Filter by:Severe and refractory pain after acute injury is a known-risk factor for chronic opioid use disorder. In this study, the investigators will use Virtual Reality (VR) immersion as a non-pharmacological adjunct to treat pain associated with acute traumatic injuries, including traumatic brain injury. The investigators hypothesize that VR therapy will decrease pain and reduce opioid use in patients with acute traumatic injuries, including TBI.
This study was carried out to determine the effect of listening to music and acupressure application in reducing pain and anxiety during gynecological examination.
This is a randomised, double-blind, placebo controlled study to evaluate the efficacy of Methoxyflurane (Penthrox®) for the treatment of acute pain during closed nasal fracture reduction. The study aims to provide evidence under blinded controlled conditions that Penthrox is safe and effective in patients aged 18 to 65 years during closed nasal fracture reduction.
Pain is common and can contribute to both psychological and physiological effects if not treated. Currently primary care paramedics have limited selections within their pain management tool box. This contributes to inadequate pain management. Methoxyflurane is a safe, easy and effective choice in prehospital management of pain. The impact of this feasibility trial, will hope to inform the larger multi-centred trial and then support the implementation of out-of-hospital Canadian National Guidelines for prehospital pain control, enabling paramedics to provide rapid, effective prehospital pain relief to patients.
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.
Medical and dental patients may experience fear commonly attributed to physical pain during the visit. By reducing pain perception, patient comfort and future patient compliance may be improved. Patient health may be improved by increasing compliance and promoting increased visits. This can lead to more frequent and timely preventative actions. The research purpose is to establish quantitative and qualitative data to support current, non-pharmacological methods for reducing pain sensitivity. More specifically, the investigators aim to determine if the use of auditory and visual (3D imaging) stimuli related to the regulation of breathing can decrease or modulate pain. Healthy participants between the ages of 18 and 60 will participate in a one week study, with two in lab appointments on day one and day seven. Participants will be split into two groups, one will undergo breathing awareness using auditory and visual technology (i.e. listen to one's own breathing with headphones and watch 3D image of lungs using virtual headset), and the second group will have breathing awareness without the use of technology (i.e. simply focusing on one's own breathing). At each appointment, the investigators will collect pain threshold data using thermal Quantitative Sensory Testing (tQST) and brain activity data using Functional near-infrared spectroscopy (fNIRS). tQST and fNIRS data will be collected before, during, and after each breathing awareness/control exercise. Quantifying change in pain intensity has been demonstrated by pain threshold comparison across a stimulus using thermal Quantitative Sensory Testing (tQST). Functional near-infrared spectroscopy (fNIRS) in coordination with pain stimulation has been shown effective at locating different hemodynamic cortical responses depending on pain perception and expectation. In the current study, functional resting states before and after pain stimulation will be quantitatively assessed using fNIRS. The study design will allow the investigators to determine if the use of auditory and visual (3D imaging) stimuli related to the regulation of breathing can decrease or modulate pain. Cortical responses will give additional insight into the areas related to the decreased pain threshold. The long term objective is to increase neurophysiological understanding that will improve patient care. If effective, the novel experimental methods used will help to standardize future pain evaluation techniques.
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.
The purpose of this study is to evaluate the analgesic effects of cannabidiol for patients who have undergone simple tooth extraction. Participants will be randomized to one of four arms: treatment-as-usual (TAU), cannabidiol 17mg/mL, cannabidiol 37mg/mL, or placebo.
Sodium hypochlorite is a commonly used irrigation agent. However, the solution may extrude beyond the apex of tooth and cause pain during the treatment.The aim of this prospective observational investigation is to determinate the frequency of the extrusion of sodtium hypochlorite in endodontically treated teeth.
