Advanced Diagnostic Procedures for the Nervous & Muscular Systems

Diagnostic ProceduresMultispecialty healthcare centers in Brooklyn, NYC offer a wide range of nonsurgical pain management options for musculoskeletal injuries. They provide patients with appropriate treatment plans after making a proper diagnosis using cutting-edge diagnostic tools. Let’s look at the diagnostic methods used in leading health care centers:

MRI Scan

MRI (Magnetic Resonance Imaging) provides many advantages in terms of diagnosis. The MRI scanner makes use of magnets that are powerful enough to generate a really strong magnetic field and radiofrequency energy. With this, the scanner uses computers for producing images of the body’s soft tissues. MRIs generate much clearer views of the organs making up the body’s nervous system, such as the spinal cord, brain and nerves. They also provide a clearer view of the body’s non-bony parts such as the tendons, ligaments and muscles. MRI diagnostics help in a wide range of injuries including injuries of the joints such as the knee or shoulder, sports injuries and other conditions. A brain MRI produces detailed images of the brain and the brain stem.

Open MRI

Further development on the MRI scan is the open MRI which provides a much more comfortable and convenient scanning experience for patients. As the name suggests, open MRI is open from all sides, so the patient does not enter a tunnel. It thereby gets rid of the claustrophobic feeling. The patient can also be positioned in a manner that enables the image quality to come through well. In just about 30 minutes or less, the scanning can be completed.


An electronystagmogram (ENG), or the electronystagmography test, helps measure the normal movement of the eye as well as involuntary and quick eye movements while also analyzing the muscles controlling these eye movements. These movements are called nystagmus. With the video ENG, you can also analyze how the inner ears, the eyes and the brain perform the integral task of helping you maintain your body’s position and balance. It is the primary diagnostic procedure for identifying vertigo. What the electronystagmogram test does is identify whether the vertigo you are having is the result of problems with the inner ear, that usually cause balance issues and vertigo, or the result of a trauma or even disease or virus.

ENG basically consists of some sensory tests where electrodes are placed above your eyes and below them to measure how you react to motion, light and the perception of depth. The test also measures how your ear fluids behave in those ear canals. The factors causing vertigo are identified and isolated. ENG is recommended when you complain of balance loss, dizziness, tinnitus, nausea and vomiting.

Video ENG

In video ENG or VNG, a binocular camera is used instead of electrodes. The binocular camera is fitted to the patient and the camera captures movements of the eye on video. These movements are measured, just like how the electrodes measure them.

The NCV & EMG Tests

Another advanced diagnostic procedure is the NCV EMG test. “NCV” is the abbreviation of Nerve Conduction Velocity test. It is also called nerve conduction study (NCS) and is usually performed with the EMG or electromyography. While the EMG helps detect any disease affecting the nerves and muscles by recording electrical signals passing through the muscles, the NCV test assesses any nerve dysfunction or damage by measuring the speed at which electrical signals travel through the peripheral nerves.

The NCV EMG test is usually prescribed when you feel weakness, numbness or soreness in the muscles. The test is conducted to identify whether the problem lies in the muscle or the nerve. You could be experiencing numbness, tingling, cramping, pain or weakness in your legs, back, wrist or any other part of your body. The NCV and EMG tests can detect an injured nerve. Conditions that can be detected or ruled out are muscular dystrophy, carpal tunnel syndrome, herniated disk, Guillian-Barre syndrome, pinched nerves and other conditions. If you are recovering from a nerve injury, NCV can analyze its progress.

The Procedures

The NCV test is done with the help of electrode patches that are attached to the patient’s skin on the region where the nerve runs beneath. One electrode transmits an electrical impulse mildly to the respective nerve. The response of the nerve is recorded by the other electrodes. The speed at which the signal travels indicates the health of the nerve.

The EMG test involves an electrode as well as a thin needle penetrating the skin right down to your muscle. You will be asked to contract the concerned muscle. The test ultimately identifies whether your muscles have responded to nerve signals well.

Advanced diagnostic modalities and customized treatment are the hallmarks of advanced, multispecialty healthcare centers in Brooklyn, NY.
