Filter by:Stroke often leads to long-term disability including upper extremity (UE) dysfunction even with the provision of timely rehabilitation services. Brain injury stemming from stroke, affecting the corticospinal system results in weakness, alterations in muscle tone and incoordination during the performance of functional tasks. Recovery of functional task performance after injury to the corticospinal system involves a residual neural network that engages the premotor cortex, frontal cortex and supplementary motor cortex. In particular, the dorsal premotor cortex (PMd) is anatomically and physiologically poised to reorganize and support motor recovery after corticospinal damage. The goal of this study is to determine the feasibility and efficacy of stimulating the ipsilesional PMd in adults with chronic stroke using noninvasive anodal transcranial direct current stimulation (tDCS) during the training sessions of a 4-week circuit-based, UE, task-related training (TRT) program. Pilot data from six adults, using anodal tDCS over the injured PMd just before each session of TRT, led to significant improvements in UE function in 5 of the 6 adults after only 4 weeks of training. We will assess the motor function of both arms using clinical assessments immediately before and after the 4-week TRT program. In addition to effects of tDCS-primed UE-TRT on clinical outcomes, we will use functional magnetic resonance imaging (fMRI) to determine the changes in neural network reorganization. We hypothesize that the training program will reveal significant improvement in motor function based on clinical assessment as well as significant global network changes based on resting state functional MRI and hybrid diffusion MR imaging. The long-term goal of this research is to develop an effective intervention strategy to improve UE function in individuals with moderate impairment from chronic stroke.
The purpose of the research is to develop a new medical device prototype to restore functional movement of an arm made weak due to a chronic stroke
After a stroke, it is very common to lose the ability to open the affected hand. The purpose of this study is to compare the effects of three different therapies on recovery of hand function after stroke and determine if any one is better than the other.
The purpose of the study is to determine the best treatment for the arm that has been affected by a stroke. The investigators plan to determine if the arm affected by a stroke will improve with a combination of motor priming and motor training. Motor priming provides a warm up for the brain so that the brain and body will better respond to treatment. There are two types of priming in this study. One is called bilateral motor priming which involves using both hands. Bilateral priming requires that the individual make continuous wrist movements in a low-tech gadget called the Exsurgo primer, a piece of equipment in which each hand goes between two plates that are connected together so that the stronger wrist moves the weaker wrist in and out at the same time. The second type of priming includes use of low intensity stimulation for your affected arm. The investigators expect the bilateral priming group will have more improvement. The study team anticipates enrolling approximately 76 individuals with stroke at Northwestern University and Shirley Ryan AbilityLab into this study. Each participant will have 24 visits. Nine visits will be for evaluation and fifteen for therapy. Each visit will be two to three hours depending on the type of visit and tests being done. Participants who are eligible and want to participate in this study will be randomized (selected by chance) to one of the two groups. The possible groups are: 1) bilateral priming plus motor training and 2) electrical stimulation priming and motor training. Participants are not blinded. Evaluation sessions consist of three separate days of testing and will occur at three time points: (1) before treatment starts; (2) after treatment is completed; and (3) 8 weeks later (follow-up evaluation: visits 22-24). There are three motor assessments, the Neuro-QOL (short form), and an evaluation of cortical excitability using TMS. After a stroke, there is often an imbalance of excitability between the affected and less affected parts of the brain. The imbalance will be measured using Transcranial Magnetic Stimulation (TMS), a technique used in neurorehabilitation research. TMS will not be used for treatment. There will also be a grip termination evaluation. This test will determine how long it takes to relax the affected hand after gripping an object.
A multi-site, interventional, non-comparative, single-arm trial to evaluate the safety of the ReWalk ReStore device in subjects with hemiplegia/hemiparesis due to ischemic or hemorrhagic stroke.
The goal of this research is to provide limb training in children with hemiplegia using a bimanual-to-unimanual training approach. Twenty pediatric patients aged 5-17 years with acquired brain injury will receive training on the bimanual-to-unimanual device for a period of 9 weeks. During the training, children use both arms to operate robotic arms to play a video game. We will assess changes in hand impairment after the training.
The purpose of this study is to examine the efficacy of MyndMove therapy in the early sub-acute, late sub-acute and chronic post-stroke patients. Other objectives include assessing the required doses of electrical current amplitudes, the usability of the device, and examining the overall safety.
The purpose of this study is to find out what are the best settings for applying electrical nerve stimulation over the skin for the short-term improvement of hand dysfunction after a stroke. The ultimate goal is to some day design an effective long-term training program to help someone recovery their ability to use their hands and function independently at home and in society. In order to know how to apply electrical nerve stimulation to produce a good long-term effect on hand dysfunction, we first need to know how to make it work best in the short-term, and improve our understanding of for whom it works and how it works.We will use a commercially available transcutaneous electrical nerve stimulation (TENS) unit to gently apply electrical nerve stimulation over the skin of the affected arm. This is a portable, safe and easy to use device designed for patients to operate in their homes.
Stroke is a neurovascular event characterized by impaired blood supply to the brain due to rupture or obstruction of certain cerebral arteries, which often results in hemiparesis and can affect individuals of any age and sex, being prevalent in the elderly population. Among the main treatments available for stroke rehabilitation, most of them demands an appropriate structure and high-qualified personnel. Searching for more affordable treatment options, several studies suggest the use of mental practice with motor imagery as a potential therapeutic tool, since it can be performed at any place or any time the patient wishes, including their own homes. Motor imagery can be defined as the covert cognitive process of imagining a movement of your own body(-part) without actually moving that body(-part). Within this context, the objective of this study is to investigate the effects of mental practice for mobility, gait function and speed and muscle strength of the lower limb in subacute post-stroke hemiparesis.
This study evaluates a new rehabilitation approach for stroke survivors in the chronic phase of recovery in which the combination of drug therapy (cyproheptadine) and active movement practice (AMP) is used to encourage increased voluntary muscle control and strength.
