Prospective Evaluation of Mechanomyography Versus Triggered Electromyography for Intraoperative Assessment of Cortical Breaches During Instrumented Lumbar Spine Surgery

Francis Farhadi·interventional·Posted Apr 28, 2022·Updated Aug 19, 2025

In Brief

A clinical study evaluating Triggered Electromyography and Mechanomyography for Low Back Disorder. Completed, enrolled 65 participants across 1 site.

Detailed Summary

The purpose of this study is to determine how well mechanomyography (MMG) and electromyography (EMG) prevent cortical bone breaches, or the pinching of a nerve from screw placement, in patients having lower back surgery requiring hardware. Both MMG and EMG are devices approved by the FDA to detect the location of nerves during surgery so they can be avoided. The results from both tests will be compared to one another to determine if one is better at accurately locating nerves than the other.

Interventions

Triggered Electromyographydevice

Triggered electromyography will be used during surgery to detect nerve impingement by pedicle screws used for spinal fusion. Threshold stimulation data from the device will be recorded.

Mechanomyographydevice

SENTIO MMG ball tip probe will be used during surgery to detect nerve impingement by pedicle screws used for spinal fusion. Threshold stimulation data from the device will be recorded, and the accuracy compared to the data from the triggered electromyography.
