Aging with spinal cord injury

Neurogenic Aging After Spinal Cord Injury: Highlighting the Unique Characteristics of Aging After Spinal Cord Injury

Emanating from several decades of study into the effects of the aging process after spinal cord injury (SCI), "accelerated aging" has become a common expression as the SCI accelerates the onset of age-related pathologies. However, the aging process follows a distinct trajectory, characterized by unique patterns of decline that differ from those observed in the general population without SCI. Aging brings significant changes to muscles, bones, and hormones, impacting overall physical function. Muscle mass and strength begin to decrease with a reduction in muscle fibers and impaired repair mechanisms. Bones become susceptible to fractures as bone density decreases. Hormonal changes combined with decreased physical activity accelerate the reduction of muscle mass and increase in body fat. Muscle atrophy and skeletal muscle fiber type transformation occur rapidly and in a unique pattern after SCI. Bone loss develops more rapidly and results in an increased risk of fractures in body regions unique to individuals with SCI. Other factors, such as excessive adiposity, decreased testosterone and human growth hormone, and increased systemic inflammation, contribute to a higher risk of neuropathically driven obesity, dyslipidemia, glucose intolerance, insulin resistance, and increasing cardiovascular disease risk. Cardiorespiratory changes after SCI result in lower exercise heart rates, decreased oxygenation, and mitochondrial dysfunction. While it is important to acknowledge the accelerated aging processes after SCI, it is essential to recognize the distinct differences in the aging process between individuals without physical disabilities and those with SCI. These differences, influenced by neuropathology, indicate that it may be more accurate to describe the aging process in individuals with chronic SCI as neurogenic accelerated aging (NAA). Research should continue to address conditions associated with NAA and how to ameliorate the accelerated rate of premature age-related conditions. This review focuses on the NAA processes and the differences between them and the aging process in those without SCI. Recommendations are provided to help slow the development of premature aging conditions.

Prostitution in the shadow of life-long sexual abuse: Arab women's retrospective experiences

The present study uses the life-course and intersectionality perspectives to explore the meaning that aging Arab women attribute to their lived experiences of life-long sexual abuse in the shadow of engaging in prostitution. Interpretive phenomenological analysis was used to analyze the narratives of 10 older Arab women in Israel who were engaged in prostitution. Four themes emerged: experiencing childhood in the shadow of sexual abuse, becoming a prostitute, being entrapped in prostitution, and settling accounts with the native culture. Women aging in prostitution experience a harsh reality of abuse and loss. The present study points to multiple channels of abuse throughout the life course, from childhood until old age.

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

Background

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

Objectives

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

Methods

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

Results

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

Conclusion

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

Characterization and Health-Related Quality of Life in Older Adults With Disabilities According to Timing of Disability Onset

The current study examined characteristics of early-onset and late-onset disability in older adults and identified predictors of health-related quality of life (HRQoL). This is a secondary data analysis of the 2017 national survey in South Korea. Participants were 4,014 older adults with disabilities, who were divided into an early-onset group (n = 2,229) and late-onset group (n = 1,785). Data were analyzed using complex sample analyses. Difficulties during outdoor activity and transportation use, self-rated health, and stress were common predictors in both groups. Comorbidity was a significant predictor only in the early-onset group. Use of information technology devices, household income, and perceived social discrimination were significant predictors in the late-onset group. Characteristics and predictors of HRQoL were different between groups, despite sharing common characteristics. It is necessary to improve support systems and health care services for older adults with disabilities. [Journal of Gerontological Nursing, 48(3), 37-47.].

Trauma of Peripheral Innervation Impairs Content of Epidermal Langerhans Cells

Langerhans cells represent the first immune cells that sense the entry of external molecules and microorganisms at the epithelial level in the skin. In this pilot case-study, we evaluated Langerhans cells density and progression of epidermal atrophy in permanent spinal cord injury (SCI) patients suffering with either lower motor neuron lesions (LMNSCI) or upper motor neuron lesions (UMNSCI), both submitted to surface electrical stimulation. Skin biopsies harvested from both legs were analyzed before and after 2 years of home-based Functional Electrical Stimulation for denervated degenerating muscles (DDM) delivered at home (h-bFES) by large anatomically shaped surface electrodes placed on the skin of the anterior thigh in the cases of LMNSCI patients or by neuromuscular electrical stimulation (NMES) for innervated muscles in the cases of UMNSCI persons. Using quantitative histology, we analyzed epidermal thickness and flattening and content of Langerhans cells. Linear regression analyses show that epidermal atrophy worsens with increasing years of LMNSCI and that 2 years of skin electrostimulation reverses skin changes, producing a significant recovery of epidermis thickness, but not changes in Langerhans cells density. In UMNSCI, we did not observe any statistically significant changes of the epidermis and of its content of Langerhans cells, but while the epidermal thickness is similar to that of first year-LMNSCI, the content of Langerhans cells is almost twice, suggesting that the LMNSCI induces an early decrease of immunoprotection that lasts at least 10 years. All together, these are original clinically relevant results suggesting a possible immuno-repression in epidermis of the permanently denervated patients.

"Earth angels" and parking spots: qualitative perspectives on healthy aging with spinal cord injury

PURPOSE

People aging with spinal cord injury (SCI) can experience the premature onset of comorbid conditions, as well as the development and progression of secondary health conditions. The aim of this study was to understand the subjective experiences of persons aging with SCI in relation to their surrounding social and physical environments, including the impact of barriers and facilitators.Material/Methods: Eleven individuals who had an SCI for more than ten years and were 45 years or older participated in a semi-structured phone interview about their experiences with healthy aging, social participation, social supports, and community barriers.

RESULTS

Four main themes emerged in the qualitative data that captured the subjective experience of aging with SCI. These were: (1) Maintaining Physical Independence; (2) Importance of Resources and Special Equipment; (3) Planning Ahead; and (4) Finding Ways to Adapt.

CONCLUSIONS

The findings from this study highlight the importance of looking beyond individual factors to consider the social and environmental factors that support continued independence and participation in society as people living with long term SCI experience their aging process. Qualitative research that delves further into the dynamics behind this process is needed to fully anticipate the needs of this growing population.IMPLICATIONS FOR REHABILITATIONPeople aging with spinal cord injury (SCI) who are engaged in their social and physical environments have become increasingly adaptive when faced with accelerating and secondary comorbidities.Programs and facilities should ensure universal access to prevention and self-management programs that target physical activity and health habits when considered in the context of a patient's socio-environmental constraints and resources.Clinical healthcare providers need to engage with their patients to develop an early intervention approach to preserve functional capacity while navigating potential future health problems.Clinicians should act as advocates for ongoing policy changes that help promote an environment more inclusive towards people aging with SCI.

Reliability and Validity of the English Version of the AOSpine PROST (Patient Reported Outcome Spine Trauma)

STUDY DESIGN

Multicenter validation study.

OBJECTIVE

The aim of this study was to translate and adapt the AOSpine PROST (Patient Reported Outcome Spine Trauma) into English, and test its psychometric properties among North-American spine trauma patients.

SUMMARY OF BACKGROUND DATA

In the absence of an outcome instrument specifically designed and validated for traumatic spinal column injury patients, it is difficult to measure the effect size of various treatment options. The AOSpine Knowledge Forum Trauma initiated a project and developed the AOSpine PROST consisting of 19 items.

METHODS

Patients were recruited from two level-1 North-American trauma centers. For concurrent validity, next to AOSpine PROST also 36-item Short-Form Health Survey (SF-36) was filled out by patients. Patient characteristics were analyzed using descriptive statistics. Floor and ceiling effects as well as the number of inapplicable and missing questions were analyzed for content validity. Cronbach α and item-total correlation coefficients (ITCCs) were calculated for internal consistency. Spearman correlation tests were performed within AOSpine PROST items and in correlation to SF-36. Test-retest reliability was assessed using intraclass correlation coefficients (ICCs). Factor analysis was performed to explore any dimensions within AOSpine PROST.

RESULTS

The AOSpine PROST was translated adapted into English using established guidelines. Of 196 enrolled patients, 162 (82.7%) met the inclusion criteria and provided sufficient data. Content validity showed good results, and no floor and ceiling effects were seen. The internal consistency was excellent (Cronbach α = 0.97; ITCC 0.50-0.90) as well as test-retest reliability (ICC = 0.97). Spearman correlations were good (0.29-0.85). The strongest correlations of AOSpine PROST with SF-36 were seen with the physical components (0.69-0.82; P < 0.001). Factor analysis revealed two possible dimensions (Eigen values >1), explaining 75.7% of variance.

CONCLUSION

The English version of AOSpine PROST showed very good validity and reliability. It is considered as a valuable tool, and has the potential to contribute to the reduction of ongoing controversies in spine trauma care.

Colostomy and quality of life after spinal cord injury: systematic review

BACKGROUND

Spinal cord injury (SCI) has a significant impact on the quality of life (QoL) of affected patients. The aim of this review was to determine whether colostomy formation improves QoL in patients with SCI.

METHODS

The Cochrane Register, MEDLINE, Embase and CINAHL were searched using medical subject headings. The search was extended to the reference lists of identified studies, ClinicalTrials.gov and the WHO International Clinical Trials Registry. All clinical trials that included spinal injury and QoL, time spent on bowel care, and patient satisfaction with stoma were assessed.

RESULTS

A total of 15 studies were found (including 488 patients with a stoma), of which 13 were retrospective cross-sectional studies and two were case-control studies, one of which was prospective research. Nine of 11 studies focusing on QoL reported that patients' QoL was improved by the stoma, whereas the remaining two studies found no difference. Time spent on bowel care was significantly reduced in all 13 studies that considered this outcome, with patients reducing the average time spent on bowel care from more than 1 h to less than 15 min per day. All 12 studies assessing patient satisfaction with their stoma reported high patient satisfaction.

CONCLUSION

Stoma formation improves QoL, reduces time spent on bowel care, and increases independence. Stoma is an option that could be discussed and offered to patients with spinal cord injury.

Create a predictive model for neurogenic bladder patients: upper urinary tract damage predictive nomogram

Objective: To create a nomogram to evaluate the risk of upper urinary tract damage (UUTD) in patients with neurogenic bladder (NGB) Methods: A retrospective analysis was conducted on 301 patients with NGB who were admitted to certain hospitals. Data collected included clinical symptoms, patients' characteristics, laboratory parameters, imaging findings, and urodynamic parameters. The least absolute shrinkage and selection operator（LASSO）regression model was used to optimise the selection of predictors. Multivariate logistic regression analysis was performed to develop a UUTD risk predictive model. Validation was performed by bootstrap. Results: The predictors included in the nomogram included sex, duration of disease, history of UTI, bladder compliance, and fecal incontinence. The model presented good discrimination with a C-index value of 0.796 (95% confidence interval: 0.74896-0.84304) and good calibration. The C-index value of the interval validation was 0.7872112. The results of decision curve analysis (DCA) demonstrated that the UUTD-risk predictive nomogram was clinically useful. Conclusion: The nomogram incorporating the sex, duration of disease, history of UTI, bladder compliance, and fecal incontinence could be an important tool of UUTD risk prediction in NGB patients.

Ageing, Disability, and Spinal Cord Injury: Some Issues of Analysis

Spinal cord injury is a disabling disorder, worldwide spread, with important consequences on functioning and health conditions and impacts on physical, psychological, and social well-being. The consequences are related to the lesion itself and to other complications related to the lesion. In the last decades, there have been an increasing of the mean ages of onset and also an increase in life expectancy after the lesion. So, differently from the past, people with spinal cord injury can age after the lesion. Taking into account the need to share data and information about specific disabling conditions and their relationship with ageing, this paper aims to discuss some issues from recent literature on the relationship between aging and disability in the spinal cord injury, according to a narrative review approach. A narrative review of the literature on ageing and spinal cord injury was undertaken. Search was based on the following electronic databases: PubMed/Medline and Ovid/PsychINFO. A combination of the following keywords was used: (1) “ageing” or “aging” and (2) “spinal cord injury” or “spinal cord lesion” and (3) disability. Data on consequences of the lesion in the life of aging people, secondary health conditions, life expectancy, participation, and quality of life are discussed. Then, a brief discussion of clinical issues and the role of interventions aimed to promote wellbeing, health, quality of life, and participation of people with spinal cord injury is proposed.

Methodological and clinical implications of a three-in-one Russian doll design for tracking health trajectories and improving health and function through innovative exercise treatments in adults with disability

BACKGROUND

Hybrid research designs targeting adults with neurologic disability are critical for improving the efficiency of models that can identify, track and intervene on identified health issues.

METHODS

Our Russian doll framework encompasses three study phases. Phase 1 involves prospectively following a cohort of participants with disability to examine the relationships between rates of health and functional deficits (e.g., pain, fatigue, deconditioning), functional measures (e.g., cardiorespiratory endurance, strength, balance), and environmental and sociocultural factors. In Phase 2, eligible participants with neurologic disability from Phase 1 (in our example, individuals with multiple sclerosis) are screened and randomized to a clinical exercise efficacy trial. In Phase 3, study participants are enrolled in a home-based teleexercise trial to test the feasibility and replicability of delivering the clinical exercise study in the home.

DISCUSSION

This unique three-in-one Russian doll framework serves as a foundation for informing and guiding researchers and clinicians in treating certain health and functional deficits in people with neurologic disability using exercise as a primary treatment modality in both the clinical and home settings. It offers a unique perspective for understanding the critical issues of functioning, health maintenance and quality of life for people with neurologic disability across a longitudinal framework.

TRIAL REGISTRATION

Study 2 ClinicalTrials.gov identifier NCT02533882 (retroactively registered 03/06/2015). Study 3 ClinicalTrials.gov identifier NCT03108950 (retroactively registered 04/05/2017).

"To Work Just Like Anyone Else"-A Narrative from a Man Aging with Spinal Cord Injury

People aging with spinal cord injury (SCI) develop medical problems commonly associated with the aging process at a younger age than the general population. However, research about how the life story changes and how meaning will be experienced in occupations is lacking. The aim was to describe and offer an explanation of how a man experienced meaning in everyday occupations while aging with an SCI. Four narrative interviews were performed over a four-year period, with a man in his fifties, who lived with SCI for 39 years. The narrative analysis generated an overall plot, named “To Work Just Like Anyone Else,” and gives a picture of his experiences, thoughts, and reflections about meaning in occupations, from when he became injured to the present, and in relation to his future. His life story is characterized by secondary health complications, and his experiences of negotiating with the aging body and making choices to continue working. Further, how occupational risk factors, e.g., imbalance, alienation, and deprivation, occur as a result of lack of rehabilitation and support from social systems is addressed. Future research should explore how rehabilitation and social systems can support people aging with SCI to experience meaning in everyday occupations and to have balance in everyday life.

Effects of Respiratory Training on Heart Rate Variability and Baroreflex Sensitivity in Individuals With Chronic Spinal Cord Injury

OBJECTIVE

To evaluate the effects of pressure threshold respiratory training (RT) on heart rate variability and baroreflex sensitivity in persons with chronic spinal cord injury (SCI).

DESIGN

Before-after intervention case-controlled clinical study.

SETTING

SCI research center and outpatient rehabilitation unit.

PARTICIPANTS

Participants (N=44) consisted of persons with chronic SCI ranging from C2 to T11 who participated in RT (n=24), and untrained control subjects with chronic SCI ranging from C2 to T9 (n=20).

INTERVENTIONS

A total of 21±2 RT sessions performed 5 days a week during a 4-week period using a combination of pressure threshold inspiratory and expiratory devices.

MAIN OUTCOME MEASURES

Forced vital capacity (FVC), forced expiratory volume in 1 second (FEV₁), and beat-to-beat arterial blood pressure and heart rate changes during the 5-second-long maximum expiratory pressure maneuver (5s MEP) and the sit-up orthostatic stress test, acquired before and after the RT program.

RESULTS

In contrast to the untrained controls, individuals in the RT group experienced significantly increased FVC and FEV₁ (both P<.01) in association with improved quality of sleep, cough, and speech. Sympathetically (phase II) and parasympathetically (phase IV) mediated baroreflex sensitivity both significantly (P<.05) increased during the 5s MEP. During the orthostatic stress test, improved autonomic control over heart rate was associated with significantly increased sympathetic and parasympathetic modulation (low- and high-frequency change: P<.01 and P<.05, respectively).

CONCLUSIONS

Inspiratory-expiratory pressure threshold RT is a promising technique to positively affect both respiratory and cardiovascular dysregulation observed in persons with chronic SCI.

Long-Term Complications of the Neurogenic Bladder

It is widely accepted that neurogenic lower urinary tract dysfunction, when left untreated, has a natural history that has a potential for causing deterioration of renal function over time. However, certain patient profiles are at risk for this and other complications. This can be linked to their underlying neurologic disease process. Identifying risk profiles allows the provider to determine what surveillance strategies might be adopted. Risk factors for upper urinary tract deterioration include loss of bladder compliance, repeated bouts of pyelonephritis, and chronic indwelling catheterization. Other long-term complications include nephrolithiasis, refractory urinary incontinence, and malignancy.

Respiratory problems and management in people with spinal cord injury

Spinal cord injury (SCI) is characterised by profound respiratory compromise secondary to the level of loss of motor, sensory and autonomic control associated with the injury. This review aims to detail these anatomical and physiological changes after SCI, and outline their impact on respiratory function. Injury-related impairments in strength substantially alter pulmonary mechanics, which in turn affect respiratory management and care. Options for treatments must therefore be considered in light of these limitations.

KEY POINTS

Respiratory impairment following spinal cord injury (SCI) is more severe in high cervical injuries, and is characterised by low lung volumes and a weak cough secondary to respiratory muscle weakness.Autonomic dysfunction and early-onset sleep disordered breathing compound this respiratory compromise.The mainstays of management following acute high cervical SCI are tracheostomy and ventilation, with noninvasive ventilation and assisted coughing techniques being important in lower cervical and thoracic level injuries.Prompt investigation to ascertain the extent of the SCI and associated injuries, and appropriate subsequent management are important to improve outcomes.

EDUCATIONAL AIMS

To describe the anatomical and physiological changes after SCI and their impact on respiratory function.To describe the changes in respiratory mechanics seen in cervical SCI and how these changes affect treatments.To discuss the relationship between injury level and respiratory compromise following SCI, and describe those at increased risk of respiratory complications.To present the current treatment options available and their supporting evidence.

Participation in activities and secondary health complications among persons aging with traumatic spinal cord injury

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

To describe participation in activities and explore the relationship with secondary complications among persons aging with a traumatic spinal cord injury (SCI).

SETTING

A regional SCI outpatient center in Sweden.

METHODS

Data were collected through a phone survey, which included 10 activities from the instrument PARTS/M-v3 (PARTicipation Survey/Mobility version-3) together with data from the participants' medical records. Cross-tabulation and χ² were used for data analysis.

RESULTS

In this study, 121 persons matched the inclusion criteria and the final study sample comprised 73 participants (60% response rate): 55 men and 18 women. Mean age was 63.7±9.4 years, and mean time since injury was 36.3±9.2 years. Regardless of duration of SCI, all 73 participated in dressing, bathing and leisure activities. Women reported better health than men. Particularly for those who lived 36-55 years after injury; increasing pain, fatigue, spasticity and decreased muscle strength were negatively affecting participation in activities, especially exercise and active recreation. Additionally, a need to save strength/energy was also a reason for not participating in the activities. Perceived future support and concerns in relation to personal assistance, assistive devices and rehabilitation was also reported.

CONCLUSION

Increasing secondary health complications and a need to save strength/energy influenced participation in activities. Laws and/or governmental policies regarding personal assistance and assistive devices did not always support participation in activities. Interventions should aim to create a balance among activities in everyday life.

The feasibility study of extradural nerve anastomosis technique for canine bladder reinnervation after spinal cord injury

OBJECTIVE

Intradural nerve anastomosis for bladder innervation has been demonstrated to be useful. However, its clinical application remains limited because of the complex surgery, its complications and extensive bony destruction. The purpose of the current study was to demonstrate the feasibility of extradural spinal root anastomosis for bladder innervation in canines.

METHODS

Ten beagle dogs were used. The length of the extradural segment of the nerve root, upper nerve root outlet (the point at which it emerges from the spinal dura mater) to S2 (dS2), the S3 (dS3) nerve root outlet distance, and the diameters of the extradural spinal roots were measured. The numbers of nerve fibers from L6 to S3 ventral roots were calculated using immunohistochemical staining.

RESULTS

The extradural spinal roots could be divided into a ventral root (VR) and a dorsal root (DR) before the ganglionic enlargement of the dorsal root, and the extradural motor nerve roots situate ventrally to their corresponding sensory nerve roots. The extradural nerve root lengths of S1 and parts of L7 were longer than the corresponding dS2. The numbers of nerve and motor nerve fibers, and the diameters of extradural nerve roots, were gradually descending from L6 to S3.

CONCLUSION

The S1 VRs and parts of the L7 VRs can be extradurally anastomosed to the S2 nerves without tension. A nerve graft was needed for extradural anastomosis of L6 VRs and parts of L7 VRs to S2 VRs. This study demonstrated the feasibility of extradural spinal nerve anastomosis for treating neurogenic bladder in canines.

The selection of core International Classification of Functioning, Disability, and Health (ICF) categories for patient-reported outcome measurement in spine trauma patients-results of an international consensus process

BACKGROUND CONTEXT

There is no outcome instrument specifically designed and validated for spine trauma patients without complete paralysis, which makes it difficult to compare outcomes of different treatments of the spinal column injury within and between studies.

PURPOSE

The paper aimed to report on the evidence-based consensus process that resulted in the selection of core International Classification of Functioning, Disability, and Health (ICF) categories, as well as the response scale for use in a universal patient-reported outcome measure for patients with traumatic spinal column injury.

STUDY DESIGN/SETTING

The study used a formal decision-making and consensus process.

PATIENT SAMPLE

The sample includes patients with a primary diagnosis of traumatic spinal column injury, excluding completely paralyzed and polytrauma patients.

OUTCOME MEASURES

The wide array of function and health status of patients with traumatic spinal column injury was explored through the identification of all potentially meaningful ICF categories.

METHODS

A formal decision-making and consensus process integrated evidence from four preparatory studies. Three studies aimed to identify relevant ICF categories from three different perspectives. The research perspective was covered by a systematic literature review identifying outcome measures focusing on the functioning and health of spine trauma patients. The expert perspective was explored through an international web-based survey among spine surgeons from the five AOSpine International world regions. The patient perspective was investigated in an international empirical study. A fourth study investigated various response scales for their potential use in the future universal outcome instrument. This work was supported by AOSpine. AOSpine is a clinical division of the AO Foundation, an independent medically guided non-profit organization. The AOSpine Knowledge Forums are pathology-focused working groups acting on behalf of AOSpine in their domain of scientific expertise.

RESULTS

Combining the results of the preparatory studies, the list of ICF categories presented at the consensus conference included 159 different ICF categories. Based on voting and discussion, 11 experts from 6 countries selected a total of 25 ICF categories as core categories for patient-reported outcome measurement in adult traumatic spinal column injury patients (9 body functions, 14 activities and participation, and 2 environmental factors). The experts also agreed to use the Numeric Rating Scale 0-100 as response scale in the future universal outcome instrument.

CONCLUSIONS

A formal consensus process integrating evidence and expert opinion led to a set of 25 core ICF categories for patient-reported outcome measurement in adult traumatic spinal column injury patients, as well as the response scale for use in the future universal disease-specific outcome instrument. The adopted core ICF categories could also serve as a benchmark for assessing the content validity of existing and future outcome instruments used in this specific patient population.

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.

Neural reconstruction methods of restoring bladder function

During the past century, diverse studies have focused on the development of surgical strategies to restore function of a decentralized bladder after spinal cord or spinal root injury via repair of the original roots or by transferring new axonal sources. The techniques included end-to-end sacral root repairs, transfer of roots from other spinal segments to sacral roots, transfer of intercostal nerves to sacral roots, transfer of various somatic nerves to the pelvic or pudendal nerve, direct reinnervation of the detrusor muscle, or creation of an artificial reflex pathway between the skin and the bladder via the central nervous system. All of these surgical techniques have demonstrated specific strengths and limitations. The findings made to date already indicate appropriate patient populations for each procedure, but a comprehensive assessment of the effectiveness of each technique to restore urinary function after bladder decentralization is required to guide future research and potential clinical application.

Toward developing a specific outcome instrument for spine trauma: an empirical cross-sectional multicenter ICF-based study by AOSpine Knowledge Forum Trauma

STUDY DESIGN

Empirical cross-sectional multicenter study.

OBJECTIVE

To identify the most commonly experienced problems by patients with traumatic spinal column injuries, excluding patients with complete paralysis.

SUMMARY OF BACKGROUND DATA

There is no disease or condition-specific outcome instrument available that is designed or validated for patients with spine trauma, contributing to the present lack of consensus and ongoing controversies in the optimal treatment and evaluation of many types of spine injuries. Therefore, AOSpine Knowledge Forum Trauma started a project to develop such an instrument using the International Classification of Functioning, Disability and Health (ICF) as its basis.

METHODS

Patients with traumatic spinal column injuries, within 13 months after discharge from hospital were recruited from 9 trauma centers in 7 countries, representing 4 AOSpine International world regions. Health professionals collected the data using the general ICF Checklist. The responses were analyzed using frequency analysis. Possible differences between the world regions and also between the subgroups of potential modifiers were analyzed using descriptive statistics and Fisher exact test.

RESULTS

In total, 187 patients were enrolled. A total of 38 (29.7%) ICF categories were identified as relevant for at least 20% of the patients. Categories experienced as a difficulty/impairment were most frequently related to activities and participation (n = 15), followed by body functions (n = 6), and body structures (n = 5). Furthermore, 12 environmental factors were considered to be a facilitator in at least 20% of the patients.

CONCLUSION

Of 128 ICF categories of the general ICF Checklist, 38 ICF categories were identified as relevant. Loss of functioning and limitations in daily living seem to be more relevant for patients with traumatic spinal column injuries rather than pain during this time frame. This study creates an evidence base to define a core set of ICF categories for outcome measurement in adult spine trauma patients.

Mortality and longevity after a spinal cord injury: systematic review and meta-analysis

BACKGROUND/AIMS

Mortality and longevity studies of spinal cord injury (SCI) are essential for informing healthcare systems and policies. This review evaluates the current evidence among people with SCIs worldwide in relation to the WHO region and country income level; demographic and lesion characteristics; and in comparison with the general population.

METHODS

A systematic review of relevant databases for original studies. Pooled estimates were derived using random effects meta-analysis, restricted to traumatic SCI.

RESULTS

Seventy-four studies were included. In-hospital mortality varied, with pooled estimates of 24.1% (95% confidence interval (CI) 14.1-38.0), 7.6% (95% CI 6.3-9.0), 7.0% (95% CI 1.5-27.4), and 2.1% (95% CI 0.9-5.0) in the WHO regions of Africa, the Americas, Europe and Western Pacific. The combined estimate for low- and middle-income countries was nearly three times higher than for high-income countries. Pooled estimates of first-year survival were 86.5% (95% CI 75.3-93.1), 95.6% (95% CI 81.0-99.1), and 94.0% (95% CI 93.3-94.6) in the Americas, Europe and Western Pacific. Pooled estimates of standardized mortality ratios in tetraplegics were 2.53 (2.00-3.21) and 2.07 (1.47-2.92) in paraplegics.

CONCLUSION

This study found substantial variation in mortality and longevity within the SCI population, compared to the general population, and between WHO regions and country income level. Improved standardization and quality of reporting is needed to improve inferences regarding the extent to which mortality outcomes following an SCI are related to healthcare systems, services and policies.

Evidence-Based Strategies for Preserving Mobility for Elderly and Aging Manual Wheelchair Users

Elderly and aging manual wheelchair (MWC) users have increased risk for accelerated loss of function and mobility that greatly limits independence and affects quality of life. This review paper addresses important issues for preserving function and mobility for elderly and aging individuals who use a MWC by presenting the current available evidence and recommendations. These include recommendations for maximizing function, by decreasing pain, improving the ability to self-propel, and prolonging mobility and endurance through ergonomics, individualized wheelchair selection and configuration, and adaptations for increasing the capacity to handle the daily mobility demands through training, strengthening, and exercise. Each recommendation is supported by current research in each relevant area.

A multi-centred audit of secondary spinal assessments in a trauma setting: are we ATLS compliant?

PURPOSE

The global incidence of spinal cord injuries varies with the developed world having improved survival and 1 year mortality in a poly-trauma setting. This improved survival has been estimated at 20 % in a recent Cochrane review of Advanced Trauma Life Support (ATLS).The aim of this audit is to evaluate the management of patients with suspected spinal cord injury by the trauma and orthopaedic team in three centres in South Wales.

METHODS

A retrospective case note review of the secondary survey was performed. Inclusion criteria were patients 18 years and above, with poly-trauma and presenting to Accident and Emergency department at the treating hospital. We used ATLS guidelines as an audit tool and reviewed the documentation of key components of the secondary assessment.

RESULTS

Forty-nine patients were included (29 males, 20 females) with an average age of 53.7 years (19-92 years). We found that completion of all components of the secondary survey for spinal injury was poor, 29 % receiving a digital per rectal examination despite suspected spinal injury. Paralysis level was not documented in 20.4 % of patients. Medical Research Council grade was only documented in 24.5 % although was assessed in 73.5 %. The secondary survey took place after 2 h in 54.6 % of patients.

CONCLUSION

We found that the documentation of the performance of a secondary survey was poor. We found that most patients included in this study are not currently meeting the minimal standard suggested by the ATLS guidelines.

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.

Comparison of expression of inflammatory cytokines in the spinal cord between young adult and aged beagle dogs

Aging is an inevitable process that occurs in the whole body system accompanying with many functional and morphological changes. Inflammation is known as one of age-related factors, and inflammatory changes could enhance mortality risk. In this study, we compared immunoreactivities of inflammatory cytokines, such as interleukin (IL)-2 (a pro-inflammatory cytokine), its receptor (IL-2R), IL-4 (an anti-inflammatory cytokine), and its receptor (IL-4R) in the cervical and lumbar spinal cord of young adult (2-3 years old) and aged (10-12 years old) beagle dogs using immunohistochemistry and western blotting. IL-2 and IL-2R-immunoreactive nerve cells were found throughout the gray matter of the cervical and lumbar spinal cord of young adult and aged dogs. In the spinal cord neurons of the aged dog, immunoreactivity and protein levels were apparently increased compared with those in the young adult dog. Change patterns of IL-4- and IL-4R-immunoreactive cells and their protein levels were also similar to those in IL-2 and IL-2R; however, IL-4 and IL-4R immunoreactivity in the periphery of the neuronal cytoplasm in the aged dog was much stronger than that in the young adult dog. These results indicate that the increase of inflammatory cytokines and their receptors in the aged spinal cord might be related to maintaining a balance of inflammatory reaction in the spinal cord during normal aging.

Effects of disability-associated low energy expenditure deconditioning syndrome

People with neuromuscular disabilities have high rates of sedentary behavior predisposing them to severe deconditioning and significant health risk. We describe this as disability-associated low energy expenditure deconditioning syndrome and propose new approaches for promoting light-to-moderate intensity physical activity in people with disabilities.

The changing field of rehabilitation: optimizing spontaneous regeneration and functional recovery

For neurorehabilitation of patients with spinal cord injury (SCI), the traditional emphasis on social adaptation is being expanded to include strategies that promote plasticity and regeneration in the central nervous system. Such strategies are needed to optimize recovery of neurological function. For example, the known dependence of most cellular processes on physical activity has led to the novel concept that activity is important in neural repair. This hypothesis has given rise to activity-based restoration therapies (ABRT), which aim to optimize neural activity in the damaged spinal cord, particularly below the injury level. Here, we review the basic science and clinical evidence supporting the lifelong use of ABRT for recovery from spinal cord injury. We define and describe ABRT, and discuss its components, its clinical applications, its relationship to medical management of spinal cord injury, and the potential influences of medications on recovery. We also discuss the health benefits of ABRT under physiological and pathological conditions. We stress that lifelong ABRT is required to optimize return of function and to allow patients to benefit from any "cures" that will be discovered.

A conceptual model for identifying, preventing, and managing secondary conditions in people with disabilities

Secondary conditions are considered a direct consequence of having a disability, and many are presumed to be preventable. Although a few researchers have noted that people with disabilities are exposed to several secondary conditions, including pain, fatigue, depression, and obesity, what is lacking in the literature is a conceptual framework for understanding the antecedents, risk factors, and consequences of secondary conditions. To move the rehabilitation and public health professions toward a more unified approach to understanding and managing secondary conditions as well as distinguishing them from chronic and associated conditions, this article proposes a set of criteria for defining secondary conditions and a conceptual model that considers the potential factors associated with their onset, impact, severity, and management.

Mortality in patients with traumatic spinal cord injury: descriptive analysis of 62 deceased subjects

STUDY DESIGN

Retrospective study.

OBJECTIVE

To investigate the causes of death in patients who were ≤ 50 years at the time of traumatic spinal cord injury (tSCI).

SETTING

Convenience sample of a tertiary rehabilitation center.

METHODS

All deceased patients with tSCI who survived a minimum of 10 years post-injury, were included. In addition, causes of death were compared between subjects surviving <10 years and ≥ 10 years. Neurological assessments were performed according to the American Spinal Injury Association scale. Data on causes of death were analyzed using the ICD-10 classifications. Differences were calculated using the Mann-Whitney and chi-square tests.

RESULTS

A total of 100 patients, with 38 and 62 surviving <10 and ≥ 10 years, respectively, were included. No significant differences in causes of death were identified between these two groups. In patients surviving ≥ 10 years, paraplegia was associated with a higher life expectancy compared with tetraplegia, 34 and 25 years (p = 0.008), respectively, and the leading causes of death were septicemia (n = 14), ischemic heart disease (n = 10), neoplasms (n = 9), cerebrovascular diseases (n = 5), and other forms of heart diseases (n = 5). Septicemia, influenza/pneumonia, and suicide were the leading causes of death in tetraplegics, whereas ischemic heart disease, neoplasms, and septicemia were the leading causes of death in paraplegia.

CONCLUSION

Our monocentric study showed that in 62 deceased patients with SCI, the leading causes of death were septicemia, cardiovascular diseases, neoplasms, and cerebrovascular diseases. In addition, no significant differences were identified between causes of death among patients surviving <10 years and ≥ 10 years post-injury.

Imaging the spine for tumour and trauma--a national audit of practice in Irish hospitals

BACKGROUND AND PURPOSE

The provision of appropriate spinal imaging in cases of acute injury as a consequence of trauma or tumour is becoming ever more challenging. This study assessed the use of multimodal radiological investigations in the management of spinal cord compression as a result of trauma and metastatic cancer in all major Irish hospitals.

METHODS

We conducted a questionnaire of thirty four hospitals in an effort to assess the provision of these services to patients with possible spinal cord compromise. In all public hospitals the Emergency Department and/or the Orthopaedic Registrars were contacted and asked a series of questions relating to spinal clearance, spinal clearance protocols, CT and MRI scanning facilities and on site orthopaedic services.

RESULTS

All centres participated in the study. 67.64% of centres routinely used a protocol in spinal clearance. In 87% of hospitals the Emergency department were responsible for clearing the spine. 85.3% of hospitals had CT availability during normal working hours (9-5) dropping to 47% availability after hours. MRI was available in 50% of hospitals, with surprisingly just two centres providing out of hours MRI imaging services.

CONCLUSION

The provision of radiological services in the management of suspected spinal injuries in Irish hospitals is inadequate in comparison to international best practice. This is most marked in relation to CT and MRI.

Earthquake-related versus non-earthquake-related injuries in spinal injury patients: differentiation with multidetector computed tomography

Introduction

In recent years, several massive earthquakes have occurred across the globe. Multidetector computed tomography (MDCT) is reliable in detecting spinal injuries. The purpose of this study was to compare the features of spinal injuries resulting from the Sichuan earthquake with those of non-earthquake-related spinal trauma using MDCT.

Methods

Features of spinal injuries of 223 Sichuan earthquake-exposed patients and 223 non-earthquake-related spinal injury patients were retrospectively compared using MDCT. The date of non-earthquake-related spinal injury patients was collected from 1 May 2009 to 22 July 2009 to avoid the confounding effects of seasonal activity and clothing. We focused on anatomic sites, injury types and neurologic deficits related to spinal injuries. Major injuries were classified according to the grid 3-3-3 scheme of the Magerl (AO) classification system.

Results

A total of 185 patients (82.96%) in the earthquake-exposed cohort experienced crush injuries. In the earthquake and control groups, 65 and 92 patients, respectively, had neurologic deficits. The anatomic distribution of these two cohorts was significantly different (P < 0.001). Cervical spinal injuries were more common in the control group (risk ratio (RR) = 2.12, P < 0.001), whereas lumbar spinal injuries were more common in the earthquake-related spinal injuries group (277 of 501 injured vertebrae; 55.29%). The major types of injuries were significantly different between these cohorts (P = 0.002). Magerl AO type A lesions composed most of the lesions seen in both of these cohorts. Type B lesions were more frequently seen in earthquake-related spinal injuries (RR = 1.27), while we observed type C lesions more frequently in subjects with non-earthquake-related spinal injuries (RR = 1.98, P = 0.0029).

Conclusions

Spinal injuries sustained in the Sichuan earthquake were located mainly in the lumbar spine, with a peak prevalence of type A lesions and a high occurrence of neurologic deficits. The anatomic distribution and type of spinal injuries that varied between earthquake-related and non-earthquake-related spinal injury groups were perhaps due to the different mechanism of injury.

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.

Age, gender, and side differences of cutaneous electrical perceptual threshold testing in an able-bodied population

OBJECTIVE

To investigate age, gender, and left-right differences in cutaneous electrical perceptual threshold (EPT) testing in an able-bodied, Australian sample.

STUDY DESIGN

Prospective experimental.

SETTING

Hospital-based spinal cord injuries unit.

METHODS

Cutaneous electrical stimulation of the 28 dermatomes at ASIA sensory key points (C2-S4/S5) was performed on 29 female and 16 male healthy volunteers aged 21 to 76 years. Mean EPTs for each dermatome were compared (repeated measures ANOVA) for left-right, gender-related, and age-related (</ >50 years of age) differences.

RESULTS

There was no group difference between sides (repeated measures ANOVA, P = 0.934). Women across all ages had lower group mean EPTs than men (P < 0.0001). Women younger than age 50 years had lower mean EPTs than those older than age 50 years (P = 0.008). There was no group difference between younger and older men (P = 0.371). Analysis of individual dermatomes revealed no significant differences in thoracic dermatomes between genders or age groups, contrary to the limb dermatomes.

CONCLUSION

There were gender differences in EPT values across all ages. Women had higher EPTs as they advanced in age, but this was less clear in men. There was considerable somatotopic variability in EPTs, especially in the lower limbs. If EPT testing is to be applied to detect subclinical changes within a dermatome, establishment of age- and gender-specific somatotopic normograms is a prerequisite.

The Relationship of Chronological Age, Age at Injury, and Duration of Injury to Employment Status in Individuals with Spinal Cord Injury

Employment status following spinal cord injury (SCI) has important implications for financial and psychosocial well-being. Several age-related variables-in particular chronological age, duration of SCI, and age at SCI onset-have been identified as being associated with employment among individuals with SCI. Cross-sectional investigations of this topic are complicated by methodological and statistical issues associated with aging and disability. The purpose of the current study was to examine the associations between three aging variables and employment status in individuals with SCI through a series of regression analyses. Six hundred twenty individuals with SCI completed a survey that included measures of demographic characteristics, pain, psychological functioning, physical functioning, fatigue, and sleep. The results indicated that chronological age and age at SCI onset were significant predictors of employment status. A significantly greater proportion of individuals aged 45-54 were employed compared to those aged 55-64 even after controlling for biopsychosocial variables. Additionally, there was a negative linear relationship between percent employed and age at SCI onset, and this relationship was not accounted for by the biopsychosocial variables. The analyses used in this study provide one method by which to disentangle the effects of different age-related variables on important SCI outcomes in cross-sectional research. Continued research in this area is needed to better understand age-related effects on employment status, which could be used to help maximize the quality of life in individuals with SCI.

Sleep problems in individuals with spinal cord injury: frequency and age effects

OBJECTIVES

The two objectives of this study were (a) to replicate the previous finding of more severe sleep difficulties in a sample of individuals with spinal cord injury (SCI) compared with normative samples, and (b) to examine the associations between aging variables (specifically, chronological age, duration of SCI, age at SCI onset) and the severity of sleep difficulties.

DESIGN

Cross-sectional survey.

RESEARCH METHOD

A survey was administered to 620 individuals with SCI that included measures of demographic characteristics and sleep difficulties.

RESULTS

The findings indicated that sleep problems are more common in individuals with SCI than in normative samples. In addition, younger participants in our sample reported more sleep problems than did older participants. Duration of SCI and age at onset, however, were not significantly associated with sleep difficulties.

CONCLUSION

The analyses used in this study provide a model for examining age effects using concurrent survey data that may be useful for other investigators interested in studying the associations between age-related variables and important health-related domains.

Fatigue in children with neurologic impairments

Children with neuromuscular illness are at high risk for fatigue. This symptom, although difficult to decipher, can contribute significantly to the child's disability. It is, therefore, imperative to consider fatigue in the management of children with special health care needs. Currently, the literature on chronic fatigue in children is sparse and so more investigative work must be done to understand and manage this condition.

Epidemiology of spine trauma in an Irish regional trauma unit: a 4-year study

Currently there is a lack of information on the full spectrum of spine trauma presenting to medical services in a defined geographic area. This study analyses the aetiology and demographics of a cohort of spine trauma in the West of Ireland. A regional trauma unit has been investigated for a 51-month period. Two hundred and eighty-five cases admitted with spine trauma were documented. The annual incidence of traumatic spinal injury was 19.54 cases/100,000 persons per year. Falls and low-energy trauma are shown to constitute a significant proportion of all cases (60.35%). Injury at greater than one level is frequently present. The highest peak of injury occurred in the 20-24-year-old age group (11.58%). A second peak occurred at 75-79 years of age (7.37%). The commonest cause of neurological injury was falls (n=9; 64.3%). This spine trauma register has provided valuable insights into the patterns of injury encountered in spine trauma patients in this region. It may act as a blueprint for a national spine trauma register and highlights the importance of patient education and injury prevention strategies.

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.

Symptom burden in persons with spinal cord injury

OBJECTIVE

To determine (1) the frequency, severity, and reported course of 7 symptoms in persons with spinal cord injury (SCI) and (2) the association between these symptoms and patient functioning.

DESIGN

Postal survey.

SETTING

Community.

INTERVENTION

A survey that included measures of the frequency, severity, and recalled course of pain, fatigue, numbness, weakness, shortness of breath, vision loss, and memory loss, as well as a measure of community integration and psychologic functioning was mailed to a sample of persons with SCI. One hundred forty-seven usable surveys were returned (response rate, 43% of surveys mailed).

MAIN OUTCOME MEASURES

The frequency and average severity of each symptom was computed, and the frequencies of each type of reported course were noted. Analyses estimated the associations among the symptoms, and between symptom severity and measures of patient functioning.

RESULTS

The most common symptoms were pain, weakness, fatigue, and numbness. All symptoms were reported to remain the same or to get worse more often than they were reported to improve once they began. Pain, weakness, fatigue, and memory loss were the symptoms most closely associated with patient functioning.

CONCLUSIONS

Patients with SCI must deal with a number of secondary complications in addition to any disability caused by the injury itself. Of 7 symptoms studied, pain, weakness, and fatigue appeared to be most common and most closely linked to patient social and mental health functioning. Research is needed to identify the causal relationships between perceived symptoms and quality of life in patients with SCI and to identify effective treatments for those symptoms shown to impact patient functioning.
