These tests enable physicians to more precisely evaluate and localize neurological impairment. They also help determine a prognosis for recovery, and establish realizable treatment goals.

The Electrodiagnostic Center comprises two highly sophisticated laboratories–the Brain Electrophysiology Laboratory and the Electromyography Laboratory. Both provide a thorough complement of tests that aid physicians in the study and treatment of neurophysiologic abnormalities.

Brain Electrophysiology Laboratory

This laboratory provides a variety of non-invasive studies of the central nervous system, including sensory evoked potentials.

Sensory Evoked Potentials

This battery of tests analyzes the cranial nerves, spinal cord and brain. They check the continuity and quality of conduction through central nervous system pathways to determine which pathways are open and functioning normally and which are impaired. They diagnose nervous system disorders, locate sites of nerve damage and evaluate a patient’s condition after treatment or surgery.

Three major types of stimulation are used, each assessing a different sensory pathway through the nervous system: visual, auditory, and somatosensory. Visual stimulation checks the nerve pathways from the eye to the brain; auditory, from the ear to the brain; and somatosensory from the upper and lower limbs to the brain.

Electromyography Laboratory

This laboratory provides comprehensive testing of peripheral nerves and muscles for patients with suspected neuromuscular disorders. Studies performed here include:

• Electromyography (EMG)
  EMG analyzes the electrical activity recorded from muscles. Nerve and muscle diseases reveal themselves in specific electrical patterns and EMG detects these patterns.
• Nerve Conduction Studies (NCS)
  These tests evaluate the health of the peripheral nerves by recording how fast an electrical impulse travels through them. Slower impulse speeds can indicate the presence of nervous system disease or injury. A loss of amplitude of sensory or motor responses can indicate a failure of nerve fibers to conduct impulses or a reduced number of nerve fibers available in the nerve. These studies are especially helpful with patients who have post-polio syndrome, radiculopathy, neuropathy, myopathy, carpal tunnel syndrome and other nerve entrapments, neuromusculoskeletal injuries, and other neuromuscular disorders.

A Partnership with the Referring Physician

All diagnostic studies are conducted by specially trained and board-certified physicians and technologists. Study results are sent to the referring physician along with treatment and evaluation recommendations when appropriate. Physicians may choose to refer their patients to MossRehab for treatment, or they may simply use the Electrodiagnostic Center as an independent service. Referring physicians are invited to visit or call the center to discuss their patients’ study results.
