Abstract
Cervical Spinal Stimulation at Different Levels Evoked Multisegmental Motor Responses in the Lower Limbs
Highlights
The multisegmental motor responses (MMR) from upper limbs has been recently reported using cervical and thoracic vertebral stimulation [1,2]
Large signal amplitudes were obtained in all tested muscles with the largest amplitude in the vastus medialis oblique (VMO) and SOL followed by the Medial Hamstrings (MH) and Tibialis Anterior (TA)
These Multisegmental Motor Responses (MMR) records could be used for non-invasive testing of ascending and descending spinal pathways integrity between the cervical and lumbosacral spinal segments [3]
Summary
The multisegmental motor responses (MMR) from upper limbs has been recently reported using cervical and thoracic vertebral stimulation [1,2]. These MMR records could be used for non-invasive testing of ascending and descending spinal pathways integrity between the cervical and lumbosacral spinal segments [3]. Upper and lower limb MMRs have been recorded using stimulation at the T11–12 vertebral segments and have suggested strong ascending and descending propriospinal pathway functioning, originating from the lumbar spinal segment [2,4]. Cervical spinal stimulation has been reported to generate MMR in the upper limbs only, with minimal responses in the lower limbs [2].
