Registered outcomes 9
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Range of movement of the articulators | 2-hr assessment | The range of movement of lips, tongue, and jaw of the participants will be analyzed by the computer vision model of ORAR to give range-of-motion scores. | ClinicalTrials.gov |
| Primary | Maximum phonation time | 2-hr assessment | Each participant will be asked to take a deep breathe and say 'ah' as long as they can. This will repeat for 3 times. | ClinicalTrials.gov |
| Primary | Diadochokinetic (DDK) rate | 2-hr assessment | The number of repeated syllables, trisyllabic non-word, trisyllabic Malay real word (only for Malay participants), trisyllabic English real word produced in 8 seconds will be measured. | ClinicalTrials.gov |
| Primary | Reading aloud a word list | 2-hr assessment | Participants will be asked to read aloud a word list covering phonetic inventory of the language and multisyllabic words (English: 38 words from Robertson Dysarthria Profile; Malay: 30 words selected from Malay Lexicon Project). | ClinicalTrials.gov |
| Primary | Personal narrative production | 2-hr assessment | Participants will be asked to recall a personal event. | ClinicalTrials.gov |
| Primary | Verbal fluency tasks | 2-hr assessment | Participants will be asked to produce as many items in a given category (e.g., fruits, vehicles) within a minute. | ClinicalTrials.gov |
| Primary | Acceptability, appropriateness and feasibility of ORAR | 2-hr assessment | A semi-structured interview will be conducted. Questions regarding the acceptability, apropriateness and feasibility of ORAR app will be asked. | ClinicalTrials.gov |
| Secondary | Eating Assessment Tool (EAT-10) questionnaire as a self-reported outcome instrument on swallowing functions | 2-hr assessment | The questionnaire consists of 10 questions, and participants will be asked to evaluate their swallowing functions based on a 5-point Likert scale (0=not at all; 4=very much). Lower scores reflect better swallowing performance. Maximum and minimal scores are 40 and 0, respectively. | ClinicalTrials.gov |
| Secondary | The Oral Health Impact Profile-14 (OHIP-14) questionnaire to assess oral health-related quality of life | 2-hr assessment | Participants will be asked to give ratings on the questionnaire based on a 5-point Likert scale. Lower scores represent better oral condition-related quality of life. The maximum and minimum scores are 56 and 0, respectively. | ClinicalTrials.gov |
