Hi - Just wondering how many use the accapella (sp?) as a form of their treatment? Do you use it with the vest and manual PT or do you use it by itself. My son (7) had the manual cpt until 2 and then the vest. Now he prefers the accapella. It def. seems to be more productive than the others for him. I am sure that a combination of the acappela and one of the others would be best. Just looking for your experiences and thoughts. Thanks. Jo Ann
