SMART Exercise for PAD
Peripheral Arterial DiseaseAging3 moreSupervised exercise therapy (SET), consisting of treadmill exercise conducted three times weekly at a center while supervised by healthcare personnel, is first line therapy for people disabled by lower extremity peripheral artery disease (PAD). However, travelling three times/week to a center for SET is burdensome. Compared to SET, home-based exercise is more accessible and less burdensome. Yet, evidence-based guidelines recommend SET over home-based exercise for PAD. Walking exercise is first line therapy to improve walking distance for PAD, but it does not eliminate ischemic leg symptoms in most people with PAD. The investigators' work and that of others showed that nitrate-rich beetroot juice, which increases plasma nitrite, limb perfusion, and skeletal muscle function, significantly improved exercise tolerance and reduced non-response to exercise in people with and without PAD. The investigators will use a 2 x 2 factorial design to address two major barriers to achieving benefits from exercise therapy for PAD: First, guideline recommendations for supervised exercise therapy (SET) as first line therapy for PAD. Second, the inability of exercise therapy to eliminate PAD-related disability in most people with PAD. Participants will be randomized to one of four groups for 12 weeks: Supervised treadmill exercise + nitrate rich beetroot juice; supervised treadmill exercise + placebo, home-based walking exercise + nitrate rich beetroot juice, home-based walking exercise + placebo.
Telehealth Based Intervention to Improve Functional Capacity in Survivors of Childhood Cancer With...
Childhood CancerMobility LimitationThe 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.
Functional Fitness for Overweight or Obese Adults With Mobility Disabilities
Mobility LimitationOverweight or Obesity1 moreOver 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).
An INtervention TO Improve MOBility of Older Hospitalized Patients
Hospital MobilityMobility Limitation6 moreLow mobility during an acute care hospitalization is very frequent, particularly among older patients, and associated with adverse outcomes, such as persistent functional decline, institutionalization and death. However, increasing hospital mobility remains challenging because of the multiple existing barriers. The goal of this clinical trial is to test the effect of a multilevel intervention to increase hospital mobility, which addresses modifiable barriers and facilitators and does not require unavailable additional resources. This study aims to answer whether this intervention can improve mobility and patient-relevant outcomes such as life-space mobility and functional status. The multilevel intervention will target: The patients, who will receive an information booklet, a customizable diary, an exercise booklet and an iPad with access to the videos of the exercise booklet. The healthcare professionals (nursing staff and physicians) who will complete an e-learning, receive an oral presentation on the intervention, and receive a "mobility checklist" that reminds them of what they should assess daily regarding mobility. The hospital environment, where posters will be hung in the wards, including walking itineraries, on topics of interest to older adults. In a first phase, the intervention will be pilot-tested in one ward of each hospital. The intervention will then be adapted based on patient and healthcare professional feedback. In a second phase, the intervention will be tested in a cluster randomized controlled trial, and compared to standard of care.
Assessment of the Reliability and Validity of the Leg Lateral Reach Test in Adolescent Tennis Players...
Trunk InjuryMobility Limitation2 moreThe aim of this study is to evaluate the reliability and validity of the Leg Lateral Reach Test to measure thoraco-lumbo-pelvic segment mobility in adolescent tennis players. The fact that the test is valid and reliable for tennis players will contribute to monitoring trunk rotation flexibility in athletes, comparing them bilaterally, and revealing the exercise training necessary to improve performance.
Stepping-Up: Partnering With the Community to Prevent Early Mobility Decline
Mobility LimitationPreclinical mobility limitations (PCML) manifest early in the process of declining mobility, and are not typically identified or acted upon by clinicians. These mobility limitations manifest as changes in how daily tasks such as walking are performed (slower speed, lower endurance). Persons in the PCML stage are at increased risk for the onset of disability and chronic disease. Persistent deterioration in mobility is a predictor of mortality and has been reported even in the absence of changes in activities of daily living over a two-year period. Further, older persons with mobility limitations, including reduced gait speed, are at risk for falls. These cumulative transitions of a person's life-long mobility form their mobility trajectory and preventing mobility decline at an early stage along this trajectory is the focus of this research initiative. This study will evaluate a novel intervention, STEPPING-UP, for improving walking ability in persons with PCML.
HIFT for People With Mobility-Related Disabilities
Mobility LimitationPhysical DisabilityInvestigators will examine the feasibility and health outcomes following a high-intensity functional training intervention for people with mobility-related disabilities. In addition to participant recruitment, attritions rates, and satisfaction, investigators will assess changes to both physical health outcomes (e.g., strength, body composition) and psychosocial outcomes (e.g., quality of life). The findings will provide evidence for the efficacy of HIFT to improve various health outcomes for a population that experiences health disparities in access to, and engagement in, community-based exercise.
Minimizing Fall-Related Injury in Older Adults: a Motor Learning Approach
Fall InjuryFall Patients1 moreFalls are the leading cause of accidental injury and injury-related death among older adults. Despite evidence that falls can be prevented, fall related injuries have not declined over time. Current fall injury prevention techniques targeting mobility and bone strength have merit yet their effectiveness is limited. Indeed, a recent Patient Centered Outcomes Research Institute/National Institute on Aging funded pragmatic trial of individualized multifactorial strategy to prevent serious fall injuries in over 5500 seniors revealed no difference in fall injuries between the intervention and standard care arm. The inconclusive results of the investigation may be due in part to focusing on fall prevention rather than mitigation of fall-related impact acceleration and forces - the "fundamental variables" for injury prevention. A fall-related injury occurs when the body hits the ground with force that is greater than tissue strength. Development of innovative approaches that focus on fundamental variables of injury prevention is needed.
