Filter by:This study is designed to explore if the valve-gated pump requires less drug to manage subject pain than the prior standard peristaltic pump in the same subject. The newly implanted valve-gated pump will be programmed to deliver a minimum dose reduction of 20% of the same medication that was delivered in the peristaltic pump prior to explant. The drug therapy will be evaluated and pain scores will be evaluated over time (3 refill cycles prospectively for the valve-gated pump and 6 months retrospectively for the peristaltic pump).
Previous studies have reported that asthmatic or chronic pulmonary obstructive disease patients have an increased response to pain stimulus. However, this aspect has not been evaluated in allergic patients. Additionally, the difference in pain sensitivity between asymptomatic period crisis have not been evaluated yet.
To identify biological and phenotypic prognostic markers of recovery vs. persistence of pain and functional disability in adolescents with chronic musculoskeletal pain.
Non-invasive brain stimulation techniques, transcranial magnetic stimulation (TMS) and transcranial focused ultrasound (FUS), is be applied to healthy human subjects, acute pain patients, and chronic pain patients to investigate their uses for pain relief.
The experience of pain is more than the conscious perception of nociceptive signals. Emotional and motivational aspects accompany pain, leading to its aversiveness and motivation for avoidance. In chronic pain, a negative hedonic shift has been proposed that is characterized by disproportionally increased emotional-motivational compared to sensory-discriminative pain responses. Such a negative hedonic shift is, for example, mirrored in very high comorbidity rates of chronic pain and affective disorders such as depression and anxiety. The aim of this study is to develop methods that allow the differentiation of sensory-discriminative and emotional-motivational pain response and to characterize mechanisms of the negative hedonic shift.
Psychological factors such as stress, distress, anxiety, depression, and poor coping strategies may be associated with ongoing pain following injuries such as fractures. To study this relationship, patients will undergo cognitive behavioural therapy (CBT) which is designed to modify such thoughts with the goal of reducing ongoing pain and improving quality of life. The goal of this study is to determine if CBT, versus usual care, reduces the prevalence of moderate to severe persistent post-surgical pain (PPSP) over 12-months post-fracture in patients with an open or closed fracture of the appendicular skeleton, treated with internal fixation.
Failed Back Surgery Syndrome is described as chronic pain in the low back and/or legs after a spinal procedure. It is estimated that %10 - 40 of the patients who had spinal surgery will have Failed Back Surgery Syndrome. The aim of this study is to research whether intradermal injection of the local anesthetic on the operation scar area and the area in which pain referred to in patients with Failed Back Surgery Syndrome has effects on pain and functionality or not.
Persistent pain is a public health epidemic. The current protocol seeks to develop technology to aid patients' tracking of patients' pain, medications and pain-related variables. The investigators seek to talk with patients in co-investigator's clinic to solicit feedback, as well as pilot test the technology with pain patients.
This study will collect high-quality data on how practicing primary care physicians across the U.S. currently manage patients experiencing chronic pain and how the results of Ethos Laboratories' test change clinical decision making. To do so, this study leverages simulated patient cases called Clinical Performance and Value vignettes (CPVs) in a proven methodology to rapidly measure physician care decisions.
Marginalized populations are at increased risk of chronic pain, trauma and use of street drugs to manage this suffering, with the associated risk of overdoses. Non-pharmacological options to manage chronic pain are difficult for this population to access. myoActivation® is an innovative structured assessment and therapeutic approach. This study will be conducted in the Vancouver Community Primary Care Chronic Pain Service and will include myoActivation and physiotherapy. The study will include sixty patients who seek care on a Tuesday, the only day that myoActivation is offered, and will examine the impact of these treatments on pain outcomes, function and quality of life.
