Erj-175 captain reported they found the flight controls were locked in all axes after disconnecting ...

Narrative:

During approach turned off the autopilot; the switch worked properly and heard the aural 'autopilot ' warning. Attempted to move the yoke but it was locked up on all axes; the first officer tried his side and was locked as well. We had no indications on EICAS and and no other abnormal indications. I tried to introduce some power and back pressure to see if I could keep the plane in the air and didn't like the response. With low fuel and no flight controls; trying an autopilot go-around seemed like a very poor idea so I had the first officer come up on the controls and together we broke free whatever was stuck. Later learned I had to apply significant lbs of force to break it free. I recovered the aircraft and landed without incident.
