Filter by:The investigators will be evaluating quality of life outcomes in patients who are undergoing routine spinal cord stimulator implant for uncontrolled pain. Patients will be evaluated pre and post-operatively for quality of life improvements, pain control, and functionality.
Transcranial Direct Current Stimulation (tDCS) is a noninvasive brain stimulation technique that utilizes low amplitude direct currents applied via scalp electrodes to apply currents to the brain and modulate the level of cortical excitability. tDCS applied over the dorsolateral prefrontal and motor cortex has been reported to be able to decrease pain sensation and to increase pain threshold in healthy subjects and is effective in reducing central chronic pain in patients with multiple sclerosis (PwMS.) In spite of the encouraging results of tDCS in PwMS, detailed mechanisms accounting for its analgesic effect have not yet been elucidated. This will be the first study to determine the effects of tDCS on whole and regional brain activity in PwMS with neuropathic pain to identify potential mechanisms of the analgesic effects of tDCS. These findings will provide targets for future studies investigating different stimulation areas, possible short- and long-term side effects, and specific target areas for other precise stimulation techniques such as transcranial magnetic stimulation.
This study was designed to characterize dose response, and evaluate safety and efficacy of three different doses of EMA401 compared to placebo in patients with post-herpetic neuralgia (PHN).
The primary objective of the study is to evaluate the long-term safety and tolerability of BIIB074 in participants with neuropathic Pain From Lumbosacral Radiculopathy (PLSR). A secondary objective is to investigate the maintenance of effect during long-term treatment with BIIB074 in participants with neuropathic PLSR. For all efficacy assessments, baseline will be prior to randomization into Study 1014802-203. Another secondary objective is to evaluate the impact of treatment with BIIB074 on quality of life (QoL).
The study aims to better understand how to program Spinal Cord Stimulation for the treatment of chronic low back and leg pain
This is a randomized study investigating whether identification, ligation, and burial of superficial branches of the saphenous nerve crossing the surgical field during total knee arthroplasty reduces the rate of post-operative anterior knee pain and neuralgia compared to standard total knee arthroplasty.
Neuropathic pain is a medical condition involving allodynia (painful perceptions in response to stimuli that normally are not) and spontaneous pain (occurring at rest, without stimulation). This pain is secondary to nervous system injury affecting the sensory system. The lesion is either at the nerve endings of the spinal cord or brain. It induces a loss of sensitivity and reorganization of brain activity. Previous studies in functional neuroimaging have focused on brain areas activated during allodynic stimuli compared to non-painful stimuli. The abnormalities have been reported, but it was not possible to conclude formally. The objective of this study is to understand the brain dysfunction that induces allodynic pain considering the deafferentation of each patient and possible cortical losses.

This pain is secondary to nervous system injury affecting the sensory system. The lesion is either at the nerve endings of the spinal cord or brain. It induces a loss of sensitivity and likely reorganization of brain activity that are causing pain and which are the subject of this study. Previous studies in functional neuroimaging has focused on brain areas activated during allodynic stimuli compared to non-painful stimuli. The abnormalities have been reported, but it was not possible to conclude formally. The authors failed to assess the part of the effect of the loss of sensory afferents (deafferentation) and the basal brain function. Indeed, the operation without any sensory stimulation is not known yet is the initial level of activity which is the benchmark for studying brain function during stimulation. The objective of this study is to understand what are the cortical systems of allodynic dysfunctional in patients compared with controls at baseline.
The purpose of this study is to realize a cartography of the allodynic and hypoasthetic territories associated with a neuropathic pain appearing in patients who underwent a Total Knee Arthroplasty (TKA)
Loxapine is an antipsychotic drug approved for the treatment of schizophrenia in several countries including the United States. In animal studies in mice, loxapine reduced neuropathic pain. Hence, in a proof-of-principle and dose-escalating study the tolerability and analgesic efficacy of loxapine will be evaluated in patients with neuropathic pain.
