Let me first say this (as if it isn't obvious
) I hate $ouff$.
But I see a bunch of people with no medical training complaining about concussion testing and it just fits in with the internet and journalistic ignorance, depending on where the comments are coming from.
I know more than 1 Dr that is involved with the NRL or other top line professional sports, the last thing they will do is jeopardise their careers by doing something like letting a concussed player back on the field.
There was a case a couple of years ago where a Dr associated with a professional RU side in the UK did something unethical to allow a player back on the field and he was banned from practising.
Every single player has a baseline test done before they start playing, whenever concussion is suspected they are tested and the results are compared against their baselines.
As a level 2 trainer I have seen players appeared concussed, but are not, I have also seen players that don't appear to be concussed by are.
I honestly believe the single biggest benefit of an independent Dr assessing concussion is that it would quieten (not silence) the ignorant whingers.
Which is probably enough to justify it.
