Review
Spinal cord injury (SCI) is a complex neurological condition caused by trauma, inflammation, and other diseases, which often leads to permanent changes in strength and sensory function below the injured site. Changes in the microenvironment and secondary injuries continue to pose challenges for nerve repair and recovery after SCI. Recently, there has been progress in the treatment of SCI with the use of scaffolds for neural tissue engineering. Polymeric fibers fabricated by electrospinning have been increasingly used in SCI therapy owing to their biocompatibility, complex porous structure, high porosity, and large specific surface area. Polymer fibers simulate natural extracellular matrix of the nerve fiber and guide axon growth. Moreover, multiple channels of polymer fiber simulate the bundle of nerves. Polymer fibers with porous structure can be used as carriers loaded with drugs, nerve growth factors and cells. As conductive fibers, polymer fibers have electrical stimulation of nerve function. This paper reviews the fabrication, characterization, and application in SCI therapy of polymeric fibers, as well as potential challenges and future perspectives regarding their application.

Review
PURPOSE OF REVIEW
Adaptive sports (AdS), sports modified or created to accommodate persons with disabilities, have been gaining popularity over the last decade. The benefits of exercise in the able-bodied population are well-established. Literature in adaptive sport and the para-athlete continues to improve but is not yet as comprehensive as their able-bodied peers, in part due to the heterogeneity of participants. In this review, we appraise the recent literature pertaining to AdS and identify developing areas within the field.
RECENT FINDINGS
AdS have been shown to have positive health benefits as well as positive psychosocial benefits. Para-athletes often must overcome a variety of barriers to participation, such as transportation, accessibility, and socioeconomic factors. Facilitators to participation have also been identified, including pre-injury interest in sports, male sex, younger age, and more. In addition to well-known sports like handcycling and wheelchair basketball, adaptive sport continues to evolve, in part due to the COVID-19 pandemic, now including virtual options and E-sports. Para-athletes are also being more closely monitored and evaluated pre, peri, and post competition for injury and injury prevention, including in the realm of concussion management, requiring healthcare professionals, coaches, players, and all to gain further knowledge in adaptive sport and the participating para-athletes.
SUMMARY
The physical, psychological, and social benefits of adaptive sports for individuals with disabilities are numerous. Addressing barriers to participation, including novel forms of AdS that utilize innovative technology, may allow more individuals to benefit from AdS.

Frontiers in Integrative Neuroscience 2022To evaluate the evidence for altered cortical and spinal cord functions in individuals with patellofemoral pain (PFP).
OBJECTIVE
To evaluate the evidence for altered cortical and spinal cord functions in individuals with patellofemoral pain (PFP).
METHODS
We conducted a comprehensive search of databases to appraise and analyze the studies published prior to December 10, 2021 that examined spinal reflex excitability measured using Hoffmann reflex (H-reflex) amplitudes, corticospinal excitability measured using transcranial magnetic stimulation (TMS)-elicited motor evoked potential (MEP) amplitudes, motor threshold (MT), or stimulus-response (SR) curves, cortical reorganization assessed using TMS cortical mapping or structural magnetic resonance imaging (MRI), or functional changes of the brain assessed using functional MRI (fMRI) in individuals with PFP.
RESULTS
Eight studies were eligible for analyses. While an earlier study showed that pain had no effect on the H-reflex amplitude of the quadriceps muscle, more recent evidence reported a decrease in vastus medialis (VM) H-reflex amplitude in participants with PFP. VM H-reflex amplitude was correlated with pain, chronicity, physical function, and isometric knee extensor torque production in participants with PFP. Altered corticospinal excitability was reported in participants with PFP, observed as increased MT in the VM and vastus lateralis (VL) muscles. In addition, cortical reorganization has been observed, where decreased number of cortical peaks, shifts and reduced volumes, and increased overlap of motor cortex representations for the VM, VL, and rectus femoris (RF) muscles were reported in participants with PFP.
CONCLUSION
There is emerging evidence on altered cortical and spinal cord functions in individuals with PFP, however, solid conclusions cannot be drawn due to limited literature available. Further research is needed to better understand the adaptations of the brain and spinal cord in this population.

Review
Human immunodeficiency virus type 1 (HIV-1) causes various diseases in different age groups. Neurological manifestations of HIV are common and add to morbidity and mortality. It was previously thought that the central nervous system (CNS) was involved only in the advanced stages of the disease. However, recent evidence supports pathological involvement of the CNS from initial viral entry. Some of the CNS manifestations in children share similarities to neurologic disorders of HIV-infected adult patients, while others are unique to the pediatric population. Many HIV-related neurologic complications seen in adults are rarely encountered in children with AIDS and vice versa. However, with recent advances in the treatment, more HIV-infected children are surviving into adulthood. A systematic review of the available literature was performed to study the manifestations, causes, outcomes, and treatment of primary neurologic disorders in children with HIV. Online databases (Ovid Medline, Embase and PubMed), websites from the World Health Organization, commercial search engines, including Google, and chapters on HIV in standard textbooks of pediatrics and medicine were reviewed. HIV-associated neurological syndromes can be classified into four types: primary HIV neurological diseases, treatment-related neurological diseases, adverse neurological effects of antiretroviral therapy and secondary/opportunistic neurological illness. These conditions are not mutually exclusive and may co-exist in a given patient. This narrative review will focus mainly on the primary neurological manifestations of HIV in children.

Review
Intramedullary spinal cord abscess (ISCA) is a rare clinical pathology of the central nervous system that usually accompanies other underlying comorbidities. Traditionally it has been associated with significant mortality and neurological morbidities because it is often difficult to diagnose promptly, owing to its nonspecific clinical and neuroimaging features. The mortality rate and the outcome of these infections have been improved by the introduction into clinical practice of antibiotics, advanced neuroimaging modalities, and immediate surgery. We report the case of a 65-year-old male patient who presented with a progressive spastic gait and lumbar pain, predominantly in the left leg. An MRI image revealed an expansile intramedullary cystic mass in the thoracic spinal cord, which was initially diagnosed as a spinal tumor. He underwent laminectomy and myelotomy, and eventually the pus was drained from the abscess. The follow-up MRI showed improvement, but the patient's paraplegia persisted. In light of his persistent hypoesthesia and paraplegic gait with developing neuropathic pain, he was readmitted, and an MRI of his lumbar spine revealed multilevel degenerative disease and tethered spinal cord syndrome with compression of the medulla at the L2-L3 level. The patient underwent central flavectomy with bilateral foraminotomy at the L2-L3 level, and the medulla was decompressed. Postoperatively, his neurological symptoms were significantly improved, and he was discharged from hospital on the third day after admission. In support of our case, we systematically reviewed the recent literature and analyzed cases published between 1949 and May 2022, including clinical features, mechanisms of infection, predisposing factors, radiological investigations, microbial etiologies, therapies and their duration, follow-ups, and outcomes. Initial clinical presentation can be misleading, and the diagnosis can be challenging, because this condition is rare and coexists with other spinal diseases. Hence, a high index of suspicion for making an accurate diagnosis and timely intervention is required to preclude mortality and unfavorable outcomes. Our case is a clear example thereof. Long-term follow-up is also essential to monitor for abscess recurrences.

Review
BACKGROUND
Traumatic spinal cord injury (TSCI) is a highly fatal and disabling event, and its incidence rate is increasing in China. Therefore, we collated the epidemiological factors of TSCI in different regions of China to update the earlier systematic review published in 2018.
METHOD
We searched four English and three Chinese electronic databases from 1978 to October 1, 2022. From the included reports, information on sample characteristics, incidence, injury characteristics, prognostic factors, and economic burden was extracted. The selection of data was based on the PRISMA statement. The quality of the included studies was assessed by the Agency for Healthcare Research and Quality (AHRQ) tool. The results of the meta-analysis were presented in the form of pooled frequency and forest plots.
RESULTS
A total of 59 reports (60 studies) from 23 provinces were included, of which 41 were in the Chinese language. The random pooled incidence of TSCI in China was estimated to be 65.15 per million (95% CI: 47.20-83.10 per million), with a range of 6.7 to 569.7 per million. The pooled male-to-female ratio was 1.95:1. The pooled mean age of the cases at the time of injury was 45.4 years. Motor vehicle accidents (MVAs) and high falls were found to be the leading causes of TSCI. Incomplete quadriplegia and AISA/Frankel grade D were the most common types of TSCI. Cervical level injury was the most prevalent. The pooled in-hospital mortality and complication rates for TSCI in China were 3% (95% CI: 2-4%) and 35% (95% CI: 23-47%). Respiratory problems were the most common complication and the leading cause of death.
CONCLUSION
Compared with previous studies, the epidemiological data on TSCI in China has changed significantly. A need to update the data over time is essential to implement appropriate preventive measures and formulate interventions according to the characteristics of the Chinese population.

Review
The level of injury is linked with biochemical alterations and limitations in physical activity among individuals with spinal cord injury (SCI), which are crucial determinants of body composition. We searched five electronic databases from inception until 22 July 2021. The pooled effect estimates were computed using random-effects models, and heterogeneity was calculated using I statistics and the chi-squared test. Study quality was assessed using the Newcastle-Ottawa Scale. We pooled 40 studies comprising 4872 individuals with SCI (3991 males, 825 females, and 56 sex-unknown) in addition to chronic SCI (median injury duration 12.3 y, IQR 8.03-14.8). Individuals with tetraplegia had a higher fat percentage (weighted mean difference (WMD) 1.9%, 95% CI 0.6, 3.1) and lower lean mass (WMD -3.0 kg, 95% CI -5.9, -0.2) compared to those with paraplegia. Those with tetraplegia also had higher indicators of central adiposity (WMD, visceral adipose tissue area 0.24 dm 95% CI 0.05, 0.43 and volume 1.05 L 95% CI 0.14, 1.95), whereas body mass index was lower in individuals with tetraplegia than paraplegia (WMD -0.9 kg/mg, 95% CI -1.4, -0.5). Sex, age, and injury characteristics were observed to be sources of heterogeneity. Thus, individuals with tetraplegia have higher fat composition compared to paraplegia. Anthropometric measures, such as body mass index, may be inaccurate in describing adiposity in SCI individuals.

Meta-Analysis Review
BACKGROUND CONTEXT
Posterior cervical fusion (PCF) with decompression is a treatment option for patients with conditions such as spondylosis, spinal stenosis, and degenerative disc disorders that result in myelopathy or radiculopathy. The annual rate, number, and cost of PCF in the United States has increased. Far fewer studies have been published on PCF outcomes than on anterior cervical fusion (ACF) outcomes, most likely because far fewer PCFs than ACFs are performed.
PURPOSE
To evaluate the patient-reported and clinical outcomes of adult patients who underwent subaxial posterior cervical fusion with decompression.
STUDY DESIGN/SETTING
Systematic review and meta-analysis.
PATIENT SAMPLE
The total number of patients in the 31 articles reviewed and included in the meta-analysis was 1,238 (range 7-166).
OUTCOME MEASURES
Preoperative to postoperative change in patient-reported outcomes (visual analog scales for arm pain and neck pain, Neck Disability Index, Japanese Orthopaedic Association [JOA] score, modified JOA score, and Nurick pain scale) and rates of fusion, revision, and complications or adverse events.
METHODS
This study was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and a preapproved protocol. PubMed and Embase databases were searched for articles published from January 2001 through July 2018. Statistical analyses for patient-reported outcomes were performed on the outcomes' raw mean differences, calculated as postoperative value minus preoperative value from each study. Pooled rates of successful fusion, revision surgery, and complications or adverse events, and their 95% confidence intervals, were also calculated. Two subgroup analyses were performed: one for studies in which only myelopathy or radiculopathy (or both) were stated as surgical indications and the other for studies in which only myelopathy or ossification of the posterior longitudinal ligament (or both) were stated as surgical indications. This study was funded by Providence Medical Technology, Inc. ($32,000).
RESULTS
Thirty-three articles were included in the systematic review, and 31 articles were included in the meta-analysis. For all surgical indications and for the 2 subgroup analyses, every cumulative change in patient-reported outcome improved. Many of the reported changes in patient-reported outcome also exceeded the minimal clinically important differences. Pooled outcome rates with all surgical indications were 98.25% for successful fusion, 1.09% for revision, and 9.02% for complications or adverse events. Commonly reported complications or adverse events were axial pain, C5 palsy, transient neurological worsening, and wound infection.
CONCLUSIONS
Posterior cervical fusion with decompression resulted in significant clinical improvement, as indicated by the changes in patient-reported outcomes. Additionally, high fusion rates and low rates of revision and of complications and adverse events were found.

Meta-Analysis Review
OBJECTIVE
The rate of endovascular repair of thoracoabdominal aortic aneurysms (TAAA-ER) has increased considerably in recent years. Although the mortality and morbidity rates have improved, the incidence of spinal cord ischemia (SCI) has not declined significantly. The aim of the present systematic review and meta-analysis was to examine the SCI rates with respect to the efficacy of the different approaches.
METHODS
Cohort studies and case series (>20 patients) reporting SCI rates after TAAA-ER were eligible for inclusion. The primary outcome measure was the evaluation of SCI. The moderators considered were primarily the staged vs nonstaged approach, the use of cerebrospinal fluid drainage (CSFD), and TAAA extension. The permanent SCI and mortality rates were extracted.
RESULTS
A total of 27 studies with 2333 patients were included in the meta-analysis. The pooled estimate for SCI was 11% (95% confidence interval [CI], 8%-15%; I, 79%). For extent I, II, III, and V TAAA, the pooled SCI rate was 13% (95% CI, 10%-17%; I, 69%). For extent IV TAAA, the pooled SCI rate was 6% (95% CI, 3%-10%; I, 62%). A staged TAAA-ER approach was used in 20 studies and a nonstaged approach in 8 (1 study had included both). A lower pooled SCI rate was identified after staged than after nonstaged TAAA-ER (9% vs 18%, respectively; P = .02). Staging was accomplished in >1 month in nine studies and ≤1 month in two studies, leading to similar SCI rates (7% vs 11%, respectively; P = .26). The method of staging (thoracic endoprosthesis or temporary aortic sac perfusion) did not affect the SCI rates. Symptomatic CSFD was associated with a similar pooled rate of SCI compared with prophylactic CSFD (10% vs 10%, respectively; P = .99). The pooled permanent SCI rate was 6% (6% for extent I, II, III, and V TAAA; and 3% for extent IV TAAA). The pooled rate of 30-day mortality was 7%, with a similar incidence for the staged and nonstaged approaches (6% vs 9%, respectively). Interstage mortality was reported in 9 studies, with a pooled estimate rate of 1.6%.
CONCLUSIONS
SCI had occurred in 11% of TAAA-ER, and one half of these cases were permanent. A staged approach can reduce SCI rates independently of the timing and method adopted. The overall mortality rate for staged TAAA-ER was 7%, with one fifth of the deaths (1.6%) occurring between stages.

Review
BACKGROUND
Self-management plays a critical role in maintaining and improving the health of persons with spinal cord injury (SCI). Despite their potential, existing mobile health (mHealth) self-management support (SMS) tools for SCI have not been comprehensively described in terms of their characteristics and approaches. It is important to have an overview of these tools to know how best to select, further develop, and improve them.
OBJECTIVE
The objective of this systematic literature review was to identify mHealth SMS tools for SCI and summarize their characteristics and approaches to offering SMS.
METHODS
A systematic review of the literature published between January 2010 and March 2022 was conducted across 8 bibliographic databases. The data synthesis was guided by the self-management task taxonomy by Corbin and Strauss, the self-management skill taxonomy by Lorig and Holman, and the Practical Reviews in Self-Management Support taxonomy. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) standards guided the reporting.
RESULTS
A total of 24 publications reporting on 19 mHealth SMS tools for SCI were included. These tools were introduced from 2015 onward and used various mHealth technologies and multimedia formats to provide SMS using 9 methods identified by the Practical Reviews in Self-Management Support taxonomy (eg, social support and lifestyle advice and support). The identified tools focused on common SCI self-management areas (eg, bowel, bladder, and pain management) and overlooked areas such as sexual dysfunction problems and environmental problems, including barriers in the built environment. Most tools (12/19, 63%) unexpectedly supported a single self-management task instead of all 3 tasks (ie, medical, role, and emotional management), and emotional management tasks had very little support. All self-management skills (eg, problem-solving, decision-making, and action planning) had coverage, but a single tool addressed resource use. The identified mHealth SMS tools were similar in terms of number, introduction period, geographical distribution, and technical sophistication compared with SMS tools for other chronic conditions.
CONCLUSIONS
This systematic literature review provides one of the first descriptions of mHealth SMS tools for SCI in terms of their characteristics and approaches to offering SMS. This study's findings highlight a need for increased coverage of key SMS for SCI components; adopting comparable usability, user experience, and accessibility evaluation methods; and related research to provide more detailed reporting. Future research should consider other data sources such as app stores and technology-centric bibliographic databases to complement this compilation by identifying other possibly overlooked mHealth SMS tools. A consideration of this study's findings is expected to support the selection, development, and improvement of mHealth SMS tools for SCI.
