Excellent piece of work Janet. Thanks.
Noticed a lot of lateral knee injuries from poor Hanmi Kamae and Tori Fune Kogi Undo and impact trauma injuries from poor Shikko. Been trying to correct those on students to ensure that injuries are minimized. I will send them to your article to emphasize the points. Funny thing though, a lot of my recent knee injuries result from trying to show students how not to do it and why. Surprising how easily the knee can be injured from improper usage.
