Active clinical trials for "Neuralgia"

This study aims to evaluate the long term efficacy over 25 weeks of repeated sessions of magnetic transcranial stimulation of the motor cortex or prefrontal cortex on average pain intensity, quality of life, sleep, neuropathic symptoms, return to work, in patients with peripheral neuropathic pain. The medical device of study: transcranial magnetic stimulator (TMS).

This study is designed to answer the question of whether injection of the greater occipital nerve at its proximal origin, near the C2 vertebrae, using ultrasound guidance is effective in improving pain in human subjects. HYPOTHESES Ultrasound (US) guided greater occipital nerve (GON) injections are effective at a novel, proximal C2 location in live, human subjects, measured by improvement in visual analog scale (VAS) pain scores pre-injection compared to VAS scores 30 minutes post-injection, 2-weeks post-injection, and 1-month post-injection . Ultrasound (US) guided injection of the greater occipital nerve (GON) at a novel, C2 location is effective at improvement of both occipital neuralgia and cervicogenic headache demonstrated by improvement in visual analog scale (VAS) pain scores pre-injection compared to VAS scores 30 minutes post-injection, 2-weeks post-injection, and 1-month post-injection. We further hypothesize that the mean improvement in VAS scores at 1-month post injection will be greater than 2 units. Ultrasound (US) guided injection of the greater occipital nerve (GON) at novel, proximal C2 location in live, human subjects appears safe.

The present study aims to compare directly the efficacy of two noninvasive neurostimulation techniques : repetitive transcranial magnetic stimulation and transcranial direct electrical current of the motor cortex in patients with chronic lumbar radiculopathy on pain intensity.

The repetitive transcranial magnetic stimulation (rTMS) is used in pain treatment for several years. The aim of the study is to assess, in a rigorous scientific protocol, analgesic effect of the neuronavigated rTMS assisted by robotic arm on chronic neuropathic painful subjects. The crossover study is randomized, double blinded and controlled (sham rTMS) and it includes a large homogeneous population suffering of central neuropathic pain.

Aim of Investigation Methylene blue (MB) is a diaminophenothiazine with antioxidant, anti-inflammatory properties and with inhibitory effects on nitric oxide. The aim of this study was to determine the clinical effectiveness of MB in the treatment of neuropathic pain. Methods Ten patients with neuropathic pain were randomized to receive one of the two treatments: methylene blue (MB1) 2 mg/kg (10 mg/mL Methyltioninklorid, Apoteket, Umeå, Sweden) or methylene blue (MB2) 0.02 mg/kg. Both MB solutions were infused intravenously over 60 minutes. The sensory function and the pain were evaluated at baseline and at 60 min after the start of infusions. A pain journal was kept by the patients in the following 5 days. Plasma and urinary concentrations of 8-isoprostane-prostaglandin F2α (8-iso-PGF2α) an indicator of oxidative injury, were measured with radioimmunoassay (RIA). A panel of 92 proteins biomarkers were determined with Proximity Extension Assay (PEA) prior and after infusions. comparison with the control group. MB infusion produced an enhancement of prolactin.

A randomized double-blind controlled two centers study. The primary objective of this study will be to show a superiority of hypnosis over relaxation on pain intensity in patients with neuropathic pain.

The purpose of this study is to assess the effectiveness of craniofacial nerve stimulation for the treatment of neuropathic pain.

Objective: To investigate the effects of a cognitive behavioural intervention targeting specific fears in patients with painful diabetic neuropathy, on physical activity and quality of life.

Electrical stimulation of the spinal cord (Spinal Cord Stimulation or SCS) for pain relief has been used for decades. It is used most commonly in patients with chronic neuropathic leg pain, after spinal surgery. Conventional neurostimulation is applied in frequencies of 30 to 60 Hertz (Hz) and perceptible paraesthesias are felt. Stimulation using higher frequencies with sub perception paraesthesias has recently challenged the conventional form of neurostimulation.The high frequency stimulation appears to show better pain relief for both back and limb pain in comparison to low frequency SCS, and may also to be effective in some subjects who did not respond to low frequency SCS.
