Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study the investigators are examining the effectiveness of two different speech therapy protocols for word retrieval impairments experienced by individuals with stroke-induced aphasia. One treatment involves errorless naming treatment and the other employs verbal plus gestural facilitation of word retrieval. Participants will receive one of the two treatments over several months. Before and after treatment the investigators will administer several tests and conversational samples to examine changes associated with the treatments. The investigators hypothesize that, whereas both treatments will lead to improvements in words rehearsed in therapy, communication outcomes in conversation will be broader for the verbal plus gestural protocol.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Errorless Naming Treatment

Group Type EXPERIMENTAL

Word Retrieval Treatments for Aphasia

Intervention Type BEHAVIORAL

Speech therapy sessions take place 4 times per week for up to 90 minutes per session. Following a phase of baseline pre-testing, two phases of speech therapy will take place lasting up to 20 sessions per phase. Post-testing will take place immediately upon completion of the treatment phases and again at 1 month post study completion.

Verbal+Gestural Facilitation

Group Type EXPERIMENTAL

Word Retrieval Treatments for Aphasia

Intervention Type BEHAVIORAL

Speech therapy sessions take place 4 times per week for up to 90 minutes per session. Following a phase of baseline pre-testing, two phases of speech therapy will take place lasting up to 20 sessions per phase. Post-testing will take place immediately upon completion of the treatment phases and again at 1 month post study completion.
