In order to be able to study the effects of evoked fields with magnetoencephalography (MEG) in two groups of patients, comparison is made with a group of healthy volunteers.
This study is directed at the (central and / or peripheral) mechanisms of pain and the cortical changes (plasticity) due to chronic non-malignant pain in two groups of patients and one healthy volunteer group.
The aim of the study is further to evaluate cortical processes by MEG (and fMRI, if feasible) to quantify and qualify the responses, localise the generators and study the effects of a pain therapy.
To search for patterns that may result in diagnostic criteria and have an indicative value for the treatment and the monitoring of the effects.
Finally the study not only intends to support clinical diagnosis but also to provide tools to monitor treatment and support the choice (algorithm) between SCS and SAN. An algorithm, facilitating decision making between these two treatments, will be promoted. It should also provide a clinical decision tool for the use of SAN

The aim of the present study was to investigate the sensitivity of AEP (auditory evoked potentials) to muscular artefacts using sedation and local anesthesia.
The purpose of this study is to compare the efficiency and safety of 2ml versus 5ml of local anesthetics used in stellate ganglion blocks for the treatment of complex regional pain syndrom...
The aim of this interventional study is to find out the incidence of sore throat among intubated patients in Jordan university hospital and to find out which is preventive and effective me...
In vitro studies suggest that low levels of amplitude-modulated electromagnetic fields may modify cell growth. We have identified specific frequencies that may block cancer cell growth. We...
To investigate possible effects of radio frequency electromagnetic fields on EEG activity during sleep and on Brain function during wake (EEG in the resting state condition, slow EEG poten...
Lumbar epidural block is an effective and routinely used technique for labor pain relief, and the combined spinal-epidural block has the benefit of using lower doses of local anesthetics and rapid ons...
Slow periodic activity can propagate with speeds around 0.1 m/s and be modulated by weak electric fields. Slow periodic activity in the longitudinal hippocampal slice can propagate without chemical sy...
Perineural dexamethasone has been shown to prolong the duration of local anesthetic (LA) effect in regional anesthesia; however, the use of perineural dexamethasone as an adjuvant to to the transversu...
The speed of local anesthetic (LA) injections in peripheral regional anesthesia ranges from slow continuous infusions (3-12 mL/h) to rapid manual injections (>7500 mL/h). Optimizing injection speed co...
Skin thermal changes modulate itch sensitivity. However, the mechanisms of this modulation are still unclear. Using mouse models of acute and chronic itch, we investigated whether local innocuous ther...
The measurement of magnetic fields over the head generated by electric currents in the brain. As in any electrical conductor, electric fields in the brain are accompanied by orthogonal magnetic fields. The measurement of these fields provides information about the localization of brain activity which is complementary to that provided by ELECTROENCEPHALOGRAPHY. Magnetoencephalography may be used alone or together with electroencephalography, for measurement of spontaneous or evoked activity, and for research or clinical purposes.
Interruption of sympathetic pathways, by local injection of an anesthetic agent, at any of four levels: peripheral nerve block, sympathetic ganglion block, extradural block, and subarachnoid block.
The recorded electrical responses from nerve, muscle, SENSORY RECEPTOR, or area of the CENTRAL NERVOUS SYSTEM following stimulation. They range from less than a microvolt to several microvolts. The evoked potential can be auditory (EVOKED POTENTIALS, AUDITORY), somatosensory (EVOKED POTENTIALS, SOMATOSENSORY), visual (EVOKED POTENTIALS, VISUAL), or motor (EVOKED POTENTIALS, MOTOR), or other modalities that have been reported. Often used synonymously to event-related potentials which are associated with higher level cognitive processes.
A local anesthetic of the ester type that has a slow onset and a short duration of action. It is mainly used for infiltration anesthesia, peripheral nerve block, and spinal block. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1016).
The electric response evoked in the CEREBRAL CORTEX by stimulation along AFFERENT PATHWAYS from PERIPHERAL NERVES to CEREBRUM.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
An anesthesiologist (US English) or anaesthetist (British English) is a physician trained in anesthesia and perioperative medicine. Anesthesiologists are physicians who provide medical care to patients in a wide variety of (usually acute) situations. ...
Pain is defined by the International Association for the Study of Pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage”. Some illnesses can be excruci...
