These data may aid in the development of alternative mechanisms for electrical stimulation for patients with medically intractable seizures and add to our knowledge regarding the mechanism for seizure cessation following peripheral nerve stimulation. Additionally, the effects of right-sided vagus nerve stimulation on induced spinal cord seizures involve descending spinal pathways. As with left-sided vagus nerve stimulation, right-sided vagus nerve stimulation results in cessation of induced spinal cord seizures. Transection of the spinal cord superior to the site of seizure induction resulted in the ineffectiveness of vagus nerve stimulation in causing cessation of seizure activity in all study animals. Right-sided vagus nerve stimulation resulted in cessation of spinal cord seizure activity in all animals. Following multiple stimulations of the vagus nerve and with seizure activity confirmed, the cord was transected in the midthoracic region and vagus nerve stimulation performed. With the exception of the control animal, once seizure activity was discernible via motor convulsion or increased electrical activity, the right vagus nerve previously isolated in the neck was stimulated. Topical penicillin, a known epileptogenic drug to the cerebral cortex and spinal cord, was next applied to the dorsal surface of the exposed cord. Four pigs were anesthetized and placed in the lateral position and a small laminectomy performed in the lumbar region. To test our hypothesis that right-sided vagus nerve stimulation will also abort seizure activity, we have initiated seizures in the spinal cord and then performed right-sided vagus nerve stimulation in an animal model. We have previously shown that left-sided vagus nerve stimulation results in cessation of induced spinal cord seizures.

An implanted spinal cord stimulator for pain relief is a device that is used to stimulate electrically a patient's spinal cord to relieve. Psychological intervention may have a preventative role for those who are deemed at high risk of Twiddler's syndrome from initial psychological screening.Ģ1 CFR 882.5880 - Implanted spinal cord stimulator for pain relief. This may be achieved by implanting the IPG in the lumbar region subcutaneously above the belt line. ![]() Awareness and identification of Twiddler's syndrome may help prevent its occurrence and further revisions. Hardware failure is not uncommon in spinal cord stimulation. To the best of our knowledge this is the first reported series of Twiddler's syndrome with implantable pulse generators (IPGs) for spinal cord stimulation. Imaging revealed repeated rotations and twisting of the wires of the spinal cord stimulators leading to hardware failure. ![]() Presentation ranged from 4 to 228Â weeks after implantation. Three patients with Twiddler's syndrome were identified. Over the 5-year study period, all consecutive cases of spinal cord stimulation failure were studied. Our unit implants on average 110 spinal cord stimulators a year. The diagnostic criterion for Twiddler's syndrome is radiological evidence of twisting of wires in the presence of failure of spinal cord stimulation. Data were collected retrospectively between 20 for all patients presenting with failure of spinal cord stimulators. The aims are to present a case series of Twiddler's syndrome in spinal cord stimulators with analysis of the possible mechanism of this syndrome and discuss how this phenomenon can be prevented.
