Concussion May Lead to Permanent Changes in Spinal Cord Motor Nerve Pathways

Article title: Altered corticomotor latencies but normal motor neuroplasticity in concussed athletes

Authors: William Stokes, Jake Choynowki, Maria St. Pierre, Manuel Alejandro Anaya, Matthew A. Statton, Pablo A. Celnik, Gabriela Cantarero

From the authors: “We found that the number of concussions an individual sustains negatively impacts corticomotor latencies with a higher number of prior concussions correlating positively with longer latencies. Our findings indicate that concussions may lead to permanent changes in the corticospinal tract that are exacerbated by repeated injury.”

This study is highlighted as one of April’s “best of the best” as part of the American Physiological Society’s APSselect program.
