Best Doctor List Near You for Electromyography(emg) in Newfoundland and labrador

Electromyography (EMG) is a diagnostic procedure used to assess the health of muscles and the nerve cells that control them, known as motor neurons. During an EMG, small needles, called electrodes, are inserted into the muscles to measure electrical activity during muscle contraction and rest. The electrical signals are then displayed on a monitor, providing detailed information about nerve and muscle function. EMG is commonly used to diagnose conditions that affect the muscles or nerves, such as carpal tunnel syndrome, peripheral neuropathy, muscular dystrophy, amyotrophic lateral sclerosis (ALS), and other neuromuscular disorders. By evaluating the electrical activity in muscles, EMG helps determine whether muscle weakness or paralysis is due to a muscle condition or a nerve disorder. The primary cause for conducting an EMG is to investigate symptoms such as muscle weakness, tingling, numbness, or unexplained muscle pain, which may indicate underlying nerve or muscle problems. Although EMG is generally safe, it can have some complications. The most common side effects are mild discomfort or pain at the needle insertion sites, which can cause bruising or temporary muscle soreness. In rare cases, there may be bleeding or infection at the electrode insertion points, especially in patients with bleeding disorders or those on blood-thinning medications. Additionally, if the needle accidentally punctures a lung or other structures, it can lead to more serious complications like a pneumothorax. Proper technique and careful monitoring during the procedure help minimize these risks, making EMG a valuable tool for diagnosing neuromuscular conditions.
