There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Every year, thousands of Canadians are diagnosed with degenerative cervical myelopathy (DCM), a form of non-traumatic injury caused by spinal cord compression in the neck. While DCM causes a range of symptoms, one of the most disabling is loss of hand dexterity. Surgical decompression is standard treatment for DCM, but reduced dexterity often remains. The investigators have developed a portable, easy-to-use dexterity assessment tool for measuring hand dexterity. Hand function is often assessed using tools incapable of measuring subtle changes in function, limiting a clinician's ability to monitor progression of or recovery from a disease over time. The hope is that if subtle changes in function are identified early, leading to an early DCM diagnosis and treatment, this may prevent patients from experiencing a greater loss of hand function. The goals of this study are to determine the relationship between dexterity and myelopathy severity, as well as to establish the validity and reliability of the dexterity tool. This will be done by assessing dexterity using the dexterity tool in DCM patients (to determine the relationship between disease severity and dexterity, and measure validity) and healthy participants (to establish reliability).
The goal of this trial is to test a debriefing protocol to improve non-technical skills (NTS) in medical students. The study aims to answer the following questions: - Does a debriefing intervention improve medical students' NTS? - Does the intervention have an impact on the students' performance in simulated scenarios? Participants in the study will be randomly assigned to one of the teams, each consisting of a trauma team leader and three assistants. The teams will rotate across four different scenarios, allowing participants to switch roles and act as team leaders. The intervention teams will be debriefed using the study protocol, while the control groups will receive standard technical feedback without focusing on NTS. The primary outcome measure will be the Non-Technical Skills for Surgeons (NOTSS) score, which is a validated assessment tool for NTS. Secondary outcome measures include the number of correct interventions performed in each scenario. The study will involve 40 medical students, and the sample size was determined based on previous studies and statistical considerations. A panel of health educators will define the debriefing protocol, and the trial has been approved by the McGill Research Ethics Board office. The study findings are expected to contribute significantly to the training of providers of trauma care for children worldwide. By exploring the impact of debriefing on NTS in pediatric trauma education, this project aims to fill a critical gap in current training models.

Background: Magnetic resonance imaging (MRI) has been known for almost forty years to generate fear and anxiety. Children may become restless during scanning, which results in movement artifacts requiring the MRI to be repeated with sedation. Very few studies seemed to have looked at the effect of immersive virtual reality (IVR) on anxiety in children scheduled for an MRI. Objectives: The aims of this study are two-fold: 1- to address feasibility and acceptability of a pre-procedural immersive VR (IVR) game preparation for anxiety management during MRIs and 2- to examine the efficacy of IVR game preparation compared to usual care for the management of procedural anxiety during MRIs. Methods: This study will first consist of a field test phase with 10 participants, aged 7 to 17 years old, to address the feasibility and acceptability of the use of virtual reality. Following the field test, a RCT will be completed using a parallel design with two groups: 1) experimental group (pre-procedural IVR game preparation), 2) usual care group (standard care as per radiology department's protocol) in an equal ratio of 49 participants per group for a total of 98 participants. Recruitment will be done at CHU Sainte-Justine's, Quebec, Canada. The experimental group will receive a pre-procedural IVR game preparation (IMAGINE) that offers an immersive simulation of the MRI. Participants will complete a questionnaire to assess the acceptability, feasibility and incidence of side effects related to the intervention and the biofeedback device. Data collected will include socio-demographic, clinical characteristics, measures of anxiety with the French-Canadian version of the State-Trait Anxiety Inventory for Children (STAIC-F) and the Child Fear Scale (CFS, 0-4). Physiological biomarkers of anxiety such as alpha-amylase and other markers such as heart rate and head deviation will also be measured. Measures of healthcare professionals, parents, and participants' level of satisfaction will also be collected. Analyses will be carried out according to the intention-to-treat principle, with a significance level (α) of 0.05. Discussion: Our study provides an alternative method for anxiety management to better prepare patients for an awake MRI. It will guide future medical practice by providing evidence-based knowledge on a non-pharmacological therapeutic modality for anxiety management in children scheduled for an MRI.
This study will examine the effectiveness of the PelvicSense 3-month online program on pain and other outcomes in those with endometriosis. This study is prospective in nature and will involve several assessment points: baseline, immediately post-treatment (at the end of the 3 month program), and 3-month follow up. All aspects of the study will be conducted remotely (e.g., online, email, video calls), and participants will be at least 18 years of age, fluent in English, and experience pain due to endometriosis for at least 3 months with a physician diagnosis. Participants are expected to continue their treatment as usual and this information will be documented throughout the study.

This study is prospective in nature and will involve several assessment points: baseline, immediately post-treatment (at the end of the 3 month program), and 3-month follow up. All aspects of the study will be conducted remotely (e.g., online, email, video calls), and participants will be at least 18 years of age, fluent in English, and experience pain due to provoked vestibulodynia for at least 3 months with a physician diagnosis. Participants are expected to continue their treatment as usual and this information will be documented throughout the study.
Neurogenic orthostatic hypotension (nOH) is a chronic condition associated with increased cardiovascular risk and reduced quality of life. On standing, patients with nOH experience a large reduction in blood pressure (BP; at least ≥20/10mmHg, but often much more), which is often accompanied by debilitating symptoms and syncope. A previous study (unpublished) showed that hypercapnia significantly increases standing BP in patients with nOH. Human bodies naturally produce and exhale CO2. Rebreathe devices offer a simple, cost-effective technology to increase arterial CO2. In brief, rebreathe devices work by capturing expired CO2, which is then re-inhaled. The net effect is a transient increase in CO2. A CO2 rebreathing device may offer a novel hemodynamic therapy for patients with nOH. This is a pilot, proof-of-concept study to evaluate a CO2 rebreather to improve blood pressure and orthostatic tolerance in patients with nOH. The hypothesis is that a rebreather will increase CO2 sufficiently enough to improve BP in patients with nOH. Male and female patients (n=28) will be asked to complete two randomized 70° head-up tilt (HUT) tests breathing either room air or using a CO2 rebreather. Hemodynamics (BP, heart rate, stroke volume, brain blood flow) and orthostatic symptoms will be assessed throughout. Breath-by-breath data will include O2, CO2, respiration rate and tidal volume. The primary outcome measure will be the magnitude of the BP response (ΔBP = HUT - Supine) during Room Air vs. Hypercapnia. The primary outcome will be compared between room air and hypercapnia using a paired t-test.
This is a prospective longitudinal cohort study whereby pregnant individuals are asked to complete an 8-day testing protocol to measure their sleep and cardiovascular health at two timepoints during pregnancy.
The goal of this interventional study is to compare training for different numbers of days each week in healthy, young individuals. The main questions it aims to answer are: - Does exercising less often improve endurance fitness as much as exercising more often? - Are endurance fitness improvements caused by improvements in the muscle and blood? Participants will train on a stationary bike for eight weeks. Researchers will measure the participants endurance fitness, as well as muscle and blood characteristics, before and after training to look for improvements from the training protocols. Researchers will compare low-frequency exercise (two times per week) and high-frequency exercise (four times per week) to see if they each improve endurance fitness.
