Filter by: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
This study will enroll approximately 100 HIV-negative persons, aged18-45 years, and assigned female sex at birth from sites in the United States, Kenya, South Africa, and Zimbabwe. The study will assess the acceptability and safety of two placebo vaginal films. The placebo films do not contain any active medication, are the same size, but differ by shape (square versus rounded corners). Participants will be randomly assigned to one of the two films and asked to use (self-insert) the assigned film two times (approximately one month apart). Participants will be asked to refrain from sexual activity during the first month of use and may resume usual sexual activity during the second month of use. The study involves answering questions, undergoing pelvic examinations, and collecting blood and vaginal fluid samples. The study involves a total of 10 visits/contacts, including in person visits and telephone calls over approximately 9 weeks. In addition, both participants and approximately 30 of their sexual partners will be asked to take part in in depth interviews to further assess acceptability, attitudes, and experiences with film use to gauge interest in the future use of vaginal films as a HIV prevention option.
This study aims to test the efficacy of an information visualization dashboard on decision-making using a randomized controlled trial with crossover. This study aims to test the efficacy of using an information visualization dashboard on ICU providers' decision-making, efficiency, and performance compared to their institutional EHR through a randomized control trial with crossover.
Pilot study to evaluate the effect of prehabilitation programme through a mobile application PREHapp in colon cancer surgery. The objectives of this pilot study were to evaluate the usability of the PREHapp for people undergoing colon cancer surgery, estimate the effect of the app on functional recovery after surgery and to evaluate complications during the postoperative period after 4 weeks of follow-up.
Currently there is one Levodopa inhaler on the market, the INBRIJA® inhaler. When looking at the user instructions for the INBRIJA®, multiple steps are necessary including preparing and cleaning the inhaler. The Levodopa Cyclops™ inhaler also requires steps to be ready-for-use, however there are less steps required to reach this 'ready-for-use' state. This is mainly because the medicine (Levodopa) is already prefilled in the inhaler. Moreover, the Levodopa Cyclops™ is a single-use inhaler and cleaning steps are not necessary. Since both inhalers should be used during off episodes, there might be a preference for one inhaler over the other due to the instructions. An off episode might impair the ability and length to successfully operate an inhaler due to mental or mobility issues. This study investigates if Parkinson patients have a preference for one of the inhalers based on handling steps, ease-of-use, understandability.
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.
This research will contribute to therapeutic technology to support bereaved parents who have experienced a perinatal loss. The proposed mobile application would accomplish this objective by providing a series of therapeutic modules to provide parents with tools to normalize their grief and additional coping skills to support the grieving process.
The primary objective of this study is to evaluate the satisfaction of users with the MySOLIUS device by a non-professional in a home use environment. The secondary objective of this study is to demonstrate the safety and effectiveness of the MySOLIUS device in the improvement of mood/quality of life score.
The purpose of this study is to evaluate the usability of the system which includes the wearable device, app and cloud data processing, including an algorithm (Aura) capable of detecting possible early signs of respiratory infections in healthy individuals. In addition, the investigators would like to evaluate the presence of any allergic reactions to materials used in the manufacture of the EmbracePlus.
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.
