Filter by:Intravenous administration of esketamine is an effective recognized therapeutic option in refractory pain in CRPS, which sometimes in at least a part of the patients has a prolonged therapeutic effect. Unfortunately, CRPS literature contains a wide range of ketamine dosing regimens with the result that clinical protocols on dosage and administration are very heterogeneous. The current esketamine regimen in Erasmus MC consists of a 6-day hospital admission for continuous administration. In the Netherlands, both inpatient and outpatient esketamine treatments are offered. Inpatient and outpatient ketamine treatments have never been compared in randomized controlled trials and it is therefore unknown whether these two dosing regimens are equally effective. The primary objective is to demonstrate non-inferiority of experimental esketamine administration of 6x 1 day per 2 weeks (in total 3 months) as compared with standard esketamine administration of 1x 6 consecutive days. The end of study is at 6 months after the start of the study/treatment.
This study will investigate the feasibility of using repetitive transcranial magnetic stimulation (rTMS) and a sensorimotor training task to treat symptoms of pain in patients with complex regional pain syndrome (CRPS). rTMS is a non-invasive technique that involves delivering magnetic pulses in rapid succession over the area of the brain that controls movement. The sensorimotor training task involves non-invasive nerve stimulation used to cue a participant to complete motor actions. The purpose of this study is to determine whether recruitment is feasible in this patient population and patients maintain adherence to the intervention. In addition, the investigators want to determine whether rTMS combined with sensorimotor training is an effective intervention to alleviate symptoms of pain in patients with CRPS.
Virtual reality creates interactive, multimodal sensory stimuli that have demonstrated considerable success in reducing pain. Much research so far has focused on VR's ability to shift patients' attention away from pain; however, these methods provide only transient relief through means of distraction and therefore do not offer long-term analgesic remediation. An alternative and promising approach is to utilize VR as an embodied simulation technique, where virtual body illusions are employed as tools to improve body perception and produce potentially more enduring analgesia. Disturbances in body perception (i.e., alterations in the way the body is perceived) are increasingly acknowledged as a pertinent feature of chronic pain, and include aberrations in perceived shape, size, or color that differ from objective assessment. The degree of body perception distortion positively correlates with pain, and prior interventions have evinced that treatments aimed at reducing body perception distortions correspondingly ameliorate pain. Several recent experimental research studies have demonstrated the analgesic efficacy of body illusions in a range of pain conditions. Immersive VR multisensory feedback training signifies a promising new avenue for the potential treatment of chronic pain by supporting the design of targeted virtual environments to alter (distorted) body perceptions. Various illusions have been described to alter pain perception; however, they. Have not been directly compared to each other. The multimodal stimulus control of VR enables physical-to-virtual body transfer illusions, resulting in the feeling that the virtual body is one's own. These virtual body illusions can modulate body perception with ease and could therefore be used to alter the perceived properties of pain, consequently utilizing a virtual avatar to specifically shape interactive processing between central and peripheral mechanisms.
Shoulder-hand syndrome is a common complication following stroke, constituting of excessive pain, swelling, heat, limited range of motion, and trophic change of the affected limbs. It not only has an extensive negative impact on both physical and psychological aspects of a stroke patient's well-being, but also impose burden on the health care system and the patient's family. Despite its relatively high incidence, there is neither well-established treatment protocol, nor high quality evidence for a single effective treatment. The objective of the present study is to investigate the efficacy, including pain, spasticity, and subluxation reduction, muscle strengthening, and shoulder range of motion improvement, of high-intensity peripheral magnetic stimulation generated by the super-inductive system to treat patients with post-stroke shoulder-hand syndrome.
This study aims to assess the longus colli muscle thickness by ultrasonography in order to guide stellate ganglion blocks
Complex Regional Pain Syndrome (CRPS) / Complex Regional Pain Syndrome (CRPS) is a chronic neurological disorder that affects the extremities and is characterized by disabling pain, swelling, vasomotor instability, sudomotor abnormality, and impaired motor function; the duration and clinical magnitude is greater than expected, being divided into three stages of progression over time: Stage I: acute (0-3 months); Stage II: dystrophic (3-9 months); Stage 3: atrophic (9-18 months). The purpose of this study is to investigate the effect on complex pain syndrome using a conventional care protocol plus the application of non-invasive neuromodulation during compared to the effect of the same protocol plus placebo.
The purpose of this study is to demonstrate safety and efficacy of a new spinal cord stimulation paddle electrode which is able to target the dorsal horns, dorsal nerve roots, and dorsal columns. The research electrode ("Study Electrode") is designed to answer basic physiological clinical research questions. It may inform future device therapy development, but the Study Electrode is not a product that will be marketed or sold. The Investigators believe the protocol is a Non-Significant Risk study answering basic physiological research questions, which may be performed under hospital IRB approval.
The aim is to study another alternative for the treatment of pain in people with CRPS. Indeed, the TRAB / Medullary occupational therapy department of the CMRRF in Kerpape used compression garments to reduce edema when it was present.In the case of CRPS of the upper limbs, gloves or compression sleeves are used to decrease the edema which is sometimes associated, although they are not supported for this indication. In this context, our clinical experience leads us to believe that there would also be some efficacy in neuropathic pain, this improvement being regularly described by patients.This study is expected to show a notable reduction in neuropathic pain thanks to the wearing of a compression garment.
This study seeks to evaluate the use of intermittent dosing as an alternative paradigm for patients with DRG stimulation in place for at least 1 year and minimum 50% pain relief in the targeted area. Patients will be prospectively randomized to one of two stimulation paradigms both of which involve intermittent dosing at 30 seconds ON and 90 seconds OFF. Group 1 will have their frequency set at 20 Hz with amplitude levels adjusted in order to remain in the therapeutic window (subthreshold stimulation). Group 2 will have their frequency set at 5 Hz with amplitude levels adjusted in order to remain in the therapeutic window (subthreshold stimulation) This study will be performed in a crossover fashion, meaning patients will be changed to the alternate dosing regimen at the 13-week time period. Patients will be seen and evaluated prior to randomization and reprogramming, and thereafter evaluated at 4, 8, and 12-weeks. At the 12-week time period, patients will begin a 1-week washout period of continuous stimulation. At the 13-week time period, patients will be evaluated, crossed over to the other study arm and thereafter evaluated at 17, 21, and 25-weeks.
The purpose of this study is to investigate the effect of ultrasound-guided thoracic paravertebral block (TPVB) when performing sympathetic block for upper limb pain control.
