Improved self-awareness and coping strategies for patients with acquired brain injury--a group therapy programme

A systematic literature review of the impact of impaired self-awareness on the process of rehabilitation in acquired brain injury

BACKGROUND

Impaired self-awareness (ISA) is common in individuals with an acquired brain injury (ABI) and can lead to reduced awareness of one's difficulties. Previous reviews have found that ISA impacts on functional outcomes in rehabilitation. However, to date there has not been a systematic literature review which examines how ISA impacts on the process of rehabilitation in ABI populations.

METHOD

A literature search was conducted using several databases in May 2024, including Academic Search Premier, CINAHL, MEDLINE, APA PsycARTICLES and APA PsycINFO. Seventeen articles were selected for the review and were analyzed using Narrative Synthesis.

RESULTS

Four themes arose from the findings, including goal setting, treatment adherence, engagement and willingness to change and time spent in hospital. ISA was found to impact on the value adult ABI participants placed in rehabilitation, which decreased treatment compliance, motivation, and engagement. ISA also impacted on goal setting and behavior and resulted in a longer length of time spent in hospital.

CONCLUSION

This review emphasizes the impact of ISA on various aspects/processes of rehabilitation in ABI and provides considerations of how clinicians might adapt interventions to manage these difficulties.

Coping Strategies in Patients with Acquired Brain Injury: A Scoping Review

In recent years, there has been marked interest in looking at the psychological consequences of medical conditions, such as traumatic or acquired brain injuries. Coping strategies are essential for clinical recovery and for dealing with the stressful events that a clinical condition brings with it. The purpose of this review is to analyze studies that explore how coping strategies influence psychological changes in patients with acquired brain injury. Studies were identified from research in the PubMed, Scopus, and Embase databases. According to our findings, patients with ABI utilize different coping strategies based on the circumstances and factors such as the diagnosis severity, their age, time lived with the pathology, and personal characteristics, which have an influence on quality of life and rehabilitation. This review demonstrated that coping strategies have an impact on different aspects of the clinical and personal lives of patients with ABI. The rehabilitation process must consider the influence of these mechanisms on dealing with situations, as they can change cognitive and emotional perceptions of patients' experience with the disease, as well as laying the foundations for functional or dysfunction in terms of the propensity of a person for the path of psychological and physical recovery.

"We can all relate": patient experience of an emotion-oriented group intervention after Acquired Brain Injury

Introduction

Group interventions are carried out routinely across neuropsychological rehabilitation services, to improve understanding of brain injury and aspects of impairment. Treatment provided in a group modality can bring additional perceived benefits, such as co-operative learning. However, there are very few studies which explore patient perceptions and experiences of such interventions. In the present study we investigated the experience of attending a group-based educational intervention for the consequences of acquired brain injury (ABI), which had a strong focus on emotion and emotion regulation.

Methods

Using qualitative semi-structured interviews (approximately 20 minutes), the study explores the lived experience of participating in the seven-session programme, the better to identify the perceived efficacy, salience and value of individual elements. Twenty participants with ABI took part in individual interviews, after completion of the group programme (the Brain Injury Solutions and Emotions Programme, BISEP). The study adopted a descriptive phenomenological philosophy, which focuses on lived experience to explore a phenomenon (i.e. the experience of BISEP). As regards methods, the study employed thematic analysis to cluster experiences into themes of meaning.

Results

Five themes were identified: (1) 'Long term consequences and psychological needs', which related to the persistent nature of direct consequences of injury and adjustment, and how these result in a need for interventions such as BISEP. (2) 'Positive experiences of participating in the programme', referred to participants' overall experience of the programme and valued elements within it. The remaining themes referred to the programme as (3) a social milieu; (4) a place to learn; and (5) a place to promote positive emotional experiences.

Discussion

Similar to previous studies, many people reported high acceptability and perceived value of the group programme, and its role in facilitating adjustment and understanding of injury. Of particular importance was the opportunity to socialise with people who "can all relate", in line with a growing emphasis on social rehabilitation. The findings especially highlight the relevance of emotion-focused group programmes for ABI, promoting emotion regulation, and practical tools that are delivered optimistically. Further implications for practice and future research include to focus on long term rehabilitation, a social milieu, and strategies to support adjustment.

Socratic guided feedback therapy after acquired brain injury: A multicenter randomized controlled trial to evaluate effects on self-awareness

Impaired self-awareness after acquired brain injury (ABI) challenges neuropsychological rehabilitation. The current study aimed to compare the effects of Socratic Guided Feedback therapy to usual care in a multicenter randomized controlled trial with 64 participants with reduced self-awareness after ABI. The objectives were to study the effects on (1) self-awareness and (2) motivation for and participation in therapy, mood, quality of life, and social participation. Patients were recruited from rehabilitation centres in The Netherlands and Belgium. They were 50.8 (±16) years old and 2.7 months (±1.8) post-injury at baseline. Session duration ranged from 20-60 minutes and the number of sessions ranged from 1 to 162 sessions. Self-awareness increased over time in both groups. Between 9 and 12 months after baseline measurement, self-awareness (Patient Competency Rating Scale discrepancy score between patient and significant other) improved in the experimental group and deteriorated in care as usual. No significant differences were found on secondary outcome measures. In conclusion, Socratic Guided Feedback therapy is as effective as care as usual but provides a structure for therapists. We recommend further investigation of the added value of Socratic Guided Feedback therapy in later follow-up measurements, group therapy settings, and on other outcome domains such as caregiver burden.

Online awareness: a concept analysis and review of assessment approaches for adults with neurological conditions

PURPOSE

Self-awareness is a multifaceted phenomenon that comprises two main concepts: general awareness and online awareness. The latter is an emerging concept that requires further consensus on its definition. The aim of this paper is to define the key components of online awareness and identify approaches for measuring this concept for adults with neurological conditions.

MATERIALS AND METHODS

Concept analysis using Rodgers' evolutionary method was used to systematically review and summarise relevant literature. Papers were included if they provided a definition of online awareness or method for assessing online awareness for an adult neurological population.

RESULTS

Fifty-six papers were included in this review, with 21 online awareness assessment approaches identified. Online awareness was described to occur within the context of task performance, with the definition framework comprising four main aspects: 1/appraisal; 2/anticipation and prediction; 3/monitoring; and 4/self-evaluation. Self-regulation is a related concept that is considered to sit outside the conceptual boundaries of online awareness.

CONCLUSIONS

The findings of this analysis highlight the complexity of online awareness and its importance in rehabilitation. Psychometrically robust measures of online awareness that are inclusive of the essential elements of this concept are needed to advance practice in this area.

Description of an interdisciplinary, holistic cognitive rehabilitation program for adults with mild to moderate cognitive impairment after acquired brain injury

PURPOSE

Cognitive rehabilitation research has progressed slowly, in part due to incomplete reporting of intervention content and delivery and the difficulties this produces for discerning program effectiveness. This knowledge gap can be reduced by providing detailed intervention descriptions. We document the content/ingredients and therapeutic targets of a cognitive rehabilitation program for adults with mild-to-moderate cognitive impairment.

METHODS

The documentation process used a method of participatory/collaborative research. Discussions with the clinical team identified session content/ingredients and therapeutic targets, which were then described using Body Functions, and Activities & Participation domains from the International Classification of Function, Disability and Health (ICF). Domains most frequently targeted by each clinician were identified as Primary Targets.

RESULTS

Each clinician produced a detailed description of session content, implementation, and ICF-coded therapeutic targets. This revealed that the whole program targets 29 ICF domains, seven of which were identified as Primary Targets: Higher-level Cognitive; Attention; Memory; Emotional; Global Psychosocial, Temperament and Personality, and Conversation.

CONCLUSIONS

Documentation of treatment targets enabled identification of appropriate outcome measures which are now being used to investigate program efficacy. This step-by-step explanation of the documentation process could serve as a guide for other teams wanting to document their rehabilitation interventions and/or establish similar programs.IMPLICATIONS FOR REHABILITATIONIncomplete reporting of intervention content and delivery contributes to difficulties in discerning the effectiveness of complex rehabilitation programs.Current recommendations for rehabilitation intervention reporting suggest that these difficulties can be partially overcome by providing detailed descriptions of intervention content/ingredients and treatment targets.Human and physical resources differ widely from one clinical setting to another and the existence of clear program descriptions can guide clinicians who wish to create similar programs.Detailed descriptions of rehabilitation interventions are necessary to accurately measure patient outcomes and generate testable hypotheses about proposed mechanisms of action.Program descriptions are needed for the development of treatment theories and the advancement of evidence-based practice in rehabilitation.

Building the bond: Predictors of the alliance in neurorehabilitation

BACKGROUND

Neurorehabilitation services are often delivered through group psycho-education programmes. However, little is known about the therapeutic process at work during such sessions. The present study is the first to gain insight into the therapeutic alliance, during a seven-session group programme. In addition, cognitive, emotional, and demographic predictors of the alliance, and participants' feelings towards their group members, were investigated, together with predictors of patient engagement.

METHODS

Forty-five participants with an acquired brain injury completed a series of questionnaires, and neuropsychological assessment, following group psycho-education. The group facilitator completed a parallel therapeutic alliance questionnaire, and rated participants' engagement.

RESULTS

Results demonstrated that a strong alliance can be formed in seven group sessions. Notably, no demographic or cognitive factors appear to pose a barrier to developing a therapeutic alliance, nor to group attraction.

CONCLUSION

High levels of depression, however, may be a challenge, and clinicians may need to tailor their clinical skills to ensure a good therapeutic relationship with such patients. To promote engagement, clinicians may also need to provide additional support to patients with lower levels of education, working memory, and episodic memory impairment.

A retrospective study on the acceptability, feasibility, and effectiveness of LoveYourBrain Yoga for people with traumatic brain injury and caregivers

PURPOSE

To conduct a mixed methods, pre-post, retrospective study on the feasibility, acceptability, and effectiveness of the LoveYourBrain Yoga program.

MATERIALS AND METHODS

People were eligible if they were a traumatic brain injury survivor or caregiver, age 15-70, ambulatory, and capable of gentle exercise and group discussion. We analyzed attendance, satisfaction, and mean differences in scores on Quality of Life After Brain Injury Overall scale (QOLIBRI-OS) and four TBI-QOL/Neuro-QOL scales. Content analysis explored perceptions of benefits and areas of improvement.

RESULTS

1563 people (82.0%) participated ≥1 class in 156 programs across 18 states and 3 Canadian provinces. Mean satisfaction was 9.3 out of 10 (SD 1.0). Mixed effects linear regression found significant improvements in QOLIBRI-OS (B 9.70, 95% CI: 8.51, 10.90), Resilience (B 1.30, 95% CI: 0.60, 2.06), Positive Affect and Well-being (B 1.49, 95% CI: 1.14, 1.84), and Cognition (B 1.48, 95% CI: 0.78, 2.18) among traumatic brain injury survivors (n = 705). No improvement was found in Emotional and Behavioral Dysregulation, however, content analysis revealed better ability to regulate anxiety, anger, stress, and impulsivity. Caregivers perceived improvements in physical and psychological health.

CONCLUSIONS

LoveYourBrain Yoga is feasible and acceptable and may be an effective mode of community-based rehabilitation.IMPLICATIONS FOR REHABILITATIONPeople with traumatic brain injury and their caregivers often experience poor quality of life and difficulty accessing community-based rehabilitation services.Yoga is a holistic, mind-body therapy with many benefits to quality of life, yet is largely inaccessible to people affected by traumatic brain injury in community settings.Participants in LoveYourBrain Yoga, a six-session, community-based yoga with psychoeducation program in 18 states and 3 Canadian provinces, experienced significant improvements in quality of life, resilience, cognition, and positive affect.LoveYourBrain Yoga is feasible and acceptable when implemented on a large scale and may be an effective mode of, or adjunct to, community-based rehabilitation.

Improving Self-awareness After Acquired Brain Injury Leads to Enhancements in Patients’ Daily Living Functionality

Objective:

To explore whether the improvement in self-awareness induced by a structured intervention programme in patients suffering a brain injury is associated with an enhancement in their functional outcomes.

Method:

This study uses a pre- and post-test control group design with a sample of 56 patients with acquired brain injury randomly assigned to an experimental and a control group. Pre- and post-intervention measurements were self-awareness (using a previously developed scale) and functional outcome (using the Lawton Instrumental Activities of Daily Living Scale).

Results:

Patients who received the intervention programme showed a greater improvement in their self-awareness level and functional outcome than patients in the control group. Additionally, the correlation analyses between improvements at both measures showed a relation between improvement in self-awareness and improvement in functional outcome, especially when the pre-treatment self-awareness level was considered.

Conclusions:

Implementing an intervention programme in self-awareness, in the context of a global rehabilitation process of patients with acquired brain injury, is useful for improving their self-awareness level and the functionality in their daily activities.

Patient perceptions of participation in group-based rehabilitation in an inpatient brain injury rehabilitation setting

OBJECTIVES

The use of groups is common in healthcare. There is a paucity of research which captures patient experiences of group participation. The aims of this study were to explore the perceptions and experiences of people with traumatic brain injury (TBI) about their participation in inpatient occupational therapy rehabilitation groups.

METHOD

A phenomenological approach guided the study. Patients with a TBI who were participating in an inpatient occupational therapy group program were recruited. Data were collected through semi-structured interviews and analysed using content analysis.

RESULTS

Fifteen participants consented to the study. Three themes emerged from the data; 1) feeling normal, comfortable and connected; 2) learning by doing, seeing and sharing and; 3) practicalities of groups. Participants highlighted that groups facilitated opportunities to practice skills and prepared them for the real world. Opportunities for interaction and support were also emphasised as positive by participants.

CONCLUSION

Perceptions of patients about participation in groups were generally positive, and as such a consumer-focused approach to healthcare would support the use of occupational therapy groups in TBI rehabilitation.

PRACTICE IMPLICATIONS

Recommendations from the perspectives of patients include consideration of the selection of group participants, and meeting individual needs and goals within a group setting.

Interventions to enhance coping after traumatic brain injury: A systematic review

Background/Aims:

The aim of this study was to identify effective psychosocial interventions to enhance coping in people who have experienced a traumatic brain injury, in order to inform clinical practice and articulate future research directions.

Methods:

Five electronic databases (CINAHL, Medline, EMBASE, PsycINFO, and Cochrane Library) were searched. Titles and abstracts were independently screened by two of the authors and selected for inclusion. The full text of all potentially relevant studies were retrieved and assessed for eligibility, reporting and methodological quality, and risk of bias.

Findings:

Eight included studies were very heterogeneous in terms of study design, type of intervention, the population studied and instruments used to evaluate coping. All studies were judged to have a moderately high risk of bias. Six studies used cognitive behavioural therapy-based interventions. Two interventions (a peer-mentoring programme and cognitive behavioural therapy combined with motivational interviewing) showed significant treatment effects on maladaptive coping. Two cognitive behavioural therapy-based group programmes improved adaptive coping, but increases were either not sustained over time or no longer significant when compared to an active control.

Conclusions:

There is insufficient evidence to support practice recommendations strongly. Targeting specific subgroups of people who have experienced traumatic brain injury might allow the development of more effective coping interventions. Further, a more unified concept of coping in traumatic brain injury needs to be articulated allowing larger scale evaluations.

Rehabilitation of emergent awareness of errors post traumatic brain injury: A pilot intervention

Impaired awareness of errors is common following traumatic brain injury (TBI) and can be a barrier to successful rehabilitation. The objective of this study was to develop and evaluate a computer-based intervention programme aimed at improving error awareness in individuals with TBI. A further aim was to explore its effects on metacognitive awareness and variability of performance. Participants were 11 individuals with TBI and impaired error awareness who performed a sustained attention task twice-weekly for four weeks. The intervention consisted of audio-visual feedback-on-errors during the sustained attention task. Six participants received audio-visual feedback-on-error, five did not receive feedback. Emergent and metacognitive awareness were measured pre- and post-intervention. Between-groups comparisons of emergent awareness from pre- to post-intervention showed that audio-visual feedback-on-error improved emergent awareness compared to no feedback-on-error. Some changes in metacognitive awareness of executive behaviours as a result of feedback were observed. Audio-visual feedback-on-error improved emergent awareness in individuals with TBI following a four-week/eight-session intervention. This improvement was not observed in the no-feedback group. This pilot intervention is not a stand-alone treatment but it has potential to be usefully incorporated into cognitive or clinical rehabilitation programmes to improve emergent awareness.

Self-awareness rehabilitation after Traumatic Brain Injury: A pilot study to compare two group therapies

BACKGROUND AND PURPOSE

Deficits of self-awareness (SA) are very common after severe acquired brain injury (sABI), especially in traumatic brain injury (TBI), playing an important role in the efficacy of the rehabilitation process. This pilot study provides information regarding two structured group therapies for disorders of SA.

METHODS

Nine patients with severe TBI were consecutively recruited and randomly assigned to one SA group therapy programme, according either to the model proposed by Ben-Yishay & Lakin (1989) (B&L Group), or by Sohlberg & Mateer (1989) (S&M Group). Neuropsychological tests and self-awareness questionnaires were administered before and after a 10 weeks group therapy.

RESULTS

Results showed that both SA and neuropsychological functioning significantly improved in both groups.

CONCLUSION

It is important to investigate and treat self-awareness, also to improve the outcome of neuropsychological disorders. The two group therapies proposed seem to be specific for impulsivity and emotional dyscontrol and for cognitive disorders.

Effectiveness of Interventions to Address Cognitive Impairments and Improve Occupational Performance After Traumatic Brain Injury: A Systematic Review

OBJECTIVE. To determine the effectiveness of interventions addressing cognitive impairments to improve occupational performance for people with traumatic brain injury.

METHOD. A total of 37 studies met inclusion criteria: 9 Level I systematic reviews, 14 Level I studies, 5 Level II studies, and 9 Level III studies.

RESULTS. Strong evidence supports use of direct attention training, dual-task training, and strategy training to optimize executive functioning, encoding, and use of memory compensations, including assistive technology. However, in most studies, occupational performance was a secondary outcome, if it was evaluated at all.

CONCLUSION. Although evidence supports many intervention approaches used by occupational therapy practitioners to address cognitive impairments of adults with traumatic brain injury, more studies are needed in which occupational performance is the primary outcome of cognitive intervention.

Metacognitive function poststroke: a review of definition and assessment

Metacognition is the conscious knowledge individuals have about their own cognitive capacities and the regulation of these activities through self-monitoring. The aim of this review was to identify the definitions and assessment tools used to examine metacognition in relation to stroke studies. A computer database search was conducted using MEDLINE, CINAHL, PsycINFO, Cochrane Reviews, Scopus and Web of Science. A total of 1412 publications were retrieved from the initial database search. Following the removal of unrelated articles, 34 articles remained eligible. 5 studies examined metacognition in relation to cognitive and/or emotional functioning, 4 examined the concept in relation to memory, while others investigated its relationship to driving, employment or restrictions in daily living. 12 studies examined metacognitive function exclusively in stroke. Only 1 study examined metacognition in the acute phase of stroke. 7 studies adhered to the standard definition of metacognition in line with the neuropsychological literature. The main assessment tools utilised included the Self-Regulation and Skills Interview (SRSI), the Self-Awareness of Deficits Interview (SADI), the Awareness Questionnaire (AQ) and the Patient Competency Rating Scale (PCRS). Assessment of metacognition has tended to focus on traumatic and other acquired brain injury in comparison to stroke. The majority of the studies that examined metacognition in stroke did not assess patients in the acute phase. The heterogeneity of assessment tools was in keeping with the variation in the definition of metacognition. The emergence of a standard metacognitive assessment tool may have important implications for future rehabilitative programmes.

Non pharmacological treatments for psychological and behavioural disorders following traumatic brain injury (TBI). A systematic literature review and expert opinion leading to recommendations

INTRODUCTION

The non pharmacological approach is an important issue in the treatment of psychological and behavioural disorders in traumatic brain injury (TBI) patients. It remains nevertheless insufficiently known and defined. The objective of this work was to develop precise recommendations for caregivers and relatives.

METHOD

The elaboration of these guidelines followed the procedure validated by the French health authority for good practice recommendations, close to the Prisma statement, involving a systematic, critical review of the literature and the expert opinions of the French Society of Physical Medicine and Rehabilitation (SOFMER) group.

RESULTS

458 articles were identified, among which 98 were selected for their relevance to the theme of the research. None of the studies reached the highest level of evidence. Fifteen controlled studies reached a relatively high level of evidence (level 2); other studies were case series or expert opinions, and other articles again were reviews of the literature and theoretical points of view. The holistic approach structured into programmes, cognitive-behavioural therapy, and family and systemic therapy, despite the low levels of proof, are recommended in first intention at all stages in the evolution of TBI. Relational and adaptive approaches, rehabilitation and vocational approaches, and psychoanalytical therapies may be useful, provided that therapists are familiar with and trained in traumatic brain injury.

CONCLUSION

Despite the small number of publications and a low level of proof, a number of recommendations for the non-pharmacological approach to psychological and behavioural disorders in TBI is proposed by the consensus conference of experts. Scientific research in this domain is needed to confirm and complete these first recommendations.

Cognitive Rehabilitation After Traumatic Brain Injury: A Reference for Occupational Therapists

Nearly 1.7 million Americans sustain a traumatic brain injury (TBI) each year. These injuries can result in physical, emotional, and cognitive consequences. While many individuals receive cognitive rehabilitation from occupational therapists (OTs), the interdisciplinary nature of TBI research makes it difficult to remain up-to-date on relevant findings. We conducted a literature review to identify and summarize interdisciplinary evidence-based practice targeting cognitive rehabilitation for civilian adults with TBI. Our review summarizes TBI background, and our cognitive remediation section focuses on the findings from 37 recent (since 2006) empirical articles directly related to cognitive rehabilitation for individuals (i.e., excluding special populations such as veterans or athletes). This manuscript is offered as a tool for OTs engaged in cognitive rehabilitation and as a means to highlight arenas where more empirical, interdisciplinary research is needed.

Videogame-based group therapy to improve self-awareness and social skills after traumatic brain injury

Background

This study determines the feasibility of different approaches to integrative videogame-based group therapy for improving self-awareness, social skills, and behaviors among traumatic brain injury (TBI) victims and retrieves participant feedback.

Methods

Forty-two adult TBI survivors were included in a longitudinal study with a pre- and post-assessments. The experimental intervention involved weekly one-hour sessions conducted over six months. Participants were assessed using the Self-Awareness Deficits Interview (SADI), Patient Competency Rating Scale (PCRS), the Social Skills Scale (SSS), the Frontal Systems Behavior Scale (FrSBe), the System Usability Scale (SUS). Pearson's chi-squared test (χ²) was applied to determine the percentage of participants who had changed their clinical classification in these tests. Feedback of the intervention was collected through the Intrinsic Motivation Inventory (IMI).

Results

SADI results showed an improvement in participant perceptions of deficits (χ² = 5.25, p < 0.05), of their implications (χ² = 4.71, p < 0.05), and of long-term planning (χ² = 7.86, p < 0.01). PCRS results confirm these findings (χ² = 5.79, p < 0.05). SSS results were also positive with respect to social skills outcomes (χ² = 17.52, p < 0.01), and FrSBe results showed behavioral improvements (χ² = 34.12, p < 0.01). Participants deemed the system accessible (80.43 ± 8.01 out of 100) and regarded the intervention as interesting and useful (5.74 ± 0.69 out of 7).

Conclusions

Integrative videogame-based group therapy can improve self-awareness, social skills, and behaviors among individuals with chronic TBI, and the approach is considered effective and motivating.

The impact of self-awareness and depression on subjective reports of memory, quality-of-life and satisfaction with life following TBI

OBJECTIVE

To determine the relationship between self-awareness and depressive symptomatology with self-reports of memory, Quality-of-Life (QoL) and satisfaction with life in individuals with traumatic brain injury (TBI).

METHODS

Cross-sectional survey of 30 community dwelling adults, who sustained a TBI at least 1 year prior to study enrolment. Participants completed questionnaires to assess the constructs of depression, self-awareness, QoL, satisfaction with life and memory.

RESULTS

Symptoms of depression were significantly associated with self-reports of poor memory abilities, lower QoL and lower satisfaction with life. Additionally, higher levels of self-awareness were associated with lower ratings of QoL and reduced memory abilities and better strategy use regarding memory. However, when examining the contribution of each construct individually, depressive symptomatology, and not self-awareness, was significantly associated with subjective self-reports of memory, QoL and satisfaction with life.

CONCLUSIONS

This pattern of relationships illustrates that, when a person has a low level of depressive symptoms, his/her reports of QoL, memory and satisfaction with life will be more positive; however, he/she will demonstrate more difficulty with self-awareness. Thus, psychological aspects of recovery must, therefore, be taken into account when using self-reported measures in the evaluation of persons who have sustained TBI.

Cognitive rehabilitation for executive dysfunction in adults with stroke or other adult non-progressive acquired brain damage

BACKGROUND

Executive functions are the controlling mechanisms of the brain and include the processes of planning, initiation, organisation, inhibition, problem solving, self monitoring and error correction. They are essential for goal-oriented behaviour and responding to new and novel situations. A high number of people with acquired brain injury, including around 75% of stroke survivors, will experience executive dysfunction. Executive dysfunction reduces capacity to regain independence in activities of daily living (ADL), particularly when alternative movement strategies are necessary to compensate for limb weakness. Improving executive function may lead to increased independence with ADL. There are various cognitive rehabilitation strategies for training executive function used within clinical practice and it is necessary to determine the effectiveness of these interventions.

OBJECTIVES

To determine the effects of cognitive rehabilitation on executive dysfunction for adults with stroke or other non-progressive acquired brain injuries.

SEARCH METHODS

We searched the Cochrane Stroke Group Trials Register (August 2012), the Cochrane Central Register of Controlled Trials (The Cochrane Library, August 2012), MEDLINE (1950 to August 2012), EMBASE (1980 to August 2012), CINAHL (1982 to August 2012), PsycINFO (1806 to August 2012), AMED (1985 to August 2012) and 11 additional databases. We also searched reference lists and trials registers, handsearched journals and conference proceedings, and contacted experts.

SELECTION CRITERIA

We included randomised trials in adults after non-progressive acquired brain injury, where the intervention was specifically targeted at improving cognition including separable executive function data (restorative interventions), where the intervention was aimed at training participants in methods to compensate for lost executive function (compensative interventions) or where the intervention involved the training in the use of an adaptive technique for improving independence with ADL (adaptive interventions). The primary outcome was global executive function and the secondary outcomes were specific components of executive function, working memory, ADL, extended ADL, quality of life and participation in vocational activities. We included studies in which the comparison intervention was no treatment, a placebo intervention (i.e. a rehabilitation intervention that should not impact on executive function), standard care or another cognitive rehabilitation intervention.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened abstracts, extracted data and appraised trials. We undertook an assessment of methodological quality for allocation concealment, blinding of outcome assessors, method of dealing with missing data and other potential sources of bias.

MAIN RESULTS

Nineteen studies (907 participants) met the inclusion criteria for this review. We included 13 studies (770 participants) in meta-analyses (417 traumatic brain injury, 304 stroke, 49 other acquired brain injury) reducing to 660 participants once non-included intervention groups were removed from three and four group studies. We were unable to obtain data from the remaining six studies. Three studies (134 participants) compared cognitive rehabilitation with sensorimotor therapy. None reported our primary outcome; data from one study was available relating to secondary outcomes including concept formation and ADL. Six studies (333 participants) compared cognitive rehabilitation with no treatment or placebo. None reported our primary outcome; data from four studies demonstrated no statistically significant effect of cognitive rehabilitation on secondary outcomes. Ten studies (448 participants) compared two different cognitive rehabilitation approaches. Two studies (82 participants) reported the primary outcome; no statistically significant effect was found. Data from eight studies demonstrated no statistically significant effect on the secondary outcomes. We explored the effect of restorative interventions (10 studies, 468 participants) and compensative interventions (four studies, 128 participants) and found no statistically significant effect compared with other interventions.

AUTHORS' CONCLUSIONS

We identified insufficient high-quality evidence to reach any generalised conclusions about the effect of cognitive rehabilitation on executive function, or other secondary outcome measures. Further high-quality research comparing cognitive rehabilitation with no intervention, placebo or sensorimotor interventions is recommended.

Recent trends in rehabilitation interventions for visual neglect and anosognosia for hemiplegia following right hemisphere stroke

This article highlights the most recent findings regarding the rehabilitation interventions for the syndromes of visual neglect and anosognosia for hemiplegia that occur following right hemisphere stroke. We review papers published in the past 4 years pertaining to therapeutic approaches for these two syndromes in order to identify the trends in the development of effective interventions. Overall, it appears well recognized that visual neglect syndromes and awareness syndromes frequently co-occur and both include complex, multifaceted impairments leading to significant difficulties in daily life functioning following stroke. Thus, the interventions for these syndromes must be multifaceted in order to address the complex interplay of cognitive-behavioral-emotional components. There appears to be a trend for using combination therapeutic interventions that address these components.
