A patient with bladder frequency and urgency associated with pelvic pain had no control of symptoms by previous bladder distention, hysterectomy, or sacral nerve root stimulator. A clinical and neurophysiological diagnosis of pudendal neuropathy was made. Treatment with a nerve protection program and pudendal nerve perineural injections of local anesthetics and corticosteroids has provided tota...

At University College London implantable stimulators suitable for the selective stimulation of nerve are being developed. We hope these devices will be capable of selectively stimulating either by fibre position, fibre size or to launch action potentials in one direction only, using nerve cuff electrodes. These methods of selective stimulation have been demonstrated by many workers; early paper...

BACKGROUND AND OBJECTIVES Among the supraclavicular approaches to the brachial plexus, the subclavian perivascular technique is a well-established method of anesthesia of the upper extremity. Ever since Kulenkampf described his technique, eliciting a paresthesia has been almost mandatory ("no paresthesia, no anesthesia"). Lately, nerve stimulators have become more popular. However, up to the pr...

Obstructive sleep apnea (OSA) is more common in children with Down syndrome, affecting up to 60% of patients, and may persist in up to 50% of patients after adenotonsillectomy. These children with persistent moderate to severe OSA require continuous positive airway pressure, which is often poorly tolerated, or even tracheotomy for severe cases. The hypoglossal nerve stimulator is an implantable...

Implanted stimulators of motor nerve roots have been used for functional restoration in paraplegia since many years. While the high root density of the cauda equina limits the surgery to one field, it also presents the problem of cross-talk stimulation: unwanted activation of a root lying near an active set of electrodes. The Lumbar Anterior Root Stimulator Implant (LARSI) did exhibit cross-tal...

UNLABELLED BACKGROUND The widespread of hallux valgus surgery in a day care setting enhanced the role of regional anaesthesia in the last few years. Sciatic nerve block at popliteal fossa has been shown to provide safe and effective analgesia. Our purpose was to compare the success rate and performance time of popliteal block during resident's training for regional anaesthesia by using nerve...

The objective of this research was to demonstrate the potential of using peroneal nerve activity to derive timing control for stimulation in foot drop correction and to attempt recording and stimulation through the same electrode. Two subjects were implanted with cuff electrodes on the peroneal nerve. An input domain was derived from the recorded electroneurogram (ENG) and fed to a detection al...
