The Mobility Monitor: supporting safe mobility in the home environment.

Projectomschrijving

Inzicht in bewegingsprofielen
Fysieke activiteit en individuele bewegingsprogramma’s zijn sleutel tot succes bij het voorkomen van functionele achteruitgang van chronisch zieken en oudere mensen. Het Universitair Medisch Centrum Groningen (UMCG) ontwikkelt in samenwerking met Philips Research de Mobility Monitor: een klein, draagbaar apparaatje dat de individuele dagelijkse bewegingsprofielen objectief weergeeft. Inzicht in de bewegingsprofielen maakt het mogelijk gericht te sturen in bewegingsinterventies. Het UMCG en Philips richten zich op het vinden van de juiste technische oplossingen en op het gebruik van het apparaatje in de praktijk. Een zeer innovatief aspect is de toepassing van techniek voor de beoordeling van spierkracht tijdens de bewegingsactiviteit

Doelstelling
De Mobility Monitor geeft input voor maatwerk bewegingsinterventies en leidt zo tot een grotere ‘mobiele’ veiligheid in de thuisomgeving. Door implementatie van het systeem in telezorgsystemen kan de Mobility Monitor bijdragen aan meer zelfcontrole, zelfregulering en onafhankelijker functioneren van ouderen.

Samenvatting van de aanvraag

The present project offers the opportunity for a significant advance in supporting safe mobility in the home environment by developing the Mobility Monitor; an innovative diagnostic device which provides information about individual mobility profiles in daily life. At present, the clinical fields addressing motor functioning are in lack of adequate instruments for assessing balance function and the performance of mobility related activities such as rising from a chair, standing, and walking. Objective laboratory-based methods for movement analysis are time-consuming, costly and they are rarely available to health-care professionals. More importantly, laboratory methods are often unsuitable for functional assessment in patients or older persons, and they cannot yield valid assessments of the quantity and quality of performing mobility related activities in daily life. Based on a miniature on-body measurement system, the Mobility Monitor will overcome limitations of laboratory methods without loosing the advantage of precise analyses. Thus, the Mobility Monitor will be a highly valuable tool for increasing the effectiveness of interventions aiming to improve functioning and independent mobility. Current evidence indicates that maintaining appropriate levels of safe physical activity, and individually tailored exercise programs are a key to success in preventing functional decline in older people. Measures of mobility, balance and muscle function are important indicators of motor functioning and strong predictors for frailty and risk-of-falling. Studies have demonstrated that, even in old people, loss of muscle strength is not irreversible and the combination of exercises to increase muscle force and train dynamic balance can improve functioning and reduce the risk of falls. Therefore, accurate measures of mobility, balance and muscle function are highly relevant for monitoring progress or decline of motor functioning in persons with chronic conditions, and older people at risk of transitioning to frailty. The impact of wearable systems for objective assessment and monitoring of mobility related activities in real-life on the effectiveness of interventions aiming to improve functioning can be enormous. However, the new technology has not yet entered the clinical fields that address functioning and mobility in older populations. Very few studies have applied monitoring solutions in older people over long durations. Most of the few available studies report on technical validity but do not demonstrate clinical validity. With only few exceptions, studies do not report practical feasibility and acceptance by different users (i.e. patients, informal care-givers, and health-care professionals). These aspects will all be addressed in this proposal. The major challenge for this project is to develop, implement, and evaluate a monitoring solution which can be applied during habitual activities in daily life, and which, on a day-to-day basis, provides a mobility profile indicating quantity and quality of mobility related activities. The project aims to develop an easy-to-use, easy-to-wear, miniature on-body system which can objectify individual mobility profiles in daily life. A highly innovative aspect of the Mobility Monitor will be the implementation of a new approach for assessing muscle power during mobility related activities. A major requirement for the Mobility Monitor is that it demonstrates the feasibility and relevance of (self-) monitoring of mobility by different user groups. Therefore, this project will not only focus on appropriate technical solutions, but also on the clinical validity and practical feasibility of mobility monitoring in older people. This project will: 1. fine-tune and implement hard- and software solutions for measuring aspects of mobility; 2. verify the accuracy of assessing frequency and duration of mobility related activities such as sitting, standing, and (stair-)walking, and of extracting measures of balance performance and lower limb muscle function during activities in daily life; 3. compare outcomes of monitoring solutions with existing instruments for assessing mobility, balance and muscle function; 4. determine the clinical validity and psycho-metric properties of the monitoring methods; 5. use questionnaires and/or interviews to assess different user perspectives, i.e. older people, informal care-givers and health-care professionals; 6. evaluate the implementation of the Mobility Monitor in a home-based intervention. This interdisciplinary project can have a major impact on independent living and quality-of-life of older people. A Mobility Monitor can contribute to independent functioning and reducing fall risk; facilitate the work of health-care professionals such as physical therapists, nurses and general practitioners; can contribute to an evidence-based clinical practice; and can enhance the autonomy of older people by supporting self-regulation.
