Filter by:The primary aims of this study are to determine the effect of percussive massage (30 min/session, 2 sessions/day, daily) during 10 days of unilateral limb immobilization on preserving muscle, vascular, and mitochondrial function. The following hypotheses will be tested: Hypothesis 1: Percussive massage will attenuate the loss of size, strength and endurance over the immobilization period compared to the control group, as measured by MRI, maximal isometric and isokinetic force production and muscle endurance test using Biodex dynamometry. Hypothesis 2: Percussive massage will attenuate the loss of vascular function and blood flow compared to the control group as measured by passive leg movement and femoral artery blood flow. Hypothesis 3: Percussive massage will attenuate the loss of skeletal muscle mitochondrial function and decrease H2O2 production during immobilization compared to the control group, as measured by high-resolution respirometry.
A long-term safety study in Brazilian patients with a confirmed diagnosis of Spinal Muscular Atrophy (SMA) treated with Onasemnogene Abeparvovec (Zolgensma®)
Skeletal muscle accounts for approximately 45-55% of total body mass in healthy adults and plays a pivotal role in whole-body metabolic health, locomotion and physical independence. Undesirable loss of skeletal muscle mass (atrophy) is, however, a common feature of many communicable and non-communicable diseases including ageing, bed-rest/immobilisation, cancer and physical inactivity. As such, the design of optimal strategies (e.g., different types of exercise) to "offset" these detrimental losses of muscle is a focus for both researchers and clinicians. One situation where losses of muscle mass occur very quickly (i.e., within a few days) is after surgery. However, at this time, most people (especially if they have had major abdominal or lower-limb surgery) are not able to perform exercise and as such a different strategy to maintain muscle mass needs to be found. It has been shown that electrical stimulation of the leg muscles can maintain muscle mass and function in patients after surgery. It is not however yet known, what the optimal electrical stimulation regime is to preserve muscle mass during situations of disuse. This study aims to examine the impact of three different electrical stimulation protocols on muscle building processes in individuals age-matched to those most commonly presenting for major abdominal surgery. This information will then be used in a clinical trial of surgical patients to see if it can preserve their muscle mass and function in the post-operative period.
Spinal Muscular Atrophy (SMA) is a rare neuromuscular condition, characterised by loss of motor neurons as a result of a mutation in the survival motor neuron gene. This results in muscle wasting and in the most common and severe type, death before 24 months. Over the recent years there has been a dynamic shift in the therapeutic options for these patients involving both approved therapies, including gene therapy, and access to clinical trials in genetic modifying. As a result of this mortality and morbidity have changed particularly for the SMA type 1 population and therefore there is now a changing phenotype with many children needing interventions at different time points compared to the natural history. This review process is a retrospective review from 1st July 2017 - 30th June 2022, when most of the new drug therapies were being introduced, of all the children aged from 0-16 years in the West Midlands region and their outcomes.
The goal of this observational study is to evaluate whether thigh muscle mass and muscle wasting are associated with mortality in patients who visit the emergency department. The main questions it aims to answer are: - Is thigh muscle mass associated with mortality in patient who visit the emergency department? - Does muscle wasting exist during staying in the emergency department? - Is muscle wasting associated with mortality in patient who visit the emergency department? Participants will be evaluated for serial thigh muscle mass using point-of-care ultrasound at the emergency department.
This is a data repository for multi-site multi-protocol clinic-based Natural History Study of ALS and Other Motor Neuron Disorders (MND). All people living with ALS or other MNDs who attend clinics at the Study hospitals (sites) are offered to participate in the Study. The Sites collect so-called Baseline information including demographics, disease history and diagnosis, family history, etc. At each visit, the Sites also collect multiple disease-specific outcome measures and events. The information is captured in NeuroBANK, a patient-centric clinical research platform. The Sites have an option to choose to collect data into 20+ additional forms capturing biomarkers and outcome measures. Captured data after its curation are anonymized (all personal identifiers and dates are being removed), and the anonymized dataset is shared with medical researchers via a non-exclusive revocable license.
The goal of this trial is to learn about how restricted sleep and not bearing weight on the leg affects muscle strength and posture control. Participants will walk exclusively on one leg, sleep at differing intervals, and complete posture tests, muscle strength tests, and muscle imaging. Researchers will compare adequate sleep and restricted sleep to see if muscle strength and posture are affected.
This study is investigating changes to the proteins in skeletal muscle that contribute to reduced muscle size and muscle function that occurs with aging.
The goal of this clinical trial is to compare two differential tourniquet pressure in lower extremity surgery cases. The main questions it aims to answer are: - What are the perioperative neurophysiological effects of ischemia and compression in the tissue under the tourniquet? - Are the effects of two different tourniquet pressures on neuromonitoring significantly different? - Can the ideal time of the reperfusion interval be evaluated by neuromonitoring? - Are the effects of two different tourniquet pressures on the quadriceps denervation significantly different from each other? Participants meeting the inclusion criteria will be evaluated for parameters to be used preoperatively. It will be evaluated in the 1st day, 1st week and 1-month follow-ups in the postoperative period. The investigators will compare two different tourniquet pressure ( Limb occlusion pressure +50 mmHg / + 100 mmHg) to see if it will be evaluated whether there is a significant difference in terms of quadriceps denervation, vas scores, total blood estimate volume loss, intraoperative MEP decrease, and recovery times, quadriceps tendon thickness, thigh circumfrences.
Intensive Care Unit Acquired Weakness (ICUAW) describes muscle weakness that occurs in around 40% of patients during an intensive care stay. The morbidity and mortality of these patients is significantly increased over a 5-year period. The aim of this study is to investigate the combined effect of early enteral high-protein nutrition and early muscle activation on muscle atrophy in critically ill patients. The study will include 40 patients (20 intervention, 20 observation) with requirement for enteral nutrition at time of inclusion. In the intervention group the maximum possible level of mobilization is carried out and muscles are activated twice a day using neuromuscular electrical stimulation (NMES). The nutrition plan of the intervention group is based on the applicable guidelines for intensive care medicine with exception of increased protein intake. The control group receives therapy without deviating from the standard according of the DGEM guideline. The study aims to show that the decrease in muscle mass is significantly less than in the control group (primary hypothesis) via ultrasound of the rectus femoris muscle and in case of given consent muscle biopsy. As secondary hypothesis it is examined whether the combination of early high protein intake and muscle activation improves muscle strength and endurance.
