Which assessment tool quantifies limb strength asymmetry for return-to-sport decisions?

• A. Dynamometry
• B. X-ray imaging
• C. Ultrasound
• D. Blood pressure cuff

Answer: (A)

Measuring how much force each limb can produce is key to spotting strength imbalances that influence return-to-sport decisions. A dynamometer gives a numeric measure of muscle strength, allowing you to test both limbs, compare the results directly, and compute an asymmetry index. This direct quantification lets clinicians decide if strength is sufficiently equal before clearing an athlete to return, and to track progress during rehabilitation. Imaging or cuff-based measures don’t assess how much force a muscle can generate. X-ray reveals bone structure, ultrasound shows soft-tissue appearance, and a blood pressure cuff assesses circulation, not muscle strength.
