Narrative:

Logbook had signed off 'flap asymmetry' on MFDU during taxi out. MFDU annunciated 'flap asymmetry' we cycled flaps to 8 degrees and it disappeared during descent into ewr we got 'flap asymmetry' on MFDU. Followed checklist procedure to a 'no flap landing' on 9300 ft (longest runway) 22L ewr with emergency equipment standing by. Advised 'a' flight attendant of potential problems, time remaining and emergency evacuate/evacuation signal. After very firm landing, caused by having copilot pull speed brake at 50 ft to dissipate extra plus 5K, a procedure suggested in flight manual. Taxied to gate. Upon disembarking 'C' flight attendant reported a sore shoulder after 20 mins in hotel room she desired to be checked out medically. I assisted her visit to a local hospital where she had xrays. The doctor diagnosed a sprained shoulder. Second doctor confirmed diagnosis next day. She returned with me to hotel. At around XA45 pm I called maintenance control and checked on aircraft repair and told them it was a hard landing. I had originally started to write this in the logbook but after discussion with copilot and mechanic decided it was not. Mechanic said they would check it out thoroughly. We flew ILS approach on autoplt/autothrottles until approximately 300 ft 84000 pounds vma 152-157 we held plus 5 till 50 ft. Recommended changes: do not use speed brakes until on ground (chief pilot confirmed that book would be changed to discourage such use. Lower flaps using alternate system should be an option since you can monitor visually and compare readouts on pfd. Advise copilot to call out deviations till touchdown. Write up hard landing. If have any questions (though since that time aircraft was confirmed to have no physical damage). Declare an emergency every time. Plainly (we did get equipment, give souls on board and fuel).
