Treat your pain and live a better life…

best-pain-doctor-nycWelcome to my blog about pain. Unfortunately, many people suffer from chronic pain. As a board certified physician in physical medicine and rehabilitation, my specialty is treating these people with both acute and chronic pain.

A majority of my practice is working with patients that are experiencing back and neck pain.

My goal with this blog is to help patients who are experiencing any type of back or neck pain to understand what is causing their pain and discuss options that are available to end their pain. I hope to be able to provide readers with a portal that they can can use to educate themselves and facilitate treatment.

My specialty is my Interventional Spine Skills including cervical and lumbar epidural steroid injections, facet injections, medial branch blocks, Radiofrequency ablation, sympathetic ganglion blocks, spinal cord stimulator trials, sacroiliac joint injection, piriformis muscle block and musculoskeletal joint injection. I also perform many other procedures to alleviate acute and chronic pain.

I hope you enjoy reading my blog as much as I enjoy writing it and observing people from all over the world reading it.

Electromyography (EMG)

electromyography-EMG-best-doctor-nyc-01An electromyogram is a procedure that allows a doctor to analyze the effectiveness of a nerve. This is done through measuring the electrical stimulation sent to the muscle through the nerve. There are many reasons why a nerve may not be sending an effective electrical signal. This can be due to physical blockage, nerve damage, injury, or illness. Regardless of the reason for Limited nerve signal reception, an electromyogram will allow a doctor to objectively see how their patient is doing.

What is Electromyography?

Electromyography, as mentioned above, is a diagnostic test to determine how well both nerve and muscle systems are working. The way this is measured is through electrical signal. When the brain sends a signal to the body in order to act, it does so by stimulating neurotransmitters to release electrical signals. These electrical signals travel down the nervous system towards the muscle. When properly received through the nervous tissue, these signals are then transmitted two muscles. These muscles electromyography-EMG-information-procedure-specialist-nyc-02interpret the signal and use the electrical stimulation to activate movement. However, when there is clearly a lack of movement or weakness, an electromyogram can be done to determine the source. Alternatively, an electromyogram may be used to determine problems associated with sensory nerves. With sensory nerves, things are a little bit different. In this case, the electrical simulation is based on neurotransmitters provided from the sensory organs. This electricity then travels back up through the spinal cord toward the brain in order to relay important information. When this information isn’t received properly, an electromyogram may be recommended. Additionally, if sensations of numbness or tingling are reported, I may be able to determine the source of the problem.

How is Electromyography Used?

In order for electromyography to be used, the above criteria must be met. When one of these problems is being investigated, eye doctor will make use of electromyography. To do so, I need a needle electrode may be placed into a muscle so as to effectively read the electrical signal that is received by the muscle. Alternatively, electrode stickers can be placed across the skin to measure the speed and strength of electrical signals sent. This will allow doctors to get a glimpse of the nervous system and the ability to transmit the necessary electrical signal. Once these readings have been taken, a doctor can make a decision regarding treatment interventions required.

When Should Electromyography be Used?

EMG-test-for-extreme-cramping-other-symptoms-best-doctor-nyc-03There are certain conditions that may dictate the need for electromyography. This includes numbness, tingling, muscle weakness, or cramping. In addition, an electromyogram may be used to diagnose conditions such as carpal tunnel. Amyotrophic lateral sclerosis and polio can also be diagnosed with the help of an electromyography. Muscular dystrophy, myasthenia gravis, and even herniated discs can all be diagnosed with the help of an electromyogram. If you have a family history of any of the above-mentioned diseases, or feel you may have these conditions, an electromyogram can help get a definite answer.

Dr. Grimm answers the question: What is an EMG test?

What Is an EMG?

Best-EMG-Testing-Doctor-NYC-1Electromyography or EMG is a study of the electrical activity of muscles. If you have numbness or weakness your doctor may request an EMG to determine the cause. In cases of neck or low back pain associated with numbness or weakness of an arm or leg, an EMG can help to identify which nerve root is compressed or irritated. This can help guide treatment decisions.

An EMG test is routinely accompanied by a nerve conduction study in order to definitively identify the level of nerve involvement. In other words, your doctor wants to make sure that your leg numbness or weakness is not caused by a problem of your peripheral nerves.

Procedure: How is an EMG done?

Under sterile conditions, a very fine electrode is inserted into select muscle groups to measure their electrical activity at rest and during contraction. The electrical activity is visualized on a computer monitor and analyzed by the performing physician.

During the nerve conduction portion of the exam, select peripheral nerves are stimulated electrically and responses of the appropriate muscle groups are recorded. This test determines the integrity and function of your peripheral nerves.

Indications for an EMG

Best-EMG-Testing-Doctor-NYC-3An EMG and nerve conduction study is frequently performed in cases of neck or low back pain specifically for the purpose of identifying cervical or lumbar nerve root irritation. Assuming that nerve root irritation has been present for at least three weeks, the test can aid in localizing the level and severity of nerve root involvement. An EMG is a valuable adjunctive test in the evaluation of neck or low back pain when nerve root irritation is suspected.
