About

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.

Full 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).

Enrollment: 44 patients

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients must be able to use a smartphone-based speech therapy application, as determined by self-reporting cognitive abilities.
• Speaks English as a native language.

Exclusion criteria

• Unable to use smartphone application or conduct speech assessment due to severe speech impairment.
• Self-reported co-existing progressive neurological disorders that can affect dysarthria (e.g., dementia, Pick's disease, Huntington's disease, Parkinson's disease, or Parkinsonism).
• Patient with severe mental disorders as self-reported (e.g., depression, schizophrenia, alcohol addiction, or drug addiction).
• Illiterate patients.

Intervention

Experimental group

Description:

Participants in the intervention group will use a speech therapy application, a software designed for post-stroke dysarthria speech therapy and provided in the form of a mobile application. The application provides intensive speech treatment, including respiration, phonation, resonance, prosody, and articulation exercises. The system analyzes patients' voices collected while using the application and delivers the results through real-time visual and summary feedback, increasing patients' ability to self-monitor.

Treatment:

Behavioral: Smart-phone based, self-driven speech rehabilitation

Waitlist control

No Intervention group
