23 Clinical Trials for Various Conditions
The purpose of this study is to determine whether Repetitive Transcranial Magnetic Stimulation (rTMS) can augment occupational therapy in improving motor function in children (10 years of age or older) and young adults (\< 21 years of age) with chronic hemiparesis from either stroke or cerebral palsy.
The purpose of this project is to assess the effects of four weeks of mirror-box training on weakness of one arm secondary to stroke. Primary measures are function and strength. Secondary measures will evaluate muscle tone, flexibility, and the subject's perception of their everyday function and improvement. Research Hypothesis: For chronic upper limb hemiparesis secondary to stroke, four weeks of mirror-box training with movement of the unaffected limb only results in a mean increase of 10 points on the Fugl-Meyer Test of Motor Recovery (Upper Extremity).
Stroke is the leading cause of disability in the United States, producing motor impairments that compromise performance of valued activities. Hemiparesis (or weakness in one arm) is particularly disabling, is the primary impairment underlying stroke-related disability, and the most frequent impairment treated by therapists in the United States. This study will test efficacy of a promising technique in reducing arm disability and increasing function, thereby improving outcomes and health, reducing care costs, for community dwelling patients with stroke-induced hemiparesis.
The purpose of this study is to assess efficacy, as well as safety, of Ropinirole in improving movement among patients with chronic stroke.
The goal of this clinical trial is to learn if a program that combines language and arm treatment can improve language and movement problems in people with chronic stroke. The mains questions it aims to answer are: * To determine the extent to which this combined treatment can improve language. * To determine the extent to which the combined treatment can improve arm movements. Researchers will compare the effects of this combined treatment with treatment that targets arm movements alone.
This study uses functional magnetic resonance imaging to map neural activity throughout the central nervous system during a shoulder abduction task to characterize what motor pathways are being used post-stroke.
The proposed study is a two-arm randomized clinical trial designed to assess the effects of the StrokeWear system on clinical outcomes over a period of 6-months in chronic stroke survivors. The Intervention group will use StrokeWear system in combination to a motor and behavioral home intervention whereas the Control group will follow usual care which consists of a home-exercise plan (HEP).
To assess the impact of a 12-week virtual seated physical intervention on cardiovascular health and wellness in people with chronic neurological impairments (CNI).
Physical therapists frequently use manual cueing as a tool to improve movement quality in persons recovering from stroke but evidence to support its effectiveness is lacking. The purpose of this graduate student research study is to determine the immediate and carryover effects of an integrated verbal and manual facilitation approach used by physical therapists during sit to stand training on the midline alignment, muscle activation and quality of movement in chronic stroke survivors with hemiplegia.
The objective of this pilot randomized controlled single blinded, parallel-group study is to detect change of the Action Observation (AO) and Repetitive Task Practice (RTP) combined practice schedule on upper limb motor impairment outcomes in chronic, moderately impaired stroke survivors.
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.
Stroke is the leading cause of long-term disability in the U.S. Individuals with hemiparesis due to stroke often have difficulty bearing weight on their legs and transferring weight from one leg to the other. The ability to bear weight on the legs is important during functional movements such as rising from a chair, standing and walking. Diminished weight transfer contributes to asymmetries during walking which commonly leads to greater energy expenditure. Moreover, deficits in bearing weight on the paretic leg contribute to lateral instability and are associated with decreased walking speed and increased risk of falling in individuals post-stroke. These functional limitations affect community participation and life quality. Thus, restoring the ability to bear weight on the legs, i.e., limb loading, is a critical goal for rehabilitation post-stroke. The purpose of this research is to identify the impairments in neuromechanical mechanisms of limb loading and determine whether limb loading responses can be retrained by induced forced limb loading.
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).
This pilot study will examine a combination therapy for adults with chronic, severe motor impairment of an arm after stroke. The intervention will combine brain stimulation with physical rehabilitation of the arm on the side of the body more-affected by stroke.
Study will look at the effect of a game-based, task-oriented home exercise program on adherence in persons with chronic (\> 6 months post) stroke as compared to a standard home exercise program. The study will also look at the effect of a game-based, task-oriented home exercise program on upper extremity motor function and occupational performance in persons with chronic (\> 6 months post) stroke as compared to a standard home exercise program. Finally, the study will look at barriers and facilitators to successful use of the game-based, task-oriented home exercise program in the home setting.
The ultimate goal of this project is to develop a functioning and clinically feasible method for restoring function to motor-impaired stroke survivors. This ultimate goal will be approached through two different means. The first method is to develop a functioning brain-computer interface that operates based on cortical activity ipsilateral to an intended movement on the motor-impaired side of the body. And secondly, to develop new methods of rehabilitation that involve stimulating peripheral muscles based upon cortical activity ipsilateral to intended movements. Finally, the study seeks to assess changes in functional connectivity as a result of using a BCI device.
The purpose of this protocol is to determine if individuals who had a stroke more than one year before entering the study and whose ankles remain substantially impaired are able to sense and move the affected leg better after 9-13 weeks of treatment with a robotic therapy device (AMES).
Ankle dorsiflexor weakness (paresis) is one of the most frequently persisting consequences of stroke. The purpose of this exploratory study is to compare two different treatments -- Contralaterally Controlled Neuromuscular Electrical Stimulation (CCNMES) and Cyclic Neuromuscular Electrical Stimulation (cNMES) -- for improved recovery of ankle movement and better walking after stroke.
Impaired hand function is one of the most frequently persisting consequences of stroke. The purpose of this study is to compare two different treatments -- Contralataterally Controlled Functional Electrical Stimulation (CCFES) and Cyclic Neuromuscular Electrical Stimulation (cNMES) -- for improved recovery of hand function after stroke.
Recent studies have demonstrated that electrical stimulation delivered over the skin increases the muscle strength as measured by a dynamometer in chronic stroke patients. We recently also found out that such stimulation enhances the ability of healthy brains to learn faster, enhancing the beneficial effects of the motor training. The purpose of this study is to find out if this stimulation can enhance the ability of stroke patients to experience plastic changes in the brain. It may aid in the development of new strategies for rehabilitation after brain injury in the future. A clinical and neurological exam will be administered. Each patient will participate in three different sessions separated by at least 48 hours: a 2-hour peripheral nerve stimulation to the weak hand, a 2-hour peripheral nerve stimulation to the leg, and no stimulation. The sessions will be randomly ordered. A magnetic resonance imaging scan of the brain will be done as well. Nerve stimulation will be done by transcranial magnetic stimulation (TMS). In TMS, the head is immobilized within a frame. An insulated coil wire is placed on the scalp and brief electrical current passed through it. Participants may be asked to perform movements, do simple tasks, or simply tense muscles. Electrical activity of the muscles will be recorded with a computer. Some experiments may be recorded on videotape. Participants must be stroke patients who have recovered to the point of being able to make thumb movements, and the stroke must have occurred more than 6 months ago.
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.
The investigators will study motor recovery after robot-assisted therapy after stroke. A small clinical trial will be conducted to quantify the central nervous system changes associated with robotic or standard training, and identify trends across high and low responders in terms of patterns of change in cortical activity and type of white matter connectivity.The investigators hypothesize that robot training will lead to larger improvements as compared to standard occupational therapy. The investigators hypothesize that high responders to the robot training will have reduced compensatory activation in the bilateral area and will connectivity in the motor tracts.
