Filter by:A hallmark of aging is an impaired ability to adequately recover following a stressor, such as muscle disuse, resulting in muscle fibrosis and weakness thereby increasing the risk for falls and loss of independence. Mechanistic-based therapeutic strategies to enhance muscle recovery in older adults do not exist. Metformin has been implicated to have positive effects on muscle size and function through non-glycemic mechanisms. Metformin has been shown to enhance macrophage function and lessen cellular senescence burden by targeting SASP in a variety of muscle interstitial cells. However, the role of metformin to improve muscle recovery in older adults following disuse atrophy through immunomodulating and senomorphic mechanisms have not been examined. Therefore, the purpose of this study is to conduct a randomized, double blind, placebo-controlled clinical trial in older adult participants to determine if short-term metformin delivery (vs placebo) during the recovery phase following disuse atrophy can improve muscle regrowth.
This study is investigating changes to the proteins in skeletal muscle that contribute to reduced muscle size and muscle function that occurs with aging.
Patients admitted to the hospital often develop functional impairments due to being in bed most of the day. Each day of bedrest leads to significant muscle loss. As a result, many patients become dependent on others or require rehabilitation at a facility to improve mobility and function prior to returning home. Staff in the hospital is limited and often unable to mobilize patients every day while hospitalized. The investigators are testing a new experimental gamified physical therapy exercise software to see if it can be a fun, enjoyable way to help mobilize patients without the assistance of staff. The primary aim of this pilot/proof of concept study is to determine whether gamified physical therapy software can help inpatients exercise within the safety of their own beds and preserve pre-hospitalization function.
Low 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: 1. 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. 2. 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. 3. 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.
In this study, investigators aimed to investigate the morphometric parameters tenar muscles and joint configuration in patients with trapeziometacarpal osteoarthritis (TMC OA) osteoarthritis stages, thenar muscle parameters, radial subluxation rate, functional level and hand dexterity.
This study aims in investigating the effects of a core muscles' strengthening program on core muscles' atrophy and contraction ability. Twenty healthy adults recruited and randomly assigned to either a 5-week training group developed to activate and strengthen local trunk muscles or a control group. The training program includes isometric bridging exercises from various positions and dynamic exercises for lumbopelvic stability. Core muscles' thickness will be assessed at rest and contracting conditions, prior and after the intervention, using ultrasonography.
Inspiratory muscle weakness develops rapidly in ventilated critically ill patients and is associated with adverse outcome, including prolonged duration of mechanical ventilation and mortality. Surprisingly, the effects of critical illness on expiratory muscle function have not been studied. The main expiratory muscles are the abdominal wall muscles, including the external oblique (EO), internal oblique (IO) and transversus abdominis muscles (TRA). These muscles are activated when respiratory drive or load increases, which can be during e.g. exercise, diaphragm fatigue, increased airway resistance, or positive airway pressure ventilation. The abdominal wall muscles are also critical for protective reflexes, such as coughing. Reduced abdominal muscles strength may lead to decreased cough function and thus inadequate airway clearance. This will lead to secretion pooling in the lower airways, atelectasis, and ventilator associated pneumonia (VAP). Studies have shown that decreased cough function is a risk for weaning failure and (re)hospitalization for respiratory complications. Further, high mortality was found in patients with low peak expiratory flow. Considering the importance of a proper expiratory muscle function in critically ill patients, it is surprising that the prevalence, causes, and functional impact of changes in expiratory abdominal muscles thickness during mechanical ventilation (MV) for critically ill patients are still unknown. Ultrasound is increasingly used in the ICU for the visualization of respiratory muscles. In a recent pilot study the investigators confirmed the feasibility and reliability of using of ultrasound to evaluate both diaphragm and expiratory abdominal muscle thickness in ventilated critically ill patients (manuscript in preparation). Accordingly, the primary aim of the present study is to evaluate the evolution of abdominal expiratory muscle thickness during MV in adult critically ill patients, using ultrasound data.
Patients surviving critical illness experience significant skeletal muscle dysfunction and weakness. Muscle atrophy suffered during critical illness has a long-term impact on the functionality and mobility of these individuals. As a result, individuals surviving critical illness have a significant reduction in quality of life, even up to 5 years post discharge. Research including large randomized controls demonstrates that rehabilitation focused on active mobilization may positively influence patient outcomes. Thus, early mobilization is an important intervention that has many purported benefits. Current rehabilitation practice in the intensive care unit (ICU) and recommendations from clinical practice guidelines such as the Society of Critical Care Medicine, PADIS Guidelines support these interventions to reduce the detrimental effects of immobilization during critical illness. Early mobilization is routinely thought of as standard of care for patients admitted for acute respiratory distress syndrome and sepsis. However, a significant number of recent randomized controlled trials implementing early rehabilitation and mobilization interventions fail to demonstrate immediate or long-term benefits.10,11,18,19 Interesting, active mobilization and rehabilitation analyzed in systematic review had no impact on mortality and "no consistent effects of function, quality of life and ICU or hospital length of stay."18 There are a few potential explanations for interventions not leading to reduction in impairment or functional benefit. Scientific Premise: From our preliminary data (Figure 1) and my clinical experience, a significant cause of the physical impairments in these patients is reductions in muscular power. Muscular power is a critical determinant of functional mobility.20 Preliminary data demonstrate that lower extremity muscle power is significantly reduced in this population and furthermore, these deficits are strongly correlated to physical function. Muscle power training is a potential therapeutic intervention that could lead to more robust improvements in physical function. This concept has been explored extensively in community-dwelling older adults. A recent systematic review of controlled trials demonstrates that power training is superior to traditional resistance training at improving functional performance when comparing the two training modalities.21 Furthermore, power training is feasible for older adults and clinical populations of Parkinson's Disease, Stroke, and frailty.22-27 Thus the feasibility and pragmatic nature of power training is not a concern. Of interest, a randomized controlled trial was completed in institutionalized frail nonagenarians (>85 years or older).27 In this study, no patients drop-out of study due to power training and significant benefits in function were achieved.27 Therefore, the investigators propose a interventional trial to study the effect of a standardized muscle power training program for patients admitted to the ICU for critical illness.
This is a phase 1b investigator-initiated clinical trial that will evaluate the safety and feasibility of E-CEL UVEC® cells with the aim of improving outcomes for patients with full-thickness rotator cuff tears who undergo arthroscopic surgical repair. Allogeneic E-CEL UVEC cells will be delivered to the tendon repair site and to the muscle adjacent to the tendon repair site.
When a person is put on a breathing machine the investigators think that the breathing muscles can get weaker. The investigators are not sure how quickly this happens but in some people this leads to problems when they try to breathe on their own without the breathing machine. The diaphragm is at the bottom of a person's chest separating their lungs from what is in their belly and it is a very strong muscle. In fact, it is main muscle that one uses for breathing. An ultrasound machine is a painless way to see what is happening beneath the skin. It is safe and easy to do. Using an ultrasound the investigators are planning to measure how thick the diaphragm is and how much it changes while a person is on a breathing machine in the ICU. Getting a better understanding of this condition could lead to improved treatments that might help support patients who require a ventilator for breathing. The investigators hypothesis is that patients for whom the breathing machine is doing all of the work of breathing, will have their diaphragm thickness gradually decrease and changing to a breathing modem mode where they have to put in more effort the diaphragm thickness will start increasing again.
