Filter by:This study looks at how auricular vagus nerve stimulation (AVNS) affects neck pain, heart rate variability, and balance in college athletes, additionally, if different settings of auricular vagus nerve stimulation (AVNS) affect neck pain, heart rate variability, and balance in college athletes. The participants will be split into two groups, each receiving AVNS with different settings. The study hypothesizes that vagus nerve stimulation (VNS) will reduce pain perception in college athletes. It is expected that auricular vagus nerve stimulation (AVNS) will decrease heart rate variability (HRV) in this population. Additionally, it is anticipated that college athletes undergoing AVNS will exhibit improved balance. The Investigators also believe that AVNS will decrease neck pain and enhance neck function. Finally, it is proposed that different AVNS parameters will have varying effects on pain intensity, HRV, and balance in collegiate athletes.
Perinatal depression is a highly prevalent and serious health issue during pregnancy. According to statistics, approximately one out of every ten postpartum women experiences this condition. Symptoms can manifest as mood fluctuations or emotional lows. Unfortunately, these symptoms are often overlooked by patients themselves or misinterpreted by others as normal adjustments to the new role of motherhood. Consequently, timely assistance and support are frequently lacking. To address this, the investigators urgently need effective preventive measures for perinatal depression before it escalates. Recent research suggests that simple oral supplementation of vitamin B6 may help prevent and alleviate perinatal depression to some extent. Vitamin B6 plays several crucial roles in the body, including regulating neurotransmission and mental health. Therefore, it could contribute to maintaining emotional stability and psychological balance. In contemporary times, numerous screening methods for perinatal depression involve questionnaires. However, these methods presuppose an awareness of the possibility of perinatal depression. Individuals who are unaware of these questionnaires may go undetected. Hence, our aim is to investigate whether cardiac electrophysiology results obtained through a wearable device could offer a more objective evaluation of the status of perinatal depression. Our plan involves conducting a prospective study to delve deeper into the preventive and therapeutic effects of vitamin B6 on perinatal depression in pregnant women. Through systematic experiments and data analysis, the investigators aim to explore the impact of vitamin B6 dosage, duration, and timing of administration. Ultimately, the investigators hope to provide evidence-based recommendations and guidance for clinical practice. The investigators' goal is to offer new insights and methods to protect the mental health of expectant mothers, ensuring a pleasant and healthy pregnancy journey for each one.
Heart rate variability (HRV) is a measure of the variation in time between each heartbeat. It is an indirect and ubiquitous biomarker of performance readiness and recovery measured by most consumer-grade wearable fitness trackers. However, there is little documented on the relationship between HRV, training load, and performance measures in the Real-World. Whoop wrist-worn activity trackers have been validated against the gold-standard Electrocardiography (ECG) for HRV and HR measurements. Whoop leverages photoplethysmography (PPG) technology to continuously track (HR, HRV, respiratory rate, energy expenditure) and provides, daily, individual insights, trends, and coaching to improve strain, sleep, and recovery. Research has demonstrated that heart rate variability (HRV) guided training may be more optimal compared to predetermined training for aerobic exercise improvements. The purpose of this study is to assess the feasibility of providing personalized training recommendations based on HRV measured by a consumer-grade wearable (Whoop) in a real-world setting to better understand the HRV relationship with performance.
Extreme changes in the Antarctic environment can cause emotional and autonomic dysfunction. In this study, volunteers from the Antarctica stations in China provided scale scores and heart rate variability (HRV) data, which were used to assess the autonomic nervous system. Enroll twenty-two members from Zhongshan Station and the Great Wall Station who are overwintering. Using the Generalized Anxiety Disorder (GAD-7) scale, the Patient Health Questionnaire-9 (PHQ-9) scale, and the SF-36 quality of life scale to evaluate the individual's general physical and mental health. Analyze HRV and other associated parameters.
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.
