Plain English Summary

Background and study aims
Friedreich's ataxia is an inherited disorder that affects some of the body's nerves and causes difficulty walking, a loss of sensation in the arms and legs, and impaired speech. Evidence for the effectiveness of speech treatment to improve communication for people with Friedreich's ataxia is steadily increasing. A few different treatment approaches have recently been reported, each of them showing some benefits for different aspects important to communication, including the quality of the voice, intelligibility of speech, and communication confidence. However, whilst they each showed promise, no study has been able to show conclusively so far that it can achieve the desired communication benefits for people with progressive ataxia across the board. The critical next step to achieve this is to run a larger scale trial that tells us whether speech therapy is indeed effective across people with ataxia and also, which approach works best. Before this, researchers want to carry out one more pilot study of a newly developed model to help them decide whether this should be considered in the larger trial in future. They need to find out how acceptable this is for people with Friedreich's ataxia, and whether there is any indication it results in better communication.

Who can participate?
Patients aged 18 years and over with Friedreich’s ataxia who experience mild to moderate speech or voice problems, which means people can still understand most of what they say although they might need to listen more carefully

What does the study involve?
The treatment is called LSVT Artic. It includes intensive articulation practice in four 1 hour sessions per week over 4 weeks. It has had positive results for intelligibility in people with Parkinson’s disease. The treatment will be offered online. Participants will be assessed twice before treatment at 4-week intervals and twice after treatment, immediately and 6 months later.

What are the possible benefits and risks of participating?
This therapy has not been done with people with ataxia before and it is not known whether it works. It is hoped that participants' communication will improve as part of the treatment. If it does not, the researchers might be able to suggest other methods that could have more success depending on their speech symptoms. Whatever the outcomes, it is hoped that the study will have wider benefits for people with ataxia and lead to improvements in care in the long term.
The treatment is relatively intensive and participants might experience some fatigue following sessions. The researchers will closely monitor their response to treatment and make adjustments during its course where necessary. There are no known negative side effects of the treatment or any of the assessment tasks.

Scientific titleA feasibility study of LSVT Artic to improve speech performance in people with Friedreich's ataxia
Study hypothesisIt is hypothesised that LSVT Artic will improve participants' intelligibility immediately after treatment and 6 months later.
Ethics approval(s)Approved 25/03/2022, Strathclyde University Ethics Committee (University of Strathclyde, 16 Richmond St, Glasgow, G1 1XQ, UK; +44 (0)141 548 3707; ethics@strath.ac.uk), ref UEC22/24
ConditionFriedreich's ataxia
InterventionParticipants are offered a course of 16 sessions of LSVT Artic over the course of 4 weeks. Prior to this they will have completed a no treatment phrase of the same duration. LSVT Artic consists of four consecutive sessions per week lasting 60 minutes focusing on clear speech production. This will be practised on individual sound segments initially, followed by single words, short then longer phrases, passage reading and free conversation. In addition to the weekly sessions, participants will be asked to complete homework exercises.
Intervention typeBehavioural
Primary outcome measureSpeech outcome measures consisting of:
1. Speed of syllable repetitions (p, t, k, p-t, n-g, oo-ee & oo-ah) is expressed as the average number of repetitions in 5 seconds over 5 attempts at baseline (weeks 1 & 4) and post-treatment (weeks 8 and 32);
2. Clarity of syllable repetitions is judged by trained listeners over 5 attempts at baseline (weeks 1 & 4) and post-treatment (weeks 8 and 32);
3. Intelligibility and naturalness of the reading passage are rated with a Direct Magnitude Evaluation method by trained listeners at weeks 1, 4, 8 and 32;
4. Intelligibility and naturalness of 1 minute monologue samples are rated on a visual analogue scale by trained listeners at weeks 1, 4, 8 and 32.
Secondary outcome measures1. Vowel space is measured through LPC analysis of word repetitions at weeks 1, 4, 8 and 32;
2. Communication confidence is rated on a 1-10 scale by participants at weeks 1, 8 and 32;
3. Communication participation is measured using the Communication Participation Item Bank (Baylor et al. 2013) at weeks 1, 8 and 32.
