What does a Break Test primarily measure?

• A. Isometric strength
• B. Dynamic strength
• C. Endurance
• D. Flexibility

Answer: (A)

The main idea being tested is the muscle’s isometric strength as measured by a break test. In a break test, the patient holds a position against the examiner’s applied force, and the examiner gradually increases the resistance until the patient can no longer hold and the limb begins to move. The resistance level just before the break reflects the muscle’s maximal isometric force at that joint position. This is different from dynamic strength, which requires movement through a range with resistance; endurance, which looks at how long a contraction can be sustained; and flexibility, which concerns the range of motion and tissue stretch rather than peak force. So the break test is best described as measuring isometric strength.
