Active clinical trials for "Paresis"

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.

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 project is a continuing study from the FEATHERS project (NCT02290353) which focuses on developing novel home therapy program for persons with hemiparesis. This study will focus on examining motor behaviour and adaptation in neurodevelopmental hemiparesis (cerebral palsy, acquired brain injury (ABI)). New algorithms for motion control involved in encouraging active movement are developed and will be tested, but the study has the same therapeutic goal and focus as the original FEATHERS project of creating an engaging at-home bimanual upper limb training program. By incorporating existing gaming technology, we hope to discover novel ways to adapt commercial motion tracking controllers and visual feedback into engaging rehabilitative learning tools. This study will focus on a basic science aspect of human bimanual movements that can be incorporated into future applications of the full FEATHERS project devices. We believe that together these approaches will yield interventions that significantly improve functional ability and lead to improved quality of life.

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.

Investigate development of an Innovative Instrument on Robot-Aided and Virtual Reality Rehabilitation for Intelligent Physical Training (i.e. gait and stepping) of Individuals post-stroke.

Hemiparetic gait is characterized by strong asymmetries that could severely affect the quality of life of stroke survivors. This asymmetry is due to motor deficits in the paretic leg and the resulting compensations in the non-paretic limb. In this study, the investigators aim to evaluate the effect of actively promoting gait symmetry in hemiparetic patients by assessing the motion and muscular activity of both paretic and non-paretic lower limbs. To this end, the investigators use a unilateral active Knee-Ankle-Foot Orthosis able to assist the paretic limb of hemiparetic patients during gait. The system is able to synchronize its action with the movement of the unassisted joints, promoting a natural and intuitive interaction. The device generates assistance to induce a healthy gait pattern on the paretic leg. The hypothesis is that a proper and natural interaction between the user and the exoskeleton would enable the patients to consider the robot action as a part of their own gait capability, improving their gait quality as consequence. Hemiparetic asymmetry is not only due to impairments in the affected limb, but also it is the consequence of biomechanical compensatory mechanisms that might arose in the non-paretic leg. The aim of this study is to assess the adaptation process of the subject to the exoskeleton assistance, and to evaluate the effects of such human-robot interaction in both paretic and non-paretic legs.

About two-thirds of adults in the United States are overweight or obese with likely adverse health consequences. A Moderate weight loss by dieting and exercise is recommended to improve health. We are interested to know whether eating dietary protein at different times of the day influences changes in body composition, muscle and indices of health. The purpose of this study is to examine the effects of within-day patterning of dietary protein intake (even vs. skewed) on energy-restriction and resistance training-induced changes in body composition, muscle size, appetite, and clinical health (including blood glucose and blood pressure).

The ArmeoSpring device is an exoskeleton (3 joints and 6 degrees of freedom) with integrated springs. The investigators hypothesize that 3 days of training for 6 weeks with the Hocoma Armeo Spring device will be efficient and more effective than one on one ArmeoSpring therapy.

The effect of surgery, in contrary to critical illness, on muscle weakness hasn't been thoroughly investigated. Recent data suggest that elective surgery may also induce muscle weakness. The neuro-endocrine stress response could be involved in the pathophysiology. Whether the mode of anesthesia/analgesia can influence muscle weakness, by influencing the neuro-endocrine stress response is unknown. Gaining insight in this matter could affect quality of care and benefit patient recovery and satisfaction.

The aim of this study was to investigate the effect of lateralization on the spatio-temporal characteristics of gait in individuals with hemiparesis.
