Ketogenic Diet to Improve Neuro-recovery

The purpose of this project is to determine if 5 weeks of ketogenic (KD, high-fat) diet vs. standard diet (SD) significantly improves motor and sensory function, glycemic function, and functional independence in patients with spinal cord injury.

Spinal Cord Stimulation Assisted by Motor Rehabilitation Training for Restoring Motor Function After Spinal Cord Injury

Interventional prospective longitudinal on the evaluation of spinal cord stimulation (SCS) assisted by motor rehabilitation training for restoring motor function in patients with spinal cord injury (SCI). The investigators will enroll ten research participants with clinically incomplete/complete SCI (patients with paraplegia or severe paraparesis) who will undergo SCS subsequently assisted by motor rehabilitation training for restoring motor function at IRCCS Ospedale San Raffaele, Milan, Italy. The main goal of the project is to evaluate the improvement in motor function generated by the combination of SCS and locomotor training. In line with recently published studies, the investigators propose that daily locomotor training in the presence of SCS with continuous stimulation parameters setting will enable the SCI individuals to stand and step independently while bearing full weight.

TTNS in SCI Patients With Neurogenic Detrusor Overactivity

This is a prospective, single-arm, pilot study to assess effectiveness and tolerability of transcutaneous tibial nerve stimulation (TTNS) in managing neurogenic detrusor overactivity in spinal cord injury patients. 12 - 16 spinal cord injury patients with neurogenic detrusor overactivity will be recruited. The intervention includes administration of TTNS at the highest tolerated level for 20 minutes daily for 4 weeks, using a neuromodulation device -- Tensi+. Outcome measures including Urodynamic Study (UDS) will be retrieved or collected at baseline and collected after the 4 weeks of TTNS administration. Other outcome measures include Overactive Bladder Questionnaire Short Form (OAB-Q-SF), which will be administered before and after TTNS administration, subject's level of discomfort and any adverse events experienced by the subject will be recorded after each intervention session and a bladder diary will be recorded weekly for subjects not on indwelling urinary catheters. A TTNS satisfaction survey will also be performed at the end of the study.

Transcutaneous Tibial Nerve Stimulation for Spinal Cord Injury Neurogenic Bladder

The purpose of this study is to determine if electric stimulation to the leg, called transcutaneous tibial nerve stimulation (TTNS), can improve bladder outcomes in acute spinal cord injury.

Effects of a Mobile App-Based Mindfulness Intervention in Persons With Spinal Cord Injury and Chronic Pain

The purpose of this study is to evaluate the efficacy of a 6-week app-guided MM intervention compared to a 6-week app-guided health education AC condition on pain intensity, pain interference, depression, and anxiety.

cHAnging the Perceived Pain INtensity in divErSe Populations With Spinal Cord Injury

Chronic neuropathic pain affects 69% of adults with spinal cord injury (SCI). Current treatment options are limited (primarily pain medications) with insufficient benefits and significant risks for addiction and adverse effects. Of the available mind and body approaches, Qigong is the most accessible for adults with SCI with evidence for effectiveness in reducing pain, but there is insufficient evidence to make recommendations for adults with SCI. Thus, the feasibility of Qigong in SCI needs to be established. To support our feasibility study, we investigated a 12-week remote Qigong program in adults with SCI and neuropathic pain. We recruited 23 adults with SCI, 18 completed the study, and 12 completed the 1-year follow-up. They practiced Qigong 138% of the required intensity (which was, at least 3x/week with Qigong video through the internet). Their pain was reduced by 44% after 12 weeks of Qigong practice and was still reduced at the 6-week and 1-year follow-up. However, three key elements need to be addressed before performing a larger effectiveness study: (1) feasibility/acceptability of Qigong from adults with SCI of diverse backgrounds; (2) feasibility of the study design with control group); and (3) objective outcome measures. This R34 feasibility study, the HAPPINESS trial (cHAnging the Perceived Pain INtensity in divErSe populations with Spinal cord injury), will expand on our prior study to consolidate feasibility with a rigorous protocol. We will address the following aims: AIM 1. Identify the facilitators/barriers to participating in a Qigong study through focus groups/interviews with stakeholders from diverse backgrounds, defined as Hispanics, veterans, and adults living in rural, underserved areas. AIM 2. Establish the feasibility of study design/methods of the HAPPINESS trial in adults with SCI (at least 50% of diverse backgrounds) through pre-specified targets for recruitment/enrollment, feasibility, and acceptability of design and outcomes. Using a Phase I randomized controlled trial design, 40 adults with SCI-related neuropathic pain will be randomized to 12-week remote Qigong intervention OR a short daily pain management survey that can be completed on phone/iPad/computer + 6-month follow-up. The study results will facilitate a rigorous structure to design larger effectiveness studies and facilitate a clear pathway for researchers to investigate Qigong and other mind-body approaches for whole-person health in diverse groups of adults with chronic/neurological disorders.

Closed-loop Spinal Stimulation for Restoration of Upper Extremity Function After Spinal Cord Injury

The purpose of this study is to assess the efficacy of non-invasive (transcutaneous) closed-loop electrical spinal cord stimulation for recovery of upper limb function (Aim 1) and spasticity (Aim 2) following spinal cord injury.

Transspinal Stimulation Plus Locomotor Training for SCI

Locomotor training is often used with the aim to improve corticospinal function and walking ability in individuals with Spinal Cord Injury. Excitingly, the benefits of locomotor training may be augmented by noninvasive electrical stimulation of the spinal cord and enhance motor recovery at SCI. This study will compare the effects of priming locomotor training with high-frequency noninvasive thoracolumbar spinal stimulation. In people with motor-incomplete SCI, a series of clinical and electrical tests of brain and spinal cord function will be performed before and after 40 sessions of locomotor training where spinal stimulation is delivered immediately before either lying down or during standing.

Mild Intermittent Hypoxia: A Prophylactic for Autonomic Dysfunction in Individuals With Spinal Cord Injuries

The prevalence of autonomic dysfunction and sleep disordered breathing (SDB) is increased in individuals with spinal cord injury (SCI). The loss of autonomic control results in autonomic dysreflexia (AD) and orthostatic hypotension (OH) which explains the increase in cardiovascular related mortality in these Veterans. There is no effective prophylaxis for autonomic dysfunction. The lack of prophylactic treatment for autonomic dysfunction, and no best clinical practices for SDB in SCI, are significant health concerns for Veterans with SCI. Therefore, the investigators will investigate the effectiveness of mild intermittent hypoxia (MIH) as a prophylactic for autonomic dysfunction in patients with SCI. The investigators propose that MIH targets several mechanisms associated with autonomic control and the co-morbidities associated with SDB. Specifically, exposure to MIH will promote restoration of homeostatic BP control, which would be beneficial to participation in daily activities and independence in those with SCI.

Brain-Controlled Spinal Stimulation Walking Therapy After Incomplete Spinal Cord Injury (SCI)

The purpose of this research is to test the effectiveness of a new therapy, called Brain-Computer Interface (BCI)-Transcutaneous Spinal Cord Stimulation (TSCS), for improving walking in people with an incomplete spinal cord injury (SCI).

MUSic Therapy In Complex Specialist Neurorehabilitation

Aim: Investigate whether patients undergoing specialist rehabilitation after complex neurological injury show different functional outcomes if music therapy is included in their rehabilitation program compared to usual care. Background: Patients with complex needs following a brain, spinal cord, and/or peripheral nerve injury often require a period of specialist neurorehabilitation. This involves multiple therapy disciplines, led by a Consultant in Rehabilitation Medicine, Neurology, or Neuropsychiatry. Although music therapy is suggested to enhance neuroplasticity and recovery in patients with brain injury, it is not routinely commissioned in clinical care due to a lack of supportive evidence. Hypothesis: Patients undergoing music therapy in addition to complex specialist rehabilitation show better functional outcomes compared to usual care. Number of participants: 75, aged 16-80 years. Methods: Patients undergo baseline assessments and are randomised to MUSIC or CONTROL Therapy. Both arms receive 1-3 additional therapy sessions per week, matched for duration and number, total 15 hours. After approximately 10-weeks intervention, assessments are repeated. All participants then have access to music therapy until they are discharged from Neurorehabilitation Unit (NRU), with additional qualitative data collection using semi-structured interviews, field notes, staff reports, staff stress surveys, and broader ecological observations. Duration for Participants: From consent to discharge from NRU. Primary Outcome: Change in Functional Independence Measure+Functional Assessment Measure (FIM+FAM), Northwick Park Dependency Scale (NWPDS), and Barthel Activities of Daily Living pre and post 15 hours intervention. Secondary Outcome: Change in quality of life (Flourishing Scale), psychological distress (Hospital Anxiety and Depression Scale, Depression Intensity Scale Circles), social interaction (Sickness Impact Profile Social Interaction Subscale), well-being (WHO Well-Being Index), and communication (Communication Outcomes After Stroke Scale), pre and post 15 hours intervention. Mean difference in well-being (WHO Well-Being Index) throughout the intervention period between music therapy and control therapy groups. Mean difference in post-intervention pain and mood visual analogue scores between music therapy and control therapy groups.

Closed-loop Deep Brain Stimulation to Treat Refractory Neuropathic Pain

Deep brain stimulation (DBS) holds promise as a new option for patients suffering from treatment-resistant chronic pain, but current technology is unable to reliably achieve long-term pain symptom relief. A "one-size-fits-all" approach of continuous, 24/7 brain stimulation has helped patients with some movement disorders, but the key to reducing pain may be the activation of stimulation only when needed, as this may help keep the brain from adapting to stimulation effects. By expanding the technological capabilities of an investigative brain stimulation device, the investigators will enable the delivery of stimulation only when pain signals in the brain are high, and then test whether this more personalized stimulation leads to reliable symptom relief for chronic pain patients over extended periods of time.

Reduction of Opioid Dose Using Conditioning & Open-Label Placebo (COLP) in Intensive Rehabilitation

The use of conditioning open-label placebo (COLP) will be studied as a dose extension method to lower opioid dosage in patients with spinal cord injury, polytrauma, and burn injury. The goal is to provide the same level of pain relief with a reduced opioid dose to diminish adverse effects as well as the risk of addiction associated with narcotic treatment.

Closed-Loop Deep Brain Stimulation for Refractory Chronic Pain

Chronic pain affects 1 in 4 US adults, and many cases are resistant to almost any treatment. Deep brain stimulation (DBS) holds promise as a new option for patients suffering from treatment-resistant chronic pain, but traditional approaches target only brain regions involved in one aspect of the pain experience and provide continuous 24/7 brain stimulation which may lose effect over time. By developing new technology that targets multiple, complimentary brain regions in an adaptive fashion, the investigators will test a new therapy for chronic pain that has potential for better, more enduring analgesia.

Temporary Inactivation of Strong Muscle Sensation to Improve Rehabilitation Interventions in SCI

The investigators are conducting a research study to try to improve rehabilitation interventions for individuals with spinal cord injury (SCI). In this study, the aim is to determine if temporarily numbing non-paralyzed arm muscles with an over-the-counter numbing cream while exercising paralyzed muscles, can improve the strength, function, and sensation of paralyzed muscles after a spinal cord injury.

ZEPU-AI3 Lower Limb Feedback Robot Training Study

Lower limb motor dysfunction resulting from stroke, spinal cord injury, or other neurological disorders substantially limits mobility, independence, and quality of life. Robotic rehabilitation has emerged as a promising approach to provide intensive, repetitive, task-oriented training. The ZEPU-AI3 Lower Limb Feedback Training and Evaluation Robot is designed to deliver interactive lower limb training while providing real-time performance feedback. This pilot randomized controlled trial aims to evaluate the safety, efficacy, and feasibility of ZEPU-AI3-assisted rehabilitation combined with conventional rehabilitation compared with conventional rehabilitation alone in patients with lower limb motor dysfunction. The primary outcomes include safety, feasibility, and changes in lower limb motor function, gait performance, and functional mobility. The findings will provide preliminary evidence to support future large-scale clinical trials and the implementation of robotic rehabilitation in clinical practice.

Brain Controlled Spinal Cord Stimulation In Participants With Spinal Cord Injury For Lower Limb Rehabilitation

The purpose of this clinical study is to evaluate the preliminary safety and effectiveness of using a cortical recording device (ECoG) combined with lumbar targeted epidural electrical stimulation (EES) of the spinal cord to restore voluntary motor functions of lower limbs in participants with chronic spinal cord injury suffering from mobility impairment. The goal is to establish a direct bridge between the motor intention of the participant and the the spinal cord below the lesion, which should not only improve or restore voluntary control of legs movement and support immediate locomotion, but also promote neurological recovery when combined with neurorehabilitation.

Optimization of Adaptive Rowing Seating

Adaptive sports programs are integral components to combating Veteran isolation, promoting wellbeing and seeking to build teams, networks, communities. These activity-based communities are medicine free treatment systems enhancing Veterans' health from a holistic perspective. This approach to Veteran healthcare is critical as studies indicate Veterans not only have 56% higher perceived social isolation but are also 1.5x more susceptible to suicide than the general public. It is imperative to improve access to exercise and physical activity through adaptive sport or recreation. This proposal is going to focus on Adaptive Indoor Rowing for Veterans with limited or changing trunk stability (i.e. SCI/D, paralysis, paresis, etc.). Rowing is a unique full-body activity that increases cardiovascular demand and increases coordination and aerobic capacity through movement. This proposal aims to address critical gaps in adaptive rowing technology and provide Veterans with limited trunk stability access to full stroke adaptive rowing.

Targeted HD-tDCS to Improve Upper Limb Rehabilitation in SCI

The proposed project seeks to maximize the functional recovery achieved during the rehabilitation of the paretic upper limbs in individuals with SCI. The investigation will work towards optimizing the use of transcranial direct current stimulation (tDCS), an adjunct known to improve the effectiveness of rehabilitation. In particular, the relationship between the specificity of current delivery and functional benefit will be explored, and findings may lead to a framework that can be translated to the clinic setting.

Epidural Electrical Stimulation for Spinal Cord Injury Patients and Corticospinal Motor Circuit Improvement

The study aims to examine the plausible interventional mechanisms underlying the effects of epidural spinal cord stimulation.

Spinal Neurorehabilitation for Veterans With SCI

Chronic spinal cord injury (SCI) is a debilitating disorder in Veterans and the broader U.S. population that does not have a cure. Veterans with severe SCI demonstrate permanent loss of sensory and motor function below their injury resulting in decreased quality of life and independence. Recently, electrical spinal neuromodulation has emerged as a potential approach to restore voluntary motor function and locomotion in persons with chronic SCI. However, spinal neuromodulation has yet to translate to clinical use due to small sample sizes in research studies and a lack of information on which patients would benefit. Here, the investigators propose a novel approach to evaluate the priorities and barriers faced by Veterans with SCI to use spinal neuromodulation, understand the neural connections remaining in Veterans with severe SCI, and determine potential functional improvements using non-invasive spinal neuromodulation technology. This research represents the first step towards deploying techniques that could dramatically improve function and quality of life for Veterans with SCI.

Epidural and Dorsal Root Stimulation in Humans With Spinal Cord Injury

A study to compare electrophysiologic activity of epidural stimulation and dorsal root ganglion stimulation, as well as quantify changes in motor performance with both types of stimulation over the course of 10 rehabilitation sessions.

SCED Myokines and Cognition in SCI

Rationale: Individuals with spinal cord injury (SCI) suffer from accelerated cognitive aging. In able-bodied individuals, a vast amount of studies have shown that exercise interventions can improve cognitive function. Myokines (i.e. factors released into the blood stream from muscle cells) are considered one of the mediators of this beneficial effect. Neuromuscular electrical stimulation (NMES), used to replace or support muscle training in disabled individuals with poor exercise possibilities, was shown to elicit a large release of myokines (in some studies larger than following voluntary exercise). However, so far, the effects of NMES on cognitive function have never been studied before. In fact, only one study has previously investigated the effect of exercise on cognitive function in persons with SCI. Objective: The primary aim is to assess to what extent a 12 week intervention with NMES to the quadriceps muscles of people with SCI can change their performance on a set of cognitive tests. Secondarily, the investigators will measure to what extent NMES to the quadriceps muscles of people with SCI induces changes in blood levels of the myokine brain-derived neurotrophic factor (BDNF), which is considered a potential mediator of the exercise-cognition effect, facilitating neuroplastic processes. Study design: A single case experimental design (SCED) with sequential multiple baseline time series and a single-armed prospective study design, with a random duration of the baseline phase ranging from 3 to 6 weeks, an intervention phase of 12 weeks, and a 12 week period without measurements, followed by a follow-up phase of 3 weeks; in addition to a single-armed prospective study design. Study population: Individuals (n = 15) aged 18 years and older with a chronic SCI (\>1y post-injury) and with visible or palpable contraction of the quadriceps muscles upon NMES will be recruited at the rehabilitation centre of Adelante in Hoensbroek, the Netherlands. Intervention: The study participants will receive 30min of NMES using surface electrodes on the quadriceps muscles three times per week for a total duration of 12 weeks. Main study parameters/endpoints: The primary outcome is cognitive function changes which will be measured using a secured smartphone application (e.g. m-Path). Secondary outcome measures are changes in the blood myokine levels of BDNF and changes in cognitive outcome scores on an verbal cognitive test battery.

Combined Magnetic Stimulation and Ultrasound for Detrusor Overactivity in SCI

This clinical trial aims to investigate whether the combination of high-frequency sacral nerve root magnetic stimulation and bladder-directed ultrasound therapy can effectively improve detrusor overactivity (involuntary bladder contractions) and related voiding dysfunctions in patients with spinal cord injury. The main questions it seeks to answer are: What is the effect of high-frequency sacral nerve root magnetic stimulation on detrusor overactivity and bladder function in patients with spinal cord injury? What is the effect of bladder-directed ultrasound therapy on detrusor overactivity and bladder wall compliance in patients with spinal cord injury? Is the combination of these two treatment modalities superior to magnetic stimulation alone?
