> Simon Kruithof PTHi Simon, Joellen here, most of the info you gave I already knew from
my A&P classes in nursing school. I do have one question though, they
had to do a muscle flap after surgury for a bad decube early on (had the
wrong cushion for my chair) they disconnected one of the muscles in my
right thigh and folded it in half to fill in the space, question is this
how will this affect my attempts to stand and do you think I should do
any specific exercises to compensate for this. I'll ask my pt therapist
on Friday but would also appreciate your take on this. Thanks!
