Primary purpose: TREATMENT

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.

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.

Primary outcomes:
measure: Change in maximum phonation duration
timeFrame: immediately before and after the 10 minute postural repositioning intervention
Secondary outcomes:
measure: Change in trunk circumference in cm - Pre
timeFrame: immediately before postural repositioning intervention
measure: Change in manometry
timeFrame: immediately before and after the 10 minute postural repositioning intervention
measure: Change in EMG activation pattern
timeFrame: immediately before and after the 10 minute postural repositioning intervention
measure: Change in trunk circumference in cm - Post
timeFrame: immediately after the 10 minute postural repositioning intervention
Other outcomes:
measure: Change in the level of satisfaction of participants with their performance assessed using a questionnaire
timeFrame: immediately before and after the 10 minute postural repositioning intervention
measure: Change in the participant's perceived effort to perform the task using a questionnaire
timeFrame: immediately before and after the 10 minute postural repositioning intervention
