“…Diaphragm excursion amplitude (DE a ) was collected in 58% of articles, and diaphragm excursion velocity (DE v ) was collected in three articles. With regards pulmonary parameters, the investigators mainly used parameters such as MIP (48% of articles) [7, 10-12, 14, 20, 24, 26, 28, 31, 34, 36, 37, 39, 40], FVC (45% of articles) [4, 7, 10-12, 14, 20, 25, 27, 32, 33, 35, 40, 41] and FEV 1 (32% of articles) [4, 7, 11, 12, 23, 29, 32, 33, 35, 41].…”
