Criteria: Table 17-2 Cervical Spine Regional Grid: Spine Impairments (564-566), Table 17-5 Adjustment Grid: Summary (575), Table 17-6 Functional History Adjustment: Spine (575), Table 17-7 Physical Examination Adjustment: Spine (576), Table 17-9 Clinical Studies Adjustment: Spine (581)
Accurately define diagnosis, including significance and consistency of clinical findings, presence of causally-related disk herniation(s), and/or alteration of motion segment integrity. Objectify the presence or absence of radiculopathy. Most ratings are for non-specific spinal pain. Need to discern if Class 0 or Class 1 assignment. Maximum impairment for Class 1 is 3% WPI. Assure accuracy of adjustment factors, net adjustment calculation, and grade modification. Figure 17-2 (561) summarizes findings. Note revisions provided in “Corrections and Clarifications” (AMA Press, August 2008) to the Spine Regional Grids.
