Methods: A randomized controlled pilot study was conducted over a period of 16
weeks, including 31 patients in the intervention-group using Resperate. A control
group of 22 patients only listened to music (CD) and used no other therapeutic
device. The exercises were accomplished over 15 minutes, three times a week in
both groups. Patients (n = 18) from both groups were interviewed about their perceptions
of the treatment.
