ICF Core Sets for osteoporosis

The International Classification of Functioning, Disabilities, and Health categories rated as necessary for care planning for older patients with heart failure: a survey of care managers in Japan

BACKGROUND

Establishing an information-sharing system between medical professionals and welfare/care professionals may help prevent heart failure (HF) exacerbations in community-dwelling older adults. Therefore, we aimed to identify the ICF categories necessary for care managers to develop care plans for older patients with HF.

METHODS

A questionnaire was administered to 695 care managers in Hiroshima, Japan, on ICF items necessary for care planning. We compared the care managers according to their specialties (medical qualifications and welfare or care qualifications). Furthermore, we created a co-occurrence network using text mining, regarding the elements necessary for collaboration between medical and care professionals.

RESULTS

There were 520 valid responses (74.8%). Forty-nine ICF items, including 18 for body functions, one for body structure, 21 for activities and participation, and nine for environmental factors, were classified as "necessary" for making care plans for older people with HF. Medical professionals more frequently answered "necessary" than care professionals regarding the 11 items for body functions and structure and three items for activities and participation (p < 0.05). Medical-welfare/care collaboration requires (1) information sharing with related organisations; (2) emergency response; (3) a system of cooperation between medical care and non-medical care; (4) consultation and support for individuals and families with life concerns, (5) management of nutrition, exercise, blood pressure and other factors, (6) guidelines for consultation and hospitalisation when physical conditions worsen.

CONCLUSIONS

Our findings showed that 49 ICF categories were required by care managers for care planning, and there was a significant difference in perception between medical and welfare or care qualifications qualifications.

The Reliability and Validity of the Brief ICF Core Set in Patients with Chronic Obstructive Pulmonary Disease

Purpose

To analyze the reliability and validity of the Brief international classification of functioning, disability and health (ICF) core set for chronic obstructive pulmonary disease (COPD).

Patients and Methods

A cross-sectional study was conducted in four tertiary hospitals in Tianjin, China. A total of 100 patients with COPD were selected to evaluate functioning and disability involving body functions, body structures, activities and participation as well as environmental factors of the Brief ICF core set for COPD. Internal consistency was calculated by Cronbach's α. Content validity was examined using the content validity index (CVI), scale-level CVI/universal agreement, and scale-level CVI/average agreement (S-CVI/Ave). In addition, construct validity and convergent validity were also examined.

Results

The Brief ICF core set for COPD had a high internal consistency, 0.873 for the total scale, with values of 0.750, 0.640, and 0.843 for body functions, body structures, and activity and participation, respectively. The content validity was calculated by the CVI, scale-level CVI/universal agreement, and S-CVI/Ave at values of 0.80-1, 0.929, and 0.986, respectively. Meanwhile, the ICF core set for COPD had good convergent validity, correlating with the mMRC dyspnea score (r=0.690, P<0.01), and there were significant correlations between the ICF core set for COPD and COPD clinical severity grade (r=0.363, P<0.01). A four-factor model of functions and disability in the Brief ICF core set for COPD had the best fit according to confirmatory factor analysis (CFA).

Conclusion

The Brief ICF core set for COPD is a reliable and valid convenient instrument for assessing comprehensive problems in the functioning of patients with COPD, which can be used to design and to evaluate rehabilitation strategies.

Content Validation of a Practice-Based Work Capacity Assessment Instrument Using ICF Core Sets

PURPOSE

A shift from providing long-term disability benefits to promoting work reintegration of people with remaining work capacity in many countries requires new instruments for work capacity assessments. Recently, a practice-based instrument addressing biopsychosocial aspects of functioning, the Social Medical Work Capacity instrument (SMWC), was developed. Our aim was to examine the content validity of the SMWC using ICF core sets.

METHODS

First, we conducted a systematic search to identify relevant ICF core sets for the working age population. Second the content of these core sets were mapped to assess the relevance and comprehensiveness of the SMWC. Next, we compared the content of the SMWC with the ICF-core sets.

RESULTS

Two work-related core sets and 31 disease-specific core sets were identified. The SMWC and the two work-related core sets overlap on 47 categories. Compared to the work-related core sets, the Body Functions and Activities and Participation are well represented in the new instrument, while the component Environmental factors is under-represented. Compared to the disease-specific core sets, items related to the social and domestic environmental factors are under-represented, while the SMWC included work-related factors complementary to the ICF.

CONCLUSION

The SMWC content seems relevant, but could be more comprehensive for the purpose of individual work capacity assessments. To improve assessing relevant biopsychosocial aspects, it is recommended to extend the instrument by adding personal and environmental (work- and social-related) factors as well as a more tailored use of the SMWC for assessing work capacity of persons with specific diseases or underlying illness.

Health social workers' assessments as part of a specialized pain rehabilitation: a clinical data-mining study

This study examines how health social workers (HSWs) assess the rehabilitation needs of patients with long-term pain. Data were extracted from 66 patient assessments through a retrieval form based on the International Classification of Functioning, Disability, and Health. The assessments included information about relations, work, and recreation. Stress management, problem solving, self-care, participation in community life, and providing personal care were missing in parts of or all assessments. Differences in assessments suggest that information was registered based on traditional gender roles and age. Therefore, HSWs need standardized assessment tools to ensure that assessments are relevant for all patients with long-term pain irrespective of gender or age.

Application of ICF conceptual framework in Osteoporosis

Background: Osteoporosis (OP) is a metabolic bone disease defined by low bone strength and deterioration of bone tissue, which has wide clinical presentations. The World Health Organization's International Classification of Functioning Disability and Health (ICF) provides a common language, classification system, and conceptual framework to describe the consequences of health conditions in terms of body function and structure, activities and participation, environmental and personal factors. Objectives: The ICF conceptual framework was used, in this paper, to integrate OP research-based knowledge into clinical application using clinical vignettes. Results: Body functions and structures, activities and participation, environmental factors and personal factors are described, and the inter-connection among these factors is explored. The vignettes highlight the importance of different components of the ICF framework and to demonstrate how the ICF framework can capture individual differences in how disability can be experienced in OP. Conclusion: The ICF conceptual framework provides a holistic representation of disability by facilitating a critical appraisal of the health status of people with OP. The framework creates an awareness of the broad and multidimensional nature of OP on the health of individual patients, integrates dimensions of functioning, and highlights the complexity of the evaluation and management of OP.

Exercise to improve functional outcomes in persons with osteoporosis: a systematic review and meta-analysis

Osteoporosis affects many aspects of daily life. The aim of this systematic review was to assess the effects of exercise interventions on functional outcomes in persons with osteoporosis, in comparison with controls.

METHODS

Four databases were searched and yielded 1587 citations. Two reviewers independently determined study eligibility, rated risk of bias, appraised methodological quality of studies, and resolved discordance by consensus.

RESULTS

A total of 28 studies examining 2113 participants met inclusion criteria; 25 studies were suitable for meta-analyses. Four categories of exercise were identified using the ProFaNE taxonomy. After removing studies with high risk of bias and sorting them into intervention sub-types, we were able to sufficiently reduce the heterogeneity. The standardized mean difference (SMD) favored multicomponent exercise for mobility (- 0.56, 95% CI [- 0.81, - 0.32], p = 0.06, I² = 51%); balance (0.50, 95% CI [0.27, 0.74], p = 0.28, I² = 21%); and self-reported measures of functioning (- 0.69, 95% CI [- 1.04, - 0.34], p = 0.02, I² = 61%). Trials were judged at low or unclear risk of selection bias, indicating inadequate reporting and at high risk of performance bias due to lack of participant blinding. The mean methodological quality rating of the studies was 63.5% indicating moderate quality.

CONCLUSIONS

A multicomponent exercise program of high-speed training combined with simulated functional tasks is promising to enhance functional outcomes. Due to substantial clinical heterogeneity of the target groups and specific demands of exercise modes, it is unclear which exercise program is optimal.

Functioning of active postmenopausal women with osteoporosis

Abstract Introduction: The multiple aspects of disability in patients with osteoporosis require comprehensive tool for their assessment. The International Classification of Functioning, Disability and Health (ICF) is designed to describe the experience of such patients with theirs functioning. Objective: This study aimed to describe the functioning in a sample of active postmenopausal women with osteoporosis according to the brief ICF core set for osteoporosis. Methods: This cross-sectional study was conducted among active community-dwelling older adults in a southern Brazilian city. Participants were enrolled by convenience sampling from a group conducting supervised aquatic and land-based exercises. Active postmenopausal women with osteoporosis were included. Thirty-two women (mean age 68.0 ± 5.1 years old) participated in the evaluation. The brief ICF core set for osteoporosis was used to establish functional profiles. The categories were considered valid when ≥20% of participants showed some disability (according to ICF qualifiers). Results: No category showed a high level of disability, as >50% of women rated by qualifiers .3 or .4. Only the category e580 was considered by all participants as a facilitator. Conclusion: The brief ICF core set for osteoporosis results demonstrated that this classification system is representative to describe the functional profile of the sample. Active postmenopausal women with osteoporosis presented few impairments related to body functions and structures, activities and participation and environmental factors.

Development of ICF Core Sets to standardize assessment of functioning and impairment in ADHD: the path ahead

In the study of health and quality of life in attention deficit/hyperactivity disorder (ADHD), it is of paramount importance to include assessment of functioning. The International Classification of Functioning, Disability and Health (ICF) provides a comprehensive, universally accepted framework for the description of functioning in relation to health conditions. In this paper, the authors outline the process to develop ICF Core Sets for ADHD. ICF Core Sets are subgroups of ICF categories selected to capture the aspects of functioning that are most likely to be affected in specific disorders. The ICF categories that will be included in the ICF Core Sets for ADHD will be determined at an ICF Core Set Consensus Conference, wherein evidence from four preliminary studies (a systematic review, an expert survey, a patient and caregiver qualitative study, and a clinical cross-sectional study) will be integrated. Comprehensive and Brief ICF Core Sets for ADHD will be developed with the goal of providing useful standards for research and clinical practice, and to generate a common language for the description of functioning in ADHD in different areas of life and across the lifespan.

The burden of musculoskeletal conditions

Objective

Despite the burden of rheumatic and musculoskeletal diseases (RMDs), these conditions probably deserve more attention from public health authorities in several countries including developed ones. We assessed their contribution to disability.

Methods

Data on disabilities associated with RMDs were extracted from the national 2008–2009 Disability-Health Survey of 29,931 subjects representative of the population in France. We used the core set of disability categories for RMDs of the World Health Organization's International Classification of Functioning, Disability and Health for analysis. Diagnosis and disabilities were self-reported. We assessed the risk of disability associated with RMDs using odds ratios (ORs) and the societal impact of RMDs using the average attributable fraction (AAF).

Results

Overall 27.7% (about 17.3 million people) (95% CI 26.9–28.4%) of the population reported having RMDs. The most prevalent RMDs were low back pain (12.5%, 12.1–13.1) and osteoarthritis (12.3%, 11.8–12.7). People reporting osteoarthritis were more disabled in walking (adjusted OR 1.9, 1.7–2.2) than those without. People reporting inflammatory arthritis were more limited in activities of daily living (from 1.4, 1.2–1.8 for walking to 2.1, 1.5–2.9 for moving around). From a societal perspective, osteoarthritis was the main contributor to activity limitations (AAF 22% for walking difficulties). Changing jobs was mainly attributed to neck pain (AAF 13%) and low back pain (11.5%).

Conclusion

RMDs are highly prevalent and significantly affect activity limitations and participation restrictions. More effort is needed to improve care and research in this field.

Inclinometer-based measures of standing posture in older adults with low bone mass are reliable and associated with self-reported, but not performance-based, physical function

The association between posture and physical function during daily activities in people at risk for osteoporotic fracture is not clear. We report the reliability of measuring posture using the digital inclinometer and how these measures relate to performance-based and self-reported physical function.

INTRODUCTION

This study aims to determine the reliability of a simple clinical method for assessing spine curvatures in people with low bone mass and the association between spine curvature measures and pain, physical function (mobility/activities of daily living (ADL)) and quality of life.

METHODS

One rater assessed 36 high-functioning adults, aged 52-82 years, attending an outpatient osteoporosis clinic. A digital inclinometer was used to measure lumbosacral angle (S), lumbar standing posture (L), and thoracic standing posture (T) and ADL performance was assessed using the short form of the Safe Functional Motion test (SFM-6), on two occasions approximately 8.7 days apart. Participants reported average pain intensity over the past week and completed the Timed Up and Go test (TUGT) and the mini-Osteoporosis Quality of Life questionnaire (mini-OQLQ). Acceptable reliability was determined using the intraclass correlation coefficient (ICC). Associations were determined using Pearson's correlation coefficients (r) (and Spearman's rho (r s), for non-normal data).

RESULTS

ICC (95 % CI) for S, L, and T = 0.91 (0.82, 0.95), 0.90 (0.82, 0.95), and 0.91 (0.84, 0.95), respectively, for test-retest reliability. Thoracic standing posture was associated with the ADL domain of the mini-OQLQ (r s = -0.39) and the TUGT (r = 0.42). Standing posture was not related to pain or total SFM-6 score.

CONCLUSIONS

Digital inclinometer measures provide a quick highly reliable, valid, direct assessment of kyphosis. Use of these measures in the clinical setting is expected to facilitate identification and effective management of postural impairments (e.g., trunk extensor muscle weakness, vertebral fracture) associated with osteoporosis.

Post-surgical rehabilitative approach to fragility fractures

Osteoporosis is a skeletal disorder characterized by compromised bone strength predisposing to an increased risk of fracture. The most frequent sites of fragility fractures are the hip, the distal radius, the spine, the proximal humerus, and the ankle. In most cases, a surgical approach with subsequent rehabilitative treatment is required. The general aims of rehabilitation are to increase functioning and improve patients' activities, participation level, and quality of life.

Content comparison of self-reported disability measures for the elderly according to the international classification of functioning, disability and health

PURPOSE

To identify self-reported disability measures developed for older adults by performing a systematic literature review and to compare the contents of all identified measures based on the International Classification of Functioning, Disability and Health (ICF).

METHOD

A broad systematic literature search was performed in March 2012 in the following databases: MEDLINE, EMBASE, CINAHL, PsycINFO and PROQOLID. Each item in the identified measures was extracted and linked to the ICF categories. A content comparison between measures was performed. The content density and diversity of each measure were assessed by calculating the content density ratio (the number of meaningful concepts divided by the number of items in each questionnaire) and content diversity ratio (the number of different ICF categories divided by the number of linked meaningful concepts), respectively.

RESULTS

We reviewed 5622 published articles and identified 13 eligible measures. In total, 293 meaningful concepts from 265 items were extracted, of which, 270 concepts were linked to the ICF. A total of 62 different ICF categories were addressed. EARRS, FHS and SF-LLFDI had the highest content density ratio, while FHS and KI had the highest content diversity ratio. Different measures differed considerably in content.

CONCLUSIONS

The ICF can be used as a conceptual framework not only for assessing measures but also for developing new measures. According to this ICF-based content comparison, the contents of currently available measures for disability in older adults vary significantly from one another. Our study may provide useful information for the selection of suitable measures for a particular purpose, as well as the development of new measures.

The ability of outcome questionnaires to capture patient concerns following ankle reconstruction

BACKGROUND

The objective of this study was to compare questions from outcome questionnaires with items generated by preoperative and postoperative ankle reconstruction patients (using the open-ended questions of self-reported Patient-Specific Index [PASI]) to determine whether existing questionnaires address patients' concerns.

METHODS

Patients (n = 142) completed the PASI. Questions from 6 standardized questionnaires (American Academy of Orthopaedic Surgeons Foot and Ankle Questionnaire [AAOS], patient-reported portion of the American Orthopaedic Foot and Ankle Society Clinical Rating System Ankle-Hindfoot Scale [AOFAS], Foot Function Index [FFI], Lower Extremity Functional Scale [LEFS], Short Musculoskeletal Function Assessment [SMFA], Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]) and PASI were matched by 3 reviewers to corresponding categories in the International Classification of Functioning, Disability and Health (ICF). Standardized questionnaires were then compared with the patient responses produced by the PASI.

RESULTS

Patients identified 690 items corresponding to 45 ICF categories. Most PASI concepts fell into Activities and Participation (60.3%) and Body Functions (29.0%) components, including the categories "walking" (19.1%), "pain" (16.5%), and "recreation and leisure" (15.4%); 237 items were identified in questionnaires and linked to 39 ICF categories. Core issues in questionnaires ("pain," "walking," "stairs") were important concerns for patients, but other key patient concerns ("swelling," "recreation and leisure," "sports") were seldom included in questionnaires.

CONCLUSION

No single questionnaire captured all patient concerns, and standardized questionnaires differed largely in content. This analysis may help guide development of a more comprehensive instrument for evaluating outcomes following ankle reconstruction.

CLINICAL RELEVANCE

When choosing an outcome questionnaire, clinicians and researchers should consider the targeted outcome because no one questionnaire captures the full patient experience.

Examining the similarities and differences of OMERACT core sets using the ICF: first step towards an improved domain specification and development of an item pool to measure functioning and health

OBJECTIVE

To contribute to the discussion on a common approach for domain selection in the Outcomes in Rheumatology Clinical Trials (OMERACT) process. First, this article reports on the consistency in the selection and names of the domains of the current OMERACT core set, and next on the comparability of the specifications of concepts that are relevant within the domains. For this purpose, a convenience sample of 4 OMERACT core sets was used: rheumatoid arthritis (RA), psoriatic arthritis (PsA), longitudinal observational studies (LOS) in rheumatology, and ankylosing spondylitis (AS). Domains from the different core sets were compared directly. To be able to compare the specific content of the domains, the concepts contained in the questionnaires that were considered or proposed to measure the domains were identified and linked to the category of the International Classification of Functioning, Disability, and Health (ICF) that best fit that construct. Large differences in the domains, and lack of domain definitions, were noted among the 4 OMERACT core sets. When comparing the concepts in the questionnaires that represent the domains, core sets differed also in the number and type of constructs that were addressed within each of the domains. Especially for the specification of the concepts within the domains Discomfort and Disability, the ICF proved to be useful as external reference to classify the different constructs. Our exercise suggests that the OMERACT process could benefit from a standardized approach to select, define, and specify domains, and demonstrated that the ICF is useful for further classification of the more specific concepts of "what to measure" within the domains. A clear definition and classification of domains and their specification can be useful as a starting point to build a pool of items that could then be used to develop new instruments to assess functioning and health for rheumatological conditions.

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.

Applying the impairment, activity limitation, and participation restriction constructs of the ICF model to osteoarthritis and low back pain trials: a reanalysis

OBJECTIVE

To test the hypothesis that interventions targeting the relief of pain and disability in musculoskeletal diseases may have differential effects on activity limitation and participation restriction as defined in the International Classification of Functioning, Disability and Health (ICF).

METHODS

Full data were obtained for 3 randomized controlled trials that used the Western Ontario and McMaster Universities Osteoarthritis Measure (WOMAC), the Medical Outcomes Study Short-form 36 (SF-36), or the Oswestry Disability Questionnaire as their primary outcome measures. The trial outcomes were reanalyzed using items previously designated as assessing pure activity limitation (A) or participation restriction (P), or a mixture of the 2 (A/P) only, and the results compared with the outcomes found using the full scales, which assess a mixture of outcome domains.

RESULTS

The results did not refute the hypothesis. An exercise-based intervention and injection therapies both appeared to have more effect on participation restriction (P) than on activity limitation (A), while a drug-based intervention had more effect on A than on P.

CONCLUSION

Different interventions used to treat musculoskeletal disorders may have differential effects on impairment, activity limitation, and restricted participation. The use of outcome measures that do not differentiate these 3 domains may obscure the true value of an intervention.

[Introduction to the international classification of functioning, disability and health (ICF)]

The WHO International Classification of Functioning, Disability and Health (ICF) allows a standardized description of functioning and disability based on individual and contextual factors. The ICF adopts a biopsychosocial model of disability and functioning and is complementary to the ICD-10 (International Classification of Diseases). For its implementation in clinical practice ICF-based instruments, such as the ICF core sets were developed in a standardized scientific process. These consist of the ICF categories which are most relevant for patients with specific diseases or in specific health care situations. In trauma care the ICF and ICF core sets can be applied in defined health problems and treatment situations for documentation of functioning, structured planning and implementation of interventions as well as outcome assessment.

The OMERACT-ICF Reference Group: Integrating the ICF into the OMERACT Process: Opportunities and Challenges

At OMERACT 8 in May 2006 in Malta, the International Classification of Functioning, Disability and Health (ICF) was introduced as a universal model and a universal classification to describe human functioning. The potential usefulness of the ICF for the OMERACT process was highlighted and reported in a position paper following the OMERACT 8 meeting. Since then representatives of several OMERACT working groups with an interest in the ICF joined an OMERACT-ICF reference group. Most members had experience with the ICF and worked further to integrate the ICF into OMERACT. We describe the main roles of the ICF in the OMERACT process and the challenges when practice confronts theory.

How to apply the ICF and ICF core sets for low back pain

OBJECTIVE

To introduce the International Classification of Functioning, Disability and Health (ICF) as conceptual model and classification and the ICF Core Sets as a way to specify functioning for a specific health condition such as Low Back Pain, and to illustrate the application of the ICF and ICF Core Sets in the context of clinical practice, the planning and reporting of studies and the comparison of health status measures.

METHODS

A decision-making and consensus process was performed to develop the ICF Core Sets for Low Back Pain, the linking procedure was applied as basis for the content comparison of health-status measures and the Rehab-Cycle was used to exemplify the application of the ICE and ICF Core Sets in clinical practice.

RESULTS

Two different ICF Core Sets, namely, a comprehensive and a brief, are presented, three different health-status measures were linked to the ICF and compared and a case example of a patient with Low back Pain was described based on the Rehab-Cycle.

DISCUSSION

The ICF is a promising new framework and classification to assess the impact of Low Back Pain. The ICF and practical tools, such as the ICF Core Sets for Low Back Pain, are useful for clinical practice, outcome and rehabilitation research, education, health statistics, and regulation.

A framework for assessment in oncology rehabilitation

Although the incidence of cancer in the United States is high, improvements in early diagnosis and treatment have significantly increased survival rates in recent years. Many survivors of cancer experience lasting, adverse effects caused by either their disease or its treatment. Physical therapy interventions, both established and new, often can reverse or ameliorate the impairments (body function and structure) found in these patients, improving their ability to carry out daily tasks and actions (activity) and to participate in life situations (participation). Measuring the efficacy of physical therapy interventions in each of these dimensions is challenging but essential for developing and delivering optimal care for these patients. This article describes the acute and long-term effects of cancer and its treatment and the use of the World Health Organization's International Classification of Functioning, Disability and Health (ICF) as a basis for selection of assessment or outcome tools and diagnostic or screening tools in this population.

Developing core sets for persons with traumatic brain injury based on the international classification of functioning, disability, and health

The authors outline the process for developing the International Classification of Functioning, Disability, and Health (ICF) Core Sets for traumatic brain injury (TBI). ICF Core Sets are selections of categories of the ICF that identify relevant categories of patients affected by specific diseases. Comprehensive and brief ICF Core Sets for TBI should become useful for clinical practice and for research. The final definition of the ICF Core Sets for TBI will be determined at an ICF Core Sets Consensus Conference, which will integrate evidence from preliminary studies. The development of ICF Core Sets is an inclusive and open process and rehabilitation professionals are invited to participate.

Towards an ICF Core Set for chronic musculoskeletal conditions: commonalities across ICF Core Sets for osteoarthritis, rheumatoid arthritis, osteoporosis, low back pain and chronic widespread pain

The objective of the study was to identify commonalities among the International Classification of Functioning, Disability and Health (ICF) Core Sets of osteoarthritis (OA), osteoporosis (OP), low back pain (LBP), rheumatoid arthritis (RA) and chronic widespread pain (CWP). The aim is to identify relevant categories for the development of a tentative ICF Core Set for musculoskeletal and pain conditions. The ICF categories common to the five musculoskeletal and pain conditions in the Brief and Comprehensive ICF Core Sets were identified in three steps. In a first step, the commonalities across the Brief and Comprehensive ICF Core Sets for these conditions were examined. In a second and third step, we analysed the increase in commonalities when iteratively excluding one or two of the five conditions. In the first step, 29 common categories out of the total number of 120 categories were identified across the Comprehensive ICF Core Sets of all musculoskeletal and pain conditions, primarily in the component activities and participation. In the second and third step, we found that the exclusion of CWP across the Comprehensive ICF Core Sets increased the commonalities of the remaining four musculoskeletal conditions in a maximum of ten additional categories. The Brief ICF Core Sets of all musculoskeletal and pain conditions contain four common categories out of a total number of 62 categories. The iterative exclusion of a singular condition did not significantly increase the commonalities in the remaining. Based on our analysis, it seems possible to develop a tentative Comprehensive ICF Core Set across a number of musculoskeletal conditions including LBP, OA, OP and RA. However, the profile of functioning in people with CWP differs considerably and should not be further considered for a common ICF Core Set.

Physical disability due to musculoskeletal conditions

Musculoskeletal conditions (MSC) are common throughout the world and their impact on individuals is diverse and manifold. Knowledge of the determinants for disability and of strategies for prevention and rehabilitation management according to the scientific evidence is critical for reducing the burden of MSC. The first section of this chapter reviews the evidence for common determinants of functioning and disability in patients with MSC. We have focussed on environmental factors (EF) and personal factors (PF) and have structured them according to the International Classification of Functioning, Disability and Health (ICF) framework. The second section discusses prevention strategies. Generally, prevention needs to address those EF and PF that were presented in the first section. The final section describes modern principles of rehabilitation and reviews the evidence for specific rehabilitation interventions.
