Which of the following is NOT one of the seven tools for relieving pain?

• A. Immobilization
• B. Therapeutic Exercise
• C. Ultrasound
• D. Cryotherapy

Answer: (C)

The idea being tested is which methods are considered the basic, readily applied tools for reducing pain in common rehab practice. Immobilization, cryotherapy, and therapeutic exercise are among those practical, immediate measures that directly control pain and inflammation without needing specialized equipment. Ultrasound, while a valid rehab modality, is a more specialized device-based treatment aimed at influencing tissue healing rather than providing immediate, broad pain relief. Because of that, it isn’t counted as one of the seven foundational pain-relief tools in this framework. In other words, ultrasound can be valuable for certain rehab goals, but it isn’t part of the core set of simple pain-relief tools like immobilization, cryotherapy, and therapeutic exercise.
