Conditions

Electromyography, Intervertebral Disc Displacement

Brief summary

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.

Interventions

DIAGNOSTIC_TESTelectromyography

Electromyography (EMG) is an electrodiagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles.
