Rutgers researchers say tools used to diagnose concussions may overestimate the condition, misidentifying symptoms such as fatigue and neck pain that are caused by strenuous exercise rather than brain damage
The new study raises new questions about the Sports Concussion Assessment Tool (SCAT)
"Our findings highlight the importance of considering the effects of exercise and fatigue when evaluating concussions in athletes," said Stephanie Iring, lead author of the study
A concussion is a traumatic brain injury, usually caused by a blow to the head
SCAT is a tool designed for medical professionals to determine if a player has suffered a concussion
In previous studies, the researchers compared symptoms in athletes who received a heavy blow to the head and those who were at rest
Those with head injuries had significantly more symptoms on the SCAT assessment than those with head injuries, reporting an average of 26 symptoms
"Our data show that exerting force during play increases the number and severity of self-reported symptoms in control players, even if they have not experienced head impact ," said Iring
Some symptoms, including headaches and "feeling bad," were more closely linked to head injuries
