Which of the following is NOT typically the result of overuse?

• A. Stress fracture
• B. Grade 3 joint sprain
• C. Tendinitis
• D. Microtraumatic injury

Answer: (B)

Overuse injuries come from repetitive submaximal loading and insufficient recovery, leading to microtrauma in bone, tendon, or other tissues. A stress fracture results from accumulated bone microdamage under repeated loading, tendinitis from repetitive tendon strain, and microtraumatic injuries from ongoing minor insults. A Grade 3 joint sprain, by contrast, is usually caused by a single acute event that ruptures ligaments and creates marked instability, not by gradual repetitive stress. So it’s not typically the result of overuse.
