Manual techniques. (A) Cupped hand used for “clapping” chest physiotherapy to help disrupt airway mucus. This “cupping-and-clapping” technique can be performed with one or both hands and is applied relatively rapidly to the chest wall in a patient who is supine, prone, sitting up, or in another position. (B) Position of the hand used for the shaking technique (the larger movements depicted by the longer double-arrow) or (C) the vibrating technique (the smaller movements depicted by the shorter double-arrow) typically performed on and parallel to the chest wall. The orientation of the hand depicted is for shaking or vibrating the chest wall in a patient who is sitting upright.
