Introduction to Electrodiagnostic Testing
Electrodiagnostic testing is a valuable diagnostic tool used by the experts at Desert Spine and Sports Physicians to assess nerve and muscle function. Unlike X-rays and MRIs, which provide images of bones and soft tissues, electrodiagnostic tests directly measure the electrical activity of nerves and muscles. This allows our specialists to detect and diagnose a wide range of neuromuscular disorders that may not be visible with other imaging techniques.
At Desert Spine and Sports Physicians, we utilize electrodiagnostic testing as part of our comprehensive approach to diagnosing and treating spine, sports, and musculoskeletal conditions. Our goal is to provide accurate diagnoses that lead to effective, personalized treatment plans.
Benefits of Electrodiagnostic Testing
Electrodiagnostic testing plays a vital role in pinpointing the location and severity of damage, differentiating between acute and chronic injury, and prognosticating outcomes of nerve and muscle conditions. The results then help guide treatment plans tailored to each patient’s needs.
It is crucial in identifying the root causes of various symptoms, including:
- Pain
- Numbness and Tingling in Hands
- Numbness and Tingling in Feet
- Weakness
Common conditions we evaluate with electrodiagnostic testing include:
- Lumbar radiculopathy
- Cervical radiculopathy
- Brachial/lumbar plexopathy
- Carpal tunnel syndrome
- Ulnar neuropathy/Cubital tunnel syndrome
- Peripheral nerve entrapment
- Peripheral Neuropathy
- Myopathy
At Desert Spine and Sports Physicians, electrodiagnostic testing involves two parts:
- Nerve Conduction Studies (NCS)
- Electromyography (EMG)
By combining these complementary tests, our Physical Medicine and Rehabilitation (PM&R) specialists gain a complete picture of your nerve and muscle function.
The Electrodiagnostic Testing Procedure
Nerve Conduction Studies (NCS): NCS helps diagnose nerve function by measuring the speed and strength of electrical signals traveling through nerves.
- How it works: A stimulator device delivers mild electrical pulses to the nerves which are recorded by electrodes stickers applied to the skin over the muscles controlled by those nerves; the electrodes record the muscles’ response to the electrical stimulation of the nerves.
- What to expect: Patients may experience mild and brief twinges or muscle twitches during the test.
Needle Electromyography (EMG): EMG assesses muscle health and function, helping to diagnose conditions affecting muscles and the nerves controlling them.
- How it works: A thin needle electrode which is about the size of an acupuncture needle is inserted superficially into various muscles to record their electrical activity.
- What to expect: Patients may feel a brief pinch as the needle is inserted, followed by mild discomfort that resolves quickly.
Comfort and Safety During the Test
At Desert Spine and Sports Physicians, we prioritize your comfort and safety during electrodiagnostic testing. While some patients may experience mild discomfort, most find the tests tolerable. Our experienced Arizona-based physicians use techniques to minimize any potential discomfort.
In addition, we use sterile, disposable needles to ensure the highest level of safety and minimize infection risk. Before the test, we’ll discuss any specific medical conditions or concerns you may have to ensure the procedure is safe for you.
Preparing for Your Electrodiagnostic Test
At Desert Spine and Sports Physicians, we want to ensure you understand what an electrodiagnostic test is and are fully prepared for the procedure. Here’s what you need to know:
Pre-Test Guidelines
- There are no restrictions on activity before or after the testing.
- Continue taking your regular medications, including any pain medicines.
- You will be awake and communicating with the physician throughout the entire test.
- We do not use anesthesia for this test, as it would interfere with obtaining accurate information from your muscles and nerves.
- Please inform your physician prior to the examination if you:
- Are taking blood thinners (such as Coumadin, Eliquis, Xarelto, and Plavix)
- Have hemophilia or other blood clotting disorders
- Have a cardiac pacemaker, implanted defibrillator, or other implanted electrical device
- Use a TENS unit (transcutaneous electrical nerve stimulator)
Day of the Test
- Wear loose, comfortable clothing that allows easy access to your arms and legs.
- Avoid applying skin lotions or oils on the day of the test, as these can interfere with the quality of the electrical signals.
- The test is performed while you’re awake, allowing you to communicate with the physician throughout the procedure.
- The test takes between 30 and 60 minutes.
- There are no lasting after-effects, so you can resume your normal activities immediately after the test.
Understanding Test Results
After your electrodiagnostic test at Desert Spine and Sports Physicians:
- Our specialists will carefully analyze and interpret the results.
- You can expect to receive a comprehensive report within a few days of the test.
- We’ll communicate the results to your referring physician and discuss them with you in detail.
- Based on the findings, we’ll work with you to develop a personalized treatment plan that aligns with our unique, whole-person approach to care.
