Frequency and age effects of secondary health conditions in individuals with spinal cord injury: a scoping review

The Effect of Concomitant Spinal Cord Injury on Postoperative Health-related Quality of Life After Traumatic Subaxial Cervical Spine Injuries: A Nationwide Registry Study

OBJECTIVE

To evaluate the effect of spinal cord injury (SCI) on the health-related quality of life (HRQoL) in patients surgically treated for traumatic subaxial cervical spine injuries and investigate the agreement between objective neurologic outcomes and patient reported outcome measures (PROMs) in that context.

STUDY DESIGN

Observational study on prospectively collected multi-institutional registry data.

SETTING

Sweden.

PARTICIPANTS

Patients with traumatic subaxial spine injuries identified in the Swedish Spine Registry (Swespine) between 2006 and 2016.

INTERVENTIONS

Anterior, posterior, or anteroposterior cervical fixation surgery.

MAIN OUTCOMES

Patient-reported outcome measures (PROMs) consisting of EQ-5D-3Lindex and Neck Disability Index (NDI).

RESULTS

Among the 418 identified patients, 93 (22%) had a concomitant SCI. In this group, 30 (32%) had a complete SCI (Frankel A), and the remainder had incomplete SCIs (17%) Frankel B; 25 (27%) Frankel C; 22 (24%) Frankel D. PROMs significantly correlated with the Frankel grade (P<.001). However, post hoc analysis revealed that the differences between adjacent Frankel grades failed to reach both statistical and clinical significance. On univariable linear regression, the Frankel grade was a significant predictor of a specific index derived from the EQ-5D-3L questionnaire (EQ-5D-3Lindex) at 1, 2, and 5 years postoperatively as well as the NDI at 1 and 2 years postoperatively (P<.001). Changes of PROMs over time from 1, to 2, and 5 years postoperatively did not reach statistical significance, regardless of the presence and degree of SCI (P>.05).

CONCLUSION

Overall, the Frankel grade significantly correlated with the EQ-5D-3Lindex and NDI and was a significant predictor of PROMs at 1, 2, and 5 years. PROMs were stable beyond 1 year postoperatively regardless of the severity of the SCI.

Health care needs and health services utilization of people with spinal cord injury living in Jiangsu and Sichuan provinces of China: a cross-sectional community survey

PURPOSE

We aimed to investigate health care needs, health service utilization, and their socio-economic and health-related determinants in people with spinal cord injury (SCI) living in Jiangsu and Sichuan Provinces of China.

MATERIALS AND METHODS

A total of 1355 participants with SCI living in the community were recruited using a multi-stage stratified random sample and surveyed by telephone or online. Outcomes evaluated included the presence of health care needs, mode of health service utilization, and specific provider types seen within 12 months preceding the survey.

RESULTS

The prevalence of healthcare needs was 92%. Needs were higher in Sichuan (98%) as compared to Jiangsu (80%). Of those in need of health care, 38% reported not having utilized care, more in Sichuan (39%) than in Jiangsu (37%). In Jiangsu, inpatient care was more often used than in Sichuan (46% vs. 27%), while in Sichuan outpatient services were utilized more often (33% vs. 17%). On average, 1.6 provider types were seen, with Sichuan reporting fewer different provider types.

CONCLUSIONS

Considerable differences in the prevalence of health care needs and service utilization patterns were found between provinces, mostly in favour of the economically more developed Jiangsu Province.Implications for RehabilitationPeople with low income, particularly those below the World Bank poverty line for middle-income countries, had increased health care needs but utilized health care less often.Moreover, environmental barriers contributed significantly to unmet health care needs.This implies the necessity to provide better accessible and more affordable rehabilitation services for people with spinal cord injury (SCI) in China such as community-based rehabilitation programming.Policies for alleviation of poverty in the case of SCI including insurance for catastrophic health expenditure should also be reviewed and adapted where applicable.

Seeking sufficient and appropriate care during the first year after spinal cord injury: a qualitative study

STUDY DESIGN

Longitudinal qualitative study, based on a constructivist grounded theory and transformative approach.

OBJECTIVES

This study investigated experiences of individuals with spinal cord injury (SCI) while navigating rehabilitation, resources for recovery, and community reintegration during the first year after injury.

SETTING

An acute inpatient rehabilitation facility in the Midwest United States.

METHODS

In-depth, semi-structured interviews were conducted with 20 individuals with newly-acquired SCI. Interviews were conducted approximately every other month for one year, beginning at acute inpatient rehabilitation. Data were analyzed and interpreted using a constructivist grounded theory approach and transformative paradigm, which examines power and social structures within and across institutions and gives voice to people at risk for marginalization.

RESULTS

Participants experienced variable post-injury trajectories, with an average of four transitions within and across healthcare institutions in the first three months. Half of the cohort was discharged to a skilled nursing facility (SNF). Emergent themes included discharge (un)readiness; length of stay uncertainty and insurance impacts; challenges choosing a SNF including time-sensitive decisions; and early cessation of therapy in the SNF. Participants experienced resource navigation challenges such as communication/information access barriers and contending with many concerns at once.

CONCLUSIONS

The experiences of this cohort reveal significant challenges to attaining sufficient and appropriate rehabilitation. Acute inpatient rehabilitation is a critical aspect of recovery, but does not ensure sufficient intervention for maximization of functional skills and community reintegration. Innovative rehabilitation models need to be developed for positive impacts on successful transition to independent living in the community.

Relationship of cardiometabolic disease risk factors with age and spinal cord injury duration

CONTEXT/OBJECTIVES

Cardiometabolic disease (CMD) is increased after spinal cord injury (SCI), with an increased number of CMD risk factors that relate to higher mortality. The study objective was to characterize the relationship of age and injury duration with CMD.

DESIGN

Retrospective cohort assessment of CMD risks using unbiased recursive partitioning to divide for group comparison: (1) Lowest Risk, (2) Moderate Risk, and (3) Highest Risk based on classification and regression trees predicting CMD diagnosis by age and injury duration.

SETTING

Academic rehabilitation center laboratory.

PARTICIPANTS

Adults (N = 103; aged 18-75) with traumatic SCI (C4-L2) of 3 months to 42 years duration.

INTERVENTIONS

NA.

OUTCOME MEASURES

CMD risk factors (obesity, insulin resistance, dyslipidemia, and hypertension) using Paralyzed Veterans of America SCI-specific guidelines.

RESULTS

Obesity was prevalent (82%) and co-occurred with most other risk factors present. Age increased odds for CMD diagnosis by 1.05 per year (P = 0.02) and was directly related to elevated body mass index (BMI, β = 0.42, P < 0.05), fasting glucose (β =  0.58, P < 0.01), and higher systolic blood pressure (β = 0.31, P < 0.10). In contrast, time since injury contributed to lower risk factor count (β = -0.29, P < 0.10) and higher HDL-C (β = 0.50, P < 0.01), and was not related to odds of CMD diagnosis.

CONCLUSION

While SCI is linked to an increased risk of CMD, age is associated with higher CMD risk. Increased SCI duration related to improvement in individual CMD risk factors but did not decrease overall risk for CMD diagnosis. SCI may not uniformly increase CMD risks and highlight a necessary focus on weight management for risk prevention.

Do individuals from an SCI-specialized rehabilitation facility have fewer secondary health conditions than those from a non-SCI-specialized rehabilitation facility? Analysis of the InSCI database from a middle-income country

OBJECTIVES

To determine whether attending an SCI-specialized rehabilitation facility (SSRF) is independently associated with having fewer secondary health conditions (SHCs) in middle-income country contexts.

STUDY DESIGN

Cross-sectional observational study.

SETTING

Four rehabilitation facilities in Thailand (one SSRF and three non-SSRF).

METHODS

Data from a Thai arm of the International Spinal Cord Injury Community Survey (InSCI) were analyzed. SHCs occurring within the last three months were evaluated using the Spinal Cord Injury Secondary Condition Scale. A causal diagram was applied to create a multivariable regression model to determine the independent effect of attending in the SSRF on having SHC as a single condition and as a sum score.

RESULTS

Three hundred and thirteen individuals with chronic SCI were included in this study. Two hundred and nineteen participants (70%) were recruited from the SSRF. Being recruited from the SSRF was an independent negative correlating factor of the SHC sum score with an unstandardized coefficient of -1.12 (95% CI: -2.00-0.24). Being recruited from the SSRF was also an independent negative correlating factor of having bladder dysfunction, sexual dysfunction, and pressure ulcer SHC with an odds ratio of 0.32 (95% CI: 0.16-0.59), 0.43 (95% CI: 0.22-0.84), and 0.46 (95% CI: 0.24-0.89), respectively.

CONCLUSION

Attending an SSRF was significantly associated with having fewer SHCs, specifically, bladder dysfunctions, sexual dysfunctions, and pressure ulcers. These results suggest the importance of having SSRF in middle-income countries for delivering effective care to people with SCI and standardized education to health care providers.

Difficulty Obtaining Daily Necessities and Difficulty Obtaining SCI Services During the COVID-19 Pandemic Among People With Spinal Cord Injury

OBJECTIVE

To describe the self-reported difficulties during the COVID-19 pandemic on the lives of persons with traumatic spinal cord injury (SCI), and to identify the factors measured prior the pandemic that predict the number of difficulties obtaining daily necessities and difficulties obtaining SCI services during the pandemic.

DESIGN

Cohort study.

SETTING

A state SCI outcomes follow-up database in the southeastern United States.

PARTICIPANTS

297 participants (N=297) met the following eligibility criteria: (1) ≥18 years of age, (2) traumatic SCI, (3) minimum of 1-year post-injury, and (4) having completed a longitudinal study questionnaire immediately prior to the pandemic (between 12/1/2019 and 03/11/2020).

INTERVENTIONS

N/A.

MAIN OUTCOME MEASURE(S)

The outcome measures were the self-reported number of difficulties obtaining daily necessities (difficulties to get food, medication, and routine medical/dental care) and difficulties obtaining SCI services during the pandemic (difficulties to get treatment for SCI-related problems, to maintain regular SCI equipment, and to get SCI supplies).

RESULTS

Among 297 eligible participants, 247 (83%) have completed the follow-up during the pandemic between December 2020 and December 2021. There were 22% participants having at least 1 difficulty obtaining daily necessities and 19% participants having at least 1 difficulty obtaining SCI services. Younger, ambulatory participants, cervical 1-4 injury level, lower household income, more health conditions, and no routine health care access prior to the pandemic were associated with greater number of difficulties obtaining daily necessities. Women, non-ambulatory participants, marital relation, having need for physical assistance, more health conditions, and no routine health care access prior to the pandemic related to greater number of difficulties obtaining SCI services.

CONCLUSIONS

People with SCI have experienced living difficulties during the COVID-19 pandemic. Of particular importance, no routine health care access and more health conditions are related to more difficulties obtaining both daily necessities and SCI services after controlling the socio-demographics and injury characteristics.

Use of professional home care in persons with spinal cord injury in Switzerland: a cross-sectional study

BACKGROUND

Persons with spinal cord injury (SCI) living in the community often require care. The boundaries between professional home care and informal care are blurred, and it is unclear who the typical user of home care is. The objective of this study was to describe the characteristics of persons with SCI using professional home care in Switzerland, determine the frequency of home care visits, and investigate the association of sociodemographic factors, SCI-specific characteristics, secondary health conditions, and functional independence with the use of home care.

METHODS

We used cross-sectional data from the 2017 community survey of the Swiss Spinal Cord Injury Cohort Study (SwiSCI). Out of 3,959 eligible individuals 1294 completed the questionnaire and were included in the analysis (response rate 33%). Using descriptive statistics, differences between home care users and non-users as well as the frequency of home care visits were investigated. The association between sociodemographic factors, SCI-specific characteristics, secondary health conditions, functional independence and the use of home care was analyzed using multivariable logistic regression. Multiple imputation was used to account for missing data.

RESULTS

Of 1,294 participants, 280 (22%) used professional home care. The median weekly professional home care duration was 6 h (Q1 = 2, Q3 = 12). More home care was used in persons with lower functional independence (Odds ratio (OR) 0.30 per 10 unit decrease in the Spinal Cord Independence Measure, 95%-Confidence interval (CI) 0.24-0.37), fewer secondary health conditions (OR 0.96 per unit Spinal Cord Injury Secondary Conditions Scale, 95%-CI 0.94-0.99), tetraplegia (OR 2.77, 95%-CI 1.92-4.00), women (OR 2.42, 95%-CI 1.70-3.43), higher age (OR 1.22 per 10 years increase, 95%-CI 1.06-1.39), living alone (OR 2.48, 95%-CI 1.53-4.03), and those receiving support from an informal caregiver (OR 1.88, 95%-CI 1.27-2.77).

CONCLUSIONS

This is the first study to examine the use of professional home care from the perspective of persons with SCI in Switzerland. Lower functional independence strongly predicts increased home care use. The findings showed that professional home care complements informal care and is more likely to be used by individuals with SCI who live alone, have tetraplegia, and are female.

Effects of Adaptations in an Interdisciplinary Follow-Up Clinic for People with Spinal Cord Injury in the Chronic Phase: A Prospective Cohort Study

People with spinal cord injury (SCI) often experience secondary health conditions (SHCs), which are addressed during interdisciplinary follow-up clinics. We adapted the design of our clinic, by introducing a questionnaire concerning functioning and SHCs, additional measurements of blood pressure and saturation, and participants were seen by either a specialized nurse or rehabilitation physician. In this study, we investigated the effects of these adaptations and the experienced satisfaction of the participants. The results showed an increased number of recommendations in the adapted design, compared to the initial design. Further, the nature of the recommendations shifted from somatic issues to recommendations regarding psychosocial functioning and regarding (the use of) devices. The added measurements revealed an average high systolic blood pressure, which led to more referrals to the general practitioner. The clinical weight and pulmonary functions stayed stable over time. The current adaptations in design expanded and optimized the number and nature of recommendations regarding SHCs to participants. The questionnaire helps the participant to prepare for the clinic and the professionals to tailor their recommendations, resulting in highly satisfied participants.

Leisure, Recreation, and Life Satisfaction: A Longitudinal Study for People With Spinal Cord Injury

Background

Leisure and recreation (LR) are positively associated with social integration and life satisfaction in people with spinal cord injury (SCI). However, few studies have longitudinally observed long-term changes in LR participation among people with SCI and discussed the association of these activities with social integration and life satisfaction.

Objectives

This study aims to determine for people with SCI, within a 45-year period, the association between mobility and LR participation; the associations between LR participation and social integration and life satisfaction, respectively; and whether the association between LR participation and life satisfaction is mediated by social integration.

Methods

Growth modeling and linear mixed modeling were employed as the primary data analysis tools to explore longitudinal changes in LR participation, social integration, and life satisfaction. A mediation test was conducted to examine the potential mediation effect of social integration on the relationship between LR participation and life satisfaction.

Results

The mobility level, LR participation hours, and social integration of people with SCI decreased gradually during the 45-year period, whereas life satisfaction increased as they lived longer with the injury. LR participation was consistently and positively associated with social integration and life satisfaction of people with SCI. A mediation effect by social integration was observed between LR and life satisfaction.

Conclusion

A decline in mobility level was associated with a decrease in LR participation over time for people with SCI. Engaging in LR activities regularly and maintaining a certain level of social interaction are consistently and positively associated with long-term life satisfaction.

Perspectives on Data Sharing in Persons With Spinal Cord Injury

Open data sharing of clinical research aims to improve transparency and support novel scientific discoveries. There are also risks, including participant identification and the potential for stigmatization. The perspectives of persons participating in research are needed to inform open data-sharing policies. The aim of the current study was to determine perspectives on data sharing in persons with spinal cord injury (SCI), including risks and benefits, and types of data people are most willing to share. A secondary aim was to examine predictors of willingness to share data. Persons with SCIs in the United States and Canada completed a survey developed and disseminated through various channels, including our community partner, the North American Spinal Cord Injury Consortium. The study collected data from 232 participants, with 52.2% from Canada and 42.2% from the United States, and the majority completed the survey in English. Most participants had previously participated in research and had been living with an SCI for ≥5 years. Overall, most participants reported that the potential benefits of data sharing outweighed the negatives, with persons with SCI seen as the most trustworthy partners for data sharing. The highest levels of concern were that information could be stolen and companies might use the information for marketing purposes. Persons with SCI were generally supportive of data sharing for research purposes. Clinical trials should consider including a statement on open data sharing in informed consents to better acknowledge the contribution of research participants in future studies.

Factors enabling comorbidities and secondary conditions in older adults with spinal cord injury

OBJECTIVE

To examine the role of personal, social, and environmental factors predicting comorbidities and secondary conditions among older adults with spinal cord injury (SCI).

DESIGN

Cross-sectional study utilizing survey methods were used to collect the data analyzed with two distinct general linear models.

SETTING

Community-dwelling participants who resided in rural and urban areas.

PARTICIPANTS

One hundred and eighty-three (183) participants with SCI ages 45 and over at least five years post injury.

INTERVENTIONS

Not applicable.

MEASURES

Spinal Cord Injury Secondary Conditions Scale (SCI-SCS); Comorbidities Questionnaire; Spinal Cord Injury Functional Index Assistive Technology (SCI-FI/AT) Basic - Mobility; Spinal Cord Injury Quality of Life (SCI-QOL) Satisfaction with Social Roles and Activities Scale (SSRA); Cohen's Social Network-Social Integration Index, the Medical Outcomes Study (MOS) Social Support Emotional/Informational Support Scale, and the Facilitators and Barriers Survey for Mobility (FABS-Mv2). Questions were also asked from the Behavioral Risk Factor Surveillance System (BRFSS).

RESULTS

Common predictors of comorbidities and secondary conditions included age, basic mobility, primary health care payer and parking limitations. An interaction between parking and neurological classification was observed for comorbidities. Neurological classification and employment were significantly associated with comorbidities while for secondary conditions, sex, years since injury, education, satisfaction with social roles and the home environment were critical factors.

CONCLUSIONS

Our study shows the effects of demographic and injury factors, physical functioning, satisfaction with social roles, access to home environment adaptations and health resources in predicting comorbidities and secondary conditions among older adults with SCI.

Spinal cord injury and prescribed opioids for pain: a scoping review

OBJECTIVE

Spinal cord injury (SCI) is a life-altering neurological condition affecting physical and psycho-social functioning and associated high rates of pain. Thus, individuals with SCI may be more likely to be exposed to prescription opioids. A scoping review was conducted to synthesize published research findings on post-acute SCI and prescription opioid use for pain, identify literature gaps, and propose recommendations for future research.

METHODS

We searched 6 electronic bibliographic databases (PubMed [MEDLINE], Ovid [MEDLINE], EMBASE, Cochrane Library, CINAHL, PsychNET) for articles published from 2014 through 2021. Terms for "spinal cord injury" and "prescription opioid use" were used. Included articles were in English and peer reviewed. Data were extracted using an electronic database by 2 independent reviewers. Opioid use risk factors for chronic SCI were identified and a gap analysis was performed.

RESULTS

Of the 16 articles included in the scoping review, a majority were conducted in the United States (n = 9). Most articles lacked information on income (87.5%), ethnicity (87.5%), and race (75%). Prescription opioid use ranged from 35% to 64% in articles reporting this information (n = 7 articles, n = 3675 participants). Identified risk factors for opioid use included middle age, lower income, osteoarthritis diagnosis, prior opioid use, and lower-level spinal injury. Limited reporting of diversity in study populations, absence of risk of polypharmacy, and limited high quality methodology were identified gaps.

CONCLUSIONS

Future research should report data on prescription opioid use in SCI populations, with additional demographics such as race, ethnicity, and income, given their importance to risk outcomes.

Aging with spinal cord injury: A narrative review of consequences and challenges

Given the increase in life expectancy, aging with a pre-existing spinal cord injury (SCI) is becoming more common. This condition is challenging as compromised health status and functional independence can worsen. We aimed to provide an updated overview of the consequences of aging with SCI, highlighting the main challenges facing this population in a narrative review of the current literature we retrieved from the PubMed database from 2000 to 2022 on any aspect related to aging in persons with SCI. Here we address adverse circumstances that increase disability and hinder an active lifestyle, such as progressive physical deterioration, secondary health conditions, limitations in personal activity, changes in family and social support structures, aging of caregivers, and depletion of economic resources. Favorable changes are also observed, including psychosocial adjustments that improve quality of life. Additionally, various interventions are discussed to promote well-being, health, and social participation. Due to the relevance of this issue, people with SCI and all those who take care of them must have up-to-date information to carry out the necessary measures to promote healthy aging in a more inclusive social environment.

Responsiveness of the International Spinal Cord Injury Quality of Life Basic Data Set V2.0: An international longitudinal study

CONTEXT/OBJECTIVE

Examine the sensitivity of the International Spinal Cord Injury Quality of Life Basic Data Set V2.0 (QoL-BDS V2.0) to reflect changes in mobility and secondary health conditions (SHCs) between inpatient rehabilitation and one-year follow-up.

DESIGN

International longitudinal study. Questionnaires were administered at baseline (Median 6 weeks, inter-quartile range 4-10 weeks post-onset) and after 12 months.

SETTING

Spinal cord rehabilitation institutions in the US, Brazil, Australia and the Netherlands.

PARTICIPANTS

: Individuals with recent onset of spinal cord injury or disease (SCI/SCD) admitted to inpatient rehabilitation.

OUTCOME MEASURES

The QoL-BDS V2.0, comprises four items on satisfaction with 'life as a whole', 'physical health', 'psychological health', and 'social life'. Mobility level was measured with a single item and SHCs with the SCI Secondary Conditions Scale (SCI-SCS).

RESULTS

Of the 160 participants, 61% had SCI, 48% had tetraplegia and 82% were wheelchair-users. Scores on 'life as a whole', 'physical health' and the total scale were significantly higher at follow-up compared to baseline in the total sample and the SCD subgroup, but not in the SCI subgroup. Increases in 'physical health', 'psychological health', 'social life' and the total score were significantly associated with improvements in the SCI-SCS or mobility scores. Participants with improved SCI-SCS and mobility at follow-up showed significantly more improvement in satisfaction with social life and the total score compared to participants without such favorable changes.

CONCLUSION

The results of this study provide partial evidence of responsiveness of the QoL-BDS V2.0 total score as a measure of QoL among individuals with SCI/SCD.

Multimorbidity in persons with non-traumatic spinal cord injury and its impact on healthcare utilization and health outcomes

STUDY DESIGN

Cross-sectional survey in Canada.

OBJECTIVES

To explore multimorbidity (the coexistence of two/more health conditions) in persons with non-traumatic spinal cord injury (NTSCI) and evaluate its impact on healthcare utilization (HCU) and health outcomes.

SETTING

Community-dwelling persons.

METHODS

Data from the Spinal Cord Injury Community Survey (SCICS) was used. A multimorbidity index (MMI) consisting of 30 secondary health conditions (SHCs), the 7-item HCU questionnaire, the Short Form-12 (SF-12), Life Satisfaction-11 first question, and single-item Quality of Life (QoL) measure were administered. Additionally, participants were grouped as "felt needed healthcare was received" (Group 1, n = 322) or "felt needed healthcare was not received" (Group 2, n = 89) using the HCU question. Associations among these variables were assessed using multivariable analysis.

RESULTS

408 of 412 (99%) participants with NTSCI reported multimorbidity. Constipation, spasticity, and fatigue were the most prevalent self-reported SHCs. Group 1 had a higher MMI score compared to Group 2 (p < 0.001). A higher MMI score correlated with the feeling of not receiving needed care (OR 1.4, 95% CI 1.08-1.21), lower SF-12 (physical/mental component summary scores), being unsatisfied with life, and lower QoL (all p < 0.001). Additionally, Group 1 had more females (p < 0.001), non-Caucasians (p = 0.034), and lower personal annual income (p = 0.025).

CONCLUSIONS

Persons with NTSCI have multimorbidity, and the MMI score was associated with increased HCU and worse health outcomes. This work emphasizes the critical need for improved healthcare and monitoring. Future work determining specific thresholds for the MMI could be helpful for triage screening to identify persons at higher risk of poor outcomes.

Dual utilization of Medicare and VA outpatient care among Veterans with spinal cord injuries and disorders

OBJECTIVE

Veterans with spinal cord injuries and disorders (SCI/D) utilizing Veterans Affairs healthcare facilities are also Medicare eligible. Use of multiple health care systems potentially duplicates or fragments care in this population; yet little is known about those using multiple systems. This study describes dual use of services paid for by VA and Medicare among Veterans with SCI/D.

DESIGN

Retrospective, cross-sectional, observational study.

PARTICIPANTS

Veterans with SCI/D (n = 13,902) who received healthcare services within the VA SCI System of Care and were eligible for or enrolled in Medicare in 2011.

INTERVENTIONS

N/A.

OUTCOME MEASURES

Patient characteristics, average number of visits and patient level frequencies of reasons for visits were determined for individuals within healthcare utilization (VA only, Medicare only, or dual VA/Medicare) groups. Multinomial logistic regression analyses were used to investigate associations of patient variables on dual use.

RESULTS

65.3% of Veterans with SCI/D were VA only users for outpatient encounters, 4.4% had encounters paid for by Medicare only, and 30.3% were dual users. Veterans were less likely to be VA only users if they were older than 69 and if they had been injured for greater than ten years. African American Veterans with SCI (compared to white) were more likely to be VA only users.

CONCLUSION

A substantial number (∼30%) of Veterans with SCI/D are dual users. These numbers highlight the importance of improved strategies to coordinate care and increase health information sharing across systems.

An Economic Analysis of the Association Among Secondary Health Conditions, Health Care Costs, and Quality of Life for Persons With Spinal Cord Injury

Background

A previous analysis using the Canadian Spinal Cord Injury (SCI) Community Survey data identified that there were individuals with a high number of secondary health conditions, high health care utilization, poor health outcomes, and unmet health care needs.

Objectives

The objectives of this study were to estimate the annual health care costs of persons with SCI who report secondary health conditions, and to determine the association between these secondary health conditions with health care utilization and self-reported life satisfaction and quality of life.

Methods

The survey respondents were divided into four groups: traumatic SCI (tSCI; those who said they received needed care and those who said they did not) and nontraumatic SCI (ntSCI; those who said they received needed care and those who said they did not). The average annual health care costs per respondent were estimated for each group. Using regression analysis, we estimated the change in average annual health care costs that were associated with an additional secondary health condition for respondents in each group.

Results

Participants who reported not receiving needed care had on average 23% more secondary health conditions than those receiving needed care. The increase in average annual health care costs associated with one additional secondary health conditions was between $428 ($37-$820) (ntSCI, receiving needed care) and $1240 ($739-$1741) (tSCI, not receiving needed care).

Conclusion

This study provides insight into potential cost savings associated with a reduction of secondary health conditions as well as an estimate of the reduction in health care costs associated with moving from not receiving all needed care to receiving needed care.

Effects and Safety of Wearable Exoskeleton for Robot-Assisted Gait Training: A Retrospective Preliminary Study

BACKGROUND

Wearable devices for robot-assisted gait training (RAGT) provide overground gait training for the rehabilitation of neurological injuries. We aimed to evaluate the effectiveness and safety of RAGT in patients with a neurologic deficit.

METHODS

Twenty-eight patients receiving more than ten sessions of overground RAGT using a joint-torque-assisting wearable exoskeletal robot were retrospectively analyzed in this study. Nineteen patients with brain injury, seven patients with spinal cord injury and two patients with peripheral nerve injury were included. Clinical outcomes, such as the Medical Research Council scale for muscle strength, Berg balance scale, functional ambulation category, trunk control tests, and Fugl-Meyer motor assessment of the lower extremities, were recorded before and after RAGT. Parameters for RAGT and adverse events were also recorded.

RESULTS

The Medical Research Council scale scores for muscle strength (36.6 to 37.8), Berg balance scale (24.9 to 32.2), and functional ambulation category (1.8 to 2.7) significantly improved after overground RAGT (p < 0.05). The familiarization process was completed within six sessions of RAGT. Only two mild adverse events were reported.

CONCLUSIONS

Overground RAGT using wearable devices can improve muscle strength, balance, and gait function. It is safe in patients with neurologic injury.

Needs and wishes for the future lower limb exoskeleton: an interview study among people with spinal cord injury with community-based exoskeleton experience

PURPOSE

Exoskeleton use by people with complete spinal cord injury (SCI) in daily life is challenging. To optimize daily exoskeleton use, a better understanding of the purpose of use and the accompanying improvements are needed. The perspective of experienced exoskeleton users could guide design improvements.

METHODS

Face-to-face semi-structured interviews were held with 13 people with SCI with exoskeleton experience. Interviews were audio-taped, transcribed, and analysed thematically.

RESULTS

Participants expressed three future purposes of exoskeleton use: for daily activities (e.g., stair climbing), exercise (e.g., staying healthy), and social interaction (e.g., standing at parties). Exoskeleton use during daily activities was the ultimate goal. Therefore, the future exoskeleton should be: easy to use, small and lightweight, tailor made, safe, comfortable, less distinctive, durable, and affordable. Improving the ease of use was relevant for all purposes, for all participants. The other suggestions for improvement varied depending on the purpose of use and the participant.

CONCLUSION

Increasingly more advanced improvements are needed to transition from an exercise purpose to social interaction, and ultimately use during daily activities. In the current study, detailed suggestions for improvements have been made. Only when multiple of these suggestions are adjusted, can the exoskeleton be used to its full potential.IMPLICATIONS FOR REHABILITATIONThe use of an exoskeleton by people with a complete spinal cord injury in daily life is still in its infancy.To optimize daily exoskeleton use, a better understanding of the purpose of use and exoskeleton improvements is needed.More advanced improvements to future exoskeletons are needed to make a transition from use as an exercise device to use during social interaction and daily activities.Improving the ease of use of future exoskeletons is considered a priority by experienced users, followed by making the exoskeleton small, lightweight, and tailor made.

Causes and length of stay of readmission among individuals with traumatic spinal cord injury: a prospective observational cohort study

BACKGROUND

Secondary conditions may reduce function and participation in individuals with chronic Spinal Cord Injury (SCI). The knowledge of reasons for readmission to the hospital may be enlightening to prevent them and remodel the health services.

STUDY DESIGN

Multicenter prospective observational study of all consecutive readmissions of persons with SCI after rehabilitation completion.

OBJECTIVES

To explore the characteristics of individuals with SCI readmitted to the hospital, the reasons for readmissions and the burden on hospitalization in terms of length of stay (LoS) for different conditions.

SETTING

31 Italian specialized SCI centers.

METHODS

Data on people with traumatic SCI readmitted to SCI centers were recorded about: age, sex, SCI level and severity group, geographical origin, readmission causes, clinical interventions during hospitalization, LoS and discharge destination. Linear and multiple logistic regression analyses were performed considering LoS (days) as dependent variable for correlations with independent variables. All tests were two-sided.

RESULTS

Among 1039 persons with traumatic SCI enrolled (mean age 46, males 85%, tetraplegia 43%), 59.09% of the readmissions were caused by urological problems, 39.74% by pressure injury and 35.41% by spasticity (68% readmitted for ≥2 causes, associated with longer LoS). The mean LoS was 48 days: pressure injury, rehabilitative needs, sexual, bowel, and pain problems were associated with longer and urological problems with shorter LoS. People from the South of the country were frequently (68%) readmitted to the northern centers.

CONCLUSIONS

Urological problems, pressure injury and spasticity were the most frequent causes of re-hospitalization in individuals with traumatic SCI. The migration trend seeking SCI-specific treatments suggests geographic areas to which health care organizations need to pay more attention.

Changes over 6 years in secondary health conditions and activity limitations in older adults aging with long-term spinal cord injury

BACKGROUND

The number of individuals aging with long-term spinal cord injury (SCI) is increasing. Still, there is limited knowledge about changes in secondary health conditions (SHCs) and activity limitations over time.

OBJECTIVES

To determine changes in SHCs and activity limitations in older adults aging with long-term SCI over 6 years, and to investigate how changes in SHCs and activity limitations are associated with gender, age, and injury characteristics.

DESIGN

Longitudinal cohort study from the Swedish Aging with Spinal Cord Injury Study (SASCIS).

SETTING

Community settings, Sweden.

PARTICIPANTS

From the initial 123 participants in the SASCIS: 78 individuals (32% women); mean age 68 years; mean time since injury 31 years; injury levels C1-L3, AIS A-D.

INTERVENTIONS

Not applicable MAIN OUTCOME MEASURE: Bowel and bladder function and problems, pain, spasticity, and the Spinal Cord Independence Measure (SCIM III).

RESULTS

Over 6 years, bowel-related problems increased (31% to 47%, p = .015) and the occurrence of constipation doubled to 24% (p = .013). There were increases in frequent urinary tract infections (10% to 26%, p = .004), use of indwelling urinary catheters (15% to 23%, p = .031), and other bladder-related problems (4% to 22%, p < .001). The occurrence of pain was high (85%), with no significant change. Spasticity increased from 41% to 62% (p < .001). Activity limitations increased (SCIM III total score mean 67 to 61, p < .001, with significant decreases in all subscales). The increase in bowel-related problems was greater in males, and the deterioration in self-care was greater in participants with longer time since injury and with traumatic injuries.

CONCLUSIONS

These findings support the notion that SHCs and activity limitations increase over time in older adults aging with long-term SCI. The results can inform clinicians and call for a proactive, holistic approach in the long-term follow-up to support healthy and active aging.

Effect of a computerized decision support system on the treatment approach of stage III or IV pressure injury in patients with spinal cord injury: a feasibility study

BACKGROUND

Stage III and IV pressure injuries (PIs) in patients with spinal cord injury (SCI) require complex interdisciplinary and interprofessional treatment approaches that are difficult to implement. Practical aspects, such as information exchange and coordination, remain challenging. We investigated whether a computerized decision support system (CDSS) could increase treatment adherence and improve clinical outcomes and interprofessional collaboration.

METHOD

In this feasibility study, a core team developed the initial treatment process and adapted it based on several discussions with clinical experts and information technologists. The CDSS followed the Basel Decubitus Approach and was used in a clinic specializing in SCI. Thirty patients with SCI admitted for stage III/IV PI between July 2016 and May 2017 were randomly allocated to standard or CDSS-supported care. Between-group differences in treatment adherence, complication rates, length of stay, and costs were analyzed using descriptive statistics. The use of the CDSS and potential barriers and facilitators were evaluated through interprofessional focus groups, transcribed verbatim, and thematically analyzed (30 participants).

RESULTS

No differences in SCI characteristics, comorbidities, or PI characteristics (localization: ischium [number (n) = 19 PI, 63%], sacrum [n = 10 PI, 33%], recurrent PI [n = 21, 70%]) were found between the two groups. Furthermore, no statistically significant differences were observed in treatment adherence, frequency of major (20% vs. 13% between CDSS and control group) and minor (33% vs 27%) complications, and length of stay (98 [±28] vs 81 [±23] days). Healthcare professionals found the CDSS to be helpful for visualizing the treatment process. However, the high workload and difficulties in the information technology processes, such as missing reminders, slow computer performance and data processing, and poor accessibility, hindered the effective implementation of the CDSS.

CONCLUSION

The implementation of the CDSS to support the treatment of stage III/IV PI in patients with SCI was feasible and included definitions of milestones, interventions, and outcomes. However, to assess the impact of the CDSS, a longer observation period is required. Further, the technical difficulties must be addressed, and solid integration of the CDSS into the clinical information system is necessary.

Effect of robot-assisted gait training on quality of life and depression in neurological impairment: A systematic review and meta-analysis

OBJECTIVE

Robot-assisted gait training (RAGT) is often used as a rehabilitation tool for neurological impairments. The purpose of this study is to investigate the effects of rehabilitation with robotic devices on quality of life and depression.

DATA SOURCES

Two electronic databases (MEDLINE and Scopus) were searched for studies from inception up to December 2022.

REVIEW METHODS

Randomized controlled trials (RCTs) and non-RCTs were pooled separately for analyses, studying each one's mental and physical health and depression. Random effect meta-analyses were run using standardized mean difference and 95% confidence interval (CI).

RESULTS

A total of 853 studies were identified from the literature search. 31 studies (17 RCTs and 14 non-RCTs) including 1151 subjects met the inclusion criteria. 31 studies were selected for the systematic review and 27 studies for the meta-analysis. The outcome measure of mental health significantly improved in favor of the RAGT group in RCTs and non-RCTs (adjusted Hedges'g 0.72, 95% CI: 0.34-1.10, adjusted Hedges g = 0.80, 95% CI 0.21-1.39, respectively). We observed a significant effect of RAGT on physical health in RCTs and non-RCTs (adjusted Hedges'g 0.58, 95% CI 0.28, 0.88, adjusted Hedges g = 0.73, 95% CI 0.12, 1.33). After realizing a sensitivity analysis in RCTs, a positive impact on depression is observed (Hedges' g of -0.66, 95% CI -1.08 to -0.24).

CONCLUSION

This study suggests that RAGT could improve the quality of life of patients with neurological impairments. A positive impact on depression is also observed in the short term. Further studies are needed to differentiate grounded and overgrounded exoskeletons as well as RCT comparing overground exoskeletons with a control group.

Arbiters of Time: The Experience of Adults Aging with Spinal Cord Injury

Time is a fundamental component of our lives. It is both objective, a structure outside of ourselves, and subjective, an element that is relative to the life we live and how we experience it. The disabled body must come to terms with time to understand the future impact of the injury and its progression, as well as how the injury will impose a new more accelerated aging process in the body, resulting in a compressed lifespan. The body also challenges time's control of the body. This paper extends the literature on the study of time to the experience of adults aging with a spinal cord injury (SCI). Drawing from interviews conducted with adults with long-term SCI, it examines how their narratives about aging and the proactive management of their lives reflect their orientation toward and anticipation of the future. Recognizing that the spoken word often carries a multiplicity of meanings, it considers what participants' words might imply about their engagement with time. The results of this study show that the process of aging is characterized by uncertainty and the expectations of functional and health decline, requiring a sense of urgency and vigilance in the face of the uncertain course of aging with SCI. Participants understood that their lifespan was compressed due to the physiological impact of accelerated aging. Knowledge of this compression made time a scarce resource. Yet, despite it being the arbiters of their futures, so too were they the arbiters of time.

Mapping of Dietary Interventions Beneficial in the Prevention of Secondary Health Conditions in Spinal Cord Injured Population: A Systematic Review

OBJECTIVES

Individuals with spinal cord injury are at risk of secondary health conditions (SHC) that develop as a consequence of autonomic dysfunction, prolonged oxidative stress and inflammation, and physical inactivity coupled with inadequate energy and nutritional intake. SHC can be debilitating and even life-threatening, and its prevention remains one of the major challenges in the continuum of medical care of aging SCI population. An unhealthy diet is a major driver of inflammation, oxidative stress, and unfavourable metabolic status and may be a practical preventive target to tackle increased SHC risk post-injury.

AIMS

To provide a catalogue of dietary interventions beneficial in prevention of SHC among individuals with SCI by conducting a systematic review of the literature on dietary interventions and dietary supplementation in promoting health and well-being after the injury. In addition, we aimed to provide a summary of observational studies exploring the association between habitual diet (macro- and micronutrients intake and dietary patterns) and health patterns following the injury.

METHOD

This review was registered at PROSPERO (University of York) with registration number CRD42022373773. Four medical databases (EMBASE.com, MEDLINE [Ovid], Cochrane CENTRAL, and Web of Science Core Collection) and Google Scholar were searched from inception until 11th July 2022. Studies were included if they were clinical trials or observational studies conducted in adult individuals with SCI and provided information of interest. Based on strength of the study design and risk of bias assessment (using the NIH tool), we classified studies from Level 1 (most reliable studies) to Level 4 (least reliable studies).

RESULTS

Of 12,313 unique citations, 47 articles (based on 43 original studies) comprising 32 interventional (22 RCTs, 3 NRCT, and 7 pre-post studies) and 11 observational studies (2 cohort studies, 2 case-control, 1 post-intervention follow-up study, and 6 cross-sectional studies) were included in the present systematic review. Twenty studies (46.5%) were classified as Level 1 or 2, indicating high/moderate methodological quality. Based on those studies, dietary strategies including high protein diet, intermittent fasting, balanced diet in combination with physical conditioning and electrical stimulation, and dietary supplementation including alpha-lipoic acid, creatine, vitamin D, and cranberry-derived supplements and probiotics were mapped as the most promising in prevention of SHC among individuals with SCI.

CONCLUSIONS

To develop timely and effective preventive strategies targeting major SHC (e.g., cardiometabolic diseases, urinary tract infections) in SCI, further research is warranted to confirm the effectiveness of dietary strategies/interventions identified through the current systematic review of the literature.

A preliminary study on the feasibility of community game-based respiratory muscle training for individuals with high cervical spinal cord injury levels: a novel approach

Background

Respiratory disorders result in rehospitalization and premature death of patients with cervical spinal cord injuries (CSCI). Community game-based respiratory muscle training (RMT) programs could reduce secondary complications.

Methods

We examined the feasibility and preliminary efficacy of RMT as a community-based exercise program. Among the 10 included participants (eight male and two female), four, one, one, and four reported C3, C4, C5, and C6 complete injuries, respectively (eight graded by American Spinal Injury Association impairment scale [ASIA] A and two by ASIA B). Their mean age was 43 ± 12.3 y. The time since injury was 10 ± 6.7 y. The participants completed an RMT program for 60 min/day, twice weekly, for 8 weeks. The participants were trained in the use of a newly developed game-based RMT device. The device provides consistent pressure for respiratory muscle strength and endurance training. Seven RMT devices were modified to allow 10 game-based RMT programs. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV₁), peak expiratory flow (PEF), vital capacity (VC), inspiratory capacity (IC), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), and peak cough flow (PCF) were measured.

Results

There were improvements after RMT compared to pre-RMT in FVC (p = 0.027, 10.62%, 0.22 effect size [ES]), PEF (p = 0.006, 23.21%, 0.45 ES), VC (p = 0.002, 35.52%, 0.60 ES), IC (p = 0.001, 46.94%, 0.81 ES), IRV (p = 0.001, 90.53%, 1.22 ES), MIP (p = 0.002, 97.25%, 1.32 ES), MEP (p = 0.005, 141.12%, 1.07 ES), and PCF (p = 0.001, 35.60%, 0.74 ES). The participants reported a positive impact of the program.

Conclusions

Community game-based RMT for individuals with CSCI appears to be safe and feasible. Community exercise with RMT use may have a positive impact on the respiratory measures for patients with CSCI who are vulnerable to respiratory compromise.

Endocrinological and inflammatory markers in individuals with spinal cord injury: A systematic review and meta-analysis

Spinal cord injury (SCI) can lead to dramatic physiological changes which can be a factor in developing secondary health conditions and might be reflected in biomarker changes in this elevated risk group. We focused specifically on the endocrine and inflammation profile differences between SCI and able-bodied individuals (ABI). Our aim was to determine the differences in inflammatory markers and endocrine profiles between SCI and ABI. We systematically searched 4 electronic databases for relevant studies. Human observational (cross-sectional, cohort, case-control) studies that compared biomarkers of interest between SCI and ABI population were included. Weighted mean difference between SCI and ABI was calculated using random-effects models. Heterogeneity was computed using I² statistic and chi-squared test. Study quality was evaluated through the Newcastle-Ottawa Scale. The search strategy yielded a total of 2,603 studies from which 256 articles were selected for full-text assessment. Sixty-two studies were included in the meta-analysis. SCI individuals had higher levels of pro-inflammatory C-reactive protein and IL-6 than ABI. Creatinine and 25-hydroxyvitamin D₃ levels were lower in SCI than ABI. Total testosterone levels and IGF-1 were also found to be lower, while cortisol and leptin levels were higher in SCI when compared to ABI. Accordingly, meta-regression, subgroup analysis, and leave-one-out analysis were performed, however, they were only able to partially explain the high levels of heterogeneity. Individuals with SCI show higher levels of inflammatory markers and present significant endocrinological changes when compared to ABI. Moreover, higher incidence of obesity, diabetes, osteoporosis, and hypogonadism in SCI individuals, together with decreased creatinine levels reflect some of the readily measurable aspects of the phenotype changes in the SCI group. These findings need to be considered in anticipating medically related complications and personalizing SCI medical care.

Effect of the Affordable Care Act on healthcare utilization for Veterans with spinal cord injuries and disorders

Context/Objective: Provisions of the Affordable Care Act (ACA) potentially increase insurance options for Veterans with disabilities. We examined Veterans with spinal cord injuries and disorders (SCI/D) to assess whether the ACA was associated with changes in healthcare utilization from Department of Veterans Affairs (VA) healthcare facilities.Design: Using national VA data, we investigated impacts on VA healthcare utilization pre- (2012/13) and post-ACA (2014/15) implementation with negative binomial regression models.Setting: VA healthcare facilities.Participants: 8,591 VA users with SCI/D. Veterans with acute myelitis, Guillain-Barré syndrome, multiple sclerosis, or amyotrophic lateral sclerosis were excluded as were patients who died during the study period.Interventions: We assessed VA healthcare utilization before and after ACA implementation.Outcome Measures: Total numbers of VA visits for SCI/D care, diagnostic care, primary care, specialty care, and mental health care, and VA admissions.Results: The number of VA admissions was 7% higher in the post than pre-ACA implementation period (P < 0.01). The number of VA visits post-implementation increased for SCI/D care (8%; P < 0.01) and specialty care (12%; P < 0.001). Conversely, the number of mental health visits was 17% lower in the post-ACA period (P < 0.001). Veterans with SCI/D who live <5 miles from their nearest VA facility received VA care more frequently than those ≥40 miles from VA (P < 0.001).Conclusion: Counter to expectations, results suggest that Veterans with SCI/D sought more frequent VA care after ACA implementation, indicating Veterans with SCI/D continue to utilize the lifelong, comprehensive care provided at VA.

Longitudinal effects of time since injury and age at injury on outcomes of people with spinal cord injury in Queensland, Australia

STUDY DESIGN

Longitudinal cohort study.

OBJECTIVES

To investigate the longitudinal effects of time since injury and age at injury on outcomes of quality of life, physical function, secondary conditions and participation, in people with traumatic spinal cord injury (SCI).

SETTING

Community resident people with spinal cord injury in Queensland, Australia.

METHODS

A baseline sample of 270 people with SCI was recruited. Telephone surveys on measures of quality of life (WHOQOL-Bref), secondary conditions (Secondary Conditions Surveillance Instrument, subset), physical functioning (Functional Independence Measure motor subscale) and participation (Community Integration Measure) were conducted each year between 2004 and 2008, and again in 2018. Random-effect within-between models were used to determine the effect of time since injury and age at injury on each outcome variable. Inverse probability-of-censoring weights were used to correct for selection bias.

RESULTS

There was an effect of time since injury on secondary conditions, with a one-year change associated with 9% higher odds of having worse Secondary Conditions Surveillance Instrument scores (odds ratio = 1.09, 95% confidence interval = 1.02, 1.17; p = 0.006). We did not find any evidence of a time since injury effect on quality of life, physical function, or participation. Similarly, we did not find any evidence of an age at injury effect on any outcome variable.

CONCLUSIONS

Secondary conditions may increase with longer time since injury among people with SCI, suggesting appropriate formal and informal supports are required to minimise the impact of these emerging health problems as individuals age.

International surveillance study in acute spinal cord injury confirms viability of multinational clinical trials

BACKGROUND

The epidemiological international landscape of traumatic spinal cord injury (SCI) has evolved over the last decades along with given inherent differences in acute care and rehabilitation across countries and jurisdictions. However, to what extent these differences may influence neurological and functional recovery as well as the integrity of international trials is unclear. The latter also relates to historical clinical data that are exploited to inform clinical trial design and as potential comparative data.

METHODS

Epidemiological and clinical data of individuals with traumatic and ischemic SCI enrolled in the European Multi-Center Study about Spinal Cord Injury (EMSCI) were analyzed. Mixed-effect models were employed to account for the longitudinal nature of the data, efficiently handle missing data, and adjust for covariates. The primary outcomes comprised demographics/injury characteristics and standard scores to quantify neurological (i.e., motor and sensory scores examined according to the International Standards for the Neurological Classification of Spinal Cord Injury) and functional recovery (walking function). We externally validated our findings leveraging data from a completed North American landmark clinical trial.

RESULTS

A total of 4601 patients with acute SCI were included. Over the course of 20 years, the ratio of male to female patients remained stable at 3:1, while the distribution of age at injury significantly shifted from unimodal (2001/02) to bimodal distribution (2019). The proportional distribution of injury severities and levels remained stable with the largest percentages of motor complete injuries. Both, the rate and pattern of neurological and functional recovery, remained unchanged throughout the surveillance period despite the increasing age at injury. The findings related to recovery profiles were confirmed by an external validation cohort (n=791). Lastly, we built an open-access and online surveillance platform ("Neurosurveillance") to interactively exploit the study results and beyond.

CONCLUSIONS

Despite some epidemiological changes and considerable advances in clinical management and rehabilitation, the neurological and functional recovery following SCI has remained stable over the last two decades. Our study, including a newly created open-access and online surveillance tool, constitutes an unparalleled resource to inform clinical practice and implementation of forthcoming clinical trials targeting neural repair and plasticity in acute spinal cord injury.

Knowledge Gaps in Biophysical Changes After Powered Robotic Exoskeleton Walking by Individuals With Spinal Cord Injury—A Scoping Review

In addition to helping individuals with spinal cord injury (SCI) regain the ability to ambulate, the rapidly evolving capabilities of robotic exoskeletons provide an array of secondary biophysical benefits which can reduce the complications resulting from prolonged immobilization. The proposed benefits of increased life-long over-ground walking capacity include improved upper body muscular fitness, improved circulatory response, improved bowel movement regularity, and reduced pain and spasticity. Beyond the positive changes related to physical and biological function, exoskeletons have been suggested to improve SCI individuals' quality of life (QOL) by allowing increased participation in day-to-day activities. Most of the currently available studies that have reported on the impact of exoskeletons on the QOL and prevention of secondary health complications on individuals with SCI, are of small scale and are heterogeneous in nature. Moreover, few meta-analyses and reviews have attempted to consolidate the dispersed data to reach more definitive conclusions of the effects of exoskeleton use. This scoping review seeks to provide an overview on the known effects of overground exoskeleton use, on the prevention of secondary health complications, changes to the QOL, and their effect on the independence of SCI individuals in the community settings. Moreover, the intent of the review is to identify gaps in the literature currently available, and to make recommendations on focus study areas and methods for future investigations.

Identifying cases of spinal cord injury or disease in a primary care electronic medical record database

OBJECTIVE

To identify cases of spinal cord injury or disease (SCI/D) in an Ontario database of primary care electronic medical records (EMR).

DESIGN

A reference standard of cases of chronic SCI/D was established via manual review of EMRs; this reference standard was used to evaluate potential case identification algorithms for use in the same database.

SETTING

Electronic Medical Records Primary Care (EMRPC) Database, Ontario, Canada.

PARTICIPANTS

A sample of 48,000 adult patients was randomly selected from 213,887 eligible patients in the EMRPC database.

INTERVENTIONS

N/A.

MAIN OUTCOME MEASURE(S)

Candidate algorithms were evaluated using sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and F-score.

RESULTS

126 cases of chronic SCI/D were identified, forming the reference standard. Of these, 57 were cases of traumatic spinal cord injury (TSCI), and 67 were cases of non-traumatic spinal cord injury (NTSCI). The optimal case identification algorithm used free-text keyword searches and a physician billing code, and had 70.6% sensitivity (61.9-78.4), 98.5% specificity (97.3-99.3), 89.9% PPV (82.2-95.0), 94.7% NPV (92.8-96.3), and an F-score of 79.1.

CONCLUSIONS

Identifying cases of chronic SCI/D from a database of primary care EMRs using free-text entries is feasible, relying on a comprehensive case definition. Identifying a cohort of patients with SCI/D will allow for future study of the epidemiology and health service utilization of these patients.

Longitudinal measurement invariance of the international spinal cord injury quality of life basic data set (SCI-QoL-BDS) during spinal cord injury/disorder inpatient rehabilitation

Purpose

This study aimed at testing the internal consistency and longitudinal measurement invariance of a brief quality of life questionnaire—the spinal cord injury quality of life basic data set (SCI-QoL-BDS)—among individuals with spinal cord injury/disorder undergoing first inpatient rehabilitation.

Methods

Longitudinal data from the Swiss spinal cord injury inception cohort study were used. Participants (n = 218) completed the SCI-QoL-BDS at one and three months post injury and at discharge. The SCI-QoL-BDS consists of three items assessing satisfaction with life as a whole, physical health, and psychological health. Internal consistency was examined at each time point and longitudinal measurement invariance was tested using longitudinal confirmatory factor analysis.

Results

Internal consistency coefficients ranged between .82 and .90. The confirmatory factor analysis revealed invariance of the factor structure and of all factor loadings across time. Additionally, all item intercepts except the one of satisfaction with physical health were invariant across time, suggesting partial intercept invariance of the SCI-QoL-BDS. Indeed, a response shift was observed in satisfaction with physical health. This item was evaluated more negatively in the early phase of inpatient rehabilitation, indicating the change of the evolving physical situation after the onset of a spinal cord injury.

Conclusion

The SCI-QoL-BDS is a consistent and valid measure to assess quality of life among individuals undergoing first spinal cord injury/disorder inpatient rehabilitation. However, we recommend using latent variable frameworks instead of mean scores when examining longitudinal changes in the measure to account for potential response shift.

Developing a consensus on the core educational content to be acquired by people with spinal cord injuries during rehabilitation: findings from a Delphi study followed by a Consensus Conference

STUDY DESIGN

Three-round Delphi study followed by a Consensus Conference with selected stakeholders.

OBJECTIVES

To identify a set of core educational content that people with spinal cord injury (SCI) need to acquire during rehabilitation.

SETTING

The Delphi study was performed electronically. The Consensus Conference was held at the Città della Salute e della Scienza University Hospital of Turin, Italy.

METHODS

A panel of 20 experts (healthcare professionals and SCI survivors) participated in a three-round Delphi study. In round 1, arguments for core educational content were solicited and reduced into items. In rounds 2 and 3, a five-point Likert scale was used to find consensus on and validate core educational content items (threshold for consensus and agreement: 60% and 80%, respectively). A Consensus Conference involving 32 stakeholders was held to discuss, modify (if appropriate) and approve the list of validated items.

RESULTS

The 171 arguments proposed in round 1 were reduced into 74 items; 67 were validated in round 3. The Consensus Conference approved a final list of 72 core educational content items, covering 16 categories, which were made into a checklist.

CONCLUSIONS

Consensus was achieved for a set of core educational content for people with SCI. The resultant checklist could serve as an assessment tool for both healthcare professionals and SCI survivors. It can also be used to support SCI survivors' education, streamline resource use and bridge the gap between information provided during rehabilitation and information SCI survivors need to function in the community.

Shorter telomeres among individuals with physical disability: The moderating role of perceived stress

OBJECTIVES

Evidence suggests that individuals with physical disability may suffer from psychological distress and accelerated cellular aging, manifested by shortened telomere length (TL), compared with healthy individuals. Studies indicate that high levels of perceived stress and depression may increase the physiological susceptibility and thus, may contribute to a short TL. However, the moderating role of perceived stress and depression within the relationship between physical disability and TL remains unknown.

METHODS

The participants consisted of 119 male subjects (mean age 54.36 years, range 35-70). Of them, 30 were able-bodied and 86 had a physical disability: 34 were due to Poliomyelitis (polio) and 55 were due to spinal cord injury (SCI). Blood samples for TL analysis were collected; the participants completed questionnaires and underwent disability evaluation.

RESULTS

Participants with disability had a shorter TL as well as elevated levels of perceived stress and depression compared with able-bodied controls. Both the perceived stress and depression were correlated with a shorter TL. Nonetheless, perceived stress, rather than depression, moderated the relationship between disability and TL; among participants with higher perceived stress levels, in particular, individuals with physical disability had a shorter TL than the able-bodied controls.

DISCUSSION

The present findings suggest that individuals with physical disability and who exhibit high levels of perceived stress may be particularly vulnerable for accelerated cellular aging, suggesting that perceived stress can be used as a valuable target for intervention.

Life Satisfaction in Individuals With Long-Term Traumatic Spinal Cord Injury: An Investigation of Associated Biopsychosocial Factors

OBJECTIVE

To investigate relationships between self-reported biological, psychological, and social factors and global, vocational, and home life satisfaction in individuals with traumatic spinal cord injury (SCI) an average of more than 30 years postinjury.

DESIGN

Cross-sectional analyses of self-report assessment data.

SETTING

Specialty and university hospitals in the southeastern and midwestern United States.

PARTICIPANTS

Individuals with a history of traumatic SCI (n=546) who responded to the most recent data collection period of the SCI Longitudinal Aging Study (2018-2019) and who were at least 2 years postinjury and at least 18 years or older at initial study enrollment.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Global life satisfaction, home life satisfaction, and vocational life satisfaction as measured by the Life Situation Questionnaire-Revised.

RESULTS

Taken together, the biopsychosocial variables explained 55.1% of the variance in global life satisfaction. Less severe depressive symptoms, greater emotional social support, and greater instrumental social support were significantly associated with greater global life satisfaction. Together, the independent variables explained 50.7% of the variance in home life satisfaction. Being in a relationship, having less severe depressive symptoms, having greater emotional social support, and having greater instrumental social support were significantly associated with home life satisfaction. Together, the independent variables explained 44.8% of the variance in vocational satisfaction. Being White, non-Hispanic, having more years of education, being in a relationship, having less severe depressive symptoms, and having greater emotional social support were significantly associated with greater vocational satisfaction.

CONCLUSION

These results support the need to assess psychological symptoms and available social support as potential modifiable factors related to several domains of life satisfaction in this aging population. Improving psychological symptoms and strengthening available social support may relate to improved life satisfaction.

Interdisciplinary follow-up clinic for people with spinal cord injury: a retrospective study of a carousel model

STUDY DESIGN

Explorative retrospective cohort study.

OBJECTIVE

Secondary health conditions (SHCs) are common in people with spinal cord injury (SCI). To date, little is known about the effectiveness of long-term follow-up care in preventing SHCs. The objective of this study was to explore the therapeutic content of an interdisciplinary follow-up clinic by retrospective analyses of provided recommendations and collected data concerning SHCs.

SETTING

Rehabilitation center Sint Maartenskliniek, The Netherlands.

METHODS

All people with SCI, who visited one or more outpatient interdisciplinary follow-up clinics between January 2012 and October 2020 were included in this study. Treatment information was retrieved from their medical records.

RESULTS

The 264 participants of the follow-up clinic received, after their first visit, an average of 3.9 recommendations regarding SHCs. Most recommendations were preventive in nature (43%), and were related to physical SHCs (61%). Most recommendations were followed by the participants (34% out of 40% that could be determined) and half of the underlying problems were solved (31% out of 62%). The bodyweight and respiratory function remained stable over time.

CONCLUSION

Participants of the interdisciplinary follow-up clinics received extensive recommendations on a variety of subjects, which most likely, reflects the interdisciplinary approach. Recommendations were followed-up to a large extent, resulting in solving half of the underlying SHCs. This way, worse SHCs were prevented by the recommendations. This findings, together with the stability of respiratory function and bodyweight, suggests the added value of the interdisciplinary follow-up clinic to usual care. More prospective research is necessary to investigate the (cost-)effectiveness.

Community exercise for individuals with spinal cord injury with inspiratory muscle training: A pilot study

Context/Objective: Respiratory disorders are a common cause of rehospitalization, and premature death in individuals with spinal cord injuries (SCI). Respiratory training combined with community exercise programs may be a method to reduce secondary complications in this population.Objective: The present study explores the inclusion of inspiratory muscle training (IMT) in an existing community exercise program.Design: Case series.Setting: Community.Participants: Participants (N = 6) completed the exercise program. Five were male and one was female; four reported incomplete injuries, and two reported complete injuries; four had cervical injuries, and two had thoracic injuries. The average age was 33 years (SD = 18.6) and time since injury was 7 years (SD = 4.0).Interventions: Participants completed an 8-week program, once-per-week for 4 h that included a circuit of resistance training, aerobic exercise, trunk stability, and education. IMT was completed as a home exercise program.Outcome Measures: Transfer test, T-shirt test, four-directional reach, four-directional trunk strength, weekly training diaries, and a subjective interview.Results: Twenty-eight training logs were collected. All measures improved: transfer test (mean = -14.62, SD = 7.00 s), T-shirt test (mean = -7.83, SD = 13.88 s), four-directional reach (mean = 3.75, SD = 8.06 in) and hand-held dynamometer (mean = 6.73, SD = 8.02 kg). Individuals reported a positive impact of the program.Conclusions: This pilot study demonstrated community exercise with IMT use may have positive impact on functional measures for people with SCI who are vulnerable to respiratory compromise. Continued education may increase successful health outcomes.Trial Registration: NCT03743077.

Unmet health care needs and inequality: A cross-country comparison of the situation of people with spinal cord injury

Objective

To estimate and compare unmet health care needs of persons with spinal cord injury (SCI) across countries, the causes of these shortfalls, and the role of income.

Data Sources

We analyzed cross‐sectional data of 20 countries from the International Spinal Cord Injury (InSCI) survey, a compendium of comparable data on the living situation of persons with SCI. Data included information on high‐, middle‐, and low‐income countries. The survey comprises information on 12,095 participants.

Study Design

We used logit regressions to estimate the probability of unmet health care needs of persons with SCI and its causes. We adjusted the results by the individuals' characteristics and countries' fixed effects. We disaggregated the results by income decile of individuals in each country.

Data Collection/Extraction Methods

The inclusion criteria for the InSCI survey were adults aged 18 years and older with SCI living in the community, who were able to respond to the survey and who provided informed consent.

Principal Findings

Unmet health care needs are significant for people with long‐term conditions like SCI, where people in low‐income groups tend to be more affected. Among the barriers to meeting health care needs, the foremost is health care cost (in 11 of the 20 countries), followed by transportation and service availability. Persons with SCI in Morocco reported the highest probability of unmet health care needs in the sample, 0.54 (CI: 047–0.59), followed well behind by South Africa, 0.27 (CI: 0.20–0.33), and Brazil, 0.26 (CI: 0.20–0.33). In contrast, persons with SCI in Spain, 0.06 (CI: 0.04–0.08), reported the lowest probability of unmet health care needs, closely followed by Norway, 0.07 (CI: 0.05–0.09), Thailand, 0.08 (CI: 0.05–0.11), France, 0.08 (CI: 0.06–0.11), and Switzerland, 0.09 (CI: 0.07–0.10).

Conclusions

SCI is a long‐term, irreversible health condition characterized by physical impairment and a series of chronic illness. This makes SCI a high‐need, high‐cost group that faces significant unmet health care needs, which are mainly explained by the costs of health services, transportation, and services availability. This situation is prevalent in low‐, middle‐, and high‐income countries, where persons in lower income groups are disproportionately affected. To improve the situation, a combination of measures from the health and social systems are required.

Cardiorespiratory Responses to 10 Weeks of Exoskeleton-Assisted Overground Walking Training in Chronic Nonambulatory Patients with Spinal Cord Injury

Exercise intensity of exoskeleton-assisted walking in patients with spinal cord injury (SCI) has been reported as moderate. However, the cardiorespiratory responses to long-term exoskeleton-assisted walking have not been sufficiently investigated. We investigated the cardiorespiratory responses to 10 weeks of exoskeleton-assisted walking training in patients with SCI. Chronic nonambulatory patients with SCI were recruited from an outpatient clinic. Walking training with an exoskeleton was conducted three times per week for 10 weeks. Oxygen consumption and heart rate (HR) were measured during a 6-min walking test at pre-, mid-, and post-training. Exercise intensity was determined according to the metabolic equivalent of tasks (METs) for SCI and HR relative to the HR reserve (%HRR). Walking efficiency was calculated as oxygen consumption divided by walking speed. The exercise intensity according to the METs (both peak and average) corresponded to moderate physical activity and did not change after training. The %HRR demonstrated a moderate (peak %HRR) and light (average %HRR) exercise intensity level, and the average %HRR significantly decreased at post-training compared with mid-training (31.6 ± 8.9% to 24.3 ± 7.3%, p = 0.013). Walking efficiency progressively improved after training. Walking with an exoskeleton for 10 weeks may affect the cardiorespiratory system in chronic patients with SCI.

The importance of meaningful participation: health benefits of volunteerism for older adults with mobility-limiting disabilities

Volunteerism has been increasingly recognised as a health promotion activity for older adults. However, volunteerism has largely been the domain of those who are in good health with few to no physical limitations, and there is limited information about the experiences of older adults with disabilities. This study explores why older adults with mobility-limiting disabilities engage in volunteer work and their perceptions of the personal benefits of volunteering. Twenty older adults, from three Midwest towns in the United States of America, participated in semi-structured, in-depth, face-to-face interviews. Participants in this study identified as having serious difficulty walking or climbing stairs due to a health condition and had volunteered in the last year. Participants were selected purposively for maximum variation in terms of type of disability/impairment, race, gender and age. The constant comparative method of analysis was used to identify themes from their discussions. When asked about why they volunteer and the personal benefits of volunteering, participants discussed seeking out activities that were meaningful to them for both altruistic and more self-directed reasons. They identified a number of physical and emotional health benefits that they saw as directly and indirectly related to being able to participate in these meaningful activities. Findings from this study suggest that, for older adults with disabilities who are interested in volunteer activities, volunteerism can be a beneficial health promotion activity and a potential mechanism for increasing opportunities for meaningful inclusion and participation in their communities.

Functional electrical stimulation cycling exercise after spinal cord injury: a systematic review of health and fitness-related outcomes

OBJECTIVES

The objective of this review was to summarize and appraise evidence on functional electrical stimulation (FES) cycling exercise after spinal cord injury (SCI), in order to inform the development of evidence-based clinical practice guidelines.

METHODS

PubMed, the Cochrane Central Register of Controlled Trials, EMBASE, SPORTDiscus, and CINAHL were searched up to April 2021 to identify FES cycling exercise intervention studies including adults with SCI. In order to capture the widest array of evidence available, any outcome measure employed in such studies was considered eligible. Two independent reviewers conducted study eligibility screening, data extraction, and quality appraisal using Cochranes' Risk of Bias or Downs and Black tools. Each study was designated as a Level 1, 2, 3 or 4 study, dependent on study design and quality appraisal scores. The certainty of the evidence for each outcome was assessed using GRADE ratings ('High', 'Moderate', 'Low', or 'Very low').

RESULTS

Ninety-two studies met the eligibility criteria, comprising 999 adults with SCI representing all age, sex, time since injury, lesion level and lesion completeness strata. For muscle health (e.g., muscle mass, fiber type composition), significant improvements were found in 3 out of 4 Level 1-2 studies, and 27 out of 32 Level 3-4 studies (GRADE rating: 'High'). Although lacking Level 1-2 studies, significant improvements were also found in nearly all of 35 Level 3-4 studies on power output and aerobic fitness (e.g., peak power and oxygen uptake during an FES cycling test) (GRADE ratings: 'Low').

CONCLUSION

Current evidence indicates that FES cycling exercise improves lower-body muscle health of adults with SCI, and may increase power output and aerobic fitness. The evidence summarized and appraised in this review can inform the development of the first international, evidence-based clinical practice guidelines for the use of FES cycling exercise in clinical and community settings of adults with SCI. Registration review protocol: CRD42018108940 (PROSPERO).

[Quality of life in patients with spinal cord injury for at least 10years: Importance of secondary health complications]

OBJECTIVE

To determine the quality of life of spinal cord injuries with more than 10 years of evolution. Assess the prevalence of secondary complications, and their relationship with quality of life and time since the injury.

PATIENTS AND METHOD DESIGN

Cross-sectional epidemiological study.

STUDY SUBJECTS

Patients with traumatic spinal cord injury, more than 10 years after the injury, and who met the inclusion criteria.

METHOD

Quality of life was assessed using the International spinal cord injury quality of life basic data set. Variables included: individual factors, neurological deficit, level of injury and secondary complications.

RESULTS

131 subjects were included in the study with a mean age of 49 years, and a time since the injury of 21 years (11-53 years). The mean number of secondary complications was 2, the most frequent being urological, in 76 subjects (58%). There were no significant differences between the number of complications and the time elapsed since the spinal cord injury. The quality of life was significantly lower in those with a higher number of complications (P=.003). Urological complications (P=.04, 95% CI: -1.02 to 2), musculoskeletal pain (P=.01, 95% CI: 1-6), respiratory complications (P=.05, 95% CI: -3 to 0.1) and neuropathic pain that interfered with basic life activities (P=.01, 95% CI: 1-5) were significantly related to a lower quality of life.

CONCLUSIONS

Secondary complications are common after spinal cord injury, although their number does not increase over time after injury. Quality of life is conditioned by the existence of different complications such as the existence of musculoskeletal pain.

Mediating Effects of Pain Interference on the Relationships Between Pain Intensity and Probable Major Depression Among Participants With Spinal Cord Injury

OBJECTIVE

To evaluate whether pain interference mediates the relationship between pain intensity and probable major depression (PMD) among persons with spinal cord injury (SCI), accounting for differences in the frequency of prescription medication use and resilience.

DESIGN

Cross-sectional analysis using self-report assessment.

SETTING

Medical university in the Southeastern United States.

PARTICIPANTS

There were a total of 4670 participants (N=4670), all of whom had traumatic SCI of at least 1-year duration, identified from the Southeastern Regional SCI Model System and 2 state-based surveillance systems.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The Patient Health Questionnaire-9 was used to define PMD. Covariates included demographic and injury characteristics, pain severity, pain interference, and resilience. Separate sets of multistage logistic regression analyses were conducted for 3 levels of prescription pain medication use (daily, occasional/weekly, none).

RESULTS

Pain intensity was related to a greater risk of PMD (odds ratio [OR]_{daily pain medication user}, 1.28; 95% confidence interval [CI], 1.21-1.35; OR_{occasional/weekly pain medication user}, 1.26; 95% CI, 1.16-1.36; OR_{nonpain medication user}, 1.44; 95% CI, 1.33-1.56), but this relationship disappeared after consideration of pain interference (OR_{daily pain medication user}, 0.97; 95% CI, 0.90-1.04; OR_{occasional/weekly pain medication user}, 0.94; 95% CI, 0.84-1.05; OR_{nonpain medication user}, 1.07; 95% CI, 0.95-1.20), which indicates pain interference was a mediator between pain intensity and PMD and there was no direct relationship between pain intensity and PMD. Resilience was protective of PMD in each model but was not a mediator.

CONCLUSIONS

Although pain intensity was associated with PMD, the relationship was mediated by pain interference. Resilience was an important protective factor. Therefore, clinicians should assess pain interference when screening for PMD and direct treatment at reducing pain interference. Building resilience may further reduce the risk of PMD.

Experiences of secondary health conditions amongst people with spinal cord injury in South Africa: A qualitative study

Background

Secondary health conditions (SHCs) such as pain, pressure sores, sexual problems, bowel and bladder problems are prevalent throughout the lifespan of people with spinal cord injury (SCI). Studies have reported that SHCs decrease life expectancy and increase health care costs. Studies on the lived experience of SHCs are, however, limited.

Objectives

To explore the experiences of SHCs amongst people with SCI in a public rehabilitation hospital in South Africa.

Method

Face-to-face semi-structured interviews were conducted with people with SCI from August 2018 to July 2019. All interviews were transcribed verbatim and analysed using a content analysis approach.

Results

Seventeen people with SCI were interviewed. Participants experienced a range of SHCs. The most common experienced SHC was pain (94%). The main theme that emerged from the analysis was 'the impact of secondary health conditions on health and well-being'. The categories linked to the impact were SHCs co-occurrence and how SHCs limit function, restrict participation, affect mental health and disrupt lives.

Conclusion

We found that SHCs were enormously impactful on our participants' lives and health, as illustrated by their stories of fear, embarrassment and shame. Understanding people with SCI experiences of SHCs can enhance communication between people with SCI and health professionals and may help develop prevention strategies.

Clinical implications

To enhance patient-centred care, health professionals are encouraged to actively listen to patients' experiences of illness and the impact on health and wellbeing.

Association of Secondary Health Conditions With Future Chronic Health Conditions Among Persons With Traumatic Spinal Cord Injury

Background

Secondary health conditions (SHC) are physical and mental health conditions that are causally related to disabilities. Studies have found that SHC increase risk of negative health outcomes among people with traumatic spinal cord injury (TSCI). However, little has been done to assess the association of SHC with the risk of chronic health conditions (CHC) after TSCI.

Objectives

To identify the prevalence of CHC in adults with TSCI, changes in CHC at follow-up, and the associations of baseline SHC with future CHC.

Methods

Participants included 501 adults with TSCI of at least 1-year duration, identified through a population-based surveillance system. Baseline and follow-up self-report assessments were completed. We measured seven SHC: fatigue, spasticity, pain, pressure ulcers, subsequent injury, fracture, and anxiety disorder, and measured seven CHC: diabetes, heart attack, coronary artery disease, stroke, cancer, hypertension, and high blood cholesterol. Control variables included gender, race/ethnicity, age at injury, years post injury, injury severity, smoking status, binge drinking, and taking prescription medication. We implemented a Poisson regression model for the multivariate analyses.

Results

The total number of CHC, the percentage of participants having at least one CHC, and prevalence of three individual CHC (diabetes, cancer, and high cholesterol) increased from baseline to follow-up. After controlling for demographic, injury characteristics, and behavioral factors, pain interference and anxiety disorder at baseline were associated with the total number of CHC at follow-up.

Conclusion

CHC are common among adults with TSCI and increase significantly over time. Pain and anxiety disorders appear to be risk factors for future CHC.

Systematic review on wearable lower-limb exoskeletons for gait training in neuromuscular impairments

Gait disorders can reduce the quality of life for people with neuromuscular impairments. Therefore, walking recovery is one of the main priorities for counteracting sedentary lifestyle, reducing secondary health conditions and restoring legged mobility. At present, wearable powered lower-limb exoskeletons are emerging as a revolutionary technology for robotic gait rehabilitation. This systematic review provides a comprehensive overview on wearable lower-limb exoskeletons for people with neuromuscular impairments, addressing the following three questions: (1) what is the current technological status of wearable lower-limb exoskeletons for gait rehabilitation?, (2) what is the methodology used in the clinical validations of wearable lower-limb exoskeletons?, and (3) what are the benefits and current evidence on clinical efficacy of wearable lower-limb exoskeletons? We analyzed 87 clinical studies focusing on both device technology (e.g., actuators, sensors, structure) and clinical aspects (e.g., training protocol, outcome measures, patient impairments), and make available the database with all the compiled information. The results of the literature survey reveal that wearable exoskeletons have potential for a number of applications including early rehabilitation, promoting physical exercise, and carrying out daily living activities both at home and the community. Likewise, wearable exoskeletons may improve mobility and independence in non-ambulatory people, and may reduce secondary health conditions related to sedentariness, with all the advantages that this entails. However, the use of this technology is still limited by heavy and bulky devices, which require supervision and the use of walking aids. In addition, evidence supporting their benefits is still limited to short-intervention trials with few participants and diversity among their clinical protocols. Wearable lower-limb exoskeletons for gait rehabilitation are still in their early stages of development and randomized control trials are needed to demonstrate their clinical efficacy.

Twenty-Five-Year Cross-sequential Analysis of Self-reported Problems: Findings From 5 Cohorts From the Spinal Cord Injury Longitudinal Aging Study

OBJECTIVE

To evaluate how self-reported problems change over time among people with spinal cord injury (SCI).

DESIGN

Cross-sequential analysis.

SETTING

Medical university in the Southeastern United States.

PARTICIPANTS

Participants included 1997 individuals with traumatic SCI of at least 1-year duration who were identified from participation in the SCI Longitudinal Aging Study from 1993-2018.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

The outcomes analyzed were 6 problem factors defined as health, social isolation, emotional distress, environmental barriers, money, and lack of opportunities. A series of cross-sequential models, using PROC MIXED procedure, were developed to evaluate the initial and change of the 6 problem factors over the 6 times of measurements in 25 years.

RESULTS

Years post injury was negatively associated with initial status of problems of social isolation, emotional distress, environmental barriers, and lack of opportunities because participants with more years post injury at baseline reported lower scores on each factor. Longitudinally, with increased years post injury, higher scores were observed on the health problem factor. However, problems of social isolation, emotional distress, environmental barriers, money, and lack of opportunities decreased over time with increasing years post injury.

CONCLUSIONS

Participants had more health problems with increasing years after SCI, but fewer problems of social isolation, emotional distress, environmental barriers, money, and lack of opportunities.
