Active clinical trials for "Muscle Weakness"

The purpose of this study is to assess the efficacy of non-invasive BCI-exoskeleton technology based on EEG patterns recognition matching to motor imagery in post-stroke patients with hand paresis.

Evaluate the use of Electromagnetic Muscle Stimulation for body contouring.

The purpose of this study is to test the hypothesis that creatine will accelerate adaptations associated with exercise in breast cancer survivors recently completing chemotherapy.

In recent years, suprainguinal fascia iliaca block (SFIB) has emerged as a reliable analgesic option for primary total hip arthroplasty (THA). In 2018, a new block was described, termed pericapsular nerve group block or PENG block, that selectively targets the articular branches of the femoral and obturator nerves while sparing their motor components. In this randomized trial, the investigators will compare US-guided SFIB and PENG block in patients undergoing primary THA. Since the main benefit of PENGB stems from its quadriceps-sparing effect, it was selected the incidence of quadriceps motor block (at 6 hours) as the primary outcome and the hypothesis that PENG block will result in significantly less motor block compared to SFIB.

Intensive care unit acquired muscle weakness (ICUAW), is a common disease which influence rehabilitation, extend mechanical ventilation and length of stay in intensive care unit, and affect quality of life at hospital discharge. To prevent ICUAW, different strategies of early mobilization are recommended. But all cannot be applied in all ICU patients. Some of them benefit from heavy therapies like circulatory assistance or renal replacement therapy for example, that limit mobilization. Cycloergometer is a tool that allows continuous passive mobilization in bedridden and even unconscious patients. Neuromuscular electrical stimulation (NMES) is an alternative that helps preserve muscle mass and limit muscle atrophy. Early bedside cycle exercise coupled with NMES is an interesting new approach where application of an electrical stimulation along specific motor nerves on each lower limb, generates muscles contractions and pedaling on cycloergometer. The aim of this study is to evaluate safety and feasibility of this coupled technique called Functional Electrical Stimulation (FES) Cycling, in ICU patients.

Unfortunately, hospital-acquired weakness is highly prevalent among COVID-19 hospitalized patients, who often require prolonged bed-rest or paralytics for an extended period of time in order to maintain oxygenation. Prolonged bed rest has been associated with pronounced loss of muscle mass that can exceed 10% over the 1st week, which leads to functional impairment and complications post-hospital discharge. Physical therapy and in-hospital mobility program may reduce the incident of hospital-acquired weakness, but they are often impractical for COVID-19 patients. In particular, conventional mobility programs are challenging for those who are being treated in an intensive Care Unit. The purpose of this study is to test feasibility and proof-of-concept effectiveness of daily use of lower extremity electrical stimulation (EE) therapy, as a practical solution to address lower extremity muscle deconditioning, to address chronic consequences of COVID-19 including hospital-acquired weakness.

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.

This study's primary objective is to determine the independent and combined effects of progressive resistance muscle strength training and testosterone on the development of sustainable improvements in physical function.

In several diseases in which muscle weakness is a determining factor for morbidity and mortality, inspiratory muscle training has been shown to be useful in improving the function of ventilatory muscles, delaying or minimizing the development of complications due to the reduction of inspiratory muscle strength. The breath-stacking technique emerges as an easily applicable alternative, and it can be used in poorly collaborative patients. The technique described in the literature aims to increase pulmonary volumes. This gain occurs with the coupling of a silicone mask on the patient's face, a unidirectional valve and with the expiratory branch occluded. Thus, inspirations occur sequentially in this medium, generating pulmonary hyperinflation and increasing the contractility power of the expiratory muscles, which are fundamental for coughing. This hyperinflation also improves the peripheral air distribution in the lungs by increasing intrathoracic pressure. The objective of this study is to evaluate the effect of the breath-stacking (BS) technique on the ventilatory muscle strength of young and healthy individuals.

Hemi-diaphragmatic palsy is a common undesirable effect of interscalene block, with an incidence of up to 100%. Mechanism of palsy is thought to be related to spread of local anaesthetic anterior to the anterior scalene muscle. We hypothesize that by injecting saline in this anatomical location prior to performing an interscalene block the incidence of phrenic palsy will be reduced.
