• Comparison of Standard Clinical and Instrumented Physical Performance Tests in Discriminating Functional Status of High-Functioning People Aged 61–70 Years Old 

      Coni, Alice; Van Ancum, Jeanine M.; Bergquist, Ronny; Mikolaizak, A. Stefanie; Mellone, Sabato; Chiari, Lorenzo; Maier, Andrea B.; Pijnappels, Mirjam (Journal article; Peer reviewed, 2019)
      Assessment of physical performance by standard clinical tests such as the 30-s Chair Stand (30CST) and the Timed Up and Go (TUG) may allow early detection of functional decline, even in high-functioning populations, and ...

Stefanie; Boulton, Elisabeth; Jonkman, Nini H.; Maier, Andrea B.; Klenk, Jochen; Helbostad, Jorunn L.; Taraldsen, Kristin; Aminian, Kamiar (Journal article; Peer reviewed, 2018)
      The emerging mHealth applications, incorporating wearable sensors, enables continuous monitoring of physical activity (PA). This study aimed at analyzing the relevance of a multivariate complexity metric in assessment of ...
    • Concurrent validity and reliability of the Community Balance and Mobility Scale in young-older adults. 

      Weber, Michaela; Van Ancum, Jeanine M.; Bergquist, Ronny; Taraldsen, Kristin; Gordt, Katharina; Mikolaizak, A. Stefanie; Nerz, Corinna; Pijnappels, Mirjam; Jonkman, Nini H.; Maier, Andrea B.; Helbostad, Jorunn L.; Vereijken, Beatrix; Becker, Clemens; Schwenk, Michael (Journal article; Peer reviewed, 2018)
      Background With the growing number of young-older adults (baby-boomers), there is an increasing demand for assessment tools specific for this population, which are able to detect subtle balance and mobility deficits. ...
    • Creating and Validating a Shortened Version of the Community Balance and Mobility Scale for Application in People Who Are 61 to 70 Years of Age 

      Gordt, Katharina; Mikolaizak, A. Stefanie; Taraldsen, Kristin; Bergquist, Ronny; Van Ancum, Jeanine M.; Nerz, Corinna; Pijnappels, Mirjam; Maier, Andrea B.; Helbostad, Jorunn L.; Vereijken, Egberta; Becker, Clemens; Schwenk, Michael (Peer reviewed; Journal article, 2020)
      Background The Community Balance and Mobility Scale (CBM) has been shown to be reliable and valid for detecting subtle balance and mobility deficits in people who are 61 to 70 years of age. However, item redundancy and ...
    • The FARSEEING real-world fall repository: a large-scale collaborative database to collect and share sensor signals from real-world falls 

      Klenk, Jochen; Schwickert, Lars; Palmerini, Luca; Mellone, Sabato; Bourke, Alan; Ihlen, Espen Alexander F.; Kerse, Ngaire; Hauer, Klaus; Pijnappels, Mirjam; Synofzik, Matthis; Srulijes, Karin; Maetzler, Walter; Helbostad, Jorunn L.; Zijlstra, Wiebren; Aminian, Kamiar; Todd, Christopher; Chiari, Lorenzo; Becker, Clemens (Peer reviewed; Journal article, 2016)
      Background Real-world fall events objectively measured by body-worn sensors can improve the understanding of fall events in older people. However, these events are rare and hence challenging to capture. Therefore, the ...
    • Fractional stability of trunk acceleration dynamics of daily-life walking: toward a unified concept of gait stability 

      Ihlen, Espen Alexander F.; van Schooten, Kimberley S; Bruijn, Sjoerd M; Pijnappels, Mirjam; van Dieen, Jaap H (Journal article; Peer reviewed, 2017)
      Over the last decades, various measures have been introduced to assess stability during walking. All of these measures assume that gait stability may be equated with exponential stability, where dynamic stability is ...
    • Mobile health applications to promote active and healthy ageing 

      Helbostad, Jorunn L.; Vereijken, Beatrix; Becker, Clemens; Todd, Chris; Taraldsen, Kristin; Pijnappels, Mirjam; Aminian, Kamair; Mellone, Sabato (Journal article; Peer reviewed, 2017)
      The European population is ageing, and there is a need for health solutions that keep older adults independent longer. With increasing access to mobile technology, such as smartphones and smartwatches, the development and ...
