Active clinical trials for "Paresis"

Our objective was to determine if an ultrasound guided ACB can preserve quadriceps strength, thus minimizing weakness of knee extension compared with ultrasound guided femoral nerve block. Our primary outcome was the percent of maximum voluntary isometric contraction (MVIC) of knee extension preserved at 30 mins after either an ACB or FNB. Secondary outcomes included MVIC of knee extension at 60 min, hip adduction at 30 and 60 mins, and assessment of fall risk with the Berg Balance Scale (BBS) at 30 minutes.

The purpose of this research study is to show that a computer can analyze brain waves and that those brain waves can be used to control an external device. This study will also show whether passive movement of the affected hand as a result of brain-based control can cause rehabilitation from the effects of a stroke. Additionally, this study will show how rehabilitation with a brain-controlled device may affect the function and organization of the brain. Stroke is the most common neurological disorder in the US with 795,000 strokes per year (Lloyd-Jones et al. 2009). Of survivors, 15-30% are permanently disabled and 20% require institutional care (Mackay et al. 2004; Lloyd-Jones et al. 2009). In survivors over age 65, 50% had hemiparesis, 30% were unable to walk without assistance, and 26% received institutional care six months post stroke (Lloyd-Jones et al. 2009). These deficits are significant, as recovery is completed after three months (Duncan et al. 1992; Jorgensen et al. 1995). This large patient population with decreased quality of life fuels the need to develop novel methods for improving functional rehabilitation. We propose that signals from the unaffected hemisphere can be used to develop a novel Brain-Computer interface (BCI) system that can facilitate functional improvement or recovery. This can be accomplished by using signals recorded from the brain as a control signal for a robotic hand orthotic to improve motor function, or by strengthening functional pathways through neural plasticity. Neural activity from the unaffected hemisphere to the affected hemiparetic limb would provide a BCI control in stroke survivors lesions that prevent perilesional mechanisms of motor recovery. The development of BCI systems for functional recovery in the affected limb in stroke survivors will be significant because they will provide a path for improving quality of life for chronic stroke survivors who would otherwise have permanent loss of function. Initially, the study will serve to determine the feasibility of using EEG signals from the non-lesioned hemisphere to control a robotic hand orthotic. The study will then determine if a brain-computer interface system can be used to impact rehabilitation, and how it may impact brain function. The system consists of a research approved EEG headset, the robotic hand orthotic, and a commercial tablet. The orthotic will be made, configured, and maintained by Neurolutions. Each participant will complete as many training sessions as the participant requires, during which a visual cue will be shown to the participant to vividly imagine moving their impaired upper extremity to control the opening and closing of the orthotic. Participants may also be asked to complete brain scans using magnetic resonance imaging (MRI).

Prolonged critical illness renders survivors with increased long-term morbidity associated with high healthcare costs. Muscle weakness and fatigue are reported as the main contributors to long-term poor functional outcomes. Emerging evidence for early mobilisation demonstrates reduction in the number of ventilator days and hospital length of stay. It has been demonstrated that daytime motoring (passive and active) can improve functional capacity in intensive care patients. The aim of the proposed study is to evaluate the effect of cycling exercise in patients on mechanical ventilation appointed to weaning process.

The aim of this study is to compare the effect of EMS and conventional physical therapy on strength and muscle mass and development in adult patients with severe sepsis and septic shock.

This research trial studies the effect of an online, live and interactive strength training program on physical function and strength in older adults with prediabetes.

Ventilator-induced diaphragmatic dysfunction is a common issue in critically ill patients. Muscle stimulation has shown to have beneficial effects in muscle groups on the extremities. A non-invasive way to stimulate the diaphragm would be the electromagnetic stimulation but it is currently unclear if that is feasible. In this proof-of-concept trial the primary aim is to show that it is possible to induce a diaphragmatic contraction leading to an inspiration with a sufficient tidal volume via an external electromagnetic stimulation of the phrenic nerve in obese patients.

Stroke patients who have little or no voluntary movement in the hand on the more affected side of their body more than one year after stroke have few treatment options. This project proposes to test the efficacy of a form of Constraint-Induced Movement therapy designed for patients with such severe impairment in conjunction with an agent, fluoxetine, which has been shown in some studies to enhance brain neuroplasticity in response to training. Constraint-Induced Movement therapy, which is abbreviated CIMT, is a form of physical rehabilitation based on basic research in neuroscience and behavioral science. If the project is successful, an efficacious, evidence-based therapy will become available to stroke patients for what is now a largely untreated condition

Early mobilization (from the first day if possible), first passive and then passive and active, is recommended for critically ill patients in whom it reduces the duration of mechanical ventilation, the length of hospital stay, improves functional status, muscle strength and quality of life after hospital discharge. The early addition of leg bicycling on a cyclo-ergometer is now part of common practice in the ICU. It can preserve or improve muscle strength and further increase the beneficial effects of early mobilization. Electrical muscle stimulation of the quadriceps, is practiced in some intensive care units, and it should, in theory, also through an improvement of muscle strength, increase the beneficial effects of early mobilization. We hypothesized that early quadriceps electrical stimulation and early work on a cyclo-ergometer associated with a standard protocol of early passive/active mobilization in the ICU may improve muscle function and reduce the duration of mechanical ventilation, length of stay, the number of readmissions and improve the quality of life in the mid term in critically ill patients, as compared to a conventional protocol of early passive/active mobilization.

This randomized controlled trial was designed to investigate whether a daily training session using a bedside cycle ergometer, started early in stable critically ill patients with an expected prolonged ICU stay, could induce a beneficial effect on exercise performance, quadriceps force and functional autonomy at ICU and hospital discharge compared to a standard physiotherapy program.

The purpose of this study is to investigate whether neuromuscular electrostimulation (NMES) will decrease ICU-associated weakness. The investigators believe that 60 minutes of daily NMES will improve strength and function in those who have had extended ICU stays, as well as decrease critical illness myopathy as an etiology of weakness in the critically ill.
