Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Kinephonics speech entrainment software is a communication app used on portable devices such as phones, laptops, and tablets. It incorporates multiple outputs of visualisation (camera filming the speaker; written text) and audio (text-to-speech generation) produced simultaneously on the screen. Written text and audio outputs of scripts entered into the software allow the speaker to listen to and read the script, as well as observe their face and mouth while speaking.
Support workers (SW) and allied health assistants (AHA) will be trained by Kinephonics staff to implement the app with adult participants with various etiologies who experience chronic communication disorders. Individual training for each participant's SW/AHA will be completed following the participant's enrollment into the project and prior to their first intervention session (week -1 to week 0).
Each participant will attend 12 in-person intervention sessions over 6 weeks with a SW/AHA for approximately 30 minutes each. The intervention is completed within the community during everyday activities. Family members/carers may also be present during the intervention sessions. support workers/allied health assistants will meet with participants in either their home or a community setting, rather than in a clinic environment.
Examples of exercises could include ordering their regular coffee, common phrases used when buying items in stores, or introducing themselves.
To monitor adherence to the intervention, the SW/AHA will complete a form after each intervention session to record that it occurred and whether there were any issues. SW/AHAs will be trained by Kinephonics staff prior to the intervention period, over 3 20-minute sessions. The SW/AHAs will learn how to use the Kinephonics technology, how to prepare the material and stimulus for each intervention session, and how to run a session with minimal assistance.

The feasibility, acceptability, and adherence to completing the intervention with SW/AHAs for the purpose of conducting a larger clinical trial will be investigated as the primary outcome. Feasibility outcomes include participant fatigue, attendance rate to intervention sessions, and fidelity of intervention delivery is captured. Process evaluation interviews will also be conducted for an in-depth investigation of the trial feasibility with participants and SW/AHAs.
Language outcomes before and after the intervention sessions will also be collected as secondary outcomes of this pilot trial.

20 participants with previous history of stroke will also be enrolled to complete 2 fMRI scans, one before the intervention and one after. These will be the first 20 eligible stroke participants who give consent to participate in fMRI component of the study. fMRI’s will be completed by the research staff of the Research Imaging NSW located at the Prince of Wales Hospital. This scan will take in total 60 minutes.

Comparator / control treatment
Active control group, in which participants will be randomised to the intervention phase or wait list group for the first 6 weeks. At week 7, participants will cross over and enter the intervention phase or wait list period for another 6 weeks. During the wait list period, participants will have no other speech therapy than the study intervention during the study period. Both groups will have study intervention. The difference is the timing of the intervention.
Control group
Active

Outcomes
Primary outcome [1] 332093 0
The proportion of participants with satisfactory adherence to the intervention (attend at least 9 intervention sessions). The SW/AHA will be recording the number of sessions which the participants attend. Additionally, following the completion of the 16-week period, SW/AHAs will be asked to complete interviews about their views on the experience of the intervention, including adherence.

Primary outcome [3] 332095 0
Feasibility of delivering the intervention with SW/AHA measured by qualitative evaluation through semi-structured one-on-one audio-recorded interviews with a member of the research team and the SW/AHA and quantitative evaluation of the study-specific SW/AHA supervision questionnaire and study-specific training sessions. This is a composite outcome.

Serious adverse events will be reported by the participant, their family, or the support worker, to the research team, who will record this information in a study-specific questionnaire. Possible adverse events include any serious medical event (e.g. stroke, fall incident) which may occur during the study period, unrelated to the project. This is included as a result of a higher risk of accidents with this population.

Secondary outcome [5] 413181 0
Additional primary outcome - Acceptability of research procedures and outcome measures determined by the assessment visit attendance rate and proportion of data completed for all outcome measures.
Timepoint [5] 413181 0
At screening, week 6, week 12, and week 16 post-baseline visit.
Secondary outcome [6] 413182 0
Additional primary outcome - Change in Mean Length of Utterance (MLU) of trained words/phrases after phase 1 in patients with developmental or acquired communication disorders.
MLU is a simple, standard speech pathology outcome measure to determine the complexity level of spontaneous speech. It was chosen for this project as a universal measure across all aetiologies of communication disorders, to identify any change in the length and/or complexity of spoken sentences before and after treatment (Stubbs et al., 2018; Condouris, Meyer, & Tager-Flusberg, 2003; Tager-Flusberg et al., 2009). It is calculated by counting the number of words per sentence and identifying the mean number of words across all sentences in a language sample.

Intervention assignment
Other
Other design features
The assignment is similar to a crossover design, in which all participants will receive the intervention and are randomised if they are allocated to the wait list or intervention arm initially. However, the participants in the intervention arm who go on to the wait list at week 7 are not a standard 'control' group as they have previously received the language intervention.

Summary
Brief summary
The Kinephonics app is a new technology to support people with communication difficulties using speech entrainment intervention technique. It is hypothesised the app, with the support from a support worker or allied health assistant, can help adults with a range of backgrounds (including stroke, developmental disorder, autism, brain injury) with improving their speech and language skills. The current study is a pilot study, which will inform the development of a future large clinical trial.
The primary objectives of the study are to a) determine the acceptability and feasibility of conducting the study for a large clinical trial in the future using the Kinephonics app with support workers and allied health assistants implementing the intervention; and b) to determine the effect of the Kinephonics app on various speech and language outcomes.
Following an assessment visit to capture communication outcomes, participants will be randomised to immediate intervention group or waitlist control group. Each group will receive Kinephonics® speech entrainment sessions 20-30 minutes 1-2 weekly for a total of 12 sessions within 6 weeks. Outcomes will be assessed after each intervention/usual care phase, and 1 month after all phases. fMRI neuroimaging on 20 participants with a background of a stroke before and after the intervention to identify neurological changes with Kinephonics® use is an optional component of the study.
Outcomes which will be measured include:
* Number of intervention sessions participants attend
* Support worker and allied health assistants following the Kinephonics training and intervention requirements
* Receptive and expressive language skills before and after the intervention
* Speech skills before and after the intervention
* Fatigue ratings after participating in the intervention
* Optional functional MRI for stroke participants to measure neurological changes
* Optional interview to discuss participant and family experience with being in the study
