Name Time Method 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.
