This article explains this better. Similar to a cervical collar in a way. Helps to maintain proper posture so the damaged neck/shoulder soft tissues can heal better. At the place I'm going to go to they do some mobilization massage work, cross fiber and whatnot, posture correction analysis and remediation, then tape your shoulders and neck so your posture can be better. I guess in such a way that it is uncomfortable when you move into positions of poor posture; rounded shoulders and slouching.
