Spinal Region—When Two or More Ranges of Motion Are Involved
|
|
a.
|
Calculate separately and record impairment contributed by ankylosis in each position of the spinal region.
|
|
b.
|
The largest ankylosis impairment value is the impairment of the whole person contributed by spinal region.
|
|
|
Impairment of the Whole Person
|
Example: Cervical Region ankylosed at:
|
20 degrees FLEXION
|
= 33%
|
|
10 degrees RIGHT ROTATION
|
= 27%
|
The largest ankylosis impairment value is 33%; therefore, the whole person is 33% impaired by ankylosed cervical region.
