Filter by:This study will apply low-intensity transcranial focused ultrasound to dorsal root ganglia in patients with chronic neuropathic pain. The target will be validated using magnetic resonance imaging. The stimulation will first be delivered using a range of stimulation parameters during psychophysical and physiological monitoring. A well-tolerated stimulation protocol will be selected for subsequent testing in a blinded randomized sham-controlled cross-over trial. The level of pain will be evaluated using the Numerical Rating Scale (NSR-11) and the Patient-Reported Outcomes Measurement Information System (PROMIS) numerical rating scales of pain.
In this study, the effect of nerve blockade and radiofrequency treatment applied to the nerve on pain in chronic migraine patients will be investigated. Occipital nerve blockade group (control group): Depending on the location of the pain, blockade will be applied unilaterally or bilaterally with 5 cc of 2% prilocaine for each sıde. Pulse Radiofrequency application to the greater occipital nerve will be applicated after radiofrequency cannula placed near the greater occipital nerve location with 42 degree, for 240 seconds.
This observational, prospective data collection is designed to evaluate the efficacy of CL-SCS therapy in real-world patients suffering from chronic pain.
The patient, who is experiencing chronic pain in the lower extremities persisting for more than three months, is scheduled to undergo lumbar sympathetic ganglion block. To evaluate the technical success of the sympathetic blockade, temperature and perfusion index (PI) will be measured at one-minute intervals over a 20-minute period before and after the procedure on the treated side and the opposite side foot. Additionally, other variables related to the procedure will be assessed before the procedure, after the procedure, before discharge, and during follow-up outpatient visits or phone surveys at 1 week and 1 month after the procedure.
Trigeminal neuralgia is one of the most common craniofacial neuralgias and one of the most severe types of facial pain, typically limited to the distribution of the trigeminal nerve. The first-line treatment for trigeminal neuralgia is medical therapy and primarily antiepileptic drugs. Various interventional and surgical methods can be used in patients who do not respond to medical treatment or who cannot tolerate side effects. Pulsed radiofrequency treatment of maxillary and mandibular nerves may provide longer-lasting pain relief in trigeminal neuralgia.This study aimed to investigate the clinical and demographic characteristics affecting treatment success in patients who underwent ultrasound-guided pulsed radiofrequency of the maxillary and/or mandibular nerves for trigeminal neuralgia.
Low back pain can persist in some patients with history of back surgery. In some cases, an increase in pain may even occur, and chronic pain may make treatment more difficult. A component of chronic pain is neuropathic pain, and its specific evaluation and treatment is important. Low back pain and radicular pain in the lower extremities are the main symptoms of failed back surgery syndrome (also called persistent spinal pain syndrome in new terminology). There are many methods for treatment of failed back surgery syndrome, such as analgesic medications, physical therapy, interventional pain treatment applications, and re-surgery options. Epidural pulsed radiofrequency therapy has recently become popular among interventional pain management procedures, and studies on its effectiveness are increasing. However, studies with a multifaceted approach that also evaluate neuropathic pain are lacking in the literature. In this study, it was planned to investigate the effect of epidural pulsed radiofrequency therapy on pain palliation, including neuropathic pain, in patients diagnosed with failed back surgery syndrome.
The proposed project aims to explore possible neuromodulatory effects of transcranial direct current stimulation (tDCS) on neuropathic pain caused by peripheral neuropathy. tDCS will be performed through an MRI-compatible stimulation setting during functional magnetic resonance imaging (fMRI) scanning. The stimulation target of tDCS will be the primary motor cortex (M1) and the dorsolateral prefrontal cortex (DLPFC). We expect that results from the current project will advance the understanding of neuromodulatory mechanisms of tDCS and facilitate the development of treatment strategies for patients with neuropathic pain.
Background: Chronic neuropathic pain associated with peripheral neuropathies cannot be attributed solely to lesions of peripheral sensory axons and likely involves alteration in the processing of nociceptive information in the central nervous system in most patients. Few data are available regarding EEG correlates of chronic neuropathic pain. The fact is that effective cortical neuromodulation strategies to treat neuropathic pain target the precentral cortical region, i.e. a cortical area corresponding to the motor cortex. It is not known how these strategies might modulate brain rhythms in the central cortical region, but it can be speculated that sensorimotor rhythms (SMRs) are modified. Another potent way of modulating cortical rhythms is to use EEG-based neurofeedback (NFB). Rare studies previously aimed at relieving neuropathic pain using EEG-NFB training. Methods/Design: The objective of this single-centre, single-blinded, randomized controlled pilot study is to assess the value of an EEG-NFB procedure to relieve chronic neuropathic pain in patients with painful peripheral neuropathy. A series of 32 patients will be randomly assigned to one of the two following EEG-NFB protocols, aimed at increasing either the low-β(SMR)/high-β ratio (n=16) or the α(μ)/θ ratio (n=16) at central (rolandic) cortical level. Various clinical outcome measures will be collected before and one week after 12 EEG-NFB sessions performed over 4 weeks. Resting-state EEG will also be recorded immediately before and after each NFB session. The primary endpoint will be the change in the impact of pain on patient's daily functioning, as assessed on the Interference Scale of the short form of the Brief Pain Inventory. Discussion: The value of EEG-NFB procedures to relieve neuropathic pain has been rarely studied. This pilot study will attempt to show the value of endogenous modulation of brain rhythms in the central (rolandic) region in the frequency band corresponding to the frequency of stimulation currently used by therapeutic motor cortex stimulation. In the case of significant clinical benefit produced by the low-β(SMR)/high-β ratio increasing strategy, this work could pave the way for using EEG-NFB training within the armamentarium of neuropathic pain therapy.
1. The correlations of serum vitamin D level, serum calcium level and osteoporosis degree with disease severity, treatment response, incidence of Post-Herpes zoster(PHN) and disease prognosis in Herpes zoster(HZ) patients were studied. 2. To investigate the role of inflammation-related factors and immune-related factors in the occurrence and development of HZ mediated by low vitamin D level.
This observational multicenter study aims to evaluate the reliability and validity of the e-tool for selecting patients eligible for SCS for chronic pain caused by one of the four etiologies listed above in the experience of daily clinical practice. The implantation procedure and devices used will be those used in the routine clinical practice of participating centers. Since the study is observational, the use of the e-tool will not replace the routine medical and psychological evaluation in participating centers before SCS implantation. Study Objectives: Primary Objective: Evaluate the degree of agreement/disagreement between the physicians opinion and the e-tool in selecting patients eligible for spinal cord stimulation for chronic pain. Endpoint: Calculation of the probability of disagreement (πD) between the e-tool and the physicians opinion regarding the appropriateness of the intervention. Secondary Objective: Evaluate the ability of the e-tool to classify interventions defined as appropriate and highly likely to succeed; (scores 7-9) at 3 different time points: trial, 6-month follow-up, and 12-month follow-up. The proportion of interventions that were successful at the trial implantation in different time points will be compared with the proportion of interventions identified as appropriate and highly likely to succeed by the e-tool. Study Period: 24 months. 12 months of enrollment + 12 months of follow-up. Subjects: Number of subjects to be included: at least 60 (total divided between the two centers) Participating Centers: - Pain Therapy Unit - ICSMaugeri, Pavia - Anesthesia and Pain Therapy SD - Azienda Ospedaliero Universitaria Pisana Pisa
