The anaesthetic management of children with glycogen-storage disease type IIa (Pompe's disease) presents a variety of challenges. A modification of a femoral nerve block, the inguinal paravascular block, as described by Winnie, was used in conjunction with intravenous ketamine to provide anaesthesia for a diagnostic muscle biopsy in a 5.5-month-old infant with Pompe's disease. A peripheral nerv...

A three dimensional inertial sensing system for measuring foot movements during gait is proposed and tested. It can form the basis for an automated tuning system for a two-channel implantable drop-foot stimulator. The foot orientation and position during the swing phase of gait can be reconstructed on the basis of three-dimensional measurement of acceleration and angular velocity, using initial...

BACKGROUND AND OBJECTIVES There are several approaches to the brachial plexus depending on the experience of the anesthesiologist and the site of the surgery. Posterior brachial plexus block may be an alternative for shoulder, clavicle and proximal humerus surgery. This study aims at presenting the results of patients submitted to posterior brachial plexus block with 0.5% ropivacaine and the ai...

BACKGROUND Long-term use of a foot-drop stimulator applying functional electrical stimulation (FES) to the common peroneal nerve improves walking performance even when the stimulator is off. This "therapeutic" effect might result from neuroplastic changes. OBJECTIVE To determine the effect of long-term use of a foot-drop stimulator on residual corticospinal connections in people with central ...

BACKGROUND AND PURPOSE Facial nerve stimulation has been proposed as a new treatment of ischemic stroke because autonomic components of the nerve dilate cerebral arteries and increase cerebral blood flow when activated. A noninvasive facial nerve stimulator device based on pulsed magnetic stimulation was tested in a dog middle cerebral artery occlusion model. METHODS We used an ischemic strok...

Güçlü B. Low-cost computer-controlled current stimulator for the student laboratory. Adv Physiol Educ 31: 223–231, 2007; doi:10.1152/ advan.00110.2006.—Electrical stimulation of nerve and muscle tissues is frequently used for teaching core concepts in physiology. It is usually expensive to provide every student group in the laboratory with an individual stimulator. This article presents the des...

OBJECTIVE Brachial plexus perineural blocks provide specific analgesia for upper limb surgery. We present our experience with ultrasound-guided supraclavicular brachial plexus perineural blocks for distal upper limb surgery. Although single-injection ultrasound-guided supraclavicular blocks have been reported, little is known about the advantages using this approach compared with nerve stimulat...

Chronic hypoventilation due to injury to the brain stem respiratory center or high cervical cord (above the C3 level) can result in dependence to prolonged mechanical ventilation with tracheostomy, frequent nosocomial pneumonia, and prolonged hospitalization. Diaphragm pacing through electrical stimulation of the phrenic nerve is an established treatment for central hypoventilation syndrome. We...
