Pain (such as electrocution during torture and hunting. In this, the bear trap) is what prevents werewolves from shifitng. But when a werewolf shifts (Isaac was forced to transform because Scott used his newfound alpha ability to make him shift) he/she is supposed to be much stronger then he/she was when in human form.

"What's the common denominator? Pain, pain is what makes you human. Maybe you will survive...."- Derek talking to Scott about control in S1

"Pain makes you human"- Scott to Styles in "Anchors" after trying to prevent himself from going out of control/transforming.

Hope I helped and didn't make it hard to understand!
