Gokyo, besides being a small town in the foothills of the Himalayas, is the fifth teaching, a control technique generally used in knife attacks.
In gokyo, the arm is stretched from the wrist in the opposite direction to the natural elbow, resulting in a dislocation. Its execution, understanding, and meaning vary greatly from one school to another. In general, while tori holds uke's arm pulling with one hand, he controls the elbow with the other, in the opposite direction to the joint's natural movement.
