For scoliosis, it's usually the standard PES B.
Unless you have, for example, slipped discs (or any other spinal
problem) and have gone thru X-ray/ CT/ MRI
scan to prove it so as to support the case, then it's
within PES C range.

As usual, the layman term of
"No specialist memo, no talk" applies.
Depends on the degree of severity. I seen one at medical centre
quite serious the elbows are uneven the back twisted. PES C or E
for that, I believed.
