Active clinical trials for "Failed Back Surgery Syndrome"

Prospective, randomized, multicentre, parallel, controlled, and double-blind trial. It is a study with 2 groups with evaluation pre and post treatment with Spinal Cord Stimulation (SCS) implantation of patients with Failed Back Surgery Syndrome (FBSS). The study has been designed to assess primarily non-inferiority and secondarily superiority of SCS DTM therapy

Spinal Cord Stimulation (SCS) has been a well-established treatment for chronic neuropathic pain in Failed Back Surgery Syndrome with associated legs and/or low back pain. The waves used in Spinal Cord Stimulation are mainly Tonic or Burst. Both Tonic and Burst stimulation offer neuropathic pain suppression, with slightly superiority of the Burst wave for the FBSS. The aim of our study is to evaluate the efficacy of a new stimulation paradigm with the combination of the two wave forms.

Spinal cord stimulation (SCS) is one of the most commonly undertaken neuromodulatory surgery techniques in the treatment of neuropathic pain. The indication for SCS is an ineffective conservative treatment of chronic pain syndromes. The effectiveness of SCS in the case of neuropathic pain is high. The positive result of SCS treatment is the reduction of previous painful symptoms by min. 50% and / or a reduction in the amount of taken analgesics and an improvement in the quality of life including sleep quality. Long-term studies estimate that in a properly selected group of patients more than 50% of patients achieve pain reduction by the required 50% and about 60% - 70% have an improvement in the quality of life and a reduction of pain. The efficacy of SCS in different modes of stimulation is evaluated. Patients receive four different types of stimulation for 2-week period - not knowing what kind of stimulation it is. It is said that in one type of stimulation they would feel parestesias and in other three they would not. Patients are not informed that beside tonic, burst and high frequency stimulation, the fourth is an off stimulation to check for placebo effect. The test is double-blinded

18-SMI-2013 is a post market, observational, questionnaire based study to assess the effectiveness of the commercially available Axium neurostimulator in the management of chronic pain following lumbar discectomy (Failed Back Surgery Syndrome)

The study investigates the feasibility and efficacy of Transcutaneous Electrical Nerve Stimulator (TENS) in a subgroup of patients with neuropathic pain. Those patients are suffering of neuropathic pain at the lower back and leg after spinal surgery with a predominance of pain in the leg.

The purpose of this study is to characterize the pain coverage capability of the RESTORE spinal cord stimulation (SCS) and assess health outcomes.

The purpose of this study is to reveal the effectiveness and safety of integrative Korean medicine for Failed Back Surgery Syndrome(FBSS) by observing inpatients treated with integrative Korean medicine. This study is a retrospective observational study. The subjects for study are patients diagnosed with FBSS and who have been admitted to four Jaseng Hospital of Korean medicine (Gangnam, Bucheon, Daejeon, and Haeundae) for 2015.01.01-2019.12.31. Medical records of selected patients will be analyzed, and telephone surveys will be conducted for each patient. The survey questions are Numeric ratinc scale (NRS), Oswestry Disability Index(ODI), quality of life, and Patient Global Impression of Change (PGIC), etc.

In this study, a retrospective analysis will be performed on collected data of 14 patients with Failed Back Surgery Syndrome, treated with Spinal cord stimulation. In separate studies, fMRI and EEG recordings were made in resting state conditions on two time points. The fMRI assessments and EEG recordings were performed before the SCS implantation (baseline) and repeated around 3 months after the definitive SCS implantation. During both assessments, patients were asked to fill in a VAS diary for their leg and back pain (scores from 0 to 10). The aim of the current retrospective study is to correlate the clinical data obtained from the VAS scores, with estimates of effective connectivity (obtained from fMRI and EEG). Effective connectivity will be calculated by using dynamic causal modeling (DCM) on the baseline data and the data obtained 3 months after SCS. The aim is to evaluate whether DCM data of EEG is equally/worse/better correlating with the clinical data as DCM data of fMRI.

This study is an observatory single center study investigating heart rate variability during on and off states of the spinal cord stimulator, in patients with failed back surgery syndrome.

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.
