Filter by:Myasthenia gravis (MG) is an autoimmune disease caused by dysfunction at the neuromuscular junction, characterized by partial or generalized skeletal muscle weakness and fatigability. The estimated annual incidence rate of MG in China is 0.68/100,000, with a high rate of relapse and poor treatment compliance. This study is a prospective, observational, multi-center patient registry across China. To support standardized management and follow-up of MG patients in China, a Cloud-based MG Patient Management Platform (CN MG Base) was established in September 2023 with the support of the Chinese Rare Diseases Alliance. The platform aims to collect longitudinal clinical data including demographic information, age of onset, medical history, comorbidities, medication usage, treatment responses, and others. It is intended to collect newly registered MG cases each year and follow up with these patients at one-year intervals for ten years
Post-intensive care syndrome (PICS) encompasses persistent physical, cognitive, and psychiatric symptoms following ICU discharge, commonly triggered by serious conditions such as respiratory failure, sepsis, and mechanical ventilation. PICS prevalence is reported to be as high as 84% up to 12 months in patients with at least 2 days spent in the ICU or with mechanical ventilatory support. As a consequence, many patients do not return to they former level of function for weeks, months and even years. Muscular affection manifested by muscle weakness is particularly seen and is provoked by a combination of damage to the nerves or directly the muscles fibers. This affection is referred to as CU-Acquired Weakness (ICUAW). One third of the time, lower extremities are affected, often due to prolonged immobilization or sedation. Evidence suggests that early mobilization reduces the incidence of ICUAW at discharge and improves the number of patients able of stand. However achieving this early intervention is not always feasible due to time or personnel constraints. The purpose of the study is to examine the effectiveness of lower extremity neuromodulation for prevention of muscle deconditioning in patients admitted to the ICU.
In the United Kingdom, heart failure (HF) affects about 900,000 people with 60,000 new cases annually. Up to 60% of people living with HF also experience sarcopenia, known as loss of muscle mass and strength. Sarcopenia contributes significantly to low physical capacity and exercise intolerance and worsens the prognosis of the disease and quality of life. In comparison to primary sarcopenia (age-related sarcopenia), secondary sarcopenia occurs if other factors, including malignancy or organ failure, are evident in addition to aging. Secondary sarcopenia is highly common in patients with heart failure (Sarc-HF) (prevalence is 35%-69%), and has a significantly negative impact on exercise capacity, weight-adjusted peak maximal oxygen consumption, left ventricular function, and re-hospitalization rates and mortality. In this integrated study of NHS patients with HF, the investigators aim is to identify the underlying mechanisms of muscle weakness in HF utilizing including body composition, circulating metabolites (metabolic profile), and functional tests for (1) early detection of otherwise subclinical HF, (2) diagnostic assessment of clinically manifest HF-sarcopenia, (3) the risk stratification of subjects with a suspected or confirmed diagnosis, and (4) selection of an appropriate therapeutic intervention.
The perioperative preservation of functionality and quality of life plays an increasingly important role in older physically limited and frail patients undergoing cardiac surgery. Hereby, impairments of the skeletal muscle system integrity often contributes to a reduced physical performance. Early identification of these high-risk patients could help to initiate appropriate preventive and therapeutic measures. Volatile organic compounds (VOC) represent a non-invasive and real-time measurable approach for recording physiological and pathophysiological processes. Isoprene (2-methyl-1,3-butadiene) is one of the most abundantly exhaled VOCs and has recently been shown to originate from skeletal muscle metabolism. However, the prognostic value of isoprene as a volatile biomarker for skeletal muscle integrity, physical performance and functional outcome in patients undergoing cardiac surgery has not been evaluated before.
The goal of this clinical trial is to investigate of the effects of proprioceptive neuromuscular facilitation exercises on fatigue, muscle strength and functional parameters in patient with Myasthenia Gravis. The main questions it aims to answer are: - Do proprioceptive neuromuscular facilitation exercises reduce fatigue in patients with Myasthenia Gravis? - Do proprioceptive neuromuscular facilitation exercises increase muscle strength in patients with Myasthenia Gravis? - Do proprioceptive neuromuscular facilitation exercises improve functional parameters in patients with Myasthenia Gravis? - How well can patients with Myasthenia Gravis tolerate proprioceptive neuromuscular facilitation exercises? Participants will be divided into 2 groups as control group and exercise group with block randomization method. In this single-blind randomized controlled study, the participants in the control group will be placed on a waiting list without any intervention during the 6-week study period and at the end of the study, the interventions applied to the exercise group will be applied exactly the same. Proprioceptive neuromuscular facilitation exercises will be applied to the exercise group 3 days a week, 1 hour a day for 6 weeks. Individuals will be evaluated at the beginning and at the end of the study. Researchers will compare exercise and control group to see if there are effects of proprioceptive neuromuscular exercises patients with Myasthenia Gravis.
The aim of this prospective observational study is to investigate whether the presence or absence of directional preference impacts movement coordination impairments as measured in patients with Whiplash Associated Disorders (WAD). The primary research question this study aims to answer is: 1. Is the presence of directional preference in patients with WADs associated with more favorable improvements in the specific outcome measures as compared to those patients with WADs without the presence of directional preference. Patients in this study will asked to complete the following measures at baseline, during care, discharge, and 3 month follow up. 1. Numeric Pain Rating Scale (NPRS) 2. Optimal Screening for Prediction and Referral and Outcome-Yellow Flag (OSPRO-YF) 3. Neck Disability Index (NDI) 4. Craniocervical Flexion Test (CCFT) 5. Neck Flexor Endurance Test 6. Cervical Range of Motion Patients demonstrating a directional preference will be managed utilizing a Mechanical Diagnosis and Treatment approach (MDT) while those without directional preference will be managed according to published clinical practice guidelines for patients with Neck Pain and Movement Coordination Deficits (WADs).
The goal of this intervention study is to learn about how weight loss impacts molecular signaling of intermuscular adipose tissue (IMAT) in individuals with obesity. The main question it aims to answer is how inflammatory molecules secreted by IMAT promote muscle insulin resistance and inflammation, and how these same molecules are diminished after weight loss. Following screening visits involving body composition measures, blood testing, strength testing, and a thigh muscle biopsy, participants will go through a 12-week dietary intervention for weight loss. After 12 weeks, this will be followed by the same testing and biopsies that were completed before the intervention. Researchers will then compare outcomes of individuals who lost weight to individuals who did not lose weight.

The aim of the study is to compare the effect of Wii fit exercises and Pilates exercises on muscle strength and postural balance, and functional performance in adult patients with lower extremity burn.
During this pilot study, the investigators will examine the effects of whole-body electrical muscle stimulation exercise (WB-EMS Exercise) on neuromuscular junction (NMJ) transmission and fatigability in adults with Generalized Myasthenia Gravis (gMG). The investigators will also test whether a relationship exists between NMJ transmission dysfunction and fatigability in gMG, which has long been presumed but never directly assessed. Participants will undergo clinical and electrophysiologic testing before and after the WB-EMS Exercise intervention. The WB-EMS Exercise intervention will be delivered 2 times per week for 4 weeks. The hypotheses are (a) that the WB-EMS exercise will improve fatigability and NMJ transmission, and (b) that NMJ transmission dysfunction is related to fatigability.
