Filter by:The investigators know that peripheral muscle weakness and exercise intolerance are prevalent (56%) in cystic fibrosis (Trooster et al, 2009). Physical inactivity is likely to be an important underlying factor. Those conditions are associated with a poor prognosis (Nixon et al, 1992). The effect of intravenous antibiotherapy on peripheral muscle and physical activity remains unclear. The aim of the study is to evaluate the impact of intravenous antibiotherapy on peripheral muscular strength in patients with cystic fibrosis (adults and children) who receive intravenous antibiotherapy for an acute exacerbation or electively (decline in lung function without exacerbation).
Introduction: Lower extremity weakness associated with musculoskeletal pathology can cause activity limitations. Physical therapy intervention in the form of exercise is commonly directed at improving muscular performance, however, neuromuscular adaptations may limit the effectiveness of traditional strengthening exercises. Manual therapy techniques have been used as a disinhibitory intervention to increase muscle activation and strength before participating in strengthening exercises or performing functional tasks While there is recent evidence to support joint mobilization as a valuable manual therapy disinhibitory intervention Currently, there is no evidence to substantiate anecdotal experience that a HVLAT hip distraction mobilization improves muscle performance in subjects with lower extremity pathology and lower extremity weakness. The purpose of this study was to determine if a HVLAT hip distraction mobilization would result in an immediate change of maximal force output of the quadriceps, gluteus maximus and gluteus medius. Methods: Forty individuals with a lower extremity pathology volunteered for this study. Inclusion criteria were having a unilateral musculoskeletal pathology, being greater than 18 years of age, 10% decrease in muscle strength in symptomatic side compared to healthy side, and absence of medical precautions that would prevent a maximal effort strength test and exclusion criteria included individuals with a history lower extremity recent muscle or tendon ruptures (within the past 6 months) and postoperative knee, hip and ankle surgery. Demographic data, including diagnosis from referring physician were collected. All subjects completed the Lower extremity function scale (LEFS). A single evaluator blinded to the involved extremity was responsible for quadriceps, gluteus medius and maximus strength analysis pre and post mobilization of both symptomatic and non-symptomatic sides. The subject underwent the HVLAT hip distraction mobilization of the symptomatic side, and an immediate re-assessment of strength of both symptomatic and non-symptomatic sides followed the mobilization.
Two independent, but interrelated conditions that have a growing impact on healthy life expectancy and health care costs in developed nations are the age related loss of muscle mass (sarcopenia) and obesity. Sarcopenia affects approximately one third of adults over 60 years of age and more than 50% of those over 80 years, which is of concern when one considers that the most rapidly expanding population demographic in the UK is adults >80 years of age. Skeletal muscle is important in regulating blood glucose and insulin sensitivity. Thus, sarcopenia may play a role in exacerbating insulin resistance and progression toward Type II diabetes (T2D). Indeed, the highest incidence of T2D in the UK has been noted to occur in adults >65 years. Obesity is a major risk factor for chronic diseases including T2D and cardiovascular disease. Progression towards obesity is associated with a concomitant decrease in muscle mass, producing an unfavorable ratio of fat to muscle. Thus, obesity in old age may exacerbate the progression of sarcopenia. For the proposed study the investigators will conduct preliminary laboratory tests to characterize body composition, insulin sensitivity, systemic inflammation, aerobic capacity and muscle protein metabolism (in the fasted and fed state) in healthy older and obese older adults for comparison against healthy young individuals.
The study evaluates the feasibility of a staff-lead workout program, 3-Step Workout for Life, in a local senior living community. Eligible participants will complete assessments before and after the workout program.
The purpose of the study is to evaluate the clinical efficacy of UCB7665 as a chronic-intermittent treatment in subjects with generalized myasthenia gravis (MG) who are classified as moderate to severe.
Myasthenia gravis is an autoimmune disorder of neuromuscular transmission, characterized by fluctuating muscle weakness and fatigability. In isolated ocular myasthenia, when only the extraocular muscles are involved, most common ancillary tests, such as acetylcholine receptor autoantibodies and repetitive nerve stimulation, are often negative. A simple, quick and non-invasive test for ocular myasthenia based on ocular vestibular evoked myogenic potentials (oVEMP) was recently developed. The main goal of the study is to validate repetitive oVEMP stimulation in a blinded diagnostic accuracy study in order to facilitate early and accurate diagnosis of ocular myasthenia.
Purpose: To conduct a pilot study of the effect of Cranial Laser Reflex Technique (CLRT) compared with sham laser on hamstring muscle flexibility, strength, and pain pressure threshold. Participants: Active, young adults ages 18 to 35. Procedures: A two-visit, assessor and participant-blinded crossover study with 1-week washout. Subjects will complete three functional hamstring tests before and after CLRT and sham laser treatment. Subjects will also complete questionnaires to assess their expectations and perceptions of the interventions.
The SARA-OBS is a single arm phase 2 clinical trial, with no investigational product and no therapeutic intervention that will be conducted in three European countries, (Belgium, France and Italy), and in the US. 300 community dwelling older adults (men or women≥65 years) reporting loss of physical function and at risk of mobility disability, will undergo mobility functional evaluation and Dual-energy X-ray Absorptiometry DXA scan for body composition determination twice, at six-month interval. Participants aged ≥ 65 years complaining of poor physical function will be selected to perform SPPB (Short Physical Performance Battery)tests. Those with SPPB scores ≤ 8/12 will be selected to perform body composition analysis with DXA Scan. Participants with ALM/BMI < 0.789 in men and 0.512 in women will be included. The investigational phase will comprise two main visits: the inclusion visit and the 6-month visit. Both the 6-minute walk distance test and the 400-metre walking test will be administered at the main visits. Patient Reported Outcomes (PROs) will be completed by the patients at the same visits.
It is well documented that both balance and resistance training have the potential to mitigate intrinsic fall risk factors in older adults. Recently, it was shown that a simultaneously executed balance and resistance training, namely resistance training on uneven surfaces is an eligible, effective and safe alternative training program to mitigate intrinsic fall risk factors in older adults. However, knowledge about the effects of specific adductor and abductor training has advantages over traditional resistance training and resistance training on unstable surfaces regarding forward propulsion. Further, the effects of different kinds of resistance training on cognition, especially embodiment is investigated.
Creatine is a nutritional supplement that is often ingested to improve exercise performance. The advent of a new product that is applied to the skin overlying muscle offers potential benefit, if the creatine can be targeted to specific muscles. The investigators are testing a novel creatine cream to determine the effects on human muscular performance. The investigators are assessing whether 7 days of topical creatine application is additive to orally-ingested creatine for improving muscular power (determined by knee extension).
