Here, you may have some Greek feedback. In this country Schools are still teaching the "old" set of techniques and these are what students are using during their standard practice. However most of the veterans, base their approach in early mobilisation and in active breathing techniques. We prefer to have well trained patients who are trying to help themselves as much as they can.
Because we luck research so far, we do not have a general direction nor any official guidelines. Thus there are people how are only using the traditional respiratory battery of techniques.
