|---|---|
| 10% | Greater than 60° but not greater than 85°, or muscle spasm or guarding not causing abnormal gait |
| 20% | Greater than 30° but not greater than 60°, or spasm or guarding causing abnormal gait or spinal contour |
| 40% | 30° or less, or favorable ankylosis of the entire thoracolumbar spine |
| 50% | Unfavorable ankylosis of the entire thoracolumbar spine |
| 100% | Unfavorable ankylosis of the entire spine |
Cervical (neck) criteria, summarized
| Rating | Key criteria (forward flexion) |
|---|---|
| 10% | Greater than 30° but not greater than 40° |
| 20% | Greater than 15° but not greater than 30° |
| 30% | 15° or less, or favorable ankylosis of the entire cervical spine |

Combined range of motion also counts at some levels. Intervertebral disc syndrome can alternatively be rated on incapacitating episodes requiring physician-prescribed bed rest.
Don't miss these
- Radiculopathy: Nerve pain, numbness, or weakness in the arms or legs is rated separately for each extremity.
- Pain and flare-ups: Examiners should test where pain begins and estimate additional loss of motion during flare-ups and repeated use. Describe your flare-ups clearly.
- Secondary conditions: Altered gait can affect the hips and knees.
