Filter by:(Primary) 1. To compare the clinical effects and side effects of two different stimulation strategies that do not produce any sensory percept (1000 Hz and placebo) on clinical benefit for electrodes implanted for chronic pain as measured by the Visual Analog Pain Scale for back and leg pain, the Brief Pain Inventory, the SF-36, and the Pain Vigilance and Awareness Questionnaire. (Secondary) 2. To compare the clinical effects of the subthreshold (paresthesia-free) stimulation patterns with conventional (paresthesia-producing) stimulation patterns to evaluate the necessity of paresthesias and current amplitudes on clinical benefit for pain. 3. To identify the ability of subthreshold high-frequency to improve axial pain or the affective component of pain.
The purpose of this study is to evaluate the effect of pulse widths <500 µS and >1000 µS on clinical outcomes during a temporary SCS trial.
Spinal cord stimulation is a minimally invasive surgical treatment for severe, chronic, neuropathic pain that is refractory to conventional treatment. The treatment consists of an electrode implanted in the epidural space of the spinal cord, either via a percutaneous approach (using the so-called percutaneous leads) or via a surgical (hemi-) laminectomy (using the so-called surgical leads or plate leads). It is a well-known clinical observation that when activating or deactivating SCS stimulation, there is a variable interval before the patient perceives a clinical effect of the change. This variation goes by different names (carryover, echo, after effect, etc.) and might be dependent on the clinical condition and treatment duration. To our knowledge only very little research has been published on the topic of carryover effects; a recent study showed that the interval is highly variable between patients. While patients may experience immediate pain relief at the onset of SCS treatment, the effect in patients with a long-term SCS treatment history may have different characteristics, possibly due to ongoing changes in the nervous system. The aim of this pilot study is to lay the foundation for investigating the carryover effects in spinal cord stimulation. This will be carried out in a mixed population of patients with different indications for SCS, and with different treatment durations. Patients will be asked to deactivate their device via their remote control or with a magnet in a standardized fashion. They will be asked to reactivate the device when specific parameters have been met, and the time is recorded.
To assess lead migration rates using different methods of securing leads during Spinal Cord Stimulation trial period. Spinal cord stimulation has two phases. Trial, which is a precursor for a permanent implantation. Trial lasts less than a week, which gives the patient an opportunity to assess the effectiveness of the treatment.
The Implantable Systems Performance Registry (ISPR) was developed to evaluate the long-term reliability and performance of market-released Medtronic Neuromodulation infusion and stimulation products. Completion Notice: The ISPR was created by Medtronic to monitor the performance of commercially available products. This registry was initially designed to track performance of Medtronic's implantable infusion and spinal cord stimulation systems beginning in August 2003 and June 2004, respectively. Medtronic DBS Systems were added to the ISPR in June 2009, and Sacral Neuromodulation Systems in April 2010. Medtronic retired the ISPR in April 2016 and merged the data collected from this registry into the Product Surveillance Registry (PSR). Please refer to that record, Clinical Trials identifier: NCT01524276, for further information.
