Kinetic oscillatory stimulation of nasal mucosa in non-allergic rhinitis: comparison of patient self-administration and caregiver administration regarding pain and treatment effect. A randomized clinical trial.

Conclusion: Patient self-administration of the Kinetic Oscillatory Stimulation (KOS)-catheter was a fully acceptable alternative to insertion of the catheter by physician with helmet fixation, in patients with non-allergic rhinitis (NAR). The approaches were equivalent regarding pain. The treatment effect in the patient self-administration group was not inferior.
