Active clinical trials for "Neuralgia"

This study is designed to measure how common nerve abnormalities are within a group of patients who feel discomfort within their eyes.

The overarching aim of this study is to investigate the contribution of peripheral afferent input to spontaneous and evoked central neuropathic pain after a spinal cord lesion or disease.

The purpose of this study is to investigate if 28 days of treatment with AZD2066 compared to placebo can relieve the pain arising from the nervous system when the patients are touched by something that should not cause pain or have severe pain when they are touched by something that should only cause a little pain.

Little is known about pain-related outcomes experienced by patients in the first few weeks after surgery, once they are discharged from hospital. This study aims to characterize pain, pain-related interference, and early neuropathic pain in the sub-acute phase after surgery.

IncobotulinumtoxinA (Xeomin®) is a neurotoxin which inhibits the release of certain chemicals at the nerve terminals. It blocks cholinergic transmission at the neuromuscular junction by inhibiting the release of acetylcholine from motor neurons. In addition it blocks the release of Substance P (SP) and Calcitonin Gene Related Peptide (CGRP) from C fibers involved in pain perception. This study is designed to see if Xeomin® is superior to placebo in the treatment of medically refractory trigeminal neuralgia (TN). Subjects will be asked to maintain an attack diary throughout the study. They will also be asked to attend 4 office visits; Visit 1- Screening Visit, Visit 2- Injection Visit, Visit 3- Follow-Up Visit and Visit 4- Final Visit. At the end of the study the active (Xeomin®) and placebo groups will be compared to see if one group had better relief than the other.

The aim of this study is to answer the questions below; Is there a difference between patients with lumbar radiculopathy suffering from radicular pain and healthy subjects in terms of static and dynamic postural stability? Is there a relationship between postural stability and the neuropathic characteristics of radicular pain?

This study is an open-label study to determine the feasibility of Motor Cortex Stimulation (MCS) in the treatment of patients with chronic pain of the face or upper extremity. MCS will be delivered by use of an electrode and pulse generator, which are FDA approved for spinal cord stimulation but are not approved for MCS. The study has as a single-arm design with the subject at baseline serving as a control for the response to MCS.

This study is an open-label, multicenter, extension study for subjects who completed NeurogesX Study C111 and received treatment with NGX-4010 (Capsaicin Patch) within 12 weeks (up to +7days) before entry into Study C114

In order to address the growing problem of chronic pain management in the UK, a proof of concept/feasibility open label cohort study has been devised to explore the effectiveness of a home-based self-administered non-pharmacological treatment utilising neurofeedback (NFB) training with a headset and tablet-based software application. This study will replicate the intervention from a previous clinical trial conducted in the UK during the Covid-19 lockdown in 2020/21 (NCT04418362) and extend it by examining EEG activity before, during, and after the intervention, alongside outcome measures, including changes in pain intensity and severity, sleep, mood and quality of life. Ten participants will take part in pre-intervention assessments followed by four weeks of EEG baseline readings (5 times per week for 5 minutes), eight weeks of NFB treatment (5 times per week for 40 mins), and 12 weeks of post treatment EEG baselines readings (5 times per week for 5 minutes). Participants will be provided with training and detailed instructions on how to self-administer the NFB treatment using a bespoke headset and tablet-based software application in the comfort of their own homes. Assessments will be conducted at Week 0 (pre-intervention), Week 4 (pre-NFB treatment), Week 12 (post NFB treatment) and at follow up points (Week 16, 20, and 24). It is anticipated this study will provide evidence of the safety, efficacy, reliability and validity of a low-cost non-pharmacological solution to the physical, psychological and social difficulties experienced by individuals with chronic neuropathic pain conducted within the NHS health system.

Shoulder, neck, back and temporal pain and herpes zoster pain are neuropathic pain. Preliminary clinical studies have confirmed that injection of freshly prepared HA35 can relieve neuropathic pain. This clinical study is a prospective repeated experiments. The purpose of this study was to verify the effectiveness of HA35 injection therapy.
