This is a feasibility study to alter the Microsoft Kinect software to be used as a rehabilitation tool. The prototype used is still in the early developing stage. The purpose of this research study is to develop a prototype of altered Microsoft Kinect Software and determine its use in improving the function of the study subjects' weaker extremities. The altered software will allow a viewing of the mirror image of the involved limb as it is moved. However, the image that is viewed will reflect normal movement even if the limb cannot move normally. By viewing normal movement of the weaker limbs the "mirror neuron" network in the brain will become activated and will ultimately improve the function of the weaker side.
Post-stroke, people suffer various sensorimotor and cognitive deficits that lead to impaired balance control and gait functions thereby increasing the risk of falls. Despite undergoing exercise training in stroke rehabilitation to enhance balance control and gait functions, the risk of falls in the community-dwelling chronic stroke population persists. Given that motor and cognitive functions are required as a part of daily living, performing activities at home and in the community become challenging. Additionally, performance of daily living activities involves the simultaneous performance of motor and cognitive tasks known as dual-tasking. Based on previous literature, dual-tasking leads to deteriorated motor and/or cognitive task performance known as cognitive-motor interference. The pattern of cognitive-motor interference varies with the complexity and type of motor or cognitive task being performed. Dual-task gait and balance training has been adopted by many and identified to be a beneficial method to enhance overall functions. These studies have used Virtual-reality interface that provides immediate biofeedback, and may implicitly address certain domains of cognition (visuospatial awareness, attention) associated with risk of falls. However, such training is unable to train explicit cognitive domains such as executive functions that are highly associated with balance control, gait functions, daily living activities, and fall risk. Therefore, this pilot study aimed to identify the efficacy of cognitive-motor training using Wii-fit Nintendo to reduce cognitive-motor interference during dual-tasking.
Balance is controlled through a complex process involving sensory, visual, vestibular and cerebral functioning which get affected by various neurological disorders such as in stroke. Different types of exercises are designed to target to cope up with the imbalance developed due to these neurological disorders. This study aimed to compare the efficacy of dual-task training using two different priority instructional sets in improving gait parameters such as self-selected velocity, fast speed, step length, and stride length in chronic stroke patients.
This multi-site randomized controlled trial aims to investigate the effectiveness (increase of the walking speed in the 10 Meter Walk Test - 10MWT) of the robotic treatment with exoskeleton or end-effector system compared to the conventional rehabilitative treatment for the gait recovery after stroke, and to compare the possible different efficacy of end-effector and exoskeleton systems in the various post stroke disability frameworks. All the eligible subjects admitted to rehabilitation centers, both in subacute or chronic phase will be recorded. The experimental group will follow a set of robotic gait training by on the treadmill based robotic systems which does not provide the over ground gait training (Lokomat Pro - Hocoma AG, Volketswil, Switzerland; G-EO System - Reha technologies, Italy). While, the controll group will follow a traditional gait training composed of all those exercises which promote the recovery of walking ability (please, see the interventions details).
Stroke patients usually have difficulties with moving and are venerable to secondary problems such as sarcopenia and strength loss. These problems may accelerate the disability process during aging. It is well known that exercise helps to maintain or promote human fitness. This study is conducted to explore the beneficial effects of exercise and protein supplement on fitness and body composition among patients with chronic stroke.
A study of stereotactic, intracerebral injection of CTX0E03 neural stem cells into patients with moderate to moderately severe disability as a result of an ischemic stroke.
The purpose of this study is to examine the effects of the EMG-driven exoskeleton hand robotic training device on upper extremity motor and physiological function, daily functions, quality of life and self-efficacy in brain injury patients.
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).
Evaluate feasibility (acceptability, subject recruitment/retention, willingness to be randomized, and adherence rates) of delivering the Lee Silverman Voice Treatment®-BIG (LSVT®BIG) intervention with individuals with chronic stroke. Evaluate preliminary effect of the LSVT®BIG intervention on motor function and occupational performance with individuals with chronic stroke.
Motor skill training and transcranial direct current stimulation (tDCS) have separately been shown to alter cortical excitability and enhance motor function in humans. Their combination is appealing for augmenting motor recovery in stroke patients, and this is an area presently under heavy investigation globally. The investigators have previously shown that the timing of tDCS application has functional significance, that tDCS applied prior to training can be beneficial for voluntary behavior, and that tDCS effects may not simply be additive to training effects, but may change the nature of the training effect. The investigators have separately reported in a randomized-controlled clinical trial, that upper limb robotic training alone over 12 weeks can improve clinical function of chronic stroke patients. Based on our results with tDCS and robotic training, the investigators hypothesize that the same repeated sessions of robotic training, but preceded by tDCS, would lead to a sustained and functional change greater than robotic training alone. The investigators will determine if clinical function can be improved and sustained with tDCS-robotic training and cortical physiology changes that underlie functional improvements.
