Descrizione dettagliata
This study is a prospective, multicenter, randomized, evaluator-blinded confirmatory clinical trial designed to evaluate the efficacy and safety of LEXURE, a digital therapeutic for language in patients with post-stroke aphasia.
Eligible participants who provide informed consent will undergo screening and be randomized in a 1:1 ratio to either the LEXURE group or the control group.
LEXURE Group:
Participants assigned to the LEXURE group will receive structured digital language training using the LEXURE application. The training consists of multiple language tasks and will be performed for approximately 30 minutes per session, 5 times per week, for 10 weeks.
Control Group:
Participants assigned to the control group will perform structured language training using a workbook-based intervention. The training will consist of predefined language tasks and will be conducted for approximately 30 minutes per session, 5 times per week, for 10 weeks.
The primary efficacy endpoint will be assessed using the K-WAB/PK-WAB-R, and evaluations will be conducted by an independent, evaluator-blinded assessor.
