Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Direct Stimulation Of Spinal Nerve Roots To Determine Sensory And Motor Innervation Patterns

Further study details as provided by Lahey Clinic:

Primary Outcome Measures:
  • Build a database of spinal nerve root innervation utilizing direct nerve root stimulation [ Time Frame: Data collected during surgery and a 30 day post-op visit ]

Secondary Outcome Measures:
  • Compare clinical symptoms of the patient to the direct muscle activation via spinal nerve root stimulation [ Time Frame: Data collected during surgery and a 30 day post-op visit ]

Estimated Enrollment: 1000
Study Start Date: May 2006
Estimated Study Completion Date: December 2016
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Detailed Description:
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.

Ages Eligible for Study:   18 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
All neurosurgical patients will be screened for potential eligibility from the Neurosurgery Department's Clinical and operative schedules.

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
