Active clinical trials for "Chronic Pain"

Methadone is a synthetic mu opioid agonist that has been proved as clinically effective in pain management. However, methadone usage for pain control in Thailand has been limited because physicians are not familiar with its dosing and concern about the risk of drug accumulation and cardiac arrhythmia. Therefore, this prospective study was conducted to evaluate the efficacy and safety of a methadone protocol in Thai patients with severe chronic noncancer and cancer pain.

Chronic low back pain, with or without lower extremity pain, which arises from various structures of the spine constitutes a majority of pain complaints. The sacroiliac joint (SIJ) has been implicated as the primary source of pain in 10% to 27% of patients with mechanical low back pain below L5 vertebra. The common causes of SIJ pain include a trauma like direct fall on the buttocks, a rear-end or broad-side type motor vehicle accident, and an unanticipated step into a hole or from a miscalculated height, fusion surgery, anterior dislocation, inflammatory and degenerative sacroiliac joint disease and idiopathic. The treatment of SIJ pain remains a therapeutic challenge. Besides physiotherapy and systemic therapies including non-steroidal anti-inflammatory drugs (NSAIDs) and biologic agents, intra-articular and peri articular injections of SIJ, radiofrequency neurotomy and surgical fusion are often performed for pain relief. However, the success of these interventions has been determined according to the therapeutic efficacy and correct placement of the drug. The image guidance of SIJ injections seems to be important due to the complex anatomy of the joint causing a low accuracy when performed according to clinical judgement only. The feasibility of ultrasound (USG) guided injection of SIJ has recently been demonstrated resulting in very high success rates up to 90%. Various agents being used in SIJ injections include local anaesthetics, corticosteroid, botulinum toxin-A, 12.5% dextrose, phenol-glycerine-glucose (P2G) and sodium morrhuate (cod liver oil extract). SIJ steroid injection is commonly used technique and has been found to be effective to treat SIJ pain. However, the main drawback is short term effect. Borowsky et al reported improvement in visual analog score (VAS) of 14.1% and reduction of VAS ≥ 50% in only 12.50% patients at 3 months after intra-articular steroid (2 mL 0.5% bupivacaine plus 40 mg methylprednisolone) SIJ injection. Treatment modalities being currently used do not, in general, address the disease process itself, there is clearly a need to investigate treatments that are more widely applicable for symptom management and which may also directly address the disease process itself. Current research efforts aim at modifying the rate of healing of joint by using biological healing factors which are various growth factors (transforming growth factor, vascular endothelial growth factor, fibroblast growth factor, epidermal growth factor, platelet derived growth factor etc.) found abundantly in the human blood especially in platelets. The platelet rich plasma (PRP) is an ideal autologous biological blood-derived product, which can be exogenously applied to various tissues where it releases high concentrations of platelet derived growth factors that enhance the body's natural healing response. In addition PRP possesses antimicrobial properties that may contribute to the prevention of infections. PRP is now being widely tested in different fields of medicine for its possibilities in aiding the regeneration of tissue with low healing potential. Local injection of PRP is a new modality which has been effectively used for the treatment of Achilles tendon injury in athletes, chronic epicondylar tendinopathy, chronic patellar tendinosis, rotator cuff tear, anterior cruciate ligament injury, gonoarthrosis and plantar fasciitis. The intra-articular injection of PRP into knee joint has been found to reduce the incidence of local inflammatory changes in early knee osteoarthritis. Recently, PRP has been used for low back pain caused by SIJ laxity showing significant improvement in pain scores. However, there is no study at present comparing the efficacy of intra-articular injection of PRP with corticosteroids for the treatment of chronic SIJ pain. Considering the vast potential of PRP and its safety, this study aimed at studying the efficacy of ultrasound guided intra-articular SIJ injection of leukocyte free PRP for chronic low back pain due to SIJ pathology. In the current study, we tested the hypothesis that the SIJ injection of leukocyte-free PRP may be more effective for the treatment of sacroiliac joint pain as compared with steroid injection.

The purpose of this study is to determine whether yoga is effective for the treatment of chronic pain in Gulf War Illness.

Will a primary care-based behavioral intervention for patient activation and engagement and self-management, for patients with chronic pain who are taking opioid pain medication, result in better patient outcomes than Usual Care?

Fibromyalgia (FM) is a chronic pain condition affecting several millions of Canadians. Although the etiology and pathophysiology are poorly understood, there is a well-recognized association between muscular pain in fibromyalgia and muscular hypoperfusion, hypoxia, abnormal muscle metabolism and oxidative stress. Currently there is no cure for FM. Pharmacological and non-pharmacological strategies are directed to control symptoms such as pain, fatigue, non-restorative sleep and depression. Hyperbaric oxygen therapy (HBOT) is an intermittent inhalation of 100% oxygen in a hyperbaric chamber at a pressure higher than 1 absolute atmosphere. Physiological effect of HBOT is based on a dramatic increase in the amount of dissolved oxygen carried by the blood which enables oxygenation of ischemic areas with compromised circulation. It also activates oxidant-antioxidant system, stimulates angio- and neurogenesis, modulates inflammatory response, induces brain neuroplasticity and possesses analgesic effect. While some interventions offer benefit for some patients, additional treatment alternatives are needed for patients with FM in whom currently available options are either ineffective or poorly tolerated. Given its physiological effect, HBOT could be considered as a potential therapy for treatment of underlying muscular hypoxia, optimizing oxidant- antioxidant system and controlling FM symptoms. The results from this study could therefore provide new information supporting the basic science underling the pathophysiology of this disease and stimulate novel therapies for patients suffering with FM.

Chronic pain is a major public health problem that places many burdens on individuals, including impairment of physical and psychological functioning, lost productivity, and side effects of medications used to treat pain. There is also substantial evidence that minority populations differ both in prevalence and outcomes of chronic pain; access to care is a key component in these differences. Strong evidence now supports the use of acupuncture in the treatment of chronic pain conditions, including when provided in the primary care setting to participants from ethnically diverse, medically underserved populations. Acupuncture is slowly being integrated into pain management in many conventional health care settings, but cost and reimbursement for this service remain obstacles to offering acupuncture, especially in primary care and safety net settings. Because group acupuncture can be offered at much lower cost, demonstrating that individual and group delivery are equally effective could reduce barriers to use of this effective pain management approach. The primary aim of this study will be to evaluate whether acupuncture delivered in the group setting for participants with chronic pain is equal to acupuncture delivered in the individual setting. A secondary objective will be to use qualitative analysis to understand and describe the participants' experience of both acupuncture approaches, and to utilize this data to inform intervention delivery and dissemination, to better incorporate the participants' perspective.

There are an estimated 100 million Americans with chronic pain. The enormity of the problem at the societal level is staggering, not simply in terms of its sheer prevalence but also the societal costs, including health care expenditures, disability compensation, lost productivity, and lost employment potential. The pharmacological focus in treatment tends to give patients with chronic pain a negative stereotype as many are viewed as drug seeking, or worse, they are perceived to have an imaginary illness. It is argued that these stigmas not only negatively affect the patients' healthcare experience, but also perpetuate maladaptive coping. In addition, it is suggested that reliance on pharmacological approaches have contributed to the rate of overdoses from prescribed opioids. In order to address this burden facing society, patients need opportunities to foster a sense of self-efficacy to manage their pain, as well as improve their healthcare experience by allowing them to dialogue with their clinician openly and freely about their chronic pain, and coping strategies. This study is designed to explore the impact of an intervention using photo-elicitation (based on Photovoice) and online group support (via Facebook) on participants' overall experience of chronic pain and patient-identified areas of function. Photovoice participants will utilize cameras that enable them to record issues related to their experiences, and subsequently display them. This method serves as an empowering tool to connect participants to key stakeholders in the community, facilitates change and opportunities that otherwise would not be available to marginalized groups.

The primary purpose is to examine the impact that physical therapy (PT) interventions, including manipulations, have on physical activity levels outside of the clinical environment in persons with low back pain (LBP) as measured both objectively with an accelerometer and subjectively with questionnaires. The secondary purpose is to determine if a relationship exists between objective physical activity, self-perceived disability pain catastrophizing thoughts, BMI, age, six-minute walk distance, lower extremity muscle endurance. The tertiary purpose is to assess the predictive value that a standing manual lumbar unloading technique has for relief of pain following manipulation
