Primary Outcome Measures
NameTimeMethod
Mapping of diaphragmatic contractility by sonographic measurement of the thickening fraction (TF%) in the apposition zone of the diaphragm during palpation<br>- medioclavicular<br>- in the anterior, middle and posterior axillary line<br>- and medioscapular<br>with reference to the underlying etiology of the diaphragmatic dysfunction.
Secondary Outcome Measures
NameTimeMethod
Comparison between the affected side of the diaphragm and the healthy side of the diaphragm<br>- Sonographic mapping of the diaphragmatic thickness in the above-mentioned positions with reference to the underlying etiology and the duration of the diaphragmatic dysfunction<br>- Magnetic resonance imaging mapping of denervation edema in the muscular parts of the diaphragm as a correlate of an axonal lesion of parts of the respective phrenic nerve in a subgroup of subjects with onset of symptoms <= 3 months earlier
