This technique can be practiced using different stances and whilst stepping in different directions. In the most basic format it can be practiced whilst standing still, as shown here. The chief principle embodied in the downward sweep is one of pulling and pushing: one hand pulls up and back towards the hip while the other hand pushes down and forwards.

Bridging
The downward sweep is used simply to sweep the attacker away to one side. First one arm moves across to intercept the incoming limb. Next the other arm comes down and sweeps the limb away.

Note how the defender moves 'offline', making it easier to counter-attack and more difficult for the attacker to follow through with another strike.

Striking
One arm pulls on the attacker’s wrist whilst the other strikes a vital point (or kyusho)on the arm, in order to unbalance the attacker.

Joint-locking
The downward sweep is used to apply an arm-bar (which puts pressure on the elbow joint – the assailant must either bend down or have their elbow dislocated). One hand pulls the assailant’s wrist to the hip, the other arm pushes down on the assailant’s upper arm (the triceps tendon just above the elbow).

Note: In this example the downward sweep is followed by a strike.

Throwing
Having been grabbed and pulled the defender goes with the pull, stepping behind the attacker’s leg. One hand grabs the clothing, leg or groin and pulls up while the other presses across and down on the assailant’s torso in order to knock them down.

Choking
From a clinch position one hand grabs the assailant’s lapel in preparation for the choke to follow. The defender adjusts their position to get behind the assailant and unbalance them. From here the defender simply presses down on the neck with one hand and pulls the lapel up and back with the other, in order to apply the choke.
