Filter by: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.
Nociceptin/Orphanin is a novel opioid peptide system associated with inflammatory response. Currently is it uncertain as to the presence of absence of nociceptin in synovial fluid of patients. Nociceptin levels will be measured pre-operatively and post-operatively in plasma levels of patients receiving primary total knee arthroplasty. Nociceptin levels will also be measured in synovial fluid levels prior to surgical manipulation.
In a randomized control trial and single blinded study, tender spots were identified in 150 participants' plantar flexor muscles (gastrocnemius or soleus). Then participants were randomly assigned to one of five intervention groups (n = 30): 1) heavy rolling massage on the calf that exhibited the higher tenderness (Ipsi-R), 2) heavy rolling massage on the contralateral calf (Contra-R), 3) light stroking of the skin with roller massager on the calf that exhibited the higher tenderness (Sham), 4) manual massage on the calf that exhibited the higher tenderness (Ipsi-M) and 5) no intervention (Control). Pain pressure threshold (PPT) was measured at 30 seconds and up to 15 minutes post-intervention via a pressure algometer.
We will conduct a randomized controlled trial to determine whether the addition of battlefield auricular acupuncture to standard of care is effective for control of postpartum pain for mothers in the immediate post-partum period. Post-partum patients (DoD beneficiaries) 18 years or older, regardless of gravida/parity, who plan to have a childbirth in a hospital setting will be offered the opportunity to participate in the study through PCM referrals and posted advertisements. After a minimum of 6 hours post-vaginal delivery or 24 hours post caesarean section subjects will be given treatment according to their randomization group. Subjects will be assessed on pain control, overall satisfaction with pain management, and the amount of pharmacological pain medications used. Safety of measures will also be assessed to include infection rates, syncope, vertigo, and hypotension.
The TEACH patient cohort will characterize a clinic sample of HIV-infected patients on chronic opioid therapy (COT) by describing basic demographics and health status, including characteristics of pain (severity and interference), aberrant behaviors/misuse of COT, substance use and trust/satisfaction with providers. In addition, data on a subset of participants will be used to supplement analysis of secondary outcomes for the TEACH randomized controlled trial (RCT), an intervention study directed at COT providers (outlined in a separate Clinical Trials Protocol Registration and Results (PRS) summary).
The purpose of this study is to determine if there is a difference in pain perception by participants when the assistant port size varies by 50% (8 mm to 12 mm).
This pilot clinical trial studies how well a mindfulness-based stress reduction (MBSR) intervention works in reducing anxiety in patients who have undergone treatment for gynecologic cancer but no longer have any sign of disease. Gynecologic cancer is cancer of the female reproductive tract, which includes the cervix, endometrium, fallopian tubes, ovaries, uterus, and vagina. Side effects from treatment for these cancers may include anxiety, fatigue, depression, and sexual function changes. Mindfulness training uses meditation and yoga to help patients focus on breathing, bodily sensations, and mental awareness. This may help decrease patients' stress and anxiety and improve their quality of life, and may also help their immune system.
The purpose of this study is to determine the effects of pain on facilitating long-term auditory memory in the presence and absence of distinct intravenous anesthetics. The ability to identify previously presented words from a list assessed the degree of memory formation. In a subset of subjects, functional magnetic resonance imaging was used to identify the neural correlates of memory inhibition or facilitation by the combination of pain and anesthetic used.
A randomized double blind control trial to investigate the safety and efficacy of subcutaneous ketamine for control of post operative pain in low resource settings.
All pediatric patients who undergo cardiac surgery require analgesic medications for postoperative pain control and many require sedation to facilitate comfort with cares. Parasternal infiltration of local anesthetic for nerve blocks is a simple option to postoperative analgesia. The investigators hypothesize that Bupivacaine, a parasternal nerve block administered in pediatric patients undergoing cardiac surgery will reduce the requirement of Opioids and other pain medications as well as decrease postoperative pain scores. This is a prospective, double-blind, randomized controlled trial. Subjects are randomized to receive either 0.25% Bupivacaine or normal saline following their cardiothoracic surgery.
