Somatosensory Evoked Potentials (SSEP)

This safe test evaluates the sensory pathway from the nerves in the arms and/or legs to the brain. This test evaluates whether there is an interruption somewhere along the pathway. Tiny electrodes will be placed on your head and other areas of your body such as your neck, lower back, arms and legs. You will feel a mild electrical "pulse" for up to several minutes in each limb that is being evaluated. A computer will record the results as the nerves in your limbs, spinal cord, and brain respond to the pulse. You may feel some discomfort and/or muscle twitch from the pulse. These results will be interpreted by a neurologist.

Time:                                                                                                                                              60 minutes for each nerve being tested (Median, ulnar, Tibial, Peroneal).


  • Wear comfortable, loose-fitting clothing, such as a sweatsuit
  • Bathe without using lotions
  • Shampoo and dry hair without using sprays and/or gels
  • Continue normal diet and medications (bring a list of your medications)
