Active clinical trials for "Nociceptive Pain"

This study is designed to evaluate the effectiveness of a proprietary nutritional supplement that contains Krill Oil (KO), astaxanthin (AX) and hyaluronic acid (HA) to reduce pain and discomfort in participants, compared to an inert placebo (palm oil) control and to a positive control (glucosamine-chondroitin). The purpose of the study is to determine if the combination of KO, AX, and HA will benefit participants with joint pain.

If the individual patient's pain is assessed and the amount of analgesic needed after surgery is predicted, appropriate injection of pain control and excessive injection of narcotic analgesic can be prevented. Therefore, investigators try to evaluate the degree of pain during surgery and the amount of analgesic use for management of postoperative pain.

Assessing pain in the adult intensive care unit (ICU) is challenging because many patients are unable to communicate due to mechanical ventilation and sedation. Therefore, it is necessary to have alternative methods to assess pain in this vulnerable patient population. In this project, the use of a multi-parameter technology (i.e., the Nociception Level (NOL) index) will be tested for pain assessment in ICU adults. The NOL index is a value from 0 to 100 obtained by calculating different parameters (e.g., pulse, skin temperature) captured through a small probe placed on the patient's finger. The NOL was initially developed for assessing nociception, pain and analgesia in anesthetized patients undergoing surgery, and its use in the ICU is new. The NOL's use before, during and after standard care procedures known to be painful (e.g., tube or drain removal, suctioning of secretions through the endotracheal tube) and non-painful (e.g., cuff inflation to measure blood pressure, soft touch) in ICU adults. The NOL will be monitored in three groups: a) patients able to communicate so they can self-report their pain (gold standard criterion) and express behaviors, b) patients unable to communicate but express behaviors (reference criterion), and c) patients unable to communicate and to express behaviors. In the first group, patients will be asked to self-report their pain and procedural distress on a 0 to 10 scale. In the first and second group, patients will be assessed for pain using a standardized behavioral scale which will be completed by trained research staff. In the third group, only the NOL will be monitored. Analgesic and sedative medication administered to patients will also be documented from medical charts. The ability of the NOL to detect pain based on self-reports of pain and behavioral scores, and its ability to discriminate between painful and non-painful procedures will be examined. If found to be useful, the NOL could be used as an alternative measure of pain and improve its recognition and treatment in vulnerable ICU patients.

Evaluation and comparison of the skin conductance algesimeter(SCA) and the nociception level index(NOL) in the paediatric population (1-12 years) during surgery with general anaesthesia with bispectral index(BIS) in a tertiary hospital in The Netherlands.

The goal of this preliminary prospective and observational study is to use hd-EEG (high density electroencephalogram) to investigate how functional and network markers of consciousness are associated to nociception during general anesthesia. More specifically, the aim of this study is to characterize whole-brain functional connectivity and network changes induced by noxious stimulation, and adapt these findings to a clinically-applicable EEG (electroencephalogram) montage.

It was well known that the mirror therapy could decrease pain of upper-limb amputated patients. The mirror therapy is known to make a plastic change some parts of the brain perceiving the painful body part and modulating its signal by feedback of visual information mirrored with the corresponding contra-lateral normal parts. In this study, post-operative analgesic efficiency of the virtual reality using a mirror therapy after total knee arthroplasty will be evaluated. This clinical trial will be performed in the form of prospective, single-blind (i.e. assessor-blind), parallel group, randomized (allocation ratio 1:1), single cohort.

Pain in the neck is a musculoskeletal disorder that affects many individuals. Dry needling has shown an effective technique for the treatment of shoulder and neck disorders. The mechanisms of action of the dry needling are not well-known. This study aims to evaluate the effects of dry needling in the upper trapezius on the autonomic nervous system and nociceptive pain processing in patients with non-specific neck pain. Hypothesis: Dry needling applied in the upper trapezius in patients with non-specific neck pain produced greater activation of the autonomic nervous system and nociceptive pain processing than sham dry needling.

Chronic axial low back pain is a public health problem and has a high socioeconomic impact. The dorsal ganglion of the second spinal nerve (GDL2) is a cluster of neuronal bodies responsible for sensory afferent inputs from more than 80% of the lumbar region. Low-level laser therapy (LLLT) is proven effective to help relieve pain. Thus, the aim of this project is to determine the effect of LLLT on GDL2 when applied to assist in the diagnosis and treatment of chronic axial low back pain. Methodology: 45 patients will be randomized into three groups: laser, radiofrequency and local anesthetic. The patient will be positioned in a prone horizontal position under anesthetic monitoring. The intervertebral foramen between the second and third lumbar vertebrae will be accessed by percutaneous puncture guided by fluoroscopy. In the local anesthetic group, injection of 1 ml lidocaine without vasoconstrictor will be applied in the tubes G20, 150 mm long and 5 mm active tip in contact with the target. In the radiofrequency group, neuromodulation will be held for 300 seconds at 42oC. In the laser group, the laser Photon III® (DCM) will be applied through optic fiber crossing G18 cannulas, during 84 seconds. The pain score will be assessed by visual analog scale. Temperature will be measured and aspirate periganglionic sample, trans-operatively, to study Interleucins-1β and TNF-alpha assessed by ELISA and genetic evaluation trough RNA seek, RNA isolation and ATP quantification. The data will be evaluated for normality and subjected to appropriate statistical analysis, in order to seek representation, as same as the level of significance of the studied samples.

This prospective randomized clinical trial evaluates the effects of a monitor-guided opioid analgesia during general anesthesia. To date no standard-monitoring device exists to specifically reflect the analgesic component of general anesthesia. Quality and safety of general anesthesia are of major clinical importance and should be improved by limiting the opioid analgesic's dosage to the minimum amount needed. The study compares the effects of monitoring nociception during general anesthesia with different innovative techniques in comparison to routine clinical practice.

In this randomized controlled study, investigators planned to investigate the efficacy of oral occlusive splint and therapeutic home exercises in increasing the quality of life and reducing somatic and neuropathic pain in patients with temporomandibular joint dysfunction, determine their effects on other clinical data, and report long-term outcomes
