Features of this Waza

Waza details

This Ude-hishigi-ashi-gatame (Leg lock) Waza has several variations, and it can be applied with the opponent either in a prone or supine (Kesa-gatame (Scarf hold), etc.) posture.
If Uke (Player receiving opponent's attack) is in a prone posture, Tori (Player executing technique) grasps one of Uke (Player receiving opponent's attack) arms and wraps a leg around it while lowering his upper body across Uke (Player receiving opponent's attack) back. Tori (Player executing technique) then clasps the leg which is around Uke (Player receiving opponent's attack) arm to his other leg to form the shape of a "4" numeral, and scissors Uke (Player receiving opponent's attack) elbow. From this posture, Tori (Player executing technique) bends his body back to bend Uke (Player receiving opponent's attack) elbow in the reverse direction.
If Uke (Player receiving opponent's attack) is in a supine posture (Kesa-gatame (Scarf hold), etc.), Tori (Player executing technique) wraps an arm around Uke (Player receiving opponent's attack) neck from above and pulls Uke (Player receiving opponent's attack) body snugly against him while clasping one of Uke (Player receiving opponent's attack) arms between his legs. Tori (Player executing technique) then uses his lower leg to lift the upper part of Uke (Player receiving opponent's attack) leg, and applies pressure to Uke (Player receiving opponent's attack) elbow with the thigh of his other leg.
Other variations include twisting the arm behind the back. In actual competition, this Waza is often transitioned to from an Osae komi waza (Hold-down techniques) or a Katame waza (Grappling techniques).
