Useful neuronal studies include the following:
- Needle electromyography, which can help diagnose lumbosacral radiculopathy with axonal loss.
- Nerve conduction studies, which can help differentiate lumbar spinal stenosis (LSS) from other confounding neuropathic conditions (e.g., lumbosacral plexopathy, generalized peripheral neuropathy, tarsal tunnel syndrome, other mononeuropathies);
- Somatosensory evoked potentials, which are useful in the diagnosis of central nervous system(CNS) pathology and are also used intraoperatively during decompressive surgery to assist the physician in dynamically identifying any iatrogenic changes to the sensory pathways.
