Direct Stimulation Of Spinal Nerve Roots To Determine Sensory And Motor Innervation Patterns

In this large scale study it is proposed to examine root-to-muscle innervation directly,
using the standard Intra-Operative Monitoring procedures during scheduled cervical and
lumbar spinal surgeries. The study would directly map muscle and sensory distributions of
nerve root innervations with no additional risk to patients.

Inclusion Criteria:

- Patients undergoing either cervical or lumbar cord procedures at Lahey Clinic and
during which the surgeon has requested intra-operative neurophysiologic monitoring.

- Surgery performed by a neurosurgeon

- Participant must be ≥ 18 years of age or ≤ 85 years of age

- Participant, or legally authorized representative, has been informed of the nature of
the study and has provided written informed consent, approved by the Lahey Clinic IRB

Exclusion Criteria:

Past medical history significant for any of the following:

- Peripheral Neuropathy

- Patients with Diabetes Mellitus

- Neuromuscular disease that would interfere with intra-operative recordings

- The Investigator determines that the patient should not be included in the study for
reason(s) not already specified
