Catering Service of High-Speed Railway (CSHR) starts at suppliers, includes distribution centers and service stations in cities, and ends at cabinets in high-speed trains. In Distribution System Design (DSD) Problem for CSHR, it is critical to evaluate the alternatives of service stations, which is termed as Service Station Evaluation Problem in Catering Service of High-speed Railway (SSEP-CSHR...

BACKGROUND The CNS manifestations of the antiphospholipid syndrome (APS) can mimic multiple sclerosis both clinically and radiologically. OBJECTIVE To compare evoked potential studies in APS patients and patients with multiple sclerosis with similar neurological disability. METHODS 30 APS patients with CNS manifestations and 33 patients with definite multiple sclerosis and similar neurologi...

Somatosensory evoked potential (SSEP) recordings from the scalp were performed in 17 healthy subjects. In seven of these SSEP was also recorded at the level of the second lumbar spine. In the other ten F and H responses and the corresponding M responses were studied. By means of the SSEP recordings at the level of the second lumbar spine and the F- and H-responses, the conduction time in the br...

In order to clarify the effects of local vibration on the peripheral and central nervous system, peripheral (median) nerve conduction velocities and short-latency somatosensory evoked potentials (SSEP) following stimulation of the median nerve at the wrist were measured in 15 male forest workers in 1986. They had engaged in chain-saw operation for 16-34 (mean 22) years; their working days in 19...

OBJECTIVES/HYPOTHESIS Continuous intraoperative neuromonitoring (IONM) of transcranial electric motor evoked potentials (tceMEPs) and somatosensory evoked potentials (SSEPs) has gained universal acceptance as an efficacious method for detecting emerging positional brachial plexopathy or peripheral nerve compression during spinal and shoulder surgery. This has implications for transaxillary thyr...

We have studied the effects of an i.v. bolus of thiopentone 4 mg kg-1 on the median nerve somatosensory evoked potentials (SSEP) in 15 unpremedicated patients. The latency and amplitude of the SSEP response over the second cervical vertebra (SC) and sensory cortex (P15, N20, P25) were recorded before and for 12 min after injection. Data were analysed at 0, 4, 8 and 12 min for time-related alter...

We report a case of cervicomedullary compression by an anomalous vertebral artery treated using microsurgical decompression with intraoperative monitoring. A 68-year-old woman presented with posterior neck pain and gait disturbance. MRI revealed multiple abnormalities, including an anomalous vertebral artery that compressed the spinal cord at the cervicomedullary junction. Suboccipital craniect...

Objective. To study the correlation between neurological, immunological and neurophysiological signs of paraneoplastic polyneuropathy (PPNP) caused by small cell lung cancer (SCLC), to improve quality diagnosis this pathology. Materials methods. Clinical, (anti-Hu) (electromyography (EMG), electroneuromyography (ENMG), somatosensory evoked potentials (SSEP)) examination 61 patients with PPNP SC...

We investigated the role of ipsilateral ascending pathways in the neural coupling underlying cooperative hand movements of stroke subjects. Ipsi- and contralateral somatosensory evoked potentials (SSEP) were recorded following ulnar nerve stimulation during cooperative and non-cooperative hand movements. The amplitude ratio, that is, ipsilateral divided by contralateral amplitude, was highest d...
