Background: Following traumatic brain and spinal cord injuries, maximising community participation leads to better physical and mental health outcomes.

Objectives: To determine the effectiveness and health system resource use of a group intervention (CarFreeMe TI) on community participation in people with complex trauma injuries.

Method: Randomised crossover trial of 54 participants, recruited from rehabilitation services in Adelaide, Australia. Inclusion criteria is a trauma injury, unable to return to full driving, aged over 18 years of age, adequate cognition/behavioural/communication abilities to participate in sessions and mobile. Exclusion criterion is living in setting where alternative transport is provided. Participants will be randomly assigned on a 1:1 allocation basis, to receiving Phase 1 CarFreeMe TI-group-based intervention or Phase 2 information related to transport options. Then, crossover to Phase 1 or 2 will occur. Primary outcome measure is community participation using a Global Positioning System. Secondary outcome measures include Community Mobility Self-efficacy Scale; CarFreeMe TI Transport Questionnaire, AQOL, EQ-5D-5L; Carer's Community Mobility Self-efficacy Scale and Modified Carer Strain Index for carers of participants. Outcome assessors will be blinded to group allocation. All analyses will be on an intention to treat basis with difference in community participation between the groups determined via a GLM ANOVA and the significance between groups on other measures using independent sample t-tests. It is hypothesised that the community mobility intervention (CarFreeMeTI) will result in increased community participation.

Discussion: The results will provide proof of concept information on the feasibility and inform allocation of resources for people with complex trauma injuries.

Objectives: Exoskeletons are electromechanical devices that are worn by a human operator to increase their physical performance. Several exoskeletons have been developed to restore functional movements, such as walking, for those with paralysis due to neurological impairment. However, existing exoskeletons have limitations with respect to affordability, size, weight, speed, and efficiency, which may reduce their functional application. Therefore, the aim of this scoping review is to collect and narratively synthesize the perspectives of users of exoskeleton technology.

Methods: A systematic literature search was conducted across several healthcare related online databases.

Results: A total of 4,619 articles were identified, of which 51 were selected for full review. Only three studies were identified that met the inclusion criteria. Of these, one showed an incongruence between users’ expectations and experiences of device use; another reported perspectives on potential rather than actual device use, ranking design features in order of perceived importance; and the other reported ratings of ease of device use in training.

Conclusions: The heterogeneity of studies included within this review, leave the authors unable to suggest consensus as to user perspectives of exoskeleton technology. However, it is apparent that users are able to suggest priorities for exoskeleton design and that users’ perspectives of exoskeleton technology might change in response to experience of use. The authors, therefore, suggest that exoskeleton design should be an iterative process, whereby user perspectives are sought, incorporated and refined by tangible experience, to ensure that devices developed are acceptable to and usable by the populations they seek to re-enable.

Certain probiotics may prevent the development of antibiotic-associated diarrhoea (AAD) and Clostridium difficile-associated diarrhoea (CDAD), but their effectiveness depends on both strain and dose. There are few data on nutritional interventions to control AAD/CDAD in the spinal cord injury (SCI) population. The present study aimed to assess (1) the efficacy of consuming a commercially produced probiotic containing at least 6·5 × 109 live Lactobacilluscasei Shirota (LcS) in reducing the incidence of AAD/CDAD, and (2) whether undernutrition and proton pump inhibitors (PPI) are risk factors for AAD/CDAD. A total of 164 SCI patients (50·1 (sd 17·8) years) with a requirement for antibiotics (median 21 d, range 5–366) were randomly allocated to receive LcS (n 76) or no probiotic (n 82). LcS was given once daily for the duration of the antibiotic course and continued for 7 days thereafter. Nutritional risk was assessed by the Spinal Nutrition Screening Tool. The LcS group had a significantly lower incidence of AAD (17·1 v. 54·9 %, P< 0·001). At baseline, 65 % of patients were at undernutrition risk. Undernutrition (64·1 v. 33·3 %, P< 0·01) and the use of PPI (38·4 v. 12·1 %, P= 0·022) were found to be associated with AAD. However, no significant difference was observed in nutrient intake between the groups. The multivariate logistic regression analysis identified poor appetite ( < 1/2 meals eaten) (OR 5·04, 95 % CI 1·28, 19·84) and no probiotic (OR 8·46, 95 % CI 3·22, 22·20) as the independent risk factors for AAD. The present study indicated that LcS could reduce the incidence of AAD in hospitalised SCI patients. A randomised, placebo-controlled study is needed to confirm this apparent therapeutic success in order to translate into improved clinical outcomes.

Data on the prevalence of malnutrition among patients with spinal cord injuries (SCI) are lacking. The aim of the present study was to assess nutritional risk at admission, and the status of nutritional support in the UK SCI Centres (SCIC); a cross-sectional, multicentre study in four SCIC. A standardised questionnaire was used and distributed to the participating SCIC. After obtaining informed consent, baseline demographic data, nutritional risk score by the ‘Malnutrition Universal Screening Tool’, BMI and routine blood biochemistry were collected from every patient admitted to an SCIC. The four SCIC, comprising 48·2 % of the total UK SCI beds, contributed data from 150 patients. On admission, 44·3 % of patients were malnourished or at risk of undernutrition. Nutritional risk was more common in patients with acute high cervical SCI than those with lower SCI (60·7 v. 34·5 %), and nutritional risk was more common in those with additional complications including ventilatory support (with tracheostomy, 56·3 v. 38·7 %). Also, 45 % of patients were at risk of overnutrition (BMI ≥ 25 kg/m2). The prevalence of malnutrition in SCI patients admitted to SCIC is higher than national figures focused on general hospitalised patients, indicating that SCI patients are particularly vulnerable to malnutrition. Patients with SCI who have a tracheostomy may need additional attention. Given the potential negative impact of malnutrition on clinical outcomes, an emphasis on mandatory nutrition screening, followed by detailed assessment for at-risk individuals should be in place in the SCIC.

Summary

Background and objective: We recently demonstrated that intrathecal bupivacaine before or after acute photochemical spinal injury improved functional outcome in rats. However, the closest model to spinal trauma is the contusive weight-drop method. The aim of this study was to evaluate functional, electrophysiological and anatomical consequences of a contusive spinal-cord lesion in rats with or without an intrathecal injection of bupivacaine. Methods: Fifteen minutes before a contusive spinal lesion, 18 rats received intrathecally either 0.5% bupivacaine (Group T) or saline (Group C). During an 18-days period, motor and sensory functions were evaluated, and bladder voiding dysfunction was noted. Somatosensory evoked potential testings were performed at day 18. Then, the intact spinal cord area at the epicentre of the lesion and the extent of the lesion were measured. Results: Motor deficit was less and inclined-plane stability was better in treated animals at all times, the scores were statistically different from day 7. There were no differences concerning the sensory test. Despite no significant difference, there were less spinal bladders in the T group from day 7. Somatosensory evoked potential latencies were longer in T group, but only the first negative component (N1) was statistically significant. Amplitudes were higher in T group, but were not statistically different. The spinal cord intact area at the epicentre of the lesion was higher in the T group (1.23 ± 0.8 mm2 vs. 0.81 ± 0.39 mm2; P < 0.05). The extent of the lesion was higher in the C group (9.4 ± 2.9 mm vs. 6.4 ± 3.4 mm; P < 0.05). Conclusion: Intrathecal 0.5% bupivacaine provide a neuroprotective effect by decreasing functional, electrophysiological and anatomical consequences after a contusive spinal cord injury.

This study aimed to investigate factors associated with persistent Post-Traumatic Stress Disorder (PTSD) in people with Spinal Cord Injury (SCI). In the context of a cognitive model, it sought to determine how influential cognitive appraisals were in predicting persistent PTSD when compared to other known predictor variables in the literature such as injury severity. A sample of 50 inpatients receiving rehabilitation for SCI who were 3–24 months post-injury were interviewed using a series of standardized measures of PTSD symptoms and diagnosis, post-traumatic cognitive appraisals, social support, and injury severity. For PTSD symptoms, significant relationships were found for greater injury severity, lower satisfaction with social support and more negative cognitions. Negative cognitions were found to predict variance in PTSD symptoms over and above the non-cognitive variables, although gender and injury severity were also predictors. The only significant predictor of PTSD diagnosis was the cognitive sub-scale “negative cognitions about the self”. Cognitive appraisals were found to be important predictors of persisting PTSD in an SCI population. This supports the cognitive model of PTSD and the development of cognitive therapies for PTSD in this population.
