Isometric Exercises?!

Question: Hi. I messed up my shoulder and my doctor told me to strengthen it with isometric exercises. Ive found a bunch on this site:

please take a look at it and tell me if i am supposed to exert force when doing these exercises or if i should just calmly do it without any force at all. I'm not sure, but i think i should use force because using no force doesnt give me any pain at all. Also, will this heal the muscle in my shoulder?

My mom has told me about Isometric exercises and she was told that regarding them you hold the position for several minutes instead of constant movement. I would recommend calling your physical therapist back to ask for further clarification of the instructions on these exercises.
