Stroke Clinical Trials

The purpose of this pilot study is to determine whether two weeks of multi-channel FES along with task-specific training will improve UE function when compared to traditional rehabilitation or usual care. The secondary purpose of this study is to find whether two weeks of multi-channel FES along with task-specific training will improve shoulder range of motion, grip strength, and patient reported function when compared to traditional rehabilitation or usual care in patients with unilateral stroke resulting in hemiplegia.The following null hypotheses are established for this study: There will be no difference in UE function when using multi-channel FES along with task-specific training compared to traditional rehabilitation or usual care in patients with first time stroke and hemiplegia during in patient stroke rehabilitation. There will be no difference in shoulder range of motion and grip strength when using multi-channel FES along with task-specific training compared to traditional rehabilitation or usual care in patients with first time stroke and hemiplegia during in patient stroke rehabilitation. There will be no difference in self-reported upper extremity function when using multi-channel FES along with task-specific training compared to traditional rehabilitation or usual care in patients with first time stroke and hemiplegia during in patient stroke rehabilitation.The research design for this experimental study will be a randomized controlled trial. The manipulated independent variable in this study will be 1) FES using Xcite with traditional therapy and 2) traditional therapy. The dependent variables in this study are the following: Upper extremity function measured by The Action Research Arm Test, The Box and Block Test, and The Nine-Hole Peg Test; Grip strength measured using a dynamometer; Range of motion at the shoulder measured using a standard goniometer; and Participants' perception of improvement in function measured by a modified Patient-Specific Functional Scale.

Individuals with low socioeconomic status (SES) are more likely to have a stroke, more disabled at 3 months, and less likely to be independently ambulatory. Individuals with low SES struggle to adhere to physician guidelines because of 1) increased disability leaves patients ineligible or unable to tolerate therapy, and 2) poor access to quality care i.e., lack of transportation to therapy. To reduce post-stroke disparity in low SES groups, we need to invest in development of novel tools that make therapy more accessible. For the past 5 years, the PI has been developing Startle Adjuvant Rehabilitation Therapy (START), a tele-enabled, low-cost treatment to improve upper-extremity therapy outcomes in individuals with stroke - in particular individuals with severe-to-moderate stroke. START is the application of a startling, acoustic stimulus (via headphones) which increases the intensity of practice, particularly in severe patient populations. START is adjuvant, meaning it does not replace clinical practice but instead enhances current evidence-based treatments. Objective: we seek to determine if START can be used to enhance functionally relevant movement of the upper extremity. Preliminary data: Individuals with severe-to-moderate disability from a stroke completed a remotely delivered, 3-day training of object manipulation with START. Box and Blocks, which was targeted during training, demonstrated a large increase under START (+47.1%) compared to Control (+3.3%). Modified functional reach was also increased under START (+8.9%) compared to Control (+1.1%). Impairment also decreased under START (Upper-Extremity-Fugl-Meyer: +8.6%) resulting in subject-reported increase in arm function both in quantity (Motor Activity Log: +26.2%) and quality (+20.2%). These results indicate that START can be deployed remotely and may prove a valuable, adjuvant tool to enhance functional upper extremity movement. We propose to perform a Phase 1 clinical trial on a larger cohort of 58 subjects, with a longer, 5-day training with the goal of establishing that START can 1) enhance functional movement of the upper extremity and 2) generate sustainable changes that impact quality of life. Impact: This proposal is significant because it tests a tool that has the potential to directly target the causes leading to disparity of care for individuals with low SES. A third (34%) of 6.5 million people in the U.S. with stroke are on Medicaid or uninsured. Our best evidence-based therapies (e.g., high-intensity, CIMT) and our emerging rehabilitation technologies (e.g., TMS, robotics) are inaccessible to our minority and low SES populations. START addresses disparity because it 1) targets individuals with severe disability, which disproportionally affects low SES and minority groups, and 2) is tele-enabled eliminating transportation which 60% of individuals with low SES report as a barrier to care. If successful, this study will set the stage for larger trials to establish 1) the effectiveness of START to be incorporated into traditional therapy and as well as patient compliance, adherence, and tolerance - particularly in low SES groups.

A stratified, parallel-group, double-blind, randomized controlled trial of remotely delivered START treatment to individuals with severe-to-moderate stroke (with recruitment focused on individuals with low SES) will be conducted. Subjects and assessors will be blinded to the condition making the experiment double blind. Specifically, subjects will be told that we are exploring a new therapy that using different sounds to improve therapy. Parallel group design will ensure that subjects in the Control group are unaware that their "sounds" are softer than the START group. Trainers may become aware that a loud sound is present thus a unique Assessor will evaluate clinical performance before and after training making the study double-blind. Fifty-four subjects will undergo baseline testing in the laboratory to establish their capacity for functional and expressive speech as well as their self-reported health-related quality of life (power analysis below). Next, subjects will participate in a high-frequency, word-picture verification/ auditory-repetition treatment, 2 hr/day for 5 consecutive days focusing on expression of words of functional significance (e.g., water, fall). Subjects will either receive training with START or without (Control). Subjects will be re-tested immediately following training as well as one-month post to assess retention. Aim 1 will evaluate capacity of START to enhance SLT outcomes by assessing the % change in clinical assessment of functional and expressive speech. Our preliminary data points to a robust response [details]. Aim 2 will focus on the capacity of these changes to 1) be retained and 2) impact subject's reported quality of life. NOTE: While we are planning in-person baseline, end, and retention testing, in response to COVID, we have established remote clinical screening using peer-reviewed validated techniques for WAB and ABA-2 (see Alternative Solutions). All preliminary data collected for this proposal were collected remotely via no-contact protocols. Read Less

The SIESTA-Rehabilitation protocol combines two sleep-promoting interventions, (1) empowering nurses to reduce unnecessary disruptions and (2) a systematic protocol to screen, diagnose, and treat sleep-disordered breathing, to determine its impact on relevant sleep and rehabilitation outcomes in the acute inpatient stroke rehabilitation setting compared to the standard of care. Our primary outcome is change in Quality Indicator (QI) score, a measure that has replaced the Functional Independence Measure (FIM) in the inpatient setting at the Shirley Ryan AbilityLab, between admission and discharge.

Previous studies of the exosuit technology have culminated in strong evidence for the gait-restorative effects of soft robotic exosuits for patients post-stroke by means of substitution for lost function. The present study builds on this work by suggesting that an exosuit's immediate gait-restorative effects can be leveraged during high intensity gait training to produce long-lasting gait restoration. Current gait training efforts are focused on either quality or intensity. They focus on gait quality often by reducing the training intensity to allow patients to achieve a more normal gait. In contrast, efforts focused on training intensity push participants without focusing on the quality of their movements. These intervention paradigms generally fail to substantially impact community mobility. In this study, the investigators posit that exosuits can uniquely enable an integration of these paradigms (ie, high intensity gait training that promotes quality of movements). For this protocol, exosuits developed in collaboration with an industry partner, ReWalk™ Robotics will be used. To evaluate the effects of REAL gait training, the investigators will use clinical measures of motor and gait function, locomotor mechanics and energetics, and physiologic measures that may infer on motor learning. The spectrum of behavioral and physiologic data that we will collect will enable us to understand more comprehensively the gait-restorative effects of REAL. Read Less

Strokes often cause a loss of communication ability, referred to as aphasia, as well as cognitive difficulties. Each stroke survivor has a unique pattern of strengths and weaknesses in communication and cognition, and a unique course of recovery. The BUILD study aims to understand the brain basis of these individual differences in stroke outcome. Participants with stroke as well as controls matched in age, educational background, race, and sex are examined using a combination of standardized and in-house tests of language and cognition to provide a detailed profile of strengths and weaknesses. Each participant will have between three and six sessions, including an MRI to measure details of the structure, function, and connections in the brain. The data are analyzed to test how patterns in the stroke lesion explain the patterns of communication and cognitive difficulties, and how patterns in the uninjured parts of the brain explain resilience and recovery from the stroke. Ultimately, we hope that BUILD will guide us toward new targets for brain stimulation treatments or other biologically based treatments that improve language and cognitive abilities after stroke.

People with spinal cord injury (SCI), stroke and other neurodegenerative disorders can follow two pathways for regaining independence and quality of life. One is through clinical interventions, including therapeutic exercises. The other is provided by assistive technologies, such as wheelchairs or robotic systems. In this study, we combine these two paths within a single framework by developing a new generation of body-machine interfaces (BoMI) supporting both assistive and rehabilitative goals. In particular, we focus on the recovery of muscle control by including a combination of motion and muscle activity signals in the operation of the BoMI. Read Less

Stroke survivors frequently show persistent gait deficits in their chronic stages even after years of intensive rehabilitation. This may be caused by diminished capability of re-acquiring motor skills post stroke. Thus, the overall purpose of this research project is to examine stroke survivors' capability of learning a novel leg task over 3 visits, 1-2 weeks apart. The capability of learning a new skill is then correlated with the individual's neurological functions (nerve activity and movement coordination) and her/his gait performance (gait speed, gait symmetry, and force production).

The risk of stroke and vascular dementia is high in individuals who have had a prior stroke or TIA, and in those who have vascular disease risk factors, such as high blood pressure, abnormal cholesterol, diabetes or pre-diabetes. These vascular risk factors can improve with exercise. This study will examine the impact of a 6 month, low intensity group exercise class on fitness, walking, balance, and brain health. This study will also collect fitness, walking, balance, and brain health outcome measures at baseline and post all other MERCE exercise and robotics interventions. Read Less
