Active clinical trials for "Chronic Pain"

Pain is an unpleasant sensation common to all those who undergo surgery. Several studies indicate that 40-60% of patients experience the post-operative experience and can be caused by both internal and external stimuli. The most patients define the post-operative experience as a very painful condition that interferes with normal daily activities. Chronic post mastectomy pain is a condition characterized by pain in the anterior chest, armpit, and/or upper arm, usually ipsilateral to surgery, which begins after mastectomy or quadrantectomy and persists for longer. three months after surgery. It can become chronic in a broad spectrum of conditions. In fact, it is estimated that between 10 and 50% of elective interventions can generate persistent post-surgical pain. Aim of this prospective observational study is to evaluate the effects of motor and/or sports activity on the intensity and interference of chronic pain in quality of life of women underwent mastectomy.

The beliefs held by students lead to behaviours in response to their pain which can be both helpful or a hindrance to how they manage their pain. The one-day education event aims to educate the cohort on the contemporary scientific understanding of persistent pain. It is hoped this event will result in an improvement in the alignment of beliefs and behaviours to contemporary understanding of persistent pain. The principal aim is to evaluate the pre-post beliefs about pain following a one-day pain education event.

A retrospective observational dual center study investigating side effects and major complications after thoracic epidural insertion according to local safety protocols.

The purpose of the project is to associate pre-treatment pain sensitivity level, levels of pain catastrophizing and levels of The Subgroups for Targeted Treatment (STarT) Back Screening Tool in patients with acute low back pain and patients' progression after 12 weeks of treatment by general practitioners.

The objective of the current study is to prospectively assess the effect of cannabis on pain and functional outcomes in a large group of patients with chronic pain.

Regional anesthesia techniques, with administration of local anesthetics for neuraxial or peripheral route are now playing a central role in modern anesthesia and in particular in the control of postoperative pain. There are many review and meta-analyzes suggesting that a good pain control, and specifically loco regional analgesia, may improve the outcome of patients undergoing surgery. The control of acute post-operative pain is not the only challenge to be paid by anesthesiologists, because there is still much to be understood in relation to persistent post-surgical pain (PPP), and about the degree of influence that regional anesthesia plays in complete long-term functional recovery of patients. From the pathophysiological perspective there is not a precise definition of the mechanisms and risk factors that determine the onset of the persistent pain after surgery, but, more in general, it seems to be related to a malfunction of the mechanism of secondary hyperalgesia. Regional anesthesia could play a key role, as the main determinant of chronic pain is acute post-operative pain. The techniques of regional anesthesia exert a powerful block at the peripheral level, potentially preventing the progression of central pain and the persistence of stimuli that can reach the central nervous system. In addition, during surgery, these techniques can reduce the metabolic alterations and the triggering mechanisms of local and systemic pro-inflammatory mediators' release. Few perspective studies exist about the influence of regional anesthesia on long-term outcome and persistent pain after surgery. The objective of the investigators study is to assess in a prospective fashion the role of regional anesthesia/analgesia technique in preventing (or not) persistence pain occurrence after surgical interventions which are mostly associated to pain persistence, and understand if regional anesthesia provides advantages in other post-surgical outcomes.

The purpose of this study is to evaluate the impact of extended release tramadol hydrochloride (75 mg) and acetaminophen (650 mg) tablets on improvement of pain.

In the present study the investigators aimed to investigate the relationship between surgical methods and chronic pain in over 20 000 patients who underwent groin hernia repair in Sweden

08-SMI-2012 is a post market, observational, questionnaire based study to assess the effectiveness of the commercially available Axium neurostimulator in the management of intractable, chronic pain.

Preliminary results from an ongoing cross-sectional survey of nine of the BraveNet Outpatient Clinics indicate that pain was the leading reason for patient visits. As a precursor to a large multi-site clinical trial, this study aims to determine the feasibility of collecting outcomes data on integrative treatment for pain. These preliminary data will also provide an estimation of effect size for powering the multi-site clinical trial.
