If you’ve experienced uncomfortable numbness and tingling, or weakness that makes everyday tasks feel impossible, your body is telling you something important. Getting to the root of those symptoms requires more than a physical exam. It requires looking directly at how your nerves and muscles communicate.
As a leading neurologist in New York City, Dr. Ashwin Malhotra with Neurodiagnostics Medical P.C. uses advanced EMG tests and nerve conduction studies to identify and quantify neurological problems with precision. That gives patients the clarity they need to pursue targeted treatment.
Early Diagnostic Testing Is Critical for Successful Treatment
The scale of nerve and muscle disease in the United States makes electrodiagnostic testing more essential than ever.
The NIH estimates that more than 20 million Americans have some form of peripheral neuropathy, and the actual number is almost certainly higher because many go untested. Diabetes, the leading cause of polyneuropathy in the U.S., now affects roughly 40 million Americans, according to the CDC.
Meanwhile, peripheral neuropathy prevalence rises to 8% or higher in older adults. These massive numbers underscore the critical importance of timely, accurate electrodiagnostic evaluation for millions of patients.
What Is an EMG Test, and Why Does It Matter?
An electromyography (EMG) test evaluates muscle electrical activity by recording electrical signals produced when a muscle is at rest and during contraction.
The physician inserts a thin needle electrode into selected muscles, and the resulting waveforms are displayed on a precision monitor. Healthy muscles generate predictable patterns, while abnormalities reveal tell-tale signs of disease.
EMG tests are valuable for diagnosing conditions affecting the neuromuscular system, including:
- Radiculopatía
- Motor neuron diseases such as ALS
- Myopathies
- Muscular dystrophies
When a muscle shows spontaneous activity at rest, which should not normally occur, this points to denervation, meaning a nerve connected to that muscle has been damaged. Additionally, small, irregular motor unit potentials suggest a primary muscle disorder. The readings that result from these distinctions can completely change a patient’s treatment plan.
What Is a Nerve Conduction Study, and What Can It Reveal?
A nerve conduction velocity (NCV) study is a diagnostic test measuring how fast and strongly electrical signals travel as part of your peripheral nerve function.
Surface electrodes are placed on the skin over specific nerves, a brief stimulus is delivered, and the response is recorded downstream. The neurologist measures several variables to compare values to established norms:
- Speed (conduction velocity)
- Strength (amplitude)
- Timing (latency)
Slower-than-normal signals indicate myelin sheath damage, while reduced amplitude suggests nerve fiber loss.
Nerve conduction studies are the non-invasive component of comprehensive electrodiagnostic testing and are usually performed first. The tests are sensitive to multiple conditions, including carpal tunnel syndrome and diabetic peripheral neuropathy.
How These Tests Work Together in a Neuropathy Evaluation
For patients experiencing neurological symptoms like numbness and tingling, comprehensive neuropathy evaluations using both EMG tests and nerve conduction studies provide a picture that imaging cannot.
An MRI can reveal structural problems like a herniated disc, but it cannot tell a neurologist whether the nerve root is actually injured or how severely. Electrodiagnostic testing fills that gap with objective, measurable data that directly informs treatment and helps avoid unnecessary procedures.
When neuromuscular disorders such as myasthenia gravis or Guillain-Barré syndrome are suspected, combining NCV and EMG testing is especially beneficial.
In myasthenia gravis, the NCV may appear normal while repetitive nerve stimulation on an EMG reveals a characteristic fading muscle response. Guillain-Barré syndrome attacks peripheral nerve myelin sheaths, resulting in dramatically slowed conduction velocities.
Accurate distinction between these conditions enables neurologists to prescribe appropriate treatment from the outset.
Finding a Top Neurologist in New York for Accurate Electrodiagnostic Testing
The quality of results depends heavily on the clinician’s expertise in performing and interpreting the test. That’s why choosing a top neurologist in New York matters enormously. Work with a physician who is board-certified and a member of the American Association of Neuromuscular & Electrodiagnostic Medicine.
An experienced doctor integrates electrodiagnostic findings with each patient’s symptoms, examination, imaging, and lab work to build a complete clinical picture rather than treating numbers in isolation.

Frequently Asked Questions About EMG Tests and Nerve Conduction Studies
Here are answers to some of the questions patients ask most often.
Can I Eat and Drink Normally Before My Appointment?
Yes, you may eat and drink as usual before your testing. However, avoid applying lotions, creams, or oils on the day of the appointment, as they can interfere with electrode contact and signal quality.
Can Children Undergo EMG and Nerve Conduction Testing Safely?
Yes, we can provide these diagnostic tests for pediatric patients when clinically indicated. The procedure is the same as for adults, though neurologists typically take extra care to explain each step and minimize discomfort for younger patients during the session.
How Long Does a Combined EMG and Nerve Conduction Study Appointment Typically Take?
Most sessions for combined EMG tests and nerve conduction studies last between 60 and 90 minutes, depending on how many nerves and muscles need to be tested. More complex cases involving multiple limbs or widespread symptoms may require additional time.
