Brief Summary
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.

Eligibility Criteria
You may qualify if:
- \>18 years
- diagnosed with a unilateral diaphragm paralysis based on isolated phrenic nerve injury.
- Unilateral diaphragm paralysis is defined as follows: complaints of dyspnea and / or orthopnea combined with a drop in VC of more than 15% when change from upright to supine position and a positive sniff test during fluoroscopy or ultrasonography. A positive sniff test means that the diaphragm stands still or even moves in cranial direction (paradoxical movement ) during the sniff inspiratory maneuver.
- Ability to provide written consent
- Time between diagnosis and treatment should be at least 1 year
You may not qualify if:
- Patients diagnosed with a bilateral diaphragm paralysis.
- A diaphragm paralysis in combination with a more systemic neurological or neuromuscular disorder like for example Amyotrophic Lateral Sclerosis ,
- Hypercapnia during daytime (PaCO2 \> 6.0 kPa)
- Radiotherapy of the thorax
- Contra indication for diaphragm surgery.
