About

The goal of this interventional study is to evaluate the efficacy and safety of a digital therapeutic (DTx) application, 'repeech', for the treatment of post-stroke dysarthria. The study aims to assess improvement in speech intelligibility in individuals affected by post-stroke dysarthria using the DTx intervention.

Full description

This study will evaluate a digital therapeutic (DTx), 'repeech', designed to complement tradtional speech therapy by addressing challenges such as accessibility, frequency of sessions, and personalized feedback. The 'repeech' offers an at-home, customzied intervention, providing patients with more flexible and accessible therapy options. It also encourage greater patient engagement in their treatment and promotes self-care.

The study is designed to assess the efficacy of the 'repeech' in improving speech function, especially speech intelligibility in individuals with post-stroke dysarthria. The clinical trial will be conducted across multiple sites to gather comprehensive data on the intervention's effectiveness and usability.

Inclusion criteria

1. Participants must be 19 years of age or older.
2. Participants must be neurologically stable post-stroke, as determined by a qualified physician.
3. Participants must have dysarthria due to stroke, with a National Institutes of Health Stroke Scale (NIHSS) score 1 (mild) or 2 (moderate) for dysarthria.
4. participants must have a Korean-Modified Mini-Mental State Examination (K-MMSE) score of 26 or higher within 1 month prior to enrollment in the study.
5. Participants must have sufficient visual, auditory, langauge, and motor abilities to understand and follow the assessment procedures, as determined by the Principal Investigator.

7. Participants must provide informed consent after receiving a thorough explanation of the study, including potential risks and benefits. They must understand and agree to follow the study protocol.

Exclusion criteria

1. Participants with sigificant structural problems affecting the oral cavity and cervial region that would hinder accurate assessment.

5. Participants with severe mental health conditions including severe depression, schizophrenia, alcohol addicsion, drug dependence.
6. Participants with a severe langauge disorder, as determined by the physician(MD), that would significantly hinder their abiity to use digital therapeutics platform.
7. Participants deemed by the MD as unable to use general-purpose digital equipment.
8. Participants with additional medical or social concerns that, in the opinion of the Prindipal Investigator(PI), would make their participation in the clinical trial unsuitable or pose siginficant risks.
