Abstract

Concussion, or mild traumatic brain injury, is a growing concern especially among the pediatric population. By age 25, as many as 30% of the population are likely to have had a concussion. Many result in long term disability, with some evolving to post-concussion syndrome. Treatments are being developed, but are difficult to assess given the lack of measures to quantitatively monitor concussion. There is no accepted quantitative imaging metric for monitoring concussion. We hypothesized that since cognitive function and fiber tracks are often impacted in concussion, inter-hemispheric brain communication may be impaired. Brain function is linked to changes in oxy- and deoxyhemoglobin.. We used functional near-infrared spectroscopy (fNIRS) to quantify functional coherence between the left and right motor cortex as a marker of inter-hemispheric communication. Studies were undertaken during the resting state and with a finger tapping task to activate the motor cortex. Pediatric patients (age 12 to 18) had symptoms for 21-731 days compared with controls who have not had a reported a previous concussion. We detected a differences between patients and controls in coherence between the contralateral motor cortices using measurements of total hemoglobin with a p< 0.01 (n=8 control, n=12 mTBI). Given the critical need for a quantitative biomarker for recovery following aconcussion, we present this data to highlight the potential of fNIRS coupled with inter-hemispheric coherence analysis as a biomarker of concussion injury.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 20. 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 January 2019.
All research outputs
#1,850,724
of 25,373,627 outputs
Outputs from Journal of Neurotrauma
#236
of 2,767 outputs
Outputs of similar age
#23,567
of 279,377 outputs
Outputs of similar age from Journal of Neurotrauma
#8
of 46 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 92nd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,767 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 10.2. This one has done particularly well, scoring higher than 91% 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 279,377 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 91% of its contemporaries.
We're also able to compare this research output to 46 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 82% of its contemporaries.
