Active clinical trials for "Muscle Weakness"

Multiple Sclerosis (MS) patients with subjective dysphagia will be tested for tongue strength fatigue using a strictly defined fatigue paradigm. A maximum of 40 sets will be performed, each set consisting of 5 repetitions of 80% of maximum isometric pressure (MIP) at the anterior tongue, followed by a MIP at the anterior tongue. Cut-off criteria are a MIP <50% of the baseline MIP, pronounced subjective discomfort and/or exceeding the allocated test time of 30 minutes.

The aim of this research is to investigate critical illness neuromuscular abnormalities in neurocritical care patients.

Muscles atrophy and weakness are common in intensive care units, their origin is multifactorial. Passive then active mobilization with cyclo-ergometer have shown to improve functional abilities and limit muscle weakness among intensive care unit patients. Electrical muscle stimulation should limit the atrophy and muscle weakness in intensive care unit associated with early mobilization. This study aims to compare the association early cyclo-ergometer mobilization with electrical muscle stimulation versus cyclo-ergometer mobilization only to prevent muscle atrophy and weakness in intensive care unit.

Patients requiring prolonged time on the ventilator are susceptible to a wide range of clinical complications and excess mortality. It is therefore imperative for them to wean at the earliest possible time. Respiratory muscle weakness due to disuse of these muscles is a major underlying factor for weaning failure. Surprisingly, there is not much known about the impact of critical illness and MV on the expiratory abdominal wall muscles.These muscles are immediately activated as ventilation demands increase and are important in supporting respiratory function in patients with diaphragm weakness. Weakness of expiratory abdominal wall muscles will result in a decreased cough function and reduced ventilatory capacity. These are considerable causes of weaning failure and (re)hospitalisation for respiratory complications such as pneumonia. Recent evidence shows that neuromuscular electrical stimulation (NMES) can be used as a safe therapy to maintain skeletal muscle function in critically ill patients. This study will be the first to test the hypothesis that breath-synchronized NMES of the abdominal wall muscles can prevent expiratory muscle atrophy during the acute stages of MV.

The lateral neck flexor endurance test has been proposed to assess for unilateral muscular deficits. It is not known if individuals with hyperlaxity have different muscular endurance than individuals without hyperlaxity.

The aim of this study is to examine the prevalence of lower urinary tract symptoms (LUTS) in children with Duchenne Muscular Dystrophy (DMD) and the relationship between functional level, posture, muscle strength, pelvic floor muscle control, participation in activities of daily living, and quality of life that may be associated with these symptoms. Forty-five children with DMD between the ages of 5-18 (Age: 9.00±3.32 years, Weight: 31,10±12,59 kg, Height: 125,87±18,46 cm) and their families were included in the study. LUTS was assessed with Dysfunctional Voiding And Incontinence Scoring System, functional level with Brooke Upper Extremity Functional Classification and Vignos Scale, posture with the New York Posture Assessment Questionnaire, Baseline Bubble Inclinometer (10602, Fabrication Enterprises Inc. New York, USA) and Baseline Digital Inclinometer (12-1057, Fabrication Enterprises Inc, New York, USA), participation in activities of daily living was assessed with the Barthel Index and quality of life was assessed with the Pediatric Quality of Life Inventory 3.0 Neuromuscular Module. Also, using the Hoggan microFET2 (Hoggan Scientific, LLC, Salt Lake City UT, USA) device, hip flexors, quadriceps femoris muscles, shoulder flexors, elbow extensors, elbow flexors, trunk extensors and flexors were evaluated in terms of muscle strength. Evaluations were made once, and the associated factors were compared in the group with and without LUTS, and the relationship between the factors and the severity of LUTS was examined.

A few recent observational studies show that despite the lack of clear recommendations, many individuals with myasthenia participate in exercise. However, no link has been found between exercise and the severity of myasthenia symptoms, measured by the Muscle Myasthenia Score or the Myasthenia Gravis Composite Score. This suggests that there are other factors that may limit or prevent some individuals from being active, or factors which may facilitate participation in exercise. Studies in other diseases have shown that there are internal (beliefs, motivation, etc.) and external (cost, accessibility, etc.) factors unrelated to the disease which may play a role in exercise participation. The aim of this study is to identify factors that facilitate or limit exercise in individuals with autoimmune myasthenia gravis, congenital myasthenia syndrome and Lambert-Eaton syndrome.

This is a study during which the investigators collect plasma and cells from patients with myasthenia gravis for the purpose of finding new antibodies.

Lambert-Eaton Myasthenic Syndrome (LEMS) is a rare autoimmune disorder which affects the nerve-muscle junction. The major symptoms of LEMS are progressive muscle weakness. Many patients experience other symptoms like dry mouth or impotence. Congenital Myasthenia (CM) is an inherited disorder with similar affects and symptoms. 3,4-Diaminopyridine (DAP) is an experimental drug that has improved strength in some subjects with (LEMS). There are no other accepted treatments for LEMS and DAP has relatively few side effects.

Myasthenia gravis (MG) is an autoimmune disease that is characterized by muscle weakness and fatigue. The role of the thymus in MG has been suggested by the evidence that 10% to 15% of patients present with a thymoma and at least 60% with thymus hyperplasia or dysplasia.Beneficial effects of thymectomy in patients with MG have been described in 40% to 90%.Few studies have looked at the incidence of reintubation (not just within 24 hours after extubation), the factors associated with reintubation, and patient outcome. Premature extubation may lead to hypercarbia, hypoxemia, pulmonary hypertension, right heart failure, and myocardial ischemia. Additionally, it subjects the patient to the physical risks of reintubation, including esophageal intubation, laryngeal trauma, and pulmonary aspiration. The purpose of the present study was to determine the incidence of reintubation, the variables associated with reintubation, and patient outcome
