You need to find out what pins, if any, are not being used by the shield. Then get yourself a proto shield. This will go between the arduino and your motor shield and allow you to wire in whatever other sensors you need to the unused pins of the arduino.

If there are no unused pins then you may want to upgrade to an Arduino Mega.
