Effects of whole-body vibration training on physical function, activities of daily living, and quality of life in patients with stroke: a systematic review and meta-analysis

Purpose: This systematic review and meta-analysis aimed to evaluate the efficacy of whole-body vibration training (WBVT) in patients with stroke, specifically focusing on its effects on physical function, activities of daily living (ADL), and quality of life (QOL). Additionally, potential moderators influencing WBVT outcomes were explored. Methods: We conducted a systematic search of PubMed, Embase, and Cochrane Library from inception to September 2022. Eligible studies were randomized controlled trials employing WBVT in patients with stroke. Two investigators independently extracted the data and calculated the standardized mean difference (SMD) using random-effect models. Results: Twenty-five studies involving 991 patients were included in this meta-analysis. WBVT demonstrated significant reductions in spasticity (SMD = -0.33, 95% CI = -0.61 to -0.06, p = 0.02), improvements in motor function (SMD = 0.39, 95% CI = 0.16 to 0.61, p < 0.01), and enhancements in balance function (SMD = 0.28, 95% CI = 0.09 to 0.47, p < 0.01) in patients with stroke. However, no significant effects were observed for gait (SMD = -0.23, 95% CI = -0.50 to 0.04, p = 0.10), ADL (SMD = -0.01, 95% CI = -0.46 to 0.44, p = 0.97), or QOL (SMD = 0.12, 95% CI = -0.30 to 0.53, p = 0.59). Subgroup analyses revealed that variable frequency vibration and side-alternating vibration exhibited significant efficacy in reducing spasticity and improving motor and balance functions, while fixed frequency vibration and vertical vibration did not yield significant therapeutic benefits in these domains. Conclusion: Our findings indicate that WBVT may serve as a viable adjunct therapy for stroke patients to alleviate spasticity and enhance motor and balance functions. Variable frequency and side-alternating vibration appear to be crucial factors influencing the therapeutic effects of WBVT on these dysfunctions. Nonetheless, WBVT did not show significant effects on gait, ADL, or QOL in stroke patients. Systematic Review Registration: https://www.crd.york.ac.uk/PROSPERO/, identifier (CRD42022384319).

Translation and cross-cultural adaptation of the Brazilian version of the PM-Scale: A specific measure of participation after stroke

BACKGROUND

The PM-Scale was developed specifically to assess participation in individuals after stroke based on the concepts contained in the International Classification of Functioning, Disability and Health. However, this measure is only available in English and French.

OBJECTIVE

To translate and cross-culturally adapt the PM-Scale to Brazilian Portuguese, followed by the validation and testing of reliability of the translated version.

METHODS

The translation process followed standard guidelines. Preliminary test-retest reliability was determined using the intraclass correlation coefficient (ICC_2,1). The Rasch model was employed to analyse the validity, unidimensionality, invariance, and internal consistency of the Brazilian version of the PM-Scale.

RESULTS

The final translated version of the PM-Scale presented appropriate semantic, idiomatic, cultural, and conceptual equivalence. The preliminary analysis revealed excellent intra-observer and inter-observer reliability (ICC_2,1 = 0.91; 95%CI: 0.83, 0.95 and ICC_2,1 = 0.81; 95%CI: 0.64, 0.89, respectively). The analysis of the Rasch model revealed only one erratic item. An excellent overall fit was found for items (mean ± SD = 0.01 ± 1.02) and adequate fit was found for persons (mean ± SD = 1.16 ± 0.88). Internal consistency was considered adequate (person separation index = 1.77, reliability = 0.76). No significant invariance was found with regards to the personal characteristics of the sample (p > 0.05).

CONCLUSION

The Brazilian version of the PM-Scale is a valid, unidimensional, linear, reliable scale for measuring participation in stroke survivors and can be administered in less than five minutes.

Use of the International Classification of Functioning, Disability and Health (ICF) to expand and standardize the assessment of quality-of-life following a stroke: proposal for the use of codes and qualifiers

PURPOSE

Propose a way of coding and qualifying HRQoL following a stroke using the codes and qualifiers of the International Classification of Functioning, Disability and Health (ICF).

METHODS

An observational, cross-sectional study was conducted involving 51 individuals with hemiparesis resulting from a stroke. ICF codes related to the Stroke Specific Quality of Life (SS-QOL) scale were listed and subsequently classified using the generic ICF qualifiers, which range from .0 - no impairment to .4 - complete impairment. A simple mathematic calculation was proposed to convert the SS-QOL scores into ICF qualifiers.

RESULTS

The use of the ICF qualifiers revealed that the individuals exhibited a moderate level (.2) of quality of life, with mild impairment (.1) regarding upper limb function, language, self-care, and vision as well as severe impairment (.3) regarding social relations.

CONCLUSIONS

The proposal presented in this study allowed qualifying 43 ICF codes related to quality of life after a stroke in a simple, standardized manner, enabling the identification of different levels of impairment on each of the domains of the SS-QOL scale. This coding standardizes the evaluation, facilitates communication between healthcare providers, and systematizes the collection of data and information on health.Implications for rehabilitationProposal for qualifying concepts related to body functions, activity & participation, and environmental factors in a simple, standardized manner.The proposed mathematic calculation is simple and easy to understand, which minimizes the occurrence of errors.Possibility to identify different levels of impairment in each of the domains of the Stroke Specific Quality of Life scale, facilitating the establishment of individualized, longitudinal care.The ICF codes standardize the evaluation, facilitate communication between healthcare providers, and systematize the collection of data and information on health and functioning.

Linking of concepts measured by SATIS-Stroke and the PM-Scale to the international classification of functioning, disability and health

BACKGROUND

Rules have been developed to simplify the understanding of researchers/clinicians and standardize the linking process between concepts contained in the items on assessment measures and the International Classification of Functioning, Disability, and Health (ICF).

OBJECTIVE

Link the concepts of the SATISPART Stroke (SATIS-Stroke) and Participation Measurement Scale (PM-Scale) to ICF codes.

METHODS

Linking was performed by two evaluators with experience in the ICF taxonomy who applied the ten standard linking rules specifically developed and updated for this purpose. The level of agreement between the evaluators was determined using the Kappa coefficient with 95% confidence intervals.

RESULTS

The SATIS-Stroke and PM-Scale address the nine domains of the ICF "Activities and Participation" component. Adequate agreement was found between the researchers during the linking process, mainly between the 1º and 3º evaluators. Identified 41 ICF codes were found among the SATIS-Stroke items and 24 ICF codes were found among the items of the PM-Scale.

CONCLUSION

SATIS-Stroke addresses more issues regarding the domains of Learning and Applying Knowledge, Mobility, Self-Care, Domestic Life, and Major Life Areas, whereas the PM-Scale addresses more issues regarding the General Tasks and Demands, Communication, and Community, Social and Civic Life. Both instruments equally address issues related to Interpersonal Interactions and Relationships.

Use of artificial intelligence as an instrument of evaluation after stroke: a scoping review based on international classification of functioning, disability and health concept

Introduction: To understand the current practices in stroke evaluation, the main clinical decision support system and artificial intelligence (AI) technologies need to be understood to assist the therapist in obtaining better insights about impairments and level of activity and participation in persons with stroke during rehabilitation. Methods: This scoping review maps the use of AI for the functional evaluation of persons with stroke; the context involves any setting of rehabilitation. Data were extracted from CENTRAL, MEDLINE, EMBASE, LILACS, CINAHL, PEDRO Web of Science, IEEE Xplore, AAAI Publications, ACM Digital Library, MathSciNet, and arXiv up to January 2021. The data obtained from the literature review were summarized in a single dataset in which each reference paper was considered as an instance, and the study characteristics were considered as attributes. The attributes used for the multiple correspondence analysis were publication year, study type, sample size, age, stroke phase, stroke type, functional status, AI type, and AI function. Results: Forty-four studies were included. The analysis showed that spasticity analysis based on ML techniques was used for the cases of stroke with moderate functional status. The techniques of deep learning and pressure sensors were used for gait analysis. Machine learning techniques and algorithms were used for upper limb and reaching analyses. The inertial measurement unit technique was applied in studies where the functional status was between mild and severe. The fuzzy logic technique was used for activity classifiers. Conclusion: The prevailing research themes demonstrated the growing utility of AI algorithms for stroke evaluation.

Instrumentos da prática clínica com versão em português e a abrangência de seus conteúdos usando a CIF como referência: uma revisão sistemática

RESUMO A prática clínica tem sido subsidiada por instrumentos que permitem acessar e registrar informações de funcionalidade e saúde dos indivíduos. Uma forma de conhecer qual conteúdo da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) os instrumentos contemplam é usá-la como referência para auxiliar o profissional na escolha do mais adequado para acessar informações biopsicossociais. O objetivo foi identificar instrumentos da prática clínica em saúde que tiveram seu conteúdo ligado com a CIF e a existência de versão na língua portuguesa deles. Para tanto foi realizada uma revisão sistemática nas bases de dados SciELO Brasil, Lilacs e PubMed com os descritores “CIF”, “questionário” e “regra de ligação” em português e inglês. Três pesquisadores independentes realizaram a seleção, e o nível de concordância foi obtido pelo coeficiente Kappa.

O coeficiente Kappa mostrou concordância entre moderada e boa (p<0,001). Este estudo apresentou um panorama da ligação de conteúdo de instrumentos da prática clínica à CIF identificando quais têm versão em língua portuguesa, o que contribuirá para o potencial fortalecimento da abordagem biopsicossocial dos profissionais de saúde.

Stroke-Specific Quality of Life one-year post-stroke in two Scandinavian country-regions with different organisation of rehabilitation services: a prospective study

Purpose: To compare stroke-specific health related quality of life in two country-regions with organisational differences in subacute rehabilitation services, and to reveal whether organisational factors or individual factors impact outcome.Materials and methods: A prospective multicentre study with one-year follow-up of 369 first-ever stroke survivors with ischaemic or haemorrhagic stroke, recruited from stroke units in North Norway (n = 208) and Central Denmark (n = 161). The 12-domain Stroke-Specific Quality of Life scale was the primary outcome-measure.Results: The Norwegian participants were older than the Danish (M_age= 69.8 vs. 66.7 years, respectively), had higher initial stroke severity, and longer stroke unit stays. Both cohorts reported more problems with cognitive, social, and emotional functioning compared to physical functioning. Two scale components were revealed. Between-country differences in the cognitive-social-mental component showed slightly better function in the Norwegian participants. Depression, anxiety, pre-stroke dependency, initial stroke severity, and older age were substantially associated to scale scores.Conclusions: Successful improvements in one-year functioning in both country-regions may result from optimising long-term rehabilitation services to address cognitive, emotional, and social functioning. Stroke-Specific Quality of Life one-year post-stroke could be explained by individual factors, such as pre-stroke dependency and mental health, rather than differences in the organisation of subacute rehabilitation services.IMPLICATIONS FOR REHABILITATIONThe stroke-specific health related quality of life (SS-QOL) assessment tool captures multidimensional effects of a stroke from the perspective of the patient, which is clinically important information for the rehabilitation services.The cognitive-social-mental component and the physical health component, indicate specific functional problems which may vary across and within countries and regions with different organisation of rehabilitation services.For persons with mild to moderate stroke, longer-term functional improvements may be better optimised if the rehabilitation services particularly address cognitive, emotional, and social functioning.

Animal‐assisted therapy, including animal‐assisted activities and resident animals, for improving quality of life in people with stroke

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

To assess the effects of animal‐assisted therapy for improving quality of life for people with stroke. A secondary objective is to assess outcomes relating to the feasibility and potential barriers of providing animal‐assisted therapy for stroke patients, including recruitment, cost, adherence, and attrition.

Identification of categories of the International Classification of Functioning, Disability and Health in functional assessment measures for stroke survivors: a systematic review

Objective: Perform a systematic review to identify the categories of the International Classification of Functioning, Disability and Health linked to the concepts measured by functional assessment tools validated for Brazilian Portuguese: Timed Up and Go test, Functional Independence Measure, Barthel Index, and Rivermead Mobility Index and Modified Rankin Scale.Methods: The Medline, Embase and CINAHL databases were consulted using a standardized search strategy. The studies were summarized using a pre-established set of specific criteria for the adequate linkage between the concepts identified in the assessment measures and the International Classification of Functioning, Disability and Health categories. Two independent reviewers performed the selection of the studies, data extraction and evaluation of the results.Results: The search of the databanks led to the retrieval of 99 studies. However, only six articles were included in the present review. The linkage results of the studies included in the review were divergent, likely due to the taxonomic complexity of the International Classification of Functioning, Disability and Health, the difficulty in clearly relating the concepts of the assessment measures to the classifications and the fact that not all linkage rules were followed. "Activities and participation" was the most evaluated component, with mobility the most frequently covered category in the measures, followed by self-care. Among the measures analyzed, the Functional Independence Measure addresses a greater number of categories and therefore has the most concepts related to the International Classification of Functioning, Disability and Health, followed by the Barthel Index, Modified Rankin Scale, Rivermead Mobility Index and Timed Up and Go test. The Modified Rankin Scale was the assessment tool that most evaluated categories related to environmental factors.Conclusion: The Functional Independence Measure has more concepts related to the International Classification of Functioning, Disability and Health, since it addresses a greater number of categories. These findings can help guide health professionals in the selection of assessment tools for the evaluation of post-stroke functioning, making viable the use of the International Classification of Functioning, Disability and Health categories in clinical practice and public health services.Implications for rehabilitationThis study standardized identification of the International Classification of Functioning, Disability and Health categories in the main outcome measures used to assess post-stroke functional capacity.Functional Independence Measure has more concepts related to the International Classification of Functioning, Disability and Health compared to other functional assessment instruments.Findings can enable physiotherapists and researchers choose the most appropriate measure that best corresponds to their field of interest.These results facilitate the implementation of the International Classification of Functioning, Disability and Health in clinical practice.Use of International Classification of Functioning, Disability and Health categories can standardize information on functional health.

Improved quality of life following constraint-induced movement therapy is associated with gains in arm use, but not motor improvement

BACKGROUND

Constraint-induced movement therapy (CI therapy) is one of few treatments for upper extremity (UE) hemiparesis that has been shown to result in motor recovery and improved quality of life in chronic stroke. However, the extent to which treatment-induced improvements in motor function versus daily use of the more affected arm independently contribute to improved quality of life remains largely unexplored.

OBJECTIVE

The objective of this study is to identify whether motor function or daily use of a hemiparetic arm has a greater influence on quality of life after CI therapy.

METHODS

Two cohorts of participants with chronic stroke received either in-person CI therapy (n = 29) or video-game home-based CI therapy (n = 16). The two cohorts were combined and the motor-related outcomes (Wolf Motor Function Test, Action Research Arm Test, Motor Activity Log [MAL]) and quality of life (Stroke-Specific Quality of Life) were jointly modeled to assess the associations between outcomes.

RESULTS

The only outcome associated with improved quality of life was the MAL. Improvements in quality of life were not restricted to motor domains, but generalized to psychosocial domains as well.

CONCLUSIONS

Results suggest that improved arm use during everyday activities is integral to maximizing quality of life gains during motor rehabilitation for chronic post-stroke UE hemiparesis. In contrast, gains in motor function were not associated with increases in quality of life. These findings further support the need to implement techniques into clinical practice that promote arm use during daily life if improving quality of life is a main goal of treatment.

Intensive, functional training leads to optimal outcomes in a young woman post brain stem hemorrhage due to cerebral cavernous malformation

PURPOSE

Cerebral cavernous malformations (CCMs) can cause intracranial hemorrhages and account for 5-15% of all cerebral vascular malformations. The purpose of this retrospective case report is to describe the unusual motor recovery of a young woman following a large hemorrhage of a previously unknown brainstem CCM, otherwise not reported in the literature. Case Description: The patient was a 29-year-old female who presented with severe hemiparesis on the left 6 weeks after a first-ever hemorrhage. She had demonstrated minimal improvement in her motor recovery to date, was dependent on a walker for ambulation, and had no distal left upper extremity function. An intensive evidence-based plan of care over 6 weeks included progressive task-specific strengthening, treadmill training, and dynamic balance training. Outcomes: The patient achieved complete motor recovery, indicated by improvement from 23/66 to 64/66 in the Fugl-Meyer Upper Extremity Subscale score and from 12/30 to 30/30 in the Functional Gait Assessment. She returned to independent ambulation with functional gait speeds and kinematics. Discussion: This case report demonstrates an unusual clinical course of unexpected full recovery in a young woman after a large brainstem CCM after an intensive 6-week course of physical therapy. Other patients with a similar presentation after CCM may benefit from an intensive plan of care. Clinicians should be aware of the possibility of unusual recovery in this population as not to limit expectations for recovery.

FIT for FUNCTION: study protocol for a randomized controlled trial

BACKGROUND

The current state of evidence suggests that community-based exercise programs are beneficial in improving impairment, function, and health status, and are greatly needed for persons with stroke. However, limitations of these studies include risk of bias, feasibility, and cost issues.

METHODS/DESIGN

This single-blinded, randomized controlled trial (RCT) of 216 participants with stroke will compare the effectiveness of a 12-week YMCA community-based wellness program (FIT for FUNCTION) specifically designed for community-dwelling persons with stroke to persons who receive a standard YMCA membership. The primary outcome will be community reintegration using the Reintegration to Normal Living Index at 12 and 24 weeks. Secondary outcomes include measurement of physical activity level using the Rapid Assessment of Physical Activity and accelerometry; balance using the Berg Balance Scale; lower extremity function using the Short Physical Performance Battery; exercise capacity using the 6-min walk test; grip strength and isometric knee extension strength using hand held dynamometry; and health-related quality of life using the European Quality of Life 5-Dimension Questionnaire. We are also assessing cardiovascular health and lipids; glucose and inflammatory markers will be collected following 12-h fast for total cholesterol, insulin, glucose, and glycated hemoglobin. Self-efficacy for physical activity will be assessed with a single question and self-efficacy for managing chronic disease will be assessed using the Stanford 6-item Scale. The Patient Activation Measure will be used to assess the patient's level of knowledge, skill, and confidence for self-management. Healthcare utilization and costs will be evaluated. Group, time, and group × time interaction effects will be estimated using generalized linear models for continuous variables, including relevant baseline variables as covariates in the analysis that differ appreciably between groups at baseline. Cost data will be treated as non-parametric and analyzed using a Mann-Whitney U test.

DISCUSSION

This is a RCT with broad study eligibility criteria intended to recruit a wide spectrum of individuals living in the community with stroke. If positive benefits are demonstrated, results will provide strong research evidence to support the implementation of structured, community-based exercise and education/self-management programs for a broad range of people living in the community with stroke.

Functioning in patients with schizophrenia: a systematic review of the literature using the International Classification of Functioning, Disability and Health (ICF) as a reference

PURPOSE

To identify and quantify the main concepts included in published studies focusing on individuals with schizophrenia using the International Classification of Functioning, Disability and Health (ICF).

METHODS

Searches (limited to those published from 2008 to 2012) were performed in MEDLINE, PsycINFO and CINAHL. Included studies described participants with schizophrenia, were original articles and included only subjects who were at least 18 years of age at study entry. All concepts underlying the measures and the text of the articles were extracted, and they were linked to ICF categories using standardized rules.

RESULTS

From the 3584 abstracts retrieved, 348 were randomly selected, and of these, 206 studies met the inclusion criteria. A total of 17,141 concepts were extracted, 84.8% of which could be linked to 491 ICF categories: 222 (45.21%) of the categories referred to Body Functions, 29 (5.91%) to Body Structures, 186 (37.88%) to Activities and Participation and 54 (11%) to Environmental Factors. Seventy second-level categories were reported in at least 5% of all studies: 30 of these categories referred to Body Functions, 2 to Body Structures, 34 to Activities and Participation and 4 to Environmental Factors.

CONCLUSION

The study has allowed us to identify and quantify the main concepts included in studies focusing on people with schizophrenia using the ICF. The majority of the concepts refer to Body Functions and Activities and Participation, rather than to Body Structures and Environmental Factors.

Health professionals identify components of the International Classification of Functioning, Disability and Health (ICF) in questionnaires for the upper limb

BACKGROUND:

Several Brazilian studies have addressed the International Classification of Functioning, Disability and Health (ICF), but few have analyzed the knowledge of the health professionals with regards to the ICF.

OBJECTIVE:

To verify whether the classification of the items in the Brazilian-Portuguese versions of The Shoulder Pain and Disability Index (SPADI) and The Disabilities Arm, Shoulder and Hand (DASH) questionnaires, obtained from health professionals who worked with patients having upper limb injuries, could be related to ICF components as defined by others studies.

METHOD:

There were 4 participants for the group "professionals with high familiarity of the ICF (PHF)" and 19 for the group of "professionals with some or no familiarity of the ICF (PSNF)". The participants judged whether the items on the two questionnaires belonged to the ICF body function, body structure or activity-participation component, and marked a confidence level for each trial using a numerical scale ranging from zero to 10. The items were classified by the discriminant content validity method using the Student'st-test and the Hochberg correction. The ratings were compared to the literature by the percentage of agreement and Kappa coefficient.

RESULTS:

The percentage of agreement of the rating from the PSNF and the PHF groups with the literature was equal to or greater than 77%. For the DASH, the agreement of the PSNF and PHF groups with the literature were, respectively, moderate (Kappa=0.46 to 0.48) and substantial (Kappa=0.62 to 0.70).

CONCLUSIONS:

Health professionals were able to correlate the three components of the ICF for most items on the 2 questionnaires, demonstrating some ease of understanding the ICF components. However, the relation of concept of pain with body function component is not clear for professional and deserves a more attentive approach.

Effectiveness of a structured circuit class therapy model in stroke rehabilitation: a protocol for a randomised controlled trial

BACKGROUND

Currently, the key advocacy in neuroscientific studies for stroke rehabilitation is that therapy should be directed towards task specificity performed with multiple repetitions. Circuit Class Therapy (CCT) is well suited to accomplish multiple task-specific activities. However, while repetitive task practice is achievable with circuit class therapy, in stroke survivors repetitive activities may be affected by poor neurologic inputs to motor units, resulting in decreases in discharging rates which consequently may reduce the efficiency of muscular contraction. To accomplish multiple repetitions, stroke survivors may require augmented duration of practice. To date, no study has examined the effect of augmented duration of CCT in stroke rehabilitation, and specifically what duration of CCT is more effective in influencing functional capacity among stroke survivors.

METHODS/DESIGN

Using a randomised controlled trial with blinded outcome assessment, this study is aimed at determining the effectiveness of structured augmented CCT in stroke rehabilitation. Sixty-eight stroke survivors (to be recruited from a tertiary health institution in Kano, Northwest, Nigeria) will be randomised into one of four groups: three intervention groups of differing CCT durations namely: 60 min, 90 min, and 120 minuntes respectively, and a control group. Participants will take part in an 8-week structured intensive CCT intervention. Participants will be assessed at baseline, post-intervention, and six-month follow-up for the effectiveness of the varied durations of therapy, using standardised tools. Based on the WHO-ICF model, the outcomes are body structure/function, activity limitation, and participation restriction measures.

DISCUSSION

It is expected that the outcome of this study will clarify whether increasing CCT duration leads to better recovery of motor function in stroke survivors.

Evaluation of post-stroke functionality based on the International Classification of Functioning, Disability, and Health: a proposal for use of assessment tools

This study aimed to identify the International Classification of Functioning, Disability, and Health categories addressed by the assessment tools commonly used in post-stroke rehabilitation and characterize patients based on its evaluation model. [Subjects and Methods] An exploratory, descriptive, cross-sectional study was conducted involving 35 individuals with chronic post-stroke hemiparesis. Handgrip strength was assessed to evaluate body functions and structures. The 10-meter gait speed test and Timed Up and Go test were administered to evaluate activity. The Stroke Specific Quality of Life scale was used to evaluate participation. Moreover, a systematic review of the literature was performed to identify studies that have associated these assessment tools with the International Classification of Functioning, Disability, and Health categories. [Results] The tools employed in this study for evaluating function addressed 63 International Classification of Functioning, Disability, and Health categories: 24 related to body functions and structures; 36 related to activity and participation; and 3 related to environmental factors. [Conclusion] The assessment tools employed in this study addressed 63 International Classification of Functioning, Disability, and Health categories and allowed a more complete evaluation of stroke survivors with hemiparesis. Use of this classification can therefore be more easily incorporated into clinical practice.

Determinants of change in stroke-specific quality of life after distributed constraint-induced therapy

OBJECTIVE

We identified the predictive factors of change in quality of life (QOL) after a distributed form of constraint-induced therapy (dCIT) among stroke survivors.

METHOD

Seventy-four participants were treated with dCIT. We identified eight potential determinants of change: age, gender, side of lesion, time since stroke, cognitive status, motor impairment of the upper extremity, activities of daily living (ADLs), and instrumental ADLs (IADLs). The Stroke-Specific Quality of Life Scale (SS-QOL) was used to assess QOL.

RESULTS

Right-sided lesion and onset >17 mo earlier determined greater improvement in the SS-QOL Energy domain. Onset >10 mo earlier, poorer IADL performance, and age >68 yr predicted improvement in the Family Role, Mobility, and Mood domains, respectively.

CONCLUSION

Side of lesion, time since stroke, IADL performance, and age were the most important determinants of QOL in patients receiving stroke motor rehabilitation.

Determining quality of life in stroke survivors

Post-stroke health-related quality of life (HRQoL) reflects a comprehensive view of subjective health and a measure of a person's perceived physical, mental and social health following stroke. Generic scales may enable comparisons between groups of patients with a diverse range of conditions, although they may underestimate the effect of stroke owing to its limited content validity. Stroke-specific HRQoL measures were designed to assess relevant domains that are important to stroke patients. The Stroke Impact Scale, the Stroke Specific Quality of Life scale and The Burden of Stroke Scale are specific HRQoL instruments developed in the last decade. Demographic factors, comorbidity, stroke severity, disability and psychosocial factors (e.g., post-stroke depression and social support) are significant predictors of HRQoL in stroke survivors. Stroke caregiver burden and HRQoL are inversely correlated. HRQoL measures are increasingly used to evaluate the effect of some therapeutic interventions in stroke survivors.

Inspiratory muscular training in chronic stroke survivors: a randomized controlled trial

OBJECTIVE

To assess the effectiveness of inspiratory muscular training (IMT) on measures of strength, resistance, functional performance, and quality of life (QOL) for chronic stroke survivors.

DESIGN

Double-blinded randomized controlled trial.

SETTING

Research laboratory.

PARTICIPANTS

Subjects (N=21) with stroke (11 men, 10 women; maximal inspiratory pressure [MIP] <90% of predicted values) were randomly assigned to the experimental (n=11) and control groups (n=10); 18 participants completed all testing and training.

INTERVENTIONS

Interventions were based on home-based training, with resistance adjusted biweekly to 30% of MIP for the experimental group. The control group underwent the same protocol without the threshold resistance valve. Both groups received home training 30 minutes a day 5 times a week for 8 weeks.

MAIN OUTCOME MEASURES

MIP, inspiratory muscular endurance (IME), functional performance, and QOL.

RESULTS

There were significant between-group differences for the MIP and IME measures. Significant changes were observed for only the experimental group for MIP (67.8±14.6 at baseline to 102.2±26.0cmH(2)O at posttraining) and IME (31.8±19.3 to 49.2±21.1cmH(2)O). No statistically significant differences were observed for measures of functional performance and QOL.

CONCLUSIONS

Significant short-term effects of the IMT program for inspiratory strength and endurance were observed in chronic stroke survivors. These findings gave some indications that IMT may benefit people with stroke, and it is feasible to be included in rehabilitation interventions with this population.

Assessing the stroke-specific quality of life for outcome measurement in stroke rehabilitation: minimal detectable change and clinically important difference

Background

This study was conducted to establish the minimal detectable change (MDC) and clinically important differences (CIDs) of the physical category of the Stroke-Specific Quality of Life Scale in patients with stroke.

Methods

MDC and CIDs scores were calculated from the data of 74 participants enrolled in randomized controlled trials investigating the effects of two rehabilitation programs in patients with stroke. These participants received treatments for 3 weeks and underwent clinical assessment before and after treatment. To obtain test-retest reliability for calculating MDC, another 25 patients with chronic stroke were recruited. The MDC was calculated from the standard error of measurement (SEM) to indicate a real change with 95% confidence for individual patients (MDC₉₅). Distribution-based and anchor-based methods were adopted to triangulate the ranges of minimal CIDs. The percentage of scale width was calculated by dividing the MDC and CIDs by the total score range of each physical category. The percentage of patients exceeding MDC₉₅ and minimal CIDs was also reported.

Results

The MDC₉₅ of the mobility, self-care, and upper extremity (UE) function subscales were 5.9, 4.0, and 5.3 respectively. The minimal CID ranges for these 3 subscales were 1.5 to 2.4, 1.2 to 1.9, and 1.2 to 1.8. The percentage of patients exceeding MDC₉₅ and minimal CIDs of the mobility, self-care, and UE function subscales were 9.5% to 28.4%, 6.8% to 28.4%, and 12.2% to 33.8%, respectively.

Conclusions

The change score of an individual patient has to reach 5.9, 4.0, and 5.3 on the 3 subscales to indicate a true change. The mean change scores of a group of patients with stroke on these subscales should reach the lower bound of CID ranges of 1.5 (6.3% scale width), 1.2 (6.0% scale width), and 1.2 (6.0% scale width) to be regarded as clinically important change. This information may facilitate interpretations of patient-reported outcomes after stroke rehabilitation. Future research is warranted to validate these findings.

Systematic literature review on ICF from 2001 to 2009: its use, implementation and operationalisation

PURPOSE

To present a systematic literature review on the state of the art of the utilisation of the International Classification of Functioning, Disability and Health (ICF) since its release in 2001.

METHOD

The search was conducted through EMBASE, MEDLINE and PsychInfo covering the period between 2001 and December 2009. Papers were included if ICF was mentioned in title or abstract. Papers focussing on the ICF-CY and clinical research on children and youth only were excluded. Papers were assigned to six different groups covering the wide scenario of ICF application.

RESULTS

A total of 672 papers, coming from 34 countries and 211 different journals, were included in the analysis. The majority of publications (30.8%) were conceptual papers or papers reporting clinical and rehabilitation studies (25.9%). One-third of the papers were published in 2008 and 2009.

CONCLUSIONS

The ICF contributed to the development of research on functioning and on disability in clinical, rehabilitation as well as in several other contexts, such as disability eligibility and employment. Diffusion of ICF research and use in a great variety of fields and scientific journals is a proof that a cultural change and a new conceptualisation of functioning and disability is happening.

Uncovering indicators of the international classification of functioning, disability, and health from the 39-item Parkinson's disease questionnaire

The 39-item Parkinson's disease questionnaire (PDQ-39) is the most widely used patient-reported rating scale in Parkinson's disease (PD). However, recent studies have questioned its validity and it is unclear what scores represent. This study explored the possibility of regrouping PDQ-39 items into scales representing the International Classification of Functioning, Disability, and Health (ICF) components of Body Functions and Structures (BF), Activities and Participation (AP), and Environmental (E) factors. An iterative process using Rasch analysis produced five new items sets, two each for the BF and AP components and one representing E. Four of these were found to represent clinically meaningful variables: Emotional Impairment (BF), Gross Motor Disability (AP), Fine Motor Disability (AP), and Socioattitudinal Environment (E) with acceptable reliability (0.73-0.96) and fit to the Rasch model (total item-trait chi-square, 8.28-33.2; P > .05). These new ICF-based scales offer a means to reanalyze PDQ-39 data from an ICF perspective and to study its health components using a widely available health status questionnaire for people with PD.
