Hi!
i agree with you about the 4 grade... mobilization is enought for now,even if training in how to find the barrier is a correct way to improve my finger sensibility...i think!
I'm doing my master in Italy,in a city of the north called Padova. Have you ever been in Italy? It lasts 2 years, and allowed to get OMT...Orthopaedic Manipulative Therapist what i attempt to do!
Ciao
