Waza details

The Ude-hishigi-te-gatame (Hand lock) Waza is almost always transitioned to from a Katame waza (Grappling techniques) such as the Kesa-gatame (Scarf hold) or the Yoko-shiho-gatame (Side four-corner hold), etc., and it has several variations.
When transitioned to from the Kesa-gatame (Scarf hold), this Waza as applied to the arm which Tori (Player executing technique) grasps.
Tori (Player executing technique) grasps the wrist of Uke (Player receiving opponent's attack) arm and lays the across the thigh of his own wide-spread leg, then presses the lower part of the arm downward to bend the elbow in the reverse direction.
When transitioned to from the Yoko-shiho-gatame (Side four-corner hold), Tori (Player executing technique) applies the Waza to Uke (Player receiving opponent's attack) arm in the same manner. While holding Uke (Player receiving opponent's attack) down, Tori (Player executing technique) grasps Uke (Player receiving opponent's attack) arm and moves Uke (Player receiving opponent's attack) other arm to Uke (Player receiving opponent's attack) wrist position. Tori (Player executing technique) then moves his other hand (the hand that was squeezing Uke (Player receiving opponent's attack) side) to Uke (Player receiving opponent's attack) elbow position, and with the back of the hand facing up, he firmly clasps his own opposite-side arm with it.
Tori (Player executing technique) then uses the hand beneath Uke (Player receiving opponent's attack) elbow as the fulcrum, and presses Uke (Player receiving opponent's attack) wrist with the other hand to bend the elbow in the reverse direction, thereby locking the elbow joint in accordance with the "lever principle".
