Concussion and mild traumatic brain injury
Prevention and awareness-raising of the risks of mild traumatic brain injury or concussion
To develop or maintain a healthy and safe environment, each citizen and location needs to adopt a preventive approach. To do this, follow the procedure suggested below to reduce the risk of a mild traumatic brain injury (mTBI) or concussion.
Step 1 – Identify the nature of the risks
Identify the nature of the risks associated with the situation or activity:
- falls, or collisions with objects
- collisions with another person
- authorized physical contacts
- authorized blows to the head (e.g. certain combat sports)
Step 2 – Analyze the risk of mTBI/concussion
Analyze the risk of mTBI/concussion related to the situation or activity by considering:
- the physical environment (facilities, playgrounds, shared equipment, etc.)
- personal equipment (current standards, protective equipment, etc.)
- supervision (workplace health and safety standards, laws and regulations, game rules, severity of penalties, safety instructions, supervision, first aid services, refereeing, etc.)
- participants’ behaviour and attitudes (conditions for participation or for a return to work or school, compliance with game rules and safety instructions, etc.)
Step 3 – Verify if preventive measures should be added
Verify if the situation is satisfactory or if preventive measures should be added to reduce the number or severity of mTBIs/concussions. Preventive measures should:
- be adapted to the context
- be concrete and efficient
- not change the nature of the activity or sport
- be personally, athletically, socially and economically viable
Step 4 – Stop doing the activity when in doubt
Pay attention to your own symptoms, but also those of other people who are participating in the activity. Monitoring is a responsibility that is shared by everyone present. Ask the person to stop doing the activity — or inform those with the authority to do so — in any one of the following situations:
- if the participant presents any concussion symptom(s)
- following an impact to the head or body, or a sudden movement of the head that could cause an mTBI/concussion, with or without immediate symptoms
- if there is any doubt regarding information provided by the participant
- if the person has a history of mTBI/concussion
