With the arms supported,the accessory breathing muscles can act on the rib cage and the thorax,allowing more expansion for inspiration.When the patient leans forward on supported hands,the intra-abdominal pressure rises and thus pushes the diaphragm up in a lengthened position.The improved length-tension relationship (optimal muscle length)provides the diaphragm an increased strength of contraction.
