Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The pre-assessment will include outcome measures listed (i.e., Frenchay Dysarthria Assessment, Assessment of Intelligibility in Dysarthric speech (ASSIDS), self-report questionnaires) and be conducted face to face, one on one, by a speech pathologist not involved in the participant's treatment in a quiet room, with consistent audio recording procedures including using a mp3 audio recorder and condenser headset microphone positioned at a 5cm mouth-to-microphone distance.

Following this, the treating Speech Pathologist (SP) will use pre-assessment results to inform identification of an externally focussed, tailored clear speech strategy for each participant targeting speech intelligibility. Each participant will then undergo two one-on-one sessions scheduled with their treating SP involving instatement of the clear speech strategies, using principles of motor learning as per Park et al’s ‘Be clear’ treatment. These will aim to be on two separate days (across two consecutive days) for approximately 50min in duration and take place approximately 1-2 days prior to commencing either individual or group therapy participants.

Group therapy:
Participants allocated to receive group therapy will receive 12 sessions of group therapy delivered for 50 min, 4 days/week for 3 weeks by an SP based on the “Be clear” dysarthria treatment protocol, consistent with principles of motor learning and neuroplasticity principles of intensity, repetition, specificity and saliency. Group therapy will consist of a maximum of four participants with dysarthria and may also include other patients not part of the research study (i.e., outpatients). Sessions will take place in a group room face to face in the Speech Pathology department of the Gold Coast University Hospital. Tasks each group session will include:
- reminder of clear speech strategies (i.e., written on white board)
- practicing clear speech strategies in spoken functional phrases (developed collaboratively for each individual), service requests and functional speech tasks (alternating between reading, picture description and conversational speech tasks with self-ratings). Tasks are practiced in a combination of alternating turns, group speaking and in pairs with feedback provided by other pair members and SP in accordance with principles of motor learning.
-Homework tasks to transfer practice outside the therapy environment will also be provided (e.g., making phone calls).


- Treatment adherence:
Up to 10% of sessions (of both group and individual therapy) will be randomly video-recorded and reviewed according to a prescribed data coding tool to measure adherence to key elements of the programme.

-Participant attendance & recruitment:
The treating SP will record attendance across both models.

As active participation is required for treatment, participant and SP blinding to treatment allocation is not possible. SPs undertaking everyday communication and speech intelligibility measures however will be blinded to treatment allocation and the assessment time-point.

Rehabilitation
Comparator / control treatment
The control group will include treatment provided by a speech pathologist individually to the participant. Approximately 1-2 days after completing the instatement phase, individual treatment will begin. Treatment will use the same “clear speech” strategies identified by the SP in the instatement phase practised in functional phrases, service requests, and connected speech tasks with training of self-monitoring skills to promote self-efficacy and self-management also incorporated, Treatment will be offered at the same frequency (i.e., for 50 min, 4 days/week for 3 weeks) and delivered by a speech pathologist face to face in a speech pathology treatment room at Gold Coast University Hospital.
A total of 14 individual sessions will be provided (i.e., two one on one sessions during the instatement phase and 12 one one one sessions as part of the comparator intervention).

Eligibility
Key inclusion criteria
There are three participant groups:

1)Dysarthria participants:
Adult inpatients with dysarthria from stroke or acquired brain injury (as diagnosed by a speech pathologist [SP]).

2)Caregiver participants:
Caregivers of participants who have consented to receive treatment in the study and who are proficient in English will be invited to complete two questionnaires.

3) Speech Pathologists:
Approximately 6-8 SPs employed by GCH providing or assessment in the study at the time of the research will be invited to participate.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1) Dysarthria participants:
Significant aphasia or apraxia of speech that would preclude participation in dysarthria therapy, as judged by the treating SP based on completion of routine language screening. As a guide, participants who have greater than a mild aphasia (i.e., <76 on the Western Aphasia Battery bedside screener) will be excluded.
Diagnosis of dementia, currently in post-traumatic amnesia as documented in the patient’s medical record.
Cognitive impairment impacting on their ability to participate in dysarthria therapy as judged by the treating multi-disciplinary team. As a guide, scores <22 on the Montreal Cognitive Assessment (MOCA) indicating impairments greater than a mild cognitive impairment will be excluded.
Significant hearing loss (i.e., profound deafness) or perceptual impairment as documented in the medical record that would preclude the participant from interacting in dysarthria therapy.
Very severe dysarthria or anarthria (total loss of speech) which would preclude ability to participate in group-based therapy based on clinical judgement of a SP. As per definition of severe dysarthria from the AUsTOMs, this may include extremely restricted range of phoneme production (e.g., only one sound class such as vowels or extremely limited strength, range and/or rate of oral movements or control.
Not proficient in English prior to onset of dysarthria.

2)Caregiver participants:
Caregivers <18 years or who self-report any health issue which would prevent them from completing a questionnaire will be excluded.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The study statistician, who is blinded to participant identification, will undertake the randomization and provide treatment allocation to a SP researcher.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
An adaptive randomisation method will be used which enables groups to be filled randomly but with greatest efficiency while also ensuring a balanced design. This method was designed specifically for this study using the random number generator function of Excel.

Efficacy
Statistical methods / analysis
Being a pilot study, descriptive statistics (means, 95% CIs) will be reported across outcome measures including health resource utilisation and cost measures. Qualitative content analysis will be used for the free-form questionnaire responses and transcribed focus group interviews. This will involve two members of the research team grouping related meaning units into categories and subcategories in NVivo. Any coding discrepancies will be reviewed by a third member of the research team.
