Hi fellow PMR Superstars!! I have a quick bonus video for all of you. Remember, easy questions are worth the same as tough ones! How many times have you seen this question -- "The H-reflex is used to most commonly examine what nerve root?" Answer: S1 of course. But what else can be evaluated with an H-reflex?? Boards love these lesser known questions that are simply a matter of memorization. So I hope to prepare you all by providing you with these bonus videos. Not so much concept oriented, but they are focused on reiterating tricky points so you won't miss them on test day. Sometimes, all you need is to hear something once or twice to have it stick in your mind. For example, "Subscribe to these videos.....subscribe to these videos" :P Thank you guys for your support!
