Effectiveness of a low intensity outpatient cognitive rehabilitation programme for patients in the chronic phase after acquired brain injury

Community-based practical behavioral intervention in public transportation for people with acquired brain injury: study of two cases using a single-case experimental design study

The purpose of this paper was to report on the progress of a behavioral approach to enable patients with acquired brain injury (age 57, male, stroke and age 36, old, female, TBI) using a community activity support center to commute alone using public transportation. In this study, two ABI patients were intervened to enable them to use public transportation. The frequency of intervention was once a month or once a week. The two community-dwelling adults each had post-ABI attention and memory deficits and anxiety. A-B-A single-case experimental design was employed for this study. The transportation route was stepped into multiple steps. Each step was scored in a unique way to determine the degree of assistance the participant received from others. This score was considered the main outcome. Tau-U analysis was used for statistical analysis. Statistically significant improvements in public transportation use were shown between baseline and intervention. There were no significant differences between the intervention and follow-up periods. The results suggest that behavioral interventions are beneficial in reacquiring the ability to use public transportation and that the intervention effects are sustained.

A Brief Period of Wakeful Rest after Learning Enhances Verbal Memory in Stroke Survivors

OBJECTIVE

Accumulating evidence suggests that wakeful rest (a period of minimal cognitive stimulation) enhances memory in clinical populations with memory impairment. However, no study has previously examined the efficacy of this technique in stroke survivors, despite the high prevalence of post-stroke memory difficulties. We aimed to investigate whether wakeful rest enhances verbal memory in stroke survivors and healthy controls.

METHOD

Twenty-four stroke survivors and 24 healthy controls were presented with two short stories; one story was followed by a 10-minute period of wakeful rest and the other was followed by a 10-minute visual interference task. A mixed factorial analysis of variance (ANOVA) with pairwise comparisons was used to compare participants' story retention at two time points.

RESULTS

After 15-30 minutes, stroke survivors (p = .002, d = .73), and healthy controls (p = .001, d = .76) retained more information from the story followed by wakeful rest, compared with the story followed by an interference task. While wakeful rest remained the superior condition in healthy controls after 7 days (p = .01, d = .58), the beneficial effect was not maintained in stroke survivors (p = .35, d = .19).

CONCLUSIONS

Wakeful rest is a promising technique, which significantly enhanced verbal memory after 15-30 minutes in both groups; however, no significant benefit of wakeful rest was observed after 7 days in stroke survivors. Preliminary findings suggest that wakeful rest enhances early memory consolidation processes by protecting against the effects of interference after learning in stroke survivors.

Randomised controlled clinical trial of a structured cognitive rehabilitation in patients with attention deficit following mild traumatic brain injury: study protocol

OBJECTIVES

To measure the clinical, structural and functional changes of an individualised structured cognitive rehabilitation in mild traumatic brain injury (mTBI) population.

SETTING

A single centre study, Malaysia.

PARTICIPANTS

Adults aged between 18 and 60 years with mTBI as a result of road traffic accident, with no previous history of head trauma, minimum of 9 years education and abnormal cognition at 3 months will be included. The exclusion criteria include pre-existing chronic illness or neurological/psychiatric condition, long-term medication that affects cognitive/psychological status, clinical evidence of substance intoxication at the time of injury and major polytrauma. Based on multiple estimated calculations, the minimum intended sample size is 50 participants (Cohen's d effect size=0.35; alpha level of 0.05; 85% power to detect statistical significance; 40% attrition rate).

INTERVENTIONS

Intervention group will receive individualised structured cognitive rehabilitation. Control group will receive the best patient-centred care for attention disorders. Therapy frequency for both groups will be 1 hour per week for 12 weeks.

OUTCOME MEASURES

Primary: Neuropsychological Assessment Battery-Screening Module (S-NAB) scores. Secondary: Diffusion Tensor Imaging (DTI) parameters and Goal Attainment Scaling score (GAS).

RESULTS

Results will include descriptive statistics of population demographics, CogniPlus cognitive program and metacognitive strategies. The effect of intervention will be the effect size of S-NAB scores and mean GAS T scores. DTI parameters will be compared between groups via repeated measure analysis. Correlation analysis of outcome measures will be calculated using Pearson's correlation coefficient.

CONCLUSION

This is a complex clinical intervention with multiple outcome measures to provide a comprehensive evidence-based treatment model.

ETHICS AND DISSEMINATION

The study protocol was approved by the Medical Research Ethics Committee UMMC (MREC ID NO: 2016928-4293). The findings of the trial will be disseminated through peer-reviewed journals and scientific conferences.

One-year follow-up results of a community-based treatment programme for people with acquired brain injury in the chronic phase

Purpose: This study evaluated the long-term effects of Brainz, a community-based treatment programme for adults with acquired brain injury in the chronic phase of the injury.Materials and methods: The treatment consisted of group modules and biweekly individual home training sessions. Of the 62 subjects who participated in the original effect study, 30 subjects were available for follow-up assessment. Selection bias analysis of baseline characteristics revealed no significant differences between the included and the excluded group. Baseline measurements were compared with follow-up measurements to assess effect consolidation after treatment cessation.Results: The increased level of patient satisfaction with social participation found one year after baseline, was maintained at follow-up. The positive effects on the number of perceived difficulties in daily life and need of care that were found one year after baseline measurements were no longer present. However, an additional improvement in self-reported overall health was observed. The decreased level of self-esteem measured one year after baseline, was no longer present at follow-up.Conclusions: Overall, this study suggests consolidation of the effects of this community-based treatment programme. Further enhancement of treatment effects could be established by the implementation of booster sessions or peer support groups. Future controlled studies are needed.Implications for rehabilitationAcquired brain injury can lead to consequences in a variety of life domains that can persist after patients return to their homes.A low-intensity community-based rehabilitation programme called Brainz demonstrated to improve patient satisfaction with societal participation and reduce perceived difficulties in daily life and need of care.This study suggests the consolidation of these effects.

Outcomes of a community-based treatment programme for people with acquired brain injury in the chronic phase: a pilot study

The objective of the study was to evaluate the outcomes of Brainz, a low intensity community-based treatment programme for people with acquired brain injury (ABI). Participants were 62 people with sustained ABI (5.2 years post-injury, SD = 4.5) and 35 family caregivers. Participants attended two to five cognitive and physical group modules and received two hours of individual home treatment every two weeks. Primary outcomes for people with ABI were participation, perceived difficulties in daily life and need of care, level of goal attainment, and self-esteem. Primary family caregiver outcome was perceived burden of care. Attrition rate of people with ABI was 24% (n = 15), and of family caregivers was 31% (n = 11). People with ABI were more satisfied with the level of their participation after completing Brainz (p < .01), but showed no change in participation frequency or in restrictions (both ps > .01). They perceived fewer difficulties in daily life and less need of care (both ps < .01). Also, in two cognitive modules people improved on their goal achievement (p < .01). However, their self-esteem was reduced (p < .01). Caregiver burden was reduced (p < .01). This study has provided preliminary evidence of the effectiveness of a combined group-based clinical and individual home-based treatment programme, but more research is needed, preferably in larger controlled studies.

Dysexecutive symptoms and carer strain following acquired brain injury: Changes measured before and after holistic neuropsychological rehabilitation

BACKGROUND

Following acquired brain injury (ABI), deficits in executive functioning (EF) are common. As a result many brain-injured patients encounter problems in every-day functioning, and their families experience significant strain. Previous research has documented the benefits of cognitive rehabilitation for executive dysfunction, and rehabilitation programmes designed to ameliorate functional problems associated with ABI.

OBJECTIVES

This study primarily aims to evaluate whether a neuropsychological rehabilitation programme reduces reported symptoms of everyday dysexecutive behaviour and carer strain.

METHODS

In this study 66 ABI outpatients attended comprehensive holistic neuropsychological rehabilitation programme. A repeated-measures design was employed to determine the effect of rehabilitation on EF and carer strain, as part of a service evaluation. Outcome measures comprised the dysexecutive questionnaire (DEX/DEX-I) and carer strain index (CSI), applied pre- and post-rehabilitation.

RESULTS

Results indicate rehabilitation benefited clients and carers in 5 of 6 DEX/DEX-I subscales, and 2 of 3 CSI subscales, (p < 0.05). An effect of aetiology on rehabilitation was found on the metacognitive scale of the DEX-I.

CONCLUSIONS

Therefore, this study supports a comprehensive holistic neuropsychological rehabilitation programme as effective in reducing reported symptoms of dysexecutive behaviour and carer strain following ABI.

Comparison of cognitive behavioral therapy and supportive psychotherapy for the treatment of depression following traumatic brain injury: a randomized controlled trial

OBJECTIVE

To determine the efficacy of 2 different interventions (cognitive behavioral therapy [CBT] and supportive psychotherapy [SPT]) to treat post-traumatic brain injury (TBI) depression.

PARTICIPANTS

A sample of 77 community-dwelling individuals with a TBI, and a diagnosis of depression. Participants were randomized into treatment conditions either CBT or SPT and received up to 16 sessions of individual psychotherapy.

MEASURES

Participants completed the Structured Clinical Interview for DSM-IV and self-report measures of depression (Beck Depression Inventory-Second Edition), anxiety (State-Trait Anxiety Inventory), perceived social support (Interpersonal Support Evaluation List), stressful life events (Life Experiences Survey), and quality of life (QOL) before beginning and immediately following treatment.

RESULTS

No significant differences were found at baseline between CBT and SPT groups on demographic factors (sex, age, education, race, and time since injury) or baseline measures of depression, anxiety, participation, perceived social support, stressful life events, or QOL. Analyses of variance revealed significant time effects for the Beck Depression Inventory-Second Edition, State-Trait Anxiety Inventory, and QOL outcome measures but no group effects. Intention-to-treat mixed effects analyses did not find any significant difference in patterns of scores of the outcome measures between the CBT and SPT intervention groups.

CONCLUSIONS

Both forms of psychotherapy were efficacious in improving diagnoses of depression and anxiety and reducing depressive symptoms. These findings suggest that in this sample of individuals with TBI, CBT was not more effective in treating depression than SPT, though further research is needed with larger sample sizes to identify different components of these interventions that may be effective with different TBI populations.

A process evaluation of a stroke-specific follow-up care model for stroke patients and caregivers; a longitudinal study

Background

There is a need for follow-up care after stroke, but there is no consensus about the way to organise it. An intervention providing follow-up care for stroke patients and caregivers showed favourable effects on the level of social activities, but no other effects were found. The intervention consists of a maximum of five home visits to patients and caregivers during a period of 18 months post-discharge. The home visits are conducted by a stroke care coordinator (SCC) using a structured assessment tool. The objective of this study was to examine process-related factors that could have influenced the effectiveness of the intervention.

Methods

77 stroke patients, 59 caregivers and 4 SCCs participated in the study. Data on the organisational characteristics of and the satisfaction with the intervention were collected by means of structured assessments, interviews and self-administered questionnaires at 1, 6, 12 and 18 months of follow-up. The intervention was provided between April 2008 and June 2011.

Results

Patients received an average of 3.8 home visits (SD 1.4) and 55% of them had a follow-up period of a maximum of 18 months. There were 1074 problems identified and the SCCs initiated 363 follow-up care and referral options. Stroke patients and caregivers were very satisfied with the intervention. The SCCs were satisfied with the assessment tool, but would like to see a structured referral system.

Conclusions

The intervention was only partially performed in accordance with the protocol and was positively evaluated by patients, caregivers and SCCs. It is recommended to add a structured referral system to the intervention.

Exploring the relation between learning style and cognitive impairment in patients with acquired brain injury

The way a patient prefers to approach or choose a learning situation represents the patient's learning style. The objective of this chart review study was to explore the relation between learning style and cognitive impairment in patients with acquired brain injury (ABI). We used data from files of 92 adult patients with ABI referred to inpatient rehabilitation, who completed the Adapted Learning Style Inventory (A-LSI) and at least one of the following neuropsychological tests: Trail Making Test, Rey Auditory Verbal Learning Test, WAIS-III Digit Span, Rey-Osterrieth Complex Figure Test-Copy, Stroop Color-Word Test, or the Brixton Spatial Anticipation Test. The A-LSI yielded the following distribution of learning styles: 4 doers, 48 observers, 2 deciders and 38 thinkers. No significant correlation coefficients were found between the neuropsychological tests and the A-LSI. Furthermore, Chi-square tests revealed no significant associations between learning style (observer, thinker) and cognitive impairment. The results of this exploratory study suggest that learning style and cognitive impairment are independent in patients with ABI.
