Official title
A Prospective, Randomized, Multi-Centered Clinical Trial to Investigate the Effectiveness of Smartphone-Based Speech Therapy for People with Post-Stroke Dysarthria
Overview
This clinical trial aims to determine if a new smartphone-based speech therapy is effective self-treatment method for patients with post-stroke dysarthria. For this study, participants in the intervention group will use the speech therapy app for 1 hour per day, 5 days per week, over a 4-week period. The active control group will receive home-based speech therapy with the same duration and frequency as the intervention group. The study will help us understand if smartphone-based speech therapy is a viable treatment option for post-stroke dysarthria patients.
Detailed description
In this study, 100 patients with post-stroke dysarthria will be recruited and stratified into acute-subacute (within 1 month after index stroke) and chronic (after 6 months after index stroke) groups. Participants will then be randomly assigned to either the intervention or active control group.
Patients in the intervention group will use a smartphone-based speech therapy app that includes oro-motor exercise, phonation, articulation, resonance, syllable repetition, and reading exercises. Treatment goals and contents will be determined based on individual patient conditions by a speech-language pathologist after the baseline evaluation. Participants will receive daily sessions for 1 hour per day, 5 days per week, over a 4-week period.
Patients in the active control group will receive home-based speech therapy, which includes oro-motor exercises and reading tasks from a workbook, for the same frequency as the intervention group. Both groups will also receive usual stroke care.
The study aims to evaluate the efficacy of mobile-based speech therapy compared to home-based speech therapy in improving speech intelligibility scores 4 weeks after baseline for patients with dysarthria in the acute-subacute and chronic phases following stroke.
Interventions
- Device Smartphone-based speech therapy
Participants will be instructed to use the speech therapy app for 1 hour per day (5 days for 1 week) over a 4-week period. - Other Home-based speech therapy
Participants will receive treatment maintaining the same frequency as the intervention group.
Primary outcome measures
- Speech intelligibility [Time frame: Baseline, 4 weeks]
Secondary outcome measures (3)
- Maximum phonation Time (MPT) [Time frame: Baseline, 4 weeks]
- Oral-diadochokinesis (DDK) [Time frame: Baseline, 4 weeks]
- Percentage of Consonants Correct (PCC, %) [Time frame: Baseline, 4 weeks]
Eligibility criteria
Inclusion criteria
- Aged 18 or over.
- Neurologically stable stroke patients diagnosed by a stroke specialist neurologist.
- Diagnosis of dysarthria caused by stroke as confirmed by a stroke specialty neurologist.
- First-ever stroke patients without previous stroke history.
- Patients with sufficient cognitive abilities to operate the smartphone-based speech therapy application (Mini-Mental State Exam score ≥ 26)

- Must have voluntarily understood the trial and signed a consent form agreeing to comply with precautions.
Exclusion criteria
- Co-existing language disorder (e.g., aphasia). Aphasia will be determined by a stroke specialist.

- Diagnosis of severe mental disorders as determined by a clinician (e.g., depression, schizophrenia, alcohol addiction, or drug addiction).
- Patients taking concomitant medications that could affect the trial results during the study period (e.g., cognitive dysfunction medications, anticholinergics, anti-epileptic drugs, anti-anxiety drugs, antidepressants, antipsychotics, and hypnotics).
- Patients unable to use/access smartphone technology.
- Illiterate patients.
- Patients unable to communicate in Korean.
- Is unsuitable for participation due to other reasons, as determined by the investigator.
- Has refused to participate in the study.
