The Buffalo Clinic has a protocol to get athletes who have suffered a concussion active by slowly upping their exercise levels. They start by doing a treadmill test to find the max pulse rate before symptoms return. They then set an exercise rate that is at a substantially lower symptom free pulse rate.

The exercise is kept at the lower pulse rate for a prescribed period than increased to the next level. This slow stepping up of the exercise level/pulse rate eventually allows the athlete to exercise at pre-injury levels.

This protocol is more about return to play that recovery from the concussion. There has been no research to verify the ability for the brain to tolerate another impact or even a simple jarring event.

It has been successful at returning athletes to their pre-injury exercise/exertion levels.
