Narrative:

I executed a normal rotation for takeoff. As I continued to apply back-pressure to rotate into the command bars the elevator did not respond. I increased back-pressure; the control column moved back; but the elevator did not respond in kind. Approximately 100 ft AGL. Finally; the airplane 'jerked' nose-high. I released back-pressure to lower the angle of attack; it did not respond until it 'jerked' again. Controls became 'slushy' for the climb. By 500 ft AGL I was concerned about the elevator and made the decision to declare an emergency and return to the field. As we set up for the emergency landing; we briefed the flight attendant; completed the after landing checklist; in range checklist; and overweight landing checklist. We returned to the field. During the cruise and descent; the elevator functioned normally so we opted to do a precautionary landing rather than have the passengers brace. I opted to use as much nose up trim as I could to avoid reliance on the elevator for pitch control. We touched down uneventfully at less than 200 FPM descent.

Title: An EMB-145 returned to land after takeoff because the elevator control response on takeoff required a very large input to attain a takeoff attitude. An emergency was declared.
