According to the Break Test scale, which grade indicates a strong contraction with pain, suggesting injury to a muscle or tendon?

• A. Strong and painful
• B. Weak and painless
• C. Strong and painless
• D. Weak and painful

Answer: (A)

A strong and painful contraction describes a situation where the muscle can generate near-normal force, but the resisted action elicits pain. This pattern points to an injury within the muscle or its tendon, such as a strain or tendinopathy, because the tissue still contracts forcefully yet is irritated or damaged. If the contraction were strong and painless, that would indicate normal strength. If it were weak and painless, weakness without pain would raise concern for a nerve or motor-pathway issue. If it were weak and painful, that would suggest more substantial pathology affecting both strength and causing pain. So the description of a strong contraction with pain best signals a muscle or tendon injury.
