49 Clinical Trials for Various Conditions
The objective of this study is to find a more objective and accurate way to assess the efficacy of the treatment for neurogenic orthostatic hypotension. For this purpose, the investigators will use an activity monitor to determine the amount of time patients spend in the upright position (standing and walking; upright time) during 1 week of placebo (a pill with no active ingredients) and 1 week of their regular medication for orthostatic hypotension (midodrine or atomoxetine at their usual doses). Total upright time (i.e. tolerance to standing and walking) will be compared between placebo and active treatment to test the hypothesis that it can be used to assess the efficacy of the treatment for orthostatic hypotension and whether this outcome is superior to the assessment of symptoms using validated questionnaires.
Dr. Jonathan Hsu and Dr. Eric Adler are conducting a research study to find out more about how implantable cardiac defibrillator (ICD) settings can be adjusted to improve patient cardiovascular health and quality of life. Patients are being asked to participate in this study if they have a history of heart failure and have or are scheduled to be implanted with a BIOTRONIK ICD that is capable of closed loop stimulation (CLS). CLS is a device setting that works with the cardiovascular system to optimize their heart rate during physical activity. This study is comparing BIOTRONIK's CLS setting to a standard accelerometer setting, which also is able to adjust the heart rate by movement sensors, when necessary. This study has been initiated by Dr. Hsu and Dr. Adler and is financially supported by BIOTRONIK, Inc. There will be approximately 15 participants in this trial.
Maintenance of analgesia during a patient stay in the hospital has been an important area of investigation after demonstrating a direct correlation between level of sedation and mortality in the ICU setting.

The primary objective of this protocol is to test whether an activity monitor with an online motivational rewards component will increase physical activity levels of middle school-aged students. The secondary objective is to learn about the functionality and utilization of the activity meter device among this age group.
Manually suspending an insulin pump at the beginning of aerobic exercise reduces the risk of exercise-associated hypoglycemia (low blood sugar) in patients with type 1 diabetes (T1D). However, since patients with T1D often do not make exercise-related adjustments to their insulin regimen, our group has developed an algorithm to initiate pump suspension in a user-independent manner upon projecting exercise-associated hypoglycemia. The current study seeks to test the efficacy of this algorithm by asking users to participate in a sports camp while wearing an insulin pump, continuous glucose monitor, and accelerometer/heart rate monitor (to detect exercise), which will communicate electronically to a pump shutoff algorithm. On one of the days the algorithm will be used, while on the other day their normal insulin rate will continue for comparative purposes. The investigators hypothesize that the use of an accelerometer-augmented computer algorithm for insulin pump suspension during exercise will result in significantly fewer episodes of hypoglycemia (both during exercise and in post-exercise monitoring) than in exercise without a pump suspension algorithm.

This study will assess whether a movement detecting wristwatch can accurately detect seizures and seizure characteristics and record them into an online epilepsy diary. The patients may manually record a description into the online epilepsy diary of the symptoms they experienced before, during or after the seizure.
Some patients' heart rates do not increase as needed during activities and exercise, which can make them feel tired and fatigued easily. The patients in this study have a pacemaker with a FDA approved rate response sensor, which senses activity level by sensing motion (through a component known as an accelerometer) and/or breathing changes (known as minute ventilation). These changes in motion or breathing make the pacemaker increase the patient's heart rate. This study is being conducted to see which rate response sensor is better (motion driven or breathing driven). The study is also investigating whether optimizing the sensor based on the individual patient will give better results in terms of increasing the patient's exercise capacity. The hypothesis is that rate responsive pacing driven by the minute ventilation sensor results in improved functional capacity compared to accelerometer in chronotropically incompetent patients.
Background: * Good measures of physical activity are needed for studies correlating physical activity and the risk of developing certain diseases. * In preparation for use in a study of diseases and risk factors in Hispanic populations, NCI is evaluating a new model accelerometer to measure physical activity. An accelerometer is a small device worn on a belt at the waist that measures and records movement, capturing movement intensity and duration and associating it with clock-time. * The new accelerometer (ActiGraph GTIM) uses a different type of motion detector from that used in the previous model (ActiGraph 7164). Objective: To evaluate and compare the ActiGraph GTIM with the ActiGraph 7164 by collecting physical activity data using both models. Eligibility: Men and women 18-74 years of age. Design: Study participants wear both model accelerometers while they walk or jog around a track at several self-selected paces. Data from the two devices are compared.
The Physical Activity Self-efficacy (PAS) intervention is a web-based behavioral intervention newly developed to promote physical activity in adults with obesity. The conceptual framework for the PAS intervention is based on self-efficacy theory. The objective of this study is to investigate the feasibility and acceptability of implementing the PAS online intervention for adults with obesity recruited from a local weight management center in the United States of America (USA). The study design is a prospective, double-blind, parallel group randomized pilot trial. Thirty participants will be randomly assigned to the PAS group or usual care group to achieve a 1:1 group assignment. Recruitment of participants is scheduled to begin in January 2024 or earlier at a local weight management center within a private healthcare system in the USA. There are five eligibility criteria for participation in this study (e.g., a body mass index ≥ 25.00 kg/m2). Eligibility verification and data collection will be conducted online. Three waves of data collection will take up to 14 weeks depending on participants' progress in the study. Instruments designed to measure demographic information, anthropometric characteristics, self-efficacy, and acceptability will be included in the survey battery. A research-grade accelerometer will be used to measure free-living physical activity objectively. Data will be analyzed using descriptive statistics and inferential statistical models under an intention-to-treat approach. This study will be sponsored by the Transdisciplinary Areas of Excellence Seed Grant Program from Binghamton University.

Children undergoing polysomnography, the gold standard for assessing sleep quality and duration, at Arkansas Children's Hospital may be eligible to participate. Participants will be asked to wear sleep trackers on the day of their sleep test. The data collected from the sleep trackers will be compared with the polysomnography results to determine the devices' accuracy.
The goal of this clinical trial is to learn if a brief health coaching intervention based on an approach known as brief action planning + Fitbit can increase physical activity in employees with chronic knee symptoms who work for Advocate Aurora Health. The main questions it aims to answer are: * Will a greater proportion of people in the health coaching intervention increase physical activity to at least 150 minutes of moderate-to-vigorous physical activity per week than a group of people with an attention-control intervention (Fitbit+health education coaching)? * Can we predict who will not increase physical activity levels to at least 150 minutes of moderate-to-vigorous physical activity per week by the end of the study (3 and 6 months) based upon Fitbit data captured over the first four weeks? Researchers will compare a health education coaching intervention + Fitbit to see if providing a Fitbit + attention control will increase physical activity to at least 150 minutes of moderate-to-vigorous physical activity per week among members of the attention-control group. Participants will engage in * Online study orientation and question and answer session * Three assessment sessions (baseline, 3 months, 6 months) * A 12 week intervention with no less than four (4) and no more than twelve (12) health coaching sessions. Physical activity health coaching will make action plans for health coaching. Health education coaching will focus on educating participants on non-physical activity factors related to a comprehensive management of chronic knee symptoms, such as managing fatigue, sleep hygiene, mindfulness, etc.

The objective of the study is to evaluate whether gait-cadence, as measured from a patient's mobile device at-home, can provide an accurate assessment of a patient's functional status prior to major abdominal surgery and identify patients at risk of poor functional outcomes.
The purpose of this research is to learn about how to promote physical activity among adolescent girls by testing the feasibility and initial effectiveness of the Girls Can...Move! intervention. Girls Can...Move! will target each component of physical literacy by providing opportunities for adolescent girls to gain knowledge about their own physical activity level, to explore and practice different types of physical activities, and to learn from active female role models. Female participants (n = 30) from one middle school will be randomly assigned to the Girls Can...Move! intervention group or a control group at a 1:1 ratio. The primary outcome variables, physical activity and physical literacy, will be assessed before and after the 8-week Girls Can...Move! intervention using accelerometers and online surveys.
Adolescent's poor sleep habits have been linked to adverse outcomes. Recent advances in activity tracking have provided researchers with cost-effective and non-invasive measurements of sleep in a free-living environment. The primary objective is to determine the mean differences in Fitbit accelerometer sleep quantity (mins) between High School student-athletes and non-athletes during a competitive academic semester over continuous monitoring for two weeks.
Heart Failure (HF) is a highly prevalent disease that also carries high morbidity and mortality. The Food and Drug Administration (FDA) recognizes the importance of developing patient-centric endpoints that are relevant to patients beyond mortality and hospitalizations. Although functional status can be objectively measured by peak exercise oxygen consumption, it is difficult and impractical to implement in large clinical studies, especially in an ambulatory real-world setting. Recently, new mobile health technologies have emerged as clinical tools and offer an opportunity to overcome these challenges in measuring functional capacity and recording symptoms. The goal of this observational study is to evaluate the feasibility of monitoring functional capacity among patients with heart failure (HF) using mobile health monitoring platforms. Everion® and Apple Watch Series 4 and above will be used for this study. The BiovitalsHF® mobile app can capture patients' key cardiopulmonary physiological parameters, functional capacity (using activity patterns, including guided mobile-based 6MWT, audio recording) and assessment of QoL through validated PROs.
The investigators plan to use smartphone and wearable sensor technology to characterize the activity patterns of participants with peripheral artery disease (PAD) (n=24) participating in a 12-week supervised exercise training (SET) program, and incorporate the resulting data into a web-based dashboard for participants and study staff.
The purpose of this study is to determine the validity of the Human Activity Profile and Godin self-report questionnaires of physical activity in persons seeking metabolic surgery.

Total Knee Arthroplasty is becoming an increasingly common operation. An important part of a successful overall patient outcome is regaining functional range of motion after surgery. Wearable devices for fitness have become increasingly common. This study seeks to utilize wearable technology to enhance the post-operative rehabilitation experience by allowing patients and surgeons to monitor patient recovery in real time. The Consensus TracPatch is a wearable device which utilizes an accelerometer, temperature sensor and step count to monitor patient recovery. This tool provides critical, real-time information that may offer a more complete source of data to understand a patient's postoperative clinical and rehabilitation course and guide physician postoperative management. The study hypothesizes that this new technology will improve patient postoperative mobility and patient-physician communication.
