Summary Rationale: The diaphragm is a dome-shaped muscle which separates the thoracic cavity from the abdomen. In patients with diaphragm paralysis the treatment (surgery versus non-invasive ventilation) is based on physician preference, not sound scientific evidence. Clearly studies are needed to guide a scientific decision making. Objective: In this pilot study the we want to know the clinical relevant effect of both therapies on EQ-5D\_5L, the latter being the primary outcome. Finally, it will show the investigators the costs of both therapies form a societal perspective. Study design: open-label, multi center intervention pilot study Study population: 20 participants \>18 year and diagnosed with a unilateral diaphragm paralysis resulting from phrenic nerve injury. Intervention: 10 participants for surgical plication and 10 participants for nocturnal non-invasive ventilation while on the wating list for surgical plication. Main study parameters/endpoints: The goal of the pilot study is to describe the effect of both plication and NIV on the endpoints of the intended efficiency study. The intended primary endpoint is quality of life as measured by the EQ-5D-5L questionnaire. Secondary endpoints are; the Medical Research Council (MRC) dyspnoea scale, the Diaphragmatic Paralysis Questionnaire, Borg dyspnoea score, 6 minute walk test, spirometry in both sitting and supine position, a polysomnography and transcutaneous measurement of carbon dioxide an oxygen saturation at night.
