Narrative:

Performed receiving and before start checklists in entirety. Started left engine, then during right engine start aircraft began to roll forward. First officer called 'we're moving.' both he and I simultaneously applied brakes and aircraft came to an abrupt stop. Checked with purser if everyone was ok. He informed me that we had 1 flight attendant injured. Waited on the ramp for approximately 5 mins to make sure all was well. The purser advised me that flight attendant was knocked unconscious for approximately 30-40 seconds. He said that everyone, including injured flight attendant, was ready to continue on to destination. I monitored condition throughout flight and she told me her stomach felt upset and her pelvic area hurt badly. I used satcom and requested a doctor meet us at gate. Upon arrival, doctor recommended flight attendant go to hospital for further evaluation. One other flight attendant had a minor bruise. Before starting engines we were continually interrupted by load planner, military personnel, flight attendants, and countless messages from dispatch. Dispatch sent 3 or 4 duplicate messages each requiring immediate reply. We received no fewer than 10 weight and balances which constantly dumped our takeoff and performance data. Our final ATC clearance was significantly different than what we had loaded. The ground supervisor gave the clearance to start engines and I gave the brakes set signal. It is my belief that the constant distrs were a direct contributing factor in this incident.

BEFORE STARTING ENGS WE WERE CONTINUALLY INTERRUPTED BY LOAD PLANNER, MIL PERSONNEL, FLT ATTENDANTS, AND COUNTLESS MESSAGES FROM DISPATCH. DISPATCH SENT 3 OR 4 DUPLICATE MESSAGES EACH REQUIRING IMMEDIATE REPLY. WE RECEIVED NO FEWER THAN 10 WT AND BALS WHICH CONSTANTLY DUMPED OUR TKOF AND PERFORMANCE DATA. OUR FINAL ATC CLRNC WAS SIGNIFICANTLY DIFFERENT THAN WHAT WE HAD LOADED. THE GND SUPVR GAVE THE CLRNC TO START ENGS AND I GAVE THE BRAKES SET SIGNAL. IT IS MY BELIEF THAT THE CONSTANT DISTRS WERE A DIRECT CONTRIBUTING FACTOR IN THIS INCIDENT.
