Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Intraoperative neurophysiological monitoring will be performed to assess motor evoked potentials (MEPs). A neurophysiologist will determine if there is a decrease in MEP amplitude of more than 50% compared to the baseline. | — |
Secondary
| Measure | Time frame |
|---|---|
| Changes from baseline in the following evaluation items Somatosensory Evoked Potential (SEP) Numerical Rating Scale (NRS) Physical examination findings (Manual Muscle Testing (MMT), dermatomes of pain and numbness, presence or absence of bladder and bowel dysfunction) Occurrence of adverse events | — |
