RESUMEN

STUDY DESIGN: Retrospective and prospective observational. OBJECTIVE: The main objective of this study was to analyse suicide attempt as a cause of traumatic spinal cord injury (tSCI) and suicide as a cause of death after tSCI. SETTING: This study was conducted at two British spinal centres, Stoke Mandeville and Southport. METHODS: Long-term survival of patients who were newly admitted between 1991 and 2010, had survived the first post-injury year and had neurological deficit on discharge. Follow-up was discontinued on 31 December 2014. RESULTS: Among the 2304 newly admitted cases of tSCI, suicide attempt was the cause of injury in 63 cases (2.7%). By the end of 2014 there were 533 deaths of which 4.2% deaths were by suicide, with 91% of suicides happening in the first 10 years post injury. Multiple logistic regression analyses showed a higher mortality odds ratio (OR=4.32, P<0.001) and a much higher suicide OR (9.46, P<0.001) for persons injured in suicide attempts when compared with all other SCI aetiologies. The overall age-standardised suicide mortality rate was 62.5 per 100 000 persons per year (95% confidence interval=36.4-88.6), five times higher than the general population suicide rate for England and Wales in 2014 (12.2 per 100 000). CONCLUSIONS: Suicide attempt was the cause of tSCI in 2.7% of the sample and suicide was the cause of death in 4.2% of all deaths. The overall mortality and death by suicide were significantly higher in persons whose tSCI was caused by an attempted suicide when compared with the rest of the sample. Continued psychological attention following SCI, especially to those who were injured by suicide attempt, is warranted.

RESUMEN

DESIGN: Retrospective and prospective observational. OBJECTIVE: Analyse causes of death after traumatic spinal cord injury (tSCI) in persons surviving the first year post injury, and establish any trend over time. SETTING: Two spinal centres in Great Britain. METHODS: The sample consisted of 5483 patients with tSCI admitted to Stoke Mandeville and Southport spinal centres who were injured between 1943 and 2010, survived first year post injury, had residual neurological deficit on discharge and were British residents. Mortality information, including causes of death, was collected up to 31 December 2014. Age-standardised cause-specific mortality rates were calculated for selected causes of death, and included trends over time and comparison with the general population. RESULTS: In total, 2322 persons (42.3% of the sample) died, with 2170 (93.5%) having a reliable cause of death established. The most frequent causes of death were respiratory (29.3% of all certified causes), circulatory, including cardiovascular and cerebrovascular diseases (26.7%), neoplasms (13.9%), urogenital (11.5%), digestive (5.3%) and external causes, including suicides (4.5%). Compared to the general population, age-standardised cause-specific mortality rates were higher for all causes, especially skin, urogenital and respiratory; rates showed improvement over time for suicides, circulatory and urogenital causes, no significant change for neoplasms, and increase for skin and respiratory causes. CONCLUSIONS: Leading causes of death after tSCI in persons surviving the first year post injury were respiratory, circulatory, neoplasms and urogenital. Cause-specific mortality rates showed improvement over time for most causes, but were still higher than the general population rates, especially for skin, urinary and respiratory causes.

RESUMEN

STUDY DESIGN: Retrospective and prospective observational. OBJECTIVES: Analyse long-term survival after traumatic spinal cord injury (SCI) in Great Britain over the 70-year study period, identify mortality risk factors and estimate current life expectancy. SETTING: Two spinal centres in Great Britain. METHODS: The sample consisted of patients with traumatic SCI injured 1943-2010 who survived the first year post-injury, had residual neurological deficit on discharge and were British residents. Life expectancy and trends over time were estimated by neurological grouping, age and gender, using logistic regression of person-years of follow-up combined with standard life table calculations. RESULTS: For the 5483 cases of traumatic SCI the mean age at injury was 35.1 years, 79.7% were male, 31.1% had tetraplegia AIS/Frankel ABC, 41.2% paraplegia ABC,and 27.7% functionally incomplete lesion (all Ds). On 31 December 2014, 54% were still alive, 42.3% had died and 3.7% were lost to follow-up. Estimated life expectancies improved significantly between the 1950s and 1980s, plateaued during the next two decades, before slightly improving again since 2010. The estimated current life expectancy, compared with the general British population, ranged from 18.1 to 88.4% depending on the ventilator dependency, level and completeness of injury, age and gender. CONCLUSIONS: Life expectancy after SCI improved significantly between the 1950s and 1980s, plateaued during the 1990s and 2000s, before slightly improving again since 2010, but still remains well below that of the general British population.

RESUMEN

STUDY DESIGN: Psychometric study. OBJECTIVES: To determine the intra- and inter-rater reliability and content validity of the International Spinal Cord Injury (SCI) Musculoskeletal Basic Data Set (ISCIMSBDS). SETTING: Four centers with one in each of the countries in Australia, England, India and the United States of America. METHODS: A total of 117 participants with a C2 to S1 neurological level and American Spinal Injury Association Impairment Scale A to D injury were recruited. The median (interquartile range) time since injury was 9 years (2-29). Fifty-seven participants were assessed by the same assessor, and 60 participants were assessed by two different assessors on two different occasions to determine the intra- and inter-rater reliability, respectively. Kappa statistics or crude agreement was used to measure reliability. Content validity was assessed through focus group interviews of people with SCI and health-care professionals. RESULTS: The intra-rater reliability ranged from κ=0.62 to 1.00 and crude agreement from 75% to 100% for each of the variables on the ISCIMSBDS. The inter-rater reliability ranged from κ=-0.25 to 1.00, with a diverse crude agreement ranging from 0% to 100%. The inter-rater reliability was unsatisfactory for the following variables: 'Date of fracture', 'Fragility fractures', 'Scoliosis, method of assessment', 'Other musculoskeletal problems' and 'Do any of the above musculoskeletal challenges interfere with your activities of daily living (transfers, walking, dressing, showers, etc.)?'. Results from validity discussions implied no major suggestions for changes. CONCLUSION: Overall, the ISCIMSBDS is reliable and valid, although 5 of the 12 variables may benefit from further refinement.

RESUMEN

BACKGROUND: Disability scales do not enable the transmission of concise, meaningful and daily function description for clinical purposes. STUDY DESIGN: Cross-sectional statistical analysis of 328 patients' Spinal Cord Independence Measure (SCIM) III item scores (SIS). OBJECTIVE: To develop a concise and clinically interpretable data-based characterization of daily task accomplishment for patients with spinal cord lesions (SCLs). SETTING: Multi-center study at 13 spinal units in 6 countries. METHODS: Patients were grouped into clusters characterized by smaller differences between the patients' SIS within the clusters than between their centers, using the k-medoides algorithm. The number of clusters (k) was chosen according to the percent of SIS variation they explained and the clinical distinction between them. RESULTS: Analysis showed that k=8 SIS clusters offer a good description of the patient population. The eight functional clusters were designated as A-H, each cluster (grade) representing a combination of task accomplishments. Higher grades were usually (but not always) associated with patients implementing more difficult tasks. Throughout rehabilitation, the patients' functional grade improved and the distribution of patients with similar functional grades within the total SCIM III score deciles remained stable. CONCLUSIONS: A new classification based on SIS clusters enables a concise description of overall functioning and task accomplishment distribution in patients with SCL. A software tool is used to identify the patients' functional grade. Findings support the stability and utility of the grades for characterizing the patients' functional status.

RESUMEN

STUDY DESIGN: Prospective longitudinal experimental study. OBJECTIVES: The aim of this study was to assess the sensitivity to change of the electrical perceptual threshold (EPT) test during the longitudinal monitoring of neurological changes in patients with incomplete spinal cord injury (SCI). SETTING: National Spinal Injuries Centre, Stoke Mandeville Hospital, Buckinghamshire Hospitals NHS Trust, Buckinghamshire, UK. METHODS: Perceptual threshold to 3 Hz cutaneous electrical stimulation was measured in 11 patients with incomplete SCI at selected American Spinal Injuries Association (ASIA) sensory key points on four occasions. The first three measurements were performed within a 5-day period (baseline) and the fourth measurement (follow-up) at least 9 months later. The results were tested for statistical significance and the effect sizes were calculated. RESULTS: There were no significant differences between the EPT results of the three baseline assessments. When the mean baseline and follow-up EPT results were compared, there were no significant differences in EPT values above the sensory level of lesion, but a significant difference (reduction in threshold values) was found at and below the level of SCI, with medium and large effect sizes, respectively. CONCLUSION: The EPT test showed good sensitivity to change in dermatomes at and directly below the sensory level of the SCI. This makes it a potentially useful quantitative sensory instrument for detecting changes in sensory function during longitudinal monitoring of patients with SCI.

RESUMEN

STUDY DESIGN: Multicenter international cohort study. OBJECTIVE: The objective of this study was to establish target values for Spinal Cord Independence Measure (SCIM) III scoring in rehabilitation for clinically complete spinal cord lesion (SCL) neurological levels. SETTING: In total, 13 spinal cord units in six countries from North America, Europe and the Middle East were taken. METHODS: Total SCIM III scores and gain at discharge from rehabilitation were calculated for SCL levels in 128 patients with American Spinal Injury Association Impairment Scale (AIS) grade A on admission to rehabilitation. RESULTS: Median, quartiles, mean and s.d., values of discharge SCIM III scores and SCIM III gain for the various SCL levels are presented. Total SCIM III scores and gain were significantly correlated with the SCL level (r=0.730, r=0.579, P<0.001). CONCLUSIONS: Calculated discharge SCIM III scores can be used as target values for functional achievements at various neurological levels in patients after AIS A SCL. They are generally, but not always, inversely correlated with SCL level.

RESUMEN

STUDY DESIGN: A multi-center international cohort study. OBJECTIVE: To evaluate the reliability and validity of the third version of the Spinal Cord Independence Measure (SCIM III), separately for patients with traumatic spinal cord lesions (SCLs). SETTING: A total of 13 spinal cord units in six countries from North America, Europe and the Middle-East. METHODS: SCIM III and Functional Independence Measure (FIM) were assessed for 261 patients with traumatic SCLs, on admission to rehabilitation and before discharge, by two raters. Conventional statistical measures were used to evaluate the SCIM III reliability and validity. RESULTS: In almost all SCIM III tasks, the total agreement between the paired raters was >80%. The κ coefficients were all >0.6 and statistically significant. Pearson's coefficients of the correlations between the paired raters were >0.9, the mean differences between raters were nonsignificant and the intraclass correlation coefficients (ICCs) were ≥ 0.95. Cronbach's α values for the entire SCIM III scale were 0.833-0.835. FIM and SCIM III total scores were correlated (r=0.84, P<0.001). SCIM III was more responsive to changes than FIM. In all subscales, SCIM III identified more changes in function than FIM, and in 3 of the 4 subscales, differences in responsiveness were statistically significant (P<0.02). CONCLUSION: The results confirm the reliability and validity of SCIM III for patients with traumatic SCLs in a number of countries.

RESUMEN

PURPOSE: To examine the third version of the Spinal Cord Independence Measure (SCIM III) for reliability and validity in a multi-center cohort study. METHOD: Four hundred and twenty-five patients with spinal cord lesions from 13 spinal cord units in six countries from three continents were assessed with SCIM III and the Functional Independence measure (FIM) on admission to rehabilitation and before discharge. RESULTS: Total agreement between raters was above 80% in most SCIM III tasks, and all kappa coefficients were statistically significant (P<0.001). The coefficients of Pearson correlation between the paired raters were above 0.9, and intraclass correlation coefficients were above 0.94. Cronbach's alpha was above 0.7. The coefficient of Pearson correlation between FIM and SCIM III was 0.790 (P<0.01). SCIM III was more responsive to changes than FIM in the subscales of Respiration and sphincter management and Mobility indoors and outdoors. CONCLUSIONS: The results support the reliability and validity of SCIM III in a multi-cultural setup. Despite several limitations of the study, the results indicate that SCIM III is an efficient measure for functional assessment of SCL patients and can be safely used for clinical and research trials, including international multi-center studies.

RESUMEN

Over the last decade, several methods have been designed to improve the survival rate of vitrificated embryos. Although some teams have succeeded, the main remaining drawback of these methods is that they do not provide a leak proof environment for cryopreserved biological samples. To respond to that demand in respect with the European reglementation, the Cryo Bio System company (CBS) designed the HSV High Security Vitrification Kit (HSV). This system is composed of three distinct parts, a High Security thermal-autogenic sealed clear straw, a capillary with its extremity in form of a gutter, and an introducer that can be mounted on the manipulation rod before introduction into the straw. In this study, we confirmed that the CBS vitrification kit is a suitable method for vitrification in association with a small amount of cryoprotector enriched viscous media such as 25 microM Ficool 400, 750 mM Sucrose, 1% Bovine albumin, 20% Dimethyl Sulfoxide and 20% Ethylene glycol in a Phosphate buffered saline solution. We also evaluated the speed of the temperature decrease during vitrification in comparison with four other commercially available non-aseptic methods and showed the protective role of the CBS system during transfer. These physical data have now been confirmed biologically by P. Vanderzwalmen who obtained easily reproductible good results with human embryo using our method. Today, the HSV represents the unique aseptic alternative device (EC and FDA approved) for embryos, oocytes, and biological samples vitrification.

RESUMEN

INTRODUCTION: The issue of evaluating the efficiency of health systems has been elaborated upon frequently. Since "health" is a multi-faceted concept, many variables of different measurement units must be included in its analysis; consequently, this presents a great obstacle for researchers to overcome. MATERIALS AND METHODS: A novel statistical approach for evaluating the efficiency of organizational units is here proposed, which can also be easily applied to the health sector. For these purposes, the health status of the 27 countries belonging to the European Union has been examined by employing a statistical Ivanovic-Jeremic Distance Based Analysis (DBA) on various health indicators. RESULTS: The subsequent outcome of the Distance Based Analysis has shown that Cyprus and Ireland have a most efficient health system sectors. Greece also has exceptional indicators of health service, yet health on the individual level is not comparable. LIMITATIONS: Since it synthesizes many variables into an efficiency score, a DBA can be easily applied to other regions/countries. However, the choice of input and output variables can be considered to be potential limitations since a different choice of variables may cause different efficiency scores for the countries selected. CONCLUSIONS: A DBA approach contributes significantly to the efficiency in the field of research measurement. This analysis can be additionally performed alongside DEA and SFA methods, as a new measure of efficiency.

RESUMEN

STUDY DESIGN: Cross-sectional; survey. OBJECTIVES: To describe the utilization, accessibility and satisfaction of primary and preventive health-care services to individuals with long-term spinal cord injuries, and compare results among three countries: the United States, Canada and the United Kingdom. SETTING: The Canadian sample was obtained from the Canadian Paraplegic Association-Ontario and Manitoba Divisions. The British sample was recruited from the Northwest Regional Spinal Injuries Centre in Southport and National Spinal Injuries Centre at Stoke Mandeville Hospital in Aylesbury. The American sample was recruited through Craig Hospital in Englewood, CO, USA. METHOD: A total sample of 373 individuals aging with a spinal cord injury participated in a mailed survey. The Health Care Questionnaire was used to measure utilization, access and satisfaction with primary care and preventive services. RESULTS: In total, 93% of individuals reported having a family doctor, 63% had a spinal injuries specialist and 56% had both a family doctor and spinal injuries specialist. Considerable duplication of services occurred for general medical and preventive services, although lifestyle and emotional issues were not addressed for over 75% of the participants. Significant differences were found in utilization among Canada, US and UK, with Canadians most likely to receive health care from family physicians and Americans most likely to receive care from specialists. Access to and satisfaction with health services was not significantly different among countries. CONCLUSION: People with long-standing spinal cord injuries develop complex maps by which they seek out appropriate primary health-care and preventive services. Given the differences among countries, it is clear that the health delivery model plays an important role in how and where individuals receive health services.

RESUMEN

STUDY DESIGN: Prospective observational. AIM: To examine inter-rater reliability of motor and sensory examinations performed according to American Spinal Injury Association (ASIA) standards. SETTING: National Spinal Injuries Centre, Stoke Mandeville Hospital, Buckinghamshire Hospitals NHS Trust, UK. MATERIAL AND METHOD: Results of ASIA motor and sensory examinations performed by two experienced examiners on 45 patients with spinal cord injury (SCI) were compared. RESULTS: Total ASIA scores showed very strong correlation between the two examiners, with Pearson correlation coefficients and intraclass correlation coefficients exceeding 0.96, P<0.01 for total motor, light touch and pin prick scores. The agreement for individual muscle testing of the 10 ASIA key muscles showed substantial agreement for majority of muscles, with the weighted Kappa coefficient range 0.649-0.993, P<0.05. The overall agreement in assignment of manual muscle testing grades (0-5) was 82% on the right and 84% on the left, with the strongest agreement for grade '0' and the weakest for grade '3'. The unweighted Kappa coefficient for agreement in motor and sensory levels ranged from 0.68 to 0.78 (P<0.01). There was no difference in ASIA impairment grades derived from the two examiners' results. CONCLUSIONS: Our study results showed very good levels of agreement in ASIA clinical examinations between two experienced examiners. The established degree of variability due to inter-rater differences should be taken into account in study design of clinical trials with more than one assessor..

RESUMEN

BACKGROUND: A third version of the Spinal Cord Independence Measure (SCIM III), made up of three subscales, was formulated following comments by experts from several countries and Rasch analysis performed on the previous version. OBJECTIVE: To examine the validity, reliability, and usefulness of SCIM III using Rasch analysis. DESIGN: Multicenter cohort study. SETTING: Thirteen spinal cord units in six countries from North America, Europe, and the Middle-East. SUBJECTS: 425 patients with spinal cord lesions (SCL). INTERVENTIONS: SCIM III assessments by professional staff members. Rasch analysis of admission scores. MAIN OUTCOME MEASURES: SCIM III subscale match between the distribution of item difficulty grades and the patient ability measurements; reliability of patient ability measures; fit of data to Rasch model requirements; unidimensionality of each subscale; hierarchical ordering of categories within items; differential item functioning across classes of patients and across countries. RESULTS: Results supported the compatibility of the SCIM subscales with the stringent Rasch requirements. Average infit mean-square indices were 0.79-1.06; statistically distinct strata of abilities were 3 to 4; most thresholds between adjacent categories were properly ordered; item hierarchy was stable across most of the clinical subgroups and across countries. In a few items, however, misfit or category threshold disordering were found. CONCLUSIONS: The scores of each SCIM III subscale appear as a reliable and useful quantitative representation of a specific construct of independence after SCL. This justifies the use of SCIM in clinical research, including cross-cultural trials. The results also suggest that there is merit in further refining the scale.

RESUMEN

STUDY DESIGN: Prospective experimental. OBJECTIVES: The aim of this study was to develop a quantitative sensory test (QST) that could be used for assessing the level and the density (degree of impairment) of spinal cord injury (SCI) and for monitoring neurological changes in patients with SCI. SETTING: National Spinal Injuries Centre, Stoke Mandeville Hospital, Buckinghamshire Hospitals NHS Trust, UK. METHODS: Perceptual threshold to 3 Hz cutaneous electrical stimulation was measured in 30 control subjects and in 45 patients with SCI at American Spinal Injuries Association (ASIA) sensory key points for selected dermatomes between C3 and S2 bilaterally. Electrical perceptual threshold (EPT) was recorded as the lowest ascending stimulus intensity out of three tests at which the subject reported sensation. The level of SCI according to EPT results was established for right and left sides as the most caudal spinal segment at which patient's EPT was within the control range (mean +/- 2 standard deviation (SD)). The level of SCI, according to EPT, was then compared with clinical sensory level derived according to ASIA classification. RESULTS: In the control group, EPT depended on the dermatome tested and was lowest for T1 (1.01 +/- 0.23 mA, mean +/- SD) and highest for L5 (3.32 +/- 1.14 mA). There was strong correlation between corresponding right and left dermatomes and between repeated assessments. In the SCI group, the level of lesion according to EPT and clinical testing was the same in 43 of the 90 tests (48%). In 37 cases (41%), the EPT level was higher than the clinical level, and in 10 cases (11%), it was lower. Below the level of lesion in incomplete SCI and in the zone of partial preservation in complete SCI, the EPT values in most dermatomes were raised compared with the control group. CONCLUSIONS: EPT is a simple, reproducible QST that can assess both the level and the density of SCI. It seems to add sensitivity and resolution to the standard clinical testing and could be a useful adjunct in longitudinal monitoring of patients with SCI for research purposes during natural recovery and therapeutic interventions.

RESUMEN

STUDY DESIGN: Postal questionnaire survey. OBJECTIVE: To examine the current use of hormone replacement therapy (HRT) in a sample of menopausal women with spinal cord injury (SCI). SETTING: National Spinal Injuries Centre (NSIC), Stoke Mandeville Hospital, Aylesbury, UK. METHOD: A postal questionnaire was sent to 94 women from the NSIC patient database who met the study inclusion criteria (wheelchair dependent, aged 49 years and above, last seen or heard from within the last 3 years). RESULTS: A total of 59 valid questionnaires were analysed. At the time of the survey, 50 women were menopausal and 11 of them were using HRT, six for menopausal symptoms and five for osteoporosis prevention. Another 11 had used HRT, eight for menopausal symptoms and three for osteoporosis prevention, but had discontinued it. The main reasons for stopping HRT were side effects. Of the 28 women who had never been on HRT, 20 had either enquired about it, or had been offered HRT, but decided against it. Of the nine women who were still premenopausal at the time of the survey, four would consider using HRT. CONCLUSIONS: Results show that 44% of the menopausal women in our sample have used HRT at some point and 22% still do, mostly for treatment of menopausal symptoms and for osteoporosis prevention. In view of the latest literature findings in able-bodied women, use of HRT for osteoporosis prevention in women with SCI may have to be reconsidered.

RESUMEN

AIMS: Risk of treatment-related problems in spinal cord injury (SCI) mandates assessment of complication rates of different bladder management methods (BMMs). The current study evaluated aging-related complications of various BMMs over a 6-year period in a population with spinal cord injury for at least 20 years. MATERIALS AND METHODS: Clinical parameters were compared using a linear mixed effects model, controlling for various confounding variables, to establish complication trends with aging and their association with BMM. Results for people whose BMM was changed during the study were evaluated separately as well as in combination with the whole population. RESULTS: One hundred and ninety six people (mean age 57.4 and years post injury (YPI) 33) were evaluated on three occasions. Both age and YPI were significantly associated with rising complication rates regardless of BMM. The BMMs assessed differed in terms of complication rates. In comparison with balanced reflex voiding, straining was significantly better for renal structural abnormality. Intermittent catheterization was associated with significantly worse renal function, possibly for demographic reasons. Overall, 28.8% changed BMM during the study period, particularly, those using straining or balanced reflex voiding. The probability of change increased with age and YPI. Reasons for change of BMM were varied and there was no specific association between reason for change and BMM. CONCLUSIONS: Aging and duration of injury substantially influence urological complication rates, and BMM options differ in respect of prevalence and incidence of complications. At a late stage post injury there remains a high probability of change in BMM. The findings indicate the importance of long-term planning from the time of injury to minimize late complications.

RESUMEN

The sialic acid residues of human alpha 1-protease inhibitor were modified by periodate oxidation and subsequent reductive amination with ethanolamine and sodium cyanoborohydride. The modified inhibitor retained its original trypsin inhibitory activity and was not digested by neuraminidase from Clostridium perfringens. The modified inhibitor disappeared from rat blood circulation at the same rate as the native inhibitor.

RESUMEN

The aim of this study was to compare the attendance rates for cervical and breast cancer screening in wheelchair dependent spinal cord injured (SCI) women with those in the general female population in England. The study was conducted as a postal questionnaire survey with an effective response rate of 79%. The attendance rates of the eligible SCI groups were 84% for cervical screening and 72% for mammography, both figures being well within the national average attendance rates in the general female population. Difficulties with cervical screening were reported in 58% and with mammography in 43% of the cases, including restricted access to clinics, examining rooms and examining couches and positioning during the procedure. These were also the main reasons given for non attendance. The article points out ways to enable even more wheelchair dependent women to benefit from the preventative screening programmes.

RESUMEN

STUDY DESIGN: A pilot postal survey. OBJECTIVE: To examine the levels of sporting/recreational activities, education and employment in people with spinal cord injury (SCI) and to assess if involvement in sport and recreation is associated with higher levels of education and employment. SETTING: National Spinal Injuries Centre (NSIC), Stoke Mandeville Hospital, Aylesbury, UK. METHODS: Forty-five subjects, who met the following criteria: SCI at level C5 or below, wheelchair dependent, aged between 18 and 50 at the time of injury, injured at least 10 years ago, admitted to the NSIC within 6 months of injury and resident in the UK, completed a 26-item postal questionnaire. RESULTS: Among the 45 subjects 47% participated in physical activities (20% in sport; 27% in recreation), 33% were employed (29% full-time) and 18.5% had undergone further education at the time of the survey. Participation in sports as well as employment status decreased after injury (P<0.01) usually as a result of poor access to sports and work facilities. Only 4% of investigated SCI patients started to practise physical activity after the accident whilst 42% stopped. CONCLUSIONS: Levels of sporting/recreational activities and employment decreased significantly after injury. No significant correlation was found between sport/recreation involvement and education/employment status. Further investigation with a large number of participants that will enable additional analysis of subgroups, such as level of injury and functional independence, is required.
