Ageing with spinal cord injury: cross-sectional and longitudinal effects

Body size interacts with the structure of the central nervous system: A multi-center in vivo neuroimaging study

Clinical research emphasizes the implementation of rigorous and reproducible study designs that rely on between-group matching or controlling for sources of biological variation such as subject's sex and age. However, corrections for body size (i.e. height and weight) are mostly lacking in clinical neuroimaging designs. This study investigates the importance of body size parameters in their relationship with spinal cord (SC) and brain magnetic resonance imaging (MRI) metrics. Data were derived from a cosmopolitan population of 267 healthy human adults (age 30.1±6.6 years old, 125 females). We show that body height correlated strongly or moderately with brain gray matter (GM) volume, cortical GM volume, total cerebellar volume, brainstem volume, and cross-sectional area (CSA) of cervical SC white matter (CSA-WM; 0.44≤r≤0.62). In comparison, age correlated weakly with cortical GM volume, precentral GM volume, and cortical thickness (-0.21≥r≥-0.27). Body weight correlated weakly with magnetization transfer ratio in the SC WM, dorsal columns, and lateral corticospinal tracts (-0.20≥r≥-0.23). Body weight further correlated weakly with the mean diffusivity derived from diffusion tensor imaging (DTI) in SC WM (r=-0.20) and dorsal columns (-0.21), but only in males. CSA-WM correlated strongly or moderately with brain volumes (0.39≤r≤0.64), and weakly with precentral gyrus thickness and DTI-based fractional anisotropy in SC dorsal columns and SC lateral corticospinal tracts (-0.22≥r≥-0.25). Linear mixture of sex and age explained 26±10% of data variance in brain volumetry and SC CSA. The amount of explained variance increased at 33±11% when body height was added into the mixture model. Age itself explained only 2±2% of such variance. In conclusion, body size is a significant biological variable. Along with sex and age, body size should therefore be included as a mandatory variable in the design of clinical neuroimaging studies examining SC and brain structure.

Pain interference and depressive symptom severity across 10 years in individuals with long-term spinal cord injury

OBJECTIVE

To examine change in pain interference and depression over a 10-year time period in individuals with long-term traumatic spinal cord injury (SCI) and to identify the extent to which changes in pain interference over time predicts change in depressive symptoms.

DESIGN

Longitudinal analyses of self-report assessment data.

SETTING

Specialty and university hospitals in the Southeastern and Midwestern United States.

PARTICIPANTS

Adults with a history of traumatic SCI (n = 504) who responded to the three most recent data collection periods of the SCI Longitudinal Aging Study (2008 [Time 1], 2013 [Time 2], and 2018 [Time 3]). The participants averaged 59 years of age and 32 years since injury onset at Time 3.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Patient Health Questionnaire (PHQ-9) assessed depressive symptom severity. The 7-item Pain Interference scale from the Brief Pain Inventory assessed pain interference.

RESULTS

Over the three study timepoints, the sample averaged moderate levels of pain interference and mild depressive symptom severity. Unconditional linear growth models, reflecting changes in central tendency, indicated that pain interference significantly decreased and depressive symptom severity significantly increased over time. Multiple independent variables random coefficient modeling based on correlations suggested that change in pain interference was positively associated with change in depressive symptom severity over the 10-year study follow-up.

CONCLUSION

Average depressive symptom severity worsened over time. Change in pain interference was positively associated with change in depressive symptom severity. These results point to the complexity of aging related changes in depressive symptoms and pain interference. They further support the need for continued assessment of mood and pain experiences, particularly among individuals reaching aging milestones with SCI.

Long-term prediction of functional independence using adjusted and unadjusted single items of the functional independence measure (FIM) at discharge from rehabilitation

CONTEXT

Being able to survive in the long-term independently is of concern to patients with spinal cord injury (SCI), their relatives, and to those providing or planning health care, especially at rehabilitation discharge. Most previous studies have attempted to predict functional dependency in activities of daily living within one year after injury.

OBJECTIVES

(1) build 18 different predictive models, each model using one FIM (Functional Independence Measure) item, assessed at discharge, as independent predictor of total FIM score at chronic phase (3-6 years post-injury) (2) build three different predictive models, using in each model an item from a different FIM domain with the highest predictive power obtained in objective (1) to predict "good" functional independence at chronic phase and (3) adjust the 3 models from objective (2) with known confounding factors.

METHODS

This observational study included 461 patients admitted to rehabilitation between 2009 and 2019. We applied regression models to predict total FIM score and "good" functional independence (FIM motor score ≥ 65) reporting adjusted R², odds ratios, ROC-AUC (95% CI) tested using 10-fold cross-validation.

RESULTS

The top three predictors, each from a different FIM domain, were Toilet (adjusted R² = 0.53, Transfers domain), Toileting (adjusted R² = 0.46, Self-care domain), and Bowel (adjusted R² = 0.35, Sphincter control domain). These three items were also predictors of "good" functional independence (AUC: 0.84-0.87) and their predictive power increased (AUC: 0.88-0.93) when adjusted by age, paraplegia, time since injury, and length of stay.

CONCLUSIONS

Discharge FIM items accurately predict long-term functional independence.

Detecting subgroups in social participation among individuals living with spinal cord injury: a longitudinal analysis of community survey data

STUDY DESIGN

Longitudinal community survey.

OBJECTIVES

To determine subgroups in social participation of individuals living with spinal cord injury (SCI).

SETTING

Community.

METHODS

Data were collected in 2012 and 2017 as part of the community survey of the Swiss Spinal Cord Injury cohort. Participation was assessed using the 33-item Utrecht Scale of Evaluation of Rehabilitation-Participation evaluating frequency of, restrictions in and satisfaction with productive, leisure, and social activities. Linear mixed-effects model trees were used to distinguish subgroups in participation associated with sociodemographic and lesion characteristics.

RESULTS

In all, 3079 observations were used for the analysis, of which 1549 originated from Survey 2012, 1530 from Survey 2017, and 761 from both surveys. Participants were mostly male (2012: 71.5%; 2017: 71.2%), aged on average 50 years (2012: 52.3; 2017: 56.5), with an incomplete paraplegia (2012: 37.5%; 2017: 41.8%) of traumatic origin (2012: 84.7%; 2017: 79.3%). There was limited within-person variation in participation over the 5-year period. Participation varied with age, SCI severity, education, financial strain, number of self-reported health conditions (SHCs), and disability pension level. Among modifiable parameters, the number of SHCs and disability pension level emerged as the most frequent partitioning variables, while education was most informative for participation in productive, leisure, and social activities.

CONCLUSIONS

Long-term rehabilitation management and clinical practice should target people most prone to decreased participation in major life domains. Our study indicates that the alleviation of SHCs, engagement in further education, or adjusting disability pension level are promising areas to improve participation of persons living with SCI.

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.

Functional independence of persons with long-standing motor complete spinal cord injury in the Netherlands

Context/Objective: Since life expectancy of persons with spinal cord injury (SCI) has improved, it is relevant to know whether this group is able to maintain functional abilities many years after onset of SCI. Objectives of this study were (1) to examine associations between time since injury (TSI) and functional independence in persons with long-standing SCI and (2) to explore associations between functional independence and level of injury, comorbidities, mental health, waist circumference and secondary health conditions (SHCs).Design: TSI-stratified cross-sectional study. Strata were 10-19, 20-29 and 30+ years.Setting: Community.Participants: 226 persons with long-standing SCI. Inclusion criteria: motor complete SCI; age at injury 18-35 years; TSI ≥ 10 years; current age 28-65 years; wheelchair dependency.Interventions: Not applicable.Outcome measures: The Spinal Cord Independence Measure III (SCIM) was administered by a trained research assistant. Level of injury, comorbidities, mental health, waist circumference and SHCs were assessed by a rehabilitation physician.Results: Mean TSI was 23.6 (SD 9.1) years. No significant differences in SCIM scores were found between TSI strata. SCIM scores were lower for persons with tetraplegia, autonomic dysreflexia, hypotension, more than four SHCs and a high waist circumference. In linear regression analyses, TSI nor age was associated with the SCIM total score. Only level of injury (β = -0.7; P < .001) and waist circumference (β = -0.1; P = .042) were independent determinants (explained variance 55%).Conclusion: We found no association between TSI and functional independence in persons with long-standing motor complete SCI. This study confirms the possible effect of overweight on functional independence.

Perceived social support as a moderator between perceived discrimination and subjective well-being among people with physical disabilities in Israel

PURPOSE

Perceived social support has gained importance as a significant preventive factor of depressive symptoms and as helpful for rebuilding feelings of self-worth and subjective well-being among people with physical disabilities. The current study examined whether perceived social support moderates the association between perceived discrimination and subjective well-being among people with physical disabilities in Israel.

MATERIALS AND METHODS

Data were collected by means of structured questionnaires among a convenience sample of 433 people with physical disabilities in Israel and hierarchical multiple regression was performed.

RESULTS AND CONCLUSIONS

The findings reveal that perceived social support has a moderating role in the association between perceived discrimination and subjective well-being among people with physical disabilities, such that those with low and moderate levels of perceived social support showed a negative association between perceived discrimination and subjective well-being, while those with high levels of perceived social support showed no association between perceived discrimination and subjective well-being. Findings are discussed in light of the social model of disability, and practical implications are suggested. Implications for Rehabilitation A negative association was found between perceived discrimination and subjective well-being among people with physical disabilities with low and moderate levels of perceived social support. Professionals working with people with physical disabilities must acknowledge the importance of social support for people with physical disabilities and for their families. Professionals working with people with physical disabilities should take a proactive approach to locating disabled people who do not receive or do not have adequate social support and offer them assistance. Professionals working with people with physical disabilities should engage in wide social activities aimed at providing resources and opportunities to service beneficiaries. Society bears the collective responsibility to act in order to reduce the social problem of discrimination against people with disabilities, as well as to raise public awareness of this issue.

The natural course of spinal cord injury: changes over 40 years among those with exceptional survival

OBJECTIVES

To identify 40-year longitudinal changes in health, activity, employment, life satisfaction and self-rated adjustment after spinal cord injury.

STUDY DESIGN

Longitudinal, mailed self-report.

METHODS

Participants were identified from outpatient records of a Midwestern USA university hospital in 1973. Follow-ups were conducted in 1984 and approximate 10-year intervals thereafter. A total of 49 participants completed each of the five assessments. Data were reviewed and analyzed by research team members and a research associate with experience in biostatistics at a medical university in Southeastern USA. Life Situation Questionnaire included the following: (1) demographic and injury characteristics, (2) educational status and employment, (3) community participation, (4) life satisfaction, (5) adjustment, and (6) recent medical history.

RESULTS

Proportion of individuals with 10+ non-routine physician visits increased from consistently <10% to >40% during the 40 years. Proportion who spent a week or more in hospital increased from a low of 10% at 20-year follow-up to 43% at 40-year follow-up. Percentage employed and average hours employed initially improved over time but decreased substantially during the last two times of measurement. Satisfaction with health, sex life and social life declined over time, whereas satisfaction with employment improved initially and was maintained over time. Self-rated current adjustment remained stable, whereas predicted future adjustment declined steadily over 40 years.

CONCLUSIONS

Age-related declines were apparent for need of physician visits and hospitalizations, with notable declines in satisfaction with sex life, social life and health. However, not all indices declined over time. Participants appeared to maintain stability when rating their own adjustment.

Community participation for individuals with spinal cord injury living in Queensland, Australia

STUDY DESIGN

Sequential mixed method design.

OBJECTIVES

Determine factors associated with community participation for individuals with spinal cord injury (SCI).

SETTING

Queensland, Australia.

METHODS

Phase I consisted of a quantitative telephone survey of 270 people who had sustained a SCI within the past 50 years. To verify and interpret survey findings, Phase II involved a qualitative investigation. One focus group, one dyadic and one in-depth interview were conducted with a separate sample of eight people who had sustained a SCI within the past 50 years.

RESULTS

In Phase I, employment, paid or unpaid, was the strongest independent factor associated with community participation, whereas time since injury, completeness of injury, secondary conditions and functional independence were also independently associated. In Phase II, participants expressed that survey findings were consistent with their lived experiences. They explained that overall, they needed a strong reason to participate so that benefits outweigh the effort required to participate. Once out in the community, they recognised that other opportunities for participation arise.

CONCLUSION

Rehabilitation services need to support individuals with SCI to find meaningful employment and to engage in activities that provide them with a strong reason to participate.

Age-related variation in mobility independence among wheelchair users with spinal cord injury: A cross-sectional study

OBJECTIVE

To evaluate age-related variation in mobility independence among community-living wheelchair users with spinal cord injury (SCI).

DESIGN

Community Survey (2011-2013) as part of the Swiss Spinal Cord Injury Cohort Study.

SETTING

Community.

PARTICIPANTS

Individuals aged 16 years or older with traumatic or non-traumatic SCI permanently residing in Switzerland and using a wheelchair for moving around moderate distances (10-100 m).

INTERVENTIONS

Not applicable.

OUTCOME MEASURES

Mobility-related items of the Spinal Cord Independence Measure-Self Report were matched to the three principal domains "changing basic body position," "transferring oneself" and "moving around." Binary outcomes ("independence" vs. "no independence") were created for every domain and analyzed using multivariable logistic regression (adjusted for sex, socioeconomic factors, SCI characteristics, and health conditions).

RESULTS

Regression analyses (N = 949; 27% women; median age 51, interquartile range 41-61) showed a decline in the odds of independence (odds ratio; 95% confidence interval) with increasing age for "changing basic body position" (age 16-30 (reference), 31-45 (0.99; 0.53-1.83), 46-60 (0.64; 0.33-1.21), 61-75 (0.45; 0.22-0.92), 76+ (0.18; 0.07-0.44); P < 0.001), "transferring oneself" (age 16-30 (reference), 31-45 (0.77; 0.37-1.61), 46-60 (0.39; 0.18-0.84), 61+ (0.05; 0.02-0.14); P < 0.001), and "moving around" (age 16-30 (reference), 31-45 (0.79; 0.42-1.48), 46-60 (0.49; 0.26-0.94), 61-75 (0.49; 0.24-1.01), 75+ (0.11; 0.04-0.30); P < 0.001).

CONCLUSIONS

Mobility independence was negatively associated with age in wheelchair users with SCI. Future longitudinal analyses are required to gain further insights into the causal factors for the age-related decline.

Long-term change in respiratory function following spinal cord injury

STUDY DESIGN

Retrospective study.

OBJECTIVES

To model the effect of time since injury on longitudinal respiratory function measures in spinal cord injured-individuals and to investigate the effect of patient characteristics.

SETTING

A total of 173 people who sustained a spinal cord injury between 1966 and April 2013 and who had previously participated in research or who underwent clinically indicated outpatient respiratory function tests at the Austin Hospital in Melbourne, Australia, were included in the study. At least two measurements over time were available for analysis in 59 patients.

METHODS

Longitudinal data analysis was performed using generalised linear regression models to determine changes in respiratory function following spinal cord injury from immediately post injury to many years later. Secondly, we explored whether injury severity, age, gender and body mass index (BMI) at injury altered the time-dependent change in respiratory function.

RESULTS

The generalised linear regression model showed no significant change (P=0.276) in respiratory function measured in (forced) vital capacity ((F)VC) after the spinal cord injury. However, significant (P<0.05) differences in respiratory function over time were found when categorising age and BMI.

CONCLUSION

This clinical cohort with long-term, repeated measurements of respiratory function showed no significant overall change in respiratory function over 23 years. However, a decline in respiratory function over time was observed in subgroups of individuals older than 30 years at the onset of injury and in those with a BMI>30 kg m(-2).

Longitudinal changes in medical complications in adults with pediatric-onset spinal cord injury

OBJECTIVES

To determine longitudinal changes in the occurrence of medical complications in adults with pediatric-onset spinal cord injury (SCI).

DESIGN

Longitudinal study of long-term outcomes.

SETTING

Community.

PARTICIPANTS

Individuals who had sustained an SCI before age 19, were 23 years of age or older at initial interview, and followed annually between 1996 and 2011. They were classified into four American Spinal Injury Association (ASIA) Impairment Scale (AIS) severity groups: C1-4 AIS ABC, C5-8 AIS ABC, T1-S5 AIS ABC, AIS D.

OUTCOME MEASURES

Generalized estimating equation (GEE) models were formulated to obtain the odds ratio (OR) of having a medical complication over time.

RESULTS

A total of 1793 interviews were conducted among 226 men and 125 women (86% Caucasian; age at baseline, 26.7 ± 3.6 years; time since injury at baseline, 12.9 ± 5.2 years). Odds of complication occurrence over time varied among severity groups, with increased ORs of severe urinary tract infection (1.05, confidence interval (CI) 1.02-1.09), autonomic dysreflexia (AD) (1.09, CI 1.05-1.14), spasticity (1.06, CI 1.01-1.11), pneumonia/respiratory failure (1.09, CI 1.03-1.16), and hypertension/cardiac disease (1.07, CI 1.01-1.15) in the C1-4 ABC group; AD (1.08, CI 1.04-1.13) and pneumonia/respiratory failure (1.09, CI 1.02-1.16) in the C5-8 ABC group; and hypertension/cardiac disease (1.08, CI 1.02-1.14) in the T1-S5 ABC group. Upper extremity joint pain had increased odds of occurrence in all injury severity groups.

CONCLUSION

The significantly increased odds of having medical complications over time warrants awareness of risk factors and implementation of preventive measures to avoid adverse consequences of complications and to maintain independence in individuals with pediatric-onset SCI.

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

STUDY DESIGN

Scoping review.

OBJECTIVES

To gain a better understanding of the prevalence, course and association with age of secondary health conditions in individuals with spinal cord injury (SCI).

SETTING

Seattle, Washington, USA.

METHODS

We performed searches of electronic databases for studies published from 1986-2011 that provided information regarding the prevalence, course or associations with age and duration of secondary health conditions in individuals with SCI.

RESULTS

Ninety-two studies were included. The findings indicate that: (1) individuals with SCI experience a number of secondary health conditions, many of which occur at a higher rate in those with SCI than the normative population; (2) the most common conditions or symptoms are pain, bowel and bladder regulation problems, muscle spasms, fatigue, esophageal symptom and osteoporosis; (3) a number of conditions, including cardiovascular disease, diabetes, bone mineral density loss, fatigue and respiratory complications or infections, occur with higher frequency in older individuals or those with longer SCI duration, relative to younger individuals or those with shorter SCI duration; and (4) there is a marked lack of longitudinal research examining the natural course of health conditions in individuals aging with SCI.

CONCLUSIONS

The findings support the conclusion that individuals with SCI show signs of 'premature aging' in different organ systems. Longitudinal research is needed to understand when problems are most likely to emerge, and to develop and test the efficacy of interventions to prevent these health conditions and their negative impact.

The association of age, pain, and fatigue with physical functioning and depressive symptoms in persons with spinal cord injury

CONTEXT/OBJECTIVE

To describe the relationship of pain and fatigue with physical and psychological functioning in adults with spinal cord injury (SCI).

DESIGN

Cross-sectional survey.

SETTING

Community-based survey.

PARTICIPANTS

Convenience sample of individuals with SCI.

INTERVENTION

Not applicable.

OUTCOME MEASURES

Physical functioning (Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Functioning item bank items), depression (Patient Health Questionnaire-9 (PHQ-9)), pain severity (0-10 Numerical Rating Scale (NRS)), and fatigue (0-10 NRS).

RESULTS

Pain and fatigue were independently associated with depression, but only pain was associated with physical functioning. Additionally, depression was more severe among middle-aged participants relative to younger or older participants. Physical functioning declined with increasing age, as well as with higher level of injury.

CONCLUSIONS

The findings support the need for continued development of effective treatments for both pain and fatigue in order to prevent and mitigate the negative effects these symptoms can have on functioning.

International spinal cord injury musculoskeletal basic data set

OBJECTIVES

To develop an International Spinal Cord Injury (SCI) Musculoskeletal Basic Data Set as part of the International SCI Data Sets to facilitate consistent collection and reporting of basic musculoskeletal findings in the SCI population.

SETTING

International.

METHODS

A first draft of an SCI Musculoskeletal Basic Data Set was developed by an international working group. This was reviewed by many different organizations, societies and individuals over 9 months. Revised versions were created successively.

RESULTS

The final version of the International SCI Musculoskeletal Basic Data Set contains questions on neuro-musculoskeletal history before spinal cord lesion; presence of spasticity/spasms; treatment for spasticity within the last 4 weeks; fracture(s) since the spinal cord lesion; heterotopic ossification; contracture; the location of degenerative neuromuscular and skeletal changes due to overuse after SCI; SCI-related neuromuscular scoliosis; the method(s) used to determine the presence of neuromuscular scoliosis; surgical treatment of the scoliosis; other musculoskeletal problems; if any of the musculoskeletal challenges above interfere with activities of daily living. Instructions for data collection and the data collection form are freely available on the International Spinal Cord Society (ISCoS) website (www.iscos.org.uk).

CONCLUSION

The International SCI Musculoskeletal Basic Data Set will facilitate consistent collection and reporting of basic musculoskeletal findings in the SCI population.

Lessons for spinal cord injury rehabilitation taken from adult developmental psychology: 2011 Essie Morgan Lecture

BACKGROUND/OBJECTIVE

Developmental phases affect how individuals cope with and challenge threats to self-concept, health and functioning. Understanding prominent models of adult psychological development can help spinal cord injury/disease (SCI/D) rehabilitation professionals facilitate positive change and growth.

DESIGN

Author's theoretical model informed by literature review and personal experience.

SETTING

Veterans administration (VA) medical center interdisciplinary outpatient clinic providing primary and specialty care to veterans with spinal cord injuries and disorders.

CONCLUSION

Threats to life expectations, health, well-being, identity, and other aspects of self create crises that can result in psychopathology or psychological growth. SCI/D can present multiple threats across the lifespan. For example, self-image, ability to perform various activities, ability to feel attractive, and even life itself may be challenged by SCI/D or its complications. Threats may be perceived at the time of injury or onset of symptoms. Also, as the injured body declines further over time, complications can cause significant temporary or permanent functional decline. Individuals interpret each of these threats in the context of current developmental needs. How people cope is influenced by developmental factors and personality traits. An integrated model of adult psychological development based on the works of Erikson, Gutmann, and Baltes is related to the literature on coping with SCI/D. This model provides insights that interdisciplinary rehabilitation teams may use to facilitate personal growth, optimal functioning, and physical health as adults with SCI negotiate normal developmental challenges throughout their lifetimes.

Pathways of change experienced by people aging with disability: a focus group study

PURPOSE

To examine the issues related to aging with disability from the perspective of the person with the disabilities.

METHOD

Twelve community-dwelling adults with spinal cord injury (SCI), post-polio syndrome (PPS) or multiple sclerosis (MS) participated in focus groups where they were asked open-ended questions about changes related to aging with disability, accommodations made and perspectives on the future.

RESULTS

Results of qualitative analysis suggested five major themes related to aging with a disability: (1) Participant identity, including comments about how participants described themselves and their lives with a long-standing disability; (2) Physical pathways including comments about the progression of physical symptoms; (3) Psychosocial pathways, including descriptions of adaptations to disability, the development of emotional well-being and strategies to deal with disability; (4) Changing health care, reflecting improvement noted over time in health care services; and (5) Concerns about the future, including comments reflecting participant uncertainty about the potential course of disability.

CONCLUSIONS

The process of aging with disability was characterised by multiple pathways. Some, including positive psychosocial adjustment and medical advancements, were favourable, while others, including physical decline, were not. The co-existence of high quality of life in the presence of physical decline is consistent with a larger literature in older adults, and future research should focus on identifying aging factors that may contribute to the buffering the psychological impact of physical decline.

An evidence-based review of aging of the body systems following spinal cord injury

STUDY DESIGN

Systematic review.

OBJECTIVE

To systematically review evidence on aging of the body systems after spinal cord injury (SCI).

SETTING

Toronto, Ontario and Vancouver, British Columbia, Canada.

METHODS

Electronic databases (MEDLINE/PubMed, CINAHL, EMBASE and PsycINFO), were searched for studies published between 1980 and 2009. The search was augmented by reviewing the reference lists of relevant papers. Non-intervention studies that were longitudinal or cross-sectional with able-bodied controls that were at minimum matched on chronological age were included for review. Levels of evidence were assigned to the study design using a modified Sackett scale.

RESULTS

Of the 74 studies selected for inclusion, 16 were longitudinal in design. The hypothesis that SCI represents a model for premature aging is supported by a large proportion of level 5 evidence for the cardiovascular and endocrine systems, level 2, 4 and 5 evidence for the musculoskeletal system, and limited level 5 evidence for the immune system. Only a few level 4 and 5 studies for the respiratory system were found. The evidence on the genitourinary system, gastrointestinal system, and for skin and subcutaneous tissues provide level 4 and 5 evidence that premature aging may not be occurring. The evidence on the nervous system does not provide evidence of premature aging as a result of SCI.

CONCLUSIONS

Premature aging appears to occur in some systems after SCI. Additional longitudinal studies are required to confirm these findings.

Goal striving and maladaptive coping in adults living with spinal cord injury: associations with affective well-being

OBJECTIVE

The current study examined how goal engagement and two coping strategies (self-blame and denial) hypothesized to prevent successful disengagement relate to affective well-being among adults with a functional disability.

METHOD

Ninety-nine community-dwelling adults (23 to 76 years old, 66 men) with spinal cord injury participated in structured interviews assessing affective well-being using the Positive and Negative Affect Scale (Watson, Clark, & Tellegen, 1988); goal engagement using a modified version of the Optimization, Primary, and Secondary Control Scale (Heckhausen, Schulz, & Wrosch, 1998); and self-blame and denial using items from Carver's (1997) Brief COPE Inventory.

RESULTS

Greater goal engagement was significantly associated with positive but not negative affect. Greater use of self-blame and denial coping was associated with lower positive affect for older adults and higher negative affect across the age range.

IMPLICATIONS

Pain after paraplegia: a survey in India

STUDY DESIGN

A postal survey.

OBJECTIVE

To ascertain the incidence of pain in individuals with paraplegia in India and to associate it with demographic characteristics.

SETTING

India.

METHOD

The study was done by means of a questionnaire. This questionnaire was mailed to the identified individuals (n=600) on the addresses obtained from the medical records section of hospitals and from various organizations. Data analysis was done by using non-parametric tests of association.

RESULTS

The return rate was 46% (276/600). Fifty-seven percent of individuals complained of pain. Of this, pain in the back and chest ranked the highest (30.1%), followed by pain below the level of lesion (6.9%), pain in the shoulder and upper limb (4.7%) and neck (0.4%). Fifteen percent of individuals complained of pain at multiple sites. We found a significant association of pain with age, duration since injury and ambulation.

CONCLUSION

More than half of the subjects complained of pain in the study. Pain was found to be associated with age, duration since injury and ambulation. As pain has a dramatic effect on a subjects' quality of life, there is a need to evaluate it in detail and treat accordingly with preventive, rehabilitative or surgical procedures.

'Reserve is no place for a wheelchair': challenges to consider during wheelchair provision intended for use in First Nations community

PURPOSE

The purpose of this study was to gain an understanding of the post-rehabilitation experiences of First Nations persons with spinal cord injury who returned to live on reserve using a wheelchair.

METHOD

A phenomenological approach with purposive sampling was employed to recruit participants with spinal cord injuries who used a wheelchair and lived in a First Nations community. Data were collected using a short demographic questionnaire and a semi-structured interview.

RESULTS

Most participants returned to live on reserve in homes that were not wheelchair accessible and only two had home assessments completed. Nearly all either moved to modified homes or had homes purpose built for them after waiting considerable periods of time to relocate. However, only one of these homes was considered completely accessible. Participants identified other challenges they coped with including the effects of other medical conditions, negotiating reserve terrain and accessing cultural activities.

CONCLUSIONS

The findings show that policy changes are required regarding the allocation of funding to ensure accessible on reserve housing for First Nations persons with a SCI. Further recommendations were made regarding the cultural content of health professional curricula as well as the need for health professionals to liaison more closely with Aboriginal health care workers.

What are the risk factors of occurence and chronicity of neuropathic pain in spinal cord injury patients?

OBJECTIVE

Analyze the epidemiological data on neuropathic pain in spinal cord injury patients and determine the risk factors for its occurrence and chronicity.

METHOD

Review and analysis of the literature.

RESULTS

Epidemiological data report that 40% of spinal cord injury (SCI) patients suffer from neuropathic pain and 40% of these patients report an intense neuropathic pain. Some factors do not seem to be predictive for the onset of neuropathic pain: the level of injury, complete or incomplete injury, the existence of an initial surgery, sex. However, old age at the time of injury, bullet injury as the cause of trauma, early onset of pain in the weeks following the injury, their initial nature, intensity and continuous pain, as well as associated symptoms all appear to be negative prognostic factors.

CONCLUSION

Neuropathic pain in SCI patients is a major issue, its determining factors still need to be evaluated properly by refining the epidemiological data.

Changes and determinants of life satisfaction after spinal cord injury: a cohort study in the Netherlands

OBJECTIVE

To determine the impact of spinal cord injury (SCI) on life satisfaction of persons with SCI 1 year after discharge of inpatient rehabilitation.

DESIGN

A cohort study. Life satisfaction before SCI was retrospectively measured at the start of active rehabilitation. One year after discharge from inpatient rehabilitation, current life satisfaction was measured.

SETTING

Eight rehabilitation centers in The Netherlands.

PARTICIPANTS

Persons (N=147) aged 18 to 65 and wheelchair-dependent at least for long distances.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

The Life Satisfaction Questionnaire.

RESULTS

Mean satisfaction with life +/- SD as a whole was 5.3+/-0 before SCI and 4.3+/-1.3 one year after inpatient rehabilitation. Sexual life, self-care, and vocational situation showed the largest impact of SCI (P<.05), whereas the social relationships domains appeared to be the least affected. Decrease of life satisfaction after SCI was larger when using the retrospective ratings than when using general population scores. Significant determinants of life satisfaction after SCI were high lesion level (beta=.31, P<.05), pain (beta=.19, P<.05), and secondary impairments (beta=.22, P<.05).

CONCLUSIONS

Life satisfaction decreased in persons with SCI. Level of lesion and suffering secondary impairments or pain were associated with low life satisfaction 1 year after discharge from inpatient rehabilitation.

The relationship between quality of life and disability across the lifespan for people with spinal cord injury

STUDY DESIGN

Prospective cross-sectional survey.

OBJECTIVES

To compare quality of life (QOL) for people with spinal cord injury (SCI) and their able-bodied peers and to investigate the relationship between QOL and disability (impairments, activity limitations and participation restrictions) across the lifespan, for people with SCI.

SETTING

A community outreach service for people with SCI in Queensland, Australia.

METHODS

A random sample of 270 individuals who sustained SCI during the past 60 years was surveyed using a guided telephone interview format. The sample was drawn from the archival records of a statewide rehabilitation service. QOL was measured using the World Health Organization Quality of Life Assessment Instrument-Bref, impairment was measured according to the American Spinal Injury Association classification and the Secondary Condition Surveillance Instrument, activity limitations using the motor subscale of the Functional Independence Measure and participation restrictions using the Community Integration Measure. Lifespan was considered in terms of age and time since injury. Correlation and regression analyses were employed to determine the relationship between QOL and components of disability across the lifespan.

RESULTS

QOL was significantly poorer for people with SCI compared to the Australian norm. It was found to be associated with secondary impairments, activity limitations and participation restrictions but not with neurological level, age or time since injury. The single most important predictor of QOL was secondary impairments whereas the second most important predictor was participation.

CONCLUSION

To optimize QOL across the lifespan, rehabilitation services must maintain their focus on functional attainment and minimizing secondary conditions, although at the same time enabling participation.

A guideline-driven assessment of need for cardiovascular disease risk intervention in persons with chronic paraplegia

OBJECTIVE

To examine percentages of persons with chronic paraplegia who qualify for lipid-lowering therapeutic lifestyle intervention (TLI) as assessed by authoritative guidelines.

DESIGN

Cross-sectional.

SETTING

Academic medical center.

PARTICIPANTS

Forty-one subjects (mean age +/- standard deviation, 34+/-11 y) with motor-complete paraplegia (American Spinal Injury Association grade A or B) at T6-L1 levels for greater than 2 years.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Percentages of subjects qualifying for TLI were independently assessed and then compared using National Cholesterol Education Project Adult Treatment Panel (ATP) II (1994) and ATP III (2002) Guidelines.

RESULTS

A total of 34.1% of subjects qualified for intervention based on the ATP II Guidelines and 63.4% based on ATP III (chi1(2) test=4.53; 2-tailed, P=.003). Seventy-six percent (31/41) of study participants had high-density lipoprotein cholesterol levels below the high-risk criterion of 40 mg/dL established by ATP III. Almost one third of subjects had hypertension, and 34.1% satisfied criteria for diagnosis of the metabolic syndrome.

CONCLUSIONS

A high percentage of young, apparently healthy people with chronic paraplegia are at risk for cardiovascular disease and qualify for lipid-lowering TLI. Updated guidelines of the ATP III have increased the urgency for early risk assessment and intervention.

Factors associated with health-related quality of life in chronic spinal cord injury

OBJECTIVE

An important goal of rehabilitation and treatment after spinal cord injury (SCI) is to improve function and enhance health-related quality of life (HRQoL). However, previous assessments are limited by use of HRQoL instruments not specific to SCI. Although respiratory dysfunction is common in SCI, it has not been possible to assess the association of comorbid medical conditions, including respiratory symptoms and pulmonary function, to HRQoL. Therefore, we assessed whether these factors were associated with HRQoL in SCI using an SCI-specific HRQoL questionnaire.

DESIGN

In our cross-sectional study, 356 participants >or=1 yr post-SCI completed a 23-item SCI-specific HRQoL questionnaire and a detailed health questionnaire, and underwent pulmonary function testing and a neurological exam at VA Boston between 1998 and June 2003.

RESULTS

In a multivariate regression model, age, employment status, motor level and completeness of injury, and ambulatory mode (use of hand-propelled or motorized wheelchair, use of crutches or canes, or walking independently) were independently associated with HRQoL. After adjusting for these factors, chronic cough, chronic phlegm, persistent wheeze, dyspnea with activities of daily living, and lower forced expiratory volume in 1 sec and forced vital capacity were each associated with a lower HRQoL.

CONCLUSIONS

These results provide evidence for the clinical validity of our SCI-specific HRQoL instrument. We also identify potentially modifiable factors that, if addressed, may lead to HRQoL improvement in SCI.

Paraplegia: a postal survey of morbidity trends in India

STUDY DESIGN

Postal survey from August 2004 to May 2006.

OBJECTIVE

To ascertain the morbidity trends in individuals with paraplegia in India and to find its association with demographic characteristics.

SETTINGS

India.

METHODS

The questionnaire was mailed to the identified individuals (n=600) whose addresses were obtained from the medical records section of our hospital and by contacting non-government organizations (NGOs), working for individuals with paraplegia in various cities. The causes of morbidities surveyed were respiratory complications, use of catheter, pressure sores, spasticity, postural hypotension, pain and fractures. Data were analysed using nonparametric test of association (Goodman Kruskal Tau).

RESULTS

A total of 276 (46%) individuals responded. Of all the morbidities studied, pain was the leading cause (57.2%) followed by spasticity (39.1%), pressure sore (28.3%), postural hypotension (10.1%), respiratory complications, and fractures (5.8%). We found significant associations between various morbidities and demographics and between morbidities themselves.

CONCLUSION

The most common cause for morbidity was pain. Ambulation reduced the incidence of secondary complications.

Prediction of long-term occupational performance outcomes for adults after moderate to severe traumatic brain injury

PURPOSE

To examine predictors of long-term occupational performance outcomes for adults after moderate to severe traumatic brain injury (TBI).

METHOD

This study involved analysis of data from a retrospective cohort of adults (N = 306) with moderate to severe TBI discharged from a Pennsylvania rehabilitation treatment facility. Extensive pre-injury sociodemographic, injury-severity, post-injury personal (cognitive, physical, affective), post-injury environmental (social, institutional, physical), and post-injury occupational performance (participation in self-care, productivity, leisure activities) data were gathered from hospital records and using in-person interviews. Interviews occurred at a mean time of 14 (range, 7-24) years post-injury. Hierarchical multiple regression analysis was used to investigate determinants of long-term occupational performance outcomes.

RESULTS

Pre-injury behavioural problems, male gender, post-injury cognitive and physical deficits, and lack of access to transportation were significant independent predictors of worse occupational performance outcomes.

CONCLUSIONS

The study supports the use of a comprehensive model for long-term outcomes after TBI where pre-injury characteristics and post-injury cognitive and physical characteristics account for the greatest proportion of explained variance.

Aging after spinal cord injury: A 30-year longitudinal study

BACKGROUND/OBJECTIVE

This longitudinal study investigated changes in life satisfaction, general health, activities, and adjustment over 3 decades among individuals with spinal cord injury (SCI).

PARTICIPANTS

The cohort of participants was identified from outpatient records of a large Midwestern United States university hospital. In 1973, 256 individuals completed an initial survey. There were 5 subsequent follow-up surveys, with the most recent being in 2002. Seventy-eight participants completed materials on all 6 occasions.

METHODS

The Life Situation Questionnaire was used to identify changes over the 30-year period in 6 areas of life satisfaction, self-rated adjustment (current and predicted), employment status, activities, and medical treatments.

ANALYSES

These analyses used data from 3 points in time, separated by approximately 15-year intervals. One-way analysis of variance with repeated measures was used to identify changes in outcomes between 1973, 1988, and 2002 for all continuous variables.

RESULTS

We found a mixed pattern of changes over the 30 years, with increases noted during the first 15-year period in sitting tolerance, educational and employment outcomes, satisfaction with employment, and adjustment. Although these changes tended to remain stable during the last 15 years, subtle declines were suggested in some areas, with clear declines noted in terms of diminished sitting tolerance, an increase in the number of physician visits, and decreased satisfaction with social life and sex life.

CONCLUSIONS

The results suggest that many positive changes occur within the first 2 decades after SCI, followed by a period of stability in some life areas, but decline with aging in some participation and health-related aspects of life.

Patients' perspective on the comprehensive preventive health evaluation in veterans with spinal cord injury

STUDY DESIGN

Survey research methods.

OBJECTIVES

To assess patient satisfaction with the annual comprehensive preventative health evaluation (CPHE) and to determine if the patient's needs were being met.

SETTING

Department of Veterans Affairs National Survey, United States.

METHODS

A total of 853 subjects with spinal cord injuries participated in a mailed survey regarding the annual CPHE. Subjects were asked about satisfaction with the examination, preferences on how the examination is conducted and whether their needs were being met with the examination.

RESULTS

In all, 76% of the subjects that responded to the survey had completed a CPHE within the previous year. Subjects cited getting their medication and supplies refilled and talking to the doctor as the top two reasons for completing the evaluation. Subjects indicated that they would most like to discuss their muscle strength and weakness, bladder care, chronic pain, digestion and bowel care issues, and equipment problems during their evaluation. The majority of subjects (81%) indicated that they were satisfied with the CPHE. Subjects that were satisfied with the CPHE were also more satisfied with other aspects of care as well.

CONCLUSION

The majority of respondents had completed a CPHE within the previous year. Most respondents cite health issues related to the spinal cord injury as areas they would most like to discuss during the evaluation. The majority of subjects were satisfied with the conduct of the CPHE.

Chronic pain in individuals with spinal cord injury: a survey and longitudinal study

STUDY DESIGN

Cross-sectional and longitudinal postal survey.

OBJECTIVES

To (1) compare the severity of pain in persons with spinal cord injury (SCI) to national norms, (2) examine the association between pain and measures of (a) psychological functioning, (b) community integration and (c) pain interference with daily activities, and (3) examine the change in the prevalence and intensity of pain over time.

SETTING

Community.

METHODS

A total of 147 adults with SCI were surveyed twice, 2-6 years apart. Main outcome measures included presence/absence of pain in general and at specific body sites, 0-10 numerical rating scale of average pain intensity, modified Brief Pain Inventory Pain Interference scale, SF-36 Bodily Pain scale, SF-36 Mental Health scale, Community Integration Questionnaire.

RESULTS

Pain was more severe, on average, in this sample of patients with SCI than it is in normative samples. The presence of pain was associated with trends towards poorer psychological functioning and social integration, and the intensity of pain was associated with interference with a number of important basic activities of daily living. Little systematic change was found in pain over a 2-6-year-period, although there was evidence that the prevalence of shoulder pain increases over time.

CONCLUSION

The current findings underscore the serious nature of pain in persons with SCI and provide additional support for the need to identify effective treatments for SCI-related pain.

Aging with spinal cord injury

The years after SCI may be associated with acceleration of the aging process because of diminished physiologic reserves and increased demands on functioning body systems. Clinicians with expertise in the treatment and prevention of SCI-specific secondary complications need to collaborate with gerontologists and primary care specialists and need to invest in the training of future physicians to ensure a continuum of accessible, cost-effective, and high-quality care that meets the changing needs of the SCI population. Managed care payers often do not adequately cover long-term disability needs to prevent secondary SCI-specific complications. In this era of increasing accountability, evidence-based clinical practice guidelines are needed to document scientific evidence and professional consensus to effectively diagnose, treat, and manage clinical conditions; to reduce unnecessary testing and procedures; and to improve patient outcomes. Longitudinal research is needed to minimize cohort effects that contribute to misinterpretation of cross-sectional findings as representative of long-term changes in health and functioning. However, longitudinal studies confound chronologic age, time since injury, and environmental change. Thus, time-sequential research, which controls for such confounding effects, is essential, as is research on the effects of gender,culture, and ethnicity. If we consider how much progress has been made over the past 50 years with respect to SCI mortality related to infectious disease, we can expect to achieve even greater progress against the effects of aging in the next 50 years. Recent developments in molecular biology regarding growth and neuro-trophic factors are bringing us closer to the goal of repairing the damaged spinal cord. The challenge remains for rehabilitation professionals to provide the most comprehensive and holistic approach to long-term follow-up, with an emphasis on health promotion and disease prevention, to postpone functional decline and enhance QOL.

Aging with a spinal cord injury: factors associated with the need for more help with activities of daily living

OBJECTIVES

To determine (1) the frequency of the need for more help with activities of daily living (ADLs), (2) the frequency of medical complications, and (3) the association between medical, injury-related, and sociodemographic factors and the need for more help with ADLs among those aging with spinal cord injury (SCI).

DESIGN

Cross-sectional survey.

SETTING

General community, international.

PARTICIPANTS

Volunteers (N=352) with SCI for more than 20 years.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

The need for more help with ADLs.

RESULTS

The need for more help with ADLs during the last 3 years was reported by 32.1% of participants. At least 1 medical complication was reported by 85%. Constipation (47.9%), diarrhea/bowel accidents (41.8%), and pressure ulcers (38.7%) were common. Constipation, pressure ulcers, female gender, and years postinjury were associated with needing more help with ADLs. Constipation and pressure ulcers were associated with a 97% and a 76% increase, respectively, in the likelihood of needing more help with ADLs during a 3-year time period. Female gender was associated with a 96% increased odds of needing more help with ADLs. There was a 42% increased odds of needing more help with ADLs per decade after SCI.

CONCLUSIONS

People aging with SCI are vulnerable to medical complications, and additional help is required to function. Knowledge of the effect of these factors, particularly the tetrad of constipation, pressure ulcers, female gender, and number of years postinjury, should increase awareness that more help with ADLs may be needed over time.

Perceived causes of change in function and quality of life for people with long duration spinal cord injury

OBJECTIVE

To determine those factors perceived to change or threaten function and quality of life among individuals with long duration spinal cord injury.

DESIGN

Retrospective self-report using telephone-administered questionnaire.

SETTING

Queensland, Australia.

SUBJECTS

Eighty-four community-resident persons with spinal cord injury.

MAIN OUTCOME MEASURES

Functional Independence Measure, Delighted-Terrible Scale, Perceived Causes of Change Inventory.

RESULTS

Pain and loss of strength were perceived to have caused change in function in 11.9% and 14.3% of participants respectively while these same factors were perceived to have caused change in quality of life in 19.0% and 17.9% of participants respectively. Even when measurable change had not occurred, pain and loss of strength were perceived threats to function in 45.2% and 44.0% of participants respectively, while these same factors were perceived threats to quality of life in 10.7% and 11.9% of individuals respectively. Emotional issues such as stress, depression, family functioning, financial status and employment were also perceived causes of change in quality of life.

CONCLUSIONS

The ability of participants to identify the perceived causes of change in function and quality of life may have implications for preventative health care if these individuals are encouraged to seek assistance when these factors first become apparent.

Psychiatric challenges in the first 6 years after traumatic brain injury: cross-sequential analyses of axis I disorders11No commercial party having a direct financial interest in the results of the research supporting this article has or will confer a benefit upon the authors(s) or upon any organization with which the author(s) is/are associated

OBJECTIVE

To examine the preinjury rates of Axis I disorders and the prospective rates within the first 6 years after traumatic brain injury (TBI).

DESIGN

Cross-sectional, longitudinal, and cross-sequential.

SETTING

Community-based research and training center.

PARTICIPANTS

Persons (N=188) who had sustained TBI within 4 years of enrollment into the project were interviewed at either 2 and 3 assessments. Each assessment was approximately 1 year apart. Several Axis I diagnoses were analyzed to detect cross-sectional differences (by age and time postinjury) and average individual changes over the multiple measurement time points.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders.

RESULTS

The odds ratios changed longitudinally within each subject, indicating a decreased probability of having an Axis I diagnosis over time. There were few cross-sectional differences in age; therefore, age at the time of injury had little impact on Axis I diagnoses. Cross-sectional time since injury was not associated with more psychiatric disorders, whereas cross-sectional preinjury history of psychiatric disorders was predictive of postinjury psychiatric disorders. After controlling for cross-sectional effects, the frequencies of Axis I disorders increased in depression, anxiety, and posttraumatic stress disorders in the first assessment postinjury and declined in subsequent assessments.

CONCLUSIONS

Cross-sequential analyses that control for cross-sectional and longitudinal differences produced a more complete description of psychiatric disorders after TBI.

Vieillissement chez les blessés médullaires

OBJECTIVE

Literature review of the data on aging with spinal cord injury.

METHOD

Interrogation on Medline using the following keywords: aging, spinal cord injuries, paraplegia, quadriplegia, mortality, morbidity, quality of life, survival, health status.

RESULTS

The expectation of life of the spinal cord injury patients improved even though it remains even lower than that of the general population. The effects of aging add to the specific complications which are numerous and alter almost every function. Respiratory complications became the first cause of death especially for tetraplegics. Urinary and cutaneous complications remain important as well as osteo-articular pathologies (particular upper limbs) whose consequences can be serious on the functional capacities. Studies on the quality of life show that adaptation to the handicap is done in a continuous way and a long time after the initial phase of rehabilitation. They underline the importance of professional resources, psychological reactions and previous experiences of the spinal cord injury patients in appreciating the quality of life after the traumatism.

CONCLUSION

The specificities of the aging of the spinal cord injury patients require to be well known and underline the importance and the necessity of an adequate and specific follow-up. On a more general plan, they imply a reflection on the strategies of initial rehabilitation, not to compromise the future of these spinal cord injury patients.

Aging, spinal cord injury, and quality of life: structural relationships

OBJECTIVE

To quantify relationships among 3 sets of factors: demographic factors, health and disability factors, and quality of life (QOL).

DESIGN

Part of a program of longitudinal research on aging and spinal cord injury (SCI) involving 3 populations: American, British, and Canadian. The present analysis uses data from the 1999 interval.

SETTING

The Canadian sample was derived from the member database of the Ontario and Manitoba divisions of the Canadian Paraplegic Association. The British sample was recruited from a national and a regional SCI center in England. The American sample was recruited through a hospital in Colorado.

PARTICIPANTS

A sample of 352 participants was assembled from 4 large, well-established databases. The sample included individuals who had incurred an SCI at least 20 years earlier, were admitted to rehabilitation within 1 year of injury, and were between the ages of 15 and 55 at the time of injury.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

A combination of self-completed questionnaires and interviews. Data included demographics, injury-related variables, health and disability-related factors, QOL, and perceptions about aging.

RESULTS

Using linear structural relationships modeling, we found that QOL was affected both directly and indirectly by age, health and disability problems, and perceptions of aging. Two surprising findings were as follows: those who experienced fewer disability-related problems were more likely to report a qualitative disadvantage in aging, and the younger members of the sample were more likely to report fatigue.

CONCLUSIONS

Fatigue is a concern because of the relationship of fatigue with perceived temporal disadvantage in aging, health problems, and disability problems. This finding highlights the need for clinical vigilance among those just beginning to experience the effects of aging.

Pain characteristics in patients admitted to hospital with complications after spinal cord injury

OBJECTIVES

To determine characteristics of pain, the relation between pain and mood, the effect of pain on activities, and the perceived difficulty in coping with pain in patients hospitalized for treatment of complications associated with spinal cord injury (SCI).

DESIGN

Cohort survey.

SETTING

Hospital inpatient unit in Australia.

PARTICIPANTS

Consecutive sample of patients (N=88) admitted to a hospital spinal injuries unit with complications after SCI. Two eligible patients declined to participate.

INTERVENTION

Face-to-face interview with questionnaire.

MAIN OUTCOME MEASURES

Pain severity, global self-rated health, mood (Kessler Mood Inventory), and interference with activities (Von Korff disability scale).

RESULTS

Sixty-six (75%) of the 88 subjects experienced pain, with an average time of onset +/- standard deviation of 8.02+/-12.4 years; 27% of those with pain described it as severe or excruciating. Subjects with pain were less likely to rate their global health as excellent or very good when compared with those who did not have pain (22% vs 44%, respectively). Patients with pain had significantly greater levels of psychologic distress than did people with SCI and no pain.

CONCLUSIONS

Pain is a common problem in people admitted to hospital with SCI for treatment of other complications. It has a significant impact on activities and is associated with a reduction in global self-rated health and higher levels of psychologic distress.

Chronic pain secondary to disability: a review

BACKGROUND

Until recently, very little has been written regarding chronic pain as a secondary problem in persons who already have a physical disability, despite the potential for pain to increase the negative impact of what may already be a very disabling condition. The purpose of this review is to summarize what is currently known concerning the nature and scope of chronic pain as a secondary condition to disability, specifically spinal cord injury, acquired amputations, cerebral palsy, multiple sclerosis, neuromuscular disease, and postpolio syndrome.

METHOD

What is known concerning the frequency, severity, impact, and treatment of pain in these specific conditions is reviewed, as are the factors that contribute to, or are associated with, adjustment to chronic pain in these disability groups. The authors conclude with several research questions that emerge from this knowledge, the answers to which will contribute to the long-term goal of the reduction of pain and suffering in persons with disabilities.

CONCLUSIONS

The existing literature clearly documents that many persons with disabilities experience chronic pain. Many questions remain unanswered regarding the scope, severity, and treatment of chronic pain in these groups.

Imaging in chronic spinal cord injury--indications and benefits

As most patients who have suffered spinal cord injury can now expect a normal life span, the late complications of these injuries are seen increasingly frequently. Regular surveillance of both the renal tract and the central nervous system (CNS) is important as the treatment of impending, potentially fatal complications can be implemented before damage has progressed too far. Renal tract complications are particularly dangerous as they are often clinically silent but regular surveillance to detect early deterioration in renal function, particularly from reversible causes such as reflux or obstruction can pre-empt problems. Follow-up protocols depend on the bladder management regime but most centres advocate regular ultrasound with less frequent isotope function studies. With the increasing ability to diagnose and treat the neurological complications, surveillance of the state of the spinal cord with MRI is also important and many centres now advocate checks every few years with sagittal midline T2W sections are sufficient unless changes are noted, when axial T1W sections can be added without significant examination time penalty. Imaging is critical in acute problems. In addition to suffering from the usual normal conditions, patients with spinal cord injury suffer others peculiar to, or particularly related to, the injury, which may be missed as their symptomatology is greatly altered by their paraplegic or quadriplegic status and they may often present as generally unwell but with no obvious cause. This review discusses the role of radiology in routine surveillance of the CNS and the renal tract as well as in assessing specific conditions such as deteriorating neurology or renal function, pain, spinal instability, pressure sores, ectopic ossification, muscular spasm, spinal instability, airway problems and elective operations on the renal tract.
