Filter by:Complex Regional Pain Syndrome (CRPS) is a rare and often debilitating chronic pain condition whereby individuals may experience extreme sensitivity, discoloration, and swelling of the affected area -- along with numerous other painful symptoms. There are currently a limited number of treatment options available to those suffering with the condition, with various treatments including nerve blocks, neuropathic medications, and desensitization physical therapy modules. There is budding interesting in the role naltrexone, an opiate antagonist, may play in the pain management of CRPS when prescribed in very low doses. This study aims to collect preliminary data on pain scores, symptom severity, and side-effects in patients with Complex Regional Pain Syndrome randomized to receive low dose naltrexone or placebo capsules. Enrollment of 40 patients total will occur over two years from study start to study end. Each patient will be randomized to receive placebo capsules or active low dose naltrexone capsules, with both the patient and treating clinician blind to the randomization. Each patient will be actively enrolled in the study for six months and will take the medication daily at the instructed dose for the respective duration of time. Following the initial visit and study enrollment, the investigators are asking each patient to return for three (3) in-person follow-up office visits. These office visits will occur 1 month after the patient starts the medication, 3 months afterwards, and 6 months afterwards. The final 6-month office visit will mark the conclusion of the patient's active participation in the study.
Patients will be divided into 2 groups according to the random numbers table, and both groups will receive a conventional physical therapy and rehabilitation program and nutritional support. Afterwards, edema-reducing kinesiotaping will be applied to one group. The applied kinesio tape will remain on the patient for 5 days and will be taped again after 2 days without tape. In this way, taping will be done 3 times in total, once a week for 3 weeks. During this period, patients will continue their routine physical therapy program and measurements will be taken by the same researcher in the 1st week of treatment and 3 weeks later.
The aim is to evaluate the efficacy of Mirror Therapy on pain reduction and hand function in subjects with unilateral upper extremity Complex Regional Pain Syndrome Type I.
Background: There is low quality evidence supporting the use of rehabilitation in Complex Regional Pain Syndrome (CRPS), despite it is the first line approach in the Guidelines . Graded Motor Imagery (GMI) may be useful to improve pain and function at mid term (6 months). Graded Pain Exposure Approaches (GPE) seem to improve pain but not function at mid term. In other type of chronic pain conditions GPE offers better outcomes than "pain contingent" (exercises avoiding pain) approaches at short term (3 months) and similar at mid term. Following the recommendations of Authors, we will evaluate the efficacy and safety of a combined therapy of GMI and GPE in people with CRPS type 1. Objective: To evaluate the feasibility of a combined therapy of GPE and GMI in front of only GMI in people with CRPS-1 and the clinical impact on the primary outcome (Severity of the disease) of the intervention. Design: Feasibility Randomized controlled Trial, single blind of evaluator, 2 parallel arms. Measurement pre-intervention, post-intervention , 1 and 3 months follow-up. Population: People 18 years old or above with CRPS type 1 diagnosed by Budapest criteria and (1) without any psychological or psychiatric disease, (2) nor any neurosensorial issue that could compromise the realization of the therapy proposed (3) neither any major surgery intervention related to CRPS (e.g neurostimulation or sympathectomy) (4) nor minor intervention on the last 3 months (e.g. nerve blocks). Outcomes: Primary outcomes: Complex Regional Pain Syndrome Severity Scale (severity of the disease) and Safety Outcomes ( oedema, pain, temperature, Range of Motion). Secondary outcomes: 5Q-5D-5L (quality of life), SF-MPQ (Quality, Intensity and location of pain), PPT (pain pressure threshold), CPM ( pain inhibition pathways), FAAM or Quick Dash (function), PCS (catastrophism), Self efficacy in chronic pain questionnaire (self-efficacy), Dynamometry (Hand Grip strength),
In this study, it is the procedure of spinal cord stimulation in Burst mode, its results and the experience of the patients that are evaluated.
Subjects with complex regional pain syndrome (CRPS) Type 1 will be randomized to receive repeated transcranial magnetic stimulation (rTMS) followed by rehabilitation or sham rTMS followed by rehabilitation. Treatment will last for 4 weeks, with the first week including 4 rTMS treatments and 2 rehabilitation treatments. Subsequent weeks will include 2 rTMS treatments followed by 2 rehabilitation treatments. Outcome measures will include pain ratings, PROMIS questionnaires, global rating of change, and grip strength or 1 repetition maximum leg press.
The purpose of this study is to investigate, for the first time, whether gut bacteria composition and function of patients with CRPS differ from those of healthy adults. Samples of stool, urine and blood will be collected from patients with CRPS and from healthy adults. The type and function of bacteria of CRPS patients will be analyzed and compared to those of healthy adults to test if potential differences could explain the mechanism/s involved with the development of 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.
Spinal cord stimulation (SCS) delivered at 10kHz frequency (HF10 Therapy) has demonstrated superiority to traditional SCS for leg and back pain. Intermittent dosing (ID) refers to the cycling of stimulation, in which there is a designated time period of stimulation being active (ON) and inactive (OFF). Previous studies have demonstrated the safe and effective use of intermittent dosing. However, there still remains a paucity of clinical data on the use of intermittent dosing and which doses (i.e. on/off cycle time periods) are most effective. Furthermore, no previous studies have utilized HF10 therapy when evaluating intermittent dosing. Patients with chronic back and/or leg pain who have undergone permanent spinal cord stimulator implantation delivered by the Nevro Omnia Neurostimulation System and who are reporting decreased efficacy of continuous HF10 therapy will be randomized into one of two treatments: 1) Intermittent Dosing therapy at 30 seconds ON, 90 seconds OFF 2)Intermittent Dosing therapy at 30 seconds ON, 360 seconds OFF. After randomization, each consented subject will present to clinic at which time will first be seen by a team of investigators, sub-investigators, and/or study staff. After evaluation and collection of baseline data, a clinical specialist for the Nevro Omnia Neurostimulation system will program the subject's SCS system according to the treatment group to which they have been randomized, under direct physician supervision Patient's will be seen and evaluated prior to randomization, and thereafter at 2, 4 and 6 weeks. At the 6-week time period, patients will be crossed over to the other study arm and thereafter evaluated at 2, 4 and 6 weeks. As our primary endpoint, we hypothesize that ID HF10 therapy will provide non-inferior pain relief as measured by VAS scores when compared to continuous HF10 therapy. Other endpoints include: charging frequency, EQ-5D scores of wellbeing; PROMIS score for physical function, pain interference, sleep disturbance, and emotional distress; chronic pain acceptance questionnaire 8 (CPAQ-8), patient satisfaction scores, and patient global impression of change
Complex regional pain syndrome (CRPS) is a post-traumatic chronic pain condition characterized by pain and other symptoms typically affecting a distal limb. Relatively little is known about the prognosis of the course of CRPS .Currently there is no specific test to diagnose CRPS. The primary objective of the study is to investigate prospectively the evolution of CRPS and the impact of the psychosocial factors on health status, recovery, quality of life, and working status of CRPS patients. The secondary objective of the study is to measure blood parameters in CRPS patients to investigate their evolution during the course of CRPS, and maybe to identify distinctive biomarkers associate with CRPS and that could be potential candidate for diagnosis.
