Children with congenital myotonic dystrophy (CDM) have communication and motor delays. It's not well studied how communication delays affect performance on functional measures such as four-stair climb (4SC), rise from floor (RFF) and 10-meter run (10MR).
49 participants with CDM were recruited in to three age-based cohorts. Motor performance was assessed in the two oldest cohorts using the 4SC, RFF and 10MR. Each participant's Age Equivalent Receptive Communication was calculated using the Vineland Adaptive Behavior Scales-II.
The 10MR time improved by 6.5% over 12 months. Participant's chronological age suggested/showed significant weak-modest negative correlations for 4SC (r= -.39, p=.032) and 10MR (r= -.39, p=.034). There was no significant correlation between participants age equivalent receptive communication and the 10MR, 4SC, or RFF.
Age equivalent receptive communication doesn't appear to correlate with performance/improvement on these measures. Perhaps suggesting performance on these measures is more closely associated with motor function/planning. This article is protected by copyright. All rights reserved.
This research output has an Altmetric Attention Score of 1. 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 31 December 2017.
All research outputs
#16,137,658
of 23,937,668 outputs
Outputs from Muscle & Nerve
#1,956
of 2,919 outputs
Outputs of similar age
#203,156
of 319,760 outputs
Outputs of similar age from Muscle & Nerve
#24
of 40 outputs
Altmetric has tracked 23,937,668 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,919 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.1. This one is in the 24th percentile – i.e., 24% of its peers scored the same or lower than it.
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 319,760 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 27th percentile – i.e., 27% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 40 others from the same source and published within six weeks on either side of this one. This one is in the 35th percentile – i.e., 35% of its contemporaries scored the same or lower than it.
