Dear Mario,

I believe that your chances to get a result are better if you go directly to a physiotherapist and make an interview with him/her.

Kind regards

Hi Mario J. Roska

How are you, I hope you're well.

So, I read a paper with this topic, however, it's in Portuguese. I send the link.

Hope this help.

Hi Mario, this paper seems good after reading the abstract. Unfortunately is not in English. Whereas many author might want to cite the author
