Immediate Effects of Postural Repositioning on Voice Production Tasks in Seated Individuals With Acquired Dysarthria:
Immediate Effects of Postural Repositioning on Voice Production Tasks in Seated Individuals With Acquired Dysarthria:
To determine the effectiveness of a single 10-min postural repositioning session on the
 maximum phonation duration in individuals with acquired dysarthria.
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.
**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.
