Longitudinal Autonomic Characterization as a Predictor for Secondary Medical Complications Post-SCI

The purpose of this research is to learn about how the body is able to balance changes in blood pressure, how that changes over time, and how these changes impact a participant's risk of developing medical problems.

Deciphering Preserved Autonomic Function After Spinal Cord Injury

This study looks to characterize gradients of dysfunction in the autonomic nervous system after spinal cord injury. The autonomic nervous system plays key roles in regulation of blood pressure, skin blood flow, and bladder health- all issues that individuals with spinal cord injury typically suffer. Focusing on blood pressure regulation, the most precise metric with broad clinical applicability, the investigators will perform laboratory-based tests to probe the body's ability to generate autonomic responses. For both individuals with spinal cord injury and uninjured controls, laboratory-based experiments will utilize multiple parallel recordings to identify how the autonomic nervous system is able to inhibit and activate signals. The investigators anticipate that those with autonomic dysfunction after spinal cord injury will exhibit abnormalities in these precise metrics. The investigators will further have research participants wear a smart watch that tracks skin electrical conductance, heart rate, and skin temperature, which can all provide clues as to the degree of autonomic dysfunction someone may suffer at home. The investigators will look to see if any substantial connections exist between different degrees of preserved autonomic function and secondary autonomic complications from spinal cord injury. In accomplishing this, the investigators hope to give scientists important insights to how the autonomic nervous system works after spinal cord injury and give physicians better tools to manage these secondary autonomic complications.

The Impact of Injustice Appraisals on Psychosocial Outcomes Following Spinal Cord Injury: A Longitudinal Study

The primary objectives of this study are to: (1) determine the longitudinal course and impact of injury-related injustice appraisals among civilians and Veterans who have recently acquired a spinal cord injury (SCI), and (2) use qualitative inquiry to gain a rich, contextual understanding of appraisals of injustice during the first year after acquired SCI. The long-term goal of this research is to inform the development of new treatment approaches targeting appraisals of injustice.

Pain Phenotyping in Patients With Neuropathic Pain After Spinal Cord Injury

The development of neuropathic pain is one of the most debilitating sequels after a spinal cord injury (SCI). The overall aim of this study is to investigate potential underlying pathophysiological mechanisms of neuropathic pain after SCI. The functionality of the nociceptive pathway in humans as well as its plastic changes following SCI will be inferred with sophisticated sensory and pain phenotyping using quantitative sensory testing (i.e., psychophysical measures), objective neurophysiological measures of pain processing and the recording of pain-related autonomic responses (i.e., galvanic skin response, cardiovascular measures and pupil dilation). In addition, the interplay between the somatosensory and autonomic nervous system and its association with the development and maintenance of neuropathic pain after SCI will be investigated.

Exploring the Effect of Mindfulness on Quality of Life (QoL) in Spinal Cord Injury (SCI)

The purpose of this study is to determine if practicing mindfulness breathing exercises has an effect on the overall health of persons with SCI

Improving Adherence to Spinal Cord Injury Exercise Guidelines Using Smartphone Technology and E-coaching

The goal of this research is to increase physical activity among individuals with a spinal cord injury (SCI) through a customized, interactive smartphone-based health app and e-coaching using three phases: (1) leading focus groups of potential app users and clinicians to gain information regarding health apps preferences for optimal consumer use, (2) conducting a usability study of the customized app to determine the quality and implement further changes for optimization, and (3) conducting a sequential multiple assignment randomized trial (SMART) to determine the most effective adaptive intervention to improve exercise adherence. A SMART trial will be used to determine when and how to adapt dosage, timing, and delivery to increase adherence and address low-response behaviors. In Stage-I, the investigators will compare outcomes among participants using a generic, non-interactive exercise app (Group 1) to a customized, interactive app that can gain information through frequent Ecological Momentary Assessments (EMA) that will be used to modify each participant's exercise programs (Group 2). After 12 weeks, participants who are not meeting the exercise guidelines at least 50% of the time will also be asked to participate in motivational interviewing-based e-coaching either two or four times per month in addition to their originally assigned intervention (Stage-II). By completing these three phases, this project addresses deficiencies in exercise levels and compliance by implementing an individualized exercise prescription, an adaptive intervention for low responders, a way to address barriers to exercise, and a free smartphone app for broad implementation.

Nomad P-KAFO Study

The goal of this clinical trial is to evaluate the impact of using the Nomad powered KAFO in people who have had a musculoskeletal or neurological injury that has affected their ability to walk. The main questions it aims to answer are to quantify the effectiveness of the Nomad in improving mobility, balance, frequency of falls, and quality of life in individuals with lower-extremity impairments compared to their own brace, over three months of daily home and community use. Participants will: * Wear a sensor that records everyday activities and mobility. * Perform measures of mobility and different activities of participation using their own brace. * Perform measures of mobility and different activities of participation using the Nomad powered KAFO

ARC-IM System to Manage Symptomatic Blood Pressure Instability Secondary to Chronic Spinal Cord Injury

Empower BP is a pivotal, interventional, multicenter, prospective, randomized, controlled double-blinded study to evaluate the safety and effectiveness of the ARC-IM System in managing symptomatic blood pressure instability in individuals with chronic SCI (\>1 year after SCI). The primary effectiveness outcome will be evaluated through subject-reported ADFSCI and seated blood pressure assessments at 3 months post-implant. Following a baseline screening period and the surgical implantation of the ARC-IM System, subjects will be randomized with a 2:1 ratio into an active or control arm for 3 months. All the subjects will undergo therapy activation sessions (into either Group 1: active intervention, or Group 2: intervention aimed to mimic the active intervention without the active component) within 21 days of the surgical implant and will then commence independent at-home use of ARC-IM Therapy. At the 3 Month timepoint, after all assessments are conducted, all subjects will transition to the open-label period in order to receive the active version of the ARC-IM System in an open-label fashion. All subjects will undergo therapy programming sessions following Month 3.

Transcutaneous Spinal Cord Stimulation Combined With Arm Bike for Cardiovascular Recovery in SCI

Spinal cord injury (SCI) can make it hard for the body to self-regulate some of its automatic functions like blood pressure, breathing, and heart rate. This can also make it hard for those living with SCI to exercise or complete their usual daily activities. The goal of this randomized trial is to test combinatory therapy of moderate arm-crank exercise paired with non-invasive transcutaneous spinal cord stimulation (tSCS) for cardiovascular recovery in adults aged 21-65 following chronic motor-complete spinal cord injury (SCI) at or above the thoracic sixth spinal segment (≥T6). The main questions the study aims to answer are: * Conduct tSCS mapping to determine the most effective location and stimulation intensity for BP control in individuals with motor-complete SCI ≥ T6. * Evaluate the effects 8 weeks of targeted tSCS paired with arm-crank exercise compared to sham stimulation with exercise on improving cardiovascular function in individuals with motor-complete SCI ≥T6. * Evaluate the dosage-response of 8 weeks vs. 16 weeks of targeted tSCS paired with arm-crank exercise on cardiovascular function in individuals with motor-complete SCI ≥T6. * Explore the mechanisms involved in cardiovascular recovery with long-term tSCS paired with arm-crank exercise. Participants will: * Receive either transcutaneous spinal cord stimulation or "sham" spinal cord stimulation while exercising on an arm-crank bicycle in the first 8 weeks. * Come in for approximately 60 visits over a 6-month period. This includes 2, 8-week periods where the investigators will ask participants to come in 3x per week for spinal cord stimulation and exercise. * During assessment visits the researchers will perform a variety of exams including a neurologic, cardiovascular, pulmonary, physical, and autonomic exam, and will ask questions about quality of life and functioning. Assessment procedures also include stool sample and nasal swab collection. Researchers will compare those who receive tSCS and do moderate arm-crank exercise to those who receive a sham stimulation and do moderate arm-crank exercise to see if tSCS is effective at improving cardiovascular and autonomic functioning in those with SCI.

Bacteriophage Therapy in Spinal Cord Injury Patients With Bacteriuria

This is a Phase 1b study to assess the safety, tolerability, PK, and PD of investigational phage therapy (IP) in adults with SCI and bladder colonization (ASB). It is a single-center, randomized, double-blind, placebo-controlled study in adults with SCI with neurogenic bladders and bacteriuria who use indwelling catheters, or who require intermittent catheterization for bladder drainage.

Living Longer and Stronger With Spinal Cord Injury (SCI)

The purpose of this study is to develop a health promotion group intervention to meet the unique health promotion needs of people aging with SCI, to test the efficacy of the adapted intervention program, Living Longer and Stronger with SCI, in a randomized controlled trial and to assess the mechanisms through which the intervention may enhance physical, psychological, and social health.

Locomotor and Bladder Function in Individuals With Acute Spinal Cord Injury

The loss of movement and walking ability significantly affects quality of life after spinal cord injury. In addition, bladder dysfunction consistently ranks as one of the top disorders affecting quality of life after spinal cord injury. The overall objective of this study is to demonstrate that epidural stimulation may be a method for improving stepping, standing and bladder function in individuals with spinal cord injury. With the use of epidural stimulation, the investigators propose to investigate how well the participant can stand and walk and how well the participant's bladder can store or hold urine as well as void or empty urine. The results of this study may aid in the development of treatments to help individuals with spinal cord injuries that are unable to stand or walk and have impaired bladder function.

Hypnotic Cognitive Therapy Reduce Acute & Chronic SCI Pain in Inpatient Rehabilitation

Chronic spinal cord injury (SCI) pain is complex and difficult to treat. For individuals with SCI, pain often begins early in the course of their SCI and continues longitudinally. Unfortunately, SCI-related pain is frequently not responsive to medical treatment and medical treatments that are available and commonly used, such as opioids, have negative side-effects and risk of addiction. Nonpharmacological (non-medication) interventions to reduce chronic pain show promise both for individuals with SCI as well as other chronic pain conditions. Research on psychological interventions for chronic pain over the past two decades has consistently found these interventions to be more effective than no treatment, standard care, pain education, or relaxation training alone. However, many of these interventions are designed and implemented in outpatient settings after chronic pain has already developed. The development of early, effective, and preventative interventions to reduce the development of chronic pain has the potential to vastly improve quality of life for individuals with SCI. Having demonstrated the feasibility and acceptance of this treatment in an earlier study, the purpose of this randomized clinical trial is to compare the treatment of Hypnosis Enhanced Cognitive (HYPCT) therapy to Pain Education (ED) for reducing acute and chronic pain for individuals with new spinal cord injuries. The main goals of the study are to: * Aim 1: Test the effectiveness of HYPCT during inpatient rehabilitation for SCI compared to a ED for reducing current pain intensity. * Aim 2: Determine the post-intervention impact of HYPCT sessions compared to ED on average pain intensity. Participants will be asked to: * Complete 4 surveys over seven months * Complete pre and post treatment pain assessments for each of 4 treatment/control sessions Participants will be assigned to one of two groups for treatment and receive either: * 4 Hypnotic Cognitive therapy sessions or * 4 Pain Education sessions

Design and Delivery Preferences for Exercise Intervention in People With Spinal Cord Injury

This research study aims to explore people's understanding of physical activity behavior and perceptions of what a physical activity program should include for supporting initiation and continuous participation. This study will enroll up to 30 adults (18 or over) with spinal cord injury. The study will use a discrete choice experiment (DCE) design that implements both quantitative (development of preference survey) and qualitative approaches (systematic review; test of preference survey).

Non-invasive BCI-controlled Assistive Devices

Injuries affecting the central nervous system may disrupt the cortical pathways to muscles causing loss of motor control. Nevertheless, the brain still exhibits sensorimotor rhythms (SMRs) during movement intents or motor imagery (MI), which is the mental rehearsal of the kinesthetics of a movement without actually performing it. Brain-computer interfaces (BCIs) can decode SMRs to control assistive devices and promote functional recovery. Despite rapid advancements in non-invasive BCI systems based on EEG, two persistent challenges remain: First, the instability of SMR patterns due to the non-stationarity of neural signals, which may significantly degrade BCI performance over days and hamper the effectiveness of BCI-based rehabilitation. Second, differentiating MI patterns corresponding to fine hand movements of the same limb is still difficult due to the low spatial resolution of EEG. To address the first challenge, subjects usually learn to elicit reliable SMR and improve BCI control through longitudinal training, so a fundamental question is how to accelerate subject training building upon the SMR neurophysiology. In this study, the investigators hypothesize that conditioning the brain with transcutaneous electrical spinal stimulation, which reportedly induces cortical inhibition, would constrain the neural dynamics and promote focal and strong SMR modulations in subsequent MI-based BCI training sessions - leading to accelerated BCI training. To address the second challenge, the investigators hypothesize that neuromuscular electrical stimulation (NMES) applied contingent to the voluntary activation of the primary motor cortex through MI can help differentiate patterns of activity associated with different hand movements of the same limb by consistently recruiting the separate neural pathways associated with each of the movements within a closed-loop BCI setup. The investigators study the neuroplastic changes associated with training with the two stimulation modalities.

AMPLIFY Study: Transcutaneous Spinal Direct Current Stimulation to Enhance Locomotor Rehabilitation After SCI

Locomotor training (LT) facilitates recovery of spinal locomotor networks after incomplete spinal cord injury (ISCI), but walking impairments persist. A limitation of LT is insufficient excitation of spinal locomotor circuits to induce neuroplastic recovery. Transcutaneous spinal direct current stimulation (tsDCS) is a non-invasive approach to increase spinal excitation and modulate spinal reflexes. The study will examine if tsDCS combined with LT enhances locomotor rehabilitation after ISCI.

Heart Rate Variability and Anxiety During Urinary Bladder Catheterization

This is a prospective, randomised study investigating the physical and psychological experience of intermittent catheterization in adult individuals following spinal cord injury (SCI).

Diet and Exercise Solutions to Postprandial Hypotension

The purpose of this study is to determine if a low glycemic diet and lower-body electrical stimulation can reduce postprandial hypotension in individuals with chronic spinal cord injury.

Kinesiophobia, Fear of Falling, Functional Independence, and Psychological Status in Spinal Cord Injury

Individuals aged 18-65 years who have been clinically diagnosed with spinal cord injury and have developed paraplegia will be included in the study. Demographic and clinical data of the participants, including age, sex, height, weight, etiology of injury, level of injury, duration of injury, and comorbidities, will be recorded. In addition, disease-specific characteristics such as ambulation status, wheelchair use, presence of incontinence, and presence and severity of pain will be assessed. Kinesiophobia levels of the patients will be evaluated using the Tampa Scale for Kinesiophobia (TSK). Functional independence will be assessed using the Spinal Cord Independence Measure-III Self-Report (SCIM-III SR). Fall-related concerns will be evaluated using the Spinal Cord Injury-Falls Concern Scale (SCI-FCS). Pain severity will be assessed using the Visual Analog Scale (VAS), and the presence of neuropathic pain will be evaluated using the DN4 Neuropathic Pain Questionnaire. Symptoms related to anxiety and depression will be assessed using the Hospital Anxiety and Depression Scale (HADS). All assessments will be conducted through face-to-face interviews. The collected data will be analyzed to investigate the relationship between kinesiophobia and functional independence, fear of falling, pain, and psychological status in individuals with paraplegic spinal cord injury. Validated Turkish versions of all scales used in the study will be employed.

Upper Extremity Functional Electrical Stimulation (FES) for Restoration of Upper Extremity Function After Spinal Cord Injury (SCI)

The purpose of this research is to examine the effects that functional electrical stimulation (FES) therapy has on the way the arms, brain and spinal cord work. The study team wants to understand what recovery looks like in persons with a spinal cord injury (SCI) or peripheral nerve injury (PNI) using the MyndMove (MyndTec Inc., Ontario, Canada) therapy system. This type of therapy uses stimulation to help people with SCI and other neurological conditions to perform common tasks, work out, or strengthen muscles.
