Development and validation of a self-report version of the Spinal Cord Independence Measure (SCIM III)

Translation and validation of the Chinese self-report version of Spinal Cord Independence Measure (SCIM-SR): Rasch psychometric analysis and online application

Spinal Cord Independence Measure (SCIM) was an important functional outcome measure specifically designed for spinal cord injury (SCI) patients, with the self-reported version of SCIM (SCIM-SR) published in 2013. This study aims to translate the SCIM-SR into Chinese, and to investigate the validity of Chinese SCIM-SR among SCI patients. This Chinese version of SCIM-SR was translated into Chinese in a standardized approach, and then filled out by a sample of patients with SCI (n = 205) within 3 days after admission. Validity of Chinese SCIM-SR was then analyzed using Rasch analysis and principal component analysis. The subscale Selfcare and subscale Mobility showed good fit to the Rasch model, with no significance found in Chi-square test results for item-trait interaction, using Bonferroni adjustment for the significant level (χ2 =18.125, P = 0.111; χ2 =33.629, P = 0.006). Mean fit residual for items and persons of each subscale were within ± 2.5. The model fit of the subscale of Respiration and Sphincter Management was not satisfactory even after deleting one item and merging two items with local dependence. However, Kaiser-Meyer-Olkin test was > 0.50 in total score and all the subscales of Chinese SCIM-SR, and P < 0.05 in the Bartlett's test. There was no differential item functioning for gender, time post injury, age, and etiology in any of the three subscales. An online version of Chinese SCIM-SR was also developed. It is concluded that the SCIM-SR in Chinese is valid for application in individuals with SCI. SCIM-SR is considered as an important tool for self-reporting functional status from SCI individuals' perspective.

Functional balance assessment for predicting future recurrent falls in non-ambulatory individuals with spinal cord injury: a prospective pilot study

BACKGROUND

Functional assessments easy to administer within the clinic to identify non-ambulatory individuals with spinal cord injury at risk of recurrent falls are needed.

PURPOSE

To examine the ability of functional balance and transfer quality to predict recurrent falls.

METHODS

This 6-month prospective study examined remote assessments of transfer quality using the Transfer Assessment Instrument and functional sitting balance with the Function in Sitting Test and the Trunk Control Test. Then, participants prospectively monitored their falls for 6-month using fall diaries. Frequency of falls was categorized as infrequent fallers (≤2 falls) and recurrent fallers (>2 falls). A multivariable logistic regression analysis was conducted. A Receiver Operating Characteristic curve was performed to determine the area under the curve, the sensitivity, and the specificity of the model.

RESULTS

Eighteen non-ambulatory individuals (mean age = 44 ± 16 years, mean time since injury = 7.8 ± 32.6 years) participated in the study. Poor balance (lower Function in Sitting Test score) was associated with higher odds of future recurrent falls (Odds Ratio = 0.70, 95% CI, 0.48 to 1.00, p = 0.05), area under the receiving operating curve = 0.87, sensitivity = 88%, and specificity = 70%.

CONCLUSIONS

A comprehensive sitting balance assessment that includes the static, proactive, and reactive components of balance with the integration of sensorial functions as evaluated within the Function in Sitting Test may be useful for predicting recurrent falls among non-ambulatory individuals with spinal cord injury. Replication of the findings in a larger sample is warranted.

Gender differences in patient experience among persons with spinal cord injury: A comparison across 22 countries

BACKGROUND

Due to the majority of males within the population of persons with spinal cord injuries (SCI), a male-oriented perception of persons with SCI might affect care provision in the way of prioritizing male needs.

OBJECTIVE

The objective of this cross-sectional study is to describe the patient experience of persons with SCI by gender.

METHODS

This study was based on the International Spinal Cord Injury Survey with 12,588 participants from 22 countries. An interval-based patient experience score was attained by partial credit model. Regression analysis was used in exploring the association between patient experience and gender.

RESULTS

Participants reported very good and good patient experience. Respectful treatment was reported by 78 % of participants; clear explanations by 75 %; involvement in decision-making by 71 %; satisfaction with services by 62 %. The average patient experience score was equal among males and females (average: 64, range: 0-100), with the highest score in participants from the USA (78) and the lowest - in Morocco (44). Patient experience score was not associated with gender. Females had lower odds of reporting better decision-making involvement, yet higher odds of better satisfaction. Older participants, with higher household income and better self-rated health, had lower odds of being satisfied.

CONCLUSION

The majority of persons with SCI rated their experience as good or very good. Females were more likely to report higher satisfaction with services and lower involvement in decision-making. For other patient experience categories and the overall patient experience score, no association with gender was found.

Complex lived experiences and hidden disability after spinal cord injury: a latent profile analysis of the Australian arm of the International Spinal Cord Injury (Aus-InSCI) Community Survey

PURPOSE

To identify and examine subgroups of people with spinal cord injury (SCI) with different patterns of lived experience, and examine hidden impairments and disability among functionally independent and ambulant people.

MATERIALS AND METHODS

Latent profile analysis of population-based data from the Australian arm of the International Spinal Cord Injury (InSCI) Community survey (n = 1579).

RESULTS

Latent subgroups reflected levels of functional independence and extent of problems with health, activity/participation, environmental barriers, and self-efficacy. Quality of life (QoL), psychological profiles, and activity/participation were often as good or better in participants who reported lower (vs. higher) functional independence alongside comparable burden of health problems and environmental barriers. QoL, mental health, and vitality reflected self-efficacy and problem burdens more closely than functional independence. Ambulant participants reported a substantial burden of underlying, potentially hidden impairments, with QoL and mental health similar to wheelchair users.

CONCLUSION

Hidden disability among more independent and/or ambulant people with SCI can affect well-being substantially. Early and ongoing access to support, rehabilitation, and SCI specialist services is important irrespective of cause, type, severity of injury, and level of functional independence. Improved access to SCI expertise and equity of care would help to improve early recognition and management of hidden disability.

Psychosocial factors associated with athlete adaptation to spinal cord injury: a systematic review

PURPOSE

To review existing research on psychosocial factors associated with athlete adaptation to acquired spinal cord injury (SCI).

METHODS

A systematic review was conducted in February 2023. MEDLINE (Pubmed), PsycINFO, and SPORTDiscus databases were used, and peer-reviewed academic journal entries fully retrievable from the researcher's institution library or online were considered for inclusion. Publications were identified according to predetermined eligibility criteria, and 18 publications were included in the review.

RESULTS

The results identified many psychosocial factors associated with adaptation to acquired SCI, including self-identity, emotions, coping strategies, sport involvement, social support, narratives, pain, participation, activity, self-efficacy, and sociability.

CONCLUSIONS

This review highlights the need for innovative methodologies and diverse perspectives and sampling in future investigations. Rehabilitation and sport and performance psychology practitioners working with athletes with acquired SCI are encouraged to gain a better understanding of the narratives framing and constraining athletes' life stories and rehabilitation experiences and consider using strategies such as narrative ambushing (Frank, 2010) to help athletes develop new ways of thinking about acquired SCI. Rehabilitation practitioners are also encouraged to discuss and facilitate opportunities to get involved in adaptive sports for athletes with acquired SCI as part of their rehabilitation plan.

Perceived Relational Empathy and Resilience in People with Spinal Cord Injury at the End of Acute Care: A Cross-Sectional Study

In patients with spinal cord injury (SCI), patient-reported outcomes (PROMs) and experience of care measures (PREMs) are extremely relevant for the prognosis. However, there is a paucity of research on these topics. We conducted a cross-sectional study to investigate the relationships between these patient outcomes and other demographic and clinical variables in adult SCI patients discharged from the intensive care unit of an Italian tertiary rehabilitation hospital. We administered the Consultation and Relational Empathy (CARE) for perceived relational empathy, the Spinal Cord Independence Measure III self-report (SCIM-SR) for functional autonomy, the Numeric Rating Scale (NRS) for pain, and the Connor-Davidson Resilience Scale (CD-RISC-10) for resilience. Study participants consisted of 148 adults with SCI; 82.4% were male, with a mean age of 49.9 years (SD = 16.6). The lesion was traumatic in 82.4% and complete in 74.3% of cases. The median length of hospital stays was 35 days (interquartile range-IQR = 23-60). Perceived relational empathy was positively associated with resilience (r = 0.229, p = 0.005) and negatively associated with the length of the stay and lesion completeness. Resilience had a weak negative association with pain (r = -0.173, p = 0.035) and was unrelated to other variables. Clinicians should consider the routine assessment of PREMs and PROMs in order to personalize post-discharge therapeutic plans and identify appropriate measures to ensure continuity of care.

Feasibility and validity of the push-up test for synchronous and asynchronous strength tele-assessment in spinal cord injury individuals with paraplegia

OBJECTIVES

This study aimed to determine whether the synchronous and asynchronous push-up tele-assessment in individuals with spinal cord injury (SCI) is feasible and valid and to identify the relationship between the participants' self-reported asynchronous strength tele-assessment and asynchronous push-up tele-assessment.

STUDY DESIGN

Cross-sectional study.

METHODS

Thirty-three men and women with SCI were included in this study. The participants were assessed using the one-maximum repetition test (1RM), the maximum repetitions with 60% of 1RM (MRT) of the bench press exercise, and synchronous and asynchronous push-up tele-assessment. The videos and the total repetitions performed were recorded. The primary outcomes were 1RM, MRT, synchronous push-up tele-assessment and asynchronous volume loads, and the participants' self-reported asynchronous strength tele-assessment volume load.

RESULTS

The synchronous push-up tele-assessment and asynchronous volume loads presented significant correlations with 1RM (0.73 and 0.45, p < 0.001, respectively) and MRT volume loads (0.87 and 0.66, p < 0.001, respectively). The asynchronous push-up tele-assessment presented significant correlations with the synchronous version (intraclass correlation coefficient, ICC = 0.86; 95% CI: 0.72-0.93, p < 0.001) and participants' self-reported asynchronous strength tele-assessment volume loads (ICC = 0.88; 95% CI: 0.75-0.94, p < 0.001). The difference between the synchronous push-up tele-assessment and asynchronous volume load means was 254.9 kg, and the interval around the differences was 1856.1 kg. The difference between asynchronous push-up tele-assessment and participants' self-reported asynchronous strength tele-assessment means was -239.4 kg, and the interval around these was 1884.1 kg.

CONCLUSION

The synchronous push-up tele-assessment is a feasible and valid way to assess the maximum resistance strength of individuals with SCI. Although the asynchronous push-up tele-assessment demonstrated excellent and significant correlations with the synchronous push-up tele-assessment and participants' self-reported asynchronous strength tele-assessment, the test repetitions and the volume loads were underestimated by 15.5% (synchronous push-up tele-assessment vs. asynchronous) and overestimated by 17.3% (asynchronous push-up tele-assessment vs. participants' self-reported asynchronous strength tele-assessment), and the effect sizes ranged from 0.19-0.38. The authors suggest emphasizing the criteria of repetition validity to reduce test error.

Correlates of physical activity in ambulatory people with spinal cord injury during the first year after inpatient rehabilitation

STUDY DESIGN

Longitudinal cohort study.

OBJECTIVES

Examine the longitudinal association between mobility and level of physical activity (PA) and explore which other factors are also associated with level of PA in ambulatory people with Spinal Cord Injury (SCI) during the first-year post-inpatient rehabilitation.

SETTING

Three SCI-specialized rehabilitation centers and the Dutch community.

METHODS

Forty-seven adults with recent SCI and ambulatory function were included. All had motor incomplete lesions, 49% had tetraplegia, and the mean age was 55 ± 13 years. Duration of accelerometry-based all-day PA and self-reported level of mobility, exertion of walking, pain, fatigue, depressive mood symptoms, fear of falling, exercise self-efficacy, and attitude toward PA were measured just before discharge from inpatient rehabilitation and 6 and 12 months after discharge. All data were longitudinally analyzed using generalized estimating equations analyses. Models were corrected for age, lesion level, and time since injury.

RESULTS

Mobility was longitudinally associated with level of PA (beta: 4.5, P < 0.001, R2: 41%). In addition, lower levels of exertion of walking (beta: -5.6, P < 0.001), fear of falling (beta: -34.1, P < 0.001), and higher levels of exercise self-efficacy (beta: 2.3, P = 0.038) were associated with higher levels of PA. Exertion of walking and fear of falling were associated with level of PA independent of mobility.

CONCLUSIONS

Mobility, exertion of walking, fear of falling, and exercise self-efficacy seem to be correlates of level of PA in ambulatory people with SCI during the first year after inpatient rehabilitation. Targeting these factors using an interdisciplinary approach may enhance levels of PA in this population.

Comparing surgeries to restore upper extremity function in tetraplegia: Impact on function during the perioperative period

CONTEXT/OBJECTIVE

To assess short-term changes in health outcomes in people with cervical-level spinal cord injury (SCI) who underwent upper extremity (UE) reconstruction via either novel nerve transfer (NT) or traditional tendon transfer (TT) surgery with individuals who did not undergo UE surgical reconstruction.

DESIGN

Prospective, comparative cohort pilot study.

PARTICIPANTS

34 participants with cervical SCI met the following inclusion criteria: age 18 or older, greater than 6 months post-injury, and mid-cervical level SCI American Spinal Injury Association Impairment Scale (AIS) A, B or C.

SETTING

Two tertiary academic hospitals and their affiliated veterans' hospitals.

METHODS

Health outcomes were assessed using two previously validated measures, the Spinal Cord Independence Measure (SCIM) and Short-Form Health Survey (SF-36). Demographic, surgical, and survey data were collected at the initial evaluation and one month postoperatively/post-baseline.

RESULTS

34 participants with cervical SCI were recruited across three cohorts: no surgery (n = 16), NT (n = 10), and TT (n = 8). The TT group had a decline in SCIM and SF-36 scores whereas the NT and no surgery groups experienced little change in independence or health status in the immediate perioperative period.

CONCLUSIONS

Surgeons and rehabilitation providers must recognize differences in the perioperative needs of people with cervical SCI who chose to have restorative UE surgery. Future work should focus on further investigation of health outcomes, change in function, and improving preoperative counseling and cross-disciplinary management.

Change in mobility independence over 5 years for persons with chronic spinal cord injury

OBJECTIVES

To evaluate change in mobility independence (MI) in community dwelling persons with spinal cord injury (SCI).

PARTICIPANTS

Community Survey.

DESIGN

Cohort study. Rasch analysis was applied to the mobility subscale of the Spinal Cord Independence Measure - Self-Report data from years 2012 to 2017, resulting in a Rasch Mobility Independence Score (RMIS). We employed multilevel modeling to examine RMIS and its change over 5 years, adjusting for demographics and SCI severity; random forest regression was applied to determine the impact of modifiable factors (e.g. environmental factors, home-support) on its change.

RESULTS

The analysis included 728 participants. The majority (≈85%) of participants demonstrated little or no change in RMIS from 2012 to 2017; however, a smaller proportion (15%) showed considerably large change of more than 10 on the 100-point scale. A mixed-effects model with random slopes and intercepts described the dataset very well (conditional R2 of 0.95) in terms of demographics and SCI severity. Age was the main predictor of change in RMIS. Considering SCI severity, change in RMIS was related to age for the subgroup with paraplegia, and to time since injury for the subgroup with tetraplegia. No impact of modifiable factors was found.

CONCLUSION

RMIS in persons with SCI changes over a period of 5 years, especially in elder patients with paraplegia and persons with incomplete tetraplegia with more than 15 years of time since injury. During routine follow-up change in mobility independence should be assessed in order to timely intervene and prevent mobility loss and participation limitations.

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.

Association Between the Availability of Mobility Assistive Products and Participation Outcomes in Individuals With Spinal Cord Injury in Switzerland

Objectives

This study investigated the association between the reported availability of mobility assistive products and the perceived frequency, restriction, and satisfaction of participation in individuals with spinal cord injury in Switzerland.

Methods

This study was based on a cross-sectional analysis based on questionnaire data collected from the Swiss SCI Cohort Study community survey in 2012 (N = 492). The availability of 12 mobility assistive products were analyzed as the main predictor variable. The outcomes of interest were the frequency, restriction, and satisfaction of participation scales as measured by the 32-item Utrecht Scale for Evaluation of Rehabilitation-Participation (USER-P). The association between availability of mobility assistive products and participation was investigated using linear regressions analyses. All mobility assistive products were ranked in terms of relevance to improve participation by means of an importance performance plot.

Results

The availability of a sports wheelchair or a hand bike were both significant in reducing the restriction to participation. Having an adapted car increased the frequency of participation.

Conclusion

The availability of a sports wheelchair or a hand bike was significantly associated with less restriction in participation. With an unmet need of up to 36%, the known health benefits of regular physical activity and thereby cost-saving potential for the health care system, external support in the acquiring or use of these sports-related mobility assistive products could be an easy target for intervention.

Factors influencing employment among people with spinal cord injury in South Africa

PURPOSE

The unemployment rate post spinal cord injury (SCI) in South Africa is high with limited knowledge of environmental factors outside the health services, especially in an unevenly developed resource setting like South Africa, affecting the employment rate in people with SCI. Our purpose was to investigate factors associated with employment in people with SCI in South Africa.

METHODS

Two hundred persons with SCI participated in a cross-sectional survey design. This study formed part of the International Spinal Cord Injury Community Survey. Subsections of the questionnaire responses were used as explanatory variables to predict employment after SCI using logistic regression analysis.

RESULTS

The response rate of the study was 54%. Of the 200 participants included, 61% reported being employed before SCI onset whereas only 25% reported being engaged in paid work at the time of this study. The logistic regression model showed not requiring physical assistance in the home environment (p = 0.016), the number of education years before SCI (p = 0.007), household income (p < 0.001), having worked before SCI onset (p = 0.041), and environmental factors (p = 0.029) to be factors associated with employment after SCI.

CONCLUSION

The finding suggests multiple factors influence the employment rate, advocating for interdisciplinary rehabilitation approaches and social development interventions to address meaningful occupations in persons with SCI in South Africa.Implications for rehabilitationRehabilitation programs should be adapted and tailored to enhance physical independence.Public policies regarding environmental factors such as access to reliable transport, assistive devices, and public places for wheelchair users are important and could potentially support individuals with spinal cord injury (SCI) becoming employed/re-employed.For successful social/community/civic reintegration for individuals with SCI an intersectional collaboration (i.e., between policymakers, health professionals, and the labor market) needs to be considered to improve the employment opportunities post-SCI.

Early and intensive motor training to enhance neurological recovery in people with spinal cord injury: trial protocol

STUDY DESIGN

Protocol for a multi-centre randomised controlled trial (the SCI-MT trial).

OBJECTIVES

To determine whether 10 weeks of intensive motor training enhances neurological recovery in people with recent spinal cord injury (SCI).

SETTING

Fifteen spinal injury units in Australia, Scotland, England, Italy, Netherlands, Norway, and Belgium.

METHODS

A pragmatic randomised controlled trial will be undertaken. Two hundred and twenty people with recent SCI (onset in the preceding 10 weeks, American Spinal Injuries Association Impairment Scale (AIS) A lesion with motor function more than three levels below the motor level on one or both sides, or an AIS C or D lesion) will be randomised to receive either usual care plus intensive motor training (12 h of motor training per week for 10 weeks) or usual care alone. The primary outcome is neurological recovery at 10 weeks, measured with the Total Motor Score from the International Standards for Neurological Classification of SCI. Secondary outcomes include global measures of motor function, ability to walk, quality of life, participants' perceptions about ability to perform self-selected goals, length of hospital stay and participants' impressions of therapeutic benefit at 10 weeks and 6 months. A cost-effectiveness study and process evaluation will be run alongside the trial. The first participant was randomised in June 2021 and the trial is due for completion in 2025.

CONCLUSIONS

The findings of the SCI-MT Trial will guide recommendations about the type and dose of inpatient therapy that optimises neurological recovery in people with SCI.

Health System's Role in Facilitating Health Service Access among Persons with Spinal Cord Injury across 22 Countries

(1) Background: Despite efforts to improve access to health services, between- and within-country access inequalities remain, especially for individuals with complex disabling conditions like spinal cord injury (SCI). Persons with SCI require regular multidisciplinary follow-up care yet experience more access barriers than the general population. This study examines health system characteristics associated with access among persons with SCI across 22 countries. (2) Methods: Study data are from the International Spinal Cord Injury Survey with 12,588 participants with SCI across 22 countries. Cluster analysis was used to identify service access clusters based on reported access restrictions. The association between service access and health system characteristics (health workforce, infrastructure density, health expenditure) was determined by means of classification and regression trees. (3) Results: Unmet needs were reported by 17% of participants: lowest (10%) in Japan, Spain, and Switzerland (cluster 1) and highest (62%) in Morocco (cluster 8). The country of residence was the most important factor in facilitating access. Those reporting access restrictions were more likely to live in Morocco, to be in the lowest income decile, with multiple comorbidities (Secondary Conditions Scale (SCI-SCS) score > 29) and low functioning status (Spinal Cord Independence Measure score < 53). Those less likely to report access restriction tended to reside in all other countries except Brazil, China, Malaysia, Morocco, Poland, South Africa, and South Korea and have fewer comorbidities (SCI-SCS < 23). (4) Conclusions: The country of residence was the most important factor in facilitating health service access. Following the country of residence, higher income and better health were the most important facilitators of service access. Health service availability and affordability were reported as the most frequent health access barriers.

Skin self-management of community-dwelling patients with spinal cord injury: A cross-sectional study

BACKGROUND

community-acquired pressure injury is one of the most common and troublesome complications of discharged patients with spinal cord injury. Previous studies have shown that pressure injury can not only increase the financial burden and care burden of patients, but also seriously affect their quality of life.

AIM

To evaluate the skin self-management of community-dwelling patients with spinal cord injury and to explore the related independent influencing factors.

METHODS

This was a cross-sectional survey study. A convenience sample of 110 community-dwelling patients with spinal cord injury recruited from three rehabilitation centers in Guangzhou and Chengdu in China completed the survey from September 2020 to June 2021. They were asked about their demographic data, skin self-management, knowledge about skin self-management, attitude to skin self-management, self-efficacy, and functional independence. Univariate analysis and multiple linear regression were performed to isolate the most important relationships.

RESULTS

The skin self-management of community-dwelling patients with spinal cord injury was relatively low, and they also performed poorly in the three categories of: skin check, preventing pressure ulcer, and preventing wounds. Skin self-management was found to be most often associated with level of knowledge about skin self-management, higher reimbursement and self-efficacy.

CONCLUSION

Community-dwelling patients with spinal cord injury with lower level of knowledge about skin self-management, with lower self-efficacy, and those with higher reimbursement have worse skin self-management.

Standardized administration and scoring guidelines for the Spinal Cord Independence Measure Version 3.0 (SCIM-III)

STUDY DESIGN

Qualitative studies.

OBJECTIVE

To develop clear and specific administration and scoring procedures for the Spinal Cord Independence Measure Version 3.0 as a performance-based and interview assessment.

SETTING

Research lab.

METHODS

Modified Delphi Technique survey methods were used in this study. Previously developed SCIM-III administration and scoring procedures for performance-based and interview versions were presented to clinicians experienced in SCI and SCIM-III using the Qualtrix (Qualtrics, Provo, UT) online survey platform. Summary and descriptive statistics were used to assess the percent agreement survey responses.

RESULTS

Three survey rounds were necessary to achieve 80% agreement or above for the performance-based version. Two survey rounds were necessary to achieve 80% agreement or above on the interview version.

CONCLUSIONS

This study describes the development of standardized administration and scoring procedures for the self-care and mobility sub-scales of the SCIM-III as a performance-based and interview version.

Australian arm of the International Spinal Cord Injury (Aus-InSCI) community survey: 1. population-based design, methodology and cohort profile

STUDY DESIGN

Cross-sectional survey.

OBJECTIVES

To describe design and methods of Australian arm of International Spinal Cord Injury (Aus-InSCI) community survey, reporting on participation rates, potential non-response bias and cohort characteristics.

SETTING

Survey of community-dwelling people with SCI at least 12 months post-injury, recruited between March 2018 and January 2019, from state-wide SCI services, a government insurance agency and not-for-profit consumer organisations across four Australian states.

METHODS

The Aus-InSCI survey combined data for people with SCI from nine custodians, using secure data-linkage processes, to create a population-based, anonymised dataset. The Aus-InSCI questionnaire comprised 193 questions. Eligibility, response status and participation rates were calculated. Descriptive statistics depict participant characteristics. Logistic regression models were developed for probability of participation, and inverse probability weights generated to assess potential non-response bias.

RESULTS

1579 adults with SCI were recruited, a cooperation rate of 29.4%. Participants were predominantly male (73%), with 50% married. Mean age was 57 years (range 19-94) and average time post-injury 17 years (range 1-73). Paraplegia (61%) and incomplete lesions (68%) were most common. Males were more likely than females to have traumatic injuries (p < 0.0001) and complete lesions (p = 0.0002), and younger age-groups were more likely to have traumatic injuries and tetraplegia (p < 0.0001). Potential non-response bias evaluated using selected outcomes was found to be negligible in the Aus-InSCI cohort.

CONCLUSIONS

The Aus-InSCI survey made efforts to maximise coverage, avoid recruitment bias and address non-response bias. The distributed, linked and coded (re-identifiable at each custodian level) 'virtual quasi-registry' data model supports systematic cross-sectional and longitudinal research.

Cardiac autonomic modulation in response to postural transition during a virtual reality task in individuals with spinal cord injury: A cross-sectional study

PURPOSE

The postural transition from sitting to standing is a moment of dysautonomic occurrence in individuals with Spinal Cord Injury (SCI). Different tools can be used to minimize this event, such as virtual reality. Thus, we aimed to analyze cardiac autonomic modulation in individuals with SCI during postural transition from the sitting to orthostatism position using a cognitive virtual reality (VR) task.

METHODS

Individuals with and without SCI were positioned on the Easy Stand® device, sitting at rest, at 0° considering the angle between the seat and the floor, elevation at 45°, and orthostatism at 90°, for 5 minutes in each position. Heart rate variability (HRV) measures of sympathovagal balance were collected (heart rate receiver: Polar V800). The groups were subdivided into two groups, one that performed VR as an intervention during the postural angle changes and another group that did not perform VR.

RESULTS

We evaluated 76 individuals, 40 with a medical diagnosis of SCI and 36 who composed the able-bodied control group without SCI, matched by age and sex. The HRV results showed that the SCI group who performed the task in VR demonstrated no significant difference in parasympathetic activation and global variability between the sitting versus 90° positions. There was better sympathovagal balance in SCI and able-bodied control groups who performed the VR task between the sitting versus 90° positions.

CONCLUSION

The use of a VR task seems to contribute to better sympathovagal balance, with the potential to reduce dysautonomia during postural changes.

Influence of Sociodemographic Factors, Health Conditions, and Activity on Participation in People With Spinal Cord Injury in South Korea

OBJECTIVE

To verify the causal relationship between sociodemographic factors, health conditions, and activities that influence the participation of people with spinal cord injury (SCI) using International Spinal Cord Injury (InSCI) Survey data and to investigate the moderation effects of environmental restrictions and health care system concerns.

DESIGN

Cross-sectional community survey and structural equation model.

SETTING

SCI databases of the Korea National Rehabilitation Center and Korea Spinal Cord Injury Association.

PARTICIPANTS

Community-dwelling adults (N=890) with SCI.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The InSCI questionnaire domains included sociodemographic factors, health conditions, activity, participation, environmental restrictions, and health system concerns. Sociodemographic factors included age, education, and income. Health conditions included bowel dysfunction, respiratory problems, and pain, among others. Activity included "daily routine" and "using hands," among others. Participation included "interacting with people" and "intimate relationships," among others. Environmental restrictions included "public places" and "negative attitudes," among others. Health care system concerns included "nursing care" and "experience of being treated," among others.

RESULTS

The hypothesis that health conditions would have a significant effect on activity was supported because 51% of the total variance in activity factors was explained by health condition factors. The hypothesis that activity would have a significant effect on participation was also supported because 63.4% of total variance in participation factors was explained by activity factors. The moderation effect tests supported the hypotheses that health conditions, activity, and participation would differ depending on the extent of environmental restrictions as well as the extent of health system concerns.

CONCLUSIONS

When formulating policies and recommendations to promote the participation of people with SCI living in the South Korean community, the influence of environmental restrictions and health systems as well as the causal influence of health conditions and activity should be considered.

Leisure-Time Physical Activity in People With Spinal Cord Injury-Predictors of Exercise Guideline Adherence

Objectives: This study described leisure-time physical activity (LTPA) for people in Australia with spinal cord injury (SCI) and whether certain sociodemographic and psychosocial variables might be associated with LTPA uptake and guidelines adherence. Methods: The Physical Activity Scale for Individuals with a Physical Disability was used to measure the intensity and volume of LTPA of 1,579 individuals with SCI. Summary statistics were calculated for LTPA guidelines adherence. Analyses included regression modelling. Results: Of the 1,579 participants, 58% performed LTPA and 13% adhered to recommended guidelines for weekly LTPA. There was an association with being an "exerciser" based on the time since injury (OR = 1.02 [95% 1.01-1.03]), a traumatic injury (OR = 1.53 [95% CI 1.13-2.08]) and a higher self-rating of health (OR = 1.10 [95% CI 0.95-1.27]). Where LTPA guidelines were met, adherence was most related to a traumatic injury (OR = 1.75 [95% CI 1.02-3.02]) and being unemployed (OR = 1.53 [95% CI 1.03-2.25]). Conclusion: Of those who performed LTPA with SCI, one in four met population-specific LTPA guidelines. Sociodemographic variables were moderately associated with being an "exerciser" or LTPA "guideline-adherent."

Factors Related to Engagement in Employment After Spinal Cord Injury in Australia: A Cross-sectional Study

OBJECTIVE

To explore the association between sociodemographic, health, functional independence, and environmental variables with engagement in paid work for people with spinal cord injury (SCI).

DESIGN

Self-reported, cross-sectional Australian data from a large international SCI survey.

SETTING

Community-based.

PARTICIPANTS

1189 working-age people with SCI (18-67 years) or aged >67 years and engaged in paid employment. Respondents were community based and at least 1 year after injury.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Employment and work integration variables. Bayesian penalized regression was used to determine associations between 23 predictor variables and engagement in paid work.

RESULTS

Most participants (87%) were employed pre-injury, with 39% in paid employment at the time of the survey. Participants who attained a master's/doctoral degree (odds ratio [OR]=3.01; 95% credible interval [CrI], 1.63, 5.44) and those married (OR=1.68; 95% CrI, 1.13, 2.49) were more likely to be engaged in paid work. Women (OR=0.55; 95% CrI, 0.37, 0.81), people receiving a disability pension (OR=0.17; 95% CrI, 0.13, 0.24), and older participants (OR=0.75; 95% CrI, 0.63, 0.90) were less likely to be in paid work. Working participants identified hardships including problems completing their work (60%) and accessing the workplace (32%), as well as unmet needs relating to assistive devices required for completing their work (50%).

CONCLUSIONS

Findings from the current study can assist in directing resources to subgroups within the SCI population who need greater assistance or intervention related to employment outcomes, including through vocational rehabilitation services/programs. Unmet needs and workplace issues expressed by employed individuals identify gaps in work integration and satisfaction that could affect employment sustainability that need to be addressed.

Quantifying Donor Deficits Following Nerve Transfer Surgery in Tetraplegia

PURPOSE

Nerve transfer (NT) surgery can improve function in people with cervical spinal cord injury (SCI). However, the impact of donor nerve deficits remains unclear. The purpose of this study was to quantify donor deficits experienced by individuals with cervical SCI following NT.

METHODS

This prospective single-arm, comparative study included people with SCI undergoing upper extremity NTs. Myometry was used to assess muscle strength at baseline and follow-up. The Spinal Cord Independence Measure was used to measure the ability to perform activities of daily living.

RESULTS

Ten individuals underwent 20 NTs to restore elbow extension (donor, posterior deltoid; n = 2), hand opening (donor, supinator; n = 7), and hand closing (donor, brachialis; n = 11). Shoulder abduction strength decreased (-5.6% at early and -4.5% late follow-up) in the elbow extension NT. Wrist extension strength decreased at early (-46.9% ± 30.3) and increased by late (76.4% ± 154.0) follow-up in the hand opening NT. No statistically significant change in elbow flexion strength was noted in the hand closing NT. Spinal Cord Independence Measure scores did not change significantly between baseline and early postoperative follow-up; they improved at late follow-up.

CONCLUSIONS

Use of expendable donor nerves with redundant function to perform NT surgery has relatively little impact on strength or capacity to perform activities of daily living, even in the unique and highly vulnerable SCI population. Early, temporary loss in wrist extension strength can be seen after the supinator to posterior interosseous nerve transfer. This study offers quantitative data about possible diminution of donor function after NT, enabling hand surgeons to better counsel individuals contemplating upper extremity reconstruction.

Socioeconomic Status, the Countries’ Socioeconomic Development and Mental Health: Observational Evidence for Persons with Spinal Cord Injury from 22 Countries

Objectives: Evidence on social inequalities in mental health of persons with physical impairments is limited. We therefore investigate associations of individual-level socioeconomic status (SES) and the country-level socioeconomic development (SED) with mental health in persons with spinal cord injury (SCI).

Methods: We analyzed data from 12,588 participants of the International SCI Community Survey from 22 countries. To investigate individual-level inequalities, SES indicators (education, income, financial hardship, subjective status) were regressed on the SF-36 mental health index (MHI-5), stratified by countries. Country-level inequalities were analyzed with empirical Bayes estimates of random intercepts derived from linear mixed-models adjusting for individual-level SES.

Results: Financial hardship and subjective status consistently predicted individual-level mental health inequalities. Country-level SED was inconsistently related to mental health when adjusting for individual-level SES. It however appeared that higher SED was associated with better mental health within higher-resourced countries.

Conclusion: Reducing impoverishment and marginalization may present valuable strategies to reduce mental health inequalities in SCI populations. Investigations of country-level determinants of mental health in persons with SCI should consider influences beyond country-level SED, such as cultural factors.

Feasibility of gabapentin as an intervention for neurorecovery after an acute spinal cord injury: Protocol

Introduction

This protocol is describing the first ever prospective, mock-efficacy, dose exploration trial design testing the feasibility of administering gabapentin in the acute setting as an intervention for neurorecovery. Gabapentin is an FDA-approved medication for treating seizures and postherpetic neuralgia and is used broadly off-label for neuropathic pain management for many conditions, including spinal cord injury. Emerging data suggests that when given early after spinal cord injury onset and in low-medium doses, gabapentin may have properties that promote recovery of neurological function. The objective of this trial is to assess the feasibility of conducting an efficacy trial in which gabapentin is started early after injury, is restricted in its dose, and is not used for pain management.

Methods and analysis

Forty-two people aged 18 years or older with any level and any severity of spinal cord injury induced by a trauma will be enrolled, randomized, and have the first dose of study medication by 120 h post-injury onset. Participants will be randomly assigned to one of three groups: 600, 1,800 mg/day gabapentin, or placebo. Study medication will be given for a 90-day duration. Blinded assessments will be obtained at 7 days post-injury (baseline), 30 days post-injury (interim), after the 90-day treatment duration/approximately 3 months post-injury (end of treatment), and at 6 months post-injury (end of study). The key analysis parameters will evaluate feasibility of recruitment of target population, delivery of drug treatment protocol, maintenance of blinding, and retention of participants.

Discussion

Outputs from this trial will inform research and clinical practice on the effects of manipulating gabapentin for non-pain management purposes in the acute setting and will guide the development of a properly powered efficacy trial of gabapentin as an intervention for neurorecovery in spinal cord injury.

Ethics and dissemination

The study was approved by the MetroHealth Institutional Review Board (IRB21-00609) and registered at clinicaltrials.gov prior to enrolling any participants. Dissemination will include peer-reviewed publications, presentations at professional conferences and in the community, and through other healthcare and public venues.

Investigating Dynamics of the Spinal Cord Injury Adjustment Model: Mediation Model Analysis

Spinal cord injury (SCI) is a severe neurological injury that results in damage to multiple bodily systems. SCI rehabilitation requires a significant focus on improving adjustment to the injury. This paper presents a detailed description of the Spinal Cord Injury Adjustment Model (SCIAM), which clarifies how individuals adjust to SCI and contends that adjustment to SCI is a multifactorial process involving non-linear dynamic adaptation over time. Evidence supporting SCIAM is also discussed. Mediation analyses were conducted to test the mediator dynamics proposed by the model. The analyses tested the relationship between two moderators (self-care and secondary health conditions), mediators (two self-efficacy items and appraisal of quality of life or QoL), and positive versus negative vitality/mental health as outcomes. Results showed that higher self-efficacy and perceived QoL was related to greater independence in self-care and reduced negative impacts of secondary health conditions. This study supported the mediation role of self-efficacy and other appraisals such as perceived QoL in enhancing self-care and buffering the negative impact of health challenges. In conclusion, it is important to employ a holistic model such as SCIAM to conceptualise and increase understanding of the process of adjustment following a severe neurological injury such as SCI.

The Impact of an Evidence-Informed Spinal Cord Injury Activities of Daily Living Education Manual (SADL-eM): Protocol for a Randomized Controlled Trial

BACKGROUND

Spinal cord injury (SCI) is a catastrophic injury associated with functional loss and life-threatening complications. Many people with SCI in the Gaza Strip of Palestine are discharged from inpatient rehabilitation to the community while still lacking many daily life skills. This randomized controlled trial (RCT) seeks to test the impact of the Spinal Cord Injury Activities of Daily Living Education Manual (SADL-eM)-an evidence-based occupational therapy patient educational intervention-on rehabilitation outcomes.

OBJECTIVE

The proposed trial aims to evaluate the SADL-eM intervention compared with standard treatment among people with SCI.

METHODS

This is a parallel RCT with two study arms: intervention and control. A total of 90 patients treated in inpatient rehabilitation settings will be randomly allocated to two study groups. Both groups will receive standard care. The intervention group will also use the SADL-eM with their treating occupational therapist during rehabilitation. The SADL-eM is a comprehensive activities of daily living (ADL) educational tool that was codeveloped with people with SCI and stakeholders across Gaza. The self-report version of the Spinal Cord Independence Measure will be used on admission (ie, baseline measure) and after 6 weeks as the primary outcome measure. Secondary outcomes include the third version of the Spinal Cord Independence Measure, the Private Religiousness Practices Scale, the Organizational Religiousness Short-Form, additional ADL domains covered by the education manual, and adherence to the intervention. The effect of the intervention will be determined using repeated-measures analysis of variance.

RESULTS

This study will be conducted from April 2021 through December 2022, with results expected to be available in January 2023.

CONCLUSIONS

If the SADL-eM is demonstrated as clinically effective, this will have significant implications for occupational therapy interventions in low- and middle-income countries.

Soft robotics and functional electrical stimulation advances for restoring hand function in people with SCI: a narrative review, clinical guidelines and future directions

Background

Recovery of hand function is crucial for the independence of people with spinal cord injury (SCI). Wearable devices based on soft robotics (SR) or functional electrical stimulation (FES) have been employed to assist the recovery of hand function both during activities of daily living (ADLs) and during therapy. However, the implementation of these wearable devices has not been compiled in a review focusing on the functional outcomes they can activate/elicit/stimulate/potentiate. This narrative review aims at providing a guide both for engineers to help in the development of new technologies and for clinicians to serve as clinical guidelines based on the available technology in order to assist and/or recover hand function in people with SCI.

Methods

A literature search was performed in Scopus, Pubmed and IEEE Xplore for articles involving SR devices or FES systems designed for hand therapy or assistance, published since 2010. Only studies that reported functional outcomes from individuals with SCI were selected. The final collections of both groups (SR and FES) were analysed based on the technical aspects and reported functional outcomes.

Results

A total of 37 out of 1101 articles were selected, 12 regarding SR and 25 involving FES devices. Most studies were limited to research prototypes, designed either for assistance or therapy. From an engineering perspective, technological improvements for home-based use such as portability, donning/doffing and the time spent with calibration were identified. From the clinician point of view, the most suitable technical features (e.g., user intent detection) and assessment tools should be determined according to the particular patient condition. A wide range of functional assessment tests were adopted, moreover, most studies used non-standardized tests.

Conclusion

SR and FES wearable devices are promising technologies to support hand function recovery in subjects with SCI. Technical improvements in aspects such as the user intent detection, portability or calibration as well as consistent assessment of functional outcomes were the main identified limitations. These limitations seem to be be preventing the translation into clinical practice of these technological devices created in the laboratory.

Reliability of the Nepali Version of the Spinal Cord Independence Measure Self-Report

A self-report measure is considered a practical alternative tool for longitudinal monitoring and for community models of disability. Spinal Cord Independence Measure Self-Report (SCIM-SR) was developed to measure the functional independence of the spinal cord injury (SCI) population. For the application of this questionnaire in Nepali setting, the cross-cultural adaptation and reliability of the Nepali version of the SCIM-SR were also warranted. The aim of the study was to cross-culturally adapt the Nepali version of the SCIM-SR and determine its reliability. The English version of the SCIM-SR was translated into the Nepali language with cross-cultural adaptations following the Beaton guidelines. A total of 45 community-dwelling individuals with SCI administered the Nepali version of the SCIM-SR two times, with an interval of one week. The intraclass correlation coefficient (ICC) and Cronbach's alpha (α) were used to assess the test-retest reliability and internal consistency, respectively. Cross-cultural equivalence was achieved between the English version and the Nepali version of the SCIM-SR. The test-retest reliability was excellent, with ICCs for the total score 0.968 (95% confidence interval 0.941–0.982), self-care subscale 0.964 (0.934–0.980), respiration and sphincter management subscale 0.941 (0.893–0.968), and mobility subscale 0.966 (0.938–0.981). The internal consistency reached an acceptable range for the total score and most of the subscales except for those of respiration and sphincter management. Cronbach's α coefficients for the total score, self-care subscale, respiration and sphincter management subscale, and mobility subscale were 0.801, 0.959, 0.506, and 0.838, respectively. The Nepali version of the SCIM-SR was cross-culturally adapted and can be used as a reliable self-report instrument to assess functional independence among the community-dwelling SCI population in Nepal.

Australian arm of the International Spinal Cord Injury (Aus-InSCI) Community Survey: 2. Understanding the lived experience in people with spinal cord injury

STUDY DESIGN

Cross-sectional survey.

OBJECTIVES

To identify common problems across key domains of functioning, health and wellbeing, as well as evaluate self-reported quality of life (QoL) by people with SCI, examining differences by age, gender, injury characteristics and level of mobility.

SETTING

Data from four state-wide SCI clinical services, one government insurance agency and three not-for-profit consumer organisations.

METHODS

Participants were 18 years or over with SCI and at least 12 months post-injury, recruited between Mar'18 and Jan'19. The Aus-InSCI questionnaire comprised 193 questions, including socio-demographics, SCI characteristics, body functions and structures, activities and participation, environmental and personal factors, and appraisal of health and well-being. General linear model was used to examine differences in functioning and QoL.

RESULTS

Participants (mean age 57 years, range 19-94 years) with tetraplegia and/or complete injuries had more health problems, activity/participation problems and environmental barriers. However, self-rated overall QoL did not differ for injury level or completeness. Participants with more recent injuries exhibited lower independence levels, more mental health problems and poorer satisfaction with self and their living conditions. Major activity/participation problems related to intimate relationships and accessing public transportation. Less than half of the working age population were engaged in paid work. The top two environmental barriers frequently related to accessing public places or homes and unfavourable climatic conditions.

CONCLUSIONS

This large, comprehensive community survey draws a detailed picture of the lived experience of people with SCI in Australia, identifying priority needs, gaps in services and barriers to achieving a full and satisfying life.

Rehabilitation of a young girl with acute transverse myelitis and prolonged lower motor neuron features: a longitudinal case report over 12 months

Background

This report describes an effective rehabilitation programme for a 13-year-old girl, diagnosed with acute transverse myelitis, as an example of best clinical practice.

Case description

Miss A was admitted to the National Institute of Neurosciences and Hospital in Dhaka, where she was diagnosed with acute transverse myelitis, in September 2018. She was discharged and referred for intensive rehabilitation over 3 months as an outpatient at the Centre for the Rehabilitation of the Paralysed in Bangladesh. The therapy team conducted a baseline assessment before starting treatment, which included the following outcome measures: the International Standards for Neurological Classification of Spinal Cord Injury Scale; Spinal Cord Independence Measure; and the Spinal Cord Injury Functional Ambulation Inventory. After 3 months, Miss A was discharged home to continue with a home exercise programme supported by her parents. Outcome measurements were repeated at 3-, 6- and 12-month time points.

Results

Miss A regained muscle power in her legs and normal sensation in S4/5 dermatomes, in addition to regaining voluntary anal muscle contraction. Her mobility and transfers improved so that she was able to transfer in and out of her wheelchair independently and use two elbow crutches to walk short distances outdoors.

Conclusions

This report shows that it is possible for a child who had been severely disabled by acute transverse myelitis to make substantial physical improvements up to 12 months after diagnosis when provided with effective rehabilitation. It also identifies that rehabilitation can provide multiple benefits and value for the individual patient, family, community and society.

Análise da independência funcional em indivíduos com lesão da medula espinal

Resumo Introdução A lesão da medula espinal (LME) muda radicalmente a vida da pessoa devido às alterações na dinâmica corporal, levando à incapacidades e redução da funcionalidade. Objetivo Analisar a independência funcional de indivíduos com LME e comparar os grupos. Métodos Indivíduos com LME foram entrevistados sobre sua independência funcional por meio da versão brasileira do Spinal Cord Independence Measure - Self-Reported Version (brSCIM-SR) e posteriormente seus respectivos domínios e subdomínios foram comparados entre os grupos diagnósticos, tempo de lesão e gênero. Resultados A amostra foi composta por 50 indivíduos com idade de 40,92 ± 13,93 anos, prevalecendo homens e diagnóstico de paraplegia. Na maioria dos domínios do brSCIM-SR todos os entrevistados atingiram boa independência no autocuidado, na respiração e controle esfincteriano e no total do brSCIM-SR, exceto na mobilidade. Na paraplegia, as LMEs crônicas e ambos os sexos alcançaram excelente independência na maioria dos subdomínios e no total do instrumento. Valores significantemente baixos foram encontrados na tetraplegia e nas LMEs recentes no subdomínio autocuidado. Na maioria dos subdomínios, a tetraplegia atingiu valores significativamente inferiores. Nos subdomínios da respiração e controle esfincteriano, os participantes eram independentes na função respiração, mas nas tetraplegias apresentaram significativa depen-dência nas transferências para o vaso sanitário. Na mobilidade houve grande dependência nos itens subir e descer escadas e transferir-se do chão para a cadeira de rodas. Conclusão Os indivíduos com LME demonstra-ram boa independência funcional, com pior desempenho na tetraplegia e lesões recentes, mas a mobilidade apresentou parcial dependência nos participantes.

Functional independence analysis in persons with spinal cord injury

Abstract Introduction Spinal cord injury (SCI) radically changes a person’s life because of alterations in body dynamics, leading to disabilities and reduced functionality. Objective To analyze the functional independence of individuals with spinal cord injury and compare the groups. Methods Individuals with SCI were interviewed about their functional independence using the Brazilian version of the Spinal Cord Independence Measure - Self-Reported Version (brSCIM-SR) and later their respective domains and subdomains were compared between diagnostic groups, time since injury and sex. Results The sample consisted of fifty individuals aged 40.92 ± 13.93 years, predominantly men and diagnosed with paraplegia. In most brSCIM-SR domains, all respondents achieved good independence in self-care, respiration and sphincter management, and in the total brSCIM-SR, except for mobility. In paraplegia, chronic SCIs and both sexes achieved excellent independence in most subdomains and in the total. Significantly low values were found for tetraplegia and recent SCI in the self-care subdomain. In most subdomains, tetraplegia reached significantly lower values. In the subdomains of respiration and sphincter management, the participants were independent in the breathing function, but in tetraplegia, they showed significant dependence on transfer to the toilet. In terms of mobility, there was great dependence on the items going up and down stairs and transfer from the floor to the wheelchair. Conclusion The brSCIM-SR measures the degree of functionality, allowing health professionals and the patient to quantify and locate the items that indicate their deficits or gains during the rehabilitation process. Here, individuals with SCI showed good functional independence, with worse performance in the tetraplegia and recent injury groups: however, mobility showed partial dependence in the participants.

Pathways to loneliness: a mediation analysis investigating the social gradient of loneliness in persons with disabilities in Switzerland

Background

The experience of loneliness can have drastic consequences for health and quality of life. Given that loneliness is highly prevalent in persons with physical disabilities and that loneliness more profoundly affects persons of low socioeconomic status, more evidence is required in order to understand the mechanisms determining loneliness in this population. The objective of this study is therefore to investigate the potential pathways through which socioeconomic status influences loneliness in persons with spinal cord injury.

Methods

Mediation analysis utilising structural equation models and bias corrected and accelerated confidence intervals were used in order to test the mediation effects of health status, functioning, participation, social support and self-efficacy on the association between socioeconomic status and loneliness in persons with spinal cord injury. A latent construct was created for socioeconomic status with the indicators education, household income, financial hardship, subjective social status and engagement in paid work.

Results

This study found evidence to support the mediating role of psychosocial resources and of secondary health conditions in the association between socioeconomic status and loneliness. The study demonstrated robust associations between socioeconomic status and all potential mediators, whereby higher socioeconomic status was associated with better health, participation and psychosocial resources, however, not all potential mediators were associated with loneliness. The serial mediation model explained the interplay between socioeconomic status, mediators on different levels, and loneliness. For example, emotional support and self-efficacy were both positively associated with fewer restrictions to participation (0.08 (CI: 0.05, 0.12); 0.29 (CI: 0.24, 0.36) respectively), and fewer restrictions to participation were found to be a result of improved functional independence and fewer secondary health conditions (0.23 (CI: 0.15, 0.39); − 0.29 (CI: − 0.36, − 0.20) respectively).

Conclusions

Our findings highlight the vulnerability of persons with low socioeconomic status to loneliness in persons with spinal cord injury and identified potential mediating factors, such as health, functioning, participation and psychosocial resources, in the association between socioeconomic status and loneliness. This population-based evidence suggests potential targets of interventions on the pathway to loneliness, through which socioeconomic status influences loneliness. The complexity of the model shows the need for comprehensive interprofessional rehabilitation to identify and support people with lower socioeconomic status and concomitant risk factors for loneliness.

Preliminary evaluation of the reliability and validity of the 3D printed Toronto Rehabilitation Institute-Hand Function Test in individuals with spinal cord injury

OBJECTIVE

The study objectives were to evaluate the inter-rater and intra-rater reliability; and criterion and construct validity of the 3D printed Toronto Rehabilitation Institute -Hand Function Test (3D TRI-HFT) in individuals with spinal cord injury (SCI).

DESIGN

Observational study.

SETTING

Inpatient Rehabilitation Hospital.

PARTICIPANTS

Four individuals with subacute and three individuals with chronic SCI.

INTERVENTIONS

Reliability and validity of the 3D TRI-HFT was assessed within two interventional studies.

OUTCOME MEASURES

Participants performed the 3D TRI-HFT, Graded Redefined Assessment of Strength, Sensibility and Prehension (GRASSP), Functional Independence Measure (FIM) and the Spinal Cord Independence Measure (SCIM) at baseline, after 20 and 40 sessions of therapy and at six month follow-up from baseline. 3D TRI-HFT assessments were graded at the time of performance and re-graded from the video recordings for purpose of reliability testing. Validity testing was done by comparing the scores on 3D TRI-HFT with the scores on the GRASSP, and the FIM and SCIM self care sub-scores.

RESULTS

The 3D TRI-HFT had high intra-rater and inter-rater reliability in sub-acute and chronic SCI with ICC values exceeding 0.99. Moderate to strong correlations were found between 3D TRI-HFT object manipulation scores and the FIM and SCIM self care sub-scores, with r values in the range of 0.7-0.8. Strong correlations were found between the various components of GRASSP and the 3D TRI-HFT, with r values exceeding 0.9.

CONCLUSIONS

The 3D TRI-HFT is a reliable and valid measure to assess unilateral hand gross motor function in individuals with SCI.

[Germany-wide, Web-based ParaReg Registry for Lifelong Monitoring of People with Spinal Cord Injury: Data Model, Ethico-legal Prerequisites and Technical Implementation]

OBJECTIVE

In Germany, treatment paths for patients with acute spinal cord injury (SCI) differ considerably depending on intrinsic, disease-specific and extrinsic factors. Which of these factors are associated with improved outcome with fewer subsequent complications and inpatient re-admissions is not clear. The German-wide, patient-centered, web-based ParaReg registry will be implemented to improve the long-term quality of patient care and the planning of treatment paths with increased cost-effectiveness.

METHODS

In the 2017-18 conceptualization phase, the data model of the registry was developed in an iterative process of the ParaReg steering committee together with the extended DMGP board and patient representatives. In ParaReg, routine social and medical data as well as internationally established neurological, functional and participation scores will be documented. The assignment of a unique patient ID allows a lifelong, cross-center documentation of inpatient stays in one of the 27 SCI centers organized in the German-speaking Medical Society for SCI (DMGP). The ParaReg data protection concept and patient information/consent are based on the Open Source Registry for Rare Diseases (OSSE) which were extended by GDPR-relevant aspects.

RESULTS

In the realization phase, which started in 2019, the information technology infrastructure was implemented according to the clinical ID management module of the Technology and Methods Platform for Networked Medical Research (TMF). In parallel, the legal and ethical prerequisites for registry operation under the patronage of the DMGP were created. Recommendations of the working group data protection of the TMF were integrated into ParaReg's data protection concept. Based on the feedback from the alpha test phase with documentation of the hospitalization data of 40 patients, the ergonomics of the electronic case report forms were improved in particular for data entry on mobile devices.

CONCLUSION

After completion of the monocentric alpha test phase, the multicenter data acquisition was started in 5 DMGP-SCI centers. The sustainability of ParaReg is ensured by the structural and financial support of the DMGP after expiry of the funding by the German Federal Ministry of Education and Research (BMBF).

Who is at Risk of Loneliness? A Cross-sectional Recursive Partitioning Approach in a Population-based Cohort of Persons With Spinal Cord Injury

OBJECTIVE

To develop a more thorough understanding of the risk factors for loneliness in persons with a physical impairment, using a population-based sample of persons with spinal cord injury (SCI), based on regression modeling and a recursive partitioning approach.

DESIGN

Cross-sectional, observational cohort.

SETTING

Community, Switzerland.

PARTICIPANTS

Community-dwelling persons with spinal cord injury (N=1283) 16 years or older.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Loneliness was assessed using a modified version of the UCLA Three-Item Loneliness Scale.

RESULTS

Those with the most disadvantaged socioeconomic characteristics in terms of education, income, subjective social position, employment status, and financial hardship demonstrated the highest risk for loneliness. Of the sociodemographic characteristics, only age had an association with loneliness, whereby persons aged 31-45 had the highest propensity for experiencing loneliness. We also saw that those with higher lesion levels and less functional independence were associated with higher levels of loneliness. In conditional inference tree analysis subjective social position, financial hardship, and functional independence had the highest discriminative power, with nationality and living arrangement having a less important role.

CONCLUSIONS

Our findings highlight the vulnerability of persons with SCI with unfavorable socioeconomic status to loneliness. Furthermore, our findings show that persons who are more constrained because of functional limitations may face restrictions to social participation and therefore be at a higher risk of loneliness. This population-based evidence contributes to the better targeting of services aimed at alleviating loneliness for persons with a lower socioeconomic position and those with more functional limitations in everyday life.

Functional independence in the Finnish spinal cord injury population

Study design

A cross-sectional survey of the Finnish population with spinal cord injury (FinSCI database).

Objectives

To describe the functional independence of the population with spinal cord injury (SCI) in Finland and to identify how generic and lesion characteristics affect their functional independence.

Setting

The participants were recruited from the registers of three SCI outpatient clinics responsible for lifelong follow-up and care for people with SCI in Finland.

Methods

The data were retrieved from FinSCI (n = 1772). The response rate was 50% (n = 884). The Spinal Cord Independence Measure-Self Report (SCIM-SR) was used. The data were analyzed with univariate testing, factor analyses, and multiple linear regression models.

Results

The median (percentiles 25; 75) SCIM-SR total score was 76.0 (58.8; 89.0), and the score was 18.0 (13.0; 20:0) for the self-care sub-scale, 33.0 (25.0; 39.0) for the respiration and sphincter management sub-scale and 29.0 (16.0; 36.8) for the mobility sub-scale. The higher the neurological level in groups AIS A, B, and C, the lower the functional ability. Group AIS D at any injury level had the highest level of functional ability. Age and the number of years since injury negatively influenced the SCIM-SR scores for every sub-scale.

Conclusion

Based on the International Spinal Cord Injury Core Data Set, the severity of SCI can differentiate persons with SCI according to their functional ability. The results suggest that SCI affects individuals’ health more than ageing alone does, thereby reducing the functional ability and independence of persons with SCI over time.

Handgrip Strength Cutoff Points for Functional Independence and Wheelchair Ability in Men With Spinal Cord Injury

Objectives

To determine optimal handgrip strength (HGS) cutoff points for greater functional independence and wheelchair skills in men with spinal cord injury (SCI), and to establish predictive equations for functional independence and wheelchair ability in men with SCI, based on demographic characteristics, HGS, and functionality.

Methods

In this cross-sectional study conducted at a rehabilitation hospital, 54 men with SCI were recruited and stratified into high and low paraplegia groups. All participants performed a maximum HGS test to determine cutoff points for the Spinal Cord Independence Measure (SCIM-III) and Adapted Manual Wheelchair Circuit (AMWC). The primary outcomes were the SCIM-III, AMWC, and HGS. Demographic characteristics obtained from participants' electronic medical records were the secondary outcomes, used as predictor variables of functional independence.

Results

The SCIM-III scale, performance score, and 3-minute overground wheeling test presented significant regression equations (R = 0.45, R = 0.69, and R = 0.72). The HGS showed a cutoff point of 102.5 kilogram force (kgf) to achieve a score of 70 on the SCIM-III and a 3-minute overground wheeling distance of 270 m. The HGS cutoff point to obtain a performance score of 23.7 seconds was 93.0 kgf.

Conclusion

The HGS was a significant predictor for the SCIM-III score, AMWC performance score, and 3-minute overground wheeling test. Three significant predictive equations were established based on HGS. The cutoff points could be adopted as parameters for optimal functional independence and wheelchair skills.

Long term outcome of functional independence and quality of life after traumatic SCI in Germany

STUDY DESIGN

Multicenter observational study.

OBJECTIVE

To describe the long-term outcome of functional independence and quality of life (QoL) for individuals with traumatic and ischemic SCI beyond the first year after injury.

SETTING

A multicenter study in Germany.

METHODS

Participants of the European multicenter study about spinal cord injury (EMSCI) of three German SCI centers were included and followed over time by the German spinal cord injury cohort study (GerSCI). Individuals' most recent spinal cord independence measure (SCIM) scores assessed by a clinician were followed up by a self-report (SCIM-SR) and correlated to selected items of the WHO short survey of quality of life (WHO-QoL-BREF).

RESULTS

Data for 359 individuals were obtained. The average time passed the last clinical SCIM examination was 81.47 (SD 51.70) months. In total, 187 of the 359 received questionnaires contained a completely evaluable SCIM-SR. SCIM scores remained stable with the exception of reported management of bladder and bowel resulting in a slight decrease of SCIM-SR of -2.45 points (SD 16.81). SCIM-SR scores showed a significant correlation with the selected items of the WHO-QoL-BREF (p < 0.01) with moderate to strong influence.

CONCLUSION

SCIM score stability over time suggests a successful transfer of acquired independence skills obtained during primary rehabilitation into the community setting paralleled by positively related QoL measurements but bladder and bowel management may need special attention.

Adaptation and validation of the Japanese version of the Spinal Cord Independence Measure (SCIM III) self-report

STUDY DESIGN

Psychometric study, cross-sectional validation study.

OBJECTIVES

To adapt and validate the Japanese version of the Spinal Cord Independence Measure self-report (SCIM-SR).

SETTING

A spinal cord injury (SCI) rehabilitation facility in Japan.

METHODS

We adapted the SCIM-SR for the Japanese population by translating and validating the questionnaire in accordance with the international guidelines. Following this, we analyzed 100 inpatients with SCI. We evaluated their independence using the Japanese SCIM-SR, and compared the data with those assessed using the SCIM III by trained ward nurses.

RESULTS

Spearman's rank correlation coefficients were 0.95 for the total score, 0.89 for self-care, 0.83 for respiration and sphincter management, and 0.89 for mobility subscores. The Bland-Altman analysis revealed no significant proportional bias (-0.02; 95% CI [-0.07, 0.06]), but a significant fixed bias (2; 95% CI [0.5, 3.5]). We did not identify any specific factor that affected the differences between SCIM III and SCIM-SR scores.

CONCLUSIONS

Our study validated the Japanese version of SCIM-SR as a tool for the evaluation of the independence of persons with SCI, which could substitute SCIM III and help facilitate a deeper understanding of activities of daily living among patients with SCI.

Translation and validation of the Chinese version of the Spinal Cord Independence Measure (SCIM III) Self-Report

STUDY DESIGN

A cross-sectional psychometric study.

OBJECTIVE

To translate, culturally adapt and validate the Chinese version of the Spinal Cord Independence Measure III-Self Report (SCIM-SR).

SETTING

Four rehabilitation centers in Guangzhou, Chengdu, and Shiyan, China.

METHODS

Translation and cultural adaptation of the Chinese version of the SCIM-SR was conducted according to Brislin guidelines. A total of 147 spinal cord injury patients self-rated their functional independence using translated instrument. The psychometric properties of content validity, criterion-related validity, internal consistency reliability, and test-retest reliability were examined.

RESULTS

The content validity index of the new scale was 0.99. The intraclass correlation coefficient between the total SCIM-SR and SCIM III scores was 0.935, and the coefficients for its three subscales were 0.899, 0.760, and 0.942. Bland-Altman analysis showed that the mean difference between the total SCIM-SR and SCIM III scores was 2.35 (95% confidence interval -0.58 to 5.28), and differences for the three subscales were 0.75 (-0.51-2.01), 1.30 (-0.63-3.23), and 0.30 (-0.80-1.40). The Cronbach's α coefficients for the total scale, the self-care subscale, and the mobility subscale were 0.908, 0.913, and 0.895, respectively. The α for the respiration and sphincter management subscale was 0.581. Test-retest reliability after 2 weeks yielded a Spearman coefficient for the total scale of and subscale values all above 0.73.

CONCLUSIONS

Our results indicate acceptable validity and reliability of the Chinese version of SCIM-SR. It may facilitate long-term evaluations of independence in Chinese spinal cord injury patients in the community and at home.

Labor market participation of individuals with spinal cord injury living in Switzerland: determinants of between-person differences and counterfactual evaluation of their instrumental value for policy

STUDY DESIGN

Longitudinal, population-based survey.

OBJECTIVE

To examine determinants of between-person differences in labor market participation of individuals with spinal cord injury (SCI) living in Switzerland and their potential importance for policy.

SETTING

Community.

METHODS

Longitudinal information on labor market participation (i.e., paid work or not) was obtained from 1198 and 1035 individuals of working-age participating in the 2012 and 2017 SwiSCI community survey, respectively. Determinants of between-person variation in labor market participation were examined using mixed effects logistic regression, controlling for within-person variation. Employment rates were predicted using counterfactual data for modifiable determinants.

RESULTS

The employment rate was 56% for the 2012 and 61% for the 2017 survey. Labor market participation was affected mostly by static (sex, nationality, SCI severity), temporal (age), dynamic (education level, functional independence, chronic pain), and policy-related (general pension, disability pension level) determinants. Counterfactual (what-if) predictions indicated the highest improvement of employment rates for strategies that increase functional independence (up to 6% increase), foster education (5%), reduce chronic pain (2%), or promote a shift to partial disability pensions (15%).

CONCLUSIONS

Between-person variation in labor market participation of persons with SCI is influenced by various temporal, static, dynamic, and policy-related determinants. Our results suggest that policy strategies aimed at enhancing the employment rate of the Swiss SCI population may particularly invest in programs promoting functional independence, education, and partial pension levels that are more adequate for ensuring sustainable employment.

Development of Reaching, Grasping & Manipulation indicators to advance the quality of spinal cord injury rehabilitation: SCI-High Project

OBJECTIVE

To describe the development of structure, process, and outcome indicators aimed to advance the quality of Reaching, Grasping & Manipulation (RG&M) rehabilitation for Canadians living with spinal cord injury or disease (SCI/D).

METHOD

Upper extremity rehabilitation experts developed a framework of indicators for evaluation of RG&M rehabilitation quality. A systematic search of the literature identified potential upper extremity indicators that influence RG&M outcomes. A Driver diagram summarized factors influencing upper extremity outcomes to inform the selection of structure and process indicators. Psychometric properties, clinical utility, and feasibility of potential upper extremity measures were considered when selecting outcome indicators.

RESULTS

The selected structure indicator is the number of occupational and physical therapists with specialized certification, education, training and/or work experience in upper extremity therapy related to RG&M at a given SCI/D rehabilitation center. The process indicator is the total hours of upper extremity therapies related to RG&M and the proportion of this time allocated to neurorestorative therapy for each individual with tetraplegia receiving therapy. The outcome indicators are the Graded Redefined Assessment of Strength, Sensation and Prehension (GRASSP) strength and Spinal Cord Independence Measure III (SCIM III) Self-Care subscores implemented at rehabilitation admission and discharge, and SCIM III Self-Care subscore only at 18 months post-admission.

CONCLUSION

The selected indicators align with current practice, will direct the timing of routine assessments, and enhance the volume and quality of RG&M therapy delivered, with the aim to ultimately increase the proportion of individuals with tetraplegia achieving improved upper extremity function by 18 months post-rehabilitation.

Change in environmental barriers experienced over a 5-year period by people living with spinal cord injury in Switzerland: a prospective cohort study

STUDY DESIGN

Cohort study with two measurement occasions.

OBJECTIVES

To investigate change in environmental barriers experienced by people living with spinal cord injury (SCI) over a 5-year period.

SETTING

Community, Switzerland.

METHODS

Data were from the Swiss spinal cord injury (SwiSCI) survey. Main outcome measure was the Nottwil Environmental Factors Inventory-Short Form. Random-effects Poisson regression featuring between-within estimation was used to examine predictors of the number of environmental barriers and of its change over time.

RESULTS

One thousand five hundred and forty-nine persons participated in Survey 2012 and 1530 participated in Survey 2017; 761 participated in both surveys. In both surveys most participants reported at least three barriers. Leading issues were unfavorable climate, inaccessibility of buildings and public spaces, and lack of or insufficiently adapted means of transportation. Reporting of barriers related to climate, finances, and state services declined over time. Between subjects, having more health problems, lesser physical independence, poorer mental health, and a lower household income were related to a higher number of barriers experienced. Within subjects, improvements in income, physical independence, and mental health over time were related to a reduction in barriers.

CONCLUSIONS

Inaccessibility of buildings and places and problems with transportation remained major barriers over a 5-year period and should be priorities of Swiss disability policy. People with reduced mental and physical health, and those with lower income are vulnerable groups deserving specific attention. Policies targeting income and life-long rehabilitation targeting health promotion and maintenance may be suitable means to reduce the experience of environmental barriers.

Psychosocial resources and chronic pain in individuals with spinal cord injury: evidence from the second Swiss national community survey

STUDY DESIGN

Cross-sectional.

OBJECTIVE

To investigate the associations of a set of psychosocial resources with pain and pain-related factors in individuals with spinal cord injury (SCI) and chronic pain.

SETTING

Community, Switzerland.

METHODS

Data from 1,064 individuals with chronic pain who participated in the second community survey of the Swiss Spinal Cord Injury Cohort Study (Survey 2017) were analyzed. Multiple linear regression modeling was performed to test the hypotheses that higher levels of psychosocial resources (self-efficacy, self-esteem, purpose in life, optimism, hope, social support, sense of belonging) are negatively associated with pain intensity, pain interference and depressive symptoms.

RESULTS

Higher self-esteem, optimism and hope were related to less pain interference and all psychosocial resources under study were negatively associated with depressive symptoms in final models. However, neither of the psychosocial resources was related to pain intensity when models were adjusted for pain interference and depressive symptoms.

CONCLUSIONS

These findings strengthen the evidence that psychosocial resources can have an impact on pain interference and depressive symptoms as pain-related factors, and support the notion that psychosocial resources might be promising targets for pain interventions in individuals with SCI.

Describing Functioning in People Living With Spinal Cord Injury Across 22 Countries: A Graphical Modeling Approach

OBJECTIVE

To provide prevalence estimates for problems in functioning of community-dwelling persons with spinal cord injury (SCI) and to examine associations between various areas of functioning with the purpose of supporting countries in identifying targets for interventions.

DESIGN

Cross-sectional survey.

SETTING

Community, 22 countries including all World Health Organization regions.

PARTICIPANTS

Persons (N=12,591) with traumatic or nontraumatic SCI aged 18 years or older.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

We estimated the prevalence of problems in 53 areas of functioning from the Brief International Classification of Functioning, Disability and Health (ICF) core set for SCI, long-term context, or ICF rehabilitation set covering 4 domains: impairments in body functions, impairments in mental functions, independence in performing activities, and restrictions in participation. Associations between areas of functioning were identified and visualized using conditional independence graphs.

RESULTS

Participants had a median age of 52 years, 73% were male, and 63% had paraplegia. Feeling tired, bowel dysfunction, sexual functions, spasticity, pain, carrying out daily routine, doing housework, getting up off the floor from lying on the back, pushing open a heavy door, and standing unsupported had the highest prevalence of problems (>70%). Clustering of associations within the 4 functioning domains was found, with the highest numbers of associations within impairments in mental functions. For the whole International Spinal Cord Injury sample, areas with the highest numbers of associations were circulatory problems, transferring bed-wheelchair, and toileting, while for the World Health Organization European and Western Pacific regions, these were dressing upper body, transferring bed-wheelchair, handling stress, feeling downhearted and depressed, and feeling happy.

CONCLUSIONS

In each domain of functioning, high prevalence of problems and high connectivity of areas of functioning were identified. The understanding of problems and the identification of potential targets for intervention can inform decision makers at all levels of the health system aiming to improve the situation of people living with SCI.

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.
