Active clinical trials for "Somatoform Disorders"

Post-Mastectomy Pain Syndrome (PMPS) is a chronic pain that persists for more than three months after a surgical breast procedure. It has 11-70% incidence in patients that underwent a breast surgery. It consists of mixed pain, frequently associated with myofascial pain, an specific type of muscular pain. Trigger point injections (TPI) are classically used for the treatment of myofascial pain in other painful conditions. However, there are no controlled trials assessing the efficacy of TPI in the treatment of PMPS. The intervention objective is to assess the efficacy of TPI in patients with PMPS, when associated with a comprehensive rehabilitation program and pain management.

This is a Randomized Controlled Trial (RCT) regarding conservative treatment of Patellofemoral Pain Syndrome (PFPS). Patellofemoral Pain Syndrome (PFPS) is a very common cause of knee pain in young active adults with a high rate of recurrent and/or chronic occurrence. PFPS is notoriously difficult to treat and has been referred to as "one of the most vexatious clinical challenges in rehabilitative medicine". Its etiology is unclear but is commonly thought to be related to pathomechanics in the patellofemoral joint (PFJ). There are many factors that can influence PFJ mechanics. Among these, quadriceps strength and timing has been shown to be important. As such, treatment of PFPS has traditionally been based on correction of pathomechanics through influencing quadriceps strength and timing. However, a growing body of evidence is revealing the importance of strength and control of hip abduction and external rotation in PFPS. Hip strength in ab/adduction and rotation is thought to influence femoral positioning in the patellofemoral joint, thereby affecting PFJ mechanics. Several cohort and smaller RCT studies within the last 7 years have shown that additional exercises for hip strength and control give an improved effect in pain and function compared with quadriceps based training alone. A smaller RCT from 2012 compared isolated hip strengthening exercises to a control group and found surprisingly good results on pain in function in the hip strengthening group. The investigators plan a RCT in which isolated hip strengthening will be compared to traditional quadriceps training and a control group which will receive no structured training. Primary outcomes will be pain and function. This high-quality study will include 40-50 patients in each group, making it one of the largest of its kind on conservative treatment for PFPS. In contrast to the vast majority of studies of this type, this study will also include men, which will potentially help to fill a significant gap in the literature on this subject. The investigators study will therefore be an important contribution to elucidating the etiology of PFPS and improving treatment options for both men and women in the future. As well, the role of psychometric parameters will be examined and a standardized clinical test for hip abduction endurance will be developed. Follow-up at 3 months and 12 months is completed and published. A 5-year follow-up of the same patients is underway.

Vitamin C with its antioxidant role has many indications. The objective of this study is to demonstrate that taking vitamin C as a preventive significantly reduces the occurrence of complex regional pain syndrome (CRPS) type 1 in the aftermath of a scheduled surgery of the upper limb.

This work will answer two critical questions: 1) Does intensive interdisciplinary pain treatment (IIPT) involving aerobic exercise help normalize pain processing in youth with chronic pain syndromes and 2) Are aerobic fitness levels and the ability to modulate pain inter-related? Currently, medications are ineffective for improving pain and disability in youth with chronic pain syndromes and identifying non-pharmacologic treatments, such as IIPT, that help strengthen the nervous system's ability to modulate or turn pain signals down will improve outcomes and quality of life for youth suffering from chronic pain. This study will help determine whether exercise based IIPT leads to physiologic improvements in how pain is processed, specifically if youth with chronic pain can better turn pain down during the offset analgesia test after an exercise based IIPT treatment, and also help elucidate the link between a child's aerobic fitness and their ability to modulate pain.

Purposes of the study To investigate the effect of adding Short foot exercise on patellofemoral pain syndrome on knee Pain, Function, Balance and abductors, quadriceps Muscle strength.

The aim of the study is to investigate the efficacy and safety of LiST retreatment for CP/CPPS patients.A total of 50 patients with CP/CPPS diagnosis who were previously treated with 6 sessions of LiST will participate in this study.The primary study parameter is the CP/CPPS-related pain complaints and it will be assessed by the NIH-CPSI

Over the last years a rising medical need for treatment of chronic pain was identified. Based on previous findings indicating the pain modulating effects of cannabinoids in chronic pain disorders, this clinical trial investigates the efficacy and tolerability of the THC-focused nano endocannabinoid system modulator AP707 in patients with chronic back pain disorders. Patients receive AP707 or placebo over the course of 14 weeks as an add-on to the standard of care. Changes in pain intensity, quality of life and sleep and others measures are monitored through different scales to assess the efficacy of AP707 in patients with chronic back pain.

Over the last years a rising medical need for treatment of chronic pain was identified. Based on previous findings indicating the pain modulating effects of cannabinoids in chronic pain disorders, this clinical trial investigates the long term efficacy and tolerability of the THC-focused nano endocannabinoid system modulator AP707 in patients with chronic pain disorders due to traumatic or post-operative peripheral neuropathy. Patients receive AP707 or placebo over the course of 14 weeks as an add-on to the standard of care. Changes in pain intensity, quality of life and sleep and others measures are monitored through different scales to assess the efficacy of AP707 in patients with chronic pain due to traumatic or post-operative peripheral neuropathy.

This study relies on the use of a smartphone application (SOMA) that the investigators developed for tracking daily mood, pain, and activity status in acute pain, chronic pain, and healthy controls over four months.The primary goal of the study is to use fluctuations in daily self-reported symptoms to identify computational predictors of acute-chronic pain transition, pain recovery, and/or chronic pain maintenance or flareups. The general study will include anyone with current acute or chronic pain, while a smaller sub-study will use a subset of patients from the chronic pain group who have been diagnosed with chronic low back pain, failed back surgery syndrome, or fibromyalgia. These sub-study participants will first take part in one in-person EEG testing session while completing simple interoception and reinforcement learning tasks and then begin daily use of the SOMA app. Electrophysiologic and behavioral data from the EEG testing session will be used to determine predictors of treatment response in the sub-study.

The goal of this observational study is to compare thermal camera Forward Looking InfraRed (FLIR) images before and after spinal cord stimulation to evaluate the difference in sympathetic activity of the affected limb in patients with complex regional pain syndrome (CRPS). The main questions it aims to answer are: Question 1: Can Infrared (FLIR) imaging be used to monitor the sympatholytic activity caused by Spinal Cord Stimulation (SCS) in patients with CRPS? Question 2: Is there any correlation between the quantification of sympatholytic activity produced by Spinal Cord Stimulation (SCS) and measured by FLIR imaging with the outcome measures in patients with CRPS? Outcome measures include pain (NRS), CRPS Severity Score (CSS), Quality of Life (SF-36), and neuropathic pain score (painDETECT). Participants will have an image of their feet taken perpendicularly with a 1-inch space from all four sides using a FLIR T420 or T62101 camera with 320*240 resolution. Participants will also complete questionnaires about the average pain, CRPS severity, quality of life, and neuropathic pain.
