Demonstrate correct direct, indirect, and blunt percussion techniques used during the physical examination.
- Direct percussion is the direct tapping of a body part with one or two fingertips to elicit possible tenderness
- (e.g., tenderness over the sinuses).
- Indirect or mediate percussion is the most commonly used method of percussion. The tapping done with this type of percussion produces a sound or tone that varies with the density of underlying structures. As density increases,
- the sound of the tone becomes quieter.
- Blunt percussion is used to detect tenderness over organs (e.g., kidneys) by placing one hand flat on the body surface and using the fist of the other hand to strike the back of the hand flat on the body surface.
