Narrative:

We did a 1 person pushback at miami. After pushing back, pushback driver instructed me to set parking brake. I was just pushing down on the brakes, and about to set the parking brake handle, when the aircraft was abruptly moved against the force of the brakes. I immediately called the pushback driver on flight intercom to see what had happened. He asked me if the brakes were set, and I responded that I was about to set them, as he had asked me to. He replied to me that he did not instruct me to set the brakes, but to start the engines. We did not have any more discussion of whether he had said or hadn't said to set the brakes. At this point, I called the purser to find out if our in-flight crew as alright. She checked with all the crew (5 flight attendants) and 3 had been hurt. We were prepared to return to the gate, to have the crew checked, but they did not feel that they needed this. A maintenance supervisor came out to check the nosewheel area while we started our engines. Everything appeared normal, and we had driver disconnect headset. Taxi out and rest of flight were normal. All flight attendants were able to accomplish their duties on the flight to lax. We asked to have an in-flight supervisor meet the flight on arrival in lax.
