Investigation of factors related to employment outcome following traumatic brain injury: a critical review and conceptual model

Purpose: The purpose of this article is to critically review the literature to examine factors that are most consistently related to employment outcome following traumatic brain injury (TBI), with a particular focus on metacognitive skills. It also aims to develop a conceptual model of factors related to employment outcome.

Method: The first stage of the review considered 85 studies published between 1980 and December 2003 which investigated factors associated with employment outcome following TBI. English-language studies were identified through searches of Medline and PsycINFO, as well as manual searches of journals and reference lists. The studies were evaluated and rated by two independent raters (Kappa = 0.835) according to the quality of their methodology based upon nine criteria. Fifty studies met the criteria for inclusion in the second stage of the review, which examined the relationship between a broad range of variables and employment outcome.

Results: The factors most consistently associated with employment outcome included pre-injury occupational status, functional status at discharge, global cognitive functioning, perceptual ability, executive functioning, involvement in vocational rehabilitation services and emotional status.

Conclusions: A conceptual model is presented which emphasises the importance of metacognitive, emotional and social environment factors for improving employment outcome.     

Prognostic social factors in the subacute phase after a stroke for the discharge destination from the hospital stroke-unit. A systematic review of the literature

Purpose:?The objective of our study was to identify prognostic social factors in the subacute phase after stroke for the discharge destination from the hospital stroke-unit.

Methods:?A systematic literature search was performed, designed in accordance with the Cochrane Collaboration criteria. Internal, statistical and external validity of the studies were assessed using a checklist with 11 methodological criteria.

Results:?Characteristics of the social situation that proved to be important for prediction of the discharge destination are marital status and social support. Quantity and methodological quality of the research studies were insufficient, and the number of possible social prognostic factors investigated was limited by the absence of a conceptual framework of social subdomains in the studies, including an unambiguous definition of the prognostic social factors within these subdomains.

Conclusions:?A great need exists for research into the prognostic qualities of the following social factors: the ability to provide support, presence, and readiness of the homefront; the availability of professional care, personal financial means, membership of societies and clubs, frequency of contacts with close relatives and friends; the quality of the patient's residence with regard to the adaptation to the needs and abilities of the patient. A commitment about the aforementioned conceptual framework is mandatory.     

A framework for the conceptual modelling of assistive technology device outcomes

Purpose: A key step in planning assistive technology outcomes research is formulation of a conceptual model, specific to a particular type of device, that provides a rationale for the expected outcomes. This paper reflects the conviction that the development of device-specific causal models will be facilitated by having available an overarching framework that is potentially applicable to multifarious types of devices and their outcomes.

Method: A literature review identified the critical, unmet needs for a conceptual framework. The assumptions underlying the framework were specified preparatory to describing it and discussing its implications.

Results: The outcomes of assistive technology devices are depicted as resulting from the interaction among characteristics of a specific device-type, its users, and their environment. Initial junctures include procurement of a type of device and a period of introductory use that, interacting with various moderating co-factors, result in a variety of shorter-term outcomes, possible longer-term use, and its outcomes.

Conclusions: The framework has the potential of facilitating the development of device-specific causal models. It also may contribute to developing a research agenda for assistive technology outcomes research by highlighting measures that need to be developed and by identifying testable hypotheses concerned, for example, with the manner and duration of devices' usage.     

The value of the Rehabilitation Activities Profile (RAP) as a quality sub-system in rehabilitation medicine

Purpose: To determine whether interdisciplinary team care, using the Rehabilitation Activities Profile (RAP) as a team tool, results in a better rehabilitation outcome.

Method: A multilevel prospective cohort study, with a controlled before and after design. Eighteen rehabilitation teams in eight rehabilitation centres in the Netherlands and Belgium participated. Based on the level of implementation of the RAP, we compared three study groups. Consecutive adult patients (n = 933) with stroke, amputation of the lower limb, spinal cord injury, multiple sclerosis, or other neuromuscular disorders, were followed during inpatient or outpatient rehabilitation. Main outcome measures were Barthel Index, RAP-CPM (sum score of the domains communication, personal care and mobility), Nottingham Health Profile (NHP), length of rehabilitation (LOR) and discharge destination (home vs elsewhere).

Results: Overall results show that scores on the Barthel Index, the RAP-CPM and the NHP improved, on average, by 18.4%, 12.7%, and 6.7%, respectively. However, treatment from a rehabilitation team that uses the RAP was associated with a significantly lower Barthel score, and small, non-significant effects on the RAP-CPM and the NHP. Partial use of the RAP resulted in non-significant, lower scores on these measures. With respect to discharge destination and LOR, there were also no significant differences between the three study groups, with the exception of a shorter outpatient rehabilitation period for the group in which partial use was made of the RAP.

Conclusion: The RAP, at the current level of implementation, does not improve rehabilitation outcome.     

Toward a cognitive-affective model of goal-setting in rehabilitation: is self-regulation theory a key step?

Purpose: The aim of this article is to argue that self-regulation theory might offer a useful model for clinical practice, theory-building and empirical research on goal-setting in rehabilitation.

Method: Relevant literature on goal-setting and motivation in rehabilitation is considered and some problematic issues for current practice and future research are highlighted. Carver and Scheier's self-regulation theory and its application to rehabilitation research is examined.

Results: It is argued that self-regulation theory offers a robust theoretical framework for goal-setting and one in which the salient concepts of motivation and emotion are prominent.

Conclusions: Self-regulation theory offers a potentially useful heuristic framework for rehabilitation research.     

Is social participation associated with quality of life of older adults with physical disabilities?

Purpose: To explore the relationships between subjective quality of life and social participation of older adults with physical disabilities.

Method: A cross-sectional design was used with a convenience sample of 46 people aged 60 to 90 living in the community. Subjective quality of life was estimated with the Quality of Life Index and social participation with the Assessment of Life Habits.

Results: Only a weak relationship was found between total scores of quality of life and social participation. Interpersonal relationships, responsibilities, fitness and recreation were the categories of social participation most associated with quality of life. Social roles were more associated with quality of life than daily activities. Finally, satisfaction with the accomplishment of life habits was also more associated with quality of life than the performance itself.

Conclusions: The importance of social participation in regard to the quality of life of older persons with physical disabilities living in the community is partially supported by these findings. Other studies are needed to clarify how social participation influences quality of life in this population.     

Functional outcome in patients with critical illness polyneuropathy

Purpose: To evaluate the functional outcome of intensive care patients with critical illness polyneuropathy (CIP), 6 and 12 months after the onset.

Methods: Design: A prospective observational cohort study and a cross-sectional study.

Setting: University hospital in the Netherlands.

Patients: Eight consecutive intensive care patients with CIP for the prospective study and eight patients diagnosed with CIP in the past 6 months for the cross-sectional study.

Main outcome measures: Functional outcome regarding body functions and structure, activities, participation and perceived quality of life.

Results: Nine patients (56%) died within one year. Functional outcome, participation and subjective health status in survivors varied widely at 6 and 12 months. After 12 months, physical functioning was improved in all patients. However activities related to mobility outdoors, autonomy, participation and quality of life were restricted in most patients.

Conclusions: The majority of survivors have persistent functional disabilities in activities, reduced quality of life and restrictions in autonomy and participation one year after the onset of CIP. Prolonged rehabilitation treatment is necessary for an increasing number of intensive care patients who develop CIP, in order to reduce handicaps and achieve optimal autonomy and social participation.     

External validation of a housing recommendation model for clients following stroke rehabilitation

Purpose: Using a Social Judgment Theory approach, mathematical models of clinical decisions can be developed to predict new decisions. However, since these models are often developed under 'laboratory conditions' using hypothetical cases rather than real world client samples, questions may be raised concerning the external validity of such models. The purpose of this research was to validate a discharge housing decision making model developed with hypothetical clients with stroke with a real sample. This process is referred to as external validation.

Method: Cross-tabulations were performed to compare the model discharge housing prediction against the team's actual recommendations for 60 clients from three rehabilitation centres. A sensitivity and specificity analysis was used to compare the model predictions against the client's actual discharge housing.

Results: A simple mathematical model was constructed to accurately predict housing recommendations. However, the predictive power of the model appeared to be limited by clinician/team consideration of unmeasured factors such as client personality and motivation.

Conclusion: It is suggested that the housing decision model developed may be useful for rehabilitation teams as a starting point when discussing the best place to recommend a client reside on discharge from rehabilitation. Such a model may assist teams to standardise their decision processes and minimise the potential for unwarranted bias.     

A comparison of consumer-directed and agency-directed personal assistance services programmes

Purpose: To compare a consumer-directed personal assistance services (PAS) programme with an agency-directed PAS programme.

Method: A convenience sample was used for this cross-sectional study with one data collection point. Outcomes were compared for consumer-directed and agency-directed PAS. Hierarchical regressions were also used to determine the predictors of outcomes across PAS programmes. In-home interviews were conducted by a trained data collector from April 2000 to December 2001.

Results: Participants in the consumer-directed programme reported more choices over PAS and satisfaction with PAS. Self-reported outcomes were primarily predicted by the following variables: service arrangement, type of provider, importance of directing PAS, health status, number of personal assistants used in past 12 months, sufficient PAS hours received, and social support.

Conclusions: Consumer-directed PAS enhances outcomes for many persons with disabilities. Self-reported outcomes are affected by many factors that could be addressed in PAS programme development.     

Learning to eat after radiation therapy for throat cancer

Purpose: The initial purpose was to find more expedient ways for learning to eat for personal rehabilitation. The secondary purposes were to inform other radiation therapy patients and to inform clinicians and therapists involved in rehabilitation of throat cancer patients.

Method: This is an account of personal experiences of the author who is a throat cancer survivor. This rehabilitation engineer, and his social worker wife, systematically sought and found more effective ways for learning to eat again.

Results: More effective approaches for discovering, preparing, presenting and consuming food by recovering throat cancer patients were identified.

Conclusion: The rehabilitation process for patients with radiation damage to the throat can be enhanced through simple methods and dedicated efforts of the patients themselves.     

Measuring fatigue in people with multiple sclerosis

Objective: To compare methods of assessing fatigue.

Design: Cross sectional.

Setting: Community.

Subjects: Forty Multile Sclerosis (MS) patients and 20 healthy controls.

Main outcome measures: Fatigue questionnaires, SDSA dot cancellation test, finger tapping test, TEA Lottery.

Results: The MS patients had significantly higher levels of fatigue than the controls on the Task Induced Fatigue Scale, Fatigue Severity Scale and Fatigue Impact Scale. The Task Induced Fatigue Scale completed whilst imagining oneself driving and the Fatigue Assessment Instrument did not differentiate between MS patients and controls. Finger tapping differentiated between MS patients and controls but there was no significant difference between MS patients and controls on visual and auditory concentration tests. A factor analysis indicated that questionnaire measures of fatigue were inter-related but independent of objective test performance.

Conclusions: Questionnaire measures can be used to assess fatigue in people with MS. The FSS differentiated MS patients from controls and is relatively short. It was therefore recommended for clinical use.     

A two-year longitudinal study of social support following amputation

Purpose: (1) To describe one aspect of social support, social integration, longitudinally for 2 years following lower limb amputation and (2) to explore the impact of social support on depression, pain interference, life satisfaction, mobility, and occupational functioning.

Method: Eighty-nine adults recruited from consecutive admissions to an orthopaedic surgery service completed telephone interviews 1, 6, 12 and 24 months following amputation surgery. Dependent variables included the Social Integration (SI) sub-scale of the Craig Handicap Assessment and Reporting Technique (CHART) and the Multidimensional Scale of Perceived Social Support (MSPSS).

Results: There was a high level of SI among most persons following lower limb amputations that was relatively unchanged in the 2 years following surgery. However, mean levels of SI were lower in this group compared to a sample without disabilities. MSPSS scores were highly variable, ranging from almost no support to the maximum amount of support. MSPSS was an important concurrent predictor of pain interference, life satisfaction, and mobility, controlling for demographic and amputation-related factors. Baseline MSPSS predicted mobility and occupational functioning 6 months post-amputation, controlling for demographic and amputation-related factors.

Conclusions: Findings suggest that interventions aimed at improving the quality of social relationships after amputation may facilitate participation in activities.     

Predictors of long-term participation after stroke

Purpose: (1) To explore factors that predict long-term participation after stroke (2 - 4 years after discharge from rehabilitation), and (2) to determine factors that predict both short- and long-term participation.

Methods: Biopsychosocial data of people who had had a stroke were measured at discharge from an intensive rehabilitation unit using valid instruments. Six months later (n = 102) as well as 2 - 4 years later (n = 66), social participation of the survivors was measured in their living environments. Participation was estimated with the Assessment of Life Habits (LIFE-H), which includes 12 categories of daily activities and social roles.

Results: From mutivariate regression analyses, the best predictors of long-term participation after stroke appear to be age, comorbidity, motor coordination, upper extremity ability and affect. Age, comorbidity, affect and lower extremity coordination are the best predictors of participation after stroke at both measurement times.

Conclusions: With the exception of age, these factors may be positively modified and thus warrant special attention in rehabilitation interventions.     

Phantom pain: A sensitivity analysis

Purpose: To analyse how decisions to dichotomise the frequency and impediment of phantom pain into absent and present influence the outcome of studies by performing a sensitivity analysis on an existing database.

Method: Five hundred and thirty-six subjects were recruited from the database of an orthopaedic workshop and filled out a questionnaire in which the following items were assessed: demographics, side, date, level and reason of amputation, presence and frequency of phantom sensations, phantom pain and stump pain, and impediment due to phantom pain.

Results: The prevalence of phantom pain ranged from 7 - 72% when different cut off points for the frequency of phantom pain were applied. The significance of the various risk factors for the prevalence of phantom pain changed when different cut off points were applied. Only stump pain and phantom sensations were significant risk factors for all cut off points. Risk factors for the impediment of phantom pain changed when different cut off points were applied and these risk factors were different from those for the prevalence of phantom pain.

Conclusion: The choice of cut off points influences the outcome of phantom pain studies considerably. This study provides some insight into the differences in prevalence and risk factors found in literature.     

Client,needs assessor and agency-related factors predicting allocation of electric scooters to community-dwelling elderly in The Netherlands: a vignette study

Purpose: To determine what client factors predict allocation of an electric scooter and to determine what needs assessor and agency factors explain variation in decision-making by long-term care needs assessors concerning clients requesting electric scooters.

Method: Hypothetical case vignettes were sent to needs assessors allocating services for the elderly, and questionnaires were used to obtain organizational and individual needs assessor data. Multilevel logistic regression analysis provided random and fixed effects.

Results: The decision whether or not to allocate an electric scooter was influenced primarily by the clients' driving safety, their disabilities and whether or not there were possibilities to stall the electric scooter. Transportation goals and the clients' activity level were not taken into account. There was some random variation on the level of needs assessors.

Conclusions: A system whereby all clients who request an electric scooter, have disabilities that limit mobility, have shown to be safe drivers and have a shed to stall the scooter are allocated a scooter may be more appropriate in maintaining elderly persons' independence and preventing social isolation. Regular evaluation afterwards and extra driving lessons may prevent allocation of scooters to clients who do not use them.     

The efficiency of electromagnetic field treatment in Complex Regional Pain Syndrome Type I

Introduction: Complex Regional Pain Syndrome Type I is a pathological condition that occurs without evident nerve injury and follows a course characterized by severe pain.

Purpose: The aim of this study is to assess whether or not electromagnetic field treatment administered with calcitonin and exercise has positive effects on clinical improvement, scintigraphic assessment and bone markers compared to calcitonin and exercise administration.

Method: In this randomized double-blind, placebo-controlled study, 40 patients with Complex Regional Pain Syndrome Type I, that developed after a Colles fracture were included in the assessments and were administered calcitonin and exercise treatment for 6 weeks. In addition to this treatment, half the patients received electromagnetic field treatment, and the other half received placebo treatment. The patients were evaluated at the beginning and end of treatment with clinical parameters, scintigraphic assessment and biochemical markers.

Results: Although we found some significant improvements in our evaluation criteria, we could not find a significant statistical difference between groups.

Conclusions: The absence of a significant difference between the two groups in the assessment parameters has been interpreted as evidence that electromagnetic field treatment does not provide additional benefit to calcitonin and exercise treatment.     

Theoretical aspects of goal-setting and motivation in rehabilitation

Purpose: The purpose of this article is to provide rehabilitation theorists and researchers with an introduction to some key theories of goals and motivation from the field of social cognition and to argue for increased dialogue between the two disciplines.

Method: The use of goals and goal-setting in rehabilitation is briefly surveyed and the somewhat ambivalent attitude toward the concept of motivation in the rehabilitation literature is highlighted. Three major contributors to the study of goals and motivation from the field of social cognition are introduced and their work summarized. They include: (i) Deci and Ryan's Self-Determination Model; (ii) Emmons' work on goals and personal strivings, and (iii) Karniol and Ross' discussion of temporal influences on goal-setting.

Results: It is argued that there is a need for a greater emphasis upon theory development in rehabilitation research and that closer collaboration between researchers in rehabilitation and social psychology offers considerable promise. Instances where the three theories from social cognition might have relevance to clinical rehabilitation settings are described. Some possible directions for research are also briefly sketched.

Conclusion: Both rehabilitation and social cognition have much to gain from increased dialogue.     

Long-term outcomes after moderate to severe traumatic brain injury

Objective: This research examined the long-term outcomes of rehabilitation patients with moderate to severe traumatic brain injury (TBI).

Design: Retrospective cohort study.

Setting and subjects: We examined consecutive records of persons with moderate to severe traumatic brain injury who were discharged from a large rehabilitation hospital in Pennsylvania from 1973 to 1989. We interviewed consenting participants (n = 306) up to 24 years post-injury.

Main outcome measures: Self-rated health, activity limitations, employment, living arrangements, marital status, Community Integration Questionnaire, and use of rehabilitation services.

Results: Participants were most limited in activities such as managing money and shopping. Twenty-nine per cent of our participants were working full time. There were significant relationships between activity limitations and residual cognitive impairment at follow-up. Self-rated health was correlated with most instrumental activities of daily living.

Conclusion: Our findings document health and function in a large post acute TBI population and implications for rehabilitation are discussed.     

Psychological factors after traumatic amputation in landmine survivors: The bridge between physical healing and full recovery

Purpose: Limb loss due to a landmine injury is sudden and devastating. The resulting disability makes life challenging in a world where physical ability is the 'norm'. In order to better understand the psychological adjustments individuals make in their recovery from a landmine injury, the Landmine Survivors Network conducted an exploratory qualitative study to determine factors that contribute to an individual's recovery. The study examined psychosocial aspects, coping strategies, and resilience characteristics of limb loss survivors across differing cultural, societal and economic backgrounds.

Method: Eighty-five participants (68 persons of limb loss, 10 family members, seven service providers) were interviewed using a semi-structured protocol in the USA and an open-ended format in six landmine affected countries. Data analysis was completed using grounded theory analytic strategies.

Results: Data indicated that the survivors' acceptance of limb loss and their state of psychological recovery were greatly influenced by the individual's resilience characteristics, social support, medical care, economic situation and societal attitudes toward people with disabilities.

Conclusion: Recovery from traumatic amputation in landmine survivors needs to be comprehensive and coordinated, and requires addressing the individual's physical, psychological, economic and social needs within the context of family, community, and the socio-cultural environment in which they live.     

The development of a clinical practice stroke guideline for physiotherapists in The Netherlands: a systematic review of available evidence

Purpose. To develop a clinical practice guideline for the physiotherapy management of patients with stroke as support for the clinical decision-making process, especially with respect to the selection of appropriate interventions, prognostic factors and outcome measures.

Introduction. Physiotherapists have a high caseload of patients with stroke, so there is a need to identify effective evidence-based physiotherapy procedures. The availability of a guideline that includes information about prognostic factors, interventions, and outcome measures would facilitate clinical decision-making.

Method. A systematic computerized literature search was performed to identify evidence concerning the use of: (i) prognostic factors related to functional recovery; (ii) physiotherapy interventions in patients with stroke; and (iii) outcome measures to assess patients' progress in functional health. Experts, physiotherapists working in the field of stroke rehabilitation, and a multidisciplinary group of health professionals reviewed the clinical applicability and feasibility of the recommendations for clinical practice and their comments were used to compose the definitive guideline.

Results. Of 9482 relevant articles, 322 were selected. These were screened for methodological quality. Seventy-two recommendations for clinical practice were retrieved from these articles and included in the guideline: Six recommendations concerned the prediction of functional recovery of activities of daily living (ADL), including walking ability and hand/arm use; 65 recommendations concerned the choice of physiotherapy interventions; and 1 recommendation concerned the choice of outcome instrument to use. A core set of seven reliable, responsive, and valid outcome measures was established, to determine impairments and activity limitations in patients with stroke.

Conclusions. The guideline provides physiotherapists with an evidence-based instrument to assist them in their clinical decision making regarding patients with stroke. As most of the recommendations included in the guideline came from studies of patients in the post acute and chronic phase of stroke, and in general involved patients with less severe and uncomplicated stroke, more needs to be learned about the more complex cases.
