Electromyography

Electromyography is a technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed using an instrument called an electromyograph to produce a record called an electromyogram.

Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the afferent neuron that control them (motor neurons). EMG outcomes can expose nerve dysfunction, muscle dysfunction or issues with nerve-to-muscle signal transmission.

Motor neurons send electrical signals that cause muscles to contract. An EMG utilizes tiny devices called electrodes to translate these signals into graphs, sounds or numerical values that are then interpreted by an expert.

During a needle EMG, a needle electrode placed directly into a muscle records the electrical activity because muscle.

A nerve conduction study, another part of an EMG, utilizes electrode sticker labels used to the skin (surface area electrodes) to measure the speed and strength of signals taking a trip between two or more points.

Electromyography

Your doctor may order an EMG if you have signs or symptoms that may indicate a nerve or muscle disorder. Such symptoms may include:

  • Tingling
  • Numbness
  • Muscle weakness
  • Muscle pain or cramping
  • Certain types of limb pain

When you’re in pain, your quality of life decreases dramatically – and every aspect of your everyday life is impacted. Just because you have a condition that causes pain, it doesn’t mean you have to live with the pain day in and day out. The pain management specialists at the Minnesota Pain Institute in Hopkins, MN can help you get relief.

EMG results are often necessary to help diagnose or rule out a number of conditions such as:

• Muscle disorders, such as muscular dystrophy or polymyositis
• Diseases affecting the connection between the nerve and the muscle, such as myasthenia gravis
• Disorders of nerves outside the spinal cord (peripheral nerves), such as carpal tunnel syndrome or peripheral neuropathies
• Disorders that affect the motor neurons in the brain or spinal cord, such as amyotrophic lateral sclerosis or polio
• Disorders that affect the nerve root, such as a herniated disk in the spine
