Expression pedals can be used to control how much (from 0-100%) an effect has on your sound. It typically allows you to alter some specific parameter (how much modulation, delay, gain, etc.) on the fly. But the effects pedal or unit has to have the built in ability to have an expression pedal built in.
For example, think of a volume pedal but that controls not the volume, but the amount of an effect.
