SERVICES PROVIDED
What we monitor...
Somatosensory Evoked Potentials (SSEP)
Structures Monitored: The posterior sensory pathways of the spinal cord starting from the ends of the limbs, running up the spine and to the brain
Used for: Spine, cranial, peripheral nerve and vascular procedures
Transcranial Motor Evoked Potentials (TcMEP)
Structures Monitored: The anterior motor pathway of the spinal cord starting at the brain, running down the spinal cord and recorded from peripheral muscles of the arms and legs
Used for: Spine, cranial and vascular procedures
Spontaneous (free-run) Electromyography (EMG)
Structures Monitored: Muscle group that is innervated by nerve roots at risk during procedure
Used for: Spine, cranial, ENT, and vascular procedures
Triggered Electromyography (tEMG)
Structures Monitored: Muscle group that is innervated by nerve roots at risk during procedure
Used for: Spine, ENT, and cranial procedures
Electroencephalography (EEG)
Structures Monitored: Brain Activity
Used for: Spine, cranial, and vascular procedures
Visual Evoked Potential (VEP)
Structures Monitored: Optic nerve pathway
Used for: Cranial procedures
Brainstem Auditory Evoked Response (BAER)
Structures Monitored: The auditory pathway
Used for: Cranial and ENT procedures
Cortical Mapping and Language Mapping
Structures Monitored: Identification of specific areas of the brain (language, motor cortex, sensory cortex) by stimulating localized areas of the brain
Used for: Cranial procedures
Phase Reversal
Structures Monitored: Motor and sensory cortex of the brain and the central gyrus
Used for: Cranial procedures
