Stroke

This project will develop a wearable rehabilitation robot suitable for in-bed acute stage rehabilitation. It involves robot-guided motor relearning, passive and active motor-sensory rehabilitation early in the acute stage post-stroke including patients who are paralyzed with no motor output. The early acute stroke rehabilitation device will be evaluated in this clinical trial.

Background: Stroke is the fifth leading cause of death in the United States. It is also a leading cause of disability. More than 70% of people who survive strokes have mental impairment or dementia. Medical factors, such as the severity of the stroke, affect whether a person will have mental impairment afterward. But social factors, such as education and ethnicity, seem to play a role as well. Researchers want to learn more about how social and lifestyle factors affect a person s chances of maintaining mental functions after a stroke. Objective: To better understand how social and lifestyle factors affect the risk of mental impairment after a stroke. Eligibility: People aged 18 years and older who had a stroke and a brain scan while they were enrolled in NIH Study 01N0007 (Natural History of Stroke Study). Design: Participants will have 1 study visit, by telephone. The call will last about 45 minutes. Participants will talk about their health since their stroke. They will answer questions about themselves. Topics will include: * Their race * Education * Ethnicity * Employment * Marital status * Residence address * Recent health history * Medical insurance They will have tests of their memory, attention, and language skills. They will repeat numbers and words forward and backward. Researchers will look at the data and imaging scans collected during participant s enrollment in NIH Study 01N0007. This data will include: * The hospital that first saw the participant at the time of their stroke. * The type of imaging that was first used then. * The primary diagnosis at admission. * Other medical details.

The goal of this clinical trial is to learn if wearable sensor data visualization on smartphones can improve the use of the stroke-affected limb during everyday activities. Chronic stroke survivors (\>12 months from onset) ages 18-80 years old with residual upper extremity motor impairments may be eligible to participate. The main question it aims to answer is: Does the mobile health (mHealth) intervention help to improve the use of the stroke-affected upper-limb during daily living? The study is designed so each participant serves as their own control. Researchers will compare information from the baseline and intervention time periods to see if visualizing the data on the smartphone impacts the participant's daily use of the arm. Participants will be asked to wear a set of wearable ring and wrist sensors and interact with a custom-designed smartphone app, aiming to increase the use of their stroke-affected limb during daily activities as much as possible. They will receive feedback from the app, communicate with study therapists, participate in goal setting, complete clinical assessments, and share about their experience using the system during a virtual interview.

This study will examine the effect of TMS on people with stroke and aphasia as well as healthy individuals.

This study innovatively proposes an "environment-perturbation balance training (E-PBT)" intervention, which delivers stable, graded environmental perturbations to keep the challenges within the manageable range. This approach can significantly reduce fear, align with the psychological characteristics of subacute stroke patients, and improve training engagement and safety, thereby filling the current research gap that has insufficiently addressed subacute patients and those with moderate-to-low functional levels. By altering the size and angle of the support surface, this training heightens patients' alertness and psychological adaptability, prompting them to actively integrate sensory information and adjust motor strategies. In turn, this can more effectively reshape internal model of balance control and facilitate genuine neuroadaptive learning in the brain. Moreover, this training more closely mimics real-life fall scenarios, with the aim of directly cultivating the proactive postural control and strategic decision-making abilities required in daily living. This study aims to systematically evaluate the efficacy of this E-PBT intervention on functional recovery in patients during the subacute stage of stroke through a prospective randomized controlled trial, and to explore its potential effects on balance ability, activities of daily living, and overall functional outcomes, thereby providing a more effective and clinically translatable new strategy for post-stroke rehabilitation.

The aim of this phase is to examine the feasibility and acceptability of the Augmented Reality (AR)-based and electroencephalography (EEG)-based neglect detection and rehabilitation tool.

This study will assess the effects of transcranial alternating current stimulation (tACS) on language recovery after stroke as well as healthy language functions.

This study aims to evaluate the effect of a personalized technology-based rehabilitative intervention on Upper Limb (UL) motor function and capacity recovery in People with Stroke (PwS). The study is single-cohort study in which eligible participants will undergo baseline and follow-up clinical and instrumental assessments over a 4-5 week period. The intervention consists of a personalized and specific upper limb technology-based rehabilitation programme delivered three times per week for a total of 12-15 sessions. Each session lasts approximately one hour and is integrated with conventional rehabilitation treatments. Primary outcomes include Fugl-Meyer Assessment for Upper Extremity (FMA-UE) and Action Research Arm Test (ARAT). Secondary outcomes include instrumental assessment of active range of motion and grip strength.

The goal of this study is to determine the effects of lab and home-based technology guidance during movement training post-stroke. The study will compare movement training informed by lab-based technology to training delivered with technology at home. The main questions it aims to answer are: * How well do lab and home-based technologies help individuals post-stroke improve their movement patterns? * Is there a difference in improvement between the in-lab and at-home training groups? * Which technologies lead to the most improvement?

This study aims to examine the associations of interoceptive awareness and interoceptive accuracy with plantar superficial sensory threshold, knee joint proprioception, pain intensity, and dynamic balance performance in cognitively intact individuals with chronic hemiplegia. Hypotheses are: * H0: There is no significant relationship between interoception and light touch, proprioception, pain, or dynamic balance performance in cognitively intact individuals with chronic hemiplegia. * H1: There is a significant relationship between interoception and light touch, proprioception, pain, or dynamic balance performance in cognitively intact individuals with chronic hemiplegia All participants will undergo a single assessment session and will not be invited for any treatment or follow-up evaluation. Participants will not take any intervention.

This study aims to investigate the rehabilitative effects and synergistic potential of combining Fastigial Nucleus Stimulation (FNS) with Sling Exercise Training (SET) on motor function in patients with post-stroke hemiplegia. Hemiplegia after stroke often results in unilateral motor impairment, balance dysfunction, and decreased proprioception. Although traditional rehabilitation methods can improve certain functions, they are often limited by insufficient central targeting and inadequate activation of deep core muscles, making it difficult to fundamentally repair damaged motor control circuits. FNS, as a non-invasive neuromodulation technique, can precisely target the fastigial nucleus-a critical hub for motor coordination and balance control-thereby modulating neuroplasticity and promoting regional cerebral blood flow to optimize cortical function. SET, on the other hand, utilizes an unstable sling system to efficiently activate deep core muscles (such as the transversus abdominis and multifidus), enhance proprioceptive input, and promote neural reorganization. Based on the concept of "central regulation-peripheral enhancement," this study hypothesizes that the combination of FNS and SET can create a bidirectional intervention pathway, breaking the vicious cycle between central damage and peripheral dysfunction, and achieving a "1+1\>2" therapeutic effect. This study employs a randomized, double-blind, sham-controlled design and plans to enroll 54 eligible patients with post-stroke hemiplegia (aged 18-70 years, within 6 months of onset). Participants will be randomly assigned to three groups: Group A (FNS + sham SET), Group B (sham FNS + SET), and Group C (FNS + SET). FNS will be delivered using high-precision electrodes placed over the bilateral mastoid regions, with a stimulation frequency of 180 Hz and an intensity of 2 mA (sham stimulation at 0.1 mA) for 20 minutes per session. SET will include supine and prone bridging exercises for 30 minutes per session, while sham SET involves suspension without active movement. All patients will be assessed before and after the intervention using the Berg Balance Scale, Fugl-Meyer Assessment, three-dimensional gait analysis, trunk control test, and proprioceptive measurement instruments. The sample size was calculated based on previous data for lower extremity Fugl-Meyer scores (effect size f = 0.502), with an estimated 20% dropout rate, resulting in a target of 54 participants. The innovation of this study lies in its first-time combination of FNS-a more targeted neuromodulation approach-with SET-a high-intensity sensorimotor integration training-and the use of sham controls to precisely quantify the individual contributions of each intervention and validate the synergistic effect of central-peripheral co-stimulation. Potential risks will be strictly managed: FNS may cause localized tingling or mild headache, which can be addressed by adjusting or pausing stimulation; SET will be conducted under the supervision of trained therapists with individualized intensity adjustments to prevent muscle soreness or falls. All adverse events will be documented and managed promptly. The findings of this study are expected to provide an effective, non-invasive central-peripheral synergistic rehabilitation strategy for post-stroke hemiplegia and offer evidence-based guidance for clinical practice and future research.

This trial tests a promising new intervention to promote post-stroke neural reorganization and functional recovery. The Q Therapeutic (BQ 3.0) is a wearable medical system that produces and delivers non-invasive, extremely-low-intensity and low-frequency, frequency-tuned electromagnetic fields in order to stimulate neuronal networks with the aim of reducing disability and promoting neurorecovery. This trial is a prospective, single-arm, open-label, single center clinical trial designed to evaluate the safety, feasibility, and efficacy of the Q Therapeutic (BQ 3.0) System in the rehabilitation of people with chronic stroke.

The purpose of this research study is to evaluate whether telerehabilitation targeting arm movement, when added to usual care, improves arm function and reduces global disability after stroke, compared to usual care alone. Patients with arm weakness due to stroke that happened in the past 90-150 days will be randomized into one of two groups: \[1\] TR and usual care; \[2\] usual care only (no TR), but people in the usual care group will be offered TR once the study is done. TR consists of 70 minutes/day of activities targeting arm function, 6 days a week for 6 weeks.

Music therapy is widely used in relational and rehabilitation settings. In addition to Neurologic Music Therapy and other music-based techniques, "sonification" approaches were recently introduced in the field of rehabilitation. The "sonification" can be defined as a properly selected set of sonorous-music stimuli are associated with patient movements mapping. In fact, the auditory-motor feedback can replace damaged proprioceptive circuits with a consequent improvement of the rehabilitation process. Interventions with "sonification" facilitate sensorimotor learning, proprioception and movements planning and execution improving global motor parameters. This study proposes the use of musical auditory cues which includes the melodic-harmonic component of the music. This kind of sonification makes the feedback pleasant and predictable as well as potentially effective. The investigators propose to apply and assess the effectiveness of this kind of sonification on gait training and other secondary outcomes in stroke, Parkinson's disease and multiple sclerosis population. Also, the investigators will assess the impact of "sonification" on the level of fatigue perceived during the rehabilitation process and on the quality of life. The study is a multicenter randomized controlled trial and will involve 120 patients that will undergo standard motor rehabilitation or the same rehabilitation but with the sonification support. The interventions will be evaluated at the baseline, after 10 sessions, after 20 sessions and at follow-up (one month after the end of the treatment). The assessment will include functional, motor, fatigue and quality of life evaluations. The collected data will be statistically processed.

The purpose of this study is to evaluate a new virtual reality (VR)-based rehabilitation program designed to help stroke survivors improve their walking abilities in real-world settings. By comparing immersive VR-assisted overground gait therapy to contemporary non-immersive, treadmill-based VR therapy (i.e., C-Mill), the investigators aim to determine its effectiveness in enhancing mobility and quality of life for stroke survivors.

The rates of cognitive decline and dementia after stroke are disproportionately high. Strategies that can protect the brain early after the stroke event could reduce the future risk of cognitive decline and dementia in these patients. Although physical exercise is usually recommended after stroke, there is very little information about the protective effect of exercise implemented in early stages of recovery as a potential protective measure against cognitive decline and dementia risk in these patients. This study will investigate the effect of a multimodal exercise intervention implemented early after the stroke event on cognition and on a selected group of markers that can predict cognitive decline and dementia risk.

This study aims to pilot "Maya," a mobile cognitive behavioral therapy app, for use in adults with stroke experiencing depression and/or anxiety. This study will assess the acceptability, feasibility, and preliminary efficacy of Maya within the acute rehabilitation period.

Stroke is the leading cause of acquired motor disability in adults. Six months post-stroke, 50% of patients have not regained active finger extension, and 80% retain a grasping deficit, most commonly an inability to actively open the hand. This motor impairment significantly impacts daily activities, social interactions, professional life, and overall quality of life. Despite numerous treatments available in rehabilitation centers during the subacute phase, no functional assistive devices are currently usable at home. Since 2018, our team, in collaboration with the CAMIN-INRIA team, has developed a Grasp Neuroprosthesis (GNP). This device uses functional electrical stimulation to restore grasping function in hemiplegic subjects, enhancing autonomy in daily bimanual tasks. The GNP has been evaluated in hospital settings through two studies, defining preferred control modalities and demonstrating significant functional impact. Additionally, another study tested a wearable version of the GNP used autonomously at home for two months. This study showed the feasibility and functional benefits of home GNP use, provided the device is customizable to the patient's characteristics and environment. Initial results indicate improved quality of life and increased autonomy with GNP use. The wearable GNP consist of a forearm orthosis made of soft fabric, integrating an electrode array and a stimulator (CE medical marking for home use), connected via WiFi to a microprocessor positioned in a pouch. The microprocessor incorporates information from inertial measurement units and a microphone, allowing the user to control the electrical stimulator on demand. The stimulation targets the extensor muscles of the long fingers and the thumb, enabling the user to open the hand on demand. We propose extending the home use of the GNP to two patients for one year. Each subject will be followed for one year, with evaluations in a hospital setting at the beginning and end of the period, monthly follow-ups at home throughout the year, and on-demand video consultations.

The goal of this clinical study is to examine the effectiveness of the Cognitive Orientation to daily Occupational Performance (CO-OP) in adults (18+) with accuired brain injury when applied in Danish rehabilitation context. The primary research question is: What is the effectiveness of the CO-OP approach on improvement of performance of daily activities (ADL) and quality of life compared to usual rehabilitation practice. Participants in the intervention group will recieve the CO-OP intervention as part of their rehabilitation in the following phases: Initial phase: Goalsetting is mandatory and based on the participant's prioritized ADL performance issues identified in their baseline COPM. Education phase: Individual education in the metacognitive Goal-Plan-Do-Check strategy. Training phase: CO-OP training that involves repetitive use of the Goal-Plan-Do-Check for problem solving and skill acquisition. The therapist employs dynamic performance analysis and guided discovery to help participants understand performance issues and formulate plans for achieving their goals. Participants then execute and evaluate these plans, with a focus on developing domain-specific cognitive strategies. The therapist actively encourages generalization and transfer of skills. Homework is mandatory. Participants in the control group will recieve usual rehabilitation practice in the following phases: Initial phase: Goalsetting is optional and may be based on previous assessment or on a conversation with the participant. Training phase: Different approaches may be taken such as observation and practice of activities or consultation about performance issues and how participants may deal with them. The therapist may guide the participant's performance verbally, physically or trough picture materials. Homework may be included.

The CLAAS® device will be evaluated for safety and efficacy by establishing its performance is non-inferior to the commercially available WATCHMAN® and Amulet™ left atrial appendage closure devices in patients with non-valvular atrial fibrillation. Patients who are eligible for the trial will be randomized to receive either the CLAAS device or the WATCHMAN or Amulet™ devices and will be followed for 5 years after device implant.

This RCT will determine the effects of attention focus training which is a comprehensive intervention to improve cognitive outcomes. Attention is one of the major cognitive outcome and problems with attention can deteriorate the quality of life of people suffering from stroke. Intervention will be provided for 4 weeks. Outcomes will be assessed at baseline and after provision of intervention.

The aim is to compare the rate of hypertensive subjects with ICH who reach SBP target with stability within 60 minutes of enrollment, among patients treated with IV clevidipine with those treated with alternate IV antihypertensive regimen.

The primary objective of this study is to evaluate the effectiveness (prevention of thromboembolic events) and safety (major bleeding) of adding oral anticoagulation (OAC) to background antiplatelet therapy in patients who develop new-onset post-operative atrial fibrillation (POAF) after isolated coronary artery bypass graft (CABG) surgery. All patients with a qualifying POAF event, who decline randomization, will be offered the option of enrollment in a parallel registry that captures their baseline risk profile and their treatment strategy in terms of anticoagulants or antiplatelets received. These patients will also be asked to fill out a brief decliner survey.
