What Are EMG and Nerve Conduction Studies?
Electromyography (EMG) and nerve conduction studies (NCS) are specialized tests that assess the health of muscles and peripheral nerves.
Nerve conduction studies measure how well electrical signals travel through nerves.
EMG evaluates muscle activity and detects abnormalities caused by nerve or muscle disorders.
Together, these tests help identify the source of neurological symptoms.

These studies are commonly used to evaluate:
• Peripheral neuropathy
• Carpal tunnel syndrome
• Ulnar neuropathy
• Radiculopathy (pinched nerve)
• Sciatica
• Muscle disorders
• Weakness of unclear cause
Accurate diagnosis guides appropriate treatment planning.
