NCT ID: NCT03316066 Not yet recruiting - Clinical trials for Complex Regional Pain Syndromes

Comparison of Volumes of Local Anesthetics on the Efficiency and Safety of Stellate Ganglion Block for CRPS of the Arm

Start date: December 2017

NCT ID: NCT03309774 Recruiting - Clinical trials for Complex Regional Pain Syndrome Type I

Complex Regional Pain Syndrome in Children: Impact of Bergès Relaxation on the Autonomic Balance

Start date: October 18, 2017
Phase: N/A
Study type: Interventional

Complex regional pain syndrome (CRPS) is a disease provoking chronic pain in the limbs, following a trauma. Patient care is complicated by the variable clinical picture and response to treatment. The stress level of the organization, for chronic pain impacts the regulation of the autonomic balance. The study of time and frequency domain analysis of Heart Rate Variability (HRV) allows non-invasive and reproducible assessment of the autonomic balance.

NCT ID: NCT03291197 Not yet recruiting - Clinical trials for Complex Regional Pain Syndromes

Tolerability of Suprascapular and Median Nerve Blocks for the Treatment of Shoulder-hand Syndrome

Start date: October 15, 2017
Phase: Phase 4
Study type: Interventional

Shoulder-hand syndrome (SHS) in stroke patients is painful and lowers quality of life. Unfortunately, the cause of SHS is not known, diagnosing SHS can be difficult, and treating it can be hard. Recent research has shown that certain nerve blocks are good for treating shoulder pain for stroke patients, but no one has looked specifically as SHS. We think that specific nerve blocks involving a shoulder nerve (the suprascapular, or SSc nerve) and a hand nerve (the median nerve) will be helpful in reducing SHS pain. We will use ultrasound guidance to accurately inject these nerves. These injections have never been described for SHS patients however, so we want to make sure people with SHS can go through with the injections without too much pain or discomfort. That is, we want to test the tolerance of these injections for people with SHS. We are also hoping to better understand how consistent a set of diagnostic criteria, called the Budapest criteria, are at diagnosing SHS in order to be able to accurately diagnose this condition.

NCT ID: NCT03285113 Recruiting - Clinical trials for Failed Back Surgery Syndrome

A Study to Confirm the Safety of High Frequency DRG Stimulator in Patients With Chronic Lower Limb Pain

Start date: March 3, 2017
Phase: N/A
Study type: Interventional

This study is a prospective, single-arm, open label, single center pilot study to confirm the safety of a ultrahigh frequency DRG stimulator in patients with chronic lower limb pain. The actual trial length is 5 days. Pts will be given ultrahigh frequency pulse stimulation, and VAS will be obtained after 3-4 hours of each stimulation.

NCT ID: NCT03260361 Recruiting - Clinical trials for Algodystrophy of Hand

Hypnosis and MEOPA

Start date: September 6, 2017
Phase: N/A
Study type: Interventional

Relation between hypnosis and MEOPA on algodystrophy.

NCT ID: NCT03228160 Active, not recruiting - Clinical trials for Complex Regional Pain Syndrome

Light Irradiation and Outcome for Neuropathic Pain

Start date: October 1, 2016
Phase: N/A
Study type: Interventional

Background. Sympathetically maintained pain (SMP) can be effectively relieved by light irradiation to the area near stellate ganglion (SGI), which is applied as an alternative to sympathetic blockade. The clinical efficiency of SGI on heart rate variability (HRV) and its association with pain outcome need to be further identified. Objectives. This study is aimed to identify the effects of SGI on pain, HRV indices, quality of life, and function outcomes. Design. A prospective, double blind, randomized designed study Setting. An outpatient pain medicine clinic Subjects and Methods. A total of 44 patients will be enrolled and randomized to their allocations: the experimental group (EG, n=22) and control group (CG, n=22). All patients in EG will receive 12 sessions (twice a week) of standard SGI, while those in CG go through the same protocol except a shame irradiation is applied. Pain, HRV variables, quality of life, and function outcoms are measured before and after SGI in each session. All measures at the first-half and second-half courses are analyzed.

NCT ID: NCT03223623 Recruiting - Dystonia Clinical Trials

Pathophysiology of Dystonia and Complex Regional Pain Syndrome

Start date: December 20, 2017
Phase: N/A
Study type: Observational

Background: Little is known about the problems in brain function in focal hand dystonia (FHD) or complex regional pain syndrome (CRPS) dystonia. It is unclear why some CRPS patients develop dystonia but others do not. Researchers want to learn which area of the brain is involved in CRPS dystonia compared with FHD. Objectives: To understand why people with CRPS develop dystonia, and if these reasons are different in people with FHD. Eligibility: Adults ages 18 - 70 with CRPS dystonia OR with CRPS without dystonia OR with FHD and Healthy volunteers of similar age. Design: Participants will be screened with physical exam, neurological exam, and medical history. They may give a urine sample and will answer questions. Participants can have 4 - 5 outpatient visits or stay at the clinical center for approximately 5-6 days. Participants will have MRI scans. They will lie on a table that slides in and out of a scanner that takes pictures of their brain. They will do small tasks or be asked to imagine things during the scanning. Participants will have transcranial magnetic stimulation (TMS) sessions for a few hours, with breaks. A brief electrical current passing through a well insulated wire coil on the scalp creates a magnetic pulse. This affects brain activity. Participants may do small tasks during TMS. Participants will have the electrical activity of their muscles measured during TMS sessions. Small sticky pads will be attached to their hands and arms. Participants ability to feel 2 separate stimuli as different will be tested by using a weak electrical shock to their fingers. They will also be asked to feel small plastic domes with ridges, that may cause discomfort.

NCT ID: NCT03203772 Recruiting - Neuropathic Pain Clinical Trials

Immersive Virtual Reality for Neuropathic Pain

Start date: January 2016
Phase: N/A
Study type: Interventional

Investigating how neuropathic limb pain, including phantom limb pain or complex regional pain syndrome, is affected by virtual reality. While several studies have looked into virtual reality for treating this type of pain, few have used the latest immersive virtual reality hardware combined with motion control for an engaging virtual mirror therapy experience. The investigators are interested in studying the use of virtual reality as an alternative treatment option for these conditions.

NCT ID: NCT03174249 Completed - Clinical trials for Complex Regional Pain Syndromes

Exposure Therapy Combined With Cortical Interventions for CRPS-II

Start date: September 1, 2012
Phase: N/A
Study type: Interventional

Consecutive patients with long-standing complex regional pain syndrome II in a lower limb are treated with graded exposure therapy in vivo in combination with methods targeting cortical reorganisation.

NCT ID: NCT03137472 Recruiting - Clinical trials for Complex Regional Pain Syndromes

TMS for Complex Regional Pain Syndrome

Start date: April 24, 2017
Phase: N/A
Study type: Interventional

The aim of the current study is to assess the efficacy of TMS in the treatment of Complex Regional Pain Syndrome (CRPS). It is hypothesized that participants who receive TMS (Group 1) relative to sham treatment (Group 2) once daily for two days will demonstrate a greater improvement in CRPS-related pain and other associated symptomology (i.e., cognitive, emotional and physical) compared to baseline. Participants will be followed until they reach their baseline for two consecutive weeks to assess safety and duration of symptom alleviation.
