Active clinical trials for "Muscle Weakness"

The purpose of this study is to examine deficits in activation and motor patterns, as well as central drive in patients with rotator cuff tendinopathy. There are three specific aims: (1) determine the effect of acute pain relief on rotator cuff muscle activation in patients with rotator cuff tendinopathy, (2) determine the effect of exercise on rotator cuff muscle activation in patients with rotator cuff tendinopathy, and (3) compare rotator cuff muscle activation between patients with rotator cuff tendinopathy and healthy controls.

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.

Aging results in a gradual decline of physical abilities and consequently in functional impairments which increases the risk of falls in elderly people. It has been shown, that balance and resistance training can counteract the effects of aging. The aim of this study was to investigate effects of instability resistance training (IRT), combining balance and resistance training, on measures of muscle strength / power and balance for falls in healthy community-dwelling older adults. Therefore 75 elderly people, aged 65 - 80 years (Mage = 70.4; SD = 4.3 years) were assigned into three intervention groups: machine-based (M-RT), machine-based instability (M-IRT), free weight instability resistance training (F-IRT). All three groups exercised over 10-weeks with two training sessions per week. Assessment of muscle strength (e.g. maximal isometric leg extension strength), power (e.g. chair rise test) and balance (e.g. gait, functional reach test) was conducted before and after training. Based on the principle of training specificity, it is assumed, that groups to improve better within their respective training modality. Thus, the investigators hypothesis that regarding measures of strength and power, M-RT performs better than M-IRT, performs better than F-IRT. As to measures of balance, we hypothesis that F-IRT performs better that M-IRT, performs better than M-RT.

This is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of Immune Globulin (Human), 10% Caprylate/Chromatography Purified (IGIV-C) as a corticosteroid (CS)-sparing agent in subjects with CS-dependent Myasthenia Gravis (MG).

The purpose of this study is to evaluate safety, tolerability, pharmacokinetics/pharmacodynamics and efficacy of CFZ533 as an add-on therapy to standard of care in patients with moderate to severe myasthenia gravis (MG).

The purpose of this research study is to determine if exercise will help improve muscle strength, endurance, and quality of life in individuals with Pompe disease. This is a research study to further define the outcome of patients with Pompe disease treated with a combined diet and exercise therapy.

Respiratory muscle training (RMT) is considered a therapeutic strategy to improve respiratory muscle strength in mechanically ventilated (MV) patients and facilitates ventilator weaning. RMT aims at improving strength and endurance of respiratory muscles . However, scarce research exists regarding evaluation of RMT in MV patients and additionally studies differ in methods, RMT protocols and subjects included. There are not reports about Colombian studies evaluating RMT effects on MV patients. The aim of this study is to evaluate the effectiveness of respiratory muscle training in increasing respiratory muscle strength and improving weaning outcomes in MV patients who required ventilatory support for more than 48 hours at an Intensive Care Unit of an IV level Hospital in Cali during the period 2014-2015

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.

The improvement in inspiratory muscle function might result in beneficial changes in breathing pattern during whole body exercise. The hypothesis is the effect of inspiratory muscle training as an adjunct to a pulmonary rehabilitation program improves the breathing pattern during an incremental cycle exercise.

The purpose of this study is to determine if residual weakness after weight loss surgery leads to an increased risk of respiratory complications in the postoperative period.
