- Falls are common among persons with late effects of polio (LEoP), which may lead to fear of falling and activity avoidance in everyday life. Here, we assessed the occurrence of fall-related activity avoidance among persons with LEoP and explored how these experiences influenced daily life. Fourteen ambulatory persons (seven women; mean age 70 years) with LEoP participated. They responded to the modified Survey of Activities and Fear of Falling in the Elderly (mSAFFE) and participated in individual interviews, which were analysed by systematic text condensation. Each quotation was deductively analysed from its representation with regard to mSAFFE. We found that many persons often avoided activities related to standing and walking, for example, taking a bath, performing household chores, walking outdoors, attending social events if there were stairs in the building and travelling by public transport, due to fear of falling, increased pain and fatigability. To facilitate the performance of daily activities participants expressed that strategic thinking and aids were important to use. In conclusion, fall-related activity avoidance is common in persons with LEoP, which negatively influence daily life and social participation. To increase daily functioning in this population, fall-related activity avoidance should be included in a multifaceted fall management program.

- BACKGROUND: Many persons with late effects of polio (LEoP) perceive walking limitations in everyday life. A common rating scale to assess walking limitations is the Walking Impact Scale (Walk-12). However, there is limited knowledge about its psychometric properties.OBJECTIVE: To investigate the psychometric properties of Walk-12 in persons with LEoP.DESIGN: Rasch model analysis of cross-sectional data.SETTING: University Hospital.PARTICIPANTS: A total of 325 persons with LEoP (175 women; mean age 70 ± 10 yr).MAIN OUTCOME MEASUREMENT: The Walk-12, comprising 12 items with five response categories ranging from 1 (not at all) to 5 (extremely).METHODS: Data of Walk-12 were collected by a postal survey. The Rasch model analysis was used to analyze unidimensionality of the scale, local dependency, targeting, hierarchical order of items, Differential Item Functioning (DIF), response category functioning and reliability (Person Separation Index, PSI). Raw score transformation to interval measurements was also performed.RESULTS: The analysis revealed that Walk-12 was multidimensional and suffered from some local dependency. Targeting was compromised among persons with less and worse walking limitations. Hierarchically, the most difficult item to perform was "running" and the easiest was "walking indoors with support". There was a minor DIF for gender in one item ("support when walking outdoors"). Reliability was high (PSI = 0.94). Disordered response category thresholds were found for three items; when merging the middle response categories for these items model fit slightly improved and unidimensionality was achieved.CONCLUSION: The Walk-12, in its current version, does not fully meet the rigorous psychometric Rasch measurement standards in persons with LEoP. Further development of the scale is warranted, including merging response categories and complementing Walk-12 with objective measures of gait in order to improve targeting. As these limitations can be considered minor, the current version of Walk-12 can still be useful for research and clinical practice. This article is protected by copyright. All rights reserved.
