Spinal N13 versus cortical N20 and dermatomal somatosensory evoked potential studies in patients with cervical radiculopathy
Spinal SEP; N13; Cervical Radiculopathy Abstract Introduction: Most studies on somatosensory evoked potentials (SEPs) in cases of cervical radiculopathy routinely analyze scalp (cortical) responses (mixed or dermatomal SEPs), depending mainly on evaluation of N20 whose origin is the primary somatosensory cortex. It was suggested that selective study of the N13 potential, might be a useful techn...
متن کاملSomatosensory conduction times and peripheral, cervical and cortical evoked potentials in patients with cervical spondylosis.
Peripheral, cervical and cortical somatosensory evoked potentials after median or ulnar nerve stimulation were recorded in 21 patients with cervical spondylosis with radiculopathy or myelopathy. The test was normal when pain and paraesthesias were the only symptoms, while pathological in radiculopathy with objective neurological signs. The results varied in patients with cervical myelopathy.
متن کاملSomatosensory evoked potentials following nerve and segmental stimulation do not confirm cervical radiculopathy with sensory deficit.
Twenty eight patients with unilateral cervical radiculopathy were studied by somatosensory evoked potentials (SEPs) from nerve stimulation at the wrist and from skin stimulation at the first, third or fifth finger depending on the root involved. In order to evaluate the reliability of various "radicular SEP patterns" as described in the literature, absolute latencies and side-to-side difference...
متن کاملSpinal somatosensory evoked potentials in patients with tethered cord syndrome.
We studied the electrophysiological changes occurring in six patients with tethered cord syndrome. Evidence of spinal malformations was provided by magnetic resonance imaging. The functional assessment of the spinal cord was performed by analysing both spinal and cortical somatosensory evoked potentials. The evoked electrospinogram was recorded from the thoracic and lumbosacral spinous processe...
متن کاملCorrelation of Transcranial Color Doppler to N20 Somatosensory Evoked Potential Detects Ischemic Penumbra in Subarachnoid Hemorrhage
BACKGROUND Normal subjects present interhemispheric symmetry of middle cerebral artery (MCA) mean flow velocity and N20 cortical somatosensory evoked potential (SSEP). Subarachnoid haemorrhage (SAH) can modify this pattern, since high regional brain vascular resistances increase blood flow velocity, and impaired regional brain perfusion reduces N20 amplitude. The aim of the study is to investig...
