Remote Follow-Up Technologies in Traumatic Brain Injury: A Scoping Review

Traumatic brain injury (TBI) remains a leading cause of death and disability worldwide. Motivations for outcome data collection in TBI are threefold: to improve patient outcomes, to facilitate research, and to provide the means and methods for wider injury surveillance. Such data play a pivotal role in population health, and ways to increase the reliability of data collection following TBI should be pursued. As a result, technology-aided follow-up of patients with neurotrauma is on the rise; there is, therefore, a need to describe how such technologies have been used. A scoping review was conducted and reported using the PRISMA extension (PRISMA-ScR). Five electronic databases (Embase, MEDLINE, Global Health, PsycInfo, and Scopus) were searched systematically using keywords derived from the concepts of "telemedicine," "TBI," "outcome assessment," and "patient-generated health data." Forty studies described follow-up technologies (FUTs) utilizing telephones (52.5%, n = 21), short message service (SMS; 10%, n = 4), smartphones (22.5%, n = 9), videoconferencing (10%, n = 4), digital assistants (2.5%, n = 1), and custom devices (2.5%, n = 1) among cohorts of patients with TBI of varying injury severity. Where reported, clinical facilitators, remote follow-up timing and intervals between sessions, synchronicity of follow-up instances, proxy involvement, outcome measures utilized, and technology evaluation efforts are described. FUTs can aid more temporally sensitive assessments and capture fluctuating sequelae, a benefit of particular relevance to TBI cohorts. However, the evidence base surrounding FUTs remains in its infancy, particularly with respect to large samples, low- and middle-income patient cohorts, and the validation of outcome measures for deployment via such remote technology.

Remote supervision of rehabilitation interventions for survivors of moderate or severe traumatic brain injury: A scoping review

INTRODUCTION

Individuals with moderate or severe traumatic brain injury (TBI) often have persistent impairments upon discharge home. In rural communities, specialized rehabilitation services to address impairments can be difficult to access. The purpose of this scoping review is to examine how remote supervision is currently being used in TBI rehabilitation to identify gaps in knowledge that need to be addressed to facilitate access to and implementation of these services.

METHODS

The main objective for this review is to identify the methods being used to deliver remote supervision for rehabilitation in a moderate or severe TBI population. The aim of this review was to document the implementation characteristics of remote supervision used including: (1) type of supervision such as synchronous, asynchronous supervision or mixed; (2) frequency and intensity of remote supervision; and (3) outcomes used to measure intervention delivery as well as effectiveness within this population. This scoping review follows EQUATOR Network recommendations for screening and extracting data.

RESULTS

Twenty-six studies using a variety of remote supervision technology and outcome measures were included. Supervision frequency and intensity are poorly reported with no standardization. One hundred and six outcome measures were reported in this review showing large diversity in the areas being explored.

DISCUSSION

Different types of remote supervision have been used with this population; however, there are no clear guidelines on clinical implementation. Future studies must better define implementation parameters of remote supervision. Benefit on physical activity, balance and mobility outcomes also need to be further explored.

Traumatic brain injury education for adult patients and families: a scoping review

Traumatic brain injury (TBI) is increasingly viewed as a chronic condition, bringing long-term needs for patient and caregiver knowledge pertaining to symptom and problem management over time. In light of these needs, we performed a scoping review of the literature on brain injury education provided to adult patients and/ or family members affected by TBI. Objectives were to describe the types of educational interventions that have been developed; to review the effects of these interventions; and to determine gaps that might be filled by future research efforts. Of 88 articles meeting search criteria and subjected to data extraction, 34 concerned education about mild TBI and 54, moderate to severe TBI. Most mild TBI articles focused on education in the Emergency Room, while most moderate/ severe TBI education was directed toward family members/ caregivers and was frequently combined with other treatment components, making the effects of education difficult to discern. Only 1 article incorporated elements of self-management training (SMT), a model proved effective in other chronic health conditions. We recommend further exploration of SMT principles in long-term TBI care, as well as more precise definition of treatment components in all patient and family interventions, so that the specific effects of education and other treatment elements may be more readily evaluated.

Fitness training for cardiorespiratory conditioning after traumatic brain injury

BACKGROUND

Reduced cardiorespiratory fitness (cardiorespiratory deconditioning) is a common consequence of traumatic brain injury (TBI). Fitness training may be implemented to address this impairment.

OBJECTIVES

The primary objective of this updated review was to evaluate whether fitness training improves cardiorespiratory fitness in people who have sustained a TBI. The secondary objectives were to evaluate whether fitness training improves body function and structure (physical and cognitive impairments, psychological responses resulting from the injury), activity limitations and participation restrictions in people who have sustained a TBI as well as to evaluate its safety, acceptance, feasibility and suitability.

SEARCH METHODS

We searched 10 electronic databases (the Cochrane Injuries Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Embase; PubMed (MEDLINE); CINAHL; AMED; SPORTDiscus; PsycINFO; PEDro and PsycBITE) and the International Clinical Trials Registry Platform for relevant trials. In addition we screened reference lists from systematic reviews related to the topic that we identified from our search, and from the included studies, and contacted trialists to identify further studies. The search was run in August 2017.

SELECTION CRITERIA

Randomised controlled studies with TBI participants were eligible if they compared an exercise programme incorporating cardiorespiratory fitness training to usual care, a non-exercise intervention, or no intervention.

DATA COLLECTION AND ANALYSIS

Two authors independently screened the search results, extracted data and assessed bias. We contacted all trialists for additional information. We calculated mean difference (MD) or standardised mean difference (SMD) and 95% confidence intervals (CI) for continuous data, and odds ratio with 95% CI for dichotomous data. We pooled data when there were sufficient studies with homogeneity.

MAIN RESULTS

Two new studies incorporating 96 participants were identified in this update and were added to the six previously included studies. A total of eight studies incorporating 399 participants are included in the updated review. The participants were primarily men aged in their mid-thirties who had sustained a severe TBI. No studies included children. The studies were clinically diverse with regard to the interventions, time postinjury and the outcome measures used. At the end of intervention, the mean difference in peak power output was 35.47 watts (W) in favour of fitness training (MD 35.47 W, 95% CI 2.53 to 68.41 W; 3 studies, 67 participants; low-quality evidence). The CIs include both a possible clinically important effect and a possible negligible effect, and there was moderate heterogeneity among the studies.Five of the secondary outcomes had sufficient data at the end of intervention to enable meta-analysis: body composition (SMD 0.29 standard deviations (favouring control), 95% CI -0.22 to 0.79; 2 studies, 61 participants; low-quality evidence), strength (SMD -0.02 (favouring control), 95% CI -0.86 to 0.83; 2 studies, 23 participants; very low-quality evidence), fatigue (SMD -0.32 (favouring fitness training), 95% CI -0.90 to 0.26; 3 studies, 130 participants; very low-quality evidence), depression (SMD -0.43 (favouring fitness training), 95% CI -0.92 to 0.06; 4 studies, 220 participants; very low-quality evidence), and neuromotor function (MD 0.01 m (favouring fitness training), 95% CI -0.25 to 0.27; 2 studies, 109 participants; moderate-quality evidence). It was uncertain whether fitness training was more or less effective at improving these secondary outcomes compared to the control interventions. Quality of life was assessed in three trials, but we did not pool the data because of substantial heterogeneity. Five of the eight included studies had no dropouts from their intervention group and no adverse events were reported in any study.

AUTHORS' CONCLUSIONS

There is low-quality evidence that fitness training is effective at improving cardiorespiratory deconditioning after TBI; there is insufficient evidence to draw any definitive conclusions about the other outcomes. Whilst the intervention appears to be accepted by people with TBI, and there is no evidence of harm, more adequately powered and well-designed studies are required to determine a more precise estimate of the effect on cardiorespiratory fitness, as well as the effects across a range of important outcome measures and in people with different characteristics (e.g. children). In the absence of high quality evidence, clinicians may be guided by pre-exercise screening checklists to ensure the person with traumatic brain injury is safe to exercise, and set training parameters using guidelines established by the American College of Sports Medicine for people who have suffered a brain injury.

Interdisciplinary eHealth for the care of people living with traumatic brain injury: A systematic review

OBJECTIVE

To identify literature which discusses the barriers and enablers of eHealth technology and which evaluates its role in facilitating interdisciplinary team work for the care of people with a traumatic brain injury (TBI).

DESIGN

Systematic review.

DATA SOURCES

Studies were identified by searching CINAHL, Embase, Medline, PsycINFO, Scopus, and Web of Science.

STUDY SELECTION

Studies included in the review were required to feature an eHealth intervention which assisted interdisciplinary care for people with TBI.

DATA EXTRACTION

Descriptive data for each study described the eHealth intervention, interdisciplinary team, outcomes, and barriers and facilitators in implementing eHealth interventions.

RESULTS

The search resulted in 1389 publications, of which 35 were retrieved and scanned in full. Six studies met all the inclusion criteria for the review. Four different eHealth interventions were identified: (i) an electronic goals systems, (ii) telerehabilitation, (iii) videoconferencing, and (iv) a point-of-care team-based information system. Various barriers and facilitators were identified in the use of eHealth.

CONCLUSION

eHealth interventions have been reported to support interdisciplinary teams for the care of TBI. However, there is a substantial gap in existing literature regarding the barriers and enablers which characterize a successful interdisciplinary eHealth model for people with TBI.

Is telemonitoring useful for supporting persons with consciousness disorders and caregivers? A preliminary observational study in a real-life population

Introduction

Preliminary evidences showed that telemedicine may allow a reduction of costs and an enhancement of patients’ satisfaction and quality of life (QoL), with the same effectiveness of conventional methods of healthcare delivery. Literature is quite absent in relation to the use of telemedicine for patients with disorders of consciousness (DoC) whose management is delegated almost entirely to the family. In order to promote an alternative setting to manage persons affected by DoC, also supporting their families, a pilot project was designed to test the feasibility of home-care assistance based on a system of telemonitoring.

Methods

In total, 11 patients were supported by a telemonitoring system via a workstation installed at the patients’ homes. All patients underwent a clinical and functional evaluation at enrolment, after two months, after six months and at the end of the project, after 12 months by means of clinical scales (Glasgow Coma Scale, Rancho Los Amigos Levels of Cognitive Functioning Scale, Glasgow Outcome Scale, Disability Rating Scale), while the World Health Organization (WHO) QoL, the Hamilton Depression Rating Scale, the Hamilton Anxiety Rating Scale and a satisfaction score were completed by caregivers.

Results

Patients’ scores at the clinical scales did not show statistically significant differences from T0 to T3. A trend toward the improvement of caregivers’ QoL, anxiety and depression, as well as a high degree of satisfaction with regard to the intervention, were reported. The economic evaluation showed an average cost/day for a patient of about €70.

Discussion

Preliminary data suggest that the use of telemonitoring services in the management of persons affected by DoC is feasible and well accepted by caregivers, with a potential positive effect on their mood and QoL. Therefore, telemonitoring should be considered in the management of DoC patients to favour discharge from acute care and to support families in home care.

Multi-disciplinary rehabilitation for acquired brain injury in adults of working age

BACKGROUND

Evidence from systematic reviews demonstrates that multi-disciplinary rehabilitation is effective in the stroke population, in which older adults predominate. However, the evidence base for the effectiveness of rehabilitation following acquired brain injury (ABI) in younger adults has not been established, perhaps because this scenario presents different methodological challenges in research.

OBJECTIVES

To assess the effects of multi-disciplinary rehabilitation following ABI in adults 16 to 65 years of age.

SEARCH METHODS

We ran the most recent search on 14 September 2015. We searched the Cochrane Injuries Group Specialised Register, The Cochrane Library, Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), Embase Classic+Embase (OvidSP), Web of Science (ISI WOS) databases, clinical trials registers, and we screened reference lists.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing multi-disciplinary rehabilitation versus routinely available local services or lower levels of intervention; or trials comparing an intervention in different settings, of different intensities or of different timing of onset. Controlled clinical trials were included, provided they met pre-defined methodological criteria.

DATA COLLECTION AND ANALYSIS

Three review authors independently selected trials and rated their methodological quality. A fourth review author would have arbitrated if consensus could not be reached by discussion, but in fact, this did not occur. As in previous versions of this review, we used the method described by Van Tulder 1997 to rate the quality of trials and to perform a 'best evidence' synthesis by attributing levels of evidence on the basis of methodological quality. Risk of bias assessments were performed in parallel using standard Cochrane methodology. However, the Van Tulder system provided a more discriminative evaluation of rehabilitation trials, so we have continued to use it for our primary synthesis of evidence. We subdivided trials in terms of severity of brain injury, setting and type and timing of rehabilitation offered.

MAIN RESULTS

We identified a total of 19 studies involving 3480 people. Twelve studies were of good methodological quality and seven were of lower quality, according to the van Tulder scoring system. Within the subgroup of predominantly mild brain injury, 'strong evidence' suggested that most individuals made a good recovery when appropriate information was provided, without the need for additional specific interventions. For moderate to severe injury, 'strong evidence' showed benefit from formal intervention, and 'limited evidence' indicated that commencing rehabilitation early after injury results in better outcomes. For participants with moderate to severe ABI already in rehabilitation, 'strong evidence' revealed that more intensive programmes are associated with earlier functional gains, and 'moderate evidence' suggested that continued outpatient therapy could help to sustain gains made in early post-acute rehabilitation. The context of multi-disciplinary rehabilitation appears to influence outcomes. 'Strong evidence' supports the use of a milieu-oriented model for patients with severe brain injury, in which comprehensive cognitive rehabilitation takes place in a therapeutic environment and involves a peer group of patients. 'Limited evidence' shows that specialist in-patient rehabilitation and specialist multi-disciplinary community rehabilitation may provide additional functional gains, but studies serve to highlight the particular practical and ethical restraints imposed on randomisation of severely affected individuals for whom no realistic alternatives to specialist intervention are available.

AUTHORS' CONCLUSIONS

Problems following ABI vary. Consequently, different interventions and combinations of interventions are required to meet the needs of patients with different problems. Patients who present acutely to hospital with mild brain injury benefit from follow-up and appropriate information and advice. Those with moderate to severe brain injury benefit from routine follow-up so their needs for rehabilitation can be assessed. Intensive intervention appears to lead to earlier gains, and earlier intervention whilst still in emergency and acute care has been supported by limited evidence. The balance between intensity and cost-effectiveness has yet to be determined. Patients discharged from in-patient rehabilitation benefit from access to out-patient or community-based services appropriate to their needs. Group-based rehabilitation in a therapeutic milieu (where patients undergo neuropsychological rehabilitation in a therapeutic environment with a peer group of individuals facing similar challenges) represents an effective approach for patients requiring neuropsychological rehabilitation following severe brain injury. Not all questions in rehabilitation can be addressed by randomised controlled trials or other experimental approaches. For example, trial-based literature does not tell us which treatments work best for which patients over the long term, and which models of service represent value for money in the context of life-long care. In the future, such questions will need to be considered alongside practice-based evidence gathered from large systematic longitudinal cohort studies conducted in the context of routine clinical practice.

Postacute Programming for Community Integration: A Scoping Review

There has been a dramatic increase in recent years in the literature available on community integration among people with acquired brain injuries. At the same time, however, clinicians are calling for information that has utility in the complex environment of community practice. The study was a scoping review to address the question:What is known from the existing literature regarding the best ways to promote community integration in the postacute phase of brain injury recovery?From a preliminary pool of 925 studies identified by electronic searching of 5 databases in a 15-year time window, a final set of 30 was selected for further review, referring to 25 distinct programs. This scoping review has shown that there are 5 types of programs typically offered to survivors of brain injuries to assist with community integration: supported employment, traditional rehabilitation, environmental adaptation, support development and transitional living. These 5 approaches were primarily used to address 2 aspects of community integration: traditional rehabilitation was most commonly used to promote independent living, and supported employment was the most common approach used to promote productive occupation. Themes that emerged from the review were the need for highly individualised programming, in vivo approaches, tailored supports, early intervention and a focus on participation. Methodologically, the study represents an important acknowledgment of the valuable information that is available in the literature in descriptive and small sample research.

Context-sensitive Cognitive Rehabilitation after Brain Injury: Theory and Practice

The goal of this article is to describe and offer a rationale for an approach to cognitive rehabilitation labelled “context sensitive”. This approach stands in contrast to the modern tradition of cognitive rehabilitation that features massed and decontextualized process-specific cognitive exercises. The paper begins with theoretical considerations, emphasises the history of research in transfer of cognitive skill, incorporates the World Health Organization framework, describes context-sensitive apprenticeship procedures, draws on evidence accumulated over several decades with related disability groups, and ends with answers to frequently asked questions.

Evidence of benefit from telerehabilitation in routine care: a systematic review

We systematically reviewed the evidence on the effectiveness of telerehabilitation (TR) applications. The review included reports on rehabilitation for any disability, other than mental health conditions, and drug or alcohol addiction. All forms of telecommunications technology for TR and all types of study design were considered. Study quality was assessed using an approach that considered both study performance and study design. Judgements were made on whether each TR application had been successful, whether reported outcomes were clinically significant, and whether further data were needed to establish the application as suitable for routine use. Sixty-one scientifically credible studies that reported patient outcomes or administrative changes were identified through computerized literature searches on five databases. Twelve clinical categories were covered by the studies. Those dealing with cardiac or neurological rehabilitation were the most numerous. Thirty-one of the studies (51%) were of high or good quality. Study results showed that 71% of the TR applications were successful, 18% were unsuccessful and for 11% the status was unclear. The reported outcomes for 51% of the applications appeared to be clinically significant. Poorer-quality studies tended to have worse outcomes than those from high- or good-quality studies. We judged that further study was required for 62% of the TR applications and desirable for 23%. TR shows promise in many fields, but compelling evidence of benefit and of impact on routine rehabilitation programmes is still limited. There is a need for more detailed, better-quality studies and for studies on the use of TR in routine care.

A home programme for patients with cognitive dysfunction: a pilot study

OBJECTIVE

To evaluate the effectiveness of a 12-week individualized home programme of rehabilitation for patients with cognitive impairment.

METHODS

Six patients with cognitive dysfunction, after haemorrhagic stroke, participated in this study. A programme was carried out in the home environment that consisted of four mixed training programmes: cognitive remediation therapy, story retelling, cognitive enhancing games and aerobic exercise. The patients performed the home programme for 2 hours a day, 7 days a week, for 12 weeks. The main outcomes were measured using the MMSE, Neurobehavioural Cognitive Status Examination (NCSE), domain-specific computerized neuropsychological test for attention, memory and executive function, the Lowenstein Occupational Therapist Cognitive Assessment (LOTCA), the Modified Barthel Index (MBI) and the Seoul-Instrumental Activity of Daily Living (S-IADL).

RESULTS

After completion of a 12-week home programme, the patients' S-IADL scores improved significantly (p < 0.05). The patients' MMSE and NCSE scores improved marginally, with mean score changes of 4.2 (p = 0.058), 4.7 (p = 0.078) and 6.8 (p = 0.068) points, respectively. However, the patients' domain-specific cognitive test and LOTCA scores did not significantly change.

CONCLUSION

The results of this study showed that an individualized home programme improved IADL performance in patients with cognitive dysfunction and may have a beneficial effect on cognition, as assessed by general cognitive measures.

Enhancing quality of life through telerehabilitation

Telerehabilitation is an emerging method of delivering rehabilitation services that uses technology to serve clients, clinicians, and systems by minimizing the barriers of distance, time, and cost. The driving force for telerehabilitation has been as an alternative to face-to-face rehabilitation approaches to reduce costs, increase geographic accessibility, or act as a mechanism to extend limited resources. A rationale for telerehabilitation is the potential to enhance outcomes beyond what may result from face-to-face interventions by enabling naturalistic, in vivo interventions. There is considerable support for the value of interventions delivered in the natural environment, ranging from addressing efficacy concerns by addressing problems of generalization, to increasing patient participation, including environmental context in rehabilitation, and increasing patient satisfaction. Further clinical and research exploration should explore telerehabilitation as a tool for the delivery of rehabilitation services in vivo.

Physical exercise and cognitive recovery in acquired brain injury: a review of the literature

OBJECTIVE

Physical exercise has been shown to play an ever-broadening role in the maintenance of overall health and has been implicated in the preservation of cognitive function in both healthy elderly and demented populations. Animal and human studies of acquired brain injury (ABI) from trauma or vascular causes also suggest a possible role for physical exercise in enhancing cognitive recovery.

DATA SOURCES

A review of the literature was conducted to explore the current understanding of how physical exercise impacts the molecular, functional, and neuroanatomic status of both intact and brain-injured animals and humans.

STUDY SELECTION

Searches of the MEDLINE, CINHAL, and PsychInfo databases yielded an extensive collection of animal studies of physical exercise in ABI. Animal studies strongly tie physical exercise to the upregulation of multiple neural growth factor pathways in brain-injured animals, resulting in both hippocampal neurogenesis and functional improvements in memory.

DATA EXTRACTION

A search of the same databases for publications involving physical exercise in human subjects with ABI yielded 24 prospective and retrospective studies.

DATA SYNTHESIS

Four of these evaluated cognitive outcomes in persons with ABI who were involved in physical exercise. Three studies cited a positive association between exercise and improvements in cognitive function, whereas one observed no effect. Human exercise interventions varied greatly in duration, intensity, and level of subject supervision, and tools for assessing neurocognitive changes were inconsistent.

CONCLUSIONS

There is strong evidence in animal ABI models that physical exercise facilitates neurocognitive recovery. Physical exercise interventions are safe in the subacute and rehabilitative phases of recovery for humans with ABI. In light of strong evidence of positive effects in animal studies, more controlled, prospective human interventions are warranted to better explore the neurocognitive effects of physical exercise on persons with ABI.

‘Participate to learn’: A promising practice for community ABI rehabilitation

OBJECTIVE

To identify best practices and promising practices to enhance participation in meaningful and productive activities.

METHOD

An electronic search of the ABI rehabilitation research literature since 1990 yielded 974 articles of which 30 focused on interventions that targeted participation and evaluated effectiveness using direct measures of participation. Three reviewers rated these articles according to the standards set out by the Centre for Reviews and Dissemination. Following the systematic review, an interpretive review of the same articles was completed.

RESULTS

Only three studies were rated as strong. No best practices were identified. Three promising practices found some support. The interpretive review suggested 'Participate to learn' as a useful rehabilitation model. The model rests on roles as goals, learning by experience in real-life contexts and the use of personal and environmental support to enable participation.

CONCLUSIONS

'Participate to learn' is both a credible rehabilitation model and deserving of more study.

Characteristics of home-based community integration programmes for adults with brain injury

OBJECTIVES

To conduct a nationwide telephone survey in order to gather data on some of the quantifiable characteristics of home-based community integration programmes available in the US to adults with brain injury.

DESIGN

Survey.

METHODS

The Community Integration Programme Questionnaire (CIPQ) was used to interview 13 home-based community integration programmes. This study then used descriptive statistics to analyse the characteristics of the programmes.

OUTCOME

There was a good deal of variability in client and programmatic characteristics.

CONCLUSIONS

There is considerable variability in characteristics among home-based community integration programmes.

Fitness training for cardiorespiratory conditioning after traumatic brain injury

BACKGROUND

Cardiorespiratory deconditioning is a common sequelae after traumatic brain injury (TBI). Clinically, fitness training is implemented to address this impairment, however this intervention has not been subject to rigorous review.

OBJECTIVES

The primary objective was to evaluate whether fitness training improves cardiorespiratory fitness in people who have sustained a TBI.

SEARCH STRATEGY

We searched ten electronic databases (Cochrane Injuries Group Trials Register; Cochrane Central Register of Controlled Trials (CENTRAL); EMBASE; PubMed (MEDLINE); CINAHL; AMED; SPORTDiscus; PsycINFO; PEDro and PsycBITE) and two clinical trials registers (TrialsCentral and Current Controlled Trials). The last search was August 2007. In addition we screened reference lists from included studies and contacted trialists to identify further studies.

SELECTION CRITERIA

Randomised controlled studies with TBI participants were eligible if they compared an exercise programme incorporating cardiorespiratory fitness training to usual care, a non-exercise intervention or no intervention.

DATA COLLECTION AND ANALYSIS

Two authors independently screened the search output, extracted data and assessed quality. All trialists were contacted for additional information. Mean difference and 95% confidence intervals (CI) were calculated for continuous data and risk difference or odds ratio and 95% CI were calculated for dichotomous data. Data were pooled when there were sufficient studies with clinical and statistical homogeneity.

MAIN RESULTS

Six studies, incorporating 303 participants, were included. The participants were primarily males, in their mid thirties who had sustained a severe TBI. The studies were clinically diverse with regard to the interventions, time post-injury and the outcome measures used; therefore, the primary outcome could not be pooled. Three of the six studies indirectly assessed change in cardiorespiratory fitness after fitness training using the peak power output obtained during cycle ergometry (either at volitional fatigue or at a predetermined endpoint, that is, a percentage of predicted heart rate maximum). Cardiorespiratory fitness was improved after fitness training in one study (mean difference 59 watts, 95% CI 24 to 94), whilst there was no significant improvement in the other two studies. Four of the six studies had no drop-outs from their intervention group and no adverse events were reported in any study.

AUTHORS' CONCLUSIONS

There is insufficient evidence to draw any definitive conclusions about the effects of fitness training on cardiorespiratory fitness. Whilst it appears to be a safe and accepted intervention for people with TBI, more adequately powered and well-designed studies are required to determine the effects across a range of outcome measures.

A randomized trial of modafinil for the treatment of fatigue and excessive daytime sleepiness in individuals with chronic traumatic brain injury

BACKGROUND

This study examines the efficacy of modafinil in treating fatigue and excessive daytime sleepiness in individuals with traumatic brain injury (TBI).

METHODS

A single-center, double-blind, placebo-controlled cross-over trial, where 53 participants with TBI were randomly assigned to receive up to 400 mg of modafinil, or equal number of inactive placebo tablets. Main eligibility criteria were being at least 1 year post-TBI severe enough to require inpatient rehabilitation. The primary outcome measures were fatigue (Fatigue Severity Scale, FSS) and daytime sleepiness (Epworth Sleepiness Scale, ESS).

RESULTS

After adjusting for baseline scores and period effects, there were no statistically significant differences between improvements seen with modafinil and placebo in the FSS at week 4 (-0.5 +/- 1.88; P = .80) or week 10 (-1.4 +/- 2.75; P = .61). For ESS, average changes were significantly greater with modafinil than placebo at week 4 (-1.2 +/- 0.49; P = .02) but not at week 10 (-0.5 +/- 0.87; P = .56). Modafinil was safe and well tolerated, although insomnia was reported significantly more often with modafinil than placebo (P = .03).

CONCLUSIONS

While there were sporadic statistically significant differences identified, a clear beneficial pattern from modafinil was not seen at either week 4 or week 10 for any of the 12 outcomes. There was no consistent and persistent clinically significant difference between treatment with modafinil and placebo.

Reflecting on a self-care process in the home setting for traumatic brain injury survivors

An estimated 5.3 million Americans are living with disabilities from traumatic brain injuries. Traumatic brain injury (TBI) can cause a wide range of functional changes affecting thinking, emotions, and behaviors, or a combination of any of these. Reflecting on a self-care process for patients in TBI home rehabilitation programs becomes critical for nurses who desire to optimize patient functioning. As the young patients' brain plasticity impacts adjustments to deficits and injury, applying the self-care process in the home setting provides a natural healing environment. As TBI survivors recognize and regulate their own behaviors, application of nursing actions dynamically match this change.

Carers' perspective on respite for persons with acquired brain injury

Persons with acquired brain injury require continuing care and support in various aspects of their lives. Although the care and support are predominantly provided by family members, little is known about the respite that these carers require to continue the care on a daily basis. This study aims to address the lack of data on respite care and people with acquired brain injury from the perspective of carers. Survey methodology was used to gather information from carers who were members of a peak brain injury association in New South Wales, Australia. The responses of 85 carers were analysed using logistic regression and frequency counts. The characteristics of carers were consistent with the research literature on respite and acquired brain injury, with carers being mainly female and there being a reliance on an informal network to assist in the care. Carers also reported that caring prevented them from obtaining gainful employment. Several factors were significantly associated with the use of respite, these were carers' single marital status; and the person with acquired brain injury's severity of disability, high level of dependency and number of days spent in coma. Carers also reported other factors that might influence them to use respite and they identified their expectations of respite. This study highlights carers' perspective on respite that is an under-researched area in acquired brain injury and reiterates ongoing need for respite.

Benefits and challenges of providing transitional rehabilitation services to people with spinal cord injury from regional, rural and remote locations

OBJECTIVE

To identify the factors influencing participation and outline the benefits and challenges of providing transitional rehabilitation for people with spinal cord injury (SCI) from rural and regional locations.

DESIGN

Grounded Theory analysis of service records and policy documents.

SETTING

One transitional rehabilitation service for people with SCI.

PARTICIPANTS

Service records of 40 individuals with SCI from non-metropolitan locations who participated in transitional rehabilitation and 29 individuals with SCI who declined transitional rehabilitation over a two-year period.

INTERVENTIONS

Home-based transitional rehabilitation programs offered by a multidisciplinary team including physiotherapy, occupational therapy, nursing and social work.

MEASURES

Participation was measured using the percentage of people from non-metropolitan locations who decline transitional rehabilitation. The benefits and challenges of transitional rehabilitation were identified using open, axial and selective coding of service records.

RESULTS

People with SCI from non-metropolitan areas were underrepresented among transitional rehabilitation participants, with 69% of those declining transitional rehabilitation coming from regional or rural areas. The study identified five functions of transitional rehabilitation that presented both benefits and challenges of this model in assisting people from non-metropolitan locations. These included: (1) the identification, education, coordination and funding of local care providers; (2) family involvement in rehabilitation; (3) contact with social and community supports; (4) specialist support to problem-solve discharge needs; and (5) skill acquisition and transfer in a community environment.

CONCLUSIONS

The transitional rehabilitation model offers many advantages over traditional hospital-based rehabilitation but still faces challenges in offering an equitable model for people with SCI from non-metropolitan locations.

Telephone follow-up, initiated by a hospital-based health professional, for postdischarge problems in patients discharged from hospital to home

BACKGROUND

It is known that many patients encounter a variety of problems in the first weeks after they have been discharged from hospital to home. In recent years many projects have addressed discharge planning, with the aim of reducing problems after discharge. Telephone follow-up (TFU) is seen as a good means of exchanging information, providing health education and advice, managing symptoms, recognising complications early, giving reassurance and providing quality aftercare service. Some research has shown that telephone follow-up is feasible, and that patients appreciate such calls. However, at present it is not clear whether TFU is also effective in reducing postdischarge problems.

OBJECTIVES

To assess the effects of follow-up telephone calls in the first month post discharge, initiated by hospital-based health professionals, to patients discharged from hospital to home.

SEARCH STRATEGY

We searched the following databases from their start date to July 2003, without limits as to date of publication or language: the Cochrane Consumers and Communication Review Group's Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), PubMed, EMBASE (OVID), BiomedCentral, CINAHL, ERIC (OVID), INVERT (Dutch nursing literature index), LILACS, Picarta (Dutch library system), PsycINFO/PsycLIT (OVID), the Combined Social and Science Citation Index Expanded (SCI-E), SOCIOFILE. We searched for ongoing research in the following databases: National Research Register (http://www.update-software.com/nrr/); Controlled Clinical Trials (http://www.controlled-trials.com/); and Clinical Trials (http://clinicaltrials.gov/). We searched the reference lists of included studies and contacted researchers active in this area.

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials of TFU initiated by a hospital-based health professional, for patients discharged home from an acute hospital setting. The intervention was delivered within the first month after discharge; outcomes were measured within 3 months after discharge, and either the TFU was the only intervention, or its effect could be analysed separately.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for inclusion and for methodological quality. The methodological quality of included studies was assessed using the criteria from the Cochrane Effective Practice and Organisation of Care Review Group. The data-extraction form was based on the template developed by the Cochrane Consumers and Communication Review Group. Data was extracted by one review author and checked by a second author. For as far it was considered that there was enough clinical homogeneity with regard to patient groups and measured outcomes, statistical pooling was planned using a random effects model and standardised mean differences for continuous scales and relative risks for dichotomous data, and tests for statistical heterogeneity were performed.

MAIN RESULTS

We included 33 studies involving 5110 patients. Predominantly, the studies were of low methodological quality. TFU has been applied in many patient groups. There is a large variety in the ways the TFU was performed (the health professionals who undertook the TFU, frequency, structure, duration, etc.). Many different outcomes have been measured, but only a few were measured across more than one study. Effects are not constant across studies, nor within patient groups. Due to methodological and clinical diversity, quantitative pooling could only be performed for a few outcomes. Of the eight meta-analyses in this review, five showed considerable statistical heterogeneity. Overall, there was inconclusive evidence about the effects of TFU.

AUTHORS' CONCLUSIONS

The low methodological quality of the included studies means that results must be considered with caution. No adverse effects were reported. Nevertheless, although some studies find that the intervention had favourable effects for some outcomes, overall the studies show clinically-equivalent results between TFU and control groups. In summary, we cannot conclude that TFU is an effective intervention.

Evidence-based cognitive rehabilitation: updated review of the literature from 1998 through 2002

OBJECTIVE

To update the previous evidence-based recommendations of the Brain Injury Interdisciplinary Special Interest Group of the American Congress of Rehabilitation Medicine for cognitive rehabilitation of people with traumatic brain injury (TBI) and stroke, based on a systematic review of the literature from 1998 through 2002.

DATA SOURCES

PubMed and Infotrieve literature searches were conducted using the terms attention, awareness, cognition, communication, executive, language, memory, perception, problem solving, and reasoning combined with each of the terms rehabilitation, remediation, and training. Reference lists from identified articles were reviewed and a bibliography listing 312 articles was compiled.

STUDY SELECTION

One hundred eighteen articles were initially selected for inclusion. Thirty-one studies were excluded after detailed review. Excluded articles included 14 studies without data, 6 duplicate publications or follow-up studies, 5 nontreatment studies, 4 reviews, and 2 case studies involving diagnoses other than TBI or stroke.

DATA EXTRACTION

Articles were assigned to 1 of 7 categories reflecting the primary area of intervention: attention; visual perception; apraxia; language and communication; memory; executive functioning, problem solving and awareness; and comprehensive-holistic cognitive rehabilitation. Articles were abstracted and levels of evidence determined using specific criteria.

DATA SYNTHESIS

Of the 87 studies evaluated, 17 were rated as class I, 8 as class II, and 62 as class III. Evidence within each area of intervention was synthesized and recommendations for practice standards, practice guidelines, and practice options were made.

CONCLUSIONS

There is substantial evidence to support cognitive-linguistic therapies for people with language deficits after left hemisphere stroke. New evidence supports training for apraxia after left hemisphere stroke. The evidence supports visuospatial rehabilitation for deficits associated with visual neglect after right hemisphere stroke. There is substantial evidence to support cognitive rehabilitation for people with TBI, including strategy training for mild memory impairment, strategy training for postacute attention deficits, and interventions for functional communication deficits. The overall analysis of 47 treatment comparisons, based on class I studies included in the current and previous review, reveals a differential benefit in favor of cognitive rehabilitation in 37 of 47 (78.7%) comparisons, with no comparison demonstrating a benefit in favor of the alternative treatment condition. Future research should move beyond the simple question of whether cognitive rehabilitation is effective, and examine the therapy factors and patient characteristics that optimize the clinical outcomes of cognitive rehabilitation.

Multi-disciplinary rehabilitation for acquired brain injury in adults of working age

BACKGROUND

Evidence from systematic reviews demonstrates that multi-disciplinary rehabilitation is effective in the stroke population, where older adults predominate. However, the evidence base for the effectiveness of rehabilitation following acquired brain injury (ABI) in younger adults is not yet established, perhaps because there are different methodological challenges.

OBJECTIVES

To assess the effects of multi-disciplinary rehabilitation following ABI in adults, 16 to 65 years. To explore approaches that are effective in different settings and the outcomes that are affected.

SEARCH STRATEGY

We used a wide range of sources including: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (1966-2004), EMBASE (1988-2004), CINAHL (1983-2004), PsycLIT (1967-2004), AMED, the National Research Register 2004 and ISI Science Citation Index (1981-2004).

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing multi-disciplinary rehabilitation with either routinely available local services or lower levels of intervention; or trials comparing intervention in different settings or at different levels of intensity. Quasi-randomised and quasi-experimental designs were also included, providing they met pre-defined methodological criteria.

DATA COLLECTION AND ANALYSIS

Trials were selected by two authors independently, and their methodological quality rated, again by two independent authors. A third reviewer arbitrated when disagreements could not be resolved by discussion. A 'best evidence' synthesis was performed by attributing levels of evidence, based on methodological quality. Trials were sub-divided in terms of severity of ABI and the setting and type of rehabilitation offered.

MAIN RESULTS

Ten trials were identified of good methodological quality and four of lower quality. Within the subgroup of predominantly mild brain injury, 'strong evidence' suggested that most patients make a good recovery with provision of appropriate information, without additional specific intervention. For moderate to severe injury, there is 'strong evidence' of benefit from formal intervention. For patients with moderate to severe ABI already in rehabilitation, there is strong evidence that more intensive programmes are associated with earlier functional gains, and 'moderate evidence' that continued outpatient therapy can help to sustain gains made in early post-acute rehabilitation. There is 'limited evidence' that specialist in-patient rehabilitation and specialist multi-disciplinary community rehabilitation may provide additional functional gains, but the studies serve to highlight the particular practical and ethical restraints on randomisation of severely affected individuals for whom there are no realistic alternatives to specialist intervention.

AUTHORS' CONCLUSIONS

Problems following ABI vary; different services are required to suit the needs of patients with different problems. Patients presenting acutely to hospital with moderate to severe brain injury should be routinely followed up to assess their need for rehabilitation. Intensive intervention appears to lead to earlier gains. The balance between intensity and cost-effectiveness has yet to be determined. Patients discharged from in-patient rehabilitation should have access to out-patient or community-based services appropriate to their needs. Those with milder brain injury benefit from follow-up, and appropriate information and advice. Not all questions in rehabilitation can be addressed by traditional research methodologies. There are important questions still to be answered and future research should employ the most appropriate methodology.

The usefulness of quantitative EEG (QEEG) and neurotherapy in the assessment and treatment of post-concussion syndrome

Mild traumatic brain injury (TBI) is associated with damage to frontal, temporal and parietal lobes. Post-concussion syndrome has been used to describe a range of residual symptoms that persist 12 months or more after the injury, often despite a lack of evidence of brain abnormalities on MRI and CT scans. The core deficits of post-concussion syndrome are similar to those of ADHD and mood disorders, and sufferers often report memory, socialization problems and frequent headaches. While cognitive rehabilitation and psychological support are widely used, neither has been shown to be effective in redressing the core deficits of post-concussion syndrome. On the other hand, quantitative EEG has been shown to be highly sensitive (96%) in identifying post-concussion syndrome, and neurotherapy has been shown in a number of studies to be effective in significantly improving or redressing the symptoms of post-concussion syndrome, as well as improving similar symptoms in non-TBI patients.
