Filter by:The goal of this clinical trial is to evaluate the effectiveness of an 8-week online yoga intervention in improving the well-being and productivity of desk-based workers. The main questions it aims to answer are: - How effective is an 8-week online yoga intervention in improving the well-being (mental and physical) and productivity (work engagement and job performance) of the yoga group compared with passive controls? - Are there any differences in well-being and work-related measures between the yoga and control groups? Participants in the yoga group will practice yoga three days a week for 8 weeks and will be compared with a wait-listed control group, which will continue with the usual routine for 8 weeks. Researchers will evaluate the impact of yoga on the well-being and productivity of desk-based workers.
The goal of this clinical trial is to explore the impact of a 16-week aerobic exercise regimen on the autonomic nervous system and endothelial function in patients with compensated cirrhosis who maintain sedentary lifestyles. The primary research question is: 1) What effect does 16 weeks of aerobic exercise have on changes in the autonomic nervous system and endothelial function in cirrhotic patients? Additionally, the secondary research questions are: 1. How does a 16-week aerobic exercise program influence changes in muscle mass, muscle strength, and physical performance in cirrhotic patients? 2. Is there a correlation between muscle mass and parameters of the autonomic nervous system in cirrhotic patients? Participants in the intervention group will undergo 150 minutes of moderate aerobic exercise per week for 16 weeks, accompanied by a personalized nutritional plan (1.2 grams of protein per kilogram of ideal body weight per day and a calorie intake of 35 kilocalories per kilogram of ideal body weight per day). The control group will solely receive nutritional guidance and maintain their sedentary lifestyle. The researchers will compare outcomes between these two groups.
This study adopted an experimental research design to explore the effects of a warm water foot bath program on fatigue, sleep, and heart rate variability in patients with heart failure. The subjects of the study were heart failure patients in the cardiology outpatient department. The patients were randomly assigned to the experimental group and the control group. The control group received routine care and wore an actigraph. The experimental group received 4 additional care in addition to routine care and wearing an actigraph. Weekly warm water foot bath, data collection includes subjective sleep quality and fatigue level, physiological measurements: sleep quality-sleep time and efficiency, and heart rate variability index.
The goal of this Randomized Controlled Trial is to evaluate heart rate variability (HRV)before and after listening to music in patients scheduled for cataract surgery under topical anesthesia, compared to patients who do not listen to music. Our hypothesis is that the anxious population with a low HRV benefits from an anxiolytic effect of music to increase HRV levels.
A comprehensive study examining the physiological, emotional and psychological aspects of stress among Korean adults
We will assess stress using heart rate variability during examination on medical student. Three time of measurement will be performed. First standardized objective clinical examination, second classic table examination and third a control day.
Specific aims - To test the effects of a relaxation and guided imagery intervention with socioemotional learning content on a range of socioemotional, physiological, cognitive and academic outcomes of school-aged children, measured through self-reports, neuropsychological and physiological measures, as well as teachers and parent's reports.
In this study, the SCI patients were sub-grouped on the basis of symptoms into symptomatic and asymptomatic groups and measured HRV during resting and tilt up tests to compare their cardiovascular autonomic functions.
- The main goal of this prospective longitudinal observational study is to investigate the psychophysiological indicators by analyzing HRV, blood pressure, symptoms of anxiety and depression, eating behavior and quality of life during the follow-up of the general health status of patients with obesity undergoing the bariatric surgery by Roux-en-Y reconstruction reduction gastroplasty (GRYR) technique. - The main question it aims to answer is: Does bariatric surgery changes the variables studied (HRV, anxiety, depression, eating behavior, quality of life)? - Type of study: prospective longitudinal observational study - Participant population: 50 patients, both females and males, aged between 18 and 60 years, will be submitted to bariatric surgery with Roux-en-Y reconstruction reduction gastroplasty technique. Patients will be evaluated for five times: before the bariatric surgery and 3-6-12-24 months after the bariatric surgery.
The purpose of this randomized controlled trial was to compare the effectiveness of an HRV-BF intervention versus a health promotion active control intervention focused on improving mental health symptoms among people experiencing homelessness (PEH), who were residing in Skid Row, Los Angeles. In total, 40 PEH were randomized to either the HRV-BF or an active health promotion control group, and received 8 weekly, 30-minute sessions over a two month period, delivered by a nurse-led community health worker team. Dependent variables of HRV, mental health, anxiety, depression and PTSD were measured at baseline, the 8-week session, and/or 2-month follow up.
