this is in the ‘personal advice’ column. I have worked with only one client in that category (and it also included mental problems), thus I am not sure how much you can extrapolate to others.
It seems that the training was in the ‘I am doing something right and good’ spectrum of the rehabilitation as it was in an environment which is usually associated with health and fitness. The training itself was kept very predictable for the client. I felt that frequent change would have been unsettling. Progress was slow, and there were setbacks. I was surprised by the lack of core stability which was difficult to improve. I used a lot more stable exercises than I would for other clients.
You are welcome to contact me off the forum if you feel that I can be of assistance.
