A Study of Hypertension and Fitness of Individuals with Spinal Cord Injury: A Cross-Sectional Study

Background/Objectives: Individuals with spinal cord injuries have a higher incidence of chronic conditions such as hypertension and cardiovascular diseases due to a sedentary lifestyle and low levels of physical activity caused by their disability. Additionally, their physical fitness levels are lower compared to those without disabilities. This cross-sectional study aimed to investigate the relationship between hypertension and the fitness of individuals with spinal cord injuries in South Korea while considering differences across sexes and spinal cord injury levels. Methods: This study used data for 835 individuals with spinal cord injuries aged 20–64 years who visited the Korea Paralympic Committee fitness standard test centers from 2018 to 2022, obtained from the Korea Culture Information Sports Association’s big data market. The data were analyzed using a series of t-tests, a one-way analysis of variance, a logistic regression analysis, and the four-quartile method. Results: The prevalence of hypertension was 24.4%, and it was different according to the spinal cord injury impairment level. A lower grip strength, a lower arm curl, and a higher body mass index were associated with increased blood pressure. Conclusions: Therefore, a high level of physical strength in people with spinal cord injuries is thought to contribute to lowering blood pressure.

Risk of Parkinson’s disease in spinal cord injury: a nationwide cohort study in South Korea

Despite the association between spinal cord injury (SCI) and various neurological diseases, the risk of Parkinson’s disease (PD) in SCI is not elucidated yet. Especially, the role of SCI severity and injury level in the risk of PD development is not investigated. Based on the nation-wide cohort data the Korean National Health Insurance Service between 2010 and 2018, we investigated the incidence of PD in 7,182 patients with SCI compared with 24,844 age- and sex-matched controls. Adjusted hazard ratio and 95% confidence interval (CI) were calculated using Cox proportional hazards regression. We compared the risk of PD based on the degree of disability (without disability, mild, severe) and SCI level (cervical, thoracic, and lumbar). During the mean follow-up duration of 4.31 years, patients with SCI had a higher risk of PD compared with matched controls. The PD risk was greater among patients with SCI with disability than in those without disability, especially those with mild disability. Additionally, cervical-level injury was associated with the highest risk in patients with SCI without disability, while thoracic-level injury was associated with the highest risk in those with disability. Our study found patients with SCI have increased risk of PD, particularly those with disability and thoracic-level injuries.

Clinical Risk Factors Associated with the Need for Tracheostomy in Traumatic Cervical and High Thoracic Spinal Cord Injury

BackgroundOur objective was to assess the association of completeness and level of spinal cord injury (SCI) with the need for tracheostomy and identify additional risk factors predictive of tracheostomy. MethodsThis was a retrospective review of patients with SCI between January 2017 and December 2022. ResultsPatients with complete SCI were roughly thirty-three times more likely to have a tracheostomy when compared to incomplete injury (82% vs 12%, p<0.001, OR = 32.9). The rate of tracheostomy did not differ between spinal cord levels for complete (p=0.68) or incomplete (p=0.08) injuries. Penetrating injury, low GCS, high ISS, and polytrauma were associated with tracheostomy need in incomplete SCI. ConclusionComplete injury was statistically significantly associated with the need for tracheostomy while level of injury failed to reach significance. Patients with incomplete SCI that have certain clinical risk factors should be considered for early tracheostomy.

Spinal Cord Injury Enhances Lung Inflammation and Exacerbates Immune Response After Acute Lung Injury.

The severity of spinal cord injury (SCI) is closely tied to pulmonary function, especially in cases of higher SCI levels. Despite this connection, the underlying pathological mechanisms in the lungs post-SCI are not well understood. Previous research has established a connection between disrupted sympathetic regulation and splenocyte apoptosis in high thoracic SCI, leading to pulmonary dysfunction. The aim of this study was to investigate whether mice with low-level SCI exhibit increased susceptibility to acute lung injury by eliciting systemic inflammatory responses that operate independently of the sympathetic nervous system. Here, we employed T9 contusion SCI and exposed mice to aerosolized lipopolysaccharide (LPS) to simulate lung inflammation associated with acute respiratory distress syndrome (ARDS). Twenty-four hours post-LPS exposure, lung tissues and bronchoalveolar lavage (BAL) fluid were analyzed. LPS markedly induced proinflammatory gene expression (SAA3, IRG1, NLRP3, IL-1beta, MCP-1) and cytokine release (IL-1beta, IL-6, MCP-1) in SCI mice compared to controls, indicating an exaggerated inflammatory response. Infiltration of Ly6G/C positive neutrophils and macrophages was significantly higher in SCI mice lungs post-LPS exposure. Interestingly, spleen size and weight did not differ between control and SCI mice, suggesting that T9 SCI alone does not cause spleen atrophy. Notably, bone-marrow-derived macrophages (BMDMs) from SCI mice exhibited hyper-responsiveness to LPS. This study demonstrated an increase in lung inflammation and immune responses subsequent to low-level T9 SCI, underscoring the widespread influence of systemic inflammation post-SCI, especially pronounced in specific organs like the lungs.

A Systematic Review of the Impact of Spinal Cord Injury on Costs and Health-Related Quality of Life.

To systematically review the health-related quality of life (HRQoL) burden and costs of spinal cord injury (SCI) on health services, patients and wider society. A systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement was conducted in March 2021 through Scopus, PubMed and Embase databases. Inclusion criteria were quantitative studies on SCI reporting healthcare costs, social costs and/or HRQoL measured with the Euroqol EQ-5D or Short-Form 36. Risk of bias was assessed using the QualSyst tool. Descriptive analyses, random-effects direct meta-analysis and random-effects meta-regression were conducted. A total of 67 studies were eligible for inclusion. SCI individuals tend to report higher HRQoL in mental than physical dimensions of the Short-Form 36. Neurological level of SCI negatively affects HRQoL. Cross-sectional studies find employment is associated with better HRQoL, but the effect is not observed in longitudinal studies. The estimated lifetime expenditure per individual with SCI ranged from US$0.7 million to US$2.5 million, with greater costs associated with earlier age at injury, neurological level, UnitedStates of America healthcare setting and the inclusion of non-healthcare items in the study. SCI is associated with low HRQoL on mobility and physical dimensions. Mental health scores tend to be greater than physical scores, and most dimensions of HRQoL appear to improve over time, at least over the first year. SCI is associated with high costs which vary by country. This review was registered in PROSPERO (registration number: CRD42021235801).

Prediction of segmental motor outcomes in traumatic spinal cord injury: Advances beyond sum scores

Background and objectivesNeurological and functional recovery after traumatic spinal cord injury (SCI) is highly challenged by the level of the lesion and the high heterogeneity in severity (different degrees of in/complete SCI) and spinal cord syndromes (hemi-, ant-, central-, and posterior cord). So far outcome predictions in clinical trials are limited in targeting sum motor scores of the upper (UEMS) and lower limb (LEMS) while neglecting that the distribution of motor function is essential for functional outcomes. The development of data-driven prediction models of detailed segmental motor recovery for all spinal segments from the level of lesion towards the lowest motor segments will improve the design of rehabilitation programs and the sensitivity of clinical trials. MethodsThis study used acute-phase International Standards for Neurological Classification of SCI exams to forecast 6-month recovery of segmental motor scores as the primary evaluation endpoint. Secondary endpoints included severity grade improvement, independent walking, and self-care ability. Different similarity metrics were explored for k-nearest neighbor (kNN) matching within 1267 patients from the European Multicenter Study about Spinal Cord Injury before validation in 411 patients from the Sygen trial. The kNN performance was compared to linear and logistic regression models. ResultsWe obtained a population-wide root-mean-squared error (RMSE) in motor score sequence of 0.76(0.14, 2.77) and competitive functional score predictions (AUCwalker = 0.92, AUCself-carer = 0.83) for the kNN algorithm, improving beyond the linear regression task (RMSElinear = 0.98(0.22, 2.57)). The validation cohort showed comparable results (RMSE = 0.75(0.13, 2.57), AUCwalker = 0.92). We deploy the final historic control model as a web tool for easy user interaction (https://hicsci.ethz.ch/). DiscussionOur approach is the first to provide predictions across all motor segments independent of the level and severity of SCI. We provide a machine learning concept that is highly interpretable, i.e. the prediction formation process is transparent, that has been validated across European and American data sets, and provides reliable and validated algorithms to incorporate external control data to increase sensitivity and feasibility of multinational clinical trials.

Comparison of autonomic nervous system dysfunction, arterial stiffness, and heart rate recovery according to spinal cord injury level.

To investigate the differences in autonomic nervous system (ANS) dysfunction, arterial stiffness, and the degree of delay in post-exercise heart rate recovery (HRR) according to the level of spinal cord injury (SCI), and propose preventive measures against cardiovascular diseases after SCI. This retrospective study included 51 patients with SCI. Based on the neurological level of injury (NLI), patients were divided into two groups: Group A (NLI at and above T6) and Group B (NLI below T6). To assess ANS dysfunction, the head-up tilt test and 24-hour ambulatory blood pressure monitoring were conducted. Arterial stiffness was measured using the pulse wave velocity test. The exercise tolerance test was conducted to measure post-exercise HRR. Group A had significantly higher values in the head-up tilt test and 24-hour ambulatory blood pressure monitoring. In the pulse wave velocity test, both sides (left and right) had significantly higher values in Group B. One minute after the exercise tolerance test, Group A had significantly slower HRR (18.8 ± 11.1 beats/minute) than Group B. Understanding the impact of ANS dysfunction and arterial stiffness on HRR in SCI according to NLI may provide insights for clinical management and preventative strategies for cardiovascular diseases.

Development and validation of early prediction models for new-onset functional impairment of patients with trauma at hospital discharge.

Early identification of individuals at risk of functional impairment after trauma is crucial for the timely clinical decision-making and intervention to improve reintegration into the society. This study aimed to develop and validate models for predicting new-onset functional impairment after trauma using predictors that are routinely collected within 2 days of hospital admission. In this multicenter retrospective cohort study of acute care hospitals in Japan, we identified adult patients with trauma with independence in carrying out activities of daily living before hospitalization, treated in the intensive or high-dependency care unit, and survived for at least 2 days between April 2008 and September 2023. The primary outcome was functional impairment defined as Barthel Index ≤60 at hospital discharge. In the internal validation data set (between April 2008 and August 2022), using the routinely collected 129 candidate predictors within 2 days of admission, we trained and tuned the four conventional and machine learning models with repeated random subsampling cross-validation. We measured the performance of these models in the temporal validation data set (between September 2022 and September 2023). We also computed the importance of each predictor variable in our model. We identified 8,529 eligible patients. Functional impairment at discharge was observed in 41% of the patients (n = 3,506/8,529). In the temporal validation data set, all four models showed moderate discrimination ability, with areas under the curve above 0.79, and extreme gradient boosting showing the best performance (0.83). In the variable importance analyses, age was the most important predictor, followed by consciousness, severity score, cervical spinal cord injury, mild dementia, and serum albumin level at admission. We successfully developed early prediction models for patients with trauma with new-onset functional impairment at discharge that achieved high predictive performance using routinely collected data within 2 days of hospital admission. Prognostic/Epidemiological; Level II.

Effectiveness of respiratory management for mechanical ventilator weaning in traumatic spinal cord injury patients with prolonged ventilation

Background. Traumatic spinal cord injury is a medical condition which often results in disability and mortality. The most common lesion was cervical level, which is around 60-75% of all cases, where at this level there is a risk of respiratory problems which often require mechanical ventilation. Case report. In the case discussed, a 28-years-old male was referred from other hospital with traumatic cervical spinal cord injury (C5-C6) ASIA score A with a history of falling from a height of 3 meters. The patient underwent decompressive laminectomy on the tenth day of onset, followed by mechanical ventilation. During treatment, the patient received pharmacological therapy, tracheostomy, acupuncture, physiotherapy, and neuromuscular electrical stimulation for ventilator weaning. The patient was hospitalized for 66 days, with mechanical ventilation duration for 32 days. Conclusions. Factors that can influence the duration of ventilation weaning are the level and severity of spinal cord injury, time of transfer to a health facility, and complications related to ventilator installation. Multidisciplinary management, including pharmacological, physiotherapy, acupuncture, surgical, neuromuscular electrical stimulation, can increase the chances and decreasing the duration of mechanical ventilation, and reducing complications related to spinal cord injury and prolonged ventilation.

Postural effects on blood pressure, intraocular pressure, and ocular perfusion pressure in patients with spinal cord injury

Background Reduced ocular perfusion pressure (OPP) from hypotension and consistent OPP variability due to blood pressure (BP) fluctuations are predisposing factors for glaucoma. Low resting BP and orthostatic hypotension (OH) in spinal cord injury (SCI) patients may increase the risk of glaucoma post-injury. This study investigated BP, intraocular pressure (IOP), and OPP changes between supine and sitting positions in SCI and normal individuals. Methods Twenty SCI cases (high paraplegia, T1–T6 n = 6; low paraplegia, T7–L3 n = 14) and matched controls (1:1) were included. Systolic and diastolic BP (SBP and DBP) were measured digitally, and IOP with rebound tonometry. Measurements were taken one minute apart in both positions. Mean arterial pressure (MAP) was calculated, and OPP was determined using position-specific formulas. Results No SCI subjects exhibited OH. Both groups experienced significant BP increment (P < 0.05) from supine to sitting. SBP increased by 4.4 ± 8.4 mmHg (SCI) and 3.6 ± 6.2 mmHg (normal), while DBP increased by 4.2 ± 5.1 mmHg (SCI) and 6.7 ± 5.5 mmHg (normal). IOP and OPP decreased significantly (P < 0.05) after postural change in both groups, yet differences between them were not significant. Analysis by injury level revealed lower parameter values in high paraplegia than in low paraplegia, with the latter group showing a more significant reduction in OPP after postural change. Conclusion Postural changes differently affect BP, IOP, and OPP in SCI compared to normal individuals, with variations based on the level of SCI. While not directly assessing glaucoma, the study offers insights into ocular hemodynamics in SCI compared to normals.

Cord Injury and Ejaculatory Dysfunction in Young Men in a Third Level Hospital of Cali-Colombia

The level of spinal cord injury (SCI) has been associated with ejaculatory dysfunction and mortality. The relation of ejaculatory dysfunction with the severity of the SCI is not fully studied. Methods: A cross-sectional study was carried out in Cali, Colombia to evaluate aspects related to the sexuality of patients with SCI. Sociodemographic, clinical characteristics and sexual behavior were evaluated. A univariate, bivariate and multivariate analysis was performed. Results: 41 patients were evaluated. The mean age of the participants was 36.0±13.3 years old. 34 (82.9%) were male. 33 (80.5%) had cervical or thoracic lesions. 21 (53.7%) were by firearms. Most patients stated that the trauma kept them from engaging in satisfactory sexual activity in spite of having sexual desire. 16 (39.2%) had severe SCI (Type A, ASIA Scale). 40 (50.6%) had a severe compromise of their sexuality. 19 (46.3%) observed impossibility to ejaculate. Of the male patients, 19 (55.9%) had no ejaculation, with no differences according to the level of lesion, however, there was a difference in ejaculatory involvement according to the type of lesion (78.9% in type A, 42.86% in type C and 0% in type E) (p &lt; 0.05). Conclusions: Spinal cord injury was more frequent in young male population, mainly with cervical or thoracic lesions by firearms. In patients with SCI the impossibility to ejaculate was observed only according to the severity and type of lesion and no with the level of the lesion.

A moderate spinal contusion injury in rats alters bone turnover both below and above the level of injury with sex-based differences apparent in long-term recovery

Spinal cord injury (SCI) leads to significant sublesional bone loss and high fracture rates. While loss of mechanical loading plays a significant role in SCI-induced bone loss, animal studies have demonstrated mechanical loading alone does not fully account for loss of bone following SCI. Indeed, we have shown that bone loss occurs below the level of an incomplete moderate contusion SCI, despite the resumption of weight-bearing and stepping. As systemic factors could also impact bone after SCI, bone alterations may also be present in bone sites above the level of injury. To examine this, we assessed bone microarchitecture and bone turnover in the supralesional humerus in male and female rats at two different ages following a moderate contusion injury in both sub-chronic (30 days) and chronic (180 days) time points after injury. At the 30-day timepoint, we found that both young and adult male SCI rats had decrements in trabecular bone volume at the supralesional proximal humerus (PH), while female SCI rats were not different from age-matched shams. At the 180-day timepoint, there were no statistical differences between SCI and sham groups, irrespective of age or sex, at the supralesional proximal humerus. At the 30-day timepoint, all SCI rats had lower BFR and higher osteoclast-covered trabecular surfaces in the proximal humerus compared to age-matched sham groups generally matching the pattern of SCI-induced changes in bone turnover seen in the sublesional proximal tibia. However, at the 180-day timepoint, only male SCI rats had lower BFR at the supralesional proximal humerus while female SCI rats had higher or no different BFR than their age-matched counterparts. Overall, this preclinical study demonstrates that a moderate contusion SCI leads to alterations in bone turnover above the level of injury within 30-days of injury; however male SCI rats maintained lower BFR in the supralesional humerus into long-term recovery. These data further highlight that bone loss after SCI is not driven solely by disuse. Additionally, these data allude to potential systemic factors exerting influence on bone following SCI and highlight the need to consider treatments for SCI-induced bone loss that impact both sublesional and systemic factors.

254 Initiation of Low Molecular Weight Heparin Within 24 Hours Is Safe and Effective for VTE Prophylaxis in Spinal Cord Injury Patients

INTRODUCTION: Venous thromboembolism (VTE) following traumatic spinal cord injury (SCI) is a major clinical concern. Current guidelines recommend initiation of chemical prophylaxis within 72 hours of injury or surgery. Given the high reported incidence of VTE in this population, the safety and efficacy of earlier initiation is an important clinical question. METHODS: We analyzed prospectively collected data in a cohort of 162 SCI patients from a single quaternary center. Demographic and clinical data were recorded. Univariate and multivariate logistic regression analyses were performed to identify predictors of VTE in SCI patients treated with LMWH within 24 hours of injury or surgery. RESULTS: Mean age was 56.9 years (28% females). One hundred and thirty (87.8%) patients underwent SCI surgery. There was an extremity fracture in 18.2% and lumbar drain was placed in 22.3%. DVT occurred in 7.4%, PE in 6.1%, and any VTE in 12.2%. A multivariable regression model including age, sex, race, injury severity score, level of SCI, SCI surgery status, admission lower extremity motor score, and extremity fracture showed that only lower extremity motor score (OR 0.94, p=0.03) was significantly associated with VTE. There were 1.5% patients with post-SCI surgery-related bleeds requiring surgery takeback. There were 5.6% non-surgery related bleeds, and 1.2% wound dehiscence. CONCLUSIONS: Initiation of LMWH within 24 hours of injury or surgery maintained the incidence of any VTE event within the lower end of previously reported ranges with 1.5% of patients who underwent SCI surgery requiring surgery takeback due to bleeding complications. Admission lower extremity motor score was the sole predictor of VTE in this patient cohort.

Identification and assessment of Electronic Aids for Daily Living considered essential by persons with high level tetraplegia: a case series

Although assistive technology (AT) is recognized as a basic human right, access to AT, and particularly electronic aids to daily living (EADL), is limited. We aimed to understand how persons with high level spinal cord injury (SCI) prioritize EADL needs and assess satisfaction and efficacy of self-identified EADL. Thus, in this case series, we recruited three participants with C4, C5 or C6 SCI receiving in-patient SCI rehabilitation. Each received dedicated occupational therapy-based assistance in identifying EADL items within an unrestricted envelope of support ($5000 CDN) for use in maximizing physical independence and supporting their return to community-based living. Items identified were categorized by need (emergency/security; home environment control; or virtual access to the outside world). Each participant selected distinct EADL. Evaluation of selected EADL items indicated very high satisfaction. The selected EADL contributed to participants’ returns to employment, community life, or reduced requirements for attendant services. These findings suggest that identification of essential technology should reflect the unique needs of each person and the context in which it will be used. These findings also support use of mainstream technology to meet EADL needs of individuals with limited physical abilities.

Spinal Cord Tethering after Trauma and Impact of Age and Surgical Outcome

Introduction: Spinal cord tethering, a condition where the spinal cord becomes attached or fixed to surrounding tissues, can occur following trauma, leading to a range of neurological deficits and complications. Objectives: The main objective of the study is to find the spinal cord tethering after trauma and impact of age and surgical outcome in local population of Pakistan. Material and methods: This retrospective study was conducted in Ayub Medical Complex Abbottabad from January 2023 to August 2023. Data was collected from 50 patients of spinal cord tethering patients. Data collection involved a comprehensive review of the medical records of patients. Relevant demographic information, including age at the time of trauma, gender, and comorbidities, was extracted. Clinical details such as mechanism of injury, level and severity of spinal cord injury, duration of symptoms and preoperative neurological status were documented. Results: Data were collected from 50 SCI patients. The mean age of the patients was 45 ± 10.5 years and there were 60% male and 40% female patients. The most common mechanisms of injury were motor vehicle accidents (50%), followed by falls (30%) and sports-related injuries (20%). Regarding the spinal level affected, the majority of injuries were cervical (60%), followed by thoracic (30%) and lumbar (10%). Neurological improvement was observed in 40% of patients, with complete improvement in 40% and partial improvement in 20%, while 40% showed no improvement. Complications were reported in a subset of patients, with cerebrospinal fluid leaks occurring in 15%, wound infections in 10%, and other complications in 5% of cases. Reoperation was necessary in 10% of patients, while 90% did not require further surgical intervention. Age and neurological improvement showed non-significant differences between groups (p &gt; 0.05), while length of hospital stay differed significantly (p = 0.018). Complications and functional improvement did not vary significantly between groups (p &gt; 0.05) Practical Implication: This study's practical implications offer vital benefits to the community. The identification of age as a critical component in spinal cord tethering after trauma enables healthcare practitioners to more accurately evaluate risk and customize therapies. Furthermore, our research emphasizes how successful surgical therapies are for patients of all ages, giving patients confidence in their available treatment alternatives. Further improving patient care is pushing for individualized treatment options and being aware of related consequences. Conclusion: It is concluded that age influences the occurrence of spinal cord tethering following trauma, with older patients being more susceptible to this complication. However, surgical intervention appears to be equally effective across age groups, with comparable rates of neurological improvement and complications.

Radiology diagnostics of spinal corel injury in early children: a prospective study

INTRODUCTION: Spinal cord injury (SCI) in young children includes a relatively higher prevalence of cervical spine injury, multiple thoracic vertebral compression fractures, and spinal cord injury. Spinal cord injuries without radiological changes/signs of fractures or dislocations (SCIWORA) also occur in young children. X-ray assessment of damage to immature vertebrae and cartilage in young children is difficult, since incompletely formed vertebral bodies can be confused with fractures. Accordingly, an MRI is required, which provides a detailed anatomical image of all structures of the spinal column and also diagnoses damage to the spinal cord, ligaments and muscles.OBJECTIVE: To investigate the possibilities of methods of radiation diagnosis of spinal cord injury in young children (up to 3 years).MATERIAL AND METHODS: 20 children aged from 11 months up to 3 years old were studied with spinal cord injury. X-ray, computed tomography (CT) and magnetic resonance imaging (MRI) were performed. The standard MRI protocol for SCI in children under 3 years of age included: MR myelography in the coronary and sagittal projections, sagittal projection STIR, DTI and T2WI FS SE, axial projection T2WI FS SE or T2*WI FS GE; coronary projection T2WI SE; 3D T1WI FS GE before and after contrast enhancement.RESULTS: An analysis of the data of patients included in the category of polytrauma was carried out. The causes of SCI in these patients were road accidents and falls from various heights. X-ray and CT scans were uninformative, and had large discrepancies with MRI results. All anatomical and morphological changes revealed by MRI correlated well with clinical manifestations and corresponded to the classification of the level and severity of spinal cord injury (ASIA). An increase in the volume and change in the signal of the spinal cord due to edema and / or hemorrhage in the spinal cord is the main sign of damage to the spinal cord, and is best indicated on T2WI and STIR, as a hyperintense signal.DISCUSSION: MRI is critical in the emergency assessment of spinal cord injury or compression to predict the outcome of SCI. There is currently no spinal cord imaging technique that can compete with MRI. Increased volume and signal changes in the spinal cord due to edema and/or hemorrhage are a sign of spinal cord injury and are best demonstrated on T2WI and STIR as a hyperintense signal. Incomplete spinal cord injury is also manifested by a hyperintense signal on T2WI and/or FLAIR, which in intensity and extent correlates with the degree of injury. Hemorrhagic injuries are better detected using T2*GRE or SWI, and spinal cord edema is better detected using T2WI SE and STIR. In addition, STIR can identify bone marrow edema in injured vertebrae, even when the injury is not detected on CT.CONCLUSION: When performing MRI in patients with SCI, three quantitative parameters should be assessed: the maximum damage to the spinal cord, the maximum compression of the spinal cord, and the length of the affected area. In addition to the results of quantitative parameters, potential predictive qualitative MRI findings should be evaluated such as intramedullary hemorrhage, focal and diffuse spinal cord edema, soft tissue injury, probable stenosis before injury, and disc herniation.

Relationship between employment and quality of life and self-perceived health in people with spinal cord injury: an international comparative study based on the InSCI Community Survey.

Cross-sectional study. Work-related disability is common in persons with spinal cord injury (SCI). The aims of this study are to examine the associations of employment with self-perceived health (SPH) and quality of life (QoL) across 22 countries and to explore the covariates around employment and SPH and QoL. Community. We analyzed 9494 community-dwelling persons with SCI aged 18-65. We performed an adjusted regression and path analysis. The independent variable was 'employment' and the dependent variables were two single items: QoL (very poor to very good) and SPH (excellent to poor). Covariates included the Gross Domestic Product (GDP), education, time since SCI, age, gender, years of employment after SCI, SCI level (paraplegia, tetraplegia), and completeness of SCI. Participants' mean age was 47, 74% were male, and 63% had paraplegia. We found an association between employment and QoL and SPH. While the magnitude of the effect of employment on QoL did not differ across GDP quartiles, its perceived effect on QoL was found to be significant in the highest GDP quartile. Employment was predictive of good SPH in two GDP quartiles (Q1 and Q4), but significant across all quartiles when predicting poor perceptions, with the magnitude of effect varying significantly. Employment is closely related to QoL and SPH depending on the GDP. We may positively influence the QoL and SPH in the SCI population to promote better employment outcomes by considering the infrastructure and economy.

Characterizing neurological status in individuals with tetraplegia using transcutaneous spinal stimulation

Transcutaneous spinal stimulation (TSS) is emerging as a valuable tool for electrophysiological and clinical assessment. This study had the objective of examining the recruitment patterns of upper limb (UL) motor pools through the delivery of TSS above and below a spinal lesion. It also aimed to explore the connection between the recruitment pattern of UL motor pools and the neurological and functional status following spinal cord injury (SCI). In eight participants with tetraplegia due to cervical SCI, TSS was delivered to the cervical spinal cord between the spinous processes of C3–C4 and C7–T1 vertebrae, and spinally evoked motor potentials in UL muscles were characterized. We found that responses observed in UL muscles innervated by motor pools below the level of injury demonstrated relatively reduced sensitivity to TSS compared to those above the lesion, were asymmetrical in the majority of muscles, and were dependent on the level, extent, and side of SCI. Overall, our findings indicate that electrophysiological data acquired through TSS can offer insights into the extent of UL functional asymmetry, disruptions in neural pathways, and changes in motor control following SCI. This study suggests that such electrophysiological data can supplement clinical and functional assessment and provide further insight regarding residual motor function in individuals with SCI.

Healthcare Experience of People with Acute Spinal Cord Injury: A Phenomenological Study.

Living with spinal cord injury (SCI) is a challenge that begins in the acute phase, when the disease, the limitations, and the treatments fill the days at the hospital. This study aims to understand the healthcare experience of the person with SCI in the acute phase, based on the Activities of Living Nursing Model (ALNM). It is a qualitative and phenomenological study based on the Standards for Reporting Qualitative Research. Data were collected via semi-structured interviews. Content analysis was performed using the ATLAS.ti software and Bardin's methodology. The article was written following the COREQ guidelines. The categories were defined using the Roper-Logan-Tierney Model for Nursing. The sample included 16 people with incomplete SCI, different etiology, and neurological levels. Eleven of the twelve ALNM emerged from the interviews. The activities of mobilizing, eliminating, maintaining a safe environment, and communicating were emphasized the most. Controlling body temperature was not relevant. Mobility deficits and pain increased dependence. Feelings of motivation, encouragement, and frustration were highlighted. Professional expertise, rehabilitation resources, and support equipment promoted independence. The results in this sample revealed that people with SCI in the acute phase have complex challenges related to dependence awareness and treatments, but they always keep recovery expectations in mind.
