivering rehabilitative interventions.

Purpose of the Study:

• To explore the efficacy of a tablet-based therapy application for individuals with aphasia.
• To compare autonomous engagement versus systematic encouragement in aphasia telerehabilitation.
• To analyze behavioral patterns and outcomes associated with different therapy approaches.

Main Methods:

• Pilot evaluation involving six individuals with aphasia using a tablet-based lexical retrieval application.
• Two conditions: autonomous engagement and systematic encouragement for effortful word retrieval.
• Analysis of response latency, cue use, task accuracy, and standardized cognitive-linguistic assessments.

Main Results:

• Participants receiving systematic training used fewer cues and spent more time on tasks.
• Systematic training correlated with increased independent engagement with therapy.
• Improved outcomes on standardized assessments were observed in the systematically trained group.

Conclusions:

• Tablet-based rehabilitation is a feasible approach for aphasia telerehabilitation.
• Systematic encouragement may enhance engagement and outcomes in aphasia therapy.
• Technology can support best-practice recommendations for post-stroke language recovery.
