A student pilot depressed the wrong rudder pedal and lost control of the PA-44 on a simulated engine failure prior to V1 takeoff. The instructor pilot was unable to regain control prior to exiting the runway surface. Some damage was incurred; including a prop strike; as the aircraft was returned to the runway.

Narrative:
At the hold short line for the runway we briefed the procedure for failure of engine prior to rotation; throttle to idle; maintain directional control with rudder and brake pressure. As we back taxied I continued with oral quizzing on which rudder to apply after the loss of an engine. He responded correctly. We turned around beyond the displaced threshold and were facing down the runway. I announced on CTAF that we would be momentarily delayed on the runway. I readied myself at the mixtures and on the rudder pedals the student applied full power; I cut the left mixture; the plane veered to the left. I felt the left rudder depress and I cut both engine mixtures and applied corrective right rudder and brake. The aircraft veered off the runway onto the muddy surface to the left. The left engine died at this point from the mixture being pulled. Just as the aircraft's right main left the runway surface I regained aircraft control and got it back on the runway. As we came back onto the runway I looked down and saw that I had not completely pulled right mixture to idle cut off; it still had approximately 30% travel left and the student had failed to completely close the throttles. As we re-entered the runway the nose gear struck the edge of the runway causing internal structural damage to the nose gear support. The difference in height of the runway and the muddy conditions of the area to the left of the runway caused the propeller to impact the ground. Corrective actions that could have avoided this would be completely pulling the mixtures to idle cut off; more corrective action on the rudder; allowing the plane to come to rest in the mud and not forcing it back onto the runway; the student pressing the correct rudder pedal; and closing the throttles completely.
