    A Biologically Inspired Movement Recognition System with Spiking Neural Networks for Ambient Assisted Living Applications

    by Athanasios Passias, Karolos-Alexandros Tsakalos, Ioannis Kansizoglou, Archontissa Maria Kanavaki, Athanasios Gkrekidis, Dimitrios Menychtas, Nikolaos Aggelousis, Maria Michalopoulou, Antonios Gasteratos, Georgios Ch. Sirakoulis

    This study presents a novel solution for ambient assisted living (AAL) applications that utilizes spiking neural networks (SNNs) and reconfigurable neuromorphic processors. As demographic shifts result in an increased need for eldercare, due to a large elderly population that favors independence, there is a pressing need for efficient solutions. Traditional deep neural networks (DNNs) are typically energy-intensive and computationally demanding. In contrast, this study turns to SNNs, which are more energy-efficient and mimic biological neural processes, offering a viable alternative to DNNs. We propose asynchronous cellular automaton-based neurons (ACANs), which stand out for their hardware-efficient design and ability to reproduce complex neural behaviors. By utilizing the remote supervised method (ReSuMe), this study improves spike train learning efficiency in SNNs. We apply this to movement recognition in an elderly population, using motion capture data. Our results highlight a high classification accuracy of 83.4%, demonstrating the approach’s efficacy in precise movement activity classification. This method’s significant advantage lies in its potential for real-time, energy-efficient processing in AAL environments. Our findings not only demonstrate SNNs’ superiority over conventional DNNs in computational efficiency but also pave the way for practical neuromorphic computing applications in eldercare.

    Physical activity, sedentary behaviour and well-being: experiences of people with knee and hip osteoarthritis

    by Archontissa M. Kanavaki, Alison Rushton, Elizabeth Hale, Rainer Klocke, Abhishek Abhishek, Joan L. Duda

    Living with knee and hip osteoarthritis (OA) means living with pain and difficulty in movement. Given the beneficial effects of physical activity (PA) and reduction of sedentary behaviour (SB), these behaviours need to be understood in the context of individuals’ daily lives and sense of well-being. Twelve individuals (age: 43–79 years; 67% female) with knee and/or hip OA purposively selected (e.g., age, OA duration, OA severity) participated in semi-structured interviews. Data was analysed using inductive thematic analysis. PA and SB were narrated as multifaceted experiences with two overarching themes, PA negotiations (valuing mobility, the burden of osteoarthritis, keep going, the feel-good factor), SB negotiations (the joy of sitting, a lot is too bad, the osteoarthritis confines), and two overlapping themes (the life context, finding a balance). Physical and psychological aspects of PA and SB experiences were interwoven. Participants valued mobility and were proactively trying to preserve it by keeping active. A constant negotiation among the OA burden, the need to enjoy life and life circumstances was underlying PA behaviour. Prescription and encouragement of a physically active lifestyle in this population should be linked to mobility-related personal values and sense of well-being, while addressing concerns around OA-safety and normalizing PA trade-offs.

    Kidney Care during COVID-19 in the UK: Perspectives of Healthcare Professionals on Impacts on Care Quality and Staff Well-Being

    by Archontissa Maria Kanavaki, Courtney Jane Lightfoot, Jared Palmer, Thomas James Wilkinson, Alice Caroline Smith, Ceri Rhiannon Jones

    In light of the rapid changes in healthcare delivery due to COVID-19, this study explored kidney healthcare professionals’ (HCPs) perspectives on the impact of these changes on care quality and staff well-being. Fifty-nine HCPs from eight NHS Trusts across England completed an online survey and eight took part in complementary semi-structured interviews between August 2020 and January 2021. Free-text survey responses and interviews were analysed using inductive thematic analysis. Themes described the rapid adaptations, concerns about care quality, benefits from innovations, high work pressure, anxiety and mental exhaustion in staff and the team as a well-being resource. Long-term retention and integration of changes and innovations can improve healthcare access and efficiency, but specification of conditions for its use is warranted. The impact of prolonged stress on renal HCPs also needs to be accounted for in quality planning. Results are further interpreted into a theoretical socio-technical framework.

    Barriers and facilitators of physical activity in knee and hip osteoarthritis: a systematic review of qualitative evidence

    by Archontissa M Kanavaki, Alison Rushton, Nikolaos Efstathiou, Asma Alrushud, Rainer Klocke, Abhishek Abhishek, Joan L Duda

    Physical activity (PA), including engagement in structured exercise, has a key role in the management of hip and knee osteoarthritis (OA). However, maintaining a physically active lifestyle is a challenge for people with OA. PA determinants in this population need to be understood better so that they can be optimised by public health or healthcare interventions and social policy changes. Objectives The primary aim of this study is to conduct a systematic review of the existing qualitative evidence on barriers and facilitators of PA for patients with hip or knee OA. Secondary objective is to explore differences in barriers and facilitators between (1) lifestyle PA and exercise and (2) PA uptake and maintenance. Methods Medline, Embase, Web of Science, Cumulative Index to Nursing and Allied Health Literature, SPORTDiscus, Scopus, Grey literature and qualitative journals were searched. Critical Appraisal Skills Programme—Qualitative checklist and Lincoln and Guba’s criteria were used for quality appraisal. Thematic synthesis was applied. Findings Ten studies were included, seven focusing on exercise regimes, three on overall PA. The findings showed a good fit with the biopsychosocial model of health. Aiming at symptom relief and mobility, positive exercise experiences and beliefs, knowledge, a ‘keep going’ attitude, adjusting and prioritising PA, having healthcare professionals’ and social support emerged as PA facilitators. Pain and physical limitations; non-positive PA experiences, beliefs and information; OA-related distress; a resigned attitude; lack of motivation, behavioural regulation, professional support and negative social comparison with coexercisers were PA barriers. All themes were supported by high and medium quality studies. Paucity of data did not allow for the secondary objectives to be explored. Conclusion Our findings reveal a complex interplay among physical, personal including psychological and social-environmental factors corresponding to the facilitation and hindrance of PA, particularly exercise, engagement. Further research on the efficacy of individualised patient education, psychological interventions or social policy change to promote exercise engagement and lifestyle PA in individuals with lower limb OA is required.
