Abstract Background The World Health Organization Disability Assessment Schedule 2.0 12-item survey (WHODAS-12) is a questionnaire developed by the WHO to measure functioning across health conditions, cultures, and settings. WHODAS-12 consists of a subset of the 36 items of WHODAS-2.0 36-item questionnaire. Little is known about the minimal important difference (MID) of WHODAS-12 in persons with chronic low back pain (LBP), which would be useful to determine whether rehabilitation improves functioning to an extent that is meaningful for people experiencing the condition. Our objective was to estimate an anchor-based MID for WHODAS-12 questionnaire in persons with chronic LBP. Methods We analyzed data from two cohort studies (identified in our previous systematic review) conducted in Europe that measured functioning using the WHODAS-36 in adults with chronic LBP. Eligible participants were adults with chronic LBP with scores on another measure as an anchor to indicate participants with small but important changes in functioning over time [Short-form-36 Physical Functioning (SF36-PF) or Oswestry Disability Index (ODI)] at baseline and follow-up (study 1: 3-months post-treatment; study 2: 1-month post-discharge from hospital). WHODAS-12 scores were constructed as sums of the 12 items (scored 0–4), with possible scores ranging from 0 to 48. We calculated the mean WHODAS-12 score in participants who achieved a small but meaningful improvement on SF36-PF or ODI at follow-up. A meaningful improvement was an MID of 4–16 on ODI or 5–16 on SF36-PF. Results Of 70 eligible participants in study 1 (mean age = 54.1 years, SD = 14.7; 69% female), 18 achieved a small meaningful improvement based on SF-36 PF. Corresponding mean WHODAS-12 change score was − 3.22/48 (95% CI -4.79 to -1.64). Of 89 eligible participants in study 2 (mean age = 65.5 years, SD = 11.5; 61% female), 50 achieved a small meaningful improvement based on ODI. Corresponding mean WHODAS-12 change score was − 5.99/48 (95% CI − 7.20 to -4.79). Conclusions Using an anchor-based approach, the MID of WHODAS-12 is estimated at -3.22 (95% CI -4.79 to -1.64) or -5.99 (95% CI − 7.20 to -4.79) in adults with chronic LBP. These MID values inform the utility of WHODAS-12 in measuring functioning to determine whether rehabilitation or other health services achieve a minimal difference that is meaningful to patients with chronic LBP.

Abstract Background Fibromyalgia (FM) is a chronic condition characterized by widespread musculoskeletal pain, fatigue, intestinal disorders, mood swings, and sleep disturbances. To the best of our knowledge, the questionnaire used for assessing problems and difficulties in the functioning of people with FM has not been translated and adapted in Poland so far. The aim of the study was to assess the psychometric properties of the Polish version of the Fibromyalgia Impact Questionnaire (FIQ-Pol). Material and method The study covered 150 people with FM living in Poland. The measurement reliability, internal structure, repeatability, and validity of the Polish version of the FIQ were examined. Results The scale score reliability of the entire tool for the research group was very good. The alpha Cronbach's test result for the whole scale was 0.84. The repeatability of the scale measured by the test–retest method using the interclass correlation coefficients (ICC) was very good and amounted to 0.96. Internal structure suggested by FIQ-Pol authors was confirmed (Confirmatory factor analysis). After introducing modification indices for the entire scale, satisfactory parameter values were obtained, i.e.: RMSEA (0.06), CFI (0.97) and TLI (0.96). Theoretical validity was assessed by correlating the results of the Polish version of the FIQ with the results of the Beck's Depression Inventory (BDI). Both the FIQ-Pol total score and its domains showed strong positive correlations with BDI. Conclusion The Polish FIQ is a reliable and valid tool to measure the functional disability and health status of Polish people with FM.

Objectives The aim of this work was to assess the work ability, health status, disability and quality of life of working people of pre-retirement and retirement age, as well as to analyze factors affecting the ability to perform work in older age. Material and Methods A cross-sectional pilot study was conducted in the Podkarpackie and Świętokrzyskie voivodeships, Poland, in randomly selected workplaces of intellectual nature. It was carried out by means of direct interviews in the workplace of the surveyed people, using the Work Ability Index , a questionnaire based on the WHO Disability Assessment Schedule 2.0 , the WHO Quality of Life-BREF questionnaire , the Geriatric Depression Scale , and the Visual Analogue Scale (VAS). The criteria for inclusion were: age 55–75 years and informed consent to participate in the study. Overall, 201 complete questionnaires were included in the analysis. Demographic data is presented using descriptive statistics measurements. The logistic regression model was used to identify factors related to work ability. Results The vast majority (69.66%) of employees performing intellectual work had moderate or poor work ability. The average level of general disability in the studied group was mild (20.65), and the quality of life was quite good (64.73). A significant problem among the surveyed people was a quite high average level of pain (VAS = 3.99), the occurrence of depression (73.63%), as well as musculoskeletal (64.18%) and cardiovascular diseases (52.24%). The most important factor contributing to a better work ability was the adaptation of the workplace to functional and healthrelated needs (OR = 7.79). Psychological well-being (OR = 1.12), cognitive performance (OR = 0.97) and a smaller number of chronic diseases (OR = 0.58) were also important factors. Conclusions Preparation of elderly people for professional activity should be conducted in 2 different ways, i.e., by means of education and implementation of an active, healthy lifestyle, and increasing control over one’s own health and factors determining it, as well as by the proper organization of working space, and quick access to treatment and rehabilitation, especially in the case of musculoskeletal and cardiovascular diseases.

Introduction There is a growing number of older people in Poland. This phenomenon results in the need to assess their problems related with functioning in everyday life. This is the first study conducted in Polish society which evaluates the prevalence of disability and limitations in functioning by means of WHODAS 2.0 questionnaire. Objective Evaluation of the health, functioning and disability of people aged 60–70 years living in south-eastern Poland. Material and Methods The researched material was a randomly- selected sample of 1,000 inhabitants of south-eastern Poland. The study was conducted by use of direct interviews applying the WHODAS 2.0. For the purpose of statistical analysis, measures of descriptive statistics and non-parametric tests of significance were used. Results Limitations in functioning were reported by 67.00% of participants aged 60–70 years, including 46.20% with a mild disability, 14.50% – moderate, 6.30% – significant and extremely large disability. The highest level of disability occurred in areas related to participation in social life (mean = 20.77), performing activities of daily living (mean = 17.42) and mobility (mean = 17.23). A significantly higher level of disability (p

Abstract Background The interest in physiotherapy programs for individuals in hospice is increasing. The aim of our study was to assess the impact of a multi-component, individualized physiotherapy program on the functional and emotional conditions and quality of life of patients receiving hospice services in the home. Methods The study included 60 patients (mean 66.3 years) receiving hospice services in the home. A model of a physiotherapy program was designed, including breathing, strengthening, transfer, gait, balance, functional, and ergonomic exercises, as well as an adaptation of the patient’s living environment to functional needs. The tests were performed before and after the intervention. The study used the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales, the World Health Organization Quality of Life - Bref (WHOQOL-BREF), the Visual Analogue Scale (VAS) pain scale, the Tinetti POMA Scale, and the Geriatric Depression Scale (GDS). To enable comparison of our results worldwide, a set of International Classification of Functioning, Disability and Health (ICF) categories was used. Results The average functional level of the ADL (mean 2.9) and the IADL (mean 11.9), as well as the WHOQOL-BREF (mean 46.4) of the patients before the intervention were low, whereas the intensity of pain (VAS mean 5.8), the risk of falling (Tinetti mean 8.2), and depression (GDS mean 16.7) were recorded as high. After the completion of the intervention program, a significant improvement was found in the ADL (mean 4.0), IADL (mean 13.9), WHOQOL-BREF (mean 52.6), VAS (mean 5.1), risk of falling (Tinetti mean 12.3), and GDS (mean 15.7) scores. Conclusions The physiotherapeutic intervention had a significant impact on improving the performance of ADL, as well as the emotional state and quality of life of patients receiving hospice services in the home. The results of our research provide evidence of the growing need for physiotherapy in individuals in hospice and for comprehensive assessment by means of ICF.

Abstract Background The extension of the life span has led to an increase in the number of older people and an increase in the prevalence of disability in people over 60 years of age. The aim of this study was to assess the prevalence of ADL and IADL disability and to analyze its determinants among people aged 60 and older living in southeastern Poland. Methods This cross-sectional study was carried out among a randomly selected, representative population of people aged 60 and older living in southeastern Poland. Disability was assessed using the Katz Index of Independence in Basic Activities of Daily Living and Instrumental Activities of Daily Living. Logistic regression models were used to identify the factors related to ADLs and IADLs. For the variables that were included in the above models, their clustered influence on the increase in the odds ratio for the occurrence of an ADL or IADL limitation was also examined. Results The research results show that 35.75% of the participants reported at least one problem with IADLs. At least one problem with ADLs was reported by 17.13% of the participants. The most significant modifiable factors influencing the occurrence of disability were the presence of barriers in the participant’s environment, poor relations with relatives, a lack of social contacts, multimorbidity and pain. A multiple increase in the odds ratio of disability was found with the presence of pairs of analyzed factors. The highest odds ratio of at least one ADL limitation was observed for the combination of barriers in the participant’s environment with multimorbidity (OR 74.07). With regard to IADL disability, the highest odds ratio was observed for the combination of pain on the VAS scale ≥3 points with older age (OR 19.47). Conclusions The study showed a high prevalence of ADL and IADL disability in older people living in southeastern Poland. It also indicated the extent to which modifiable factors influenced the occurrence of disability and the extent to which the risk of disability increased with the presence of pairs of factors, especially those that included environmental barriers in the participant’s environment.
