Concussions
A concussion is a brain injury caused by a sudden hit, bump or jolt to the head, face, neck or somewhere else on the body. The impact can prevent the brain from working normally. Concussions can happen while playing a sport, from being involved in a motor vehicle collision, from slipping and falling, or other activities. A concussion cannot be seen on X-rays, CT scans or MRI’s.
What to do: Concussion management
A person with a concussion may not know if they are ready to return to activity.
Call 911 or go to the Emergency Department if any of these ‘Red Flag’ symptoms are present:
- Loss of consciousness (do not move the person)
- Seizure or convulsions
- Uncontrollable vomiting
- Worsening mental status
- Neck pain
- Severe or increasing headache
- Trouble with vision
- Slurred speech
- Very tired or lethargic
- Weakness or tingling in arms or legs/unsteady/paralysis
Even if a person is not showing symptoms above:
- Immediately remove the person from the activity
- Do not return to the activity for the rest of the day
- Monitor for signs and symptoms of a concussion
- Ensure they are assessed by a medical doctor or a nurse practitioner
- You do not need to lose consciousness (knocked or blacked out) to have a concussion

Recovering from a Concussion
Physical and mental rest is important for the first 24 to 48 hours after a concussion. Mental rest means no driving, watching T.V., playing video games, reading or working on a computer. After 24 to 48 hours you can gradually become more active.
Returning to activities too quickly and too soon may cause symptoms to get worse or take longer to go away. A person may need to stay home from school or work because regular activities could make their symptoms worse. Talk to your medical doctor to decide when you can drive a car or ride a bike (Your ability to react may be slower after a concussion) and when you can return to normal activities (work or school).
Return to School/Work and Return to Play/Sport
In the following tables:
- Move forward to the next stage only when symptom-free for 24 hours
- If symptoms reappear, go back to previous stages and only participate in activities that you can tolerate.
- Contact your medical doctor if symptoms worsen.
Return to school or work
At home:
Stage | Aim | Activity | Goal of each step |
---|---|---|---|
1 | Cognitive and physical rest for first 24 to 48 hours | Typical activities at home that do not increase symptoms. No TV, computer, cellphone, reading or physical strain | Rest with gradual return to typical activities |
2 | Light cognitive and physical activity | Gradually build up typical activities – easy reading, limited TV, peer contact, school-type work at home. Still no computer, school or work or physical strain | Tolerate up to one hour of cognitive activity in two to three chunks |
At school or work:
Stage | Aim | Activity | Goal of each step |
---|---|---|---|
3 | Part time school or work – light load | Gradual introduction of academic or work activities. Up to 120 minutes of cognitive activity, in intervals. Half days of school or work, one to two times per week | Add movement |
4 | Part time school or work – moderate load | School or work in four to five hours per day, three to five days per week; homework up to 30 minutes per day. No gym, organized sports or exams | Increase academic or work activity |
5 | Nearly normal workload | Nearly normal cognitive activities; routine academic or work as tolerated (homework up to 60 minutes per day, minimal learning accommodation). No gym, exams or organized sports | Increase academic or work activity |
6 | Full time | Normal cognitive and school or work activities; full curriculum load with no learning accommodation. No full participation in sports until medically cleared after Return to Play or Sport protocol | Return to full academic/work activities and catch up on missed work – Can begin to follow Return to Play or Sport protocol |
Return to play or sport:
Stage | Aim | Activity | Goal of each step |
---|---|---|---|
1 | Symptom-limited activity | Daily activities that do not provoke symptoms | Gradual reintroduction of work or school activities |
2 | Light aerobic exercise | Walking or stationary cycling at slow to medium pace - no resistance training | Increase heart rate |
3 | Sport-specific exercise | Running or skating drills - no head impact activities | Add movement |
4 | Non-contact training drills | Harder training drills (such as passing drills) - may start progressive resistance training | Exercise, coordination and increased thinking |
5 | Full contact practice | Following medical clearance, participate in normal training activities | Restore confidence and assess functional skills by coaching staff |
6 | Return to sport | Normal game play |
