For me and with my not being able to use The Vest without causing pain I started doing my own clapping percussion on myself.
I go on the sides of the breastbone. I do it during my morning therapy and often as I go along in my day....do it during the day.
I also go on the sides of my backbone and now I am doing more area of my back/lungs than I had been doing before. Making sure I do the clapping percussion somewhat to the side of my back just above my waist. With what I have been doing in total, within the years time of doing it all the CScan showed improvement in upper lobes and less inflammation, however, new concern in lower left lobe. So hopefully, I am doing what I believe will do the trick...we shall see...by my working around the area where I believe the lower lobes are.....with the clapping percussion there and than to the upper part of my back.
I may start again, as well, with The Vest on the lower settings to try to add to it all at another time of day.
As I said, this is what I do for me. It's not something suggested by the pulmonologists it is strictly my choice and as long as I can do it and continue to feel well and see improvement I will be happy.
Hope this doesn't ruffle anyone's feathers so to speak.. As I said no pulmonologist has suggested this clapping percussion. If I couldn't use the vest I had to try something different.
