Re: Aikido injuries
Unfortunately, Injuries happen. Sometimes it can be accidental. Sometimes it can be done out of ignorance (not knowing how to take care your Uke). And sometimes it's just not caring. Sometimes it can be malice. The middle two are pretty preventable, if you see a nage and nage looks like nage's not taking care of uke and it looks like he might hurt you don't train with said nage. Whether it's an instructor or a peer, If they don't take care of Uke, they lose the right to train.
As previously stated this might be a repuatation caused by a small injury that was purely accidental. My advice, talk with your daughter. She's made it to med school so she's obviously smart enough and observant enough to make her own decision about her training and life.
