Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to investigate the impact of unilateral or bilateral diaphragm plication in a prospective randomised controlled way on symptoms, pulmonary function including gas exchange, respiratory muscle strength, exercise capacity and breathing during sleep in patients with proven uni- or bilateral phrenic nerve paralysis present for at least 1 year without any evidence of spontaneous recovery.
