Mohamed H. Sadiq, MD

Tanner Clinic is pleased to have on its staff a board-certified neurologist who is fellowship-trained in clinical neurophysiology, a specialty of analyzing nerve and muscle disorders using bioelectric tests.

Based at Tanner Clinic Layton, Dr. Sadiq’s practice covers all aspects of nerve and brain disorders, such as multiple sclerosis and headaches.

He also received specialized training in conducting electromyographic (EMG) testing and nerve conduction studies (NCS) to diagnose nerve and muscle disorders. More importantly, he is skilled and experienced at reading and interpreting the results.

Dr. Sadiq earned his M.D. at JSS Medical College in Mysore, India. Transferring to the U.S., he attended the Mount Sinai School of Medicine, New York City, for an internship in internal medicine, followed by a residency in neurology at North Shore University, Manhasset, N.Y.

He completed fellowship training in clinical neurophysiology at the University of Texas Medical School in Houston.

Prior to joining Tanner Clinic in 2009, Dr. Sadiq practiced neurology at the Center of Neurological Services, Ogden, Utah, and Lakeview Neurology, Bountiful, Utah.

Dr. Sadiq is married and the father of two girls. He likes to golf and, sometimes, fish. But his greatest interest is growing super-sized vegetables. His long gourd, which grew to a length of more than 16 feet, set a Utah state record in 2014. His pumpkins, weighing in at 1,300 pounds or more, have also won awards.

What patients are saying about Dr. Sadiq

“I see Dr. Sadiq regularly for my MS. I know neurologists’ personalities are very different from most physicians. But as I continued treatments under his care, after six months to a year my impression completely changed. He is such a wonderful neurologist. He shows compassion towards his patients, not sympathy. His timeliness needs some improvement, but for someone that saved my life, who’s keeping track? No one.”   —, Aug. 29, 2014

Nerve Tests Provide Invaluable Information About the Body’s Health

Dr. Mohamed Sadiq is very good at conducting a very bad test. Not bad as in the test doesn’t work. Bad as in painful. As the neurologist says, “It is a very uncomfortable test.”

However, the electrodiagnostic tests he conducts — electromyography (EMG) and nerve conduction study (NCS), most often performed together — report valuable information about your nerves and muscles. In particular, the tests evaluate how electrical impulses travel through nerves to give instructions to the muscles.

The NCS can point to diseases affecting the nerves, such as a pinched nerve or carpal tunnel syndrome. The EMG, on the other hand, indicates whether your muscles are responding to the nerves. It can identify such neuromuscular diseases as muscular dystrophy or Lou Gehrig’s disease (amyotrophic lateral sclerosis), said Dr. Sadiq.

Symptoms that may indicate that the nerve is damaged include fatigue, weakness, tingling, numbness, pain, cramps and abnormal sensations, he said.

Electro-diagnostic procedures are almost always conducted by a neurologist. As a board-certified neurologist, Dr. Sadiq is trained in disorders of the brain, spinal cord and nervous system. By completing a fellowship in clinical neurophysiology, he’s acquired an additional specialized skill in providing and diagnosing such tests.

EMG (electromyography)

The needle EMG tests the health of muscles and the nerves that control them.

The test is conducted by inserting a needle into the muscle that’s showing signs of disorder — for instance, numbness or tingling. The needle records whether the electrical activity in the muscle is normal or diminished.

“A disease of the nerves will show changes in the muscle,” Dr. Sadiq explains. “So we stick a needle into the muscle and we look for certain changes.”

The EMG is performed using an instrument called an electromyograph. Dr. Sadiq can determine if the muscle is working properly by analyzing electrical activity that appears on a screen and through static-like noises played on a speaker.

NCS (nerve conduction study)

The nerve conduction test doesn’t involve needles; its discomfort comes from electrical shocks. If the EMG measures the nerve activity within the muscle, the NCS looks at the speed and strength of the nerve itself. The NCS, says Dr. Sadiq, “measures the function of the nerve, whether it’s right or wrong.”

The test is conducted using small shocks transmitted via electrodes placed on the skin over the area that’s having symptoms. Each shock is only about 200 milliwatts and lasts for a duration of .01 millisecond; however, adds Dr. Sadiq, some tests require more than 30 shocks.

Nerves can recover

In some cases, nerves that have died have the ability to regrow, Dr. Sadiq said. It depends on whether the disorder that damaged the nerve can be diagnosed — and then alleviated. “If it’s because of vitamin B12 deficiency,” he said, “we give vitamin B12 and the nerves fix themselves.”

However, diagnosing what damaged the nerve is not always possible. Consider neuropathy, for instance. Numbness in hands and feet has hundreds of causes, he said. Diabetes is the most common cause, but if you rule that out, a diagnosis becomes much more difficult.





Going for the Record

Sadiq-pumpkinYou’d never peg this doctor for a pumpkin grower. In the 2014 Utah Giant Pumpkin Growers weigh-off, Dr. Sadiq’s entry was the second largest pumpkin in the state, with the large squash weighing in at 1,386.5 pounds. The Standard Examiner newspaper wrote about his talent in “Growing giant pumpkins requires loving care, Ogden doc says.”
