Which breathing technique involves lying supine with a book placed on the abdomen to observe diaphragmatic movement?

• A. Lie supine, place book over the abdomen, observing the book rise and fall with diaphragmatic breathing
• B. Sit upright with shoulders elevated
• C. Use chest muscles to breathe
• D. Rapid, shallow breaths

Answer: (A)

The technique tests how well a person can use diaphragmatic breathing and how to observe that movement. Lying on the back with a book placed on the abdomen creates a simple visual feedback system: when the diaphragm descends during inhalation, the abdomen should rise and the book moves up; during exhalation the abdomen falls and the book lowers. This setup helps ensure the breath is driven by the diaphragm rather than the chest muscles, promoting more efficient ventilation and relaxation of accessory muscles. The other options describe different postures or breathing patterns that don’t specifically assess or promote diaphragmatic movement: sitting up with shoulders elevated tends to encourage upper chest breathing; using chest muscles to breathe is chest-dominant breathing; rapid, shallow breaths reflect poor diaphragmatic engagement and control.
