Proof-of-concept Study of LUNA Intervention in Aphasia (LUNA)
Linguistic Underpinnings of Narrative in Aphasia (LUNA): A Proof-of-concept Study of a Novel Discourse Treatment for Aphasia Using Personal Narratives
Study Overview
Detailed Description
One third of stroke survivors have aphasia (a language impairment) which negatively affects communication, relationships, work, socialising, and wellbeing. Speech and language therapy is effective at improving language outcomes for people with aphasia (PWA) but gains in saying words and sentences rarely translate into gains in everyday talking (discourse). Most evidence generated over the last 40 years does not consider how words, sentences and everyday talk are linked together. Recent research signals new approaches are needed targeting multiple levels of language within the same treatment, and treatment needs to explicitly target everyday talking. Research conducted with stakeholders confirms new discourse treatments are a priority to clinicians and researchers, and improved everyday talking is prioritised by PWA as an outcome from rehabilitation.
The proposed research addresses the gap in the evidence base for a theoretically-underpinned multilevel discourse treatment for PWA. The project is titled LUNA and stands for Linguistic Underpinnings of Narrative in Aphasia. It focusses on personal narratives, that is, the short stories people tell others e.g. about recent holiday, funniest memory from school/ work, memorable life moments, etc. Personal stories are central to everyday talking; are important in health, recovery and adjustment; and are commonly used in clinical practice i.e. 70% of speech and language therapists (SLTs) the investigators surveyed in the United Kingdom ask patients to tell personal stories during rehabilitation. LUNA draws on existing word and sentence level treatments that are known to be effective in improving language. The discourse literature is less developed, but describes strategies that similarly feature in LUNA treatment (e.g. telling the key elements of a story and doing so in the correct order so the listener understands). LUNA integrates these and works directly with the participant to improve their own stories. Choosing personalised vocabulary (i.e. the person's own words) increases motivation. Finally, LUNA teaches the person about their language, so they understand their difficulties, thereby empowering them to make connections from clinic to their real life use of talking.
In response to the COVID 19 crisis the investigators plan to conduct all data collection remotely, via video conferencing technology. There is growing evidence that telehealth can be employed successfully in aphasia rehabilitation. Remote administration of aphasia assessment has been shown to be valid, reliable and acceptable to people with aphasia. While not extensively tested, remote therapy has also proved feasible and has produced outcomes that are similar to those achieved by face to face delivery. This study aims to add to the evidence for aphasia tele-rehabilitation by testing the first application of remote discourse therapy.
Aims:
This study will test feasibility of LUNA in terms of participant recruitment and retention, and adherence throughout the study (assessment and treatment sessions). It will explore participant acceptability of LUNA and project procedures (satisfaction, perceived benefits, assessment and treatment burden) in semi-structured individual interviews with participants.
It will investigate initial efficacy by comparing outcomes on a range of measures across participants who have and have not received LUNA intervention. It will assess treatment fidelity by reviewing a sample of videotaped sessions to check they were delivered as intended by the treatment manual. The study will also test the feasibility and acceptability of remote assessment and treatment delivery. For example, recruitment, retention and compliance data will attempt to identify losses due to technological factors; and interview questions will explicitly probe the experience of using video-conferencing technology.
Indicative outcome data will be for remote (not face-to-face) LUNA.
Design:
The study is a single-blind, waitlist, randomised controlled trial of LUNA for people with chronic post-stroke aphasia. Participants will complete assessments at three time points: T1 (weeks 1&2), T2 (weeks 13 & 14) and T3 (weeks 25 & 26). Following T1, participants will be randomised to an immediate or delayed condition. Those in the immediate condition will receive LUNA therapy between T1 and T2. Those in the delayed condition will receive LUNA therapy between T2 and T3. All participants will be invited to participate in in-depth individual semi-structured interviews post-therapy to explore their experiences of taking part in the study.
In line with selection criteria, participants will not be receiving any other speech and language therapy during the study. Owing to COVID 19, it is anticipated that most participants will not have access to usual care (attendance at stroke groups). Some may access on-line supports, for example provided by Aphasia Re-Connect. Use of such services is not an exclusion criterion. Use of other services will be explored in the interviews.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Immediate LUNA intervention
LUNA intervention between T1 and T2.
No treatment between T2 and T3.
LUNA intervention comprises 20hrs of face-to-face treatment, 2 sessions per week of 60 minutes each, for 10 weeks.
One session is delivered by a qualified speech and language therapist; the other session is delivered by an assistant (student or volunteer) following guidance and under distance supervision.
Both therapist and assistant will receive LUNA training.
The treatment is specified in the TIDIER checklist.
In brief, it aims to improve spoken discourse production, using personal narratives as assessment and treatment stimulate, and by integrating word, sentence and discourse level tasks.
Treatment is manualised and has been codesigned with key stakeholders (providers and users).

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Personal narratives measure (LUNA Discourse Protocol)
Time Frame: Change from baseline (T1: weeks 1 and 2) to immediately post treatment (T2: weeks 13 and 14) to follow up (T3: weeks 25 and 26)
|
Participants will produce two personal narratives at each assessment point, which will be video/audio recorded.
They will be given instructions e.g.
length of narrative, indication of topic etc.
The narrative will be spoken face-to-face to the assessing therapist.
S/he will not provide any cues or ask questions.
Recording will cease when the participant indicates that the story is finished.
Discourse samples will be analysed according to the LUNA Research Discourse Analysis Protocol.
The analysis yields the following data: number and %narrative words, and number of narrative words/minute; %Correct Information Units( CIU); number of CIUs/minute; %complete utterances; %single versus multi-clause utterances; #1, 2, and 3 argument utterances; Predicate Argument Score; story grammar count of elements; global coherence score; local coherence score; reference chains count; and overall listener judgment.
Number of narrative words is proposed as the primary discourse outcome.

Time Frame: Change from baseline (T1: weeks 1 and 2) to immediately post treatment (T2: weeks 13 and 14) to follow up (T3: weeks 25 and 26)
|
Tests speaking, auditory comprehension, naming and repetition across 4 sections.
Takes 30-45 minutes.
Internationally used language functioning test; also recommended internally as a core outcome measure.
Provides information on type of aphasia, and severity.
|
Change from baseline (T1: weeks 1 and 2) to immediately post treatment (T2: weeks 13 and 14) to follow up (T3: weeks 25 and 26)
|
The Communicative Participation Item Bank (CPIB) - General Short Form [Patient Reported Outcome Measure]
Time Frame: Change from baseline (T1: weeks 1 and 2) to immediately post treatment (T2: weeks 13 and 14) to follow up (T3: weeks 25 and 26)
|
10 items.
Items are worded as the degree to which the person's condition interferes with e.g.
communicating when out in the community.
Designed for adults with communication disorders with substantial input from individuals themselves.
Short form recently proven appropriate for people with aphasia (Baylor et al., 2017).
We anticipate overlap in item content of the CPIB with the ALA, however, we are intentionally including this instrument as it is possible that this much shorter instrument may be more acceptable (for its brevity) and on post-hoc analysis from the interviews, may align more with participants' perceptions of benefit from the intervention.
This will contribute to decision-making for a future large trial.

Time Frame: Change from baseline (T1: weeks 1 and 2) to immediately post treatment (T2: weeks 13 and 14) to follow up (T3: weeks 25 and 26)
|
Following feedback from our advisors with aphasia (and supported by the research team), a single item mood measure, the Visual Analogue Mood Scales (VAMS) Sad scale (Stern et al., 1997) was added to all testing time points.
It has been used successfully in aphasia studies (Marshall et al., 2019; Thomas et al., 2013) and takes 3 minutes to complete.
It is accessible and appropriate to be used with stroke survivors who have aphasia.
Content validity has been established (Nyenhuis et al., 1997; Stern et al., 1997) and test re-test reliability (House et al., 2012).
