There is no question that concussion is among the more concerning injuries in sport today. The question is how to best detect, assess, treat and prevent it.

Researchers at the ��ݮ����Ƶ����’s  have played an integral role in shaping an international consensus on recognizing and treating concussion in sport. The document,  was published on April 26 in two special editions of the prestigious  

“This consensus was built on the latest scientific evidence and will have a profound impact diagnosing and treating sport-related concussions,” says Dr. Willem Meeuwisse, a sport medicine physician and epidemiologist who co-chaired the consensus conference. “While most people recover in the initial 10- to 14-day time period following injury, in some cases individuals may have symptoms that may persist.”

This consensus statement builds on the previous 4th Conference in Zurich and updates the assessment tools in light of the new evidence.

'Recognize and Remove' is essential

The document was written to assist doctors and health professionals in the care of athletes of all levels, including adults and children, who may have suffered a concussion. It also includes a tool with specific information for the general public and a specific tool for use in children under the age of 12.

“The new tools created from this consensus are designed to assist parents, coaches, officials and players to identify athletes with a potential concussion and remove the athlete from further risk of injury,” says Carolyn Emery, PhD, physiotherapist and professor in the Faculty of Kinesiology.

“The overriding theme presented in this document is Recognize and Remove. In other words, when concussion is suspected, the athlete should be removed from the sporting environment and a comprehensive assessment should be conducted in a standardized way. If a concussion is diagnosed, they should not return to sport the same day,” adds Meeuwisse.

International collaboration comes up with unified answer 

Recognizing the impact of this potentially serious injury, the world’s biggest sport bodies have helped support the consensus process and the statement created by scientists studying the current literature. These organizations include the International Ice Hockey Federation (IIHF), the International Olympic Committee (IOC), Fédération Internationale de Football Association (FIFA), World Rugby, and the International Federation for Equestrian Sports (FEI).

More than 400 academics from 24 countries participated in the fifth International Consensus Conference in Berlin in October 2016. Over the past two years, a scientific committee and expert panel of 33 individuals from around the globe with expertise in sport concussion, contributed through defining the key questions, completing literature reviews, and meeting to come to a consensus on the research presented at the conference. The consensus statement is the summary of a list of specific topics the expert panel agreed upon.  

“One of the amazing things about this document is that it is a collaborative achievement by many people across the globe with different areas of expertise in sport-related concussion who have collaborated to come up with a unified answer to key questions in concussion,” says Kathryn Schneider, PhD, physiotherapist and assistant professor in the Faculty of Kinesiology.

Sport Injury Prevention Research Centre plays key role

Three faculty members from the Sport Injury Prevention Research Centre in the Faculty of Kinesiology at the ��ݮ����Ƶ���� were involved in the process. The Sport Injury Prevention Research Centre is one of 10 IOC Centres of Excellence in Injury and Illness Prevention in Sport in the world.

Willem Meeuwisse co-chaired the consensus conference, known as the 5th International Consensus Conference on Concussion in Sport. Schneider and Emery played key roles, each leading one of the 12 key topic areas and systematic reviews addressed at the meeting on treatment and prevention, respectively. 

A systematic review collects and critically analyzes multiple research studies or papers. These 12 papers were the basis upon which the consensus statement was written. 

Previous consensus statements have been among the most highly cited papers in the area of sport-related concussion, with the fourth international consensus statement cited more than 1,500 times and a pdf version of the Sport Concussion Assessment Tool (SCAT3) downloaded more than 100,000 times.

Key points related to concussion for the general public

• A concussion should be suspected if any symptoms (such as headache, dizziness, blurred vision, etc.) and/or visible signs of a concussion (lying motionless, slow to get up, disorientation, balance disturbances, etc.) occur following a blow to the head.
• Athletes should be removed from play and not allowed to return to play until medically assessed and cleared by a physician to return to sport.
• Initially, a period of rest (24 to 48 hours) is recommended. After this time individuals are encouraged to become gradually more active and remain below their symptom threshold.
• Most adults recover in 10-14 days and most children recover in the initial 30 days. Treatment should be directed based on individualized comprehensive assessments and could include treatments such as psychological, cervical and vestibular rehabilitation. Submaximal exercise may be of benefit.
• Children should return to school prior to returning to sport.
• A gradual return to sport protocol should be completed prior to medical clearance to return to sport.
