Narrative:
When attempted flight control check while taxiing for takeoff I was unable to move rudder pedals. First officer's pedals wouldn't move either, nosewheel steering tiller worked normal. We returned to gate. Aircraft had been released from a 'C' check the evening before. The rudder by-pass valve had been mechanically closed at the rudder during the 'C' check and somehow was never reopened, so we had no indication in flight deck.
