Summary

This study evaluates the efficacy of smartphone-based speech therapy administered at home compared with usual care. Participants will be randomized into the treatment and waitlist control groups with an allocation ratio of 1:1.

Detailed description

Despite the importance of dysarthria intervention in post-stroke rehabilitation, further research in this area remains underexplored. This study builds on previous research on the use of smartphone-based dysarthria interventions based on motor learning principles, such as repetitive training and feedback and neuroplasticity through repetition, motivation, and reward. The treatment duration of 1h, 5 times a week for 4 weeks, is consistent with previous behavioral interventions for post-stroke dysarthria. This study aimed to determine whether the condition of patients with stroke can be improved through the use of smartphone-based interventions. This is a single-center, investigator-blinded, randomized, crossover effectiveness study. In this study, both the objective and subjective measurements will be performed three times: at baseline, post-phase 1 study (week 4), and post-phase 2 study (week 8). The study includes three intervention cycles, and for each research cycle, 12 subjects will be recruited to participate (6 per each group × 3 cycles).

Conditions

• Stroke
• Motor Speech Disorder

Interventions

Type	Name	Description
BEHAVIORAL	Smart-phone based, self-driven speech rehabilitation	Participants will perform the speech exercises for 60 min per day. Participants may complete the speech exercises all at once or split them into several sessions. Thus, participants assigned to the intervention group will use the application for 30-60 min daily, 5 days per week, for 4 consecutive weeks.
