This session will focus on 1) understanding the role, timing, and limitations of electrodiagnostics, tests for small fiber dysfunction, and tests for immune mediated neuropathic pain; 2) when non-routine spine imaging may be preferable or complementary to routine spine MRI; 3) an approach to uncertain spine MRI findings.
Neuropathic Pain Diagnostic Modalities
James C. Watson, MD
Spine Imaging: When MRI Is Not Enough
Felix E. Diehn, MD
- Explain the role and limitations of electrodiagnostic testing in the evaluation of neuropathic pain conditions.
- Interpret the unique, but now widely available studies available to evaluate small fiber nerve dysfunction (sudomotor testing and epidermal nerve fiber density testing through skin biopsy) and immune mediated neuropathic pain syndromes (voltage gated potassium channel, LGI1 and CASPR2 antibodies).
- Distinguish when non-routine imaging may be preferable or complementary to routine spine MRI.
- Define a practical approach to uncertain spine MRI findings in a pain medicine practice.
