Diseases that affect the nerve-muscle connection, such as myasthenia gravis.

Muscle disorders, such as polymyositis or muscular dystrophy.To help diagnose or rule out several conditions, EMG results are often necessary if you have:

Numbness, tingling or paralysis in the limbs.Persistent pain in the feet, legs, arms or hands.Difficulty speaking, chewing or swallowing.If you have signs or symptoms that may indicate a nerve or muscle disorder, your doctor might order an EMG.

Before an EMG Test, What Should You Know? The findings of EMG will help the doctor identify muscle diseases, nerve damage, and disorders that influence the nerve-muscle relation. Tingling, numbness, or unexplained stiffness in the muscles may be part of these effects. When someone is displaying signs of a muscle or nerve dysfunction, a doctor may order an EMG. These electrical signals are converted into diagrams or numbers by an EMG, helping doctors provide medical advice. They relay electrical impulses that induce contraction and relaxation of muscles. Such nerve cells are referred to as motor neurons. Electromyography (EMG) is a medical test that involves nerve conduction study of the muscles and the nerve cells that regulate them in terms of wellness.
