Weight bearing on hands after surgery

Hi everyone! So in February I had surgery on my thumb/wrist. Had a basal joint arthroplasty, which is where they basically remove a bone from your wrist and put in a suture to keep thumb from floating off somewhere. I'm healing OK, but they tell me it could be a full year before I'm 100%. And then I'll probably do the other hand. In the past year I've started practicing Kuk Sool Won, which is a Korean martial art. Part of the falling techniques involve putting full weight on hands - such as cat rolls and cartwheels. I cannot do these. I have stiffness and weakness in my right wrist still. OT Larry tells me to just take is slowly so as not to cause pain - he says I can't damage the joint. Even before surgery I'd not been able to do the cartwheels. I thought it was like riding a bike, and you just could always do them, but apparently somewhere between 12 and 50 I lost this skill. Was curious if anyone has suggestions on how best to increase strength and flexibility in my wrist, and also how do you all track things like martial arts? I can't decide if it's cardio or strength. Here's me at my yellow belt test.
