Pinpointing Nerve Problems
On-site Electrodiagnostic Medicine Delivers
Accuracy And Convenience For Patients

The field of electrodiagnostic medicine offers effective testing options for determining the cause of muscle and nerve problems. Carolina Neurosurgery & Spine Associates utilizes these tests, along with a full array of additional on-site diagnostic services, to provide greater convenience for patients.

“We not only offer electrodiagnostic studies, but also a wide array of imaging studies, and even neuromuscular ultrasound, all in one practice,” said practice physiatrist Sameer Vemuri, M.D. “Once a problem is diagnosed, we don’t have to refer patients outside the practice for treatment. Comprehensive non-surgical and surgical options are readily available from our team of well-qualified physiatrists, neurosurgeons and physical therapists.”

Dr. Vemuri completed a Neuromuscular/Electrodiagnostic Medicine Fellowship in the Department of Neurology at Tufts-New England Medical Center in Boston.

The two primary electrodiagnostic studies utilized by Carolina Neurosurgery & Spine Associates are Nerve Conduction Studies (NCS) and Electromyograms (EMG).

Nerve Conduction Studies (NCS)
Nerve conduction studies measure how well and how fast the nerves can send electrical signals. These tests help detect damage to the peripheral nervous system, which includes all of the nerves that lead away from the brain and spinal cord, and the smaller nerves that branch out from those nerves. An NCS is often used to help diagnose nerve disorders, such as carpal tunnel syndrome or Guillain-Barré syndrome.

Electromyograms (EMG)
An EMG measures the electrical activity of muscles at rest and during contraction. This test is performed to help localize the cause that damages muscle tissue, nerves, or neuromuscular junctions. These disorders can range from herniated disc/radiculopathies to amyotrophic lateral sclerosis (ALS). An EMG can also help find the cause of weakness, paralysis, or muscle twitching, as well as more proximal disease processes in the peripheral nervous system. Unlike motor nerve conduction studies, which evaluate a whole population of motor axons and muscle fibers, electromyography allows for evaluation of individual motor units.

“Electrodiagnostic studies are effective and useful clinical adjuncts to help us pinpoint the cause of a patient’s neurological symptoms, as well as rule out certain conditions,” said Dr. Vemuri.
