Active clinical trials for "Paresis"

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.

This study aims to assess whether the NeuroLutions Upper Extremity Rehabilitation System (known as IpsiHand) will help stroke patients regain strength and functional movements in their arm. The IpsiHand system involves using a hand robotic device that is controlled by brain waves, known as a Brain-Computer Interface (BCI). By using the device, participants will be harnessing brainwaves from the side of their brain not affected by stroke to control the robotic device on the hand that is weaker from the stroke.

Recovery of upper limb and hand gestures is fundamental for autonomy restoration after stroke. Innovative technologies are a valid support for the delivery of rehabilitation treatments. Embedding surface electromyographic (sEMG) into wearable devices, allows the customisation of rehabilitation exercises, based on the clinical profile of each patient.

Background: Outpatient continuous interscalene brachial plexus blocks are used to control pain after shoulder surgery, with infusions of 0.125% bupivacaine or 0.2% ropivacaine. There have been no studies comparing the effects of these two formulations. The major concern is hemidiaphragmatic paresis, and since ropivacaine preferentially blocks sensory fibers, it may cause less blockade of the phrenic nerve. This study was to evaluate the effects of continuous interscalene brachial plexus infusions, with the hypothesis that respiratory function is more affected by 0.125% bupivacaine than 0.2% ropivacaine, with equal effects on pain relief. Methods: All patients underwent baseline spirometry and ultrasound evaluation of diaphragmatic excursion, followed by interscalene catheter placement for their surgery, then randomized to receive a pump containing 0.2% ropivacaine or 0.125% bupivacaine. Patients returned to the hospital the following day for spirometry, ultrasound reevaluation, and evaluation of their pain level since discharge.

The purpose of this study is to assess the effectiveness of a regular walking program (which inevitably involves human interaction) compared to a usual care condition and to a human interaction condition (without the extra walking program) in individuals residing in Long-Term Care (LTC). Outcomes of interest include: balance, strength, mobility, endurance, walking distance; rate and severity of falls; activities of daily living; mood and behaviour. It is hypothesized that participants taking part in the walking program will demonstrate maximal benefits compared to the no treatment control group (usual care) and the participants who will only receive social interaction. It is expected that benefits of the walking program will include decreased fall rates, and improved balance, endurance, strength, mood, behaviour, activities of daily living and quality of life indices. Given research findings that the addition of pleasant activities improves resident mood (Teri et al, 1997; 2003), it is expected that participants in the social interaction only group will demonstrate improvements in mood and other indices of quality of life.

Study purpose This study will explore whether an additional rehabilitation program that focus on either upper or lower extremity training facilitate the recovery in upper or lower extremity. The recovery in both neurological status and motor functions will be explored.

Intensive care unit-acquired muscle weakness (ICUAMW) is a common problem following an ICU admission and is associated with prolonged hospitalization, delayed weaning and increased mortality. Up to 25% of patients requiring mechanical ventilation (MV) for greater than 7 days develop ICUAW, and this figure may rise to 50-100% in the septic population. Long-term follow-up studies of survivors of critical illness have demonstrated significantly impaired health-related quality of life and physical functioning up to 5 years after ICU discharge, with weakness being the most commonly reported physical limitation. Early rehabilitation has been shown to be safe and feasible; however, commencement is often delayed due to a patient's inability to cooperate. An intervention that begins early in ICU admission without the need for patient volition may be beneficial in attenuating muscle wasting. Therefore, this study aims to evaluate the effect of neuromuscular electrical stimulation and early physical activity on ICU acquired muscle weakness in mechanically ventilated patient

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.

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.

The purpose of this study is to test an innovative, advanced FNS microstimulator technology developed by the Alfred Mann Foundation (Santa Clarita, CA) called, the Radio Frequency Microstimulation (RFM) Gait System that promises to provide FNS training for restoration of functional gait components in a manner at least as efficacious as current investigational FNS systems. The design features of the RFM Gait System are intended to address the problems with the current FNS systems. The RFM implant devices are small enough to be inserted using only a 5 mm incision[3]. Because both the electrode (anode and cathode) are contained within the microstimulator, there are no lead wires traversing the skin, joints, or torso/limb junctures. Individual RFMs can be inserted at the motor points and nerves of each of the paretic muscles in the involved limb and coordinated using radio frequency technology.
