• mHealth Support to Stimulate Physical Activity in Individuals With Intellectual Disability: Protocol for a Mixed Methods Pilot Study 

      Michalsen, Henriette; Wangberg, Silje C; Hartvigsen, Gunnar; Henriksen, André; Jaccheri, Maria Letizia; Jahnsen, Reidun Birgitta; Thrane, Gyrd; Arntzen, Cathrine; Anke, Audny Gabriele Wagner (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-15)
      Background: Several studies have shown that individuals with intellectual disabilities (IDs) have low levels of physical activity (PA), and intervention studies on PA suggest inconsistent evidence. The use of technology as a means of motivation for PA has yet to be extensively explored and needs to be further investigated.<p> <p>Objective: We aim to assess the feasibility and acceptability of ...
    • mHealth: Where Is the Potential for Aiding Informal Caregivers? 

      Bradway, Meghan; Woldaregay, Ashenafi Zebene; Issom, David-Zacharie; Pfuhl, Gerit; Hartvigsen, Gunnar; Årsand, Eirik; Henriksen, André (Journal article; Tidsskriftartikkel; Peer reviewed, 2021)
      The health and well-being of informal caregivers often take a backseat to those that they care for. While systems, technologies, and services that provide care and support for those with chronic illnesses are established and continuously improved, those that support informal caregivers are less explored. An international survey about motivations to use mHealth technologies was posted to online ...
    • Physical Activity With Tailored mHealth Support for Individuals With Intellectual Disabilities: Study Protocol for a Randomized Controlled Trial 

      Michalsen, Henriette; Wangberg, Silje C; Hartvigsen, Gunnar; Jaccheri, Maria Letizia; Muzny, Miroslav; Henriksen, André; Olsen, Monica Isabel; Thrane, Gyrd; Jahnsen, Reidun Birgitta; Pettersen, Gunn; Arntzen, Cathrine; Anke, Audny (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-29)
      <i>Background</i>: Individuals with intellectual disabilities (IDs) have lower levels of physical activity (PA) and greater barriers for participation in fitness activities compared with members of the general population. As increased PA has positive effects on cardiovascular and psychosocial health, it is exceedingly important to identify effective interventions for use in everyday settings. Mobile ...

    • Sorterius - An augmented reality app for encouraging outdoor physical activity for people with intellectual disabilities 

      Stellander, Magnus; Henriksen, André; Michalsen, Henriette; Anke, Audny; Ursin, Daniel; Martinez, Santiago; Pelagatti, Susanna; Sato, Keiichi; Haugland, Vebjørn; Johannessen, Erlend; Vidal, Juan Carlos Torrado; Hartvigsen, Gunnar (Chapter; Bokkapittel, 2022-08-22)
      Many with intellectual disabilities (ID) have difficulties adhering to current physical activity guidelines. The goal of this study was to develop a mobile app for assisting people with ID to be more physically active. We implemented a solution that combines the digital and real world using augmented reality (AR). Eight people working with people with ID (special education teachers, social workers, ...
    • Succeeding with prolonged usage ofconsumer-based activity trackers in clinicalstudies: a mixed methods approach 

      Henriksen, André; Sand, Anne-Sofie; Deraas, Trygve Sigvart; Grimsgaard, Sameline; Hartvigsen, Gunnar; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-27)
      <i>Background</i> - Lack of physical activity (PA) is a risk factor for death and non-communicable disease. Despite this, more than one fourth of adults worldwide do not follow PA guidelines. As part of a feasibility study to test a complex intervention for increasing PA, we included a consumer-based activity tracker (AT) as a tool to measure PA outcomes and to track heart rate during exercise ...
    • Ubiquitous digital health-related data: clarification of concepts 

      Johannessen, Erlend; Henriksen, André; Hartvigsen, Gunnar; Horsch, Alexander; Årsand, Eirik; Johansson, Jonas (Chapter; Bokkapittel, 2022-08-22)
      The increased development and use of ubiquitous digital services reinforce the trend where health-related data is generated everywhere. Data usage in different areas introduces different terms for the same or similar concepts. This adds to the confusion of what these terms represent. We aim to provide an overview of concepts and terms used in connection with digital twins and in a healthcare context.
    • User Expectations and Willingness to Share Self-Collected Health Data

    • User preferences for a physical activity chatbot connected to an activity tracker and integrated into a social media platform 

      Larbi, Dillys; Sandsdalen, Helle; Gabarron, Elia; Årsand, Eirik; Henriksen, André (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-22)
      Performing regular physical activity can be challenging. Integrating chatbots with social media platforms and physical activity sensors can potentially increase physical activity. The objective of this study was to identify design preferences for integrating an activity tracker supported chatbot in a social media platform. Norwegian adults (n=120) responded to an ad-hoc online survey. User preferences ...
    • Using cloud-based physical activity data from Google Fit and Apple HealthKit to expand recording of physical activity data in a population study 

      Henriksen, André; Hopstock, Laila Arnesdatter; Hartvigsen, Gunnar; Grimsgaard, Sameline (Journal article; Tidsskriftartikkel, 2017)
      Large population studies are important sources for medical research. These studies are well planned, well organized, and costly. However, people record health data themselves using different sensors, which are mostly unplanned, unorganized and inexpensive. Nevertheless, self-recorded data might be an important supplement to population studies. The question is how to access and use this data. In the ...
    • Using Fitness Trackers and Smartwatches to Measure Physical Activity in Research: Analysis of Consumer Wrist-Worn Wearables 

      Henriksen, André; Mikalsen, Martin Haugen; Woldaregay, Ashenafi Zebene; Muzny, Miroslav; Hartvigsen, Gunnar; Hopstock, Laila Arnesdatter; Grimsgaard, Sameline (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-22)
      Background: New fitness trackers and smartwatches are released to the consumer market every year. These devices are equipped with different sensors, algorithms, and accompanying mobile apps.

    • Using mobile sensors to expand recording of physical activity and increase motivation for prolonged data sharing in a population-based study 

      Henriksen, André; Hartvigsen, Gunnar; Hopstock, Laila Arnesdatter; Grimsgaard, Sameline (Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
      Regularly conducted population cohort studies contribute important new knowledge to medical research. A high participation rate is required in these types of studies in order to claim representativeness and validity of study results. Participation rates are declining worldwide, and re-searchers are challenged to develop new data collection strategies and tools to motivate people to participate. The ...
    • Validity of the Polar M430 Activity Monitor in Free-Living Conditions: Validation Study 

      Henriksen, André; Grimsgaard, Sameline; Horsch, Alexander; Hartvigsen, Gunnar; Hopstock, Laila Arnesdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-16)
      <i>Background</i>: Accelerometers, often in conjunction with heart rate sensors, are extensively used to track physical activity (PA) in research. Research-grade instruments are often expensive and have limited battery capacity, limited storage, and high participant burden. Consumer-based activity trackers are equipped with similar technology and designed for long-term wear, and can therefore ...
