How are strains and sprains differentiated on the field?

• A. Strain involves ligament injury with swelling and joint laxity; Sprain involves muscle/tendon injury with localized tenderness.
• B. Strain involves muscle/tendon injury with localized muscle tenderness; Sprain involves ligament injury with swelling and joint laxity.
• C. Strain is a nerve injury; Sprain is a bone fracture.
• D. Strain and Sprain are both nerve injuries.

Answer: (B)

The key idea is identifying which tissue is injured: muscle/tendon versus ligament. On the field, you’ll see strain signs as pain concentrated in the muscle or its tendon, with localized tenderness and sometimes weakness when the muscle is used. Sprains show injury to a ligament, so the joint area tends to swell and may feel unstable or “loose” when the joint is tested or stressed. In practical terms, if the pain and tenderness are centered in a muscle region and the joint isn’t loose, it’s more consistent with a strain. If swelling is present around a joint and the joint shows laxity or instability, a sprain is more likely.
