About this trial

This is an interventional treatment trial for Acquired Dysarthria (Finding) focused on measuring acquired dysarthria, corrected seated posture, maximum phonation duration, electromyographic patterns

Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

**Participants with dysarthria Inclusion criteria

  • sustained a stroke or traumatic brain injury
  • diagnosed with dysarthria
  • impaired postural control following a neurological injury
  • are approaching the end of intensive rehabilitation or have finished intensive rehabilitation
  • express a desire to participate in the research
  • have the capacity to read.

Exclusion criteria

  • had any cognitive impairment that could prevent them from understanding directives or from expressing their opinion about their posture A neurologist clinically assessed the cognitive function of PWDs

    **Control participants

  • never diagnosed with dysarthria or any other voice impairment
  • no comorbidities.
  • no breathing deficits (e.g., asthma, chronic obstructive pulmonary disease)
  • no pathologies in the spinal cord, spinal column, or thoracic cage that could prevent them from freely moving their trunk

    Arm Description

    Outcomes

    Primary Outcome Measures

    Change in maximum phonation duration
    Production of the vowel 'a' as long as possible without running out of air

    Secondary Outcome Measures

    Change in trunk circumference in cm - Pre
    Measure of the circumference of the trunk taken at the level of the xyphoid process using a measuring tape when the participants achieves maximal inspiration and maximal expiration. The difference in circumference between maximal inspiration and maximal expiration is subsequently calculated.
    Change in manometry
    time prolonged expiration
    Change in EMG activation pattern
    pattern of electromyographic activity of muscles in the neck and trunk
    Change in trunk circumference in cm - Post
    Measure of the circumference of the trunk taken at the level of the xyphoid process using a measuring tape when the participants achieves maximal inspiration and maximal expiration. The difference in circumference between maximal inspiration and maximal expiration is subsequently calculated.

    5. Study Description

    Brief Summary
    To determine the effectiveness of a single 10-min postural repositioning session on the maximum phonation duration in individuals with acquired dysarthria.
    Detailed Description
    The impact of dysarthria goes beyond communication. However, there have been no clear directives guiding clinical practice to date, and despite increasing evidence directing treatment, research remains limited and predominantly consists of case studies or case series. Despite the importance of postural control in voice production, the effects of postural alignment on speech production efficiency are either little investigated or not at all explored in the dysarthric population. This study determined the effectiveness of a single 10-min postural repositioning session on the maximum phonation duration (MPD) in individuals with acquired dysarthria.

    Postural repositioning
    Arm Type
    Experimental
    Intervention Type
    Other
    Intervention Name(s)
    postural repositioning
    Intervention Description
    The 10-min transdisciplinary intervention aimed (1) to facilitate and activate axial extension during standing and then during sitting; (2) to actively mobilize the trunk, cervical spine, and pelvic and shoulder girdles during standing and then during sitting; and (3) to adjust the seated position, as needed, with supports to ensure its maintenance throughout the experiment. Cushion, balls, boxes, or rolls were used to stabilize the final seated position.
    Primary Outcome Measure Information:
    Title
    Change in maximum phonation duration
    Description

    Description
    Measure of the circumference of the trunk taken at the level of the xyphoid process using a measuring tape when the participants achieves maximal inspiration and maximal expiration. The difference in circumference between maximal inspiration and maximal expiration is subsequently calculated.
