On the joint integrity scale, which score corresponds to normal motion?

• A. 0
• B. 6
• C. 5
• D. 3

Answer: (D)

The joint integrity scale rates how well a joint moves, from impaired to abnormal motion. Normal motion is represented by a mid-range score, specifically a 3 in this framework. That means the joint moves with full, smooth, pain-free range and stable mechanics. Scores lower than 3 reflect increasing impairment or restriction, while scores higher than 3 indicate movements that are outside normal (such as excessive or unstable motion). So a score of 3 best matches normal motion, making it the correct choice.
