Cervical spondylotic myelopathy is the most common
degenerative disease after the age of 55. The cervical
spinal cord becomes impinged, causing motor and sensory
dysfunction and gait abnormalities. When there is damage
to the brain or spinal cord, cortical plasticity has
been shown to occur as a compensatory technique to
maintain function. Ipsilateral motor areas have been
shown to be recruited when cortical demand exceeds
cortical output. The purpose of this study was to
characterize and quantify the activation patterns of the
ipsilateral motor areas and its role in functional
recovery.
