Amyotrophic lateral sclerosis (ALS) affects the speech motor system and causes a substantial decline in intelligibility. Clear speech strategies have been found to benefit intelligibility in talkers with dysarthria and the purpose of this study was to examine clear speech effects on tongue, lip, and jaw movements in persons with ALS and healthy controls. For this purpose, participants produced 10 repetitions of the sentence 'I owe you a yoyo' using both habitual and clear speech. Movement variability as well as maximum speed, range, and duration of movement of the articulators were obtained for both conditions. The results show significantly lower jaw movement variability during habitual speech but greater variability for clear speech in ALS relative to controls. The kinematic data was consistent with expectations for individuals with dysarthria. Based on these results, clear speech may be considered a mode of speech that produces high movement variability in talkers with ALS.
This research output has an Altmetric Attention Score of 10. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 June 2018.
All research outputs
#4,287,173
of 32,282,066 outputs
Outputs from Clinical Linguistics & Phonetics
#30
of 569 outputs
Outputs of similar age
#59,357
of 346,585 outputs
Outputs of similar age from Clinical Linguistics & Phonetics
#1
of 15 outputs
Altmetric has tracked 32,282,066 research outputs across all sources so far. Compared to these this one has done well and is in the 86th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 569 research outputs from this source. They receive a mean Attention Score of 3.5. This one has done particularly well, scoring higher than 94% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 346,585 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 82% of its contemporaries.
We're also able to compare this research output to 15 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 93% of its contemporaries.
