from Table 3.5.1 in Part 3.5. These values are to be used in arriving at the fractional loss of range of movement when the actual movements of a joint are known in degrees.

If non-accepted conditions contribute to the loss of range of movement, Chapter 19 (Partially Contributing Impairment) is to be applied in conjunction with Table 3.1.1.

For the purposes of this chapter:
"position of function" means the position that interferes least with the total  function of the limb or the spine; and
"unfavourable position" means a position that is significantly different from the position of function; and
"flail joint" means a joint that is completely unstable in all directions.
