Electromyography (EMG)

Electromyography (EMG) is a diagnostic procedure which is used to assess the health of muscles and the nerve cells that control them. EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.

Symptoms that may indicate a nerve or muscle disorder, include:

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

Our experts use EMG to diagnose or rule out a number of conditions, including:

• Muscular dystrophy or polymyositis
• Myasthenia gravis
• Carpal tunnel syndrome or peripheral neuropathies
• Amyotrophic lateral sclerosis or polio
