I've posted several entries on concussions before. This one, posted on NPR today, is about a "new test" that is low tech to help diagnose concussions. For any of you who have done the Activities Manual Volume 1 activity using the yardstick, this will sound very familiar. Health Professionals attach a hockey puck to the end of a stick. The article does a nice job of describing what the test is and is not along with more information on diagnosing concussions. If you should also do the yardstick activity, this will be a nice supplement to it.
