Is the Level of Consent to a National Research Registry Associated With Patient Outcomes After Traumatic Spinal Cord Injury? A Population-Based Study From the Rick Hansen Spinal Cord Injury Registry

OBJECTIVE

We examined the impact of consenting to the Rick Hansen Spinal Cord Injury Registry on outcomes: acute length of stay, in-hospital mortality, medical complications (pressure injuries and pneumonia), and the final discharge destination following a spinal cord injury using the national Rick Hansen Spinal Cord Injury Registry dataset.

DESIGN

A retrospective cohort study was conducted using Rick Hansen Spinal Cord Injury Registry participant data from 2014 to 2019. Participants approached for enrollment were grouped into 1) PC: provided full consent including community follow-up interviews, 2) DWC: declined community follow-up interviews but accepted minimal data collection that may include initial/final interviews and/or those who later withdrew consent, and 3) DC: declined consent to any participation. As no data was collected for the DC group, descriptive, bivariate, and multivariable regression analysis was limited to the PC and DWC groups.

RESULTS

Of 2811 participants, 2101 (74.7%) were PC, 553 (19.7%) were DWC, and 157 (5.6%) were DC. DWC participants had significantly longer acute length of stay, more acute pneumonias/pressure injuries, and were less likely to be discharged home than PC participants. All these associations-except pneumonia-remained significant in the multivariable analyses.

CONCLUSIONS

Not participating fully in Rick Hansen Spinal Cord Injury Registry was associated with more complications and longer hospital stays.

Efficacy of Blood Flow Restriction Exercise for Improving Lower Limb Muscle Strength and Function in Chronic Spinal Cord Injury: A Randomized Controlled Trial

The objective of the present study was to evaluate the efficacy of low-load (LL) blood flow restriction exercise (BFRE) for improving lower limb muscle strength, muscle thickness and physical function in individuals with spinal cord injury (SCI). In a randomized sham-controlled trial, 21 participants (age ≥ 18 years, SCI duration ≥ 1 year, knee extensor strength grade 2-4, ASIA A-D) were randomized to either 45-min LL-BFRE (n = 11) or sham BFRE (n = 10) twice/week for 8 weeks. The exercise protocol consisted of four sets (30 × 15 × 15 × 15 repetitions) of unilateral seated leg extensions and leg curls at 30%-40% of 1RM performed with pneumatic cuffs applied proximally on the trained limb and inflated to 40% of total arterial occlusion pressure (BFRE) or non-inflated (sham exercise). Maximal voluntary isometric quadriceps and hamstring muscle strength, quadriceps muscle thickness, thigh circumference, and physical function were assessed at baseline, after 4 and 8 weeks of training and at 4-week follow-up. No significant between-group differences were found between BFRE and sham exercise in quadriceps or hamstring muscle strength, 10-m walking test, timed up & go, 6-min walking test or the spinal cord independence measure. In contrast, a significant between-group difference favoring BFRE was present for muscle thickness and thigh circumference from baseline to 4-week follow-up (0.76 cm (95% CI: 0.32; 1.20, p = 0.002) and 2.42 cm (0.05; 4.79, p = 0.05), respectively). In conclusion, there was no significant difference in the effect of LL-BFRE and sham exercise on muscle strength and physical function in individuals with SCI. However, significant increases in muscle thickness and thigh circumference were observed in favor of BFRE. Trial Registration: ClinicalTrials.gov identifier: NCT03690700.

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

OBJECTIVE

To systematically review the health-related quality of life (HRQoL) burden and costs of spinal cord injury (SCI) on health services, patients and wider society.

METHODS

A systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement was conducted in March 2021 through Scopus, PubMed and Embase databases. Inclusion criteria were quantitative studies on SCI reporting healthcare costs, social costs and/or HRQoL measured with the Euroqol EQ-5D or Short-Form 36. Risk of bias was assessed using the QualSyst tool. Descriptive analyses, random-effects direct meta-analysis and random-effects meta-regression were conducted.

RESULTS

A total of 67 studies were eligible for inclusion. SCI individuals tend to report higher HRQoL in mental than physical dimensions of the Short-Form 36. Neurological level of SCI negatively affects HRQoL. Cross-sectional studies find employment is associated with better HRQoL, but the effect is not observed in longitudinal studies. The estimated lifetime expenditure per individual with SCI ranged from US$0.7 million to US$2.5 million, with greater costs associated with earlier age at injury, neurological level, United States of America healthcare setting and the inclusion of non-healthcare items in the study.

CONCLUSIONS

SCI is associated with low HRQoL on mobility and physical dimensions. Mental health scores tend to be greater than physical scores, and most dimensions of HRQoL appear to improve over time, at least over the first year. SCI is associated with high costs which vary by country.

Wheelchair Repairs: Delays, Causes, and Associated Outcomes

OBJECTIVE

To examine the length of time to complete wheelchair repairs and the relationship between negative outcomes and the factors that prevented or determined who performed the repairs.

DESIGN

Survey, cross-sectional.

SETTING

Nine spinal cord injury (SCI) Model Systems Centers.

PARTICIPANTS

Wheelchair users with SCI reporting at least 1 repair (N=301).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Prevalence of adverse consequences associated with wheelchair repairs, repairs completed of those needed, and time elapsed before wheelchair repair.

RESULTS

Of the participants, 76% reported all necessary repairs were completed, 7% indicated that some repairs were addressed, and 14% reported none of the repairs were completed. The most common reason for incomplete repairs (30%) was the vendor's failure to complete the repair after being contacted. Among the repairs that were successfully completed, 56% were performed by vendors. The median time elapsed before repair was 14 days, with no significant difference observed in the time taken for repairs across different components. The most common consequences were being forced to use a backup wheelchair or being confined at home. A greater percentage of participants experienced each type of consequence, except injury, for repairs completed by vendors.

CONCLUSIONS

The high percentage of uncompleted wheelchair repairs poses a significant risk to users, and this risk is compounded by prolonged time taken by vendors to address breakdowns. Unsatisfactory vendor service was common, with a significantly larger proportion of participants experiencing consequences for repairs that required a vendor. This seems to indicate structural inadequacies within the repair process and the need for interventions to address these issues.

Handrim kinetics and quantitative ultrasound parameters for assessment of subacromial impingement in wheelchair users with pediatric-onset spinal cord injury

BACKGROUND

Most manual wheelchair users with pediatric-onset spinal cord injury (SCI) will experience shoulder pain or pathology at some point in their life. However, guidelines for preservation of the upper limb in children with SCI are limited.

RESEARCH QUESTION

What are the relationships between manual wheelchair handrim kinetics and quantitative ultrasound parameters related to subacromial impingement in individuals with pediatric-onset SCI?

METHODS

Subacromial impingement risk factors including supraspinatus tendon thickness (SST), acromiohumeral distance (AHD), and occupation ratio (OR; SST/AHD) were measured with ultrasound in 11 manual wheelchair users with pediatric-onset SCI. Handrim kinetics were acquired during the stroke cycle, including peak resultant force (FR), peak rate of rise of resultant force (ROR) and fractional effective force (FEF). Variability of handrim kinetics was computed using the coefficient of variation and linear regression was performed to assess correlations between handrim metrics and quantitative ultrasound parameters.

RESULTS

Peak resultant force significantly increased 1.4 % and variability of FEF significantly decreased 8.0 % for every 0.1 cm increase in AHD. FEF decreased 3.5 % for every 0.1 cm increase in SST. Variability of peak resultant force significantly increased 3.6 % and variability of peak ROR of resultant force significantly increased 7.3 % for every 0.1 cm increase in SST. FEF variability significantly decreased 11.6 % for every 0.1 cm increase in SST. Peak ROR significantly decreased 1.54 % with every 10 % increase in OR. FEF variability significantly decreased 1.5 % with every 10 % increase in OR.

SIGNIFICANCE

This is the first study to investigate relationships among handrim kinetics and shoulder structure in manual wheelchair users with pediatric-onset SCI. Associations were identified between subacromial impingement risk factors and magnitude and variability of wheelchair handrim kinetics. These results indicate the critical need to further explore the relationships among wheelchair handrim kinetics, shoulder joint dynamics, and shoulder pathology in manual wheelchair users with pediatric-onset SCI.

Predictive factors and quality of life assessment among patients with spinal cord injury in the Middle East: a systematic review

PURPOSE

Spinal cord injury (SCI) is impairment of the spinal cord that adversely affects patients' health and quality of life (QoL). The aim of the study was to assess the quality of life (QoL) and related factors in patients with traumatic spinal cord injury in Middle Eastern countries.

METHODS

PubMed, Ovid Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), EBSCOhost, psycINFO, and Google Scholar were systematically searched for eligible studies published in peer-reviewed journals up till October 2023.

RESULTS

Out of 1060 papers found in the literature, only 18 studies from Iran, Lebanon, and Turkey met the inclusion criteria. The majority of the studies employed the SF-36 scale to assess for QoL. In general, all SCI patients had reduced QoL scores when compared to the healthy population. Some of the factors such as age, education level, the level of injury, time since injury onset, marriage, and job opportunities were correlated with SCI subjects QoL. Our papers were assessed and found to be of both good and high quality.

CONCLUSION

This review emphasizes the significant shortage of QoL studies among SCI patients in the Middle East countries and highlights the importance of improving the QoL of this marginalized population. This work should enhance the governments to establish rehabilitation centers, social and economic support systems, and mental health services to diminish complications arising from SCI.

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.

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

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

Work-related disability is common in persons with spinal cord injury (SCI). The aims of this study are to examine the associations of employment with self-perceived health (SPH) and quality of life (QoL) across 22 countries and to explore the covariates around employment and SPH and QoL.

SETTING

Community.

METHODS

We analyzed 9494 community-dwelling persons with SCI aged 18-65. We performed an adjusted regression and path analysis. The independent variable was 'employment' and the dependent variables were two single items: QoL (very poor to very good) and SPH (excellent to poor). Covariates included the Gross Domestic Product (GDP), education, time since SCI, age, gender, years of employment after SCI, SCI level (paraplegia, tetraplegia), and completeness of SCI.

RESULTS

Participants' mean age was 47, 74% were male, and 63% had paraplegia. We found an association between employment and QoL and SPH. While the magnitude of the effect of employment on QoL did not differ across GDP quartiles, its perceived effect on QoL was found to be significant in the highest GDP quartile. Employment was predictive of good SPH in two GDP quartiles (Q1 and Q4), but significant across all quartiles when predicting poor perceptions, with the magnitude of effect varying significantly.

CONCLUSIONS

Employment is closely related to QoL and SPH depending on the GDP. We may positively influence the QoL and SPH in the SCI population to promote better employment outcomes by considering the infrastructure and economy.

Pain and quality of life in persons with spinal cord injury: Mediating effects of mindfulness, self-efficacy, social support, and functional independence

OBJECTIVE

To identify mediating roles of mindfulness, self-efficacy, social support, and functional independence in the relationship between pain and quality of life (QOL) in persons with spinal cord injury (SCI).

METHODS

A cross-sectional descriptive study was conducted using a sample of 272 persons with SCI living in the United States. The participants completed self-report standardized questionnaires on a Qualtrics survey. A parallel mediation analysis adjusting for covariates was performed to test the hypotheses.

RESULTS

Findings showed significant direct effects of pain on functional independence, self-efficacy, mindfulness, and social support. Self-efficacy, mindfulness, and social support had significant direct effects on QOL. In the mediation analysis, mindfulness, self-efficacy, and social support significantly mediated the relationship between pain and QOL, controlling for other variables in the model.

CONCLUSIONS

This study adds to the extant literature by providing evidence that mindfulness, self-efficacy, and social support not only directly contribute to QOL but are likely to mitigate the negative effect of pain on QOL in persons with SCI. Identifying these potential factors that can assuage the adverse effects of pain on QOL is a first step toward active intervention to facilitate the adjustment of persons with SCI.

Role of self-efficacy on functional limitations among persons with spinal cord injury

OBJECTIVES

Spinal cord injury (SCI) results in mild to severe functional limitations, decreasing a person's ability to perform activities of daily living. This study aims to identify the influence of SCI characteristics and self-efficacy on functional limitations, controlling for sociodemographic factors.

METHODS

Participants for this cross-sectional descriptive study included 272 persons with SCI. The participants completed questionnaires on sociodemographic information, secondary physical conditions, self-efficacy, and functional limitations, using an online Qualtrics Survey. Multiple hierarchical regression analysis was performed to test the hypothesis.

RESULTS

Participants reported higher functional limitations on dressing the lower body and managing their bowels compared to other activities of daily living. The sociodemographics, injury characteristics, and self-efficacy collectively accounted for 66% variance in functional limitations. A higher level of secondary physical conditions and tetraplegia injury contributed to higher functional limitations. As hypothesized, greater self-efficacy significantly contributed to low functional limitations above and beyond sociodemographic and SCI-related variables.

DISCUSSION

Functional limitations following SCI are a pervasive challange in persons with SCI. Early recognition and management of secondary conditions and implementation of psychological interventions to strengthen self-efficacy in performing activities and managing secondary complications could potentially enhance functional independence and, ultimately, quality of life in this population.

Predictors of participation enfranchisement of wheelchair users with spinal cord injury in the United States

CONTEXT/OBJECTIVE

To investigate predictors of participation enfranchisement of individuals living with spinal cord injury (SCI) who use a wheelchair full-time.

DESIGN

Secondary data analysis of a cross-sectional study.

SETTING

Community, United States.

PARTICIPANTS

Participants were 59 wheelchair users (median age of 52.5 years, IQR = 21) with chronic SCI (>1 year after injury).

INTERVENTIONS

No intervention.

MAIN OUTCOME MEASURES

Participation enfranchisement was measured using the enfranchisement scale of the Community Participation Indicators (CPI). Dependent variables included importance of participation (CPI-Importance) and control over participation (CPI-Control) subscales of the CPI. Independent variables included demographics and clinical characteristics (age, sex, time since injury, level of injury), wheelchair skills, mobility level, symptoms of depression, and environmental barriers. Backward multivariable linear regression analyses were carried-out to identify predictors of CPI-Importance and CPI-Control.

RESULTS

Five predictors including mobility level, wheelchair skills, sex, level of injury, and symptoms of depression explained 57% (F = 14; P < 0.01) of the variance in CPI-Importance. Three predictors including mobility level, symptoms of depression, and environmental barriers explained 60% (F = 27; P < 0.01) of the variance in CPI-Control.

CONCLUSION

This study provides evidence of potential modifiable factors such as mobility, wheelchair skills, environmental barriers, and symptoms of depression that can influence importance of participation and control over participation of wheelchair users with SCI. The models presented in this study can serve as a conceptual framework to design effective interventions to improve participation enfranchisement of wheelchair users with SCI.

Quality of life after traumatic thoracolumbar spinal cord injury: a North Indian perspective

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

To determine the Quality of Life (QOL) in individuals with traumatic Spinal Cord Injury (SCI) of thoracolumbar region in Indian population, the factors affecting QOL and to compare this to other SCI populations.

SETTING

Tertiary level hospital in low-middle income country.

METHODS

93 individuals with SCI of minimum 1 year duration since injury were included in the study. Baseline demographics, socioeconomic parameters, and incidence of complications were ascertained. World Health Organisation Quality of Life-BREF (WHOQOL-BREF) score was used for measurement of QOL and was then compared to healthy Indian population and other SCI studies. Subgroup analysis was done to find out impact of variables on different domains of WHOQOL-BREF.

RESULTS

The median (IQR) age of the study participants was 35 (25, 45) with a male predominance. The median (IQR) duration since injury in the study population was 50 (26, 70) months. Lowest mean (SD) score was observed in the psychological domain -50.3 (12.1) and comparison to healthy Indian and high-income SCI populations revealed drastically decreased scores across all domains (p < 0.01). Employed individuals and housewives had significantly higher scores across all domains than unemployed individuals (p < 0.05). American Spinal Injury Association Impairment Scale (AIS) grade, socioeconomic status, pain and presence of complications all had significant impact on domain scores (p < 0.05). Multiple regression analysis revealed that mobilisation status and pain had the greatest effect on QOL.

CONCLUSION

Individuals with SCI have low QOL scores as compared to general Indian population as well as SCI individuals from a high resource setting. Pain and dependent mobilisation were found to be most significant predictors of poor WHOQOL-BREF domain scores. Housewives were found to have domain scores comparable to employed individuals. Presence of complications negatively impacts QOL.

Cognition and Quality of Life of People with Spinal Cord Injury

Objectives

The aim of this study was to assess the cognitive abilities of people with spinal cord injury (SCI) using the Edinburgh Cognitive and Behavior Amyotrophic Lateral Sclerosis Screen (ECAS), a tool designed for testing cognition in individuals with limited hand motor function. The impact of cognitive dysfunction on quality of life was also assessed.

Methods

Forty-one patients with SCI were assessed using ECAS, the brief version of the World Health Organisation Quality of Life questionnaire (WHOQOL-BREF), and the Spinal Cord Independence Measure.

Results

Overall, 28 of the 41 participants scored below the cut-off threshold for normal population in ECAS. The domains affected were language, 63%; memory, 51%; executive function, 44%; verbal fluency, 44%; and visuospatial skills, 24%. On multiple regression analysis, the ECAS total score moderately strongly explained the variance in the WHOQOL-BREF psychological (β = 0.428, t = 2.958, P = 0.005) and environmental (β = 0.411, t = 2.819, P = 0.008) domains. ECAS memory scores independently influenced WHOQOL-BREF physical (β = 0.398, t = 2.67, P = 0.011) and environmental (β = 0.37, t = 2.697, P = 0.010) domains. WHOQOL-BREF psychological scores were significantly influenced by ECAS executive scores (β = 0.415, t = 2.85, P = 0.007), whereas the social domain was not significantly influenced by ECAS scores.

Conclusions

It was feasible to use ECAS in individuals with SCI. Cognitive ability influenced the quality of life of people with SCI.

Social participation of individuals with spinal injury using wheelchairs in rural Tanzania after peer training and entrepreneurial skills training

Background

Individuals with spinal cord injury (SCI) in less-resourced settings reported barriers to community integration, including inaccessible rehabilitation services, restricted environments and limited social integration. Peer training and entrepreneurial skills training are provided by Motivation, a nonprofit organisation, and Moshi Cooperative University to enhance occupational engagement of individuals with SCI in less-resourced settings.

Objective

This study aimed to explore the impact of peer training and entrepreneurial skills training on the social participation of individuals with SCI living in Tanzania.

Method

Using a qualitative photovoice approach, 10 participants captured meaningful photos and provided captions according to five standardised questions (PHOTO technique) to convey their messages. Participants selected up to 34 photos that best illustrated their experiences in the community. A mixed inductive-deductive thematic analysis was guided by the International Classification of Functioning, Disability and Health.

Results

Two interrelated themes emerged: (1) 'influencing factors', which revealed how participants' inclusion in the community was influenced by their activities and personal and environmental factors and (2) 'empowerment', which highlighted participants' desire to advocate and promote awareness of needs and hopes.

Conclusion

Participants emphasised the importance of accessibility and equal opportunities. Whilst some were able to overcome obstacles, others experienced continued inaccessibility that inhibited meaningful occupations. Daily participation challenges of individuals with SCI in rural Tanzania were highlighted. Although the Motivation programmes were perceived to have powerful impacts on social participation, continued efforts and advocacy are needed to overcome accessibility issues and to meet the physical, psychological and social needs of Tanzanians living with SCI.

Contribution

This article highlights the importance of accessibility and equal opportunities for individuals with disability living in rural Tanzania. Peer-training and entrepreneurial programs offer community-based rehabilitation services that were perceived by people with disabilities to have a powerful impact on social participation and vocation. However, continued efforts and advocacy are needed to meet the needs of Tanzanians living with spinal cord injury.

An assessment of disability and quality of life in people with spinal cord injury upon discharge from a Bangladesh rehabilitation unit

DESIGN

Cross-sectional.

OBJECTIVES

The purpose of the study was to determine the level of disability and quality of life of people with spinal cord injury at the end of their inpatient rehabilitation at a rehabilitation center in Bangladesh. These outcomes were considered indicators of successful rehabilitation and a basis for comparing the success of reintegration into community.

SETTING

Center for the Rehabilitation of the Paralyzed, Bangladesh.

METHODS

Two standard structured questionnaires, the WHODAS 2.0 and WHOQOL-BREF, was used to collect data to assess level of disability and quality of life (QOL). Data were analyzed using Mann-Whitney-U test and Kruskal-Wallis test.

RESULTS

One hundred participants (91 men and 9 women) with SCI were recruited. Just prior to discharge from in-patient rehabilitation at CRP people with SCI perceived themselves overall as having on average a mild level of disability, and good QOL in physical, psychological, and environmental health domains. They indicated poor QOL in the social health domain. There were some specific differences in various WHODAS 2.0 Domains and overall scores when comparing age, gender, type and level of injury, occupation, and income. Between-group comparisons indicated that male participants had a significantly higher quality of life in the Environmental Health Domain and those with a paraplegic injury had a significantly higher quality of life in the Physical Health Domain.

CONCLUSION

By the end of their rehabilitation people with SCI had a relatively positive perception of level of disability and QOL. However, the results of other research has found that post-discharge their disability level increase and QOL decrease across all domains. Hence, it is recommended that more monitoring of level of disability and QOL is conducted post-discharge, along with a greater focus on community-based rehabilitation strategies and procedures to contribute to long-term reduction in level of disability and improved QOL.

Initiating daily acute intermittent hypoxia (dAIH) therapy at 1-week after contusion spinal cord injury (SCI) improves lower urinary tract function in rat

Spinal cord injury (SCI) above the level of the lumbosacral spinal cord produces lower urinary tract (LUT) dysfunction, resulting in impairment of urine storage and elimination (voiding). While spontaneous functional recovery occurs due to remodeling of spinal reflex micturition pathways, it is incomplete, indicating that additional strategies to further augment neural plasticity following SCI are essential. To this end, acute intermittent hypoxia (AIH) exposure has been proposed as a therapeutic strategy for improving recovery of respiratory and other somatic motor function following SCI; however, the impact of AIH as a therapeutic intervention to improve LUT dysfunction remains to be determined. Therefore, we examined the effects of daily AIH (dAIH) on both spontaneous micturition patterns and reflex micturition event (rME) behaviors in adult female Sprague-Dawley rats with mid-thoracic moderate contusion SCI. For these experiments, dAIH gas exposures (five alternating 3 min 12% O₂ and 21% O₂ episodes) were delivered for 7 consecutive days beginning at 1-week after SCI, with awake micturition patterns being evaluated weekly for 2-3 sessions before and for 4 weeks after SCI and rME behaviors elicited by continuous infusion of saline into the bladder being evaluated under urethane anesthesia at 4-weeks after SCI; daily normoxia (dNx; 21% O₂ episodes) served as a control. At 1-week post-SCI, both an areflexic phenotype (i.e., no effective voiding events) and a functional voiding phenotype (i.e., infrequent voiding events with large volumes) were observed in spontaneous micturition patterns (as expected), and subsequent dAIH, but not dNx, treatment led to recovery of spontaneous void frequency pattern to pre-SCI levels; both dAIH- and dNx-treated rats exhibited slightly increased void volumes. At 4-weeks post-SCI, rME behaviors showed increased effectiveness in voiding in dAIH-treated (compared to dNx-treated) rats that included an increase in both bladder contraction pressure (delta BP; P = 0.014) and dynamic voiding efficiency (P = 0.018). Based on the voiding and non-voiding bladder contraction behaviors (VC and NVC, respectively) observed in the BP records, bladder dysfunction severity was classified into mild, moderate, and severe phenotypes, and while rats in both treatment groups included each severity phenotype, the primary phenotype observed in dAIH-treated rats was mild and that in dNx-treated rats was moderate (P = 0.044). Taken together, these findings suggest that 7-day dAIH treatment produces beneficial improvements in LUT function that include recovery of micturition pattern, more efficient voiding, and decreased NVCs, and extend support to the use of dAIH therapy to treat SCI-induced LUT dysfunction.

Determinants of Quality of Life in Individuals With Spinal Cord Injury Using Structural Equation Modeling

OBJECTIVE

The objective of this study is to examine the interdependent associations between International Classification of Functioning, Disability and Health (ICF) domains and their relationship with environmental factors with regard to quality of life (QoL) in individuals with spinal cord injury (SCI).

DESIGN

Survey, cross-sectional study, and model testing using structural equation modeling.

SETTING

Two inpatient and outpatient SCI rehabilitation units, Sheba Medical Center and Loewenstein Hospital, Israel.

PARTICIPANTS

Convenience sample of 156 individuals with SCI (N=156).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

QoL assessed by the World Health Organization Quality of Life Assessment-BREF. Neurological impairment after SCI reflected by lesion completeness and neurologic level of injury as measured by the International Standards for Neurological Classification of Spinal Cord Injury. The Spinal Cord Independence Measure to assess SCI-related task performance. ICF Brief Core Sets composition scores to assess impairment in body structure and function domains, limitations in activities, restriction in participation constructs, and the effect of environmental factors within the ICF model.

RESULTS

Level of spinal cord injury and ICF Brief Core Sets composite score relating to activities and participation construct demonstrated a direct significant association with QoL. Moreover, a significant indirect association with QoL was found between the composite scores in ICF body structure and function and environmental factors, level of spinal cord injury, time since injury onset, and sex. Because the Spinal Cord Independence Measure was not related to QoL, we inferred that the categories related to instrumental activities of daily living and participation exert the most significant influence on QoL.

CONCLUSIONS

In order to optimize improvements in quality of life, current rehabilitation programs should target limitations specifically related to instrumental activities of daily living and participation restrictions. It may serve as a focal point for further development of current therapeutic models and analytical methods that optimize rehabilitation planning and decision making among both health care professionals and patients.

Long-term health and mobility of older adults following traumatic injury: a qualitative longitudinal study

PURPOSE

The aim of this study was to explore older adults' experiences of and approaches to managing their long-term health and mobility after traumatic injury.

METHODS

A longitudinal qualitative study was undertaken with older adults following traumatic injury in Victoria, Australia. Fifteen participants (≥65 years) were interviewed at three years post-injury (n = 15), and re-interviewed at four (n = 14) and five years (n = 12) post-injury. Using a framework approach, a longitudinal thematic analysis was performed.

RESULTS

Older age at the time of injury was identified by participants as a key factor influencing their recovery. Many participants reported actively attempting to regain their strength and fitness in the first five years following injury. However, their age, injury impacts, other health conditions, and weight gain made it difficult to achieve recovery goals. Many older adults reported a decline in their physical function over time. While these experiences and persistent disability constrained or changed the quality of social relationships, community participation, and independence, several participants described adapting to their functional limitations, and managing their secondary conditions over time.

CONCLUSION

In our cohort, the intertwined combination of ageing, injury, and comorbid conditions negatively affected health and mobility, reinforcing the need for preventative strategies.Implications for rehabilitationOlder adults recovering from traumatic injury may benefit from specialised care pathways that offer long-term and tailored therapies, with programs and services specific to their needs and goals.An integrated service approach by injury insurers, health care, primary care, disability, and aged care could more clearly identify and effectively address the individual needs and goals of older adults with complex conditions.Health and social services that work with people with injuries to develop personalised coping strategies can reduce anxiety related to uncertainty about the future, promote well-being, and support participation in valued activities.

The role of mindfulness in quality of life of persons with spinal cord injury: a cross-sectional study

BACKGROUND

Quality of life is considered the most overarching psychosocial adaptation outcome following the rehabilitation of persons with spinal cord injury. Literature suggests that the quality of life of persons with spinal cord injury is determined by many personal and psychological factors, including mindfulness. This study aimed to identify the direct and indirect effect of mindfulness on the quality of life of persons living with spinal cord injury.

METHODS

Participants consisted of 231 members of three spinal cord injury organizations in the United States: United Spinal Association, North American Spinal Cord Injury Consortium, and Paralyzed Veterans of America-Wisconsin Chapter. The participants completed a set of standardized self-report questionnaires in an online Qualtrics survey. A hierarchical regression analysis was performed to identify the contribution of mindfulness to quality of life, controlling for sociodemographic and injury-related factors. A serial mediation analysis was performed to examine the indirect effect of mindfulness on quality of life.

RESULTS

In the hierarchical regression analysis, sociodemographic and injury-related factors (i.e., age, gender, race, marital status, education, employment, level and completeness of injury, comorbidities, frequency of hospitalization, pain intensity, and functional limitation) and mindfulness explained 59% variance on quality of life of the participants with spinal cord injury. Mindfulness uniquely contributed to the higher quality of life above and beyond sociodemographic and injury-related variables. In the serial mediation analysis, pain and functional limitation did not significantly mediate the relationship between mindfulness and quality of life. However, the indirect effects of mindfulness on functional limitation and quality of life through pain were significant.

CONCLUSION

The findings underscore the vital role of mindfulness in improving the quality of life of persons with spinal cord injury. Implications of these findings for future research and clinical practice are discussed.

Preliminary validation study of the WHO quality of life (WHOQOL) scales for people with spinal cord injury in Mainland China

OBJECTIVE

To validate the WHOQOL Scales (WHOQOL-BREF and WHOQOL-DIS module) for people with spinal cord injury in Mainland China.

DESIGN

Cross-sectional study.

SETTING

Shanghai Sunshine Rehabilitation Center.

PARTICIPANTS

249 adults with SCI who were admitted to a rehabilitation training program between 2017 and 2019.

INTERVENTIONS

Not applicable.

METHODS

Questionnaires about personal and injury characteristics, the WHOQOL Scales, global QOL, Zung Self-Rating Anxiety/Depression Scale (SAS/SDS), and Community Integration Questionnaire (CIQ) were administrated. Floor and ceiling effects, reliability, and validity analyses were tested.

RESULTS

The 8 domains of the WHOQOL Scales showed no floor or ceiling effects. Cronbach alpha values of the WHOQOL-BREF and the WHOQOL-DIS were 0.93 and 0.78, respectively. Test-retest reliability was good for the WHOQOL Scales. Satisfactory criterion-related validity was shown by the correlation analysis among the WHOQOL Scales, SAS/SDS, CIQ, and global QOL. Good item-domain correlations (>0.50) were found for 38 items of the 39-item WHOQOL Scales, excepting the "impact of disability" (0.48) of the WHOQOL-DIS. Confirmatory Factor Analysis (CFA) supported a construct of the WHOQOL-DIS as made of four domains: autonomy, social inclusion, social activities, and discrimination. CFI and RMSEA values were 0.91 and 0.07, respectively, for the four-domain structure WHOQOL-DIS, with a higher-order factor. WHOQOL-BREF domains and WHOQOL-DIS scores showed the predicted pattern among a priori known groups.

CONCLUSION

The WHOQOL Scales are valid and reliable, and they can be used to measure QOL in people with SCI in China. We suggest the WHOQOL-DIS be analyzed as one general item constituting a single 12-item domain.

Restored Life of Elite Athletes after Spinal Cord Injury

Spinal cord injury (SCI) affects every aspect of human life: medical, psychological, social, material. People with SCI face a variety of secondary conditions (e.g., chronic pain, urinary tract infections, cognitive impairment) that place a significant emotional burden, resulting in an increased risk of depression and reduced quality of life. The purpose of this study was to better understand the coping strategies and to identify factors that promote or hinder the successful adjustment of elite athletes after SCI. Individual semi-structured interviews were conducted with eight top athletes after spinal cord injury. The interviews were recorded, transcribed, and then thematically analyzed using MAXQDA software. Thematic analysis identified the following categories: coping, athletic identity, and adjustment. The results of the study indicate that loss of functional ability does not cause loss of athlete identity. Elite athletes live a life consistent with this identity, attempting to maintain it despite the loss of physical fitness. Involvement in sports provides meaning and is a positive factor in the process of disability acceptance, which is essential in the process of adjustment to injury and also provides group belonging.

Access and engagement with places in the community, and the quality of life among people with spinal cord damage

OBJECTIVES

This study aims to investigate the association between self-reported accessibility and engagement with health services and places in the community, and quality of life (QOL) for people with spinal cord damage (SCD).

DESIGN

Cross-sectional survey.

SETTING

Community.

PARTICIPANTS

Two-hundred and sixty-six people with a SCD residing in Australia (M_age = 62.34, SD_age = 15.95).

OUTCOME MEASURE

The International Spinal Cord Injury Quality of Life Basic Data Set.

RESULTS

Univariate regressions demonstrated that accessing a higher number of places in the community was significantly associated with favorable self-reported psychological health (β = .160, P < .01), physical health (β = .144, P < .01), overall well-being (β = .206, P < .01), and QOL (β = .187, P < .01). In contrast, reporting a higher number of inaccessible places was significantly associated with unfavorable self-reported psychological health (β = -.171, P < .01), physical health (β = -.270, P < .001), overall well-being (β = -.238, P < .001), and QOL (β = -.244, P < .001). Being older and living with injury or onset of damage longer were significantly associated with favorable scores across all outcomes (P < .01) except physical health.

CONCLUSIONS

Community engagement can have a considerable impact on the self-reported health and QOL of people with SCD. Interventions aimed at increasing community engagement, particularly for people who have recently experienced SCD are warranted.

Life satisfaction and athletic identity among Olympic para-alpine skiers: a survey

The objective of this study was to examine life satisfaction and athletic identity among para-alpine skiers and explore their associations with sociodemographic, sports practice, and disability-related characteristics of the participants. The respondents to the on-site survey were 129 para-alpine ski racers with acquired disability from 33 countries on all five continents who competed in the Paralympic games in Sochi (aged 16-53 years, mean and median 30 years, 100 men). Two self-developed assessment instruments were used - a 7-point Likert-type life-satisfaction questionnaire probing seven domains (health, family, education, freedom, friends, travelling, and self) and the Athletic Identity Scale (AIS; possible score range 17-85). The independence between life-satisfaction items was confirmed by low interitem correlations (largest absolute value <0.25, 15 of 21, and <0.15). The estimated internal-consistency reliability (Guttman lambda-2) of AIS was 0.65. The reported life satisfaction was very high (median of 6 for all domains except education, where it was 5). Like life-satisfaction ratings, the AIS scores were also very high on average (mean and median score 81). In general, the level of life satisfaction and athletic identity were not notably associated with sociodemographic, sports practice, and disability characteristics of the participants. The likely reason is high average and, hence, low variability of life-satisfaction ratings, as well as imperfect metric characteristics of the AIS. Nonetheless, the overall findings encourage further research into factors that drive the participation of disabled athletes in (winter) Paralympic games and the possible role of the rehabilitation process in this regard.

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.

Influences on Participation in Life After Spinal Cord Injury: Qualitative Inquiry Reveals Interaction of Context and Moderators

Background

Greater understanding of the influences on participation in life after spinal cord injury (SCI) can inform rehabilitation theory and practice. Careful qualitative inquiry can reveal subjective meanings associated with the relevant experiences, strategies, and perceptions of those with lived experience of SCI. A search of literature, followed by a thematic synthesis of qualitative studies, was undertaken to bring together these insights in a meaningful way.

Methods

The research question guiding the literature review and synthesis was, What do people with SCI perceive to be the influences on their participation in life? Three critical databases were searched for qualitative studies examining influences on participation in life after SCI. Peer-reviewed studies published after 2006, involving adults with SCI living in countries with advanced economies, were included. Data were extracted from 24 articles and subjected to three-level thematic synthesis—the coding of primary data from the studies, the development of descriptive themes based on an organization of those codes, and the generation of analytical themes.

Results

The synthesis yielded five analytical themes, supported by 17 descriptive themes. The analytical themes were (1) external contextual influences, (2) personal physical context, (3) personal psychological context, (4) potential moderators of participation outcomes, and (5) temporal dimensions of participating in life after SCI.

Interpretation

These themes highlight the complex interactions that shape participation from the perspective of people with SCI. Closer examination of the potential moderators may provide insights into effective rehabilitation interventions.

Conclusions

Synthesis of qualitative inquiry provides valuable insights into the perceptions of influences on participation in life from the point of view of people with SCI. The findings of this synthesis are instructive for rehabilitation theory and practice. It can complement what we learn from using the ICF to understand participation.

The Cardiorespiratory Demands of Treadmill Walking with and without the Use of Ekso GT™ within Able-Bodied Participants: A Feasibility Study

Individuals with neurological impairments tend to lead a predominantly sedentary lifestyle due to impaired gait function and mobility. This may be detrimental to health by negatively impacting cardiorespiratory fitness and muscular strength, and increasing the risk of developing secondary health problems. Powered exoskeletons are assistive devices that may aid neurologically impaired individuals in achieving the World Health Organisation's (WHO) physical activity (PA) guidelines for health. Increased PA should elicit a sufficient cardiorespiratory stimulus to provide health benefits to exoskeleton users. This study examined the cardiorespiratory demands of treadmill walking with and without the Ekso GT™ among able-bodied participants. The Ekso GT™ is a powered exoskeleton that enables individuals with neurological impairments to walk by supporting full body mass with motors attached at the hip and knee joints to generate steps. This feasibility study consisted of one group of healthy able-bodied individuals (n = 8). Participants completed two 12 min treadmill walking assessments, one with and one without the Ekso GT™ at the same fixed speed. Throughout each walking bout, various cardiorespiratory parameters, namely, volume of oxygen per kilogram (kg) of body mass (V˙O2·kg-1), volume of carbon dioxide per kg of body mass (V˙CO2·kg-1), respiratory exchange ratio (RER), ventilation (V˙E), heart rate (HR), and rate of perceived exertion (RPE), were recorded. Treadmill walking with Ekso GT™ elevated all recorded measurements to a significantly greater level (p ≤ 0.05) (except RER at 1 km·h-1; p = 0.230) than treadmill walking without the Ekso GT™ did at the same fixed speed. An increased cardiorespiratory response was recorded during treadmill walking with the exoskeleton. Exoskeleton walking may, therefore, be an effective method to increase PA levels and provide sufficient stimulus in accordance with the PA guidelines to promote cardiorespiratory fitness and subsequently enhance overall health.

Factors Influencing Incidence of Wheelchair Repairs and Consequences Among Individuals with Spinal Cord Injury

OBJECTIVE

To investigate the frequency and consequences of wheelchair repairs, looking at the relationship to usage, components, out-of-pocket costs, number of days affecting the user, and factors associated with the need for repairs or consequences.

DESIGN

Survey, cross-sectional.

SETTING

Nine spinal cord injury (SCI) Model Systems centers.

PARTICIPANTS

Wheelchair users with SCI (N=533).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Cost and incidence of wheelchair repairs and consequences and wheelchair usage within the past 6 months.

RESULTS

A total of 310 participants (56%) reported repairs, 127 (42%) of whom experienced at least 1 adverse consequence lasting a median of 5 days (interquartile range [IQR], 2-17.3 days). Repair rates were highest for the seating system, electronics, and tires. Participants were most often stranded at home or forced to use a backup chair. Median out-of-pocket costs were $150 (IQR, $50-$620). Active users, based on type of mobility and terrain, experienced more repairs and consequences than less active users. Repairs were more common among those who were Black (odds ratio [OR], 2.42) or power wheelchair (PWC) users (OR, 1.84), whereas consequences were more common among those who were Black (OR, 2.27), PWC (OR, 2.08) or power assist users (OR, 2.76), and those who had public insurance (OR, 1.70).

CONCLUSIONS

Wheelchair repairs continue to affect more than 50% of wheelchair users with significant financial and personal cost. High repair rates limited participation inside and outside of the home. Consequences lasted longer than 2 weeks for many and may be minimized by a working backup chair. Disparities exist based on participant and wheelchair factors; repairs and adverse consequences appear to hit those most vulnerable with the least financial resources. Costs may be a barrier to repair completion for some individuals. This ongoing problem of high repair rates and their associated effects requires action such as higher standards, access to quicker service, and better training of users on wheelchair maintenance and repair.

Assessment of the unmediated relationship between neurological impairment and health-related quality of life following spinal cord injury

Objective: To assess the unmediated association between neurological impairment and quality of life (QoL) among persons with spinal cord injury (SCI), in the context of both early post-acute and long-term rehabilitation settings.Design: An observational prospective cross-sectional study.Setting: Two neurological rehabilitation centers, specializing in spinal cord injury, within a university hospital.Methods: 156 adults with spinal cord injury in the early post-acute and chronic stages of rehabilitation.Outcome Measures: Participants were categorized into tetraplegia or paraplegia groups based on neurological level of injury, and into complete or incomplete groups based on American Spinal Injury Association (ASIA) Impairment Scale (AIS) score. QoL was assessed by means of the World Health Organization Quality of Life Assessment-BREF (WHOQOL-BREF), Satisfaction with Life Scale (SWLS), Life Satisfaction Questionnaire (LISAT-9), and Personal Well-Being Index (PWI).Results: WHOQOL-BREF and PWI predicted Level of Injury group classification and WHOQOL-BREF predicted Setting group classification. None of the questionnaires differentiated between the Type of Injury groups. At the early post-acute stage of rehabilitation, the QoL scores of participants with tetraplegia and paraplegia did not differ significantly, while significantly higher QoL scores were revealed in paraplegics in the long-term setting group.Conclusions: A direct, unmediated effect of severity of neurological impairment was revealed with the WHOQOL-BREF, which distinguished between the tetraplegia and paraplegia groups, but not between the complete and incomplete injuries. QoL was significantly higher in paraplegia than in tetraplegia following the early post-acute stage of rehabilitation.

Daily Variation in Sleep Quality is Associated With Health-Related Quality of Life in People With Spinal Cord Injury

OBJECTIVE

Although sleep difficulties are common after spinal cord injury (SCI), little is known about how day-to-day fluctuations in sleep quality affects health-related quality of life (HRQOL) among these individuals. We examined the effect of sleep quality on same-day HRQOL using ecological momentary assessment methods over a 7-day period.

DESIGN

Repeated-measures study involving 7 days of home monitoring; participants completed HRQOL measures each night and ecological momentary assessment ratings 3 times throughout the day; multilevel models were used to analyze data.

SETTING

Two academic medical centers.

PARTICIPANTS

A total of 170 individuals with SCI (N=170).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Daily sleep quality was rated on a scale of 0 (worst) to 10 (best) each morning. Participants completed end-of-day diaries each night that included several HRQOL measures (Sleep Disturbance, Sleep-related Impairment, Fatigue, Cognitive Abilities, Pain Intensity, Pain Interference, Ability to Participate in Social Roles and Activities, Depression, Anxiety) and ecological momentary assessment ratings of HRQOL (pain, fatigue, subjective thinking) 3 times throughout each day.

RESULTS

Multilevel models indicated that fluctuations in sleep quality (as determined by end-of-day ratings) were significantly related to next-day ratings of HRQOL; sleep quality was related to other reports of sleep (Sleep Disturbance; Sleep-related Impairment; Fatigue) but not to other aspects of HRQOL. For ecological momentary assessment ratings, nights of poor sleep were related to worse pain, fatigue, and thinking. Generally, sleep quality showed consistent associations with fatigue and thinking across the day, but the association between sleep quality and these ecological momentary assessment ratings weakened over the course of the day.

CONCLUSIONS

Findings highlight the important association between sleep and HRQOL for people with SCI. Future work targeting sleep quality improvement may have positive downstream effects for improving HRQOL in people with SCI.

Cognitive function, quality of life, and aging: relationships in individuals with and without spinal cord injury

Background: Correlations between aging, cognitive impairment and poor quality of life (QOL) have been observed for many patient populations.Objective: The purpose of this study was to examine these correlations in individuals with and without spinal cord injury (SCI).Methods: 23 individuals with complete SCI and 20 individuals without SCI ("NON") underwent assessment of cognitive function via the NIH Toolbox for Neurological and Behavioral Function. Participants self-rated QOL via global and symptom/domain-specific measures.Results: SCI rated global QOL to be lower than NON for the EQ-5D QALY (p < .001), but not the EQ-5D VAS, which imposes no penalty for wheeled mobility. Low QOL clustered mainly in domains pertaining to physical function/symptoms. Participants with SCI reported high QOL for positive affect/well-being and resilience. Cognitive function in SCI did not differ from NON. However, strong correlations between age and cognition observed in NON (all R² > 0.532) were absent in SCI. Significant correlations between cognition and QOL were prevalent for NON but not for SCI.Conclusions: Dissociation of age, cognition and QOL occurred with SCI. Divergence between EQ-5D QALY and VAS suggests that individuals with SCI may recalibrate personal assessments of QOL in ways that minimize the importance of mobility impairment.

Advanced approaches to regenerate spinal cord injury: The development of cell and tissue engineering therapy and combinational treatments

Spinal cord injury (SCI) is a central nervous system (CNS) devastate event that is commonly caused by traumatic or non-traumatic events. The reinnervation of spinal cord axons is hampered through a myriad of devices counting on the damaged myelin, inflammation, glial scar, and defective inhibitory molecules. Unfortunately, an effective treatment to completely repair SCI and improve functional recovery has not been found. In this regard, strategies such as using cells, biomaterials, biomolecules, and drugs have been reported to be effective for SCI recovery. Furthermore, recent advances in combinatorial treatments, which address various aspects of SCI pathophysiology, provide optimistic outcomes for spinal cord regeneration. According to the global importance of SCI, the goal of this article review is to provide an overview of the pathophysiology of SCI, with an emphasis on the latest modes of intervention and current advanced approaches for the treatment of SCI, in conjunction with an assessment of combinatorial approaches in preclinical and clinical trials. So, this article can give scientists and clinicians' clues to help them better understand how to construct preclinical and clinical studies that could lead to a breakthrough in spinal cord regeneration.

Is Self-Efficacy Related to the Quality of Life in Elite Athletes after Spinal Cord Injury?

Background: A spinal cord injury (SCI) is a traumatic event that affects every aspect of life: physical, mental, economic, and social. The main aim of this study was to investigate self-efficacy, quality of life, and their correlations among outstanding athletes who have suffered spinal cord injuries, and to determine whether these individuals have specific psychological characteristics that contribute to a better quality of life. Methods: The study involved nine athletes with at least national-level achievements in sports prior to an SCI. Participation in the study consisted of an interview via an online communicator, followed by an online questionnaire consisting of a personal questionnaire and two scales: The World Health Organization Quality of Life Scale (WHOQoL-BREF), and the General Self-Efficacy Scale (GSES). Results: Spearman’s correlation showed a correlation between general self-efficacy, perception of quality of life, and satisfaction with own physical health, as well as psychological resources and environmental support. Conclusions: Involvement in an environment that was important to the injured person before the accident, in either a passive (in the absence of functional capacity) or active form, promotes a greater sense of self-efficacy and good QoL, regardless of the time that has passed since the accident, and despite high levels of pain or secondary health issues. To fill the gap in professional long-term healthcare services for athletes after SCIs, intervention programs should be considered that support self-efficacy, which is an important factor that can be subject to improvement.

Relationships Between Functionality, Depression, and Anxiety With Community Integration and Quality of Life in Chronic Traumatic Spinal Cord Injury

OBJECTIVES

The aims of the study were (1) to identify relationships between functional and psychological aspects with community integration and quality of life assessments in people with chronic traumatic spinal cord injury and (2) to analyze clinical and demographic predictors of quality of life dimensions.

DESIGN

This is an observational cohort study, and correlation coefficients were calculated between the Functional Independence Measure, the Hospital Anxiety and Depression Scale, the Community Integration Questionnaire, and the World Health Organization Quality of Life-BREF dimensions (physical [D1], psychological [D2], social [D3], and environmental [D4]). Quality of life predictors were identified using multiple linear regression analyses.

RESULTS

Nine hundred seventy-five people with traumatic spinal cord injury assessed since 2007-2020 were included. The Community Integration Questionnaire home integration correlated strongly with the Functional Independence Measure self-care (r = 0.74) and transfers (r = 0.62) for participants with tetraplegia. The specific Hospital Anxiety and Depression Scale items (known as the anhedonia subscale) correlated strongly with D1 (r = -0.65), D2 (r = -0.69), D3 (r = -0.53), and D4 (r = -0.51) for participants with paraplegia and D1 (r = -0.53), D2 (r = -0.61), D3 (r = -0.47), and D4 (r = -0.53) for participants with tetraplegia. The Hospital Anxiety and Depression Scale-depression was the most relevant predictor of D1 (β = -0.61) and D2 (β = -0.76).

CONCLUSIONS

The Functional Independence Measure transfers and self-care were strongly associated with the Community Integration Questionnaire home integration (in participants with tetraplegia). Anhedonia was strongly related to all four World Health Organization Quality of Life-BREF Scale dimensions, being the Hospital Anxiety and Depression Scale-depression the most relevant predictor of D1 and D2.

Prevalence of sleep-disordered breathing in people with tetraplegia-a systematic review and meta-analysis

STUDY DESIGN

Systematic review with meta-analysis.

OBJECTIVES

To determine the prevalence of sleep-disordered breathing (SDB) in people with tetraplegia and to identify the characteristics associated with SDB.

METHODS

A systematic literature search using Medline, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL) and grey literature sources was conducted using a combination of spinal cord injury (SCI) and SDB related terms. Articles were restricted to publication dates between 1/1/2000 and 4/9/2020 and with objectively measured SDB with an overnight sleep study. The frequency of SDB stratified by the apnoea hypopnea index (AHI) was extracted and weighted averages, using a random effects model, were calculated with 95% confidence intervals. Sub-group analyses were performed where possible.

RESULTS

Twelve articles were included in the review; of these nine were included in meta-analysis (combined sample = 630). Sample sizes and case detection methods varied. Reported SDB prevalence rates ranged from 46 to 97%. The prevalence of at least mild (AHI ≥ 5), moderate (AHI ≥ 15) and severe (AHI ≥ 30) SDB were 83% (95% CI = 73-91), 59% (46-71) and 36% (26-46), respectively. Sub-group analyses found that prevalence increased with age (p < 0.001). There were no statistically significant differences in SDB prevalence by sex (p = 0.06), complete/incomplete SCI (p = 0.06), body mass index (p = 0.07), acute/chronic SCI (p = 0.73) or high/low level of cervical SCI (p = 0.90).

CONCLUSION

Our results confirm that SDB is highly prevalent in people with tetraplegia, and prevalence increases with age. The high prevalence suggests that routine screening and subsequent treatment should be considered in both acute and community care.

Media portrayal of spinal cord injury and its impact on lived experiences: a phenomological study

STUDY DESIGN

This is a qualitative, phenomenological study.

OBJECTIVE

To investigate media portrayal of spinal cord injury (SCI) as perceived by people with SCI and explore its impact on their lived experience.

SETTING

People with SCI living in Australia.

METHOD

Twenty-four participants, recruited using purposive and snowball sampling, completed in-depth, semi-structured interviews. Thematic data analysis followed an inductive, iterative process.

RESULTS

Participants perceived media portrayed SCI through a narrow lens, describing how people with SCI were 'absent' or portrayed as either 'pity or pedestal'. Participants said media portrayed an inaccurate picture of their lived experience that perpetuated misunderstandings of SCI. This portrayal fostered unreasonable public expectations and assumptions about living with SCI, which presented in the participant's lives as uncomfortable interactions and inappropriate remarks. The impact for participants was a burden to explain SCI and justify what it meant for them. People with SCI would like media to portray a broader, more authentic representation of SCI to improve public understanding and to reduce the negative impact on their lives.

CONCLUSION

People with SCI perceived a narrow and inaccurate portrayal of SCI in media that overlooked potential quality of life, overshadowed health and life domains they considered important and reinforced the idea that SCI can be overcome. People with SCI were mostly concerned with what was absent in media portrayal of SCI rather than what was present. Action for change lies in promoting information, expanding narratives and raising awareness to diverse abilities of people with SCI.

Age Categories Differences in Subjective Quality of Life of Women with Physical Disabilities

Objective

The objective of the study was to analyse and compare the subjective quality of life (S-QoL) of women with physical disabilities (PDs) through satisfaction with the quality of life domains and the overall quality of life assessment.

Methods

The sample comprised of women with PDs (n=137), divided into 4 age categories: 19-29 yrs. (n=53); 30-44 yrs. (n=25); 45-59 yrs. (n=24) and over 60 yrs. (n=35). The Subjective Quality of Life Analyses questionnaire and the WHO User Manual were used as a primary research method. The Wilcoxon Signed Rank Test was used to assess the differences between QoLDs, Kruskal Wallis test to assess differences in S-QoL among four independent groups and Mann Whitney U-test between two age categories.

Results

The highest satisfaction in all age categories of women was found in the social relations domain, and in the 19-29 yr-old women equally in the social relations and physical health domains. The highest dissatisfaction was reported with the psychological health and environment domains. The key finding is that the main differences are between the youngest category (aged 19-29 yrs) and the three older categories with regard to physical health, environment and overall QoL.

Conclusions

It is necessary to continue this line of research with a greater focus on exploring the ways in which the psychological health domain can be improved as an integral part of S-QoL, and to also focus on the QoL indicators that make up the environment domain and search for ways to enhance these.

Changes in health-related quality of life among older adults aging with long-term spinal cord injury

STUDY DESIGN

Cross-sectional and longitudinal.

OBJECTIVES

To (i) describe health-related quality of life (HRQoL) and changes over 6 years in older adults aging with long-term spinal cord injury (SCI) and (ii) investigate how changes in HRQoL are associated with age, gender, and injury characteristics.

SETTING

Community in southern Sweden.

METHODS

From the initial 123 participants (years 2011-2012) in the Swedish Aging with Spinal Cord Injury Study (SASCIS), 77 individuals (32% women, C1-L3, AIS A-D, median age 66 years, median time since injury 31 years, 30% complete injuries) were assessed 6 years later. HRQoL was rated with the Spinal Cord Injury Quality of Life Questionnaire (SCI QL-23). Associations were investigated using multivariable linear regression analyses.

RESULTS

The median rating of global QoL (scale range 0-100) was relatively high at both assessments (67 and 83, respectively). There was a large variability in all HRQoL-domains and no significant changes over 6 years. As compared to an AIS D injury, a tetraplegia AIS A-C injury and tetraplegia and paraplegia AIS A-C injuries were associated with positive change in depressive symptoms and global QoL, respectively.

CONCLUSIONS

Older adults aging with long-term SCI show large variations in all HRQoL-domains and have the potential to maintain a high and stable level of HRQoL over time. Persons with AIS D injuries may need increased attention to mitigate negative changes in depressive symptoms and global QoL. Further studies are needed to identify modifiable factors associated with changes in HRQoL in older adults aging with long-term SCI.

Quality of Life after Spinal Cord Injury: A Multiple Case Study Examination of Elite Athletes

A three-times World Champion in BMX (an acronym for Bicycle Motocross) dirt jumps, a Junior World Champion in ski jumping, and a European karate Champion sustained spinal cord injuries at the cervical and thoracic level. Such a severe trauma is tantamount to the end of a professional sporting career. In such a situation, the athlete’s life significantly changes in every aspect of it: health, professional, and social. The greatest sports champions have not yet been portrayed in the context of a strategy they used to deal with an abrupt end of a professional career due to severe injury. A semi-structured interview was conducted with study participants who additionally filled out the WHO Quality of Life Scale. This multiple case series presents the quality of life in elite athletes as well as the social activities they have undertaken regardless of the tragic accident. The results of the research indicate that these people are characterized rather by a positive sense of quality in life, and the way they function in a difficult situation is an inspiration to others.

Empirical Validity of a Generic, Preference-Based Capability Wellbeing Instrument (ICECAP-A) in the Context of Spinal Cord Injury

BACKGROUND

Assessing the validity of generic instruments across different clinical contexts is an important area of methodological research in economic evaluation and outcomes measurement.

OBJECTIVE

Our objective was to examine the empirical validity of a generic, preference-based capability wellbeing instrument (ICECAP-A) in the context of spinal cord injury.

METHODS

This study consisted of a secondary analysis of data collected using an online cross-sectional survey. The survey included questions regarding demographics, injury classifications and characteristics, secondary health conditions, quality of life and wellbeing, and functioning in activities of daily living. Analysis comprised the descriptive assessment of Spearman's rank correlations between item-/dimension-level data for the ICECAP-A and four preference-based health-related quality of life (HRQoL) instruments, and discriminant and convergent validity approaches to examine 21 evidence-informed or theoretically derived constructs. Constructs were defined using participant and injury characteristics and responses to a range of health, wellbeing and functioning outcomes.

RESULTS

Three hundred sixty-four individuals completed the survey. Mean index score for the ICECAP-A was 0.761; 12 (3%) individuals reported full capability (upper anchor; score = 1), and there were no reports of zero capabilities (lower anchor; score = 0). The strongest correlations were dominated by items and dimensions on the comparator (HRQoL) instruments that are non-health aspects of quality of life, such as happiness and control over one's life (including self-care). Of 21 hypothesised constructs, 19 were confirmed in statistical tests, the exceptions being the exploratory hypotheses regarding education and age at injury.

CONCLUSION

The ICECAP-A is an empirically valid outcome measure for assessing capability wellbeing in people with spinal cord injury living in a community setting. The extent to which the ICECAP-A provides complementary information to preference-based HRQoL instruments is dependent on the comparator.

Dual spinal cord injury: a case of acute traumatic T9 AIS A spinal cord injury complicated by transverse myelitis

INTRODUCTION

While the general principles of treatment of TM are agreed upon, the rarity of the disease has made determining its clinical course and etiology quite difficult. This report aims to inform these debates by demonstrating the susceptibility of at least one individual to transverse myelitis following an acute SCI.

CASE PRESENTATION

This case report follows the clinical course of a 17 year old. Caucasian female that contracted transverse myelitis (TM) following an acute traumatic spinal cord injury. This patient originally presented as a T9 AIS A traumatic SCI, and was then re-graded as C6 AIS A SCI following diagnosis of TM. She was later seen in clinic for 6-month follow-up and displayed post-trauma baseline scores for both strength and sensation, indicating nearly complete recovery.

DISCUSSION

In addition, this report demonstrates the importance of adequate clinical management of TM in practical terms of patient performance on clinical exams. This report also adds to the existing body of evidence suggesting early intervention is associated with better functional outcomes.

Implantable Osmotic Transport Device Can Reduce Edema After Severe Contusion Spinal Cord Injury

Recent findings from the ISCoPe study indicate that, after severe contusion to the spinal cord, edema originating in the spinal cord accumulates and compresses the tissue against the surrounding dura mater, despite decompressive laminectomy. It is hypothesized that this compression results in restricted flow of cerebrospinal fluid (CSF) in the subarachnoid space and central canal and ultimately collapses local vasculature, exacerbating ischemia and secondary injury. Here we developed a surgically mounted osmotic transport device (OTD) that rests on the dura and can osmotically remove excess fluid at the injury site. Tests were performed in 4-h studies immediately following severe (250 kD) contusion at T8 in rats using the OTD. A 3-h treatment with the OTD after 1-h post injury significantly reduced spinal cord edema compared to injured controls. A first approximation mathematical interpretation implies that this modest reduction in edema may be significant enough to relieve compression of local vasculature and restore flow of CSF in the region. In addition, we determined the progression of edema up to 28 days after insult in the rat for the same injury model. Results showed peak edema at 72 h. These preliminary results suggest that incorporating the OTD to operate continuously at the site of injury throughout the critical period of edema progression, the device may significantly improve recovery following contusion spinal cord injury.

Family quality of life: perceptions of parents of children with developmental disabilities in Bosnia and Herzegovina

The goal of the present study was to assess the family quality of life (FQOL) in families with children with developmental disabilities in Bosnia and Herzegovina. We examined the FQOL in relation to parents' demographic variables (gender, age, employment status), children's gender and age, type of children's disability (mild and moderate intellectual disability, autism spectrum disorder) and parent's depression, anxiety, and stress levels. The sample consisted of 270 parents of children with disabilities; 90 parents of children with autism spectrum disorder, 90 parents of children with mild intellectual disability, and 90 parents of children with moderate intellectual disability. We also included a control group of 90 parents of typically developing children. The results of this study showed that parents of children with autism spectrum disorder and parents of children with moderate intellectual disability had statistically significantly lower FQOL than parents of children with mild intellectual disability and parents of typically developing children. Child's gender had a significant effect on FQOL. Also, depression, anxiety and stress levels significantly affected FQOL, while the parents' gender, age, and employment status did not have a significant effect. Implications of these findings are discussed and some measures on supporting parents are proposed.

Narratives of long-term resilience: two cases of women aging with spinal cord injury

INTRODUCTION

Spinal cord injury (SCI) is a life-changing event that drastically affects a person's sense of identity, ability to participate, and quality of life (QOL). Researchers studying the coping process have often focused on identifying maladaptive behaviors and barriers, and less on positive psychology approaches emphasizing individual strengths. More recently, positive psychology constructs, such as resilience, have received greater attention from SCI researchers. Early and ongoing recognition of resilience in patients with SCI may provide important information to clinicians about adjustment and long-term management. Our purpose is to document patterns and indicators of resilience, using a narrative approach, during various stages of adjustment following SCI.

CASE PRESENTATIONS

Narrative case presentations are deriving from in-depth qualitative interviews with two women aged 63 and 52, living with SCI. Both had complete motor neurological injuries that incurred at 27 and 35 years, respectively. Each woman was interviewed twice, approximately 10 years apart (age 63 and 52, and age 54 and 42). Each demonstrated high levels of resilience through evolving roles of family and caregivers, inner personal strength, and participation in their respective communities. We highlight differences, similarities, and evolution of resilience factors in and between each case.

DISCUSSION

These cases illustrate examples of long-term resilience, adding richness to the resilience construct. Results provide knowledge that can be used to target rehabilitation interventions toward successful coping styles. In sharing these cases, we hope to assist clinicians and researchers to better recognize patterns of resilience in their own patients and study participants.

Quality of life among men with spinal cord injury in Lebanon: A case control study

BACKGROUND

Spinal cord injury (SCI) is a permanent disability which negatively affects individuals' health and particularly their quality of life.

OBJECTIVE

To assess the quality of life (QoL) among Lebanese men with spinal cord injury and to compare it to a healthy control group.

METHODS

A case control study was conducted. Fifty-one Lebanese patients with spinal cord injury and 51 age- sex-matched healthy persons were included in the study.

RESULTS

Compared to healthy controls, the mean scores of eight domains of SF-36 were significantly lower in SCI group: physical functioning (PF) (26.5 vs 87; p value <0.0001), role limitations due to physical (RP) (57.8 vs 93.6; p value <0.0001), bodily pain (BP) (60.5 vs 90.7; p value, 0.0001), general health (GH) (49.5 vs 76.6; p value <0.0001), vitality (VT) (51.2 vs 71.3; p value <0.0001), social functioning (SF) (68.9 vs 91.2; p value <0.0001), role limitations due to emotional problems (RE) (71.2 vs 91.5; p value 0.003) and mental health (MH) (62.9 vs 79; p value <0.0001). Concerning PCS and MCS scores, SCI patients reported significantly lower scores than control group (p value <0.0001).

CONCLUSION

Participants with SCI reported reduced QoL in comparison with normal individuals.

Contextualizing the lived experience of quality of life for persons with spinal cord injury: A mixed-methods application of the response shift model

Objective: The objective of this study was to gain greater insight into individuals' quality of life (QOL) definitions, appraisals, and adaptations following spinal cord injury (SCI). Design: A mixed-methods design, applying the Schwartz and Sprangers response shift (RS) model. RS is a cognitive process wherein, in response to a change in health status, individuals change internal standards, values, or conceptualization of QOL Setting: Community-dwelling participants who receive medical treatment at a major Midwestern medical system and nearby Veterans' Affairs hospital. Participants: A purposive sample of participants with SCI (N = 40) completed semi-structured interviews and accompanying quantitative measures. Interventions: Not applicable. Outcome Measures: Qualitative data were analyzed using content analysis to identify themes. Analysis of variance were performed to detect differences based on themes and QOL, well-being, and demographic and injury characteristics. Results: Four RS themes were identified, capturing the range of participant perceptions of QOL. The themes ranged from complete RS, indicating active engagement in maintaining QOL, to awareness and comparisons redefining QOL, to a relative lack of RS. Average QOL ratings differed as a function of response shift themes. PROMIS Global Health, Anxiety, and Depression also differed as a function of RS themes. Conclusion: The RS model contextualizes differences in QOL definitions, appraisals, and adaptations in a way standardized QOL measures alone do not.

Associations between health behaviour, secondary health conditions and quality of life in people with spinal cord injury

Background

The development of secondary health conditions (SHCs) after spinal cord injury (SCI) is common and can affect an individual’s emotional well-being, and his or her health-related quality of life (QOL). Little is known about relationships between performing health-benefiting behaviours and the presence (or absence) of SHCs and QOL, particularly in South Africa.

Objectives

This research study was conducted in order to determine the associations between health behaviour, SHCs and QOL in people with SCI (PWSCI).

Method

This cross-sectional study included 36 PWSCI discharged from a private rehabilitation facility in Pretoria, South Africa. The PWSCI completed questionnaires pertaining to lifestyle, independence, presence of SHCs, social support and QOL. Data were analysed using descriptive and inferential statistics such as correlation tests and chi-square test of independence (x²) using the SPSS v25. Moderate, moderately high and high correlations are reported (Pearson r ≥ 0.4). Results were significant if p < 0.05.

Results

Participation in health-benefiting behaviour was associated with increased QOL (r = 0.457, p < 0.01) and increased social support from family and friends (r = 0.425, p < 0.01), which was associated with increased QOL (r = 0.671, p < 0.001). Not participating in specific neuromusculoskeletal health behaviours was found to be associated with the overall presence of SHCs (r = -0.426, p < 0.01).

Conclusions

Participating in health-benefiting behaviour can reduce the development of SHCs and subsequently increase QOL in PWSCI. Health professionals must focus on minimising the development of SHCs by providing specific education on good health-benefiting behaviour.

Impact of Adaptive Sports Participation on Quality of Life

The health benefits of regular recreational physical activity are well known in reducing secondary health consequences of a sedentary lifestyle in the general population. However, individuals with physical disabilities participate less frequently in recreational activity compared with those without disabilities. Although evidence on the impact of recreational physical activity on quality of life in this population is in its infancy, regular recreational and sports activity participation has shown to have a positive association with improvements in quality of life, life satisfaction, community reintegration, mood, and employment in those with disabilities. Facilitators of participating in adaptive sports include a desire to improve social support, physical fitness, health, and fun. Unfortunately, those with disabilities face numerous barriers to participate in adaptive sports including accessibility, transportation, awareness, finances, and physical and cognitive impairments. Further studies are needed to investigate facilitators and barriers to participating in adaptive sports to capitalize on the physical and psychosocial benefits of regular recreational activity. The aim of this article is to review the available literature on the effects of adaptive sports participation on quality of life.
