Muscle injury triggers a sequence of events that begin with a host inflammatory response that is followed by muscle fiber regeneration and new collagen synthesis. The inflammatory response involves at least three types of cells, including neutrophils, ED1+ macrophages, and ED2+ macrophages. A host of growth factors and cytokines appear to play a role in the inflammatory process and repair of the damaged tissue. Satellite cells play an integral role in normal development of skeletal muscle by providing a source for postmitotic myonuclei. In addition, the satellite cell is essential to the repair of injured muscle by serving as a source of myoblasts for fiber regeneration. At the same time muscle fiber regeneration is occurring, there is expression of types I and III collagen that under certain circumstances can lead to scarring and fibrosis. Current studies of treatment of muscle injury often incorporate investigations of basic principles of injury and repair together with clinical experience and principles in an effort to coordinate basic science and outcome studies.
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 18 May 2021.
All research outputs
#31,186,734
of 34,365,356 outputs
Outputs from Physical medicine and rehabilitation clinics of North America
#604
of 666 outputs
Outputs of similar age
#58,410
of 59,969 outputs
Outputs of similar age from Physical medicine and rehabilitation clinics of North America
#5
of 6 outputs
Altmetric has tracked 34,365,356 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 666 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.9. This one is in the 1st percentile – i.e., 1% 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 59,969 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 6 others from the same source and published within six weeks on either side of this one.
