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
**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
- no neurological or cardiac problems.

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.

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
Production of the vowel 'a' as long as possible without running out of air
Time Frame
immediately before and after the 10 minute postural repositioning intervention
Secondary Outcome Measure Information:
Title
Change in trunk circumference in cm - Pre
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.
Time Frame
immediately before postural repositioning intervention
Title
Change in manometry
Description
time prolonged expiration
Time Frame
immediately before and after the 10 minute postural repositioning intervention
Title
Change in EMG activation pattern
Description
pattern of electromyographic activity of muscles in the neck and trunk
Time Frame
immediately before and after the 10 minute postural repositioning intervention
Title
Change in trunk circumference in cm - Post
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.
Time Frame
immediately after the 10 minute postural repositioning intervention
Other Pre-specified Outcome Measures:
Title
Change in the level of satisfaction of participants with their performance assessed using a questionnaire
Description
Following completion of voice tasks, the participants will be asked to grade their perceived level of performance in each posture (before and after the postural repositioning intervention) using the NER-21 scale. The participants are instructed to judge their vocal performance on the performance scale
Time Frame
immediately before and after the 10 minute postural repositioning intervention
Title
Change in the participant's perceived effort to perform the task using a questionnaire
Description
Following completion of voice tasks, the participants will be asked to grade their effort in each posture (before and after the postural repositioning intervention) using the NER-21 scale. The participants are instructed to indicate the effort required to speak on the effort scale
Time Frame
immediately before and after the 10 minute postural repositioning intervention
