Filter by:The aim of the study is to evaluate the effect of botox injections at the spermatic cord in patients with chronical scrotal pain. A lot of patients experiences depressive symptoms and a lot feel isolated. The etiology if not fully understood and the condition poses a challenge for physicians. The is no efficient minimal invasive treatment for these patients, and in severe cases patients are having there testicle removed. By inject botox around the spermatic cord the investigators hope to relieve some of the pain in these patients and offer patients a new minimal invasive treatment. The investigators aim to include 50 patients in this study, There will be randomised 1:1 to either the intervention arm (Botox) or control arm (sterile saline). Both patients and physicians will be blinded to the treatment. Patients will undergo a thorough physical examination and will be asked to fill out questionaries to asses their quality of life. After inclusion, patients will be followed closely for three months with physical examination and questionnaires. After three months, patients in the control arm will have the opportunity to cross over to the intervention arm. Data will be reported continuously.
The incidence of postoperative chronic pain after craniotomy is high. Postoperative chronic pain seriously affects patient's quality of life. Compound local scalp nerve block is a good choice for analgesia after craniotomy. However, the scalp nerve block commonly cannot cover the area of suboccipital retrosigmoid approach craniotomy, leading to incomplete block. Superficial cervical plexus block (SCPB) is theoretically promising to solve the analgesia requirements of such surgical approach. At the same time, ultrasound guidance can not only accurately locate, ensure the effect of block and avoid accidental injury during puncture. The purpose of this study is to explore whether ultrasound-guided superficial cervical plexus block can safely and effectively reduce the incidence of chronic pain after craniotomy via suboccipital retrosigmoid approach.
This study is to retrospective investigate the effects of the simultaneous intravenous (i.v.) administration of lidocaine and ketamine on a four to six weeks interval in treatment refractory different chronic pain conditions.
Persistent pain describes long term pain that is present nearly every day. It is common and affects millions of people in the United Kingdom. The investigators want to explore people's experience of living with persistent pain and investigate how pharmacists can help people manage their pain. For this, the investigators will be testing a digital Decision Aid Tool (DAT) that includes a pain and lifestyle assessment as part of a pain consultation.
Refractory chronic pain represents a serious and limiting health condition which does not respond to standard pharmacological therapy. Thus, it emerges the necessity of new techniques to treat these group of diseases, such as the transcranial electrical stimulation (tES). This procedure induces a low-intensity electrical current through the scalp to modify the excitability of brain cells, thus facilitating changes in neural networks which may be dysfunctional in some chronic pain patients. The main objective of this research is to test the efficacy of two tES techniques, differentiated by applying direct or alternant electrical current, to reduce the pain intensity and to increase pain thresholds of these patients. Besides, intervention is implemented at home for patients themselves thanks to a portable and convenient stimulator device, after one training session provided by technicians. Researches can supervise the compliance of the treatment remotely, as the stimulator has a permanent connection with their computers. A home-based approach means a more comfortable and accessible treatment alternative for patients, since they do not have to attend to clinics everyday to receive the stimulation; the advantages become even more relevant in the pandemic context, since the risk of being infected is radically minimized. Despite the main purpose is to test the efficacy of tES to improve the pain suffered by patients, many other areas are considered as secondary end points for being intrinsically linked or affected by the disease, such as the interference in daily tasks provoked by pain, mood disorders (depression/anxiety), fatigue, life quality, physical functioning and sleep quality; these last two variables are measured with actigraph wristwatches, apart from specific questionnaires. Lastly, endogenous modulatory pain mechanisms are examined through sensory tests, namely Conditioned Pain Modulation and Temporal Summation of pain.
This study investigates how adults prescribed opioids for chronic noncancer pain respond to invitations to try non-opioid options of massage therapy, yoga therapy, chiropractic and physical therapies. Due to the COVID-19 pandemic, these options will be available via telehealth consultation visits using a computer or smartphone with internet connection. The investigators will measure effects on pain, pain-related symptoms, and opioid use over time using a single-group design.
In this study the investigators aim to examine the effects of Transcranial Magnetic Stimulation (TMS) on hippocampal network connectivity and pain levels in individuals with pain due to knee osteoarthritis.
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a collective term referring to disorders which is characterized by lower urinary tract symptoms, including bladder pain/discomfort, frequent urination without evidence of bacterial infection. The etiology of IC/BPS is still uncertain, and most current treatment for IC/BPS are only symptoms control. Our previous study revealed Epstein-Barr virus (EBV) infection presented in the IC/BPS bladders and involved the pathogenesis. Hence, using anti-viral medication valacyclovir for the patients with IC/BPS might have clinical efficacy.
This research study is being done to investigate if the GH Method exercise program positively affects body composition, improves physical abilities and can improve the overall sense of wellbeing (e.g. depression, PTSD, etc.) in U.S. Veterans. Subjects will be asked to complete 94 total visits (four (4) study testing visits and 90 exercise visits). Enrolled subjects will be tested for fitness, strength, and health risk factors at UIC 4 times and will complete 90 exercise training visits at the GH FITLab over the next 18 months. Subjects will also be asked to complete questionnaires about depression, post-traumatic stress symptoms and thoughts about harming oneself.
We are investigating the effects of a mind-body based mobile application on the experience of chronic pain. Participants meeting our criteria for chronic pain (confirmed via self-report) will complete an online baseline questionnaire. Eligible participants will be enrolled in the study and randomized into control (usual care, waitlisted) or intervention group (6-week mind-body based mobile application intervention). Randomization will be stratified by pain intensity and gender using computer-generated block randomization to create varying block sizes of 4 and 8. We will run the trial in multiple cohorts in series to obtain desired sample size. All participants will complete online questionnaires at baseline and post-intervention at 6 weeks that measure pain intensity, interference with daily living, pain perceptions, mental health outcomes, and medication use. Participants will also complete weekly questionnaires on weeks 2 to 6 to gauge frequency of application usage (intervention) or other pain treatments (control). Participants in the intervention group will be asked to repeat the follow-up questionnaire at 12-weeks.
