Filter by:The purpose of this study is to demonstrate safety and efficacy of a new spinal cord stimulation paddle electrode which is able to target the dorsal horns, dorsal nerve roots, and dorsal columns. The research electrode ("Study Electrode") is designed to answer basic physiological clinical research questions. It may inform future device therapy development, but the Study Electrode is not a product that will be marketed or sold. The Investigators believe the protocol is a Non-Significant Risk study answering basic physiological research questions, which may be performed under hospital IRB approval.
In the past decade, spine surgery rates have dramatically increased in parallel to those of other procedural interventions. Persistent pain is a common occurrence after spine surgery, with the most commonly quoted prevalence rates ranging from 10% to 40%. This pain can be classified into failure to alleviate baseline pain, pain resulting from complications (e.g., arachnoiditis and epidural adhesions), and pain that ensues several years later as a sequele to alterations in spinal architecture and biomechanics (e.g., adjacent segment discogenic or facetogenic pain) which is called failed back surgery syndrome ( FBSS )
The goal of this study is to evaluate whether a new spinal cord stimulation paradigm, called Coordinate Reset (CR) Stimulation, can provide equivalent or better pain relief with reduced energy requirements. The investigators will test this new stimulation paradigm in patients who are already undergoing spinal cord stimulation surgery. The investigators will also study whether there are changes in electroencephalography (brain waves) associated with this new stimulation paradigm. The investigators hope to learn whether CR stimulation can provide equivalent or better pain relief with reduced energy requirements. They also hope to learn whether there are changes in brain function with effective CR stimulation compared to conventional stimulation. This study will be testing a specific stimulation paradigm in people who have already consented to have spinal cord stimulation performed for treatment of their chronic pain.
The purpose of this study is to reveal the effectiveness and satisfaction of integrative Korean medicine for Failed Back Surgery Syndrome(FBSS) by observation patients treated with integrative Korean medicine. This study is a prospective observational study. The subjects for study are patients diagnosed with Failed Back Surgery Syndrome(FBSS) and who have been admitted to Gangnam Jaseng Hospital of Korean medicine and Bucheon Jaseng Hospital of Korean medicine for 2011.11-2014.09. Medical records of selected patients will be analyzed, and telephone surveys will be conducted for each patient. The survey questions are Numeric rating scale (NRS), Oswestry disability index (ODI), quality of life, and Patient Global Impression of Change (PGIC), etc.
Prospective multicentric observational trial on caregiver burden, caregiver satisfaction and clinical outcome in spinal cord stimulation for chronic neuropathic pain.
Chronic pain is correlated with alterations in the structure and function of the brain, developed according to the phenotype of pain. Still today, the data on functional connectivity (FC), on chronic back pain, in patients with failed back surgery syndrome (FBSS), is limited. The selection process for the ideal candidate for spinal cord stimulation (SCS) is based on results from test and functional variables analysis as well as pain evaluation. In addition to the difficulties in the initial selection of patients and the predictive analysis of the test phase, which undoubtedly impact on the results in the middle and long term, the rate of explants is one of the most important concerns, in the analysis of suitability of implanted candidates. The hypothesis is that the structural and functional quantitative information provided by imaging biomarkers will improve the characterization of the patients compared to the characterization with the current clinical variables alone and this will allow establishing a CDSS that improve the effectiveness of the SCS implantation, optimizing human, economic and psychological resources. A prospective, consecutive and observational, open-label, single-center study conducted at the Multidisciplinary Pain Management Department of our University Hospital. A total of 69 subjects were initially included in the study. The population split in 3 groups: - Interventional Group-SCS, included 35 patients with failed back surgery syndrome (FBSS) who were treated with SCS implants. - Comparator group included 23 patients with patients with chronic low-back pain who were treated with conventional medication (CM) for their pain. - Control Group included 11 subjects as health controls who volunteered to participate in the study. MR images were obtained in a 1.5T MR system (Ingenia, Philips, Best, The Netherlands) using an 8-channel head coil.Clinical variables were evaluated at two different time points baseline and 12 months after SCS implantation or conventional medication. An ad hoc database was created to evaluate the different variables involved in pain , including sociodemographic variables (age, gender, level of studies and marital status), clinical variables (anxiety, depression, sleeping hours, resilience, NRS, the Pain Detect Questionnaire (PD-Q)) , and the images obtained from the fMRI.
Doctors sometimes treat chronic pain with devices that send mild electrical currents into the spinal cord. This type of treatment is referred to as neurostimulation. A common form of neurostimulation therapy is spinal cord stimulation (SCS). In this study, researchers want to learn more about how SCS affects pain processing and relieves pain. The researchers will examine multiple forms of SCS in chronic pain patients who are receiving SCS from their own doctors as part of their standard of care. During the study, participants will be asked to complete a variety of evaluations at certain time points.
In spinal cord stimulation (SCS), most outcome data are based on patient questionnaires. The lack of tools for objective evaluation of the effects of SCS on chronic pain has posed a barrier for providing solid proof of the therapy. Currently, however, SCS-devices with an accelerator included are available on the market. The position orientation data provided by the neurostimulator therefore gives new possibilities for objective measurement of gross activity in daily life.
