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.

Other: postural repositioning
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.
Change in maximum phonation duration
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
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.
Time frame: immediately before postural repositioning intervention
Change in manometry
time prolonged expiration
Time frame: immediately before and after the 10 minute postural repositioning intervention
Change in EMG activation pattern
pattern of electromyographic activity of muscles in the neck and trunk
Time frame: immediately before and after the 10 minute postural repositioning intervention
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.
Time frame: immediately after the 10 minute postural repositioning intervention
Change in the level of satisfaction of participants with their performance assessed using a questionnaire
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
Change in the participant's perceived effort to perform the task using a questionnaire
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

Ran from Jun 2012 to primary completion in Jul 2015, 36 months.
Of 58 non-industry interventional studies with no phase under Signs and Symptoms, half reached primary completion within 22 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 37. This study's 36 months is above that.
Counting every sponsor, half of 69 studies reached it within 17 months; a quarter within 6 and three quarters within 37.
