Sudden snagging at 50% of the way through the ROM during flexion and extension, always with minimal resistance when the ROM is continued to the end Grade Ⅱ More pronounced increase in muscle tone, with a more pronounced increase in resistance through most of the ROM, but the affected part is still able to move with relative ease Grade Ⅲ Severe increase in muscle tone, with difficulty in performing a PROM Grade Ⅳ Stiffness, with inability of the affected part to flex and extend
