About this study

Official title: Modifying Unconscious Tongue Movements to Improve Fluency in Adults With a Confirmed Developmental Stammer. A Pilot Randomised Feasibility Study.

This is a pilot randomised controlled trial investigating whether using modification of saccadic eye movements can control lateral unconscious tongue positioning and enhance fluency in adults with a confirmed developmental stammer. This study is being conducted as part of an MSc by research qualification at the Institute of Technology Sligo in Ireland with a view to extending to PhD. The setting is home setting with all assessments either taking place at home via video link or in the institute. The study is being conducted in conjunction with the Community Speech and Language Therapist and has attained ethical approval through Sligo University Hospital (SUH) Ethics Committee.

Read the detailed description

Participants will be assessed for stammering severity either on line via video link or in the Institute of Technology Sligo Health Science \& Exercise Physiology Lab (B2004) at three time points: before intervention, after a five-week trial period and three months post completion. Participants will complete two assessments at each time to cater for "off" days. Participants will be required to practice quick eye movements at the start of words / syllables where dysfluencies are predicted for 10 minutes twice a day for the treatment period. Training in eye movement (saccade) modification will occur following the initial assessment in IT Sligo, or video link.

Participants will be assigned to one of two treatment arms. An experimental arm, and a control (placebo) arm. All participants will be assessed regarding their premonitory awareness of anticipated dysfluencies both before training and at the three month Based on advice from Community Speech and language Manager (Ms Sinead Carthy), participants will voice/video message the principle investigator once per week for this five-week period to confirm compliance.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Modifying saccades by looking down to naval.Behavioural

    Paragraphs from list Provided by Researcher. Participants to read out loud for 10 minutes twice per day for the five week period. On any word they anticipate / experience dysfluencies look quickly down to their naval to reset the lateral tongue position.

  • Modifying saccades by looking in air.Behavioural

    Paragraphs from list provided by Researcher. Participants to read out loud for 10 minutes twice per day for the five week period. On any word they anticipate / experience dysfluencies look quickly up to reset the lateral tongue position.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Stammering Severity (SSI-4) (Howell et. al. 2011).

    Measures stuttering severity in adults and children. It measures the percentage of stuttered syllables versus fluent speech in the participant. It also measures the frequency of repetition and prolongations, duration of blocks, and physical concomitants.

    Measured: 10 minutes.

Secondary outcomes (2)
  1. Stammering Experience Overall Assessment of the Speaker's Experience of Stuttering OASES-A (Yaruss & Quesal 2006).

    Measures the impact of stuttering on a person's life. Scores range between 1 (Mild) and 5 (Severe). The impact is broken down to four sections: General Information, Speaker's reactions, Daily Communication and Quality of life. There is also an overall impact score.

    Measured: 10 minutes.

  2. Premonitory Awareness in Stuttering Scale (PAiS) (Cholin et. al. 2016).

    Measures the anticipation effect in stuttering. 14 items assessing premonitory awareness of stuttering sensation to assess the individual's capacity, manner and style of anticipation. Each item consists of a 4-point Likert scale ranging from "not at all" to "very much". A higher score indicates a larger anticipation of stuttering by the participant.

    Measured: 10 minutes.

Questions about this trial

What is this clinical trial studying?

A study testing Modifying saccades by looking down to naval. and Modifying saccades by looking in air. in people with Stammering, run by Institute of Technology, Sligo at 1 site in Ireland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: paused, as of the sponsor's last update on 26 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Ireland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Stammering Severity (SSI-4) (Howell et. al. 2011). (time frame: 10 minutes.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2024.
