Study consists of a 15 subject pilot phase with Axoguard® Nerve Cap implants followed for 3 months and then a comparative study of 86 subjects randomized between the treatment groups followed for 12 months.

Clinical randomized study to compare the clinical effectiveness between two modalities of treatment of trigeminal neuralgia namely gamma knife radio surgery and microvascular decompression

Neuropathic pain is described as a "pain initiated or caused by a primary lesion or dysfunction in the nervous system". It is thus often a chronic affection, as a difficult-to-treat condition. As such, there is growing proportion of patients with inefficient pain relief. The prevalence of chronic neuropathic pain has been estimated from 6.9 to 10% in the general population and represents a heavy financial burden for the health care systems. Spinal Cord Stimulation (SCS) is a well-established therapy to alleviate severe intractable neuropathic pain (SCS is a reversible treatment option which leads to improve pain relief and quality of life Using conventional SCS, the prerequisite to target any pain relief is to obtain an appropriate coverage of the painful area with induced paresthesia. Despite its effectiveness, conventional SCS has some limitations (Selectivity, Energy consumption …) and in order to address these limitations and challenges, medical devices and neuromodulation industries have developed the Dorsal Root Ganglion (DRG) stimulation. DRG stimulation appears to be a promising technology that can be proposed to patients with chronic neuropathic pain for several reasons: DRG stimulation has shown promising results in pathologies generating focal pain with more selectively than SCS, lead localization appeared to be less discriminative than SCS. Consequently, DRG seems more stable and efficient to relief pain with lower energy consumption than SCS (therapy can be delivered with very low amplitude compared to SCS). Last but not least, Abbott technology has moved forward to Burst stimulation a couple of years ago and validated this new way of delivering electrical stimulation through several major publications. To our knowledge, applying new waveforms to DRG has not been yet validated. This will represent a fantastic opportunity to refine the design of the next generation of Internal Pulse Generators (IPGs). To date, the baseline study comparing DRG stimulation to SCS is the ACCURATE study. This is a high quality prospective, multicenter, randomized comparative trial conducted in 152 patients implanted with either SCS or DRG stimulation system. Although ACCURATE study is well designed, it has some limitations. To bridge this gap, the investigators propose to conduct a randomized controlled trial (RCT) with a crossover design, where SCS and DRG stimulation will be used within patient in three conditions: (i) SCS alone, (ii) DRG stimulation alone (DRGS), (iii) combination of SCS and DRGS (DUAL). Our goal will be to compare SCS vs DRGS vs DUAL therapies in order to establish the superiority of DRG stimulation over SCS in a crossover design, assess the added value of hybrid stimulation (DUAL) over the separate standalone stimulation types, compare the different cortical pathways involved in both techniques, by functional imaging, incl. MRI, analyze energy consumption by optimizing neural targeting. assess the added value of applying Burst on these different targets, after a 3-month follow-up and to reinforce the perception of neurostimulation techniques through the pain community, as the investigators will demonstrate their benefits on pain relief, functional capacity and quality of life, with objectives measures and a randomized design. This study represents a unique opportunity to boost the rationale of SCS/DRGS since each arm of treatment will be blinded for the patient and the implanter.

Trigeminal neuralgia (TN) was defined by The International Association for the Study of Pain (IASP) as severe, sudden, usually unilateral, stabbing, brief, recurrent attacks of pain in one or more distributional branches of the trigeminal nerve. The purpose of the current study will to investigate the effect of Low level laser therapy versus electromagnetic therapy on diabetic trigeminal neuralgia pain intensity and amplitude of the compound muscle action potential of the masseter and temporalis muscles in diabetic TN patients.

Randomized controlled trial to assess the effectiveness and patient perception of the benefit of the Sana Pain Reliever in individuals with chronic neuropathic pain.The study is fully remote with four study visits taking place over teleconferencing and the study devices mailed to the participants to use at home for 8-14 weeks.

Distal sensory peripheral neuropathy (DSP) is a chronic, debilitating painful condition affecting quality of life in persons living with Type 2 diabetes. Treatments prescribed to manage DSP pain, such as nonnarcotic and narcotic analgesics, antidepressants and anticonvulsants, are largely ineffective. This is a preliminary study at assessing the feasibility, efficiency and preliminary efficacy of a novel non-pharmacologic pain management approach, moxibustion, to reduce DSP pain and improve quality of life.

The current study investigated the efficacy of pulsed radiofrequency in pain reduction in TN patients and compared the efficacy and the impact on the quality of life of the standard technique with a prolonged duration technique and a higher voltage one. Entire enrolled patients were diagnosed as classic TN according to the international headache society classification (IHS, 2013) and underwent brain MRI and MRA to exclude secondary causes. Patients were randomly divided into three groups, Group A patients underwent PRF using the standard settings, group B patients underwent PRF with prolonged duration and Group C patients underwent PRF with higher voltage. VAS and pain amplitude reduction were recorded before the intervention and 1 hour, 1 day, 1week, 1 month, 6 months and 1year after it. Quality of life was assessed before and 1 year after the intervention.

As lidocaine and ketamine provide analgesia by acting on different molecular pathways, administering them together may produce synergistic effects, which can allow for using a lower dose of each medication and thereby reducing the corresponding side effects. To the investigator's knowledge, despite the common practice of multimodal analgesia, lidocaine-ketamine infusions have never been studied prospectively in an out of hospital setting to treat neuropathic pain. The aim of the present study is to evaluate the effectiveness of the current routine practice of lidocaine-ketamine infusions conducted at Allevio Pain Management Clinic, a large outpatient community based chronic pain management facility. Lidocaine-ketamine infusions are prescribed to patients that have pain that is considered to be neuropathic for which standard anti-neuropathic medications have been ineffective or poorly tolerated by patients. A prospective longitudinal study.

In this randomized controlled study, investigators planned to investigate the efficacy of oral occlusive splint and therapeutic home exercises in increasing the quality of life and reducing somatic and neuropathic pain in patients with temporomandibular joint dysfunction, determine their effects on other clinical data, and report long-term outcomes

In summary, this small-scale study is designed to demonstrate that the NFX88 is safe and well tolerated, as well as preliminary evidence of improvement in the score of VAS, PD-Q, and PGIC scales.
