Air Stacking
Glossopharyngeal Breathing
Air Stacking was performed with the subject seated in his wheelchair using a manual resuscitation bag (LIFESAVER® model 5345, Hudson, Temecula, USA) connected to a corrugated tube with an internal diameter of 22 mm, a one-way valve and a pipette. The maximum capacity of the bag was 1600 mL. A chest physiotherapist insufflated the patient during the inspiratory phase, requesting that inspire as much air as possible
Glossopharyngeal Breathing was also performed with the subject seated in his wheelchair and performing successive maneuvers of "swallowing air" until the maximum volume achieve was maintained. Then, the patient was instructed to breathe through ventilometer to register the MIC. Three measurements for each of the techniques were performed, and the highest reading was recorded. A difference of <10% between the measurements was used as the repeatability criterion
