It varies from state to state, and practice to practice honestly.

They won't expect you to have a lot of technical knowledge, but will be glad that you have some. The trainer background will be a bonus. They will also likely expect you to clean treatment rooms and put hot packs or ice on people as the therapists indicate. In general you just do whatever the therapist asks you to do. But your exercise knowledge will give you a leg up, but they will likely expect you to follow the exercise programs they lay out, not create any on your own.

But it might be different in California!
