Impact of COVID-19 on socio-behavioural, health and oral health-related aspects on spinal cord injury patients: a cross-sectional study

Background: Spinal cord injury (SCI) is a damaging, life-altering injury, which is estimated to have an annual global incidence of 40 to 80 cases per million population and is two to five times more possible to die prematurely. This study aims to evaluate the impact of COVID-19 on socio-behavioural, health, and oral health-related aspects of spinal cord injury patients. Methods: This cross-sectional study was conducted among 50 spinal cord injury patients in the rehabilitation center in Chennai, Tamil Nadu, which was conducted between May and June 2022. Results: The comparison of mean distribution scores based on DMFT showed that complete injury patients had a lower DMFT score of 6.40 when compared to incomplete injury (8.41). The periodontal status assessment revealed that SCI with complete injury had a lower mean number of teeth with gingival bleeding and periodontal pocket (3.81 and 2.31 respectively) when compared to incomplete injury (7.12 and 4.49). Moreover, the impact of COVID-19 on the socio-behavior and health status was found to be higher in complete injury than that in incomplete injury patients. Conclusions: Therefore, this pandemic highlights the need to advocate the development of a nationwide SCI registry or surveillance system is fundamental to an understanding of the epidemiology and, hence, the prevention of this emerging health burden.

Chaotic Model of Muscle and Joint Interactions Based on CPG for Rehabilitation of Incomplete Spinal Cord Injury Patients

The aim of modeling musculoskeletal systems is to understand the mechanisms of locomotion control in terms of neurophysiology and neuroanatomy. The complexity and unique nature of neuromuscular systems, however, make control problems in these systems very challenging due to several characteristics including speed and precision. Thus, their investigation requires the use of simple and analyzable methods. Consequently, taking into account the central pattern generator’s (CPG) function, we attempted to create a structured chaotic model of how human joints and muscles interact for the purpose of facilitating gait and rehabilitation in patients with incomplete spinal cord injury. The four muscle groups used in this model are gluteus, and hip flexor groups for flexion and extension of the hip joints as well as hamstring muscles and vasti muscles for flexion and extension of the knee joint. The results indicate that the output of the chaotic model of muscle and joint interactions in a healthy state would be chaotic, while in the incomplete spinal cord injury state, it would remain a fixed point. For model rehabilitation, afferent nerve stimulation is used in a CPG model; based on the modeling results, by applying coefficients of 1.98, 2.21, and 3.1 to the values of Ia, II, and Ib afferent nerves, the incomplete spinal cord injury model state is changed from a fix-point to periodic in a permanent fashion, suggesting locomotion with rehabilitation in our model. Based on the results obtained from the chaotic model of muscle and joint interactions as well as the comparisons made with reference papers, it can be stated that this model has acceptable output while enjoying simple computations and can predict different norms.

Systematic Review of Cell Therapy Efficacy in Human Chronic Spinal Cord Injury.

Spinal cord injury (SCI) is one of the most debilitating problems for humans. About 6 months after the initial injury, a cascade of secondary cellular and molecular events occurs and the primary damage enters the chronic phase. Current treatments are not curative. One of the new treatment methods is the use of cell therapy, which is gradually being tested in clinical trials to improve the symptoms of SCI patients. In this review article, we investigated the effect of different cell therapy trials in improving patients' symptoms and their paraclinical indicators. In the 72 final reviewed studies with 1144 cases and 186 controls, 20 scores were recorded as outcomes. We categorized the scores into seven groups. In upper extremity motor score, daily living function, trunk stability, postural hypotension, somatosensory evoked potential, and motor evoked potential scores, the bone marrow hematopoietic stem cell therapy had a more healing effect. In the International Association of Neurorestoratology SCI Functional Rating Scale, light touch score, bowel function, decreased spasticity, Visual Analog Scale, and electromyography scores, the bone marrow mesenchymal stem cell had more impact. The olfactory ensheathing cell had a greater effect on lower extremity motor score and pinprick scores than other cells. The embryonic stem cell had the greatest effect in improving the important score of the American Spinal Injury Association scale. Based on the obtained results, it seems that a special cell should be used to improve each symptom of patients with chronic SCI, and if the improvement of several harms is involved, the combination of cells may be effective. Impact statement Compared to similar review articles published so far, we reviewed the largest number of published articles, and so the largest number of cases and controls, and the variety of cells we examined was more than other published articles. We concluded that different cells are effective for improving the symptoms and paraclinical indicators of patients with chronic spinal cord injury. Bone marrow hematopoietic stem cell and bone marrow mesenchymal stem cell have had the higher overall mean effect in more scores (each in six scores). If the improvement of several harms is involved, the combination of cells may be effective.

Association between oral health-related quality of life and oral health status in people with spinal cord injuries during the COVID pandemic: a crosssectional study

Aim: Spinal cord injury (SCI) is a serious medical disorder that frequently causes significant morbidity and long-term disability. Untreated oral disease is more common in people with physical limitations. Evidence suggests that dry mouth increases the risk of dental caries by encouraging the growth of dental plaque. Therefore, this study is being considered to determine the association between oral health status and oral health-related quality of life (OHRQoL) among SCI patients during the COVID pandemic. Materials & methods: This cross-sectional study included 50 SCI patients. The sample size was determined using G*Power software (version 3.1).Information on demographic characteristics and socioeconomic status was also obtained using the Modified Kuppuswamy scale, 2021. OHRQoL was assessed using the Oral Health Impact Profile (OHIP-14) questionnaire, and the World Health Organization Proforma, 2013, was used to record oral health status. Descriptive statistics can be used to compute percentages, means, and standard deviations. Wilcoxon-signed ranks testing was done to compare the association between mean OHIP and oral health status. Results: 11 of them had complete spinal injuries, while the other 39 had incomplete spinal injuries. Patients with incomplete injuries had more decaying, missing, and filled teeth, gingival bleeding, periodontal pockets, and OHIP scores than patients with complete injuries. The mean OHIP was 20.73. The study participants' mean OHIP and oral health status showed a significant association (P=0.000). Conclusion: SCI patients appear to have poor oral health. The association between oral health status and OHRQoL was statistically significant. It is crucial to support and facilitate patient’s and caregiver’s education on oral health-related issues.

Screening biomarkers for spinal cord injury using weighted gene co-expression network analysis and machine learning.

JOURNAL/nrgr/04.03/01300535-202412000-00028/figure1/v/2024-04-08T165401Z/r/image-tiff Immune changes and inflammatory responses have been identified as central events in the pathological process of spinal cord injury. They can greatly affect nerve regeneration and functional recovery. However, there is still limited understanding of the peripheral immune inflammatory response in spinal cord injury. In this study, we obtained microRNA expression profiles from the peripheral blood of patients with spinal cord injury using high-throughput sequencing. We also obtained the mRNA expression profile of spinal cord injury patients from the Gene Expression Omnibus (GEO) database (GSE151371). We identified 54 differentially expressed microRNAs and 1656 differentially expressed genes using bioinformatics approaches. Functional enrichment analysis revealed that various common immune and inflammation-related signaling pathways, such as neutrophil extracellular trap formation pathway, T cell receptor signaling pathway, and nuclear factor-κB signal pathway, were abnormally activated or inhibited in spinal cord injury patient samples. We applied an integrated strategy that combines weighted gene co-expression network analysis, LASSO logistic regression, and SVM-RFE algorithm and identified three biomarkers associated with spinal cord injury: ANO10, BST1, and ZFP36L2. We verified the expression levels and diagnostic performance of these three genes in the original training dataset and clinical samples through the receiver operating characteristic curve. Quantitative polymerase chain reaction results showed that ANO10 and BST1 mRNA levels were increased and ZFP36L2 mRNA was decreased in the peripheral blood of spinal cord injury patients. We also constructed a small RNA-mRNA interaction network using Cytoscape. Additionally, we evaluated the proportion of 22 types of immune cells in the peripheral blood of spinal cord injury patients using the CIBERSORT tool. The proportions of naïve B cells, plasma cells, monocytes, and neutrophils were increased while the proportions of memory B cells, CD8+ T cells, resting natural killer cells, resting dendritic cells, and eosinophils were markedly decreased in spinal cord injury patients increased compared with healthy subjects, and ANO10, BST1 and ZFP26L2 were closely related to the proportion of certain immune cell types. The findings from this study provide new directions for the development of treatment strategies related to immune inflammation in spinal cord injury and suggest that ANO10, BST1, and ZFP36L2 are potential biomarkers for spinal cord injury. The study was registered in the Chinese Clinical Trial Registry (registration No. ChiCTR2200066985, December 12, 2022).

Adiponectin in spinal cord injury: What is the role of nutrition in serum adiponectin concentration?

Objectives: The study aimed to analyze the relationship between serum adiponectin concentration, Mediterranean diet (MD) adherence, and Dietary Approaches to Stop Hypertension (DASH) diet adherence in patients with spinal cord injury (SCI). Patients and methods: Thirty-three SCI patients (21 males, 12 females; median age: 33 years; range, 18 to 65 years) and 33 age-, sex-, and body mass index-matched healthy controls (21 males, 12 females; median age: 33 years; range, 18 to 64 years) were included in this cross-sectional study between March 2021 and March 2022. Serum adiponectin concentrations of all participants were measured. Body weight, height, and neck, hip, waist, and mid-upper arm circumferences were measured. Twenty-four-hour dietary records were obtained by the researchers for evaluation of the nutritional status. The DASH diet score and MD score were measured for each participant. Results: Most of the cases of SCI were due to motor vehicle collisions (n=12, 36.4%) and complete paraplegic. Mid-upper arm circumference, waist circumference, hip circumference, and neck circumference of the patient group were significantly higher than the control group (p=0.020, p=0.002, p=0.042, and p<0.001, respectively). Mediterranean diet scores and DASH diet scores of the patient group were significantly higher than the control group (p<0.001 and p=0.031, respectively). Serum adiponectin concentration of patients was significantly higher than the control group (p=0.049). No correlation was detected between adiponectin concentration, MD score, and DASH diet score in both groups. Conclusion: Although correlation analysis in the current research did not show significant relation between nutrition and adiponectin concentrations, nutrition of patients with SCI, as demonstrated by higher adherence to MD and DASH, may have provided positive effects on adiponectin concentrations. Future studies focused on the effect of a healthy diet intervention on serum adiponectin concentration is warranted.

Role of NLRP3 Inflammasome in Post-Spinal-Cord-Injury Anxiety and Depression: Molecular Mechanisms and Therapeutic Implications.

The majority of research on the long-term effects of spinal cord injury (SCI) has primarily focused on neuropathic pain (NP), psychological issues, and sensorimotor impairments. Among SCI patients, mood disorders, such as anxiety and depression, have been extensively studied. It has been found that chronic stress and NP have negative consequences and reduce the quality of life for individuals living with SCI. Our review examined both human and experimental evidence to explore the connection between mood changes following SCI and inflammatory pathways, with a specific focus on NLRP3 inflammasome signaling. We observed increased proinflammatory factors in the blood, as well as in the brain and spinal cord tissues of SCI models. The NLRP3 inflammasome plays a crucial role in various diseases by controlling the release of proinflammatory molecules like interleukin 1β (IL-1β) and IL-18. Dysregulation of the NLRP3 inflammasome in key brain regions associated with pain processing, such as the prefrontal cortex and hippocampus, contributes to the development of mood disorders following SCI. In this review, we summarized recent research on the expression and regulation of components related to NLRP3 inflammasome signaling in mood disorders following SCI. Finally, we discussed potential therapeutic approaches that target the NLRP3 inflammasome and regulate proinflammatory cytokines as a way to treat mood disorders following SCI.

Patients with Chronic Spinal Cord Injury Display a Progressive Alteration over the Years of the Activation Stages of the T Lymphocyte Compartment.

Spinal cord injury (SCI) is a serious medical condition associated with severe morbidities and disability. Chronic SCI patients present an enhanced susceptibility to infections and comorbidities with inflammatory pathogenesis. Chronic SCI appears to be associated with a systemic dysfunction of the immune system. We investigated the alteration of the pivotal CD4+ and CD8+ T lymphocytes in patients with chronic SCI at different years of evolution. A clinically homogenous population of 105 patients with chronic SCI (31 with time of evolution less than 5 years (SCI SP); 32 early chronic (SCI ECP) with time of evolution between 5 and 15 years; and 42 late chronic (SCI LCP) with time of evolution more than 15 years) and 38 healthy controls were enrolled. SCI ECP and SCI LCP patients showed significant CD4+ and CD8+ T lymphopenia, ascribed to a reduction in naïve and CM subsets. Furthermore, SCI ECP and SCI LCP patients showed a significant reduction in the expression of CD28 on CD8+ T lymphocytes. The expression of CCR6 by CD4+ T lymphocytes was decreased during the evolution of chronic SCI, but on CD8+ T lymphocytes, it was observed during the first 15 years of evolution. In conclusion, the chronic SCI course with severe damage to T lymphocytes mainly worsens over the years of disease evolution.

Spinal cord injury-induced gut dysbiosis influences neurological recovery partly through short-chain fatty acids

Spinal cord injury (SCI) can reshape gut microbial composition, significantly affecting clinical outcomes in SCI patients. However, mechanisms regarding gut–brain interactions and their clinical implications have not been elucidated. We hypothesized that short-chain fatty acids (SCFAs), intestinal microbial bioactive metabolites, may significantly affect the gut–brain axis and enhance functional recovery in a mouse model of SCI. We enrolled 59 SCI patients and 27 healthy control subjects and collected samples. Thereafter, gut microbiota and SCFAs were analyzed using 16 S rDNA sequencing and gas chromatography–mass spectrometry, respectively. We observed an increase in Actinobacteriota abundance and a decrease in Firmicutes abundance. Particularly, the SCFA-producing genera, such as Faecalibacterium, Megamonas, and Agathobacter were significantly downregulated among SCI patients compared to healthy controls. Moreover, SCI induced downregulation of acetic acid (AA), propionic acid (PA), and butyric acid (BA) in the SCI group. Fecal SCFA contents were altered in SCI patients with different injury course and injury segments. Main SCFAs (AA, BA, and PA) were administered in combination to treat SCI mice. SCFA supplementation significantly improved locomotor recovery in SCI mice, enhanced neuronal survival, promoted axonal formation, reduced astrogliosis, and suppressed microglial activation. Furthermore, SCFA supplementation downregulated NF-κB signaling while upregulating neurotrophin-3 expression following SCI. Microbial sequencing and metabolomics analysis showed that SCI patients exhibited a lower level of certain SCFAs and related bacterial strains than healthy controls. SCFA supplementation can reduce inflammation and enhance nourishing elements, facilitating the restoration of neurological tissues and the improvement of functional recuperation. Trial registration: This study was registered in the China Clinical Trial Registry (www.chictr.org.cn) on February 13, 2017 (ChiCTR-RPC-17010621).

Unrecognised autonomic dysreflexia in neurogenic lower urinary tract dysfunction with spinal cord injury as a reason for admission to a cardiac surgical unit

BACKGROUND: In Russia, spinal cord injury occurs in 0.7–6.8% of total injuries. Due to emergence of new rehabilitation protocols, it is extremely important to know the time of occurrence of consequences of spinal cord injury and adequate diagnosis of complications, which allows timely identification of life-threatening conditions of one of the body systems.&#x0D; Clinical case description. We present a clinical case of autonomic dysreflexia in neurogenic lower urinary tract dysfunction after traumatic cervical spinal cord injury in a 17-year-old girl. In traumatic spinal cord injury above the level of the sixth thoracic vertebra, autonomic dysreflexia as a variant of autonomic dysfunction is a common complication. This clinical case will be of interest to clinicians of all specialties who encounter patients with spinal cord injury. It is shown that misinterpreted symptoms of increased blood pressure during bladder filling were the cause of observation and treatment by a cardiologist for arterial hypertension, as well as hospitalization in the cardiac surgery department for planned surgical treatment of renal artery stenosis, which was thought to be the cause of the episodic increases in blood pressure. Lack of knowledge about the presence of autonomic dysfunction in spinal cord injury patients may have led to unnecessary surgical treatment. During the joint management of the patient with a pediatric cardiac surgeon, signs of autonomic dysreflexia were detected against the background of traumatic spinal cord disease at the level of the cervical spine, hypotensive treatment and planned surgical intervention were canceled.&#x0D; Conclusion. Subsequently, an adequate regimen of periodic bladder catheterization and antimuscarinic drug therapy was prescribed, which successfully reduced the dysreflexia.

Predictors of catheter-free voiding after spinal cord injury

Context Despite a high prevalence of neurogenic bladder (NGB) in patients with spinal cord injury (SCI), clinicians are unable to predict long-term bladder outcomes due to variable phenotypes of bladder dysfunction. This study investigates if early bladder events, infections, and spinal cord injury characteristics during rehabilitation admission affect bladder outcomes one year after SCI. Methods This retrospective study included patients with SCI admitted to a tertiary rehabilitation center between 1 January 2016 and 1 January 2020. Data was collected on early bladder management, comorbidities, infections and injury characteristics; level of injury, American Spinal Injury Association Impairment Scale (AIS) classification, and International Standards for Neurological Classification of Spinal Cord Injury lower extremity motor score (LEMS). Results Seventy-two patients met inclusion criteria; 63% (45/72) patients had cervical SCI and 31% (22/72) were complete injuries. Twenty-two percent (16/72) did not use an internal catheter to empty the bladder, improving to 41% (29/72) at one year. On multivariate logistic regression accounting for age, sex, Charlson comorbidity index, LEMS, and infections during admission, higher LEMS (OR 1.104, 95%, CI 1.037–1.176, P = 0.002) associated with catheter-free voiding (CFV) at one year while male sex (OR 0.091, 95% CI 0.012–0.713, P = 0.0225), and non-urologic infections (OR 0.088, 95% CI 0.010–0.768, P = 0.0279) were negatively associated. Conclusions Preserved LEMS early after SCI associates with CFV at one year while male sex and early non-urologic infections such as pneumonia are associated with persistent urinary retention. This can be used to counsel SCI patients on expected bladder recovery and outcomes.

Enhanced axon outgrowth of spinal motor neurons in co-culturing with dorsal root ganglions antagonizes the growth inhibitory environment

IntroductionForming a bridge made of functional axons to span the lesion is essential to reconstruct the motor circuitry following spinal cord injury (SCI). Dorsal root ganglion (DRG) axons are robust in axon growth and have been proved to facilitate the growth of cortical neurons in a process of axon-facilitated axon regeneration. However, whether DRG transplantation affects the axon outgrowth of spinal motor neurons (SMNs) that play crucial roles in motor circuitry remains unclear. MethodsWe investigated the axonal growth patterns of co-cultured DRGs and SMN aggregates (SMNAs) taking advantage of a well-designed 3D-printed in vitro system. Chondroitin sulphate proteoglycans (CSPG) induced inhibitory matrix was introduced to imitate the inhibitory environment following SCI. Axonal lengths of DRG, SMNA or DRG & SMNA cultured on the permissive or CSPG induced inhibitory matrix were measured and compared. ResultsOur results indicated that under the guidance of full axonal connection generated from two opposing populations of DRGs, SMNA axons were growth-enhanced and elongated along the DRG axon bridge to distances that they could not otherwise reach. Quantitatively, the co-culture increased the SMNA axonal length by 32.1 %. Moreover, the CSPG matrix reduced the axonal length of DRGs and SMNAs by 46.2 % and 17.7 %, respectively. This inhibitory effect was antagonized by the co-culture of DRGs and SMNAs. Especially for SMNAs, they extended the axons across the CSPG-coating matrix, reached the lengths close to those of SMNAs cultured on the permissive matrix alone. ConclusionsThis study deepens our understanding of axon-facilitated reconstruction of the motor circuitry. Moreover, the results support SCI treatment utilizing the enhanced outgrowth of axons to restore functional connectivity in SCI patients.

Adherence to continuous positive airway pressure therapy in patients with spinal cord injury andobstructive sleep apnea: trajectories and predictors.

To identify specific determinants of non-adherence or cessation of continuous positive airway pressure (CPAP) therapy in a population of patients with spinal cord injuries (SCI). Retrospective analysis of data from patients with SCI who underwent a full night supervised polysomnography between 2015 and 2021 and presented with moderate to severe obstructive sleep apnea (OSA) and for whom CPAP was indicated. Adherence was studied at 1, 6, and 12 months. Univariate and multivariate analyses were performed to identify factors associated with non-adherence (< 4 h per night or CPAP cessation). Factors studied were demographic and disease-related data and both subjective and objective sleep parameters. A total of 60 patients were included (40% cervical SCI). In univariate analysis, the only predictive parameters of non-adherence observed at 1, 6, and 12 months were the average use of CPAP on the 1st night (p = 0.02) and over the 1st week (p ≤ 0.001). A complete lesion (AIS-A) was predictive of non-adherence at 1 and 6 months (p = 0.02 at 6 months), while mask leakage was associated with non-adherence at 12 months (p = 0.02). Upper limb autonomy and the presence of family caregivers did not appear to be protective. In multivariate analysis, only the average use in the first week remained predictive of adherence (> 4 h) in the short, medium and long term. In patients with SCI and OSA, the 1st week of CPAP treatment seems to be determinant of short-, medium-, and long-term CPAP adherence. Support for SCI patients from the start of treatment is essential and may help avoid treatment failures.

Characterization of Sleep, Emotional, and Cognitive Functions in a New Rat Model of Concomitant Spinal Cord and Traumatic Brain Injuries.

Traumatic injuries to the spinal cord or the brain have serious medical consequences and lead to long-term disability. The epidemiology, medical complications, and prognosis of isolated spinal cord injury (SCI) and traumatic brain injury (TBI) have been well described. However, there are limited data on patients suffering from concurrent SCI and TBI, even if a large proportion of SCI patients have concomitant TBI. The complications associated with this "dual-diagnosis" such as cognitive or behavioral dysfunction are well known in the rehabilitation setting, but evidence-based and standardized approaches for diagnosis and treatment are lacking. Our goal was to develop and characterize a pre-clinical animal model of concurrent SCI and TBI to help identifying "dual-diagnosis" tools. Female rats received a unilateral contusive SCI at the thoracic level alone (SCI group) or combined with a TBI centered on the contralateral sensorimotor cortex (SCI-TBI group). We first validated that the SCI extent was comparable between SCI-TBI and SCI groups, and that hindlimb function was impaired. We characterized various neurological outcomes, including locomotion, sleep architecture, brain activity during sleep, depressive- and anxiety-like behaviors, and working memory. We report that SCI-TBI and SCI groups show similar impairments in global locomotor function. While wake/sleep amount and distribution and anxiety- and depression-like symptoms were not affected in SCI-TBI and SCI groups in comparison to the control group (laminectomy and craniotomy only), working memory was impaired only in SCI-TBI rats. This pre-clinical model of concomitant SCI and TBI, including more severe variations of it, shows a translational value for the identification of biomarkers to refine the "dual-diagnosis" of neurotrauma in humans.

Management of spinal cord injury patients with neurogenic lower urinary tract dysfunction using minimally invasive and surgical therapies in Taiwan.

The main problems of neurogenic lower urinary tract dysfunction (NLUTD) in patients with spinal cord injury (SCI) consist of impaired urine storage, impaired bladder emptying, or both. The priorities in the management of SCI-NLUTD should be preservation of renal function, followed by freedom from urinary tract infections and improvement of quality of life. Management of NLUTD in patients with SCI must be based on urodynamic findings rather than clinical evaluations. In the hospital without urodynamic equipment, careful measurement of intravesical pressure and safety functional bladder capacity in conjunction with clinical assessment are also feasible. Identification of high-risk patients is important for preventing urological complications in patients with chronic SCI. The management of NLUTD should start with conservative bladder management and medical treatment. Patients with SCI should be regularly followed up, and any NLUTDs and urological complications should be adequately treated. When surgical intervention is necessary, less invasive and reversible procedures should be considered first, and any unnecessary surgery should be avoided. This article reports the current evidence and expert opinions on the patient-centered bladder management of NLUTD in chronic SCI patients in Taiwan. To avoid renal function deterioration and urological complications, annual active surveillance of bladder and renal function is mandatory, especially for high-risk SCI patients.

Effect of Driving Simulator Training on Patients' Driving Performance and Self-Efficacy with Paraplegia due to Spinal Cord Injury

Objective: The purpose of this study was to investigate the effect of driving simulator training on the driving performance and self-efficacy of paraplegic patients with spinal cord injury.&#x0D; Method: Driving simulator training was provided to 12 participants with within subjects design, three sessions of basic driving, seven sessions of driving on the driving simulator. After training, performance time and operational performance scores, self-efficacy were analyzed.&#x0D; Results: This study found that the intervention by the driving simulator had statistically significant effects on driving time, performance error, ‘Sudden start’, ‘No neutral gear when stopping’, and ‘Speed violation’ and ‘Social self-efficacy’ of paraplegic spinal cord injury patients (p&lt;.05).&#x0D; Conclusion: Driving simulator training can be a strategy to improve driving performance and social self-efficacy of paraplegic patients with spinal cord injury. Also, patients need sufficient sessions more than 10 times of driving simulator training.

Robot-Aided Motion Analysis in Neurorehabilitation: Benefits and Challenges

In the neurorehabilitation field, robot-aided motion analysis (R-AMA) could be helpful for two main reasons: (1) it allows the registration and monitoring of patients’ motion parameters in a more accurate way than clinical scales (clinical purpose), and (2) the multitude of data produced using R-AMA can be used to build machine learning algorithms, detecting prognostic and predictive factors for better motor outcomes (research purpose). Despite their potential in clinical settings, robotic assessment tools have not gained widespread clinical acceptance. Some barriers remain to their clinical adoption, such as their reliability and validity compared to the existing standardized scales. In this narrative review, we sought to investigate the usefulness of R-AMA systems in patients affected by neurological disorders. We found that the most used R-AMA tools are the Lokomat (an exoskeleton device used for gait and balance rehabilitation) and the Armeo (both Power and Spring, used for the rehabilitation of upper limb impairment). The motion analysis provided by these robotic devices was used to tailor rehabilitation sessions based on the objective quantification of patients’ functional abilities. Spinal cord injury and stroke patients were the most investigated individuals with these common exoskeletons. Research on the use of robotics as an assessment tool should be fostered, taking into account the biomechanical parameters able to predict the accuracy of movements.

Measuring Overweight andObesity inPersons with Spinal Cord Injury: What Do Health Providers Use andWhat are the Challenges?

Obesity is a significant health concern for veterans and individuals with spinal cord injury, yet screening for overweight/obesity can be challenging. This study examines how healthcare providers screen for overweight/obesity and the challenges encountered in identifying overweight/obesity in veterans and persons with spinal cord injury. Healthcare providers who provide care for persons with spinal cord injury completed a semi-structured interview. The interview explored their perspectives on measuring overweight/obesity in persons with spinal cord injury and the challenges they faced. Thematic analysis was used to identify themes that emerged from the interviews. Twenty-five providers (88% female with an average experience of 9.6 ± 7.3 years in providing care for spinal cord injury patients) participated in the interviews. The themes described the health indicators and equipment used to assess overweight/obesity, provider concerns regarding measurement, and criteria for classifying overweight/obesity. Body weight and body mass index were the most commonly used indicators. However, concerns were raised regarding accuracy of these measures for spinal cord injury patients, as well as issues related to the accessibility, calibration, and usability of the equipment. Many providers reported using standard body mass index ranges and categories instead of those specific to spinal cord injury. This study identified the most commonly used indicators of weight or body composition in veterans and persons with spinal cord injury and highlighted providers' concerns with these measures. Future research is needed to identify the most feasible, accurate, and appropriate health indicators that could be used in a clinical setting to identify overweight and obesity in this population.
