SCI - Spinal Cord Injury

The purpose of this study is to test a strategy to potentiate functional recovery of lower limb motor function in individuals with spinal cord injury (SCI). The FDA approved drug, Dalfampridine (4-AP). 4-AP will be used twice-daily in combination of Spike-timing-dependent plasticity (STDP) stimulation and STDP stimulation with limb training.

The goal of this prospective, open-label cohort study is to assess functional outcomes in individuals with cervical spinal cord injury who have undergone nerve transfer surgery to restore upper limb function. The main questions it aims to answer are: * Does nerve transfer improve hand function in individuals with cervical spinal cord injury? * What factors are associated with functional improvement following nerve transfer? Researchers will compare functional outcomes at 24 months post-surgery to 1) baseline outcomes and 2) individuals with cervical spinal cord injury who did not undergo nerve transfer. Participants who have received nerve transfer surgery as part of their regular medical care will complete functional hand tests, electrodiagnostic assessments, and questionnaires on independence and mood every 3 months for 24 months after surgery.

Test the feasibility of using electrocorticography (ECoG) signals to control complex devices for motor and speech control in adults severely affected by neurological disorders.

The study is designed to investigate the effects of passive heat therapy on blood vessel health in 40 people (48 enrolled with attrition rate of 20%). Following an extensive set of vascular function tests, participants will engage in either a passive heat therapy intervention for 60 minutes, 4 times a week for 8 weeks, or a placebo intervention at a lower temperature. Seven of the 8 weeks of intervention will occur in the home setting. Vascular function tests will be repeated after the 8 weeks to determine if chronic passive heat stress improved vascular health.

The purpose of this research is to explore the effect of magnetic stimulation to activate the brain, electrical spinal cord stimulation to activate spinal cord, and electrical muscle stimulation used to activate upper limb (arms), lower limb (legs) and trunk (stomach) muscles in people with spinal cord injury (SCI) and able-bodied subjects (without SCI).

The purpose of this research is to determine the effects of food on cardiovascular and metabolic health in men with and without spinal cord injury (SCI).

This study will evaluate the long-term effect of chronic spinal cord stimulation to restore volitional movement for patients with chronic spinal cord injuries.

This clinical trial aims to evaluate the safety and efficacy of spinal cord stimulation (SCS) in treating patients with urinary and bowel dysfunction after spinal cord injury (SCI). SCI is a highly disabling condition that can lead to sensory, motor, and autonomic nervous system dysfunction below the injury level. Neurogenic bladder and bowel dysfunction are common sequelae of SCI, seriously affecting patients' quality of life. Currently, clinical treatments can only partially alleviate urinary and bowel dysfunction, and more effective therapeutic approaches are still needed. Existing clinical studies have shown that SCS is gradually being applied to treat neurogenic bladder and bowel dysfunction in SCI patients. SCS can significantly improve urinary efficiency, bladder capacity, compliance, and detrusor pressure in SCI patients, thereby enhancing their quality of life. The main questions this study aims to answer include: 1. Can this protocol help patients restore partial urinary and bowel function? 2. Besides the restoration of partial urinary and bowel function , can the SCS therapy could also help patients to restore the walking function. Patients with urinary and bowel dysfunction more than 6 months after spinal cord injury will undergo epidural spinal stimulation electrode implantation surgery two weeks after functional assessment. Then the parameter optimization and rehabilitation will last for 6 months. The follow-up records and assessments will be conducted monthly at 2, 4, and 6 months after surgery.

The goal of this clinical trial is to investigate the effect of a muscle-mimicking, fabric-type shoulder orthosis on functional movements of the upper limb in patients with neuromuscular disorder. The main questions it aims to answer are: * What is the impact of the muscle-mimicking, fabric-type shoulder orthosis on upper limb functional movements in patients with neuromuscular disorder? * Are there observable differences in upper limb function when the shoulder orthosis is worn versus when it is not? Participants will: * Receive education on how to wear and use the shoulder orthosis. * Undergo evaluations, including assessment of upper limb performance, shoulder muscle strength testing, active range of motion measurements, assessment of functional workspace, goal attainment scale evaluation, surface electromyography, physiological measurements such as blood pressure and heart rate, fatigue assessment, and assessment for any musculoskeletal or skin-related issues. Researchers will compare neuromuscular disorder patients before and while wearing and operating the shoulder orthosis to see if there are any significant effects on variables such as upper limb function, range of motion, functional workspace, goal attainment scale, and surface electromyography.

Identify the extent to which personalization through a large language model (LLM) affects communication. 6. Identify the appropriate capabilities to enable through an agentic communication interface. Key measures include: ITR - information transfer rate SUS - system usability scale

The primary objective of this clinical trial is to investigate the efficacy of motor imagery-based brain-computer interface (MI-BCI) technology in improving motor function among patients with spinal cord injury (SCI), as well as its impact on cortical motor area function across varying states. To achieve this, the study will implement MI-BCI intervention in SCI patients, evaluate post-treatment motor function improvements, and assess changes in cortical motor area oxygen metabolism (via functional near-infrared spectroscopy, fNIRS) and neural activity (via electroencephalography, EEG). The ultimate goal is to establish a novel rehabilitation strategy for SCI. Specifically, the trial aims to: (1) determine whether MI-BCI effectively enhances motor function in SCI patients; and (2) clarify the differential effects of MI-BCI on cortical motor area function under distinct states (e.g., resting vs. task-performing) in this population. Participants will be randomly assigned to one of two groups: the experimental group will undergo MI-BCI training, while the control group will receive active cycling training (as a conventional rehabilitation control). Both interventions will be structured as 20-minute sessions, administered 5 days per week, over a total of 4 weeks.Pre- and post-treatment assessments will include: lower limb motor function (measured by the Lower Limb Motor Score), activities of daily living (evaluated via the Modified Barthel Index), walking capacity (quantified using the Spinal Cord Injury Walking Index), and cortical motor activity (captured through fNIRS and EEG measurements).

The overall objective is to obtain an assessment of the pharmacokinetics of \[18F\]3F4AP in healthy volunteers and subjects with demyelinating diseases such as mild cognitive impairment (MCI), Alzheimer's Disease (AD), Multiple Sclerosis (MS), Spinal Cord Injury (SCI) and Spinal radiculopathy (SR).

The purpose of this study is to understand how standing and sitting balance control is altered after spinal cord injury and how a new type of robotic assistive device may be used with spinal stimulation to improve muscle function. The investigators will be testing a device called the Tethered Pelvic Asist Device (or "TPAD") in this study. The TPAD may be helpful in two ways. It can be used to help control and support of the trunk, pelvis, and knees during stand training. Also, the TPAD can be used as a training tool by providing controlled "pushes" or "perturbations" that must be corrected by the person with spinal cord injury in order to maintain proper posture and upright balance. This could be helpful for improving muscle function after spinal cord injury. Participants will be placed into one of two groups based on availability and preference. Group 1 will receive TPAD training with stimulation and assessments with and without stimulation. Participation in this group lasts approximately 4 months. Group 2 will only receive assessments with and without stimulation. Participation in this group last approximately 3 weeks.

The purpose of this study is to investigate how standing and sitting balance control is altered after spinal cord injury (SCI) and how a new type of robotic assistive device may be used to improve muscle function. This device is called the Tethered Pelvic Assist Device, or TPAD. The main aims are to: 1\. Examine muscle activation patterns generated during different types of standing in spinal cord injured individuals using robotic assistance or self-assistance for balance 2 and 3. Examine the effectiveness of robotic-assisted stand training in the improvement of posture control during different types of standing and sitting in spinal cord injured individuals. Participants will be placed into one of 5 groups based on a physical classification of their spinal cord injury: Group 1: * Individuals with SCI that can stand independently * Will receive TPAD training * Will undergo standing, posture, sitting, and stepping assessments * Participation in this group will last about six months Group 2: * Individuals with SCI that cannot stand independently * Will receive TPAD training * Will undergo standing, posture, sitting, and stepping assessments * Participation in this group will last about 6 months Group 3: * Individuals with SCI that can stand independently * Will undergo standing and posture assessments * Participation in this group will last about 2 weeks Group 4: * Individuals with SCI that cannot stand independently * Will undergo standing and posture assessments * Participation in this group will last about 2 weeks Group 5: * Individuals without a SCI * Will undergo standing, posture, and sitting assessments * Participation in this group will last about 2 weeks

This clinical trial explores the effectiveness of transcutaneous spinal cord stimulation (tSCS), a non-invasive technique, in facilitating spinal circuitry adaptation in individuals with spinal cord injury (SCI). While epidural spinal cord stimulation (eSCS) has shown functional benefits, its application is limited by the side effects associated with implanted electrodes. tSCS, which shares a similar mechanism but does not require surgery, has yet to be extensively studied in large human trials. The study aims to: Determine optimal tSCS parameters for non-invasive spinal stimulation. Investigate the priming effect of tSCS on spinal circuitry during machine-assisted ankle movement training. Examine the long-term clinical outcomes of combining tSCS with ankle movement training in individuals with incomplete SCI. The trial will include both healthy participants and individuals with complete and incomplete SCI, using the soleus post-activation depression (PAD) model to evaluate spinal circuitry adaptation. The results will provide insights into spinal re-adaptation and potentially introduce a novel, non-invasive approach for SCI rehabilitation.

Spasticity and rigidity are common symptoms of central nervous system injuries, such as spinal cord injury and Parkinson's disease, and result in distinct patterns of increased resistance during passive joint movements. Spasticity is characterized by a velocity-dependent increase in stretch reflexes, accompanied by exaggerated tendon responses, while rigidity is marked by consistent resistance throughout the range of motion, traditionally considered independent of stretch velocity. However, recent studies suggest that rigidity may also be influenced by stretch velocity. This study aims to investigate muscle tone by examining spasticity, rigidity, and normal muscle function through neural and biomechanical changes. Standard clinical tools, such as the Modified Ashworth Scale and Unified Parkinson's Disease Rating Scale, along with additional assessments like the Myoton and Post-Activation Depression (PAD), will be employed.

Current forms of pharmacologic and non-pharmacologic treatments for hypotension and orthostatic hypotension (OH) remain inadequate during acute inpatient rehabilitation (AIR) following a traumatic spinal cord injury (SCI). A critical need exists for the identification of safe, practical, and effective treatment options that stabilize blood pressure (BP) after traumatic SCI. Recent published evidence suggests that transcutaneous Spinal Cord Stimulation (TSCS) can be used to raise seated BP, and mitigate the falls in BP during orthostatic repositioning in individuals with chronic SCI. This site-specific project will focus on the use of TSCS to stabilizing seated BP and mitigate the fall in BP during orthostatic repositioning during AIR following traumatic SCI.
