Registered outcomes7
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Maximum Tongue Strength | Baseline and within 1 week after completion of the 4-week intervention | Maximum anterior and posterior tongue pressure (kPa) measured with the Iowa Oral Performance Instrument (IOPI). Participants pressed the bulb against the hard palate as forcefully as possible for 3 seconds; three trials were performed at each location and the highest value was used. Higher values indicate greater tongue strength. |
| Primary | Tongue Endurance | Baseline and within 1 week after completion of the 4-week intervention | Anterior and posterior tongue endurance (seconds) measured with the IOPI as the time participants maintained 50% of their maximum tongue pressure. Three trials were performed at each location and the longest duration was used. Longer duration indicates greater endurance. |
| Secondary | Swallowing pressure | Baseline and within 1 week after completion of the 4-week intervention | Typical and effortful swallowing pressures (kPa) measured with the IOPI bulb at the posterior tongue during 3 mL water swallows. The mean of three trials for each task was used. Higher values indicate greater tongue pressure during swallowing. |
| Secondary | Suprahyoid Muscle Activity | Baseline and within 1 week after completion of the 4-week intervention | Peak amplitude (µV) of suprahyoid muscle activity during typical and effortful saliva swallows, measured by surface electromyography. The mean of three peak amplitude values for each task was used. Assessments were performed by a neurologist blinded to group allocation. |
| Secondary | Swallowing-Related Quality of Life (T-SWAL-QOL) | Baseline and within 1 week after completion of the 4-week intervention | Turkish version of the Swallowing Quality of Life Questionnaire, a 44-item questionnaire assessing swallowing-related quality of life across 11 domains. Scores range from 0 to 100, with higher scores indicating better swallowing-related quality of life. |
| Secondary | Dysphagia Symptom Severity (T-EAT-10) | Baseline and within 1 week after completion of the 4-week intervention | Turkish version of the Eating Assessment Tool, a 10-item self-report questionnaire. Each item is scored from 0 (no problem) to 4 (severe problem); total score ranges from 0 to 40, with higher scores indicating more severe swallowing symptoms. A score of 3 or higher indicates clinically relevant swallowing difficulty. |
| Secondary | Functional Oral Intake (FOIS) | Baseline and within 1 week after completion of the 4-week intervention | Functional Oral Intake Scale, a 7-level scale rating oral intake from 1 (nothing by mouth) to 7 (total oral diet with no restrictions). Higher levels indicate better functional oral intake. |
