27 Clinical Trials for Various Conditions
People aging with HIV are at higher risk for Alzheimer's disease and related dementias, and although physical activity is a promising target to mitigate such risk, this population engages in low levels of physical activity. Few studies have tested cognitive effects of exercise interventions or examined mechanisms of adherence to long-term exercise among diverse samples of midlife and older people with HIV. The current study will leverage an existing R01 to address these gaps and provide implications for development of personalized approaches for the treatment and prevention of cognitive impairment and dementia in older people with HIV.
The purpose of this study is to assess the effects of tDCS in combination with TUS for the treatment of pain and functional limitations in subjects with NSCLBP. The investigators hypothesize that there will be a decrease in pain levels with active stimulation, when compared to sham stimulation.
The purpose of this research study is to evaluate the effects of combining physical exercise with a resveratrol supplementation on the physical function of older adults.
This is a randomized, controlled, pilot study of two separate Cohorts of patients from the intensive care unit. Cohort I will enroll 50 patients and randomize to receive one physical therapy session per day or receive usual ICU care. Cohort II, will enroll an additional 50 patients and randomize to receive either two physical therapy sessions per day or usual care. Outcome will be length of hospital stay measured in days. Secondary outcomes will be mortality, ventilator days, ICU days, and for Cohort II, grip strength, dynamometer strength assessments and the short physical performance battery (SPPB). Study subjects will have blood for cytokine analysis through their first week of study.
The purpose of this study is to test the effectiveness of a DVD-delivered, home-based, six-month physical activity intervention for older adults. A comparative effectiveness study of the FlexToBa DVD exercise program will be conducted in 2014.

The work will evaluate the metabolic costs for daily activities across the lifespan and evaluate the influence of having functional impairments.
This study is investigating the effects of a home-based resistance exercise program, administered via an interactive telecommunications system, in functionally limited older veterans.
Approximately 45% of older adults in the U.S. have 2 or more chronic health conditions (e.g., arthritis, hypertension, diabetes) in addition to functional limitations that prevent performance of health self-management activities. Self-management continues to be the gold standard for managing MCC, but functional limitations create difficulty with these activities (e.g., physical activity, symptom monitoring). Restricted self-management accelerates the downward spiral of disability and accumulating chronic conditions which, in turn, increases rates of institutionalization and death by 5-fold. Currently, there are no tested interventions designed to improve independence in health self-management activities in older adults with MCC and functional limitations. Research suggests that older adults are more likely to change behavior with interventions that assist with planning health-promoting daily activities, especially when contending with complex medical regimens and functional limitations. Combined with occupational therapy (OT), behavioral activation (BA) shows promise to improve health self-management in populations with chronic conditions and/or functional limitations. This innovative combination uses the goal setting, scheduling/monitoring activities, and problem-solving components of the BA approach as well as the environmental modification, activity adaptation, and focus on daily routines from OT practice. The investigators will test the effect of this combined approach in a Stage I, randomized controlled pilot feasibility study compared to enhanced usual care. The investigators will recruit 40 older adults with MCC and functional limitation and randomize 20 to the PI- delivered BA-OT protocol. This research will inform modification and larger-scale testing of this novel intervention and provide data for a federally funded career development award.
The overall purpose of this study is to investigate whether pulmonary limitations that increase the oxygen (O2) cost of breathing impact dyspnea on exertion (DOE) and peak exercise capacity in patients with HFpEF and obesity. As per investigator's hypothesis, obesity is likely a significant contributor to DOE and exercise intolerance in patients with HFpEF.
In this study, we will randomly assign 360 older adults to 12 months of 5 minutes per day of functional resistance training or to a delayed treatment control condition, and measure the impact of the training on measures of lower extremity performance and walking ability.
Over 64 million people in the U.S. have a permanent disability, with mobility-related disability (MRD) representing the most prevalent disability type (13.7%). Adults with MRD are 66% more likely to be overweight or obese than their non-disabled peers. Exercise in adults with MRD is important for weight management and is associated with improvements in obesity-related health conditions including hypertension, hyperlipidemia, insulin processing/sensitivity, etc. However, over half (57%) of adults with MRD do not exercise, while 22% engage in exercise of insufficient duration or intensity to obtain health benefits. Adults with MRD face numerous barriers to participation in community-based exercise, and exercise is frequently limited to short-term referrals for outpatient physical and/or occupational therapy. High-intensity functional training (HIFT) represents a potentially effective strategy for community-based exercise to support body weight and obesity-related health conditions, in addition to improving physical function and aspects of psychosocial health for people with disabilities. Preliminary evidence supports the effectiveness of HIFT to improve body composition, cardiovascular and muscular fitness, insulin processing and insulin sensitivity in non-disabled adults who are overweight/obese. To date, no study has systematically evaluated the feasibility or effectiveness of a community-based HIFT intervention for improving obesity-related health outcomes in overweight/obese adults with MRD. Thus, the proposed study will implement a 6-mo. pilot trial to evaluate the feasibility and potential effectiveness of a HIFT intervention (60 min sessions/3 days/wk.) in 25 adults with MRD and overweight/obesity. This study will address the following aims: Aim 1: Evaluate the intervention feasibility based on participant recruitment, session attendance, retention, outcome assessment completion, and the results of semi-structured exit interviews to obtain information regarding experience and overall satisfaction with the intervention. Aim 2: Evaluate changes (baseline - 6 mos.) in weight and fat-mass/fat-free mass, and components of the metabolic syndrome (waist circumference, blood pressure, HDL-cholesterol, triglycerides, fasting glucose).
Declines in cognitive function and walking function are highly intertwined in older adults. A therapeutic approach that combines complex (cognitively engaging) aerobic walking exercise with non-invasive electrical brain stimulation may be effective at restoring lost function. This study tests whether electrical stimulation of prefrontal brain regions is more beneficial than sham stimulation.
The participants are asked to take part in this clinical trial, a type of research study. The participants are SJLIFE study participants and may have a hard time exercising (exercise intolerance) due to side effects of cancer treatment received as a child.This study is being done to determine if a personalized exercise plan will help childhood cancer survivors who have exercise intolerance become more active. Primary Objectives: To achieve the goal of this study, we propose the following three Objectives: Primary Objective 1: To determine the efficacy of an individually tailored, home-delivered aerobic and strengthening intervention to improve exercise capacity in survivors of childhood cancer with exercise intolerance (peak oxygen uptake (peak VO2) \<85% of age and sex predicted). Primary Objective 2: To determine the effects of an individually tailored, home-delivered aerobic and strengthening intervention on measures of cardiac, pulmonary, musculoskeletal, and neurosensory function in survivors of childhood cancer with exercise intolerance. Primary Objective 3: To determine the effects of an individually tailored, home-delivered aerobic and strengthening intervention on emotional health, participation in family and community activities, quality of life, and cognitive function in survivors of childhood cancer with exercise intolerance.
This is a multi-site, randomized, single-blind (researchers), active treatment concurrent control trial with individuals aged 50-80 living with HIV who experience fatigue and live a sedentary lifestyle. The overall goals of this proposal are to determine whether high-intensity interval training (HIIT) can overcome physical function impairments and increased fatigue (Aim 1) and impairments in mitochondrial bioenergetics of older people with HIV (PWH) to a greater extent than continuous moderate-intensity exercise (CME) (Aim 2). The investigators further seek to determine whether a biobehavioral coaching intervention following either HIIT or CME can promote long-term adherence to physical activity (Aim 3), a crucial component of the sustainability of the intervention. This study will enroll 100 participants in Aurora, Colorado and Seattle, Washington. Data collection will occur at each visit, with baseline data collected at the initial visit. A 3-month follow-up will be conducted over the phone from the date of the final visit. The initial enrollment goal of 100 was increased to 120 in 2023 to facilitate a larger number of participants with key secondary outcomes.
This study is being conducted to test if a program with physical activity and learning about movement (including goal setting, benefits of physical activity, and how to increase physical activity gradually) helps people to become more active and to move better. The physical activity program involves specific exercises done in a group setting, and the education part will involve learning about different ways to move to make everyday activities easier. The program will last 16 weeks. This program will take place in a large fellowship area of a partner church through an established community-based participatory research partnership in Chicago, IL.
Shoulder slings are commonly worn after shoulder surgery. In geriatric patients, painstaking care is taken to reduce any factors that may increase the chance of experiencing a fall. Currently, it is not understood if wearing a sling affects someone's general gait and balance.
This research study is looking to compare the effects of two uniquely different power training interventions (high force, lower velocity versus low force, high velocity) on changes in mobility status among older individuals at risk for mobility disability.
The purpose of this study is to evaluate the site and mechanisms responsible for expiratory airflow limitation in chronic, treated, non-smoking, stable asthmatics with moderate to severe persistent expiratory airflow obstruction. Treatment will include inhaled corticosteroids and long acting beta2agonists. The investigators are interested in determining whether the large and/or small airways are the predominant site of airflow limitation. The investigators are also interested in determining whether intrinsic small airways obstruction and/or loss of lung elastic recoil is responsible for expiratory airflow limitation. The investigators are also interested to evaluate the role of varying doses of inhaled corticosteroids to suppress large and small airway inflammation using exhaled nitric oxide as surrogate markers of inflammation. For comparison purposes, spirometry and measurements of exhaled nitric oxide will also be obtained if possible during a naturally occurring exacerbation of asthma.
The purpose of this study is to evaluate the site and mechanisms responsible for expiratory airflow limitation in chronic, treated, non-smoking, stable asthmatics with moderate to severe persistent expiratory airflow obstruction. Treatment will include inhaled corticosteroids and long acting beta2agonists and long acting muscarinic antagonists. We are interested in determining whether the large and/or small airways are the predominant site of airflow limitation. We are also interested in determining whether intrinsic small airways obstruction and/or loss of lung elastic recoil is responsible for expiratory airflow limitation and to what extent may be attributed to loss of lung elastic recoil vs decreased airway conductance in peripheral airways. We are also interested to evaluate the role of varying doses of inhaled corticosteroids to suppress large and small airway inflammation using exhaled nitric oxide as surrogate markers of inflammation. For comparison purposes, spirometry and measurements of exhaled nitric oxide will also be obtained if possible during a naturally occurring exacerbation of asthma. High resolution thin section CT of the lung will also be obtained. Analysis will evaluate integrity of the lung parenchyma as to absence and or presence of emphysema and extent of emphysema using voxel quantification. We will also investigate optical coherence tomography to detect clinically unsuspected emphysema. We will also obtain autopsy material when available in asthmatics who expire. Will also measure serum periostin as a marker of inflammation by collaborating with Genetech in San Francisco.
The purpose of this study is to determine whether a 12-month physical activity counseling program, compared to usual care, improves physical performance in a sample of older veterans. The primary physical performance outcome is change in gait speed.
The proposed clinical trial is aimed at demonstrating the important role wheelchairs play in preventing pressure ulcers (bed sores). Although most pressure ulcers can be prevented, they are common in nursing home settings because their causes are difficult to identify. This clinical trial will guide practitioners toward improving preventive care practices by demonstrating how to effectively apply wheelchair and seat cushion technology.
