Stakeholder needs assessment for developing ageing in place solutions - a qualitative study.

BACKGROUND: Ageing in place is a common desire among older adults and people in need of care. Accessible housing and ambient assisted living (AAL) technologies can help to live independently at home. However, they cannot replace the human support network of informal caregivers, healthcare professionals and social workers. The needs of these stakeholders should be considered and analysed in order to develop user-friendly and acceptable (digital) solutions for ageing in place while supporting human support networks in fulfilling their roles. This paper presents the first step for a comprehensive multi-level needs analysis within the framework of an user-centered design thinking approach. METHODS: Guideline-based interviews were conducted with healthcare professionals, social workers and an informal caregiver to collect data about the needs of older adults as well as people in need of care, and their human support networks. RESULTS: The call for more information that is easier to find is a common desire of the three groups. There is agreement on system-based communication and orientation problems, the existence of physical and psychological stress exacerbated by a lack of human resources, the desire for personalised care, the need to feel safe and supported in emergencies, and the need for advice and help with administrative tasks. Overall, the needs of one group are closely linked to those of the other. CONCLUSION: Stakeholder selection and diversity are decisive for findings about ageing in place. The overlaps between the stakeholders' needs offer chances and challenges at the same time for the development of user-friendly, acceptable (digital) solutions and products that support ageing in place.

Self-perceived foot function and pain in children and adolescents with flexible flatfeet - Relationship between dynamic pedobarography and the foot function index.

BACKGROUND: There is considerable debate as to which parameters to include in the assessment of paediatric flatfeet. Dynamic pedobarography is an objective, dynamic method to measure foot function. Information about its associations to patient-reported measures may help to focus on the most relevant parameters. RESEARCH QUESTION: What is the association between the Foot Function Index and pedobarographic assessments in flatfeet of children and adolescents? METHODS: A consecutive clinical case series of 51 participants with idiopathic flexible flatfeet aged 7-17 years underwent barefooted pedobarography during gait and completed the Foot Function Index Questionnaire. Pedobarographic data categorized into values related to area, peak pressure and force with respect to the hind-, mid- and forefoot were extracted. To test the associations between the Foot Function Index and pedobarographic assessments, bivariate partial correlations were tested and contact times served as co-variate. RESULTS: Several significant associations between peak pressure or forces beneath the hindfoot, midfoot and hallux to self-perceived function were found (|rho| = 0.28-.46, P < 0.05). In particular, reduced peak forces and pressures underneath the hindfoot and hallux, a lateral shift (smaller medio-lateral ratios) of hindfoot pressure and force and a medial shift (larger medio-lateral ratios) of midfoot pressure seem to be negatively associated with foot-related disability. Overall, less evidence was noted for associations to pain scores. Area related outcomes (including the arch index) contained no information for function while a larger BMI was the strongest thread for disability (rho = 0.42, P = 0.002) and pain (rho = 0.31, P = 0.027). SIGNIFICANCE: When using pedobarography for the assessment of flexible flatfeet of children and adolescents, less attention should be paid to area related measurements which do not provide information about self-perceived function or disability. Instead, peak pressures or forces in the hind- or midfoot or beneath the hallux may be focussed. Weight reductions are potentially an effective strategy to reduce or prevent symptoms.

Cluster analysis to identify foot motion patterns in children with flexible flatfeet using gait analysis-A statistical approach to detect decompensated pathology?

INTRODUCTION: The paediatric flexible flatfoot constitutes the major cause of clinic visits for orthopaedic foot problems. It shows variations of deformities in different planes and locations of the foot and its indication for treatment have been extensively discussed. Despite its high prevalence there exists no classification of flatfeet during walking as a prerequisite for treatment decision. Therefore, the aim of this study is to classify flexible flatfeet based on 3D foot kinematics during walking. METHODS: Patients age 7-17 years with flexible flatfeet (N = 129, 255 feet) of non-neurogenic or syndromic origin, were retrospectively included. Patients underwent gait analysis using the Oxford Foot Model after standard clinical examination. A k-means cluster analysis was performed on 3 scores derived from the principal component analysis of the foot kinematic waveforms over the gait cycle. Gait and clinical parameters were then statistically tested between clusters. RESULTS: Cluster analysis revealed two groups of flexible flatfeet that were discriminated best by the inversion at push-off during walking. Cluster 2, including 110 feet, showed an average eversion instead of an inversion at push-off and a lower number of heel rises in the clinical test. Both was significantly different between clusters (p < 0.001). DISCUSSION: Based on the findings, the resultant clusters can be interpreted as describing compensated and decompensated feet, with the latter presenting a group that may require surgical interventions, even if they are not yet present with pain. The hindfoot inversion capability at push-off is the most important variable in the 3D gait analysis to classify flexible flat feet.
