Filter by:Spinal muscular atrophy (SMA) are one of the common physical disabilities in childhood. For SMA, progressive muscle weakness and early fatigue hamper the mobility of the sufferers. Osteopenia is common for this population group due to poor bone growth and muscle disuse. As a result, non-traumatic related fractures and bone pain are common. Recently, whole body vibration therapy (WBVT) has been proven to improve bone health and muscle function in healthy adults and post-menopausal women. Among the limited studies on the WBVT for children with muscular dystrophies, promising results have been shown on gross motor function, balance, and muscle strength and the WBVT appears to be safe for children with SMA. The present pilot study is designed to investigate if WBVT is safe and feasible for individuals with SMA and if WBVT can improve muscle function, functional abilities, postural control and bone mineral density in children with SMA. Convenience samples of 10 individuals with SMA type III will be recruited. The participants will receive the WBVT of 25 Hertz and a peak-to-peak amplitude of 4mm for a session of about 18 minutes, 3 days per week for 4 weeks. Assessment will be performed at the baseline and the completion of the intervention to examine the muscle function, functional abilities, postural control and bone mineral density of the participants. It is anticipated that the outcomes of this pilot study for SMA may show if this intervention is safe, feasible and beneficial for children with SMA type III regarding to muscle function, functional abilities, postural control and bone mineral content and if there may be any related practical issues of this intervention to this population group. The outcomes also provide research evidence to clinicians if this intervention should be recommended to individuals of similar problems.
This study evaluates the effect of increase in testosterone levels in older males and the effects of decrease in testosterone levels in young males on muscle protein synthesis.
Total knee replacement, or arthroplasty, is the final clinical intervention available to relieve pain and functional limitations related to advanced stage knee osteoarthritis. Despite its beneficial effects, the early post-surgical period is characterized by the erosion of lower extremity muscle size and strength that cause further disability and slow functional recovery. While the detrimental effects of this period on muscle are widely recognized, the mechanisms underlying these adaptations are poorly understood and there are currently no widely-accepted clinical interventions to counter them
It is well known that periods of weight training lead to increases in skeletal muscle size and strength. In contrast, periods of inactivity such as bed rest or immobilization result in losses of skeletal muscle size and strength. However, individuals experience variable magnitudes of muscle size change in response to changes in mechanical tension, such that certain individuals experience large changes in muscle mass whereas others do not. What is not currently known, and will be the primary goal of the present investigation, is to determine whether individuals who gain the most muscle mass with exercise training also lose the most muscle when they are immobilized. The investigators hypothesize that individuals who gain the most muscle with training will also lose the most with immobilization.
The investigators will compare differences in quadriceps strength, leg girth, and functional outcome scores between two groups of patients after weeks 6 and 12 as well as 6 months following meniscus or articular cartilage repair/restoration requiring 6 weeks of non-weight bearing or limited weight bearing status in a brace at 0° degrees of knee extension. One group will receive BFR with standard post-operative rehabilitation for 12 weeks followed by the standard protocol progression for the remainder of the treatment program. The other group will receive standard post-operative rehabilitation without BFR for the duration of treatment program.
This is a multi-center, exploratory, non-comparative, and open-label study to investigate the safety, tolerability, PK, and PK/PD relationship of risdiplam in adults, children and infants with Spinal Muscular Atrophy (SMA) previously enrolled in Study BP29420 (Moonfish) with the splicing modifier RO6885247 or previously treated with nusinersen, olesoxime or AVXS-101.
The purpose of this study is to describe the changes in quadriceps muscle size and quality over the first 10 days on extracorporeal membrane oxygenation (ECMO) using ultrasound imaging. This study will also examine the relationship between those changes and muscle strength and level of physical function at day 10 and day 20 after ECMO commencement.
This study is designed to gain a better understanding of the mechanisms leading to muscle wasting and metabolic abnormalities in skeletal muscle of cancer patients.
International, multicenter, observational, longitudinal study to identify biomarker/s for Duchenne Muscular Dystropy (DMD) and to explore the clinical robustness, specificity, and long-term variability of these biomarker/s.
