Normalization of sensorimotor integration by repetitive transcranial magnetic stimulation in cervical XXXX .

@entity3519 @entity1
Previous studies indicated that sensorimotor integration and plasticity of the sensorimotor system are impaired in @entity3519 @entity1 . We investigated motor evoked potential amplitudes and short latency afferent inhibition to examine corticospinal excitability and cortical sensorimotor integration, before and after inhibitory 1  Hz repetitive transcranial magnetic stimulation over primary sensory and primary motor cortex in @entity1 with cervical @entity3519 (n  =  12). Motor evoked potentials were recorded from the right first dorsal interosseous muscle after application of unconditioned transcranial magnetic test stimuli and after previous conditioning electrical stimulation of the right index finger at short interstimulus intervals of 25, 30 and 40  ms. Results were compared to a group of healthy age-matched controls. At baseline, motor evoked potential amplitudes did not differ between groups. Short latency afferent inhibition was reduced in cervical @entity3519 @entity1 compared to healthy controls. Inhibitory 1  Hz sensory cortex repetitive transcranial magnetic stimulation but not motor cortex repetitive transcranial magnetic stimulation increased motor evoked potential amplitudes in cervical @entity3519 @entity1 . Additionally, both 1  Hz repetitive transcranial magnetic stimulation over primary sensory and primary motor cortex normalized short latency afferent inhibition in these @entity1 . In healthy subjects, sensory repetitive transcranial magnetic stimulation had no influence on motor evoked potential amplitudes and short latency afferent inhibition. Plasticity of sensorimotor circuits is altered in cervical @entity3519 @entity1 .
