Spinal cord injury (SCI) often results in severe motor and sensory deficits, leading to significant disability. Preclinical studies and retrospective studies suggest that a critical window of enhanced neuroplasticity may exist immediately after SCI, during which therapeutic interventions could yield greater functional improvements. The impact of time interval since SCI on efficacy of rehabilitation has not been directly assessed and is the focus of this clinical trial.

To expand the variety and number of ligandable proteins for drug discovery, the objective of this study was to synthesize and evaluate the protein target profiles of electrophilic and photoreactive fully functionalized small-molecule probes (FFSMPs) featuring increased scaffold-, appendage-, and protein-reactive functional group (PRFG) diversity. FFSMPs contain: (1) a protein-binding motif, (2) an electrophilic or photoreactive PRFG for target protein capture, and (3) a terminal alkyne for click chemistry-based proteomic applications.

Design: Survey, cross-sectional.
Setting: Nine spinal cord injury (SCI) Model Systems Centers.
Background: Robotic exoskeletons have changed rehabilitation care available to people after spinal cord injury (SCI). Yet, the current evidence base is insufficient to identify the optimal dose and neurophysiological mechanism of robotic exoskeleton gait training (RGT) as an effective rehabilitation approach. This study will (1) examine whether the frequency of RGT after motor incomplete SCI impacts function and health outcomes, (2) analyze the neuroplastic effects of RGT dose, and (3) evaluate the safety, tolerability, and feasibility of delivering RGT.

People in the subacute phase after stroke who are unable to walk are most likely to benefit the greatest from use of overground robotic gait training (RGT). This study will provide preliminary evidence regarding the clinical use and efficacy of RGT during the subacute phase of stroke recovery as well as observational findings associated with the safety, tolerability, feasibility, and cost of delivering RGT during inpatient stroke rehabilitation.

The experimental design consists of a compact cryostat coupled with a sensitive electro-optical Kerr device to monitor the stability of the electric fields. The behavior of nitrogen and helium ions on a poly(methyl methacrylate) (PMMA) surface was compared to a PMMA surface coated with a mixture of deuterated polystyrene and deuterated polybutadiene.

Overground exoskeleton gait training (OEGT) has been shown to be feasible in both settings, yet its use as an intervention across the continuum has not yet been reported.
Objectives: This study describes OEGT for patients with SCI across the continuum and its effects on clinical outcomes.
Objective: To describe the safety, feasibility, and tolerability of overground exoskeleton gait training (OEGT) integrated into clinical practice for patients after severe acquired brain injury (ABI).
Setting: Inpatient rehabilitation hospital.
Participants: Eligible patients with severe ABI met the following criteria: age > 18, medically stable, met exoskeleton frame limitations, and a score of ≤ 3 on the motor function portion of the Coma Recovery Scale - Revised (CRS-R).
Background: Kinematic driving data studies are a novel methodology relevant to health care, but prior studies have considerable variance in their methods, populations, and findings suggesting a need for critical analysis and appraisal for feasibility and methodological guidelines.
Methods: We assessed kinematic driving studies of adults with chronic conditions for study feasibility, characteristics, and key findings, to generate recommendations for future study designs, and to identify promising directions for applications of kinematic driving data. PRISMA was used to guide the review and searches included PubMed, CINAHL, and Compendex.
Background And Aims: Participation in a healthy lifestyle intervention such as the Diabetes Prevention Program Group Lifestyle Balance-adapted for stroke (GLB-CVA) may reduce stroke burden. Identifying biomarkers associated with lifestyle changes may enhance an individualized approach to stroke recovery. We investigated metabolic biomarkers related to cardiovascular and neurological function in individuals with stroke in the GLB-CVA study and healthy (non-stroke) individuals.

Materials And Methods: The respondents were enrolled from different organizations or support groups who were conducting activities specifically for stroke victims and/or their caregivers.
Background: Experience of stroke is associated with an increased risk for diabetes and metabolic syndrome, yet few interventions exist that have been tailored to the population's unique needs.
Purpose: To examine adherence and efficacy of the Diabetes Prevention Program Group Lifestyle Balance program (DPP-GLB) modified for individuals post stroke (GLB-CVA) using a randomized controlled trial.
Methods: Adults (18-85 years of age), >12 months post stroke, and body mass index ≥25 kg/m2 were included in this study.
Background: Overground exoskeleton gait training (OEGT) after neurological injury is safe, feasible, and may yield positive outcomes. However, no recommendations exist for initiation, progression, or termination of OEGT. This retrospective study highlights the clinical use and decision-making of OEGT within the physical therapy plan of care for patients after neurological injury during inpatient rehabilitation.

Evidence-based interventions for this population are needed and our work modifying and examining the efficacy of the Diabetes Prevention Program Group Lifestyle Balance (GLB-TBI) are promising. Our recent randomized controlled trial included 57 adults with TBI who completed the GLB-TBI in-person and lost 17.

Sleep apnea is another comorbidity that may exacerbate, and/or be exacerbated by, vestibular dysfunction.
Objective: To examine the relationship between sleep apnea and vestibular symptoms in V/SM diagnosed with TBI of any severity.
Introduction: Participation in moderate-to-vigorous intensity physical activity (MVPA) is recommended to reduce chronic disease risk in individuals with tetraplegia. Assessing exercise intensity using traditional methods, such as heart rate, may be inaccurate in patients with motor-complete tetraplegia due to autonomic and neuromuscular dysfunction. Direct gas analysis may be more accurate.

Participants were categorized into four groups: low motor/low cognition, low motor/high cognition, high motor/low cognition, or high motor/high cognition.
Background: Lower body positive pressure (LBPP) may provide a novel intervention for gait training in neurological conditions. Nonetheless, studies investigating the safety and feasibility of LBPP in patients with stroke are insufficient.
Objectives: The purpose of this study was to evaluate the safety and feasibility of LBPP as a rehabilitation intervention for individuals with chronic stroke.
Background: Scant research has focused on posttraumatic stress disorder (PTSD) in the SCI population, despite high prevalence estimates. Fortunately, prolonged exposure therapy (PE) is a well-researched and highly effective treatment for PTSD. Our recent clinical trial showed that standard 12-session PE was effective for PTSD treatment among inpatients with SCI.

Although there is a growing amount of evidence supporting camps for individuals with chronic illness, there is no known research on camp experiences for those who require ventilatory support. The purpose of this study was to examine the perceptions of attending camp on self-esteem, social functioning, emotional functioning, and physical functioning for individuals who require ventilatory support.

The purposes of this study are to prospectively examine the efficacy of a stakeholder informed RGT program compared to usual care gait training (UC) during inpatient rehabilitation in people with incomplete SCI and compare the intensity of RGT and UC gait training during inpatient rehabilitation.
Study Design: 128 patients with incomplete SCI admitted to our inpatient rehabilitation facility will be screened for eligibility and randomized to either the RGT or UC group.
We report an improved measurement of the free neutron lifetime τ_{n} using the UCNτ apparatus at the Los Alamos Neutron Science Center. We count a total of approximately 38×10^{6} surviving ultracold neutrons (UCNs) after storing in UCNτ's magnetogravitational trap over two data acquisition campaigns in 2017 and 2018. We extract τ_{n} from three blinded, independent analyses by both pairing long and short storage time runs to find a set of replicate τ_{n} measurements and by performing a global likelihood fit to all data while self-consistently incorporating the β-decay lifetime.
