The primary outcomes were patient adherence to therapy after four treatments minutes used 60 minutes prescribed and satisfaction. Secondary outcomes included change in Borg dyspnea score 1 unit indicates a clinically significant change spontaneously expectorated sputum volume and forced expired volume in 1 second. Results Fifty-two participants were randomized to active n 25 or sham n 27 treatment. Patient adherence was similarly high in both groups 91 vs. 93 p . Patient satisfaction was also similarly high in both groups. After four treatments a higher proportion of patients in the active treatment group had a clinically significant improvement in dyspnea vs. p .
