Can a therapist partake in physical work with a Client without informed consent?

This happened to me. He never told me the risks involved and I never signed anything. He did put down I requested most of it though. I feel I was vulnerable. He told me his supervisor had no concerns but my notes says he was ambivalent about it but justified it cos it was 'working'

NO!
My T uses a lot of touch with me, far more than most would and more than many feel is ethical. However, we talk about it a lot first and regularly afterwards. He might mention something he is willing to do as he knows that I am afraid to ask because of past experiences but that is it. I have to ask for it/initiate it every time. Usually I spend a whole session talking to him about what any new kind of touch will look like/feel like, what it means to me, what it means to him, when it’s OK, when it isn’t OK.... then we check in often about if we are both still comfortable with the touch and if the meaning has changed. We also talk about how specifically it benefits my therapy and helps me get to my goals. T has only touched me once without us discussing it first and he was very cautious, slowly reaching out to put his hand on mine and watching for even the slightest indication I might be uncomfortable. This happened when he knew he had triggered trauma from before I was old enough to talk. We processed it when adult me was back to normal.

I wrote him a letter that said there's no way I could have said no to him touching my shoulder.

We never discussed that.

I might ask for him to touch my shoulder but then he would start rubbing it and there was times it developed into more of a back rub.

I always referred it as him touching my shoulder in letters as that was true but not the whole truth. Will it look like I'm lying?

I never asked him to rub my shoulder or back.

I see a difference and that beyond placing his hand on my shoulder he should have waited for permission to rub it or my back.

I’m sorry you are having to go through this. In the case of a T IMO the burden of proof should be on him not you.
And yes, I see a difference between putting a hand on someone’s shoulder and rubbing their shoulder/back. My T will it his hand on my arm and one time he absent midedly rubbed my arm. He stopped and checked on me. That suggests to me that my T sees a difference in it as well.
