The overlooked outcome measure for spinal cord injury: use of assistive devices

Although several outcome measures are used to assess various areas of interest regarding spinal cord injuries (SCIs), little is known about the frequency of their use, and the ways in which they transform shared knowledge into implemented practices. Herein, 800 professionals from the International Spinal Cord Society, especially trained for caring in patients with SCI, were invited to respond to an Internet survey collecting information on the use of standardized measures in daily clinical practices. We asked both clinicians and researchers with different areas of interest about their use of functional outcome measures, and, in particular, which scales they habitually use to assess various aspects of clinical practice and rehabilitation. We selected a set of rating scales, which were validated for measuring SCIs (http://www.scireproject.com/outcome-measures). The results show that the areas of interest assessed by most of the participants were neurological status, upper limb, lower limb gait, pain, spasticity, self-care, and daily living. The most widely used rating scales were the spinal cord independence measure, the functional independence measure and the International Standards for Neurological Classification of Spinal Cord Injury. Instead, the majority of respondents did not evaluate the use of assistive technology. Despite the availability of several outcome scales, the practice of evaluating SCIs with standardized measures for assistive technologies and wheelchair mobility is still not widespread, even though it is a high priority in the rehabilitation of SCI patients. The results emphasize the need for a more thorough knowledge and use of outcome scales, thus improving the quality of assistive device evaluation

Prediction of functional outcome after spinal cord injury: a task for the rehabilitation team and the patient

Study design: Descriptive analysis of data gathered in an information system.Objectives: To explore the predictions of professionals and patients regarding functional outcome after spinal cord injury related to the final results after inpatient rehabilitation, in order to make prognostics of rehabilitation outcome more successful and enlarge the role of the patient in selecting realistic rehabilitation goals.Methods: Data from 55 patients with spinal cord injury admitted to the rehabilitation centre. Expectations of the rehabilitation team and the patients regarding future independence in performing six daily activities were compared to the functional results at discharge. The results of patients with different level and extent of lesion were analyzed.Results: In 52% of all performed skills, independence was achieved at discharge. Professionals and patients made similar predictions. If they both expected independence after rehabilitation, 90% of the skills were performed independently at discharge. If they both did not expect independence only 3% of the functional results were positive. Of all combined predictions 64% was correct. Correct predictions were most often found regarding self-care skills of patients with paraplegia and regarding mobility of patients with complete lesions. Prediction of self-care outcome of patients with tetraplegia is far more complicated. There was a considerable variation in predictions of mobility potential, especially regarding patients with incomplete lesions. If the team and patients agreed upon expected independence in mobility skills of these patients, the final results were mostly positive.Conclusions: Prediction of functional outcome after spinal cord injury was most successful if the expectations of the team and patients were combined. Prognosis of self-care outcome of patients with paraplegia and mobility potential of patients with complete spinal cord lesions was usually clear at admission. However, selection of realistic goals concerning self-care skills of patients with tetraplegia and mobility skills of patients with incomplete lesions is far more complicated. Gradual adjustment of objectives is needed during the rehabilitation process in close collaboration between the professionals and the patients

Auto-titrating continuous positive airway pressure treatment for obstructive sleep apnoea after acute quadriplegia (COSAQ): study protocol for a randomized controlled trial

BACKGROUND: Quadriplegia is a severe, catastrophic injury that predominantly affects people early in life, resulting in lifelong physical disability. Obstructive sleep apnoea is a direct consequence of quadriplegia and is associated with neurocognitive deficits, sleepiness and reduced quality of life. The usual treatment for sleep apnoea is nasal continuous positive airway pressure (CPAP); however, this is poorly tolerated in quadriplegia. To encourage patients to use this therapy, we have to demonstrate that the benefits outweigh the inconvenience. We therefore propose a prospective, multinational randomized controlled trial of three months of CPAP for obstructive sleep apnoea after acute quadriplegia. METHODS/DESIGN: Specialist spinal cord injury centres across Australia, New Zealand, the UK and Canada will recruit medically stable individuals who have sustained a (new) traumatic quadriplegia (complete or incomplete second cervical to first thoracic level lesions). Participants will be screened for obstructive sleep apnoea using full, portable sleep studies. Those with an apnoea hypopnoea index greater than 10 per hour will proceed to an initial three-night trial of CPAP. Those who can tolerate CPAP for at least 4 hours on at least one night of the initial trial will be randomized to either usual care or a 3-month period of auto-titrating CPAP. The primary hypothesis is that nocturnal CPAP will improve neuropsychological functioning more than usual care alone. The secondary hypothesis is that the magnitude of improvement of neuropsychological function will be predicted by the severity of baseline sleepiness measures, sleep fragmentation and sleep apnoea. Neuropsychological tests and full polysomnography will be performed at baseline and 3 months with interim measures of sleepiness and symptoms of autonomic dysfunction measured weekly. Spirometry will be performed monthly. Neuropsychological tests will be administered by blinded assessors. Recruitment commenced in July 2009. DISCUSSION: The results of this trial will demonstrate the effect of nocturnal CPAP treatment of obstructive sleep apnoea in acute quadriplegia. If CPAP can improve neurocognitive function after injury, it is likely that rehabilitation and subsequent community participation will be substantially improved for this group of predominantly young and severely physically disabled people.

The effect of elastic abdominal binder use on respiratory function on persons with high spinal cord injury at orthostatic position

Introduction : Spinal cord injury causes respiratory muscles paralysis, especially in high thoracic paraplegia and tetraplegia with injury above or right on the sixth thoracic segment, and also biomechanics, volumes, capacities and respiratory pressures changes in affected people. The elastic abdominal binder provides a mechanical support for respiratory function treatment, assisting with abdominal restraint and abdominal compliance reduction while at orthostatic position. Objective : To verify the elastic abdominal binder effect on the respiratory function of people with spinal cord injuries during standing position with the help of orthostatic table, from vertical angle position of 60° and 90°. Method : The study included 56 people suffering from spinal cord injury with motor level above or right on the sixth thoracic segment. They were randomly divided into four distinct groups regarding the use or not of the binder and different inclinations of the orthostatic table during the evaluation procedure. The measured outcomes were vital capacity, tidal volume, inspiratory and expiratory pressure and oxygen saturation. The descriptive analysis presented according to average and standard deviation or median and interquartile. For the outcomes analysis of the five evaluations, the Analysis of Variance (ANOVA) of two factors with repeated measures was used. Statistical significance was set at 5%. Results : The values obtained from respiratory parameters showed no statistical significance regarding the elastic abdominal binder intervention nor on the angle of the standing position. Conclusion : There was no contrasting effect regarding the use of the binder among the evaluated people, therefore it should not be nominated as a standard procedure in the treatment of spinal cord injury at orthostatic position. However, this procedure should not be absolute contraindicated, thus its effect has not demonstrated any harm to participants. Introdução : A lesão da medula espinhal ocasiona paralisia dos músculos respiratórios, principalmente na tetraplegia e paraplegia torácica alta, com lesão acima ou igual ao sextosegmento torácico, e assim mudanças na biomecânica, volumes, capacidades e pressões respiratórias das pessoas acometidas. A cinta abdominal elástica proporciona um suporte mecânico ao tratamento e cuidados com as alterações da função respiratória destas pessoas, podendo auxiliar na contenção abdominal, reduzindo a complacência abdominal durante a posição ortostática. Objetivo : Verificar os efeitos que a cinta abdominal elástica proporciona à função respiratória das pessoas com lesão medular posicionadas em ortostatismo com auxílio da mesa ortostática, a partir da posição a 60° e 90° de angulação vertical. Método : Participaram deste estudo 56 pessoas acometidas por lesão medular com nível motor igual ou acima do sexto segmento torácico, divididos aleatoriamente em quatro grupos distintos em relação ao uso ou não da cinta e angulações da mesa ortostática durante o procedimento de avaliação. Os desfechos mensurados foram capacidade vital, volume corrente, pressão inspiratória e expiratória máxima e saturação de oxigênio. A análise descritiva apresentou-se por meio de média e desvio padrão ou mediana e interquartis. Para análise dos desfechos nos cinco momentos avaliados utilizou-se a Análise de Variância (ANOVA) de dois fatores com medidas repetidas. A significância estatística foi estipulada em 5%. Resultados : Os valores encontrados para os parâmetros respiratórios avaliados demonstraram que não houve significância estatística em relação à intervenção cinta abdominal elástica e à angulação do ortostatismo. Conclusão : Não houve efeito diferencial em relação ao uso da cinta nas pessoas avaliadas, não podendo ser indicada como um procedimento padrão para as abordagens de tratamento na posição ortostática na lesão medular espinhal. Em contrapartida, este procedimento não deve ser uma contraindicação absoluta, pois, seu efeito não demonstrou malefícios aos participantes

Survey of the needs of patients with spinal cord injury: impact and priority for improvement in hand function in tetraplegics\ud

Objective: To investigate the impact of upper extremity deficit in subjects with tetraplegia.\ud \ud Setting: The United Kingdom and The Netherlands.\ud \ud Study design: Survey among the members of the Dutch and UK Spinal Cord Injury (SCI) Associations.\ud \ud Main outcome parameter: Indication of expected improvement in quality of life (QOL) on a 5-point scale in relation to improvement in hand function and seven other SCI-related impairments.\ud \ud Results: In all, 565 subjects with tetraplegia returned the questionnaire (overall response of 42%). Results in the Dutch and the UK group were comparable. A total of 77% of the tetraplegics expected an important or very important improvement in QOL if their hand function improved. This is comparable to their expectations with regard to improvement in bladder and bowel function. All other items were scored lower.\ud \ud Conclusion: This is the first study in which the impact of upper extremity impairment has been assessed in a large sample of tetraplegic subjects and compared to other SCI-related impairments that have a major impact on the life of subjects with SCI. The present study indicates a high impact as well as a high priority for improvement in hand function in tetraplegics.\ud \u

Biomechanics of Pediatric Manual Wheelchair Mobility

Currently, there is limited research of the biomechanics of pediatric manual wheelchair mobility. Specifically, the biomechanics of functional tasks and their relationship to joint pain and health is not well understood. To contribute to this knowledge gap, a quantitative rehabilitation approach was applied for characterizing upper extremity biomechanics of manual wheelchair mobility in children and adolescents during propulsion, starting, and stopping tasks. A Vicon motion analysis system captured movement, while a SmartWheel simultaneously collected three-dimensional forces and moments occurring at the handrim. A custom pediatric inverse dynamics model was used to evaluate three-dimensional upper extremity joint motions, forces, and moments of 14 children with spinal cord injury (SCI) during the functional tasks. Additionally, pain and health-related quality of life outcomes were assessed. This research found that joint demands are significantly different amongst functional tasks, with greatest demands placed on the shoulder during the starting task. Propulsion was significantly different from starting and stopping at all joints. We identified multiple stroke patterns used by the children, some of which are not standard in adults. One subject reported average daily pain, which was minimal. Lower than normal physical health and higher than normal mental health was found in this population. It can be concluded that functional tasks should be considered in addition to propulsion for rehabilitation and SCI treatment planning. This research provides wheelchair users and clinicians with a comprehensive, biomechanical, mobility assessment approach for wheelchair prescription, training, and long-term care of children with SCI

Optimising return to work practices following catastrophic injury

This paper aims to enhance understanding of the features of optimal return to work practices following traumatic brain and spinal cord injury and identify barriers and facilitators to their implementation. Executive summary People with catastrophic injuries face many long-term challenges in the community as a result of their injury: one of the most problematic can be in returning to work (RTW). It may not only be a significant issue for the person with a catastrophic injury but also for their family, friends, the employment industry, and society. Worldwide mean RTW rates for people with catastrophic injury are approximately 30-40%; however, in Australia the overall mean rate is unknown. Internationally, the best RTW rates reported for moderate to severe traumatic brain injury (TBI) come from the UK, Sweden and USA, whilst for spinal cord injury (SCI) they are in Switzerland and Sweden. There are several differences in the way rates reported are calculated such as the time post-injury, making it difficult to definitively identify whether one country achieves better RTW rates than another. Several studies have been conducted to determine the factors which facilitate and limit RTW for people with catastrophic injury. These include having pre-injury employment, age, education, severity of injury, level of cognitive impairment, being functionally independent, fatigue, psychological adjustment to the change, social support and the work environment to name a few. There is a general lack of understanding of the experience of people with catastrophic injury who return to work and, therefore, little known about how job retention can be successful in the long-term. Four types of VR interventions have been identified to facilitate RTW – 1) program based rehabilitation, 2) supported employment, 3) case co-ordination and 4) hybrid or mixed. An evidence review identified 15 relevant articles and it was found that there was limited high quality evidence to support any type of intervention more effective than the other. There was however moderate evidence identified for the effectiveness of case co-ordination for achieving successful RTW for people with moderate to severe TBI and high level evidence for a specialist TBI-VR combination intervention. A reduction in the claiming of benefits after 1 year was also observed. The most promising RTW intervention for people with SCI appears to be supported employment; however, as only one RCT has provided this evidence, further studies are required. Several factors that affect the likely success of RTW interventions were also identified in exploring the research evidence and implications for future research were identified. Substantial research has been conducted on RTW interventions in people with TBI since the late 1980s, however this is not the same for SCI. High quality evidence and transparent reporting of study details are still lacking. This NTRI Forum aims to enhance understanding of the features of optimal return to work practices following traumatic brain and spinal cord injury and identify barriers and facilitators to their implementation. Two questions were identified for deliberation in a Stakeholder Dialogue: 1. In the Australian context, what are the barriers to, and facilitators of, application of strategies to optimise RTW outcomes for people with catastrophic injury? 2. How could identified barriers and facilitators be addressed to ensure successful RTW and better retention of people with catastrophic injury? An accompanying document (Dialogue Summary) will present the results of the deliberation upon these question

Plasticity and awareness of bodily distortion

Knowledge of the body is filtered by perceptual information, recalibrated through predominantly innate stored information, and neurally mediated by direct sensory motor information. Despite multiple sources, the immediate prediction, construction, and evaluation of one’s body are distorted. The origins of such distortions are unclear. In this review, we consider three possible sources of awareness that inform body distortion. First, the precision in the body metric may be based on the sight and positioning sense of a particular body segment. This view provides information on the dual nature of body representation, the reliability of a conscious body image, and implicit alterations in the metrics and positional correspondence of body parts. Second, body awareness may reflect an innate organizational experience of unity and continuity in the brain, with no strong isomorphism to body morphology. Third, body awareness may be based on efferent/afferent neural signals, suggesting that major body distortions may result from changes in neural sensorimotor experiences. All these views can be supported empirically, suggesting that body awareness is synthesized from multimodal integration and the temporal constancy of multiple body representations. For each of these views, we briefly discuss abnormalities and therapeutic strategies for correcting the bodily distortions in various clinical disorder

Optimising support for informal carers of the long-term disabled to enhance resilience and sustainability

Optimising carer resilience has direct benefits to carers, and additional benefits to the overall care support system by reducing dependence on paid care. Executive summary People with severe and chronic disabilities represent a significant proportion of the population who require assistance to live in their own home and be a part of the community. In addition to assistance from the paid carer workforce, this assistance is provided by family, relatives or friends who are not paid or formally trained in the provision of care and support. These informal carers assist with a variety of tasks including activities of daily living, emotional care and support and accessing medical care and ongoing therapy to optimise independence. There are 2.7 million people in Australia who provide informal (unpaid) care to a person with a disability or long-term health condition, of which 770,000 provide the majority of care and support to people with a severe disability. Given their substantial contribution to care provision and the physical, emotional and other impacts of providing care, it is important to understand the experience of informal carers and address their support needs. In recent years, studies have elucidated the substantial effects of providing care on the psychological, physical, social and other impacts of providing care to a person with a long-term disability. There are a range of interventions to mitigate these impacts, which are provided in Australia through a variety of national and local government and nongovernment entities with varying efficacy. Optimising carer resilience has direct benefits to carers, and additional benefits to the overall care support system by reducing dependence on paid care. This NTRI Forum aims to investigate effective strategies for providing support (excluding skills-related education and training, i.e. manual handling and transfers) to informal carers that can help to optimise their resilience, and the sustainability of the long-term disabled. An evidence review of literature identified 25 relevant reviews and primary studies and a further 16 ongoing primary studies. The overall results of reviews of carer support interventions were inconclusive, therefore firm conclusions regarding what works and doesn’t work cannot be made. However, evidence was reported as ‘good’ for educational and psycho-educational interventions, counselling and psychosocial interventions and multicomponent interventions; Evidence for care co-ordination and family support interventions was described as ‘promising’; Evidence for technology-based interventions was conflicting in the setting of Dementia, but more positive in the area of catastrophic injury; Evidence for respite care was described as ‘not strong’, and although benefits were reported, the importance of additional support strategies in conjunction with respite care was emphasised. Similarly, emerging positive evidence in favour of support groups was reported, however additional concurrent support strategies were recommended. Passive information dissemination alone was found to be ineffective. The review also outlined a range of factors to consider in interpreting this evidence and identified implications for practice and research

Use of robotics in spinal cord injury: a case report.

OBJECTIVE: We examined the use of robotics to treat upper-extremity (UE) dysfunction in tetraplegic patients with spinal cord injury (SCI). METHOD: a 51-yr-old man with incomplete SCI participated in an occupational therapy program that combined traditional occupational therapy with Reo Go®, a comprehensive therapy platform that includes a robotic guide featuring a telescopic arm to enable high repetitions of functionally relevant UE exercises. RESULTS: The participant demonstrated measurable improvements in active range of motion, muscle strength as measured through manual muscle testing, perceived right UE function, and self-care performance as measured by the FIM™. CONCLUSION: The findings from this case are promising and demonstrate the Reo Go\u27s utility in combination with traditional occupational therapy. However, more research and specific protocols that are easily reproducible with robots such as the Reo Go are needed to validate this evolving treatment area
