I do not know whether any physio dislikes the respiratory physiotherapy or not? It could be due to personal preference or an aptitude of physiotherapist or the dislikeness could be due to the ignorance and lack of knowledge in the respiratory physiotherapy. Infact, respiratory physiotherapy in my personal experience is very easy, informative and one in which you may see the results of your techniques at the bed side of patients. So a easy and very demanding job for physios. It is just some perosnal views as I have no idea the others would agree or not with me.
