Laboratory-based studies on neuromuscular control after concussion and epidemiological studies suggest that concussion may increase the risk of subsequent musculoskeletal injury.


Concussion is common in the sporting arena and is often challenging to diagnose.

Injury rates compare the relative frequency of sport-related concussions across groups. However, they may not be intuitive to policy makers, parents, or coaches in understanding the likelihood of concussion.

Hiroshi Yokota’s article “Acute subdural hematoma in judo player with repeated head injuries” shines a light on the serious risks of traumatic brain injuries associated with the traditional Japanese sport of judo, and of a relative lack of policies and guidelines for proper handling of concussion in young athletes more generally.

Mild traumatic brain injury, often referred to as concussion, is a common, potentially debilitating, and costly condition.

We review current topics in sport-related head injuries including acute subdural hematoma (ASDH), traumatic cerebrovascular disease, cerebral concussion, and chronic traumatic encephalopathy (CTE).
