Active clinical trials for "Chronic Pain"

Intercostobrachial nerve (ICBN) is a cutaneous nerve that provides sensation to the lateral chest, upper medial arm and axilla. It arises from the second intercostal nerve and leave intercostal space at the level of midaxillary line. It then pierces the serratus anterior muscle and enters axilla. Intercostobrachial nerve is encountered during axillary lymph node dissection (ALND) while mobilizing axillary contents laterally off the chest wall and tends to tether axillary contents to the lateral chest wall. Many surgeons routinely sacrifice it as doing so makes mobilization easier and allow exposure of long thoracic neve. Currently there is no consensus on the usefulness of preserving intercostobrachial nerve. According to a 2020 systemic review and meta-analysis, prevalence of CPSP/ PPSP following breast cancer surgery ranged from 2% to 78% and pooled prevalence was found to be 35%. Higher prevalence was associated with ALND. Several risk factors have been identified which contribute to the development of PPSP. These include; Preexisting pain, preoperative opioid exposure, genetics, psychological factors such as anxiety, depression or catastrophizing, intensity of acute postoperative pain and nerve injury during surgery. As a result of nerve injury, damaged and non-damaged nerve fibers start generating action potential spontaneously. These are considered ectopic inputs as they do not arise from peripheral terminals. These inputs lead to the development of central sensitization, which is a state of exaggerated functional response of neurons involved in the pain pathway. This increased sensitization results due to increased membrane excitability, enhanced synaptic efficacy and decreased inhibition. The aim of the present trial is to investigate the effect of ICBN preservation on chronic/ persistent post surgical pain (CPSP/ PPSP). This will be achieved through a randomized control trial with CPSP/ PPSP as a primary outcome measure. Secondary outcome measures will include Health Related Quality of Life (HRQoL), operating time, lymph node yield, functional status of ipsilateral shoulder, post-operative complications and post-operative use of opioid analgesics.

Clinical symptoms that are often found to be comorbid with pediatric chronic pain include anxiety, depression as well as increased stress, obesity, and decreased physical conditioning. Integrative therapies have been increasingly offered at children's hospitals as part of an integrated approach to treatment. Limited research exits on the efficacy of mind-body practices (e.g., yoga) utilized in conjunction with evidenced-based non-pharmacological treatments like cognitive behavioral therapy (CBT) to treat pediatric pain. Hence, this 7-week interventional pilot study was conducted to evaluate the impact of combining yoga and CBT for both pediatric patients with chronic pain and their caregivers.

The aim of this study is to examine the effect of transcutaneous pulsed radiofrequency current in the treatment of carpal tunnel syndrome.

The purpose of this study is to determine whether group based Acceptance and Commitment Therapy (ACT) at a university hospital clinic is superior to treatment in a primary care setting among patients with chronic pain. Hypothesis: i) A group based ACT treatment leads to less pain and greater Health Related Quality of Life (HRQOL) in patients with chronic pain than treatment in a primary care setting. ii) The improvement in pain and HRQOL is mediated through an increased degree of pain willingness and involvement in activities. iii) Improvement of pain and HRQOL after the two treatments is associated with demographic, psychosocial and somatic characteristics.

During the typical SCS trial the leads remain outside of the skin and can be prone to migration. The leads are typically secured in place with suture, tape, or a combination of both. This study will evaluate the amount of movement based on the method of being secured at the time of placement

For patients with chronic pain, how does a 10 minute guided body scan meditation affect pressure pain threshold and extent of pain on a body diagram?

The purpose of this study is to compare two types of acupuncture with usual care on treating chronic pain. This study has three groups. Two groups will received acupuncture. One group will receive usual standard of care for 12 weeks and then will receive acupuncture. Acupuncture is an ancient Chinese technique of using very thin needles inserted in the skin to treat different symptoms and illness, and to promote healing. Each group will undergo a different method of needle administration.

Quantitative Sensory Testing (QST) is a novel investigative technique used in other pain conditions to evaluate patterns of chronic pain, and in this study will be used to elucidate pain patterns in patients with Chronic Pancreatitis (CP). QST uses a specific series of standardized stimulations to map the pain system. QST has the potential to change and improve the treatment paradigm for patients with CP and may eventually be able to predict response to invasive CP therapies.

The purpose of the chronic pain master protocol is to compare independent pain interventions and establish an overarching structure for the disease-state addenda (DSA) and intervention-specific appendices (ISAs). The ISAs may start independently of other ISAs as interventions become available for clinical testing.

ACNES is a neuropathic pain condition of the abdominal wall. It is a clinical diagnosis based on patient's history and physical examination. No diagnostic test is available to confirm the diagnosis. This pilot study will determine if skin biopsies can be used as diagnostic test. Two 3mm biopsies will be taken and used to count the small nerve fibres in the skin. The number of small nerve fibres of the painful skin will be compared to non-painful skin. Skin biopsy and small fibre nerve count is already used as diagnostic test in patients with small-fibre neuropathy. The investigators hypothesize that patients with ACNES will have a reduced number of small nerve fibres in the affected skin, compared to the non-affected skin.
