Assessments:

Functional NeuroPhysiological Assessment- In this test, you will be lying down and asked to perform several movements. We will paste sensors to your skin to record the electrical activity of your arm and leg muscles. Muscles recorded will be in your arms, trunk, legs, neck or a combination. Lower limb reflexes will also be performed. This test will last approximately 2 hours.

SomatoSensory Evoked Potentials- We will apply an electrical current over the skin around your ankles and wrist. We will ask you to wear a cap (similar to swim cap) with electrodes that record the electrical activity of your brain during the stimulation. This test will take approximately ninety (90) minutes to perform.

Sympathetic Skin Response- We will test the amount of sweat in your hands and feet after providing a low level of electrical stimulation over one of the nerves in your arm, forehead, and leg. This test will take approximately 1 hour to perform

Transcranial Magnetic Stimulation, Ulnar, Galvanic Vestibular Stimulation, and Acoustic Startle Response Stim- A low level of electrical stimulation will be used over the nerves of your neck, arms, legs, and/or back to measure how your leg muscles respond to the stimulation during standing and also during resting conditions. A pad will be pasted over the skin of your neck, arms, legs, and/or back and a small current will pass through it. For some tests, you will hear a loud sound, it might take you by surprise and we will measure how your leg muscles respond to your reaction to the sound. For some tests, we will magnetically stimulate your brain and we will measure how your leg muscles respond to the stimulation of your brain. We may use a combination of different stimulations on your brain, neck, arms, back and/or legs. Each test will take approximately 2-3 hours to perform.

Cord MRI- You will be asked to lie quietly on a table while images are taken of your spinal cord and your muscles. This test will take approximately 1 hour to perform.
