Pain is Common in Myositis and Associated with Disease Activity.

BACKGROUND: Understanding pain in myositis remains challenging. This study aimed to assess patient-reported pain and its correlation with myositis core set measures (CSMs), patient-reported outcomes (PROs), and functional measures. METHODS: Fifty subjects underwent baseline, 3-month, and 6-month assessments, evaluating myositis CSMs, functional measures, and patient-reported outcomes. Pain was measured using three methods: (1) a 10-cm Visual Analogue Scale (VAS), (2) pain score from the HAQ-DI, and (3) SF-36 (Short Form survey) pain questions. Correlations between disease activity measures and pain were examined at baseline, and changes in both were assessed at 6 months, along with longitudinal change of pain. The change in pain was also correlated with the published 2016 ACR/EULAR myositis response criteria, physician/patient's assessment of change. RESULTS: Nearly half of patients (45%) reported moderate to severe pain in all 3 pain scales, with higher severity of pain in PM/NM subset. At baseline, pain severity showed a strong correlation with most CSMs, PROs and functional outcomes in all the 3 pain scales and similar trends were noted for change in pain at the 6 months. On longitudinal analysis, the physical function scores and fatigue showed strong correlation with pain. Pain improved in myositis patients with improvement in disease activity over time. CONCLUSIONS: Pain is common in myositis and is associated with multiple measures of disease activity, PROs, and functional outcomes in myositis. Most importantly pain improves with improvement in disease activity. SF-36 pain questions have good psychometric properties.

The first step in developing an International Classification of Functioning, Disability and Health Core Set for Vision Loss: A systematic review.

AIM: As a first step in developing an International Classification of Functioning, Disability and Health (ICF) Core Set for adults with vision loss, this systematic review sought to identify the researchers' perspective by identifying the most often used outcome measures and research topics obtained from studies on adults with vision loss. METHODS: PubMed, Embase, CINAHL, APA PsycINFO and Web of Science were searched for studies on vision loss. Meaningful outcome measures and research topics were linked to the ICF components: environmental factors, body functions, body structures and the Activities and Participation life domains. RESULTS: After deduplication, 7219 records remained, of which 2328 articles were eligible for further review. For feasibility reasons, approximately 20% were randomly chosen from every publication year, resulting in 446 included articles. After full-text reading, 349 articles remained, describing 753 outcome measures based on questionnaires and 2771 additional research topics that could be linked to the ICF. Most were linked to the component Activities and Participation, with a focus on recreation and leisure activities (ICF code d920, 70%), reading (d166, 34%) and driving (d475, 27%). For the component body function, seeing functions (b210, 83%) were most often reported. Outcome measures and research topics were least often linked to the body structure component and environmental factors. CONCLUSION: The broad range of ICF categories identified in this systematic review represents the variety of functioning typical for adults with vision loss. These results reflect the focus of researchers over the past 21 years by using various vision-related outcomes. In our next steps to develop the ICF Core Set for Vision Loss, we will include perspectives of experts and lived experience.

Development of a brief core set for knee dysfunction based on the International Classification of Functioning, Disability and Health: assessing construct validity and measurement potential.

BACKGROUND: The comprehensive core set for knee dysfunction was developed to classify the functioning of people with any knee dysfunction. To be used as a clinical instrument to measure the functioning of people with knee dysfunction, the construct validity of the core set still needs to be assessed. The purpose of this study was to analyze the construct validity of the comprehensive core set for knee dysfunction as an instrument to measure functioning. METHODS: A cross-sectional study with 200 participants with knee dysfunction with or without clinical diagnosis of knee pathology, with or without complaint of pain, with or without instability, and/or with or without knee movement restriction of any type. Participants were assessed using the comprehensive core set for knee dysfunction with 25 categories, the subjective form from the International Knee Documentation Committee scale, and measures of self-perceived general health and functioning. The construct validity of the core set was assessed by Rasch analysis, and the external construct validity was assessed by correlation between the score of the brief core set for knee dysfunction with the subjective form from the International Knee Documentation Committee scale, and scores of self-perception of health and functioning. RESULTS: Twelve categories were consistent with a unidimensional construct, with no difference in the response pattern for age, sex, educational level, and time of complaint. These categories were included in the brief core set for knee dysfunction. The mean score of the brief core set was 37 ± 21 points, a value classified as moderate impairment regarding functioning. Correlations with the subjective form from the International Knee Documentation Committee scale and scores of self-perception were adequate (p < 0.01; r > 0.5). CONCLUSION: The brief core set for knee dysfunction, a set with 12 categories, can be used as a clinical instrument to measure and score the functioning of people with knee dysfunction, aged between 18 and 89 years, with adequate construct validity.

Limitations in functioning in climacteric syndrome: a systematic literature review using the ICF.

INTRODUCTION: This study is the first of four preparatory studies in the process to develop an International Classification of Functioning, Disability and Health (ICF) Core Set for climacteric syndrome. The aim was to identify perimenopausal and postmenopausal limitations in functioning reported in the scientific literature. METHODS: A systematic literature review was performed on MEDLINE, PsycInfo, Embase and CINAHL including publications from 2010 to 2020. Meaningful concepts were identified from the included studies and linked to the ICF using standardized linking rules. RESULTS: From the 6935 unique publications found, 300 articles were randomly selected for abstract screening and 48 studies met the inclusion criteria. From these, 1836 meaningful concepts were identified and linked to 158 different ICF categories. Most of them could be linked to the ICF chapter 'Body Functions'. Emotional, sleep, energy and drive as well as thermoregulatory functions and sensation of pain were addressed in >80% of all publications. CONCLUSION: Climacteric syndrome involves all four components of the ICF, but the focus of scientific research lies on limitations in body functioning. Limitations in body structures, activities and participation and environmental factors were less frequently assessed. The ICF is a valuable tool to describe the multidimensional phenotype of climacteric syndrome.

The Effect of ICF-Core Set-Based Occupational Therapy Interventions on the Function and Satisfaction of Individuals with Chronic Stroke: A Randomized Clinical Trial.

Stroke can affect all aspects of a person's health and functioning. Therefore, it is important occupational therapists, have a comprehensive understanding of various levels of function and the factors affecting function. The ICF (International Classification of Functioning, Disability, and Health) and the selections of ICF categories or Core Sets relevant for people with a specific health condition, offer a model for intervention. This study aimed to investigate the effect of ICF-CS-based occupational therapy interventions on the function and satisfaction of individuals with chronic stroke. This study was designed as a randomized, single-blind, parallel-group clinical trial. Twenty-five patients with stroke were randomly assigned to the control group (which received traditional occupational therapy) or the treatment group (Stroke ICF-CS based occupational therapy). Patients were evaluated before and after the intervention (two months, three sessions per week, 45 minutes each session), as well as two weeks after the end of the intervention, using Fugl-Meyer and COPM (Canadian Occupational Performance Measure) tools. The independent T-test, Chi-square, and ANOVA with repeated measures were used to analyze the data. The results showed that the interaction effect of time and group was not significant in none of the Fugl-Meyer test sections (p > 0. 05), but it was significant in the performance and satisfaction of COPM (p < 0.05). The results suggest that ICF-CS-based occupational therapy interventions may assist persons with chronic stroke improve their functional level and satisfaction.

Outcome Scores in Pediatric Rheumatology.

PURPOSE OF REVIEW: Providing a summary of the latest research on outcome measures in juvenile idiopathic arthritis, childhood -onset systemic lupus erythematosus, and juvenile dermatomyositis. RECENT FINDINGS: A rational management of patients with pediatric rheumatic diseases requires the regular assessment of the level of disease activity and damage, as well as the evaluation of therapeutic response through validated and standardized outcome measures. Ideally, such tools should be simple, feasible, and easily applicable in routine care. Recently, there has been a great deal of effort to refine existing tools and devise novel outcome measures, aiming to address the various aspects of disease impact and to improve the reliability of research studies and clinical trials. The newest outcome tools in pediatric rheumatology have markedly enlarged the spectrum of health domains assessable in a standardized way, thus increasing the reliability of evaluation of clinical response and fostering future clinical trials.

Long-term outcomes after critical illness: recent insights.

Intensive care survivors often experience post-intensive care sequelae, which are frequently gathered together under the term "post-intensive care syndrome" (PICS). The consequences of PICS on quality of life, health-related costs and hospital readmissions are real public health problems. In the present Viewpoint, we summarize current knowledge and gaps in our understanding of PICS and approaches to management.

Validation of the Brief International Classification of Functioning, Disability and Health (ICF) core set for hearing loss: an international multicentre study.

OBJECTIVE: Hearing loss (HL) affects the everyday functioning of millions of people worldwide. The Brief International Classification of Functioning Disability and Health (ICF) core sets for HL was developed to meet the complex health care needs of adults with HL. Because the brief core set for HL has not yet been validated internationally, this study aimed to investigate its validity from an international perspective. DESIGN: A cross-sectional validation study based on data from structured interviews with adults with HL. STUDY SAMPLE: Participants (n = 571) from India, South Africa, Sweden and the US were included. RESULTS: A six-factor solution explained 71% of the variance, focussing on issues related to communication, the social environment, participation in society, health care services, support, relationships and emotions (α = 0.915). Three ICF categories demonstrated low reliability - temperament and personality functions, seeing functions and school education. CONCLUSION: The Brief ICF core set for HL is valid for adults with HL internationally. However, to further increase its international validity, we recommend adding the categories d920 recreation and leisure and replacing d850 school education with the more inclusive block, d810-d839 education.

Laying the foundation for an ICF core set for community dwelling older adults in primary care: an expert survey.

BACKGROUND: A holistic biopsychosocial model focused on functioning in individual contexts (environment, task) is better suited to meet the needs of older patients than disease only based models. The International Classification of Functioning, Disability and Health (ICF) is the official standard for describing functional health. As the ICF is too detailed to be used in practice, brief core sets have been developed. OBJECTIVE: This study aimed to identify relevant aspects of functioning for older primary care patients from the perspective of healthcare professionals in Germany. MATERIAL AND METHODS: An internet-based cross-sectional expert survey was conducted in preparation for the development of an ICF core set for community-dwelling patients aged 75 years and older. Open-ended questions to identify the most important aspects of functioning and disability in old age were used. Responses were analyzed based on a content analysis approach to identify relevant concepts in the care of the target population. These concepts were then linked to ICF categories according to established linking rules. RESULTS: A total of 63 experts participated in this survey. Across all responses, 2240 meaningful concepts were identified. A total of 75 ICF categories (4 first level categories, 67 second level categories, 4 code combinations) were identified by at least 5% of respondents and will thus be considered as candidate categories for the final ICF core set. Most of concepts were associated with the environmental factors component. The most frequently identified categories were immediate family and family relationships. CONCLUSION: This survey provides a list of relevant ICF categories from the experts' perspective and together with other preparatory studies will be used for developing an ICF core set for community-dwelling older adults in primary care.

Performance of brief ICF-sleep disorders and obesity core set in obstructive sleep apnea patients.

BACKGROUND: Clinical questionnaires are mainly applied as screening tools for identification of the Obstructive sleep apnea (OSA) patients. Little attention has been paid to assess the body functions and health status of the patients. International Classification of Functioning, Disability and Health (ICF) was designed for better understanding and describing functioning and disability of patients. This study adopted the Brief ICF-Sleep Disorders and Obesity Core Set to evaluate the impairment of functioning and health status of OSA patients. METHODS: Five hundred ninety-two participants were enrolled in this cross-sectional study. Data were collected using Brief ICF-Sleep Disorders and Obesity Core Set Polysomnography was performed and basic characteristics of the patients were recorded. RESULTS: The scores for the component Body Functions and Code b130, b134, b140, b440, b530, s330, d160, d240, d450 of the two core sets were significantly different among the patients divided by apnea-hypopnea index (AHI) or oxygen saturation (SaO2) nadir, but the frequency of code s330, d160, d240, d450 was low. The Body Functions component of the both sets were closely related to neck circumference (NC), body mass index (BMI), apnea-hypopnea index (AHI) of the OSA patients. Body Functions of the Brief ICF-Sleep Disorders performed better with a threshold of 4 with sensitivity, specificity and area under the receiver operating characteristic curve (AUC) as 0.62, 0.74, 0.68(AHI ≥ 5), 0.69, 0.63, 0.66 (AHI ≥ 15), 0.75, 0.56, 0.66 (AHI ≥ 30), 0.56, 0.70, 0.63 (SaO2 nadir≤90%), 0.67, 0.66, 0.66 (SaO2 nadir<85%), 0.71, 0.59, 0.65 (SaO2 nadir<80%), separately. CONCLUSION: The Body Functions component of both two sets could be an evaluation tool of impairment of body functions for OSA patients. The Brief ICF-Sleep Disorders Body Functions component performed better with a threshold of 4 and might provide a new insight for physicians to assess OSA patients.

Construction of an ICF core set and ICF-based questionnaire assessing activities and participation in patients with systemic sclerosis.

OBJECTIVES: To develop an International Classification of Functioning, Disability and Health (ICF) core set for SSc and to conceive a patient-centred ICF-based questionnaire assessing activities and participation in patients with SSc. METHODS: The construction of the ICF core set followed two steps. In the first step, meaningful concepts related to SSc were collected using data source triangulation from patients (n = 18), experts (n = 10) and literature (n = 174 articles). In the second step, concepts were linked to the best-matching ICF categories by one reviewer according to prespecified linking rules. Finally, patient-reported activities and participation categories of the ICF core set were translated into understandable questions. RESULTS: After linking concepts to ICF categories, 150 ICF categories were collected from focus groups, 22 from experts and 82 from literature. After fusion of the sources and removal of duplicates, the ICF core set included 164 categories: one at the first level, 157 at the second level and six at the third level, with 50 categories on body functions, 15 on body structures, 52 on activities and participation, and 47 on environmental factors. Patient-reported ICF categories on activities and participation were translated into a patient-centred ICF-based 65-item questionnaire. CONCLUSION: The present study proposes an ICF core set that offers a conceptual framework for SSc patients' care and health policy. Using a patient-centred approach, a patient-centred ICF-based questionnaire, the Cochin Scleroderma ICF-65 questionnaire, assessing activities and participation in patients with SSc, was conceived. TRIAL REGISTRATION: ClinicalTrials.gov, http://clinicaltrials.gov, NCT01848418.

Validation of the brief international classification of functioning, disability, and health core set for obstructive pulmonary disease in the Chinese context.

In order to determine the validity of the International Classification of Functioning, Disability, and Health brief Core Set for Obstructive Pulmonary Disease (ICF-OPD) for the assessment of functioning and environmental factors in Chinese chronic OPD (COPD) patients, we conducted a cross-sectional study with a convenience sample of 100 COPD patients. Data were collected using common questionnaires for COPD patients (Modified British Medical Research Council Questionnaire, COPD Assessment Test, St George's Respiratory Questionnaire (SGRQ)), the Brief ICF Core Set for OPD, and the comprehensive ICF checklist. All except one category of the Brief ICF-OPD Core Set were confirmed in our evaluation of its content validity, but there is a high prevalence of problems in 8 categories that were not considered in the Brief ICF-OPD Core Set. The functioning-related components of the Brief ICF-OPD Core Set largely performed similarly to SGRQ in terms of differentiating between patients with different disease severity. Moreover, high correlations between the Brief ICF-OPD Core Set overall score and component scores with the respective SGRQ scales and moderate correlations between ICF-OPD Core Set overall score and component scores and lung function parameters. This study largely confirmed content, known group, and convergent validity of the ICF-OPD.

Genetic diversity and structure of core collection of winter mushroom (Flammulina velutipes) developed by genomic SSR markers.

BACKGROUND: A core collection is a subset of an entire collection that represents as much of the genetic diversity of the entire collection as possible. The establishment of a core collection for crops is practical for efficient management and use of germplasm. However, the establishment of a core collection of mushrooms is still in its infancy, and no established core collection of the economically important species Flammulina velutipes has been reported. RESULTS: We established the first core collection of F. velutipes, containing 32 strains based on 81 genetically different F. veltuipes strains. The allele retention proportion of the core collection for the entire collection was 100%. Moreover, the genetic diversity parameters (the effective number of alleles, Nei's expected heterozygosity, the number of observed heterozygosity, and Shannon's information index) of the core collection showed no significant differences from the entire collection (p > 0.01). Thus, the core collection is representative of the genetic diversity of the entire collection. Genetic structure analyses of the core collection revealed that the 32 strains could be clustered into 6 groups, among which groups 1 to 3 were cultivars and groups 4 to 6 were wild strains. The wild strains from different locations harbor their own specific alleles, and were clustered stringently in accordance with their geographic origins. Genetic diversity analyses of the core collection revealed that the wild strains possessed greater genetic diversity than the cultivars. CONCLUSION: We established the first core collection of F. velutipes in China, which is an important platform for efficient breeding of this mushroom in the future. In addition, the wild strains in the core collection possess favorable agronomic characters and produce unique bioactive compounds, adding value to the platform. More attention should be paid to wild strains in further strain breeding.

Content and Face Validity and Feasibility of 5 Candidate Instruments for Psoriatic Arthritis Randomized Controlled Trials: The PsA OMERACT Core Set Workshop at the GRAPPA 2017 Annual Meeting.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA)-Outcome Measures in Rheumatology (OMERACT) Psoriatic Arthritis (PsA) Core Set working group is in the process of selecting core instruments for PsA clinical trials. During a 2-h workshop and breakout group discussions at the GRAPPA 2017 annual meeting in Amsterdam, the Netherlands, participants discussed the first set of candidate instruments to be taken through the OMERACT Filter 2.1 instrument selection process: 66/68 swollen/tender joint count (66/68JC), Spondyloarthritis Consortium of Canada (SPARCC) enthesitis index, patient's global assessment (GRAPPA and OMERACT formulations), Health Assessment Questionnaire-Disability Index (HAQ-DI), Psoriatic Arthritis Impact of Disease (PsAID) questionnaires 9 and 12, and Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue. Based on the assessment of domain match (content and face validity) and feasibility according to the OMERACT instrument selection criteria, the working group recommends continuing with appraisal of construct validity and discrimination for 66/68JC, SPARCC, PsAID 9 and 12, HAQ-DI, and FACIT-Fatigue. In addition, it recommends repeating the OMERACT Filter 2.1 process for patient global instruments because of insufficient votes. Additional sets of candidate instruments for the PsA core instrument set will be evaluated in a similar process.

Relationship between geographical origin, seed size and genetic diversity in faba bean (Vicia faba L.) as revealed by SSR markers.

Faba bean (Vicia faba L.) is an important legume species because of its high protein and starch content. Broad bean can be grown in different climatic conditions and is an ideal rotation crop because of the nitrogen fixing bacteria in its roots. In this work, 255 faba bean germplasm accessions were characterized using 32 SSR primers which yielded 302 polymorphic fragments. According to the results, faba bean individuals were divided into two main groups based on the neighbor-joining algorithm (r = 0.91) with some clustering based on geographical origin as well as seed size. Population structure was also determined and agreed with the dendrogram analysis in splitting the accessions into two subpopulations. Analysis of molecular variance (AMOVA) revealed high levels of within population genetic variation. Genetic similarity and geographical proximity were related with separation of European accessions from African and Asian ones. Interestingly, there was no significant difference between landrace (38%) and cultivar (40%) diversity indicating that genetic variability has not yet been lost due to breeding. A total of 44 genetically well-characterized faba bean individuals were selected for a core collection to be further examined for yield and nutritional traits.

The "Comprehensive ICF Core Set for Head and Neck Cancer": a Delphi consensus survey among German speaking speech and language therapists.

The "Comprehensive ICF Core Set for Head and Neck Cancer" (ICF-HNC) is an application of the "International Classification of Functioning, Disability and Health" (ICF), representing the characteristic spectrum of issues in patients with head and neck cancer (HNC). Our primary aim was to evaluate which categories of the ICF-HNC are dealt with by speech and language therapists (SLTs) in Germany, Austria, and Switzerland. The secondary aim was to identify outcome measures used by SLTs to measure the categories of the ICF-HNC in clinical practice. SLTs experienced in the treatment of HNC patients evaluated the categories of the ICF-HNC in a three-round Delphi survey. They were asked whether the listed categories represented issues treated by SLTs in HNC patients, and what outcome measures were used to assess them. Altogether, 31 SLTs completed the survey. 47 of 108 previously selected categories of the ICF-HNC achieved the cut-off value. Out of these, 40.4% were derived from the component "Body Functions", 36.2% from "Body Structures", 12.8% from "Environmental Factors", and 10.6% from "Activities and Participation". Altogether, 82 of the mentioned outcome measures were considered as reasonable from the perspective of SLTs. Of these, only 37 achieved more than 50% approval. This study emphasises the importance of "Body Structures" and "Body Functions" for SLTs in Germany and Switzerland in treating patients with HNC. Moreover, the results highlighted the need to agree on evidence-based outcome measures in speech and language therapy.

Identification of physical and psychosocial problems associated with diabetic nephropathy using the International Classification of Functioning, Disability and Health Core Set for Diabetes Mellitus.

BACKGROUND: We previously demonstrated validation of the Comprehensive International Classification of Functioning, Disability and Health Core Set for Diabetes Mellitus (ICF-CS for DM) in patients with diabetic nephropathy (DMN). The objective of the present study was to identify differences in experience of physical and psychosocial problems between DMN patients with and without hemodialysis (HD), and diabetes patients without nephropathy using the ICF-CS for DM. METHODS: A total of 302 diabetes outpatients (men, 68 %; mean age, 62 years) were interviewed using four components of the ICF-CS for DM including "Body functions", "Body structures", "Activities and participation", and "Environmental factors". RESULTS: The mean number of categories in which difficulty was experienced in the four components was significantly greater in DMN patients with HD followed by DMN patients without HD, and diabetes patients without nephropathy (23.9 vs. 18.0 vs. 13.1, respectively). Multivariate logistic regression models revealed that, compared with diabetes patients without nephropathy, diabetes patients with nephropathy were more likely to have difficulty with physical problems and social activities and participation. Among DMN patients, dialysis patients were found to have larger numbers of problems, and face difficulty with employment status after adjusting for sex, age, type, and duration of diabetes. CONCLUSION: The results of this study using the ICF-CS for DM identified the areas for improvement among physical and psychosocial problems in DMN patients with and without HD in contrast to diabetes patients without nephropathy.

Clinical characteristics of cutaneous lupus erythematosus.

INTRODUCTION: Lupus erythematosus (LE) shows a wide variety of clinical manifestations, skin involvement being one of the most important. AIM: To analyze the clinical presentation of cutaneous variants of lupus erythematosus in terms of skin lesion spectrum and extracutaneous involvement. MATERIAL AND METHODS: A total of 64 patients with cutaneous LE (CLE) were included. The study was based on the "Core Set Questionnaire" developed by the European Society of Cutaneous Lupus Erythematosus (EUSCLE). Clinical severity of skin lesions was evaluated with the Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI). All results were subjected to statistical analysis. RESULTS: Fifteen (23.4%) patients had an acute CLE (ACLE), 26 (40.6%) subacute CLE (SCLE) and 21 (32.8%) chronic CLE (CCLE). Two (3.2%) individuals only demonstrated urticarial vasculitis as a cutaneous manifestation of LE and these patients were excluded. Patients with ACLE were characterized by the earliest onset of the disease (mean age of 31.9 ±15.0 years; p < 0.001). On average, 4.8 ±1.8 criteria of systemic LE were found in the ACLE group compared to 2.7 ±1.3 criteria in SCLE and 2.5 ±1.5 criteria in CCLE (p < 0.001). The highest activity of skin lesions according to CLASI was found in the SCLE group (p = 0.002). On the other hand, the most severe skin damage was observed in CCLE (p < 0.01). CONCLUSIONS: Each variant of CLE differs significantly from the others in respect of various aspects of clinical manifestations. Due to a number of different variants of LE skin lesions, a unified classification of CLE still remains a challenge.

Functional performance in older adults with hearing loss: Application of the International Classification of Functioning brief core set for hearing loss: A pilot study.

OBJECTIVES: The beta version of the International Classification of Functioning, Disability, and Health (ICF) brief core set for hearing loss in adults was developed and recommended to be validated through the audiologic rehabilitation clinical practice. The aims of this pilot study were to validate the ICF brief core set by examining the dimensions of hearing performance measures used in a standard care university clinic specializing in amplification, and seeing if those dimensions support the structure provided by the core set. DESIGN: ICF linking, classification, and qualifier coding procedures were applied on a data set identified from clinical records and two paper-pencil questionnaires; and completed by consensus of two experienced audiologists. STUDY SAMPLE: Forty-nine participants were recruited from an out-patient population at an audiology clinic. RESULTS: Eighteen of 27 items from the brief core set were able to be linked and validated. Four factors were identified, and confirmed the structure of ICF concept: Auditory function, Other functions, Activities/contextual interaction, and Third-party disability. Further, three predictors significantly discriminated performance in 28 participants: the use of hearing assistive devices, speech-reading, and active social life. CONCLUSIONS: The ICF brief core set is a valuable tool for use in audiologic rehabilitation clinical practice and research design.

Global Functioning of COPD Patients With and Without Functional Balance Impairment: An Exploratory Analysis Based on the ICF Framework.

Balance impairment is a common manifestation in older people with COPD and may contribute to overall functional decline; however, the relationship between balance and global functioning has not been studied. This study aimed to explore the global functioning of COPD patients with and without functional balance impairment. Functional balance was assessed with the Timed Up-and-Go (TUG) test and global functioning with the Comprehensive ICF Core Set for Obstructive Pulmonary Diseases. Participants (n = 134) were divided in 2 groups according to their performance in TUG (with and without balance impairment) and the ICF Core Set results were compared between groups. Fifty-four (40.3%) participants had functional balance impairment. The groups presented a similar extent of problems in several categories of the ICF components. However, participants with balance impairment were more severely affected (p < 0.05) in energy, pain, respiratory system, weight maintenance, exercise tolerance, neuromusculoskeletal and movement-related functions, and structure of head and neck. They also presented a significantly worse performance in handling psychological demands and activities related to mobility, self-care, domestic, community and social life, and a more negative perception of Environmental factors related to products and technology of buildings for private use and social support services (p < 0.05). Patients with functional balance impairment have more functional problems and are more severely restricted in daily life than patients without compromised balance. Understanding the relationship between balance control and global functioning will contribute to guide interventions aimed at maintaining functioning and minimizing disability.
