Somatosensory evoked potential findings in ankylosing spondylitis.

OBJECTIVE Somatosensory evoked potential (SSEP) abnormalities were reported in patients with ankylosing spondylitis (AS). This study aimed to investigate SSEP abnormalities and its relation with clinical findings in AS patients. MATERIALS AND METHODS The study included 26 patients with AS and 17 age-matched health volunteers (Control for SSEP). Median nerve SSEP findings were normal in all AS...

Intra-operative somatosensory-evoked potential monitoring.

PURPOSE To evaluate the usefulness of intra-operative somatosensory-evoked potentials (SSEPs) in monitoring spinal cord status via the posterior tibial nerve. METHODS 84 men and 28 women aged 16 to 66 years (72% were aged 20 to 40 years) with spinal trauma (63 in the lumbar and 49 in the thoracic spine) underwent posterior instrumentation and fusion using bone grafts. All 63 patients with lum...

Topographic distribution of the tibial somatosensory evoked potential using coherence.

The objective of the present study was to determine the adequate cortical regions based on the signal-to-noise ratio (SNR) for somatosensory evoked potential (SEP) recording. This investigation was carried out using magnitude-squared coherence (MSC), a frequency domain objective response detection technique. Electroencephalographic signals were collected (International 10-20 System) from 38 vol...

Dermatosomal Somatosensory Evoked Potential Demonstration of Nerve Root Decompression After

Reductions in low back pain and referred leg pain associated with a diagnosis of herniated disc, degenerative disc disease or facet syndrome have previously been reported after treatment with a VAX-D table, which intermittently distracts the spine. The object of this study was to use dermatomal somatosensory evoked potentials (DSSEPs) to demonstrate lumbar root decompression following VAX-D the...
