Filter by:The purpose of the study is to assess the feasibility of using information extracted from physiologic signals to automatically adjust stimulation in patients undergoing Spinal Cord Stimulation (SCS).
Pulsed radiofrequency applied to the dorsal root ganglion (DRG) is an interventional treatment alternative in the treatment of lumbar radicular pain that does not respond to conservative methods. Under intermittent fluoroscopic imaging, the location of the ganglion can be determined by administering contrast media. We consider that determining the localization of the ganglion with this method during pulse radiofrequency application can shorten the procedure time. In this way, we believe that it would help the correct application of the procedure.
The goal of this unique 18 month study is to better understand the experiences of pain patients in the Royal University Hospital (RUH) Emergency Department (ED), to create excellence in health care. The purpose is to measure the impact of visiting therapy dogs on reducing ED patient pain.
The purpose of this study is to evaluate and compare the therapeutic efficacy of intermittent Dorsal Root Ganglion Stimulation (DRG-S) to standard continuous stimulation in patients with chronic intractable pain
Observational study to assess efficacy of IV ketamine bolus when used in the post anesthesia recovery unit for uncontrolled pain despite use of opioids.
A number of studies from the literature suggest important behavioral, psychosocial, or radiologic changes occur following significant neurologic events or interventions such as stroke, neurosurgery, medications, radiation, systemic therapy, or injury. The purpose of this study is to describe these changes with advanced neurologic imaging and targeted neurologic and neuropsychiatric assessments. This is a non-interventional observational study of minimal risk to participants as there is no medical intervention. The results of this study will be used to inform patients, scientists, and society in the development of future treatments.
Pain is a common symptom in palliative care cancer patients and is often insufficiently relieved. The 2010 INCA report showed that France is not an exception to this worldwide observation (synopsis of the 2010 national survey). This report shows that pain is the symptom that these patients fear the most and that it dramatically impacts their quality of life. These patients may experience nociceptive pain related to stimulation of sensory nerve endings by the tumour. When tumour resection is impossible, a symptomatic analgesic treatment is generally proposed, mainly consisting of administration of opioid analgesics. At high doses, this treatment induces adverse effects, especially drowsiness and psychomotor retardation that impair the patient's quality of life. They may also experience neuropathic pain, secondary to anatomical lesions or functional impairment of nerve structures (peripheral nerves or cerebral or spinal tracts) related to repeated surgical procedures and/or radiotherapy. This type of pain may respond to antiepileptic or antidepressant drugs. At high doses, these treatments also induce adverse effects fairly similar to those observed during treatment of nociceptive pain. As these two types of treatment often need to be coprescribed, these patients frequently present an almost permanent state of drowsiness at the end of life, preventing all normal activities of daily living. In recent years, noninvasive brain stimulation (NIBS) techniques (transcranial magnetic stimulation (rTMS) or transcranial direct-current stimulation (tDCS)) have been successfully used to treat chronic pain. It was shown that these NIBS techniques can improve pain in cancer patients in the palliative care setting.
This study is to assess the efficacy and safety of a four-week treatment with intranasal esketamine (56 mg) twice a week combined with opioid analgesic and adjuvant standard therapy in the management of adult patients with severe and opioid refractory chronic cancer pain.
This multi-modal methods study will investigate neurophysiological, endocrinological, cognitive, psycho-social-emotional markers of chronic pain, and therapeutic targets using integrative health treatments.
Both mindfulness meditation and expectancy effects are known to reduce pain intensity, pain unpleasantness and pain catastrophizing, but it is unknown whether and how expectancy effects contribute to the overall effect of mindfulness meditation on these outcomes, especially during significant global events such as the coronavirus pandemic. This study includes four interrelated aims that will probe these effects and interactions.
