Croft is credited with inventing " air packing " ( also known as " lung packing " or " glossopharyngeal inhalation " ), a method used to overfill the lungs, increasing the volume of air in the lungs above the total lung capacity prior to breath-holding.

The increased total lung capacity ( hyperinflation ) can result in the clinical feature of a " barrel chest "-a chest with a large front-to-back diameter that occurs in some individuals with COPD . Hyperinflation can also be seen on a chest x-ray as a flattening of the diaphragm.

For example, the intercostal muscles receive their innervation from T1 T11, and if any are damaged, more emphasis will need to be placed on the unaffected muscles which are innervated from higher levels of the CNS . As SCI patients suffer from reduced total lung capacity and tidal volume it is pertinent that physical therapists teach SCI patients accessory breathing techniques ( e . g . apical breathing, glossopharyngeal breathing, etc . ) that typically are not taught to healthy individuals.
