With the first concussion, we followed the protocol. It was strict rest until the symptoms went away and then you start a gradual return to sports activity. I believe that the first step was walking for half an hour. The second step was walking for two minutes, running for one minute. Step three was wind sprints for 15 minutes, which was fun. Step four was the return to sport, without physical contact, and then step five was the full return to sport. If you have a symptom provoked at any of the steps, then you have to stop, wait 24 hours and then start at step one again.
