Grade III joint mobilization is used for which combination?

• A. Small, pain
• B. Large, pain
• C. Large, increase tissue mobility
• D. Small, increase tissue mobility

Answer: (C)

Grade III joint mobilization uses a large-amplitude motion that is applied up to the limit of the joint’s available motion. This approach is chosen to stretch and improve the mobility of periarticular tissues, helping to restore joint play when stiffness or tissue tightness limits ROM. It’s focused on increasing tissue mobility rather than solely reducing pain, which is more associated with smaller-amplitude movements at the start or mid-range. The other options describe movements aimed at pain relief or end-range control with small amplitudes, not the tissue-stretch goal of Grade III. So the combination that fits Grade III is a large-amplitude movement up to the end range to increase tissue mobility.
