It's the same. There's lots of research here. People are doing trials looking at neck strengthening with all kinds of fancy gizmos, and the data is just not there yet.
If I may, I will come back to one other comment that was made earlier from the NDP member about baseline testing. Not only is there the changing baseline in children but I think the problem is actually much simpler at the grassroots level. We really just need to get that out, that when in doubt, sit them out.
The reason we do these enhanced things with athletes is that they're in the middle of the playoffs, or the Olympics are coming up and it's once every four years or once in a lifetime for them. We're trying to see how quickly we can get them back and when it is safe. However, when we're talking about a child's brain, we don't need neuropsychological tests to assess them, because we shouldn't be pushing the envelope to get them back to high-risk situations.
