Stroke Clinical Trials

To determine whether treatment with transauricular vagus nerve stimulation (taVNS) during the training of an affected upper limb of a patient with chronic stroke on a robotic motor task alters the motor impairment. Read Less

The purpose of this study is to investigate if a person with weakness or paralysis in one or both arms, can use the NuroSleeve combined powered arm brace (orthosis) and muscle stimulation system to help restore movement in one arm sufficient to perform daily activities. This study could lead to the development of a product that could allow people with arm weakness or arm paralysis to use the NuroSleeve and similar devices to improve arm health and independent function.

The purpose of this study is to examine the changes in reflex pathways in the paretic ankle plantarflexors in individuals with post-stroke hemiparesis using operant conditioning. We are recruiting 5 individuals with chronic post-stroke hemiparesis with foot drop in the affected leg to participate in the reflex training procedure. The study involves 40 visits with a total study duration of about 4 months. Read Less

The randomized study (in Phase II of the U44) compares the efficacy and durability of 9 weeks (18 sessions) of robot-assisted physical therapy (PTR) versus physical therapy (PT) alone on foot drop as assessed by gait biomechanics (ankle angle at initial contact, peak swing ankle angle, number of heel-first strikes - % total steps, gait velocity) and blinded clinician assessment (dorsiflexion active range of motion, ankle muscle strength, assistive device needs).

The overall goal of this study is to evaluate whether stimulation of two brain areas alongside behavioral speech-language therapy increases connectivity to improve language functions in stroke-aphasia patients. Read Less

This study aims to examine the acceptability of patients and occupational therapists in following a mental practice protocol and examine the effects of mental practice with individuals with severe upper extremity hemiparesis (weakness) following a stroke. Mental practice is an adjunctive rehabilitation therapy that involves thinking about a motor task without actually moving. Research has shown that mental practice is a safe and feasible intervention that is effective in improving arm movements after a stroke. Patients in the study will participate in audio-guided mental practice, five days a week for two weeks, completing the following tasks: wiping a table and picking up a cup. The patients' ability to move their affected arm will be measured before and after the study to determine the effect of mental practice. Patients and occupational therapists will complete a survey to determine their feelings about performing or facilitating mental practice. The authors hypothesize that the majority of patients and occupational therapists will find mental practice to be feasible/acceptable for the recovery of the affected arm. Furthermore, we anticipate the majority of patients that complete the mental practice protocol will demonstrate improvements in their arm movements. Read Less

In this research study, the investigators aim to test the usability and efficacy of the GaitBetter system for gait rehabilitation after stroke. Read Less

Investigators will determine the long-lasting effects of post-acute rehabilitation after traumatic brain injury and stroke. Investigators will also evaluate if the beneficial effects of rehabilitation continue after discharge from a rehabilitative program. Read Less

If a subject agrees to participate, the primary investigators will collect some basic information including age, height, and weight. Intake of some general questions regarding health and each subject will complete some tests that measure walking speed, cognition, and balance. During these tests participants will be asked to stand from a chair, walk up & down a staircase, walk over objects in a forward, backward, and sideways directions, walk around objects in forward and backward directions. After completing those tests, participants will be asked to repeat them while doing another task such as counting out loud, naming objects, or passing an object from one hand to another. At the end of the day, a step counter will be attached to each subject's ankle and you asked to wear it when awake for the next 7 days. Investigators expect that the evaluation will last 1 hour. After 7 days, subjects will return the step counter to the researchers and begin the exercise classes. The exercise classes will occur 2 days per week for 8 weeks. In the class participants will be asked to perform gentle exercises and use memory to improve brain functioning. Each class is expected to last 1 hour. At the conclusion of the exercise classes, investigators will again perform the gait, balance and cognitive tasks as we did before each started the class. Once a subject finishes all the exercise classes and testing, investigators will call one every week to see if you have had any falls at home. The calls will go on for 6 months. Read Less

The goal of this study is to develop a clinically feasible, low-cost, nonsurgical neurorobotic system for restoring function to motor-impaired stroke survivors that can be used at the clinic or at home. Moreover, another goal is to understand how physical rehabilitation assisted by robotic device combined with electroencephalograph (EEG) can benefit adults who have had stroke to improve functions of their weaker arm. The proposed smart co-robot training system (NeuroExo) is based on a physical upper-limb robotic exoskeleton commanded by a non-invasive brain machine interface (BMI) based on scalp EEG to actively include the participant in the control loop . The study will demonstrate that the Neuroexo smart co-robot arm training system is feasible and effective in improving arm motor functions in the stroke population for their use at home.The NeuroExo study holds the promise to be cost-effective patient-centered neurorehabilitation system for improving arm functions after stroke.

The purpose of this study is to assess the safety and efficacy of daily morning exposure to colored light in patients receiving acute inpatient rehabilitation services for stroke, traumatic brain injury, or non-traumatic brain injury with sleep disturbances such as poor nighttime sleep and/or excessive daytime sleepiness.In a two-arm randomized placebo-controlled study with pre-exposure and post-exposure assessments, we are comparing the effects of daily morning exposure to either blue light or red light on objective sleep quality, subjective sleep quality, functional rehabilitation outcomes, cognitive symptoms, fatigue, and neurological symptoms.
