Take Down Technique From A Wrist Grab
By Gene Roos
Editor’s Note: Those in karate might see some similarity in the move demonstrated below to a movement sequence in Pinan kata number three, which uses a horse stance and similar elbow/forearm movement.
You probably have not seen this technique before.
It was new for me too, but necessitated by a physical limitation. One of my students brought his son to class. His son had a medical condition (Palsy). His right side had some ability, but not his left. I had to create techniques that would work with this student’s limitations.
The wrist grab technique shown here worked very effectively for him. You might find it works for you too.

The Attack
The attacker’s right hand grabs the inside of the defender’s right wrist.
The Defense
The defender rotates his right hand counter clockwise (with his thumb down and little finger up). With the elbow pointed upward, the defender’s right hand can then either grab or hook inside the attacker’s right wrist. At the same time the defender takes a step with his right foot angling 45 degrees to his left, the raised elbow pressing up across the opponent’s chest – throwing the opponent down to the rear.
Using this angle of defense, the defender’s right arm becomes “an Unbendable Arm” — a locked striking mechanism that is driven by his body movement.
