Electromyography (also called EMG) is a diagnostic test useful in diagnosing nerve diseases (e.g. neuropathies) and muscle diseases (e.g. myopathies). By the term “electromyography” in general we intend both  “nerve conduction speed” or “electroneurography” (ENG) and the true and proper electromyography (“needle” EMG).

For the diagnosis of which diseases is electromyography useful?

• Carpal tunnel syndrome (or median nerve trapping in the carpal tunnel – wrist)
• Ulnar sulcus syndrome (or ulnar nerve trapping in the elbow)
• Guyon’s syndrome (or ulnar nerve trapping in Guyon’s canal – wrist)
• Tarsal tunnel syndrome
• Radiculopathies
• Polyneuropathies (e.g. diabetic neuropathy)
• Plexus pathologies
• Amyotrophic lateral sclerosis
• Muscle diseases (e.g. myopathies and myositis)
• Diseases of the neuro-muscular junction (e.g. myasthenia gravis)
• and other diseases…
