EMG Finding According to the Type of Lumbar Disc Herniation

A Study for Electrodiagnostic Finding According to the Type of Lumbar Disc Herniation on MRI

Disc herniation is a common cause of low back pain and leg pain. Electromyography is the only test that can objectively examine nerve damage caused by a lumbar disc herniation. This study aimed to compare the MRI findings of disc herniation and the aspects of electromyography.

Inclusion Criteria:

• Radicular pain within 6 months
• Disc herniation confirmed by lumbar MRI
• undergoing electromyography

Exclusion Criteria:

• Patients who refused electromyography
• Patients taking warfarin
• Lower limb amputation patient
• Pregnant women
• Patients who have undergone surgical treatment for disc herniation
• Patients with peripheral neuropathy ( AIDP, CIDP, diabetic amyotrophy, peroneal pals et al.)
