Thanks,
but what is your clinical reasoning for that?

In the case of a sciatica the syptoms are peripheral but on assessment there will be a positive SLR/slump test. In sciatica the cause of pain is clear.
I do agree that cervical/thoracic treatment is important but if ULTT is negative and symptoms appear to be local (pain on palpation, resisted etc) what is the clinical reasoning for using it as a primary treatment??
