Sode guruma jime (袖車絞め) ("sleeve wheel constriction") is a type of Judo chokehold (shime-waza), which compresses the opponent’s trachea or the carotid arteries.
The technique can be executed from a variety of positions, but is generally performed by wrapping one arm behind the opponent’s head and grasping onto the sleeve of the gi with the opposite hand.
Since the choke relies on the leverage created by the gripping of a sleeve, it must be altered slightly to be performed without a gi.
The choke became associated with the judoka Ezequiel Paraguassu from the time he spent at Carlson Gracie’s gym in Copacabana, Rio de Janeiro in 1988 while preparing for the 1988 Olympics in South Korea.
Growing increasingly frustrated he decided to use the judo technique and managed to submit a number of his opponents.
