The team at Pain, Spine & Rehab Associates uses EMG and NCS testing to identify the cause of symptoms such as: An NCS shows if there is a blockage or damage in the nerve that prevents signals from reaching your muscles or your brain. The test stimulates specific nerves and monitors how the impulse travels to your muscles. What is an NCS?Ī nerve conduction study (NCS) is a test that measures how well signals travel through your nerves to your muscles. The team at Pain, Spine & Rehab Associates uses EMGs to monitor the nerve signals in your muscles and identify any irregularities that could be causing your pain. Your motor neurons transmit signals to your muscles, telling them to contract and relax. We serve patients from Orlando FL, Conway FL, Edgewood FL, Jensen Beach FL, Ocean Breeze FL, Rio FL, Palm Bay FL, Malabar FL, Melbourne FL, Atlantis FL, Palm Springs FL, Boynton Beach FL, Fort Pierce FL, White City FL, St Lucie FL, Plantation FL, Pine Island Ridge FL, Lauderhill FL, Winter Park FL, Bertha FL, Alafaya FL and surrounding areas.Electromyography (EMG) evaluates the health of your muscles and the nerves that control them. NCV and EMG tests are available at Global Neuro & Spine Institute. It may also be used to detect muscle disorders, conditions affecting the motor neurons in the spinal cord or brain, and conditions affecting the connection between the muscles and nerves. Disorders detected with an EMG include issues affecting the peripheral nerves such as carpal tunnel syndrome and issues with the nerve roots that exit your spinal column such as sciatica or pinched nerves. EMG tests can also be used by providers to rule out conditions. It can be used to determine whether these injuries and diseases exist, where they are located, and how severe they are.

Several injuries and diseases that affect your motor nerves and muscles can be diagnosed using an EMG. The electrical pulse will be recorded for how long it takes the muscle to respond. Other electrodes are placed over the muscles controlled by the nerve. Electrodes are used to stimulate a nerve with an electrical pulse. NCVs are performed by attaching two types of electrodes to your skin.

It is possible for your doctor to move the electrode to a different muscle or to a different part of the muscle.

While the electrical activity is being recorded, your doctor will ask you to tighten the same muscle slowly and steadily. When the needle electrode is inserted into a muscle, you may experience a quick, sharp pain. The electrical activity of the muscle will be recorded while it is at rest. A needle electrode will be inserted into a muscle during an EMG. The number of nerves and muscles your doctor tests will determine how long it will take. A nerve conduction velocity test can take between 15 minutes and an hour.

The duration of an EMG may range from 30 to 60 minutes.
