Filter by:Current forms of pharmacologic and non-pharmacologic treatments for hypotension and orthostatic hypotension (OH) remain inadequate during acute inpatient rehabilitation (AIR) following a traumatic spinal cord injury (SCI). A critical need exists for the identification of safe, practical, and effective treatment options that stabilize blood pressure (BP) after traumatic SCI. Recent published evidence suggests that transcutaneous Spinal Cord Stimulation (TSCS) can be used to raise seated BP, and mitigate the falls in BP during orthostatic repositioning in individuals with chronic SCI. This site-specific project will focus on the use of TSCS to stabilizing seated BP and mitigate the fall in BP during orthostatic repositioning during AIR following traumatic SCI.
The primary objective of the study is to examine whether there is a difference in disability after 12 months of Spinal Cord Stimulation (SCS) in patients with Persistent Spinal Pain Syndrome Type 2 (PSPS T2) after receiving a standardized pain medication tapering protocol before SCS implantation, a personalized pain medication tapering protocol before SCS implantation, or no tapering protocol before SCS implantation. The secondary objective of the study is to examine whether there is a difference after 12 months of SCS in PSPS T2 patients after receiving a standardized pain medication tapering protocol before SCS implantation, a personalized pain medication tapering protocol before SCS implantation, or no tapering protocol before SCS implantation on pain intensity, health-related quality of life, participation, domains affected by substance use, anxiety and depression, medication use, psychological constructs, sleep, central sensitization, and healthcare expenditure.
Low back pain affects people of all ages and has become the leading cause of living with disability worldwide. Patients, suffering from persistent pain after spinal surgery in the absence of any clear spinal pathology are defined of having a "failed back surgery syndrome (FBSS)" and treatment of FBSS remains a great controversy in the spinal community. Apart from conservative treatment, spinal fusion remains as therapeutic option. Furthermore, minimal invasive Neuromodulation techniques might be a promising alternative. Aim of this randomized interventional multi center study is to compare treatment success in FBSS patients with either spinal cord stimulation (SCS) or fusion surgery, 12 months after intervention according to the Oswestry Disability Index (ODI) and other scales and scores. Radiological and health economic outcome also will be analysed for thorough comparison of techniques. Additionally, the safety of the interventions needs to be compared.
A multicenter randomized controlled trial will be conducted to evaluate whether the ability to work in Persistent Spinal Pain Syndrome Type II (PSPS-T2) patients after SCS implantation is different after a personalized biopsychosocial rehabilitation program specifically targeting return to work (RTW) compared with usual care.
Respiratory motor control deficit is the leading cause of morbidity and mortality in patients with spinal cord injury. The long-term goal of this NIH-funded study is to develop a rehabilitation strategy for respiration in patients with spinal cord injury as a standard of care. Respiratory function in patients with chronic spinal cord injury can be improved by using inspiratory-expiratory pressure threshold respiratory training protocol. However, the effectiveness of this intervention is limited by the levels of functional capacity preserved below the neurological level of injury. Preliminary data obtained for this study demonstrate that electrical spinal cord stimulation applied epidurally at the lumbar level in combination with respiratory training can activate and re-organize spinal motor networks for respiration. This study is designed to investigate respiratory motor control-related responses to epidural spinal cord stimulation alone and in combination with respiratory training. By characterization of respiratory muscle activation patterns using surface electromyography in association with pulmonary functional and respiration-related cardiovascular measures, the investigators expect to determine the specific stimulation parameters needed to increase spinal excitability below level of injury to enhance responses to the input from supraspinal centers that remain after injury and to promote the neural plasticity driven by the respiratory training. This hypothesis will be tested by pursuing two Specific Aims: 1) Evaluate the acute effects of epidural spinal cord stimulation on respiratory functional and motor control properties; and 2) Evaluate the effectiveness of epidural spinal cord stimulation combined with respiratory training.
There are a growing number of patients with refractory angina pectoris (RAP). RAP is defined as a 'chronic condition (> three months) characterized by diffuse coronary artery disease in the presence of proven ischemia, which is not amendable to a combination of medical therapy, angioplasty or coronary bypass surgery'. These patients are severely restricted in performing daily activities due to debilitating angina complaints, leading to a decreased quality of life. Spinal cord stimulation (SCS) is a last resort treatment option for patients with RAP. SCS is a device with a lead located in the thoracic epidural space and an Implantable Pulse Generator (IPG) in the abdomen or buttock that provides neurostimulation. Four possible mechanisms explaining the beneficial effects of SCS on RAP have been described: reduction of pain perception, decreased sympathetic tone, reduced myocardial oxygen demand, and improved coronary microcirculatory blood flow. Research into the effect of SCS on RAP up to date have mainly been observational studies, with only four placebo-controlled randomized controlled trials. All studies confirm that treatment with SCS leads to a reduction in the number of angina pectoris attacks. What is currently not clear, is whether there is a placebo effect as results vary between the studies. One study looked at the effect of SCS in patients with RAP on the reduction of ischemia (using MIBI-SPECT) with no control arm. After 12 months myocardial ischemia was reduced, but not after three months of treatment. Leading to the conclusion that the reduction is myocardial ischemia was not a direct effect of SCS, but rather due to better coronary collateralization. The 2020 ESC guideline 'chronic coronary syndromes' mentions non-existing to promising levels of evidence with regard to treatment options in patients with RAP and concludes that SCS may be considered (Class IIB; level of evidence B). It concludes that 'larger RCTs are required to define the role of each treatment modality for specific subgroups, to decrease non-responder rates and ascertain benefit beyond potential placebo effects'. The aim of the current randomized controlled trial (double-blind, cross-over, placebo-controlled, single center) is to determine if high density spinal cord stimulation, a paresthesia free form of stimulation, leads to a significant reduction in myocardial ischemia (using PET with Rubidium-82 as tracer) in patients with refractory angina pectoris. All patients included in this study will receive an implanted spinal cord stimulator after a positive TENS treadmill outcome and proven ischemia using the imaging modality PET with Rubidium-82 as tracer. Using a cross-over design all patients will have a 6 month period with high density stimulation and 6 month period of no stimulation. Randomization will determine in which order the patient receives these treatments. Both the patient and the treating physicians are blinded for this randomization process. At baseline a 6-minute walking test, the Seattle Angina Questionnaire, the RAND-36 questionnaire, the NRS scale and the CCS class will be performed/filled out. Cross-over takes place at 6 months (switch from high density stimulation to no stimulation or vice versa) prior to which the PET scan is repeated, as well as the 6-minute walking test, the Seattle Angina Questionnaire, the RAND-36 questionnaire, the NRS-scale and the CCS-class. At the end of the study period (12 months) the PET scan is repeated, as well as the 6-minute walking test, the Seattle Angina Questionnaire, the RAND-36 questionnaire, the NRS-scale and the CCS-class.
By combining the usual care of patients eligible for spinal cord stimulation (SME) with measurements of the HRV index (Heart Rate Variability), objective measurements of activity (number of steps, quality of sleep) and measurements of connectivity obtained by anatomical and functional magnetic resonance imaging (fMRI), the collection of preliminary data necessary for the analysis of markers correlated with the efficiency of stimulation will be possible. Ultimately, these markers could be used to optimize the perioperative management of these patients.
Recent findings have demonstrated that electrical stimulation to the spinal cord (i.e. implanted electrodes) can significantly recover bladder, bowel, and sexual function after injury. While promising, a major drawback is that individuals must undergo a highly invasive and expensive surgical procedure to implant the stimulator on top of the spinal cord. Moreover, the inability to re-position the implanted stimulator considerably limits the flexibility of this procedure. In this project, the investigators propose a comprehensive clinical study examining the effects of TCSCS in promoting recovery of these crucial functions in individuals with spinal cord injury (SCI). This non-invasive therapeutic modality uses electrodes applied over the skin to deliver electrical stimulation. It is based on the same principles of ground-breaking work from the investigator's group and others, showing that stimulation of the spinal cord can promote motor and autonomic (cardiovascular, bladder, bowel) recovery in individuals with chronic SCI.
