What Makes It Special:

Unlike other kinds of pain and discomfort you may experience, pain caused by your nerves can come from the most unexpected places. Nerve testing finds the true source of your numbness, tingling, and pain.

Nerve Testing

Are you tired of numbness and discomfort throughout your body, and having no definite understanding of its underlying cause?

Pinched, inflamed, and damaged nerves can cause havoc throughout the body, leading to issues such as tingling and numbness in a completely different part of the body. This makes nerve-related issues difficult to diagnose, as pain in the leg may have nothing to do with the leg at all. With electromyography nerve testing, we can determine the exact source and cause of your tingling, numbness, and pain, and begin your pain relief from there.

If you are experiencing tingling, numbness or muscle pain, an electromyography (EMG) and nerve conduction study (NCV) carried out by an expert physiatrist can help you identify the root of uncomfortable, debilitating and sometimes scary symptoms. At Montville Medspa & Pain Center, Dr. Donna D’Alessio, a physiatrist who specializes in central and peripheral nervous system functioning, practices a whole-body approach to medicine, customizing each treatment to meet her patients’ specific needs. She is board certified in Physical Medicine and Rehabilitation.

Chronic pain is often caused by an underlying condition, such as arthritis, diabetes, peripheral nerve disease or spinal issues such as a compressed nerve from disc herniations, degenerative changes or traumatic injury. In certain cases, the cause of chronic pain is mysterious, which is why it is critical to choose a physician such as Dr. D’Alessio who carries out today’s most advanced tests (such as EMGs and NCVs) and treatments in pain management.

Symptoms an EMG/NCV helps to diagnose include:

  • Chronic pain
  • Weakness
  • Numbness
  • Tingling

Physiatrist, Donna D’Alessio, MD

For close to a decade, Dr. D’Alessio has carried out electromyography (EMG) and nerve conduction studies (NCV) to determine the source of tingling, numbness,  pain and weakness. This diagnostic procedure assesses the health of muscles and the nerve cells that control them (motor neurons). Properly performed, an EMG/NCV performed by Dr. D’Alessio can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.

D’Alessio completed her medical degree at St. George’s University in the West Indies and an internship in Internal Medicine at SUNY Downstate Medical Center at Long Island College Hospital in Brooklyn, New York. She then went on to complete a residency in Physical Medicine & Rehabilitation at Mount Sinai Hospital in New York City.  In her final year of residency training, she was appointed to and served as chief resident. Today she is highly regarded for carrying out EMG/NCVs and is frequently sought out by referring physicians and personal injury attorneys.


Nerve Testing FAQ

What is Electromyography (EMG) and Nerve Conduction Study (NCV)?

An Electromyography (EMG) and Nerve Conduction Study (NCV) is a type of diagnostic nerve test used to pinpoint injury. It is a way to see if muscles and nerves are responding properly to stimulation. Dr. D’Alessio uses EMG/NCV as a tool to help determine what is causing pain, numbness, tingling and/or weakness. EMG/NCVs are useful for diagnostic purposes and can help determine what can be done to treat conditions with interventional pain procedures including cortisone injections, nerve blocks or epidural injections.

How an EMG/NCV work?

EMG/NCV is a test where nerve pathways and electrical signals in the body are tested. Electric signals from your brain travel through neurons to move muscles; these signals can be detected just like the electricity in a house. For instance, this test is similar to how an electrician tests the signal between a light switch and fuse. The issue could be in the wiring — something impedes the signal — or the problem could be from the signal creator itself.

How is an EMG performed?

With care and expertise, Dr. D’Alessio stimulates nerve pathways and inserts thin needles into the muscle to read electrical currents in the body. The strength and speed of the signals transmitted across muscles and nerves are measured.

What conditions does an Electromyography help to diagnose?

An electromyography helps Dr. D’Alessio determine if you suffer from a range of conditions, including:

Pinched nerve

Peripheral neuropathy

Arthritis or other bone condition rubbing against a nerve

Herniated disc

Inflammation of nerves (such as carpal tunnel syndrome)

Degenerative muscular diseases

Degenerative neurological diseases

Are there Risks Associated with EMG/NCV testing?

EMG/NCV are relatively low-risk procedures. However, there could be interference if you have a pacemaker. In addition, a risk for bruising/bleeding and very low risk for infection exists post-procedure.

Dr. D' Alessio and her staff are top notch in every way, a rarity in medical offices. Dr. D'Alessio is truly amazing and I am more than thrilled with my experience in the office and the work she did to balance imperfections on my face. I was a long time patient and close friend of NJ's top dermatologist until he died 5 years ago, I never thought I'd find anyone as talented again. I will be using as many services as I can in this office!

Got the sculpsure procedure done today and the service was amazing! I felt very relaxed and Dr. D’ Alessio was very informative about what I should expect during the process. Anyone looking to get any of the services done here I will definitely recommend. I drove all the way from Brooklyn, NY that’s how much I recommend it!!!
