Got any tips on physiotherapy in the renal specialty for my 1st year placement?

Hello,
I've just finished my first year studying physiotherapy at Kings College and have been placed in the renal department at Guy's Hospital for 6 weeks as part of the course. I imagine that physiotherapy might be used to maintain mobility and strength in patients with kidney failure and to optimise blood circulation after dialysis. However, I haven't been able to find any information online and was wondering if anyone could enlighten me. Any advice would be MUCH appreciated.

Cheers,
Adam
