Resistance exercise (RE) has been proposed as a possible strategy for prevention and rehabilitation of diseases. The increase in both muscle strength and the ability to perform tasks of day-to-day work environment and are well-characterized benefits of this type of training. The literature has been investigating the effectiveness of the RE for humans, yet few studies have been conducted with intellectual disabilities (ID). It is known that a sedentary lifestyle contributes to the development of cardiovascular disease, type 2 diabetes, hypertension, arthritis, and stress, depression, difficulty in socializing, stigma and discrimination. In particular, the ID is less active and is more likely to develop secondary diseases.
The additional effect of inspiratory muscle training as an adjunct to a general exercise training program in patients with COPD with inspiratory muscle weakness will be studied. The main hypothesis is that inspiratory muscle training combined with an exercise training program improves functional exercise capacity more than an exercise training program without the addition of an inspiratory muscle training program.
The investigators hypothesize that by applying a validated algorithm to accomplish early mobilization in surgical intensive care unit (ICU) patients, these patients will achieve a higher level of mobility which translates to shorter ICU length of stay and improved functional status at discharge. Additionally, the investigators hypothesize that genetic polymorphisms related to muscle strength and sleep will also explain some variance in these outcome variables.
The primary hypothesis for this study is that Myostatin and FHL-1 are important in the development of ICUAP and that changes in activity levels of muscle will modify the levels of expression and activity of these proteins.
The purpose of this study is to assess the effectiveness of a regular walking program (which inevitably involves human interaction) compared to a usual care condition and to a human interaction condition (without the extra walking program) in individuals residing in Long-Term Care (LTC). Outcomes of interest include: balance, strength, mobility, endurance, walking distance; rate and severity of falls; activities of daily living; mood and behaviour. It is hypothesized that participants taking part in the walking program will demonstrate maximal benefits compared to the no treatment control group (usual care) and the participants who will only receive social interaction. It is expected that benefits of the walking program will include decreased fall rates, and improved balance, endurance, strength, mood, behaviour, activities of daily living and quality of life indices. Given research findings that the addition of pleasant activities improves resident mood (Teri et al, 1997; 2003), it is expected that participants in the social interaction only group will demonstrate improvements in mood and other indices of quality of life.
The note re-introduces the external lid loading with the help of a lead weight for the temporary treatment of lagophthalmos. Although simple and effective, the technique is rarely used.Instead of wearing a monoculus, the patient uses an individually tailored lead weight (0.8 mm thickness, 1.0 -2.0 g) sticked on the lid, it enables its closure. A spontaneous ptosis indicates a too heavy weight. With the M. levator palpebrae intact, lid lifting is possible. The effect is gravity dependent, so that the patient has to wear the monoculus at night. To minimize the risk of lead intoxication, the surface of the weight is varnished. In case of a persistent paresis of the M. orbicularis oculi an internal lid loading can follow. A total of 152 lagophthalmos cases have been treated since 1997.All patients could close the lid immediately. Almost half of the patients had to re-adjust the weight several times per day due to hooded eyelids. The compliance was high, and a partial or complete restoration of the function of the M. orbicularis oculi occurred in 60% of the cases. In some subjects, the restoration of the M. orbicularis oculi was faster than of the M. orbicularis orbis. The external lid loading for the temporary treatment of lagophthalmos is simple and effective. Compared to a monoculus, the vision is unimpaired and the aesthetic is more appropriate for most patients. The faster restoration of the M. orbicularis oculi hints at a potentially facilitatory effect of the weight.
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 primary objective of this early-stage clinical study is to demonstrate an effect of single doses of CK-2017357 on measures of skeletal muscle function and fatigability in patients with generalized myasthenia gravis (MG).
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.
