| Ilioinguinal nerve injury | 1.4 | 0.7 | 1.05 |
| Trigeminal neuralgia* | – | 1.4 | 0.70 |
| NP nonspecified/rare syndrome† (less than 1% for each) | 12.5 | 18.9 | 15.68 |
| Total | 100.0 | 100.0 | 100.00 |
*
Trigeminal neuralgia is listed specifically to emphasize how rare it is in our clinic (multiple sclerosis in this cohort is also below 1%).
†
Examples of rare syndromes are Friedreich’s ataxia, Charcot-Marie-Tooth disease, diabetic NP cachexia, etc; an example of a nonspecified NP syndrome is diffuse arm pain with patches of altered sensation after electrocution
