Most of us take for granted our ability to move, feel, and control our muscles until something goes wrong.

When muscle weakness, numbness, or unexplained pain disrupts daily life, the root cause often lies deep within the intricate network of nerves and muscles. But how do we detect an issue that can’t be seen on an X-ray or MRI?
Electromyography (EMG) is the answer. This advanced diagnostic tool allows specialists to assess the electrical activity of muscles and the nerves that control them, offering a precise and comprehensive evaluation of neuromuscular health. For patients recovering from trauma, sports injuries, or neurological disorders, EMG provides critical insights that guide effective treatment and rehabilitation.
In this blog, we will explore the importance of EMG testing, what it diagnoses, how it is performed, and what patients can expect before, during, and after the procedure. Whether you are experiencing persistent pain, weakness, or nerve-related symptoms, understanding EMG is the first step toward identifying the cause and finding the right path to recovery.
Electromyography (EMG) is a diagnostic test that evaluates the health of muscles and the nerve cells (motor neurons) that control them. Motor neurons send electrical signals to the muscles, allowing them to contract. EMG measures these signals, helping physicians diagnose neuromuscular disorders.
Often, EMG testing includes Nerve Conduction Studies (NCS), which measure how well electrical impulses travel through nerves. Together, these tests help determine if a patient’s symptoms stem from a nerve disorder, muscle disorder, or an issue at the connection between the two.
For example, if a patient is experiencing muscle weakness, EMG can help determine whether the weakness originates from nerve dysfunction, such as a pinched nerve in the spine, or a muscle disorder like muscular dystrophy. If a patient suffers from numbness or tingling in the hands, EMG and NCS can assess whether the problem is due to carpal tunnel syndrome, a nerve compression in the wrist, or another underlying condition. In cases of chronic back or neck pain after trauma, EMG can reveal whether the pain is linked to nerve irritation, spinal nerve compression, or another neurological issue.
EMG is particularly beneficial for patients with traumatic injuries, as it helps detect nerve damage that may not appear in imaging tests. The test is commonly used to diagnose:
If you have experienced trauma, fractures, or surgery and now have weakness, numbness, tingling, or chronic pain, an EMG can help pinpoint the cause and guide your treatment.
EMG is recommended for patients experiencing:
These symptoms often arise after trauma, sports injuries, or surgery, making EMG a critical test for diagnosing nerve and muscle damage.
To ensure accurate results, proper preparation is essential. Following these guidelines can make the test easier and help obtain the most precise readings:
By following these simple steps, you help ensure the most accurate and useful results from your EMG test.
Our specialists will guide you through each step to ensure you feel comfortable and informed throughout the procedure. EMG testing consists of two parts:
While some mild discomfort may occur, the procedure is generally well tolerated. Our team will ensure you feel at ease throughout the test, addressing any concerns you may have along the way.
Once the test is completed, patients can return to their normal activities immediately. Some may experience mild muscle soreness, but this should resolve within a day or two. The physician will review the results and discuss the next steps for treatment.
Patients often ask if EMG is painful or risky. While the test may cause mild discomfort, it is a safe and effective diagnostic tool with minimal risks. The nerve conduction study may cause a brief tingling sensation, while the needle EMG may result in temporary muscle soreness. EMG does not involve radiation, and patients can resume normal activities immediately after the test.
Most patients experience only mild discomfort. The nerve conduction study feels like a brief tingling sensation, while the needle EMG may cause temporary muscle soreness similar to that of a small injection.
Your doctor may discuss preliminary results immediately, but a full report is typically available within a few days. The findings will be used to determine the best treatment plan for your condition.
Yes, you can drive and resume normal activities after the test. If you experience any soreness, it is usually mild and temporary.
Depending on the results, your doctor may order additional imaging tests such as an MRI or CT scan or recommend specific treatments to address your condition.
At University Orthopedic Care (UOC), we prioritize excellence in diagnosing and treating nerve and muscle disorders.
Our specialists use the latest EMG and NCS technology for precise and reliable results. We have a team of highly trained, board-certified experts in neuromuscular diagnostics and rehabilitation.
We specialize in trauma-related nerve injuries, offering integrated orthopedic and neurological expertise. Above all, we take a patient-centered approach, ensuring that every patient feels informed, comfortable, and supported throughout their care.
Your nervous system controls every movement, sensation, and reflex in your body, and when something feels wrong, getting a precise diagnosis is essential. Electromyography is a safe, highly effective diagnostic tool that helps identify nerve and muscle disorders that might not appear on standard imaging tests. With early detection, patients can begin targeted treatments that improve mobility, reduce pain, and enhance their overall quality of life.

Yes, each of our locations takes pride in being registered with the Agency for Health Care Administration (AHCA) and achieving accreditation by The Joint Commission. With these two associations, we ensure our patients receive the highest-quality care coupled with detailed attention to patient safety throughout the process.
Surgery is usually arranged 3 to 4 weeks after your visit with the surgen. This time interval allows to complete any required medical clearances and lab work. That said, we understand the impact of severe pain and can often expedite the surgery date if required.
Although every patient in situation is unique, often times a minimally invasive surgical approach may be available. At University Orthopedic Care, our surgeons utilize the most advanced approaches for numerous benefits:
Choosing the right orthopedic specialist is essential for optimal recovery, and experience plays a critical role in achieving the best outcomes.
Look for a specialist with board certification and advanced fellowship training in relevant areas like joint replacement or complex fracture care.
At University Orthopedic Care, our board-certified experts bring years of experience and utilize cutting-edge technology to treat a variety of conditions. We specialize in managing traumatic injuries and offer a comprehensive range of treatments, including minimally invasive procedures and regenerative medicine.
