Electromyography (EMG) is a diagnostic procedure that measures the electrical activity of muscles. It involves placing small electrodes on the skin or inserting fine needles into the muscle to detect electrical signals produced during muscle contraction. This information helps assess the health of muscles and the nerves controlling them. EMG is commonly used to diagnose conditions such as muscle disorders, nerve injuries, and neuromuscular diseases. By analyzing the electrical signals, healthcare professionals can identify abnormalities that may indicate underlying health issues, guiding appropriate treatment and management strategies.
