Filter by:The goal of this clinical trial is to learn if positive airway pressure (CPAP) therapy works for blood pressure (BP) control in obstructive sleep apnea (OSA) adult patients plus undiagnosed hypertension (HBP), using a cuffless bracelet for continual optical BP monitoring (AKTIIA OBPM). It will also learn if CPAP improves cardiac function in these patients using speckle tracking echocardiography (STE) and to learn about ease of use and patient experience with AKTIIA device and AKTIIA OBPM. The main questions it aims to answer are: - Does CPAP reduce systolic BP (and other BP metrics) in this population? - Does CPAP improve cardiac function in the same population? Researchers will compare BP metrics derived from AKTIIA OBPM and STE metrics in a before and after CPAP therapy to evaluate its therapeutic effect. Participants will: - Take a CPAP titration and telemonitoring program for 12 weeks (from the titration date) - Take an AKTIIA OBPM one week before CPAP and 12 weeks since CPAP titration date - Take a STE test twice, before starting CPAP and 12 weeks after CPAP titration date - Take an online survey about easy of use and patient experience with AKTIIA OBPM device
The purpose of this 32 week study is to use an innovative experimental design known as SMART (Sequential Multiple Assignment Randomized Trial), which will allow us to determine the best way to sequence the delivery of teleexercise (referred to as an adaptive intervention), combined with predictive analytics on participant adherence in a stepped program of physical activity interventions. All 257 participants will have access to a library of recorded video exercise content, and a weekly wellness article. Some participants will receive health coaching calls (1st randomization). Analytic data will be used to determine which participants are responding or not responding to the intervention. Participants not responding after 4 weeks will receive either live one on one or group exercise training (2nd randomization). After 8 weeks, the participant will receive only pre recorded exercise content and articles for another 8 weeks. After final surveys, participants will have open access to the website for another 16 weeks where we will passively observe their fitbit and website data. The study outcomes are: The effectiveness of the adaptive interventions Exploring mediating and moderating variables Sensitivity analysis of the predictive analytics
Traumatic brain injury is one of the most common reasons for visits to the Emergency Department. More than 90% of patients who have suffered from head trauma present with a mild traumatic brain injury. Most of these patients do not present any symptom at the time of diagnosis thus delaying the detection. CEREBO®, a non-invasive, portable, rapid, point-of-care intracranial haemorrhage detector can avoid delayed detection by decreasing the time from injury to the initial CT scan. The study aims at assessing the summative usability of the device by determining its ease of use, ease of learning and satisfaction among the medical health professionals. The participants will be trained before the study and will be assessed periodically. Each participant will use the device on at least 10 subjects.
The effectiveness of convectional vestibular training for balance and dizziness rehabilitation in people with multiple sclerosis has been recently demonstrated in a meta-analysis by this research team (doi: 10.3390/jcm9020590). Furthermore, non-immersive virtual reality-based environments seem to be useful for balance and gait rehabilitation in this population (doi: 10.1177/0269215518768084). However, nothing is known about the feasibility and effectiveness of immersive virtual reality-based rehabilitation in people with multiple sclerosis. The primary aim of this research is to determine the feasibility, safety and effectiveness of an immersive virtual reality-based vestibular training for dizziness, balance and fatigue rehabilitation, compared to conventional vestibular training.
The goal of the study is to assess the usability and satisfaction of an electronic patient reported outcomes (e-PRO) mobile application. The secondary aim is to assess and compare response rates between two study groups (e-PRO group vs REDCap survey group). A potential differentiating factor between delivering surveys via smart phone and other electronic modes of delivery is the perceived advantage of being able to conveniently complete survey questionnaires at any time and any location. This could help address certain limitations of the quantitative survey method such as recall bias. Furthermore, the portability, connectivity and ubiquity of smartphones may reduce the amount of training or instructions required for users to complete a survey questionnaire on a smartphone.
