Active clinical trials for "Neuralgia"

The purpose of this study is to gain initial safety and efficacy data on the experimental agent REN-1654 in patients with painful post-herpetic neuralgia (PHN).

This study will look into the effectiveness of spinal cord stimulation (SCS) in reducing chronic neuropathic pain in patients who have not had previous spinal surgery. This will be assessed by comparing the Numerical Rating Scale (NRS) questionnaire responses before and after the SCS intervention. We will also investigate the effect of HD frequency parameters on the improvement of quality of life, sleep and any adverse events following the spinal cord stimulation.

Rationale: In 2016, Henssen et al. discuss that orofacial pain may be conducted in a bilateral fashion, inducing activation of both thalami [1]. For this reason, bilateral stimulation of the motor cortex is thought to induce a stronger analgesic effect compared to unilateral motor cortex stimulation by transcranial magnetic stimulation. Objective: To investigate the superiority of bilateral transcranial magnetic stimulation (TMS) over unilateral TMS of the motor cortex Study design: Double-blind, randomized controlled trial Study population: Patients that suffer from chronic orofacial pain and have not been treated (yet) with any form of neuromodulation. Intervention (if applicable): One group receives bilateral TMS whereas the other group receives unilateral TMS for one month. After one month, the groups switch treatment protocol. Main study parameters/endpoints: Modification in intensity of pain as measured using the VAS, the influence the relief of pain with regard to quality of life and daily activities using the McGill Pain Questionnaire. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Time investment of patients.

Transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) will be applied for patient who suffer from neuropathic pain following spinal cord injury The tDCS treatment will be coupled with a video of a man walking (creating a visual illusion) in order to enhance functional ability and reduce pain

To determine the time-course of plasma and CSF concentrations of intravenous (IV) ondansetron in healthy subjects, with and without selective inhibition of Pgp efflux transporter.

The purpose of this study is to evaluate the Efficacy and safety of pregabalin sustained release tablet versus placebo for postherpetic neuralgia.

Chronic cervicobrachialgia is a public health problem. Epidural injections of corticosteroids and local anesthesics via transforaminal and interlaminar routes both have shown their potential in its treatment. The interlaminar approach offers the advantage of an epidural injection (i.e., direct contact with the nerve root in the epidural space). However, it requires fluoroscopy and can lead to potentially serious complications (compression of the nerve root, spinal cord injury...). The ultrasound-guided injection of corticosteroids via the transforaminal route, which offers the advantage of selectively targeting the symptomatic nerve root, may have the same therapeutic advantages as the interlaminar approach in decreasing unilateral cervicobrachial pain (i.e. a decrease in pain after infiltration) and reduce its risks.The aim of this study is to compare the efficacy of transforaminal vs interlaminar cervical corticosteroid injection.

Feasibility study with 25 patients investigating the effect of cryoneurolysis on persistent cutaneous neuropathic pain after surgery and trauma. All patients receive active treatment (cryoneurolysis). The study design is unblinded, non-randomized, non-controlled.

This is a single-cohort, prospective, observational study evaluating the effects of gabapentin on cognition. The goal of the study is to determine whether there is a measurable change in cognitive function from baseline in patients who are prescribed gabapentin for the treatment of neuropathic pain.

The primary outcome is to compare the analgesic efficacy of intravenous ketamine treatment to that of a placebo in patients with refractory neuropathic pain. The secondary outcomes are: - To compare the additive analgesic efficacy of prior administration of magnesium sulfate to that of placebo and ketamine only, on the effectiveness of intravenous ketamine treatment, - To study the evolution time of pain and analgesia after the intravenous administration of ketamine and placebo, - To study the correlation of the analgesic response to administered products respectively ketamine, ketamine and magnesium sulfate, placebo.
