Impact of Upper Limb Motor Recovery on Functional Independence After Traumatic Low Cervical Spinal Cord Injury

Cervical spinal cord injury (SCI) causes devastating loss of upper limb function and independence. Restoration of upper limb function can have a profound impact on independence and quality of life. In low-cervical SCI (level C5-C8), upper limb function can be restored via reinnervation strategies such as nerve transfer surgery. The translation of recovered upper limb motor function into functional independence in activities of daily living (ADLs), however, remains unknown in low cervical SCI (i.e., tetraplegia). The objective of this study was to evaluate the association of patterns in upper limb motor recovery with functional independence in ADLs. This will then inform prioritization of reinnervation strategies focused to maximize function in patients with tetraplegia. This retrospective study performed a secondary analysis of patients with low cervical (C5-C8) enrolled in the SCI Model Systems (SCIMS) database. Baseline neurological examinations and their association with functional independence in major ADLs-i.e., eating, bladder management, and transfers (bed/wheelchair/chair)-were evaluated. Motor functional recovery was defined as achieving motor strength, in modified research council (MRC) grade, of ≥ 3 /5 at one year from ≤ 2/5 at baseline. The association of motor function recovery with functional independence at one-year follow-up was compared in patients with recovered elbow flexion (C5), wrist extension (C6), elbow extension (C7), and finger flexion (C8). A multi-variable logistic regression analysis, adjusting for known factors influencing recovery after SCI, was performed to evaluate the impact of motor function at one year on a composite outcome of functional independence in major ADLs. Composite outcome was defined as functional independence measure score of 6 or higher (complete independence) in at least two domains among eating, bladder management, and transfers. Between 1992 and 2016, 1090 patients with low cervical SCI and complete neurological/functional measures were included. At baseline, 67% of patients had complete SCI and 33% had incomplete SCI. The majority of patients were dependent in eating, bladder management, and transfers. At one-year follow-up, the largest proportion of patients who recovered motor function in finger flexion (C8) and elbow extension (C7) gained independence in eating, bladder management, and transfers. In multi-variable analysis, patients who had recovered finger flexion (C8) or elbow extension (C7) had higher odds of gaining independence in a composite of major ADLs (odds ratio [OR] = 3.13 and OR = 2.87, respectively, p < 0.001). Age 60 years (OR = 0.44, p = 0.01), and complete SCI (OR = 0.43, p = 0.002) were associated with reduced odds of gaining independence in ADLs. After cervical SCI, finger flexion (C8) and elbow extension (C7) recovery translate into greater independence in eating, bladder management, and transfers. These results can be used to design individualized reinnervation plans to reanimate upper limb function and maximize independence in patients with low cervical SCI.

Comparison of One-Year Postinjury Mobility Outcomes Between Locomotor Training and Usual Care After Motor Incomplete Spinal Cord Injury

Objectives

To compare 1-year mobility outcomes of individuals with traumatic motor incomplete spinal cord injury (miSCI) who participated in standardized locomotor training (LT) within the first year of injury to those who did not.

Methods

This retrospective case-control analysis conducted with six US rehabilitation hospitals used SCI Model Systems (SCIMS) data comparing 1-year postinjury outcomes between individuals with miSCI who participated in standardized LT to those who received usual care (UC). Participants were matched on age, gender, injury year, mode of mobility, and rehabilitation center. The primary outcome is the FIM Total Motor score. Other outcomes include the FIM Transfer Index, FIM Stairs, and self-reported independence with household mobility, community mobility, and stairs.

Results

LT participants reported significantly better FIM Total Motor (difference = 2.812, 95% confidence interval [CI] = 5.896, 17.282) and FIM Transfer Index scores (difference = 0.958, 95% CI = 0.993, 4.866). No significant between-group differences were found for FIM Stairs (difference = 0.713, 95% CI = -0.104, 1.530) or self-reported household mobility (odds ratio [OR] = 5.065, CI = 1.435, 17.884), community mobility (OR = 2.933, 95% CI = 0.868, 9.910), and stairs (OR = 5.817, 95% CI = 1.424, 23.756) after controlling for multiple comparisons.

Conclusion

LT participants reported significantly greater improvements in primary and secondary measures of mobility and independence (FIM Total Motor score; FIM Transfer Index) compared to UC participants. Self-reported mobility outcomes were not significant between groups.

A Single Dermatome Clinical Prediction Rule for Independent Walking 1 Year After Spinal Cord Injury

OBJECTIVE

To derive and validate a simple, accurate CPR to predict future independent walking ability after SCI at the bedside that does not rely on motor scores and is predictive for those initially classified in the middle of the SCI severity spectrum.

DESIGN

Retrospective cohort study. Binary variables were derived, indicating degrees of sensation to evaluate predictive value of pinprick and light touch variables across dermatomes. The optimal single sensory modality and dermatome was used to derive our CPR, which was validated on an independent dataset.

SETTING

Analysis of SCI Model Systems dataset.

PARTICIPANTS

Individuals with traumatic SCI. The data of 3679 participants (N=3679) were included with 623 participants comprising the derivation dataset and 3056 comprising the validation dataset.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Self-reported ability to walk both indoors and outdoors.

RESULTS

Pinprick testing at S1 over lateral heels, within 31 days of SCI, accurately identified future independent walkers 1 year after SCI. Normal pinprick in both lateral heels provided good prognosis, any pinprick sensation in either lateral heel provided fair prognosis, and no sensation provided poor prognosis. This CPR performed satisfactorily in the middle SCI severity subgroup.

CONCLUSIONS

In this large multi-site study, we derived and validated a simple, accurate CPR using only pinprick sensory testing at lateral heels that predicts future independent walking after SCI.

Medical, dental, and optical care utilization among community-living people with spinal cord injury in the United States

CONTEXT/OBJECTIVE

Information about patterns of healthcare utilization for people living with spinal cord injury (SCI) is currently limited, and this is needed to understand independent community living after SCI. This study investigates self-reported healthcare utilization among community-living people with SCI and assesses disparities across demographic, socioeconomic, and injury-related subgroups.

DESIGN

Secondary analysis of cross-sectional survey data administered via telephone interview.

SETTING

6 SCI Model Systems centers in the United States (California, Colorado, New Jersey, New York, Ohio, and Pennsylvania).

PARTICIPANTS

Adults with chronic, traumatic SCI who were community-living for at least one year after the completion of an inpatient rehabilitation program (N = 617).

INTERVENTIONS

Not applicable.

OUTCOME MEASURES

Utilization of a usual source of 4 types of health care in the past 12 months: primary, SCI, dental, and optical.

RESULTS

84% of participants reported utilizing primary care in the past year. More than half reported utilizing SCI (54%) and dental (57%) care, and 36% reported utilizing optical care. There were no significant differences across key subgroups in the utilization of primary care. Participants who had been injured for 5 years or less and participants with greater educational attainment were more likely to report utilizing SCI care. Participants with higher household income levels were more likely to report using dental care. Female participants and older age groups were more likely to report using optical care.

CONCLUSION

Rates of healthcare utilization among people with SCI are below recommended rates and vary across demographic, socioeconomic, and injury-related subgroups. This information can inform future research to target barriers to using healthcare services among community-living people with SCI.

Residential Mobility and Reasons for Moving Among People Living With Spinal Cord Injury: Results of a Multisite Survey Study

Background

Residential mobility after spinal cord injury (SCI) has not been extensively examined despite a growing interest in investigating the relationship between neighborhood exposures and community living outcomes.

Objectives

This study explores residential mobility patterns, the annual move rate, and reasons for moving among a community-living sample of adults with SCI.

Methods

A survey was conducted with 690 people at six SCI Model Systems centers in the United States between July 2017 and October 2020. The outcomes included move status in the past 12 months, move distance, and the primary reason for moving. A sample from the 2019 American Community Survey (ACS) 5-year pooled estimates was obtained for comparative analysis. Descriptive statistics were used to summarize the distributions of the outcomes and differences between the samples.

Results

The annual move rate for adults with SCI was 16.4%, and most moves were within the same county (56.6%). Recent movers were more likely to be young adults, be newly injured, and have low socioeconomic status. Housing quality, accessibility, and family were more frequently reported motivations for moving compared to employment. Young adults more commonly moved for family and accessibility, whereas middle-aged adults more commonly moved for housing quality. No notable difference was observed in the annual move rate between the SCI and the general population samples.

Conclusion

These findings suggest an age-related pattern of residential relocation after SCI, which may be indicative an extended search for optimal living conditions that meet the housing and accessibility needs of this population.

Importance of Prospective Registries and Clinical Research Networks in the Evolution of Spinal Cord Injury Care

Only 100 years ago, traumatic spinal cord injury (SCI) was commonly lethal. Today, most people who sustain SCI survive with continual efforts to improve their quality of life and neurological outcomes. SCI epidemiology is changing as preventative interventions reduce injuries in younger individuals, and there is an increased incidence of incomplete injuries in aging populations. Early treatment has become more intensive with decompressive surgery and proactive interventions to improve spinal cord perfusion. Accurate data, including specialized outcome measures, are crucial to understanding the impact of epidemiological and treatment trends. Dedicated SCI clinical research and data networks and registries have been established in the United States, Canada, Europe, and several other countries. We review four registry networks: the North American Clinical Trials Network (NACTN) SCI Registry, the National Spinal Cord Injury Model Systems (SCIMS) Database, the Rick Hansen SCI Registry (RHSCIR), and the European Multi-Center Study about Spinal Cord Injury (EMSCI). We compare the registries' focuses, data platforms, advanced analytics use, and impacts. We also describe how registries' data can be combined with electronic health records (EHRs) or shared using federated analysis to protect registrants' identities. These registries have identified changes in epidemiology, recovery patterns, complication incidence, and the impact of practice changes such as early decompression. They've also revealed latent disease-modifying factors, helped develop clinical trial stratification models, and served as matched control groups in clinical trials. Advancing SCI clinical science for personalized medicine requires advanced analytical techniques, including machine learning, counterfactual analysis, and the creation of digital twins. Registries and other data sources help drive innovation in SCI clinical science.

Predicting Outdoor Walking 1 Year After Spinal Cord Injury: A Retrospective, Multisite External Validation Study

BACKGROUND AND PURPOSE

Predicting future outdoor walking ability after spinal cord injury (SCI) is important, as this is associated with community engagement and social participation. A clinical prediction rule (CPR) was derived for predicting outdoor walking 1 year after SCI. While promising, this CPR has not been validated, which is necessary to establish its clinical value. The objective of this study was to externally validate the CPR using a multisite dataset.

METHODS

This was a retrospective analysis of US SCI Model Systems data from 12 centers. L3 motor score, L5 motor score, and S1 sensory score were used as predictor variables. The dataset was split into testing and training datasets. The testing dataset was used as a holdout dataset to provide an unbiased estimate of prediction performance. The training dataset was used to determine the optimal CPR threshold through a "leave-one-site-out" cross-validation framework. The primary outcome was self-reported outdoor walking ability 1 year after SCI.

RESULTS

A total of 3721 participants' data were included. Using the optimal CPR threshold (CPR ≥ 33 threshold value), we were able to predict outdoor walking 1 year with high cross-validated accuracy and prediction performance. For the entire dataset, area under receiver operator characteristic curve was 0.900 (95% confidence interval: 0.890-0.910; P < 0.0001).

DISCUSSION AND CONCLUSIONS

The outdoor walking CPR has been externally validated. Future research should conduct a clinical outcomes and cost-benefit impact analysis for implementing this CPR. Our results support that clinicians may use this 3-variable CPR for prediction of future outdoor walking ability.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A411 ).

Comparison of veterans affairs and NIDILRR traumatic brain injury model systems participants with disorders of consciousness

OBJECTIVE

To characterize demographic, pre-injury, and outcome data within the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR) and Veterans Affairs (VA) Traumatic Brain Injury Model Systems (TBIMS) cohorts with severe traumatic brain injury (TBI) with no command-following ability at time of admission to acute rehabilitation.

DESIGN

Retrospective cohort.

SETTING

NIDILRR and VA TBI Model Systems (TBIMS) centers.

PARTICIPANTS

396 NIDILRR and 72 VA participants without command-following ability who experienced TBI with subsequent Disorder of Consciousness (DoC).

MAIN OUTCOME MEASURE

Pre-injury and injury characteristics, rehabilitation outcomes, and 1-year self-reported outcomes.

RESULTS

VA TBIMS cohort included individuals who were active duty or had military service before their injury. The VA cohort were more likely to be re-hospitalized at 1-year follow-up or residing in a long-term care or rehab setting. The NIDILRR TBIMS cohort had higher FIM and DRS scores at rehabilitation discharge, while the VA participants saw longer lengths of stay and higher numbers of "violent" injury types.

CONCLUSIONS

This study allows for a better understanding of the comparability between VA and NIDILRR DoC cohorts providing guidance on how veteran and civilian samples might be merged in future TBIMS studies to explore predictors of recovery from a DoC.

Derivation and Validation of a Clinical Prediction Rule for Upper Limb Functional Outcomes After Traumatic Cervical Spinal Cord Injury

IMPORTANCE

Traumatic cervical spinal cord injury (SCI) can result in debilitating paralysis. Following cervical SCI, accurate early prediction of upper limb recovery can serve an important role in guiding the appropriateness and timing of reconstructive therapies.

OBJECTIVE

To develop a clinical prediction rule to prognosticate upper limb functional recovery after cervical SCI.

DESIGN, SETTING, AND PARTICIPANTS

This prognostic study was a retrospective review of a longitudinal cohort study including patients enrolled in the National SCI model systems (SCIMS) database in US. Eligible patients were 15 years or older with tetraplegia (neurological level of injury C1-C8, American Spinal Cord Injury Association [ASIA] impairment scale [AIS] A-D), with early (within 1 month of SCI) and late (1-year follow-up) clinical examinations from 2011 to 2016. The data analysis was conducted from September 2021 to June 2022.

MAIN OUTCOMES AND MEASURES

The primary outcome was a composite of dependency in eating, bladder management, transfers, and locomotion domains of functional independence measure at 1-year follow-up. Each domain ranges from 1 to 7 with a lower score indicating greater functional dependence. Composite dependency was defined as a score of 4 or higher in at least 3 chosen domains. Multivariable logistic regression was used to predict the outcome based on early neurological variables. Discrimination was quantified using C statistics, and model performance was internally validated with bootstrapping and 10-fold cross-validation. The performance of the prediction score was compared with AIS grading. Data were split into derivation (2011-2014) and temporal-validation (2015-2016) cohorts.

RESULTS

Among 2373 patients with traumatic cervical SCI, 940 had complete 1-year outcome data (237 patients [25%] aged 60 years or older; 753 men [80%]). The primary outcome was present in 118 patients (13%), which included 92 men (78%), 83 (70%) patients who were younger than 60 years, and 73 (62%) patients experiencing AIS grade A SCI. The variables significantly associated with the outcome were age (age 60 years or older: OR, 2.31; 95% CI, 1.26-4.19), sex (men: OR, 0.60; 95% CI, 0.31-1.17), light-touch sensation at C5 (OR, 0.44; 95% CI, 0.44-1.01) and C8 (OR, 036; 95% CI, 0.24-0.53) dermatomes, and motor scores of the elbow flexors (C5) (OR, 0.74; 95% CI, 0.60-0.89) and wrist extensors (C6) (OR, 0.61; 95% CI, 0.49-0.75). A multivariable model including these variables had excellent discrimination in distinguishing dependent from independent patients in the temporal-validation cohort (C statistic, 0.90; 95% CI, 0.88-0.93). A clinical prediction score (range, 0 to 45 points) was developed based on these measures, with higher scores increasing the probability of dependency. The discrimination of the prediction score was significantly higher than from AIS grading (change in AUC, 0.14; 95% CI, 0.10-0.18; P < .001).

CONCLUSIONS AND RELEVANCE

The findings of this study suggest that this prediction rule may help prognosticate upper limb function following cervical SCI. This tool can be used to set patient expectations, rehabilitation goals, and aid decision-making regarding the appropriateness and timing for upper limb reconstructive surgeries.

Bladder Management With Chronic Indwelling Catheter is Associated with Elevated Mortality in Patients with Spinal Cord Injury

OBJECTIVE

To evaluate the impact of bladder management method, specifically chronic indwelling catheter (IndC), on survival in patients with spinal cord injury (SCI) in Spinal Cord Injury Model System database.

METHODS

Spinal Cord Injury Model System is a multicenter longitudinal database since 1970 with >40,000 patients with SCI. Adult patients (>18 at the time of injury) were screened. Patients who died within 1 year of injury and had 2 or more changes in method of bladder management, or reported normal volitional void were excluded. Outcome of interest was death from nonpulmonary, nonwound related sepsis (NPNWS). Left truncation cox regression method using age as the time-scale was used to calculate hazard ratios.

RESULTS

A total of 13,616 patients were included. Comparison was performed between "IndC" group (n = 4872; 36.1%) vs "Other" (n = 8744; 63.9%). After adjusting for age and change in bladder management method, "IndC" is associated with elevated NPNWS mortality (2.10; 95% confidence interval 1.72-2.56, P < .001). Multivariable analysis, adjusting for age at injury, gender, race, education, insurance status, etiology of SCI, injury level, neurologic impairment level, and change in bladder management method, showed IndC was associated with significantly higher risk of death from NPNWS compared to other methods of bladder management.

CONCLUSION

In a large cohort of SCI patients, bladder management with IndC is predictive of significantly propagated NPNWS related mortality compared to other methods of bladder management. While identifying IndC is an independent mortality risk factor, a better understanding of the underlying mechanisms could inform strategies to improve neurourological care and survival after SCI.

Demographic and Health Profiles of People Living With Traumatic Spinal Cord Injury in the United States During 2015-2019: Findings from the Spinal Cord Injury Model Systems Database

OBJECTIVE

To estimate the population profile of people living with traumatic spinal cord injury (TSCI) to help evaluate health care needs of this aging population.

DESIGN

Cross-sectional study.

SETTING

SCI Model Systems (SCIMS) centers in the United States.

PARTICIPANTS

Individuals (N=20,437) who: (1) incurred a TSCI between 1972 and 2019, (2) were initially treated at one of the SCIMS centers, and (3) were alive during the period from 2015 to 2019.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Demographics, injury characteristics, health conditions, and social participation, as compared with previous estimates in 2008 and general population statistics in 2017.

RESULTS

People living with TSCI during the period from 2015-2019 (mean years since injury, 18y; 79.4% male, and 62.5% White) were older (51.6 vs 45.0y) and had a higher percentage of C1-C4 (21.9% vs 17.0%) and American Spinal Injury Association Impairment Scale D injuries (31.5% vs 26.0%) compared with the 2008 TSCI population profile. Although the proportion of people with a bachelor's degree or higher was similar between the TSCI and general US populations (30.7% vs 32.0%), the employment rate was lower in the TSCI population (24.0% vs 59.5%). People are affected by various medical problems over time post TSCI. The prevalence of pain and urinary tract infection remained high over postinjury years, at 86.1% and 52.6%, respectively. Rehospitalization and depression were most common during the first year (34.9% and 22.3%, respectively), and pressure injury was more common among those 20 years or more postinjury (>30.0%). Health conditions declined with advanced age, including self-perceived health, diabetes, and institutional residence. People who survived TSCI for years, however, had relatively good degrees of independence and social participation.

CONCLUSION

Study findings highlight the need for greater involvement of primary care providers and geriatricians in the continuity of care for SCI to promote healthy aging. Improvement in employment should also be the target in promoting social participation and quality of life.

Changes in Internet Use Over Time Among Individuals with Traumatic Spinal Cord Injury

OBJECTIVE

To investigate the changes in total internet and mobile internet use over time and determine how demographic characteristics are related to changes in internet and mobile internet use among individuals with spinal cord injury (SCI).

DESIGN

Cross-sectional analysis of multicenter cohort study.

SETTING

National SCI Database.

PARTICIPANTS

Persons with traumatic SCI with follow-up data collected between 2012 and 2018 (n=13,622).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Proportion of sample reporting internet use at all or through a mobile device over time and specifically in 2018.

RESULTS

The proportion of internet users increased from 77.7% in 2012 to 88.1% in 2018. Older participants (p<0.001), those with lower annual income (p<0.001), less education (p<0.001), non-White race or Hispanic ethnicity (p<0.001), motor incomplete tetraplegia (p=0.004), or males (p=0.035) were less likely to use internet from 2012 to 2018. By 2018, there were no longer differences in internet use based upon race/ethnicity (p=0.290) or sex (p=0.066). Mobile internet use increased each year (52.4% to 87.7% of internet users from 2012 to 2018), with a participant being 13.7 times more likely to use mobile internet in 2018 than 2012. Older age (p<0.001), income less than $50,000 (p<0.001), high school diploma or less (p=0.011), or non-Hispanic White race/ethnicity (p=0.001) were associated with less mobile internet use over time. By 2018 there were no differences in mobile internet use by education (p=0.430) and only participants with incomes greater than $75,000/year had greater odds of mobile internet use (p=0.016).

CONCLUSIONS

Disparities associated with internet access are decreasing likely due to mobile device use. Increased internet access offers an important opportunity to provide educational and training materials to frequently overlooked groups of individuals with SCI.

Utilization of Complementary and Integrative Health Care by People With Spinal Cord Injury in the Spinal Cord Injury Model Systems: A Descriptive Study

OBJECTIVE

To characterize the use of complementary and integrative health care (CIH) by people with spinal cord injury.

DESIGN

Cross-sectional self-report study.

SETTING

Participants were recruited from 5 Spinal Cord Injury Model Systems (SCIMS) centers across the United States.

INTERVENTIONS

Not applicable.

PARTICIPANTS

A total of 411 persons enrolled in the SCIMS completing their SCIMS follow-up interview between January 2017 and July 2019 (N = 411).

MAIN OUTCOME MEASURES

Participants completed a survey developed for this study that included questions about types of CIH currently and previously used, reasons for current and previous use, reasons for discontinuing use of CIH, and reasons for never using CIH since injury.

RESULTS

Of the 411 respondents, 80.3% were current or previous users of CIH; 19.7% had not used CIH since injury. The most commonly used current types of CIH were multivitamins (40.0%) and massage (32.6%), whereas the most common previously used type of CIH was acupuncture (33.9%). General health and wellness (61.4%) and pain (31.2%) were the most common reasons for using CIH. The primary reason for discontinuing CIH was that it was not helpful (42.1%). The primary reason for not using CIH since injury was not knowing what options are available (40.7%).

CONCLUSIONS

These results point to the importance for rehabilitation clinicians to be aware that their patients may be using 1 or more CIH approaches. Providers should be open to starting a dialogue to ensure the health and safety of their patients because there is limited information on safety and efficacy of CIH approaches in this population. These results also set the stage for further analysis of this data set to increase our knowledge in this area.

Conductive chitosan/polyaniline hydrogel with cell-imprinted topography as a potential substrate for neural priming of adipose derived stem cells

Biophysical characteristics of engineered scaffolds such as topography and electroconductivity have shown potentially beneficial effects on stem cell morphology, proliferation, and differentiation toward neural cells. In this study, we fabricated a conductive hydrogel made from chitosan (CS) and polyaniline (PANI) with induced PC12 cell surface topography using a cell imprinting technique to provide both topographical properties and conductivity in a platform. The engineered hydrogel's potential for neural priming of rat adipose-derived stem cells (rADSCs) was determined in vitro. The biomechanical analysis revealed that the electrical conductivity, stiffness, and hydrophobicity of flat (F) and cell-imprinted (CI) substrates increased with increased PANI content in the CS/PANI scaffold. The conductive substrates exhibited a lower degradation rate compared to non-conductive substrates. According to data obtained from F-actin staining and AFM micrographs, both CI(CS) and CI(CS-PANI) substrates induced the morphology of rADSCs from their irregular shape (on flat substrates) into the elongated and bipolar shape of the neuronal-like PC12 cells. Immunostaining analysis revealed that both CI(CS) and CI (CS-PANI) significantly upregulated the expression of GFAP and MAP2, two neural precursor-specific genes, in rADSCs compared with flat substrates. Although the results reveal that both cell-imprinted topography and electrical conductivity affect the neural lineage differentiation, some data demonstrate that the topography effects of the cell-imprinted surface have a more critical role than electrical conductivity on neural priming of ADSCs. The current study provides new insight into the engineering of scaffolds for nerve tissue engineering.

A Qualitative Study of Caregiving for Adolescents and Young Adults With Spinal Cord Injuries: Lessons From Lived Experiences

Objective: To examine characteristics of caregiving from the perspectives of adolescents and young adults (AYAs) with spinal cord injuries (SCIs) and their informal caregivers to address outstanding gaps in knowledge relating to definitions of caregiving and its associated practices for this population. Methods: A multiphase qualitative design was applied, using phenomenological and narrative methods to capture data in participants' homes and communities. Participants were recruited from rehabilitation hospitals and community organizations throughout Los Angeles County, California. Inclusion criteria for AYAs included being 15-22 years old, having acquired an SCI within the previous 5 years, and using a wheelchair for mobility. The AYAs nominated persons they identified as primary caregivers to also participate. Data were collected through individual and group interviews as well as activity observations. Results: Data from the 17 participants (9 AYAs and 8 informal, primary caregivers) revealed ways in which the meaning of caregiving varied among dyads. Caregiving practices extended beyond physical assistance to include support for a range of day-to-day activities spanning from practical needs to facilitating developmental trajectories. Although AYAs expressed ideas about preferred caregiver characteristics, care partnerships appeared to be guided more by availability than preference. Conclusion: Phenomenological analysis revealed that the meaning of "caregiving" and its associated practices are highly individualized for AYAs with SCIs. Caregiving is rooted in personal needs related to effects of SCI and developmental goals. Everyday practices are shaped by individual relationships and the beliefs of AYAs and their caregivers. Addressing influences of caregiving on long-term health and function may require attention to developmental processes, caregiver "fit," and ways care is, or can be, distributed throughout broader networks according to personal needs and preferences.
