Article Synopsis
  • - The study analyzed how long-term participation in para-sports affects brain reorganization in the primary motor cortex (M1) of lower limb amputees, building on previous findings from a single Paralympic athlete.
  • - Using functional MRI, researchers evaluated 30 lower limb amputees and found that those with more years of para-sports experience showed increased brain activity in areas related to motor control during muscle contractions of the amputated limb.
  • - Results suggest long-term engagement in para-sports leads to significant brain network reorganization, impacting not just M1 but also other areas like the frontal lobe and visual pathways, indicating a strong relationship between injury, activity, and brain plasticity.
