Filter by:Also known as a "moving itch", knismesis is a mildly annoying sensation caused by a light movement on the skin, such as from a crawling insect. Its underlying mechanism rely on spatial summation, i.e. amplification of the signal due to summation of stimulated fields, like it is for dynamic allodynia in neuropathic pain. This physiological study aims at determining the physical factors of the cutaneous stimulation inducing knismesis as well as the effect of confounding factors. The main area of exploration will be the back, because of its size and the possibility to blind the participant. The information collected, along with animal data in surrogate models, would help to better understand neuropathic pain in the future.
Children born with severe brain-based developmental disabilities frequently experience persistent unexplained periods of pain and irritability, often compounded by a limited capacity to communicate their distress. The investigators call this entity Pain and Irritability of Unknown Origin (PIUO). The rationale of this trial is to identify the clinical effect size of gabapentin in reducing and resolving pain in children with developmental brain disorders, specifically those with severe neurological impairment (SNI).
The purpose of the ESCAPE Study is to determine the extent to which epidural spinal cord stimulation (SCS) reduces arterial blood pressure (BP) in patients which chronic low back pain and hypertension. We also aim to determine the extent to which higher baseline BP (i.e., hypertension) predicts reductions in pain following SCS implant. This is an observational study of patients undergoing an implantation of a SCS device.
The purpose of this study is to assess the safety and effectiveness of MRI-guided focused ultrasound (MRgFUS) for treating Trigeminal Neuralgia. Trigeminal Neuralgia (pain) is a type of pain involving the face that can be disabling to those it affects.
The investigators designed the multicenter randomized parallel controlled clinical trial of electroacupuncture on PHN which is rigorously designed and have an appropriate sample size, aiming to evaluate the efficacy and safety of electroacupuncture in pain relieving and pain removing in the treatment of patients with PHN.
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.
Several studies have shown the efficacy of spinal cord stimulation in reducing the intensity of neuropathic pain. This efficacy is defined as obtaining relief of at least 50% of the preoperative pain intensity assessed by the visual analog scale or the digital pain scale. No study has evaluated the efficacy of stimulation specifically on the different components of neuropathic pain, only an overall improvement in pain has been described. A specific questionnaire for neuropathic pain has been extensively validated in neuropathic pain: the Neuropathic Pain Symptom Inventory (NPSI). Thanks to the multidimensional structure of this questionnaire, investigators propose to evaluate separately and in a much more specific way the efficacy of spinal cord stimulation in the short and long term on the different components of neuropathic pain and to define responders subgroups.
The purpose of this study is to investigate the incidence of intravascular injection during trigeminal nerve blocks.
Evaluation of the efficacy and tolerance of low doses of ethosuximide in the treatment of peripheral neuropathic pain
This is a Phase IIa randomized, double-blind, placebo-controlled study. The study objective is to investigate the efficacy and safety of repeat oral dosing of the investigational medicinal product (IMP) AP-325 for the treatment of peripheral post-surgical neuropathic pain (PPNP) after breast surgery (breast-conserving surgery, mastectomy, surgery to remove lymph nodes), chest surgery (e.g. thoracotomy, video assisted thoracoscopy and sternotomy), hernia repair of the abdominal wall (e.g. femoral hernia repairs, inguinal hernia repairs, umbilical hernia repair or incisional hernia repair), abdominal surgery (e.g. cholecystectomy, appendectomy but also see exclusion criterion 15), varicose vein surgery or gynecologic surgery (e.g. hysterectomy, C-section).
