Filter by:In this work the investigators will study the relationship between chronic musculoskeletal pain and abnormal blood flow (neovascularity) around the shoulder, hip and knee. Veterans with as history of chronic shoulder, hip or knee pain and mild/moderate joint degenerative changes will be potential study subjects. Blood flow around joints will be evaluated using perfusion magnetic resonance imaging (MRI). Participants with demonstrably abnormal blood flow around their painful joint will be eligible for enrollment in a pilot study of joint embolization to treat their pain. Participants who choose to not undergo treatment will be re-assessed with MRI after one year to characterize the natural history of joint neovascularity and its relationship to pain.
The primary objective of this study is to determine, in a healthcare setting, the effectiveness of actual tDCS in reducing pain compared with placebo tDCS. This is a multicenter randomized controlled trial with parallel groups (real tDCS vs. placebo) blinded to participants, assessors and tDCS providers. The real tDCS group will receive a daily 20-minute session of tDCS (current intensity = 2 mA), for 5 consecutive days, while the placebo tDCS group will receive an equivalent treatment, but the current will be stopped after the first 30 seconds. The study will take place in 5 rehabilitation clinics in 3 Quebec regions. One hundred and fifty (150) seniors aged 65 years or older with chronic (> 6 months), moderate to severe musculoskeletal pain will be recruited (50 participants/region). Follow-ups will take place at 1 week and 3 months post-treatment. The primary dependent variable is pain intensity (numerical scale from 0 to 10). Secondary variables will be measured using standardized and validated questionnaires: 1) pain-related interferences (physical function, mood, quality of life) and 2) perception of post-TDCS changes. Neurophysiological measures (pain control pathways).
Controlled clinical trial of two parallel groups, with random assignment 1:1, non-inferiority, blinded for the patient, for who administers the intervention and for who analyzes the data. 112 participants
This is an exploratory study investigating the use of virtual reality-based guided mindfulness meditation in improving pain, stress, and mood within various clinical populations. The feasibility of utilizing VR applications within the populations of patients with various specific disease types and clinical settings is a burgeoning area of research. The goal is to establish an association between the use of VR-based mindfulness meditation, and pain, stress, and mood scores.
Head and neck cancers are a source of complications and after-effects related to the disease and treatment. These cancers and their treatment alter the quality of life of patients and generate pain with physical and psychological components. Chronic pain affects 36% of patients at 6 months and 30% after this period. These pains are responsible for the consumption of level II and III analgesics in 53% of these patients. At the same time, after the end of treatment, nearly a quarter of patients continued to smoke and half still consumed alcohol at least twice a week. The hypothesis of this research is to investigate the correlation between pain and the continuation of addictions, the occurrence of depressive states, asthenia and the alteration of the patients' global quality of life. The investigators propose a two-center prospective cohort study to evaluate this hypothesis at 6 months after radiotherapy treatment. This study is planned to include 120 patients with a first head and neck cancer whit radiotherapy as part of their treatment sequence. The expected duration of inclusion is 18 months. The identification of factors affecting survival, quality of life and patient compliance is essential to determine appropriate management, particularly by creating appropriate therapeutic education programs.
Neck pain-associated disorders (NAD) and whiplash-associated disorders (WAD) are major health problems. NAD has a lifetime prevalence of 54%. Although the majority of patients recovers within the first three months, a minority develops persistent pain. WAD, in contrast, is reported less frequently, but patients are often suffering more badly. Patients with chronic symptoms represent a considerable burden in terms of pain, suffering, health care needs, and social costs. Findings on the natural course of NAD and WAD reflect the necessity to identify factors besides pain related to the persistence of symptoms. First, alterations of input and processing of multiple sensory modalities causing movement control impairment can result in persistent symptoms and affect the quality of life. Besides, findings of psychosocial factors predictive of pain outcomes support the growing body of research proposing a bidirectional relationship between somatic and psychosocial variables. In particular, there is a pressing need to investigate pain-related activity patterns, besides fear-avoidance behavior in NAD and WAD. Maladaptive activity pattern have an impact on on pain and disability in the long-term prognosis. Mt important, given the high prevalence of NAD and WAD, the cortical representation of the cervical spine has not yet been investigated and, reports on neuroplasticity remain scarce. These shortcomings should be addressed to provide evidence for the temporal aspect of neuroplasticity and its involvement in pain persistence. Hypotheses: We hypothesize I. that impaired sensorimotor abilities, mental health at baseline increase pain intensity and disability during measurement. II. that maladaptive pain-related activity patterns avoidance and overactivity at baseline are prognostic factors for pain persistence and disability. III. that the WAD cohort shows more depression, anxiety and stress compared to the NAD cohort.
This is study designed to confirm the effectiveness of the Sana Device in patients with pain due to fibromyalgia on quality of life as measured by the Fibromyalgia Impact Questionnaire Revised (FIQR). It is a two arm study in which subjects will be randomly assigned to either active device group or sham-controlled group.
Osteoarthritis (OA) is a chronic and progressive disease that results from characteristic pathological changes in the tissues of the entire joint, resulting in failure in the component parts. OA is one of the most common causes of disability in adults due to pain and altered joint function, impacting patients' quality of life. Treatment is based on decreasing pain and improving function, involving non-pharmacological, pharmacological, and surgical management. First-line treatment involves non-pharmacological and pharmacological measures. When OA is very advanced, total joint replacement surgery is recommended. However, for patients refractory to conservative treatment and unwilling or unable to undergo arthroplasty, few options remain. Recently, several studies involving minimally invasive procedures are being recommended. Among them is the cooled radiofrequency technique, causing neurotomy by thermal activity, thus reducing the patient's perception of pain. The classical therapeutic target for this technique are the genicular nerves of the knee. However, more recent studies have shown that these classical targets do not provide complete pain relief and have suggested new therapeutic targets, comprising besides the genicular nerves, the recurrent peroneal nerve and the infra-patellar branch of the saphenous nerve. In order to validate these revised targets, new studies need to be done. Therefore, the aim of the present study is to evaluate the efficacy of the cooled radiofrequency procedure using classical and revised targets, and to compare pain intensity, knee function, quality of life, analgesic consumption and adverse effects of both techniques. Key words: Osteoarthritis of the knee. Sensory nerve denervation. Classical targets. Revised targets.
This study will be conducted to compare the efficacy of ultrasound guided thoracic interfascial plane block versus ultrasound guided erector spinae plane block on acute and chronic pain after modified radical mastectomy surgery.
The relatively complex anatomical structure of the pelvis has been a focus of study in the medical field. The diagnosis of the causes of chronic pelvic pain is usually a complicated process. Pudendal neuralgia is a syndrome that is characterized by pelvic pain, including bowel, bladder regional pain or discomfort, sexual dysfunction, severe burning sensations and needle-like pain, which are aggravated when seated and relieved after standing. pudendal neuralgias are induced by pudendal nerve damage The mechanism of PRF has been studied repeatedly. It has been verified that PRF has definite safe treatment range, but during the PRF treatment, the tissue surrounding the electrode may have some degree of change and so it is difficult to assess any actual damage.7 Based on electric field intensity, PRF can actually produce tissue changes observable as in vitro changes to ultrastructure in early-phase histologic study. These biological changes were converted to biological effect to alleviate neuropathic pain in animal models.
