Services

The WellSpan Neurophysiology Laboratory, located at York Hospital, offers a variety of neurodiagnostic tests. The lab is staffed by a team of experienced neurologists and neurodiagnostic technicians who work with patients and physicians to provide high-quality care. 

The following tests are available through the laboratory:

• Electroencephalograms (EEG) 
  Electroencephalograms record the electrical activity on the surface of the brain. This painless test is used to help diagnose a seizure disorder, to look for causes of confusion or evaluate many other conditions that affect the brain.
• Nerve Conduction (NCS)/Electromyography (EMG)
  NCS/EMG studies are usually ordered for problems with the nerve or muscles. Measuring the electrical activity in muscles and nerves can help detect diseases that can damage muscle tissue or nerves.  The tests are done separately, the NCS is done first followed by the EMG. The NCS measures how fast an impulse travels through a nerve. The EMG measures the health of the muscles and the nerves that control the muscles.
• Evoked Potential Tests
  Evoked Potential Tests (EP) is a diagnostic tool used to look for disease or damage to the central nervous system. The test will detect if there is a "block" in the nervous system that effects how the brain responds to an electrical impulse from the nerves. There are three types of EP tests: Brainstem Auditory Evoked Response (BAER),Visual Evoked Response (VER) and Somatosensory Evoked Response (SSER). The tests can be ordered individually or as a group, depending on the diagnosis. In all cases, the tests are non-invasive (meaning the skin is not punctured). All electrodes sit on the surface of the skin.
  • Brainstem Auditory Evoked Response (BAER)
    Brainstem auditory evoked potential evaluates how the nervous system, specifically the brainstem, responds to specific sounds. BAER tests are used to evaluate complaints of dizziness, ringing in the ear, vertigo and hearing loss.
  • Visual Evoked Response (VER)
    Visual evoked potentials evaluate the visual nervous system from the eye to the brain. Visual evoked potentials are used to evaluate problems with the optic nerve.
  • Somatosensory Evoked Response (SSER)
    Somatosensory evoked potential is a test that is used to evaluate complaints of pain, weakness, numbness and tingling in the arms or legs.  SSER's use small electrical pulses to test the pathways between the peripheral nerves, spine and brain.
