EMGs measure and evaluate the health and functionality of your muscles and nerves. This noninvasive test is performed in two parts – a nerve conduction study and a needle EMG.
During the nerve conduction study, your doctor will attach a series of electrodes to the symptomatic part of your body. These electrodes detect the electrical activity in your muscles to gauge how they communicate with your nerves. For the needle EMG, needle electrodes are inserted into the symptomatic muscles to measure their electrical activity when contracted as well as at rest.
An EMG typically takes 45 to 60 minutes to complete and is performed in the comfort of our office. You’ll spend the duration of the test reclined on a treatment bed or in a comfortable chair.
An EMG enables your doctor to analyze your nerve function and the line of communication between your nerves and muscles. This is a helpful tool in diagnosing many conditions, such as:
It is critical to receive a timely, accurate diagnosis to best treat the underlying causes of nerve problems. If you experience any of the following symptoms, your doctor may order an EMG:
Your neurologist will give you detailed, personalized instructions concerning your medications, so be sure to discuss all of the medications, vitamins and supplements you currently take. Be sure to inform your doctor if you have a pacemaker or implantable defibrillator.
It’s recommended to abstain from smoking in the hours prior to the test. It is also important to shower before the EMG and refrain from applying any creams or lotions. Be sure to wear comfortable clothing.
An electromyography test (EMG) is a diagnostic procedure used to evaluate the health of your muscles and the nerves that control them. This nerve testing, also known as EMG testing, helps detect nerve and muscle disorders by measuring electrical activity. Your neurologist at Brain & Spine Specialists will typically recommend EMG testing to identify the cause of symptoms like muscle weakness, numbness, or pain.
Most people find an EMG test mildly uncomfortable rather than truly painful. You might feel small pinches or brief electrical sensations when the needle electrode or EMG sensor is inserted, but these sensations typically last only a moment. At Brain & Spine Specialists, we make every effort to keep you comfortable throughout the electromyography procedure, and our neurologists will walk you through what to expect beforehand.
An EMG test helps diagnose various conditions affecting muscles and nerves, such as carpal tunnel syndrome, peripheral neuropathy, sciatica, muscle diseases, and nerve compression injuries. Neurologists use electromyographic studies to determine the exact location, severity, and cause of nerve or muscle dysfunction. Your care team at Brain & Spine Specialists will thoroughly explain your EMG test results and next steps for treatment.
During an EMG test, you’ll first relax comfortably while a specialist applies small EMG sensors to your skin. Then, tiny needle electrodes are gently inserted into specific muscles to record electrical activity. You may be asked to contract or relax your muscles during the procedure. The neurologist performing your test at Brain & Spine Specialists will clearly explain each step as it occurs.
An EMG test typically takes between 30 and 60 minutes, depending on the area being evaluated and the extent of testing required. If multiple areas need examination, it could take slightly longer. At Brain & Spine Specialists, we ensure the procedure is efficient and clearly communicated, helping you feel relaxed and informed throughout your visit.
During electromyography testing, your neurologist or technician will first place surface EMG sensors on your skin to evaluate nerve signals. Next, a fine needle electrode is gently inserted into selected muscles to measure electrical activity at rest and during contraction. You’ll likely be asked to tense and relax certain muscles so accurate readings can be recorded. The entire electromyography procedure at Brain & Spine Specialists is carefully guided and explained at every step.
Before your EMG test, avoid applying lotions, creams, or oils to your skin, as they can interfere with EMG sensors. It’s best to avoid caffeine and smoking for a few hours before the test, since they can affect muscle activity. At Brain & Spine Specialists, our care team will provide clear, detailed instructions to help you prepare and ensure accurate test results.
Several factors can interfere with EMG testing, including skin lotions, oils, or creams, excessive sweating, recent caffeine consumption, and certain medications that affect muscle activity. Anxiety or significant muscle tension can also affect results. The neurologists at Brain & Spine Specialists will guide you through proper preparation to ensure the best possible outcomes from your electromyography test.
When preparing for an EMG test, there are a few important guidelines: arrive with clean, lotion-free skin, wear comfortable clothing, and inform your doctor if you’re taking blood thinners or medications affecting muscle function. Relaxing your muscles during the test helps ensure accurate results. Your Brain & Spine care team will thoroughly review these rules with you prior to your electromyography procedure.
Before an EMG, it’s helpful to know that the test involves minimal discomfort and is designed to be safe and informative. Wear loose, comfortable clothing and avoid using skin lotions or oils on the day of your appointment. Inform your neurologist at Brain & Spine Specialists about medications you’re taking, as some can affect EMG results. Your doctor will thoroughly explain the procedure, preparation steps, and answer any questions to ease your mind.
identify potential issues. To ensure accurate results, relax your muscles, follow preparation instructions like avoiding caffeine and lotions, and communicate openly with your neurologist about medications. Your care team at Brain & Spine Specialists will ensure you understand every aspect of the procedure and results.
An EMG test focused on the foot typically takes between 30 to 45 minutes. The exact time can vary based on how many areas need evaluation. Your neurologist at Brain & Spine Specialists will let you know exactly what to expect for your specific electromyography test, ensuring you’re comfortable and prepared.
Factors like skin creams, lotions, sweat, caffeine, nicotine, muscle tension, and certain medications can interfere with EMG testing results. Your neurologist will guide you on what to avoid and how to prepare effectively. At Brain & Spine Specialists, careful instructions will be provided beforehand to ensure accurate, reliable electromyography test outcomes.
