Filter by:The investigators will determine if administration of HMB (hydroxymethylbutyrate) or EPA (eicosapentaenoic acid) will increase diaphragm and limb muscle strength for patients on breathing machines in an intensive care unit. The investigators will first measure the strength of the diaphragm and a limb muscle (the quadriceps)using magnetic stimulators to activate these muscles. Muscle size will be measured by using an ultrasound to measure diaphragm thickness and quadriceps thickness. The investigators will also perform a vastus lateralis muscle biopsy. Patients will then be randomized to receive either placebo (saline 30 ml every 12 hours via the GI tract, EPA (1000 mg given every 12 hours via the GI tract), HMB (1500 mg given every 12 hours via the GI tract), or the combination of EPA (1000 mg given every 12 hours via the GI tract) and HMB (1500 mg given every 12 hours via the GI tract). Drugs will be given for 10 days; at the end of this time (on day 11), strength measurements, ultrasound muscle size measurements, and the vastus lateralis biopsy will be repeated. On day 21 an additional followup set of diaphragm and quadriceps strength and size measurements will be made (the biopsy will not be repeated for this last set of measurements). Patients will be followed clinically and patient outcomes (mortality, duration of mechanical ventilation after study entry) will be recorded.
The study is designed to evaluate the safety and efficacy of using the L300 Plus as a neuroprosthesis device for walking in patients following an UMN injury or disease. The clinical study is proposed to determine the anticipated adverse event rate and treatment outcomes at the conclusion of the study.
The hypothesis is that a physical therapy intervention for foot and ankle of diabetic neuropathic individuals would affect positively the way they walk, lowering the harmful forces that these segments receive, that are associated mainly with lower range of movement, muscle weakness and loss of sensation. The participants will be randomly assigned into control group (regular treatment prescribed by their medical group) or into treatment group, that will receive 12 weeks of physical therapy intervention, twice a week, for 45 minutes each session. This will aim for increasing foot and ankle range of movement, muscle strength and improving sensory inputs.
Ankle dorsiflexor weakness (paresis) is one of the most frequently persisting consequences of stroke. The purpose of this exploratory study is to compare two different treatments -- Contralaterally Controlled Neuromuscular Electrical Stimulation (CCNMES) and Cyclic Neuromuscular Electrical Stimulation (cNMES) -- for improved recovery of ankle movement and better walking after stroke.
The purpose of this study is to evaluate the effect of coenzyme Q10 administration in improving mitochondrial function as measured by anaerobic threshold in older athletes on a stable dose of statin medication.
A double blind randomised placebo controlled parallel trial of the effect of fosinopril, an angiotensin converting enzyme inhibitor, on the quadriceps muscle in 80 COPD patients who have quadriceps weakness. Patients will have a baseline assessment including measures of quadriceps strength and endurance and a quadriceps biopsy. Patients with weakness will be randomised to ACE inhibitor or placebo and re-assessed after three months of treatment. The investigators aim to show that ACE-inhibition will alter the IGF-1/AKT/FoXO/atrogene pathways involved in muscle wasting in COPD.
Pathology - Generalized myasthenia gravis (MG) is cause of muscle weakness that can have a significant impact on daily life activity but can also be, when respiratory or bulbar muscles are involved, life-threatening. Rationale - Additionally to thymectomy, which indication of is still debated in absence of thymoma, the long-term treatment of generalized myasthenia gravis includes usually prednisone and azathioprine. However, the most used scheme for prescribing and tapering corticosteroid in MG resulted in a very important cumulative dose of prednisone. Indeed, at twelve month, more than 50 percent of patients are still daily treated with at least 18 mg of prednisone and the proportion of patients who are in remission and no longer taking prednisone is very low (Palace and NEWSOM Davis, Neurology 1998). Prolonged corticosteroid therapy is accompanied with various and major side effects, hypertension, osteoporosis, weight gain, glaucoma. Therefore, tapering, eventually discontinuing, prednisone earlier is a relevant therapeutic goal. For this reason, the investigators will compare to the standard one, a strategy consisting of a rapid decrease in corticosteroid. Objective - To assess whether, in patients with generalized MG requiring a long-term treatment with corticosteroids and azathioprine, that the strategy of rapid tapering allows discontinuing more rapidly the prednisone for equivalent efficacy than the classical strategy.
This is a study of the clinical and neuroimaging of general paresis. The investigators studied six patients with general paresis.
The aim of this research is to investigate critical illness neuromuscular abnormalities in neurocritical care patients.
An international consensual group recommends confirming the diagnosis of the Pompe disease after a dried blood spot (DBS) with a dosage of the enzymatic activity in other tissue. This strategy is currently used in the usual practice. The aim is evaluate the prevalence of the Pompe disease among patients with progressive limb girdle muscular weakness and/or axial deficiency, and/or respiratory insufficiency. The diagnosis will be confirmed using DBS.
