Which device is used to support inspiratory training in this management approach?

• A. Goniometer
• B. Spirometer
• C. Dynamometer
• D. Treadmill

Answer: (B)

Focusing on training the muscles involved in inhalation relies on a tool that can quantify and provide feedback on breathing. A spirometer fits this role because it measures the volume and flow of air during inspiration, giving real-time data on inspiratory capacity and tidal volume. With a spirometer, therapists can set targets (for example, aiming to reach a specified inspiratory volume) and track progress over sessions, which guides and reinforces inspiratory training.

The other devices aren’t suited for this purpose: a goniometer measures joint angles, not breathing performance; a dynamometer assesses muscle strength in a limb (often the hands); and a treadmill is used for aerobic endurance, not for guiding inspiratory training.
