Efficacy and acceptability of a home-based, family-inclusive intervention for veterans with TBI: A randomized controlled trial

OBJECTIVE

Traumatic brain injury (TBI) often undermines community re-integration, impairs functioning and produces other symptoms. This study tested an innovative programme for veterans with TBI, the Veterans' In-home Programme (VIP), delivered in veterans' homes, involving a family member and targeting the environment (social and physical) to promote community re-integration, mitigate difficulty with the most troubling TBI symptoms and facilitate daily functioning.

SETTING

Interviews and intervention sessions were conducted in homes or by telephone.

PARTICIPANTS

Eighty-one veterans with TBI at a VA polytrauma programme and a key family member.

DESIGN

This was a 2-group randomized controlled trial. Control-group participants received usual-care enhanced by two attention-control telephone calls. Follow-up interviews occurred up to 4 months after baseline interview.

MAIN MEASURES

VIP's efficacy was evaluated using measures of community re-integration, target outcomes reflecting veterans' self-identified problems and self-rated functional competence.

RESULTS

At follow-up, VIP participants had significantly higher community re-integration scores and less difficulty managing targeted outcomes, compared to controls. Self-rated functional competence did not differ between groups. In addition, VIP's acceptability was high.

CONCLUSION

A home-based, family-inclusive service for veterans with TBI shows promise for improving meaningful outcomes and warrants further research and clinical application.

Changes in aspects of social functioning depend upon prior changes in neurodisability in people with acquired brain injury undergoing post-acute neurorehabilitation

Post-acute community-based rehabilitation is effective in reducing disability. However, while social participation and quality of life are valued as distal outcomes of neurorehabilitation, it is often not possible to observe improvements on these outcomes within the limited time-frames used in most investigations of rehabilitation. The aim of the current study was to examine differences in the sequence of attainments for people with acquired brain injury (ABI) undergoing longer term post-acute neurorehabilitation. Participants with ABI who were referred to comprehensive home and community-based neurorehabilitation were assessed at induction to service, at 6 months and again at 1.5 years while still in service on the Mayo-Portland Adaptability Index (MPAI-4), Community Integration Questionnaire, Hospital Anxiety and Depression Scale, and World Health Organisation Quality of Life measure. At 6 months post-induction to service, significant differences were evident in MPAI abilities, adjustment, and total neurodisability; and in anxiety and depression. By contrast, there was no significant effect at 6 months on more socially oriented features of experience namely quality of life (QoL), Community Integration and Participation. Eighteen month follow-up showed continuation of the significant positive effects with the addition of QoL-related to physical health, Psychological health, Social aspects of QoL and Participation at this later time point. Regression analyses demonstrated that change in QoL and Participation were dependent upon prior changes in aspects of neurodisability. Age, severity or type of brain injury did not significantly affect outcome. Results suggest that different constructs may respond to neurorehabilitation at different time points in a dose effect manner, and that change in social aspects of experience may be dependent upon the specific nature of prior neurorehabilitation attainments.

Feasibility and results of a case study of yoga to improve physical functioning in people with chronic traumatic brain injury

PURPOSE

The purpose of this mixed-methods case study was to investigate whether an 8-week 1:1 yoga program was feasible and beneficial to people with traumatic brain injury (TBI).

METHOD

This was a mixed-methods case study of one-to-one yoga for people with TBI included three people. We completed assessments before and after the 8-week yoga intervention and included measures of balance, balance confidence, pain, range of motion, strength and mobility. Qualitative interviews were included at the post-assessment. We include a percent change calculation and salient quotes that represent the perceived impact of the yoga intervention.

RESULTS

All participants completed the yoga intervention and all demonstrated improvements in physical outcome measures. For the group, balance increased by 36%, balance confidence by 39%, lower extremity strength by 100% and endurance by 105%. Qualitative data support the use of yoga to improve multiple aspects of physical functioning, one participant stated: "I mean it's rocked my world. It's changed my life. I mean all the different aspects. I mean physically, emotionally, mentally, it's given me you know my life back…".

CONCLUSIONS

Yoga, delivered in a one-to-one setting, appears to be feasible and beneficial to people with chronic TBI.

IMPLICATIONS FOR REHABILITATION

Chronic traumatic brain injury (TBI) leads to many aspects of physical functioning impairment. Yoga delivered in a one-to-one setting may be feasible and beneficial for people with chronic TBI.

Psychological intervention for improving cognitive function in cancer survivors: a literature review and randomized controlled trial

Although the impact of cancer and associated treatments on cognitive functioning is becoming an increasingly recognized problem, there are few published studies that have investigated psychological interventions to address this issue. A waitlist randomized controlled trial methodology was used to assess the efficacy of a group cognitive rehabilitation intervention ("ReCog") that successfully targeted cancer-related cognitive decline in previously published pilot research. Participants were 29 cancer survivors who were randomly allocated to either the intervention group or a waitlist group who received the intervention at a later date, and 16 demographically matched community volunteers with no history of cancer (trial registration ACTRN12615000009516, available at http://www.ANZCTR.org.au/ACTRN12615000009516.aspx). The study was the first to include an adapted version of the Traumatic Brain Injury Self-Efficacy Scale to assess cognitive self-efficacy (CSE) in people who have experienced cancer. Results revealed participating in the intervention was associated with significantly faster performance on one objective cognitive task that measures processing speed and visual scanning. Significantly larger improvements for the intervention group were also found on measures of perceived cognitive impairments and CSE. There was some evidence to support the roles of CSE and illness perceptions as potential mechanisms of change for the intervention. Overall, the study provided additional evidence of feasibility and efficacy of group psychological intervention for targeting cancer-related cognitive decline.

A Systematic Review of the Efficacy of Community-based, Leisure/Social Activity Programmes for People with Traumatic Brain Injury

Background: Many people who have a severe traumatic brain injury (TBI) are not able to resume employment and consequently experience profound changes in their lifestyle. They have increased amounts of ’spare time’ yet often find it difficult to engage in meaningful activity. Leisure activities are one way in which meaningful activity can be increased.

Aims: This systematic review has two purposes: first, to identify and evaluate the efficacy of community-based interventions for leisure/social activity after TBI, and second to provide details on the types of intervention.

Method: Systematic searches were conducted of Medline, PsycINFO and PsycBITE to October 2014, as well as hand searches of two occupational therapy journals. Inclusion criteria were as follows: peer reviewed journal articles on adults with TBI who had participated in a trial evaluating a community-based intervention specifically targeting leisure/social activity. All research methodologies using primary studies that provided empirical, quantitative data were considered. Scientific quality of the studies was evaluated using the PEDro Scale for controlled trials and the Risk of Bias in N-of-1 Trials Scale for single-case designs.

Results: Two independent raters screened 196 abstracts, resulting in nine articles that met selection criteria. Data were then independently extracted by the raters. Four of the nine studies used a control condition in their research design (two randomised controlled trials, one controlled but non-randomised study, and one single-case experiment using a changing criterion design). Two of the studies conducted between-group analyses with significant treatment effects for mood and quality of life using active leisure programmes (Tai Chi Qigong and a combined programme of outdoor adventure experiences and goal setting respectively). Intervention programmes identified in the review were then grouped and described according to the approach or model used, including active leisure programmes, social peer mentoring, individual brokered leisure services and a therapeutic recreation model. Additional intervention models and approaches that did not result directly from the systematic review were also described because they provide information on the current approaches used in practice (Clubhouse model and leisure education programmes in the stroke population).

Conclusions: There is some evidence for the effectiveness of community-based interventions for leisure/social activity for people who have had a TBI to improve mood and quality of life. The conclusions of this review are that the interventions for this area need to be planned and specific, structured and goal-driven, intensive and conducted over a period of months.

The mental health sequelae of traumatic head injury in South Vietnamese ex-political detainees who survived torture

Little is known about the relationship between traumatic head injury (THI) and psychiatric morbidity in torture survivors. We examine the relationship between THI and depression, PTSD, post-concussive syndrome (PCS), disability and poor health status in Vietnamese ex-political detainees who survived incarceration in Vietnamese re-education camps. A community sample of ex-political detainees (n=337) and a non-THI, non-ex-detainee comparison group (n=82) were surveyed. Seventy-eight percent of the ex-political detainees had experienced THI; 90.6% of the ex-political detainees and 3.6% of the comparison group had experienced 7 or more trauma events. Depression and PTSD were greater in ex-detainees than in the comparison group (40.9% vs 23.2% and 13.4% vs 0%). Dose-effect relationships for THI and trauma/torture in the ex-political detainee group were significant. Logistic regression in the pooled sample of ex-detainees and the comparison group confirmed the independent impact of THI from trauma/torture on psychiatric morbidity (OR for PTSD=22.4; 95% CI: 3.0-165.8). These results demonstrate important effects of THI on depression and PTSD in Vietnamese ex-detainees who have survived torture.

Environmental enrichment and the sensory brain: the role of enrichment in remediating brain injury

The brain's life-long capacity for experience-dependent plasticity allows adaptation to new environments or to changes in the environment, and to changes in internal brain states such as occurs in brain damage. Since the initial discovery by Hebb (1947) that environmental enrichment (EE) was able to confer improvements in cognitive behavior, EE has been investigated as a powerful form of experience-dependent plasticity. Animal studies have shown that exposure to EE results in a number of molecular and morphological alterations, which are thought to underpin changes in neuronal function and ultimately, behavior. These consequences of EE make it ideally suited for investigation into its use as a potential therapy after neurological disorders, such as traumatic brain injury (TBI). In this review, we aim to first briefly discuss the effects of EE on behavior and neuronal function, followed by a review of the underlying molecular and structural changes that account for EE-dependent plasticity in the normal (uninjured) adult brain. We then extend this review to specifically address the role of EE in the treatment of experimental TBI, where we will discuss the demonstrated sensorimotor and cognitive benefits associated with exposure to EE, and their possible mechanisms. Finally, we will explore the use of EE-based rehabilitation in the treatment of human TBI patients, highlighting the remaining questions regarding the effects of EE.

Race and insurance disparities in discharge to rehabilitation for patients with traumatic brain injury

Post-acute inpatient rehabilitation services are associated with improved functional outcomes among persons with traumatic brain injury (TBI). We sought to investigate racial and insurance-based disparities in access to rehabilitation. Data from the Nationwide Inpatient Sample from 2005-2010 were analyzed using standard descriptive methods and multivariable logistic regression to assess race- and insurance-based differences in access to inpatient rehabilitation after TBI, controlling for patient- and hospital-level variables. Patients with moderate to severe TBI aged 18-64 years with complete data on race and insurance status discharged alive from inpatient care were eligible for study. Among 307,675 TBI survivors meeting study criteria and potentially eligible for discharge to rehabilitation, 66% were white, 12% black, 15% Hispanic, 2% Asian, and 5% other ethnic minorities. Most whites (70%), Asians (70%), blacks (59%), and many Hispanics (49%) had insurance. Compared with insured whites, insured blacks had reduced odds of discharge to rehabilitation (odds ratio [OR] 0.84; 95% confidence interval [CI] 0.75-0.95). Also, insured Hispanics (OR 0.52; 95% CI 0.44-0.60) and insured Asians (OR 0.54; 95% CI 0.39-0.73) were less likely to be discharged to rehabilitation than insured whites. Compared with insured whites, uninsured whites (OR 0.57; 95% CI 0.51-0.63), uninsured blacks (OR 0.33; 95% CI 0.26-0.42), uninsured Hispanics (OR 0.27; 95% CI 0.22-0.33), and uninsured Asians (OR 0.40; 95% CI 0.22-0.73) were less likely to be discharged to rehabilitation. Race and insurance are strong predictors of discharge to rehabilitation among adult TBI survivors in the United States. Efforts are needed to understand and eliminate disparities in access to rehabilitation after TBI.

Community integration outcomes after traumatic brain injury due to physical assault

BACKGROUND

Community integration is considered an ultimate goal for rehabilitation after traumatic brain injury (TBI).

PURPOSE

To determine (a) whether differences exist in rehabilitation outcomes between intentional and unintentional TBI populations and (b) whether TBI from assault is a predictor of community integration following inpatient rehabilitation.

METHOD

Retrospective cohort study using population-based data from Canadian hospital administration records, 2001 to 2006. Outcome measure was the Reintegration to Normal Living Index (RNLI).

FINDINGS

From a sample of 243 persons, 24 (9.9%) had sustained TBI from physical assault. Persons with TBI from physical assault reported significantly lower scores on two items on the RNLI's Daily Functioning subscale: "recreation" and "family role."

IMPLICATIONS

These findings suggest that targeted intervention in these specific areas could be beneficial, which are often primarily addressed by occupational therapists in both inpatient rehabilitation and community settings.

A preliminary investigation into psychosocial outcome and quality-of-life in adolescents following childhood traumatic brain injury

OBJECTIVE

This study investigated the long-term psychosocial outcome and quality-of-life (QoL) of 15-18 year olds, sustaining childhood traumatic brain injury (TBI) between birth and 5 years.

METHOD

Thirty-three participants (17 TBI parent-proxies, 16 control parent-proxies) were involved in the present study which compared parent-ratings for the TBI group and healthy controls on the Sydney Psychosocial Reintegration Scale-Child form (SPRS-C) and the Paediatric Quality of Life Inventory (PedsQL).

RESULTS

Despite comparable overall psychosocial reintegration scores, parents reported that their teens with TBI were more likely to experience poor QoL compared to controls. On further analysis, some aspects of psychosocial outcome appear to be compromised following childhood TBI.

CONCLUSIONS

Interventions targeting childhood TBI must consider QoL in addition to symptom reduction and be extended throughout adolescence. The limitations of the sample size are cause for concern; however, preliminary results do validate the need for future research efforts.

Integrating Interventions after Traumatic Brain Injury: A Synergistic Approach to Neurorehabilitation

Deficits in attention, processing speed and executive functioning are among the most commonly reported and functionally limiting cognitive impairments among individuals with TBI. Changes in mood can exacerbate cognitive deficits and reduce life quality. Contemporary hierarchical models of cognitive functioning suggest that attention/arousal processes underlie and support higher-order functions. Building on decades of clinical research, a synergistic, integrative approach to neurorehabilitation is described, which combines bottom-up and top-town cognitive interventions in addition to psychotherapeutic interventions for mood. This approach is intended to address directly impairments in both foundational (i.e., attention) and higher-order (i.e., executive functions) processes. Executive dysfunction is addressed in a top-down fashion through the application of a series of problem-solving and emotional regulation modules that teach and integrate strategies that can be generalised across situations with practice. Attention, arousal and information processing are necessary prerequisites of successful higher-order thinking, attention skills, and are addressed in a bottom-up fashion through intensive individualised attention and processing training tasks. Combining top-down and bottom-up approaches within a comprehensive day-treatment programme can effect a synergistic improvement of overall functioning.

A health and wellness intervention for those with moderate to severe traumatic brain injury: a randomized controlled trial

OBJECTIVES

To assess the efficacy of a standardized 12-week health and wellness group intervention for those with moderate to severe traumatic brain injury (TBI).

STUDY DESIGN

Randomized controlled trial.

PARTICIPANTS

Seventy-four individuals with moderate to severe TBI recruited from the outpatient program at a rehabilitation hospital, a Veterans Affairs Medical Center, and the community.

METHOD

Eligible participants were randomized to treatment (health and wellness therapy group) or wait-list control (treatment, n = 37; wait-list, n = 37). The primary outcome was the Health Promoting Lifestyle Profile-II.

RESULTS

The results of the mixed-model repeated-measures analysis indicated no differences between treatment and control groups engaging in activities to increase their health and well-being.

CONCLUSIONS

Findings did not support the efficacy of the intervention. Results may have been impacted by the wide variability of individualized health and wellness goals selected by group members, the structure and/or content of the group, and/or the outcome measures selected.

Traumatic brain injury and post-acute decline: what role does environmental enrichment play? A scoping review

Objectives: While a growing number of studies provide evidence of neural and cognitive decline in traumatic brain injury (TBI) survivors during the post-acute stages of injury, there is limited research as of yet on environmental factors that may influence this decline. The purposes of this paper, therefore, are to (1) examine evidence that environmental enrichment (EE) can influence long-term outcome following TBI, and (2) examine the nature of post-acute environments, whether they vary in degree of EE, and what impact these variations have on outcomes.

Methods: We conducted a scoping review to identify studies on EE in animals and humans, and post-discharge experiences that relate to barriers to recovery.

Results: One hundred and twenty-three articles that met inclusion criteria demonstrated the benefits of EE on brain and behavior in healthy and brain-injured animals and humans. Nineteen papers on post-discharge experiences revealed that variables such as insurance coverage, financial, and social support, home therapy, and transition from hospital to home, can have an impact on clinical outcomes.

Conclusion: There is evidence to suggest that lack of EE, whether from lack of resources or limited ability to engage in such environments, may play a role in post-acute cognitive and neural decline. Maximizing EE in the post-acute stages of TBI may improve long-term outcomes for the individual, their family and society.

Participation after multidisciplinary rehabilitation for moderate to severe traumatic brain injury in adults: a systematic review

OBJECTIVE

To determine the effectiveness and comparative effectiveness of multidisciplinary rehabilitation programs for moderate to severe traumatic brain injury (TBI) in improving participation-related outcomes in adults. This article presents results of select key questions from a recent Agency for Healthcare Quality and Research comparative effectiveness review.

DATA SOURCES

MEDLINE, Cochrane Central Register of Controlled Trials, and PsycINFO; hand searches of previous relevant reviews.

STUDY SELECTION

We included prospective controlled studies that evaluated the effectiveness or comparative effectiveness of multidisciplinary rehabilitation programs delivered to adults with moderate to severe TBI on their participation in life and community.

DATA EXTRACTION

We extracted data, assessed risk of bias, and evaluated strength of evidence. Participation was selected as our primary outcome and included measures of productivity (eg, return to employment or military service) and select scales measuring community integration. Only data from studies with a low or moderate risk of bias were synthesized.

DATA SYNTHESIS

Twelve studies met our inclusion criteria; of these, 8 were of low or moderate risk of bias (4 randomized controlled trials of 680 patients and 4 cohort studies of 190 patients, sample size 36-366). Heterogeneous populations, interventions, and outcomes precluded pooled analysis. Evidence was insufficient to draw conclusions about effectiveness. Evidence on comparative effectiveness often demonstrated that improvements were not different between groups; however, this evidence was low strength and may have limited generalizability.

CONCLUSIONS

Our review used a rigorous systematic review methodology and focused on participation after multidisciplinary rehabilitation programs for impairments from moderate to severe TBI. The available evidence did not demonstrate the superiority of one approach over another. This conclusion is consistent with previous reviews that examined other patient-centered outcomes. While these findings will have little clinical impact, they do point out the limited evidence available to assess effectiveness and comparative effectiveness while highlighting important issues to consider in future comparative effectiveness research on this topic.

Self-efficacy beliefs mediate the relationship between subjective cognitive functioning and physical and mental well-being after hematopoietic stem cell transplant

OBJECTIVE

Cognitive problems are commonly reported by hematopoietic stem cell transplant (HSCT) survivors and are associated with poorer physical and mental well-being. It was hypothesized that adverse effects of subjective cognitive impairment occur because cognitive difficulties reduce survivors' confidence that they can manage HSCT-related symptoms-that is, self-efficacy for symptom management.

METHODS

Hematopoietic stem cell transplant survivors (n = 245), 9 months to 3 years post-HSCT, completed measures of subjective cognitive functioning, self-efficacy for symptom management, and clinically important outcomes: depressed mood, anxiety, and quality of life. Mediation analyses using bootstrapping were conducted to investigate whether effects of subjective cognitive impairment on these outcomes were mediated by self-efficacy for cognitive, emotional (SE-Emotional), social (SE-Social), and physical (SE-Physical) symptom management.

RESULTS

Self-efficacy mediated relations between subjective cognitive impairment and depressed mood (total indirect effect = -0.0064 and 95% CI -0.0097 to -0.0036), anxiety (total indirect effect = -0.0045, CI -0.0072 to -0.0021), and quality of life (total indirect effect = 0.0952, CI 0.0901 to 0.2642). SE-Emotional was a unique mediator when the outcome was depressed mood and anxiety. SE-Social, SE-Physical, and SE-Emotional were specific mediators when outcome was quality of life.

CONCLUSIONS

Findings support the conclusion that subjective cognitive impairment reduces HSCT survivors' confidence in their ability to manage common post-HSCT symptoms, with implications for physical and mental well-being. Interventions that help enhance survivors' self-efficacy, particularly self-efficacy for the management of emotional symptoms, are likely to benefit HSCT survivors who report subjective cognitive impairment.

Relationships between kinesiotherapy methods used in rehabilitation and the course of lost function recovery following surgical treatment of cranio-cerebral trauma

INTRODUCTION AND AIM

This paper aims to outline the relationships between kinesiotherapy methods used in rehabilitation and the recovery of the patient's ability to perform activities of daily living (ADLs), improvement of functional condition, regression of pareses and improvement of conscious state following surgical treatment of traumatic subdural haematomas.

MATERIALS AND METHODS

The study was conducted on 84 patients treated surgically for traumatic subdural haematomas, divided into two groups. The key differentiating factor was the kinesiotherapy method used in rehabilitation. Patients were assessed using the International Scale of Muscle Weakness (ISMW), Barthel Index and modified Rankin Scale, while their conscious state was assessed using the Glasgow Coma Scale.

RESULTS

A significant improvement of the assessed features was observed in all patients. However, patients treated with proprioceptive neuromuscular facilitation (PNF) and elements of the Bobath concept regained lost function significantly faster than patients treated with traditional kinesiotherapy. No significant differences were observed in the course of improvement of conscious state between the two groups.

CONCLUSIONS

Treatment using functional elements may significantly accelerate the return of the ability to perform ADLs, improvement in functional condition and regression of pareses in comparison with traditional kinesiotherapy.

Community-Based Rehabilitation Following Brain Injury: Comparison of a Transitional Living Program and a Home-Based Program

Background and aims: Community-based rehabilitation programs for people with a brain injury are diverse. Comparative program evaluation is required to identify optimal type, intensity and duration of programs. The aim of this study was to compare the effectiveness of two community-based rehabilitation programs using a set of standardised outcome measures.

Methods: The study used a quantitative, multicentre, longitudinal design. Persons with severe traumatic brain injury (TBI,n= 39) and acquired brain impairment (n= 2) were recruited from two residential, transitional living programs (TLU;n= 21) and two home-based community rehabilitation programs (CR;n= 20). Participants were assessed via interview at program entry, 2 months and 6 months later using a broad range of standardised measures. The quantity and types of intervention provided to study participants were recorded. Results: No significant differences were identified between the TLU and CR groups at baseline or 6-month follow-up. Two significant group-by-time interactions were identified on the Community Integration Questionnaire (CIQ). First, the CR group had significantly greater changes in productivity (p= .003;d= 1.0) compared to the TLU group over time; by contrast, the TLU group showed significantly greater improvements in social integration (p= .007;d= .86). The TLU participants received up to five times more intervention than the CR participants. This finding is significant considering the similar levels of improvement in function made by both TLU and CR participants.

Conclusions: Both TLU and CR groups improved on a range of measures. The TLU group however, received significantly more face-to-face interventions. Further examination of the relationship between participant contextual factors, such as coping style and self-esteem, and impairments such as challenging behaviour and decreased self-awareness, of people attending TLU and CR programs is required.

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.

The adaptation process following acute onset disability: an interactive two-dimensional approach applied to acquired brain injury

Objective:

To describe a new model of the adaptation process following acquired brain injury, based on the patient’s goals, the patient’s abilities and the emotional response to the changes and the possible discrepancy between goals and achievements.

Background:

The process of adaptation after acquired brain injury is characterized by a continuous interaction of two processes: achieving maximal restoration of function and adjusting to the alterations and losses that occur in the various domains of functioning. Consequently, adaptation requires a balanced mix of restoration-oriented coping and loss-oriented coping. The commonly used framework to explain adaptation and coping, ‘The Theory of Stress and Coping’ of Lazarus and Folkman, does not capture this interactive duality.

Relevant theories:

This model additionally considers theories concerned with self-regulation of behaviour, self-awareness and self-efficacy, and with the setting and achievement of goals.

The two-dimensional model:

Our model proposes the simultaneous and continuous interaction of two pathways; goal pursuit (short term and long term) or revision as a result of success and failure in reducing distance between current state and expected future state and an affective response that is generated by the experienced goal-performance discrepancies. This affective response, in turn, influences the goals set. This two-dimensional representation covers the processes mentioned above: restoration of function and consideration of long-term limitations. We propose that adaptation centres on readjustment of long-term goals to new achievable but desired and important goals, and that this adjustment underlies re-establishing emotional stability. We discuss how the proposed model is related to actual rehabilitation practice.

Community integration following TBI: an examination of community integration measures within the ICF framework

PURPOSE

The objectives of the present study are (1) to examine whether the content of existing community integration measures used following traumatic brain injury (TBI) is represented in the International Classification of Functioning, Disability and Health (ICF) and (2) to determine if the ICF provides a reasonable framework within which such measurement tools may be compared.

METHOD

Five commonly-used assessment instruments were selected for inclusion. Independent raters mapped identified measurement concepts to the ICF using established linking rules.

RESULTS

One hundred and eighty-five concepts were identified from 85 items in five scales. Of these more than 75% could be linked to the ICF. The majority of linked concepts were assigned to 64 categories within the activities and participation component of the ICF; however, the focus of assessment within each instrument varied considerably.

CONCLUSION

Through a standardized process of item mapping to the ICF, one may examine operationalizations of community integration. This may help inform selection of a method of assessment appropriate to both the subject population and clinical or research purpose. However, this process allows comparison of only the objective content of measurement tools. Subjective evaluations may also be necessary to provide comprehensive assessment of community integration.

A prospective study to evaluate a residential community reintegration program for patients with chronic acquired brain injury

OBJECTIVE

To examine the effects of a residential community reintegration program on independent living, societal participation, emotional well-being, and quality of life in patients with chronic acquired brain injury and psychosocial problems hampering societal participation.

DESIGN

A prospective cohort study with a 3-month waiting list control period and 1-year follow up.

SETTING

A tertiary rehabilitation center for acquired brain injury.

PARTICIPANTS

Patients (N=70) with acquired brain injury (46 men; mean age, 25.1y; mean time post-onset, 5.2y; at follow up n=67).

INTERVENTION

A structured residential treatment program was offered directed at improving independence in domestic life, work, leisure time, and social interactions.

MAIN OUTCOME MEASURES

Community Integration Questionnaire (CIQ), Employability Rating Scale, living situation, school, work situation, work hours, Center for Epidemiological Studies Depression Scale, EuroQOL quality of life scale (2 scales), World Health Organization Quality of Life Scale Abbreviated (WHOQOL-BREF; 5 scales), and the Global Assessment of Functioning (GAF) scale.

RESULTS

There was an overall significant time effect for all outcome measures (multiple analysis of variance T(2)=26.16; F(36,557) 134.9; P=.000). There was no spontaneous recovery during the waiting-list period. The effect sizes for the CIQ, Employability Rating Scale, work hours, and GAF were large (partial η(2)=0.25, 0.35, 0.22, and 0.72, respectively). The effect sizes were moderate for 7 of the 8 emotional well-being and quality of life (sub)scales (partial η(2)=0.11-0.20). The WHOQOL-BREF environment subscale showed a small effect size (partial η(2)=0.05). Living independently rose from 25.4% before treatment to 72.4% after treatment and was still 65.7% at follow up.

CONCLUSIONS

This study shows that a residential community reintegration program leads to significant and relevant improvements of independent living, societal participation, emotional well-being, and quality of life in patients with chronic acquired brain injury and psychosocial problems hampering societal participation.

Evidence-based cognitive rehabilitation: updated review of the literature from 2003 through 2008

OBJECTIVE

To update our clinical recommendations for cognitive rehabilitation of people with traumatic brain injury (TBI) and stroke, based on a systematic review of the literature from 2003 through 2008.

DATA SOURCES

PubMed and Infotrieve literature searches were conducted using the terms attention, awareness, cognitive, communication, executive, language, memory, perception, problem solving, and/or reasoning combined with each of the following terms: rehabilitation, remediation, and training for articles published between 2003 and 2008. The task force initially identified citations for 198 published articles.

STUDY SELECTION

One hundred forty-one articles were selected for inclusion after our initial screening. Twenty-nine studies were excluded after further detailed review. Excluded articles included 4 descriptive studies without data, 6 nontreatment studies, 7 experimental manipulations, 6 reviews, 1 single case study not related to TBI or stroke, 2 articles where the intervention was provided to caretakers, 1 article redacted by the journal, and 2 reanalyses of prior publications. We fully reviewed and evaluated 112 studies.

DATA EXTRACTION

Articles were assigned to 1 of 6 categories reflecting the primary area of intervention: attention; vision and visuospatial functioning; language and communication skills; 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 112 studies, 14 were rated as class I, 5 as class Ia, 11 as class II, and 82 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 interventions for attention, memory, social communication skills, executive function, and for comprehensive-holistic neuropsychologic rehabilitation after TBI. Evidence supports visuospatial rehabilitation after right hemisphere stroke, and interventions for aphasia and apraxia after left hemisphere stroke. Together with our prior reviews, we have evaluated a total of 370 interventions, including 65 class I or Ia studies. There is now sufficient information to support evidence-based protocols and implement empirically-supported treatments for cognitive disability after TBI and stroke.

Outcome measures for traumatic brain injury

Traumatic brain injury (TBI) is a major public health problem resulting in death and disabilities of young and productive people. Though the mortality of TBI has decreased substantially in recent years the disability due to TBI has not appreciably reduced. Various outcome scales have been proposed and used to assess disability after TBI. A few, commonly used are Glasgow Outcome Scale (GOS) with or without extended scores, Disability Rating Scale (DRS), Functional Independence Measure (FIM), Community Integration Questionnaire (CIQ), and the Functional Status Examination (FSE). These scales assess disability resulting from physical and cognitive impairments. For patients with good physical recovery a cognitive and neuropsychological outcome measure is required. Such measures include Neurobehavioural Function Inventory and specific neuropsychological tests like Rey Complex Figure for visuoconstruction and memory, Controlled Oral Word Association for verbal fluency, Symbol Digit Modalities (verbal) for sustained attention and Grooved Pegboard for fine motor dexterity. A more holistic and complete outcome measure is Quality of Life (QOL). Disease specific QOL measure for TBI, Quality of Life after Brain Injury (QOLIBRI) has also been recently proposed. The problems with outcome measures include poor operational definitions, lack of sensitivity or low ceiling effects, inability to evaluate patients who cannot report, lack of integration of morbidity and mortality categories, and limited domains of functioning assessed. GOSE-E satisfies most of the criteria of good outcome scale and in combination with neuropsychological tests is a near complete instrument for assessment of outcome after TBI.

Outcomes of post-acute rehabilitation for persons with brain injury

OBJECTIVES

To examine the impact of multifaceted rehabilitation services on functional outcomes after traumatic brain injury (TBI) for individuals with significant physical and cognitive difficulties, as well as those with added behavioural complications.

DESIGN

Cohort, non-randomized, intervention study with a pre-test-post-test, follow-up design.

SETTING

Community integrated post-acute rehabilitation centre.

PARTICIPANTS

Individuals with primarily severe TBI receiving post-acute neurorehabilitation services (NR, n = 129) as well as similarly impaired individuals with additional antagonistic/disruptive behaviours receiving neurobehavioural services (NB, n = 76).

INTERVENTIONS

Multi-faceted behavioural and cognitive therapy methods delivered individually and in groups.

MAIN OUTCOME MEASURE

The Functional Area Outcome Menu (FAOM), a behaviourally anchored 5-step scale rated by rehabilitation teams at three time periods.

CONCLUSIONS

The rehabilitation treatment model achieved significant functional gains of approximately 1.5 levels for neuropsychologically-impaired adults with and without associated behavioural and substance problems.

Cognitive correlates with functional outcomes after anoxic brain injury: a case-controlled comparison with traumatic brain injury

OBJECTIVES

To assess the effectiveness of inpatient rehabilitation in adults who have sustained an anoxic brain injury (AnBI). Secondly, to identify areas of cognition that predict functional outcomes at discharge.

DESIGN

Retrospective, matched case-controlled study.

METHODS

Ten patients with moderate-to-severe AnBI and 10 patients with traumatic brain injury (TBI), treated in an inpatient neurorehabilitation programme, were matched on age, acute care length of stay and admission Functional Independence Measure (FIM). Functional outcome was assessed using the FIM and Disability Rating Scale (DRS).

RESULTS

Patients with AnBI performed worse on all measures of functional outcome relative to patients with TBI. Patients with AnBI achieved significantly lower FIM motor and cognitive gain compared with patients with TBI (11.5, SD 13.6 vs. 31.0, SD 19.7 and 2.4, SD 3.9 vs. 7.5, SD 4.2, respectively (p < 0.02)). DRS data showed similar trends of functional improvement between the groups. Several neuropsychometric tests correlated with functional outcome (p < 0.01).

CONCLUSIONS

Patients with AnBI had worse functional outcomes following rehabilitation than patients with TBI, confirming the results of previous reports. Poor cognitive function predicted poor functional outcomes on the FIM and somewhat on the DRS. Research is needed to assess why these differences occur and to improve or develop new effective rehabilitation treatments for AnBI.

Regional brain morphometry predicts memory rehabilitation outcome after traumatic brain injury

Cognitive deficits following traumatic brain injury (TBI) commonly include difficulties with memory, attention, and executive dysfunction. These deficits are amenable to cognitive rehabilitation, but optimally selecting rehabilitation programs for individual patients remains a challenge. Recent methods for quantifying regional brain morphometry allow for automated quantification of tissue volumes in numerous distinct brain structures. We hypothesized that such quantitative structural information could help identify individuals more or less likely to benefit from memory rehabilitation. Fifty individuals with TBI of all severities who reported having memory difficulties first underwent structural MRI scanning. They then participated in a 12 session memory rehabilitation program emphasizing internal memory strategies (I-MEMS). Primary outcome measures (HVLT, RBMT) were collected at the time of the MRI scan, immediately following therapy, and again at 1-month post-therapy. Regional brain volumes were used to predict outcome, adjusting for standard predictors (e.g., injury severity, age, education, pretest scores). We identified several brain regions that provided significant predictions of rehabilitation outcome, including the volume of the hippocampus, the lateral prefrontal cortex, the thalamus, and several subregions of the cingulate cortex. The prediction range of regional brain volumes were in some cases nearly equal in magnitude to prediction ranges provided by pretest scores on the outcome variable. We conclude that specific cerebral networks including these regions may contribute to learning during I-MEMS rehabilitation, and suggest that morphometric measures may provide substantial predictive value for rehabilitation outcome in other cognitive interventions as well.

Measuring perceived difficulty in post-acute brain injury rehabilitation: The Sister Kenny Symptom Management Scale

PRIMARY OBJECTIVE

Patients' perceptions of difficulty managing symptoms contribute to disability after brain injury. This study introduces the Sister Kenny Symptom Management Scale (KSMS) and reports on its factor structure, reliability, validity and clinical value.

METHOD

Archived data from (overlapping) samples of patients with brain injuries of mixed aetiologies, seen at an outpatient clinic over 16 years were used in development and validation studies of the KSMS. Comparison measures included the Profile of Mood States (POMS), neuropsychological test scores and employment.

RESULTS

Factor analysis of 34 items (n = 328) identified five sub-scales with satisfactory internal consistency and test-re-test stability representing difficulty with executive functions, language, recent memory, aggressive behaviour and physical symptoms. A pattern of correlations (n = 336) with Profile of Mood States (POMS) sub-scales of similar and different content supported the concurrent validity of KSMS sub-scales. Only the Memory sub-scale correlated with its test index. The Language score and test index approached significance. The Executive sub-scale did not. Hierarchical regression analysis (n = 102) that included ratings of mood and symptom management showed that employment after discharge was only predicted by post-treatment ratings of difficulty with cognitive functions.

CONCLUSION

Self-assessments of difficulty managing symptoms can be reliably assessed and may contribute to understanding patients' disability, treatment response and future prospects.

Effectiveness of Rehabilitation in Enhancing Community Integration After Acute Traumatic Brain Injury: A Systematic Review

OBJECTIVE. We assessed evidence for post–acute traumatic brain injury (TBI) rehabilitation interventions used to enhance community integration (CI) relevant to occupational therapy.

METHOD. We conducted a systematic review of intervention studies on TBI rehabilitation from 1990 to 2007.

RESULTS. We analyzed and summarized 10 studies that met the inclusion criteria. Of 10 studies, 7 found that post–acute TBI rehabilitation benefits CI; all effective studies involved occupational therapy or involved interventions occupational therapists can do.

CONCLUSION. Many CI programs show positive results and should be studied more rigorously. Such promising programs should also be considered when decisions about post–acute TBI rehabilitation services for clients are being made. To further establish that post–acute TBI rehabilitation interventions improve CI, future studies should include intervention strategies based on injury severity, a control group, and longer term follow-up. The role of occupational therapy in these effective programs should be further explored.

What is community integration anyway?: defining meaning following traumatic brain injury

Full community integration, or participation in society, is the ultimate goal of rehabilitation and of research conducted in the field of rehabilitation for persons with traumatic brain injury (TBI). Community integration has been traditionally defined by 3 main areas: employment or other productive activity, independent living, and social activity. However, these have not always received equal weighting and attention in clinical or research efforts. Significant gaps remain in our understanding of factors that impact community integration and in our ability to intervene to improve participation for persons with TBI. This article describes 3 main challenges for researchers and rehabilitation professionals. First, a comprehensive meaning of community integration is needed, which includes the viewpoints and preferences of persons with TBI. Second, cultural competence in measurement and intervention is needed. Third, a thorough assessment of environmental factors impacting participation is needed and should be incorporated into research and treatment planning.
