Q. I have a participant who has problems with his right leg due to broken femur in 2000 which is now pinned and he also suffers with sciatica. He is having difficulty with some balance exercises due to this, so some are not being completed with this leg, I have said its fine and that he is to complete what he can and he is managing to do his strengthening exercises. Is that ok? A. As long as he is exercising safely and comfortably and not making any pain dramatically worse i.e. no more than we would expect with these exercises, then he can absolutely carry on with what he can manage.
