Accelerometer-Based Head Impact Detection In Soccer - Where Are We?, Nipun Chopra

Biology Faculty publications

Traumatic brain injury (TBI) represents a significant burden on individuals, societies, and healthcare systems as it is associated with long-term neurological and behavioral consequences. Although these effects vary according to severity, events that lead to TBI and mild TBI (mTBI), such as concussions, subconcussive impacts, and non-impact violent head movements, may also lead to similar changes. Soccer players are particularly prone to mTBI as they are exposed to head impacts in various ways during training and gameplay. A commonly-claimed TBI risk is that posed by the "heading" technique. Our examination of the literature questions the extent to which heading actually …
