Somatosensory Evoked Potentials (SSEP)
This safe test evaluates the sensory pathway as an eletrical signal travels from teh nerve endings 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 stimulation. You may feel some discomfort and/or muscle twitch during the study. These results will be interpreted by a neurologist.
Approximately 15 minutes for each each nerve being tested (median, ulnar, tibial, peroneal) or 60 minutes for a Upper and Lower SSEP when performed together.
- Shampoo and dry hair without using sprays, gels or oils. No braids or intricate hair designes as they will need to be removed prior to the test.
