- Digital speech therapy was found to be noninferior to conventional workbook-based therapy for improving speech intelligibility in poststroke dysarthria patients.
- The study was a single-blind, randomized controlled noninferiority trial with 73 participants in South Korea, using a smartphone-based app or workbook therapy for 4 weeks.
- Speech intelligibility scores improved in both groups, with an adjusted between-group difference of 4.49 (95% CI 0.61-8.37), supporting noninferiority with a margin of 19 points.
- No significant differences were observed in secondary outcomes related to speech function or psychological status, and no treatment-related adverse events occurred.
- The digital therapy showed high usability (score 89.6) and adherence of 64.6%, but efficacy in older patients with cognitive deficits or those unable to use smartphones is still unknown.
