Nerve conduction studies, [12] especially of the pudendal nerve, may rule out more distal peripheral nerve lesions.

Somatosensory evoked potentials (SSEPs) [12] could be done as part of the workup to rule out multiple sclerosis, which could present initially as a lower spinal cord syndrome.

Duplex ultrasound of peripheral vessels may rule out compromised vasculature as a possible cause of associated claudication.

Lumbar puncture should be performed to examine the CSF to rule out inflammatory disease of the meninges or spinal cord.
