(author)urpose: Postural control deteriorates with age, especially under dual-task conditions. It is currently unknown how a challenging virtual reality weight-shifting task affects lower back muscle activity. Hence, this study investigated erector spinae neuromuscular control during mediolateral weight-shifting as part of an exergame during single- (ST...article 2023

de Vries, A.W. (author), Murphy, M. (author), Könemann, R. (author), Kingma, I. (author), de Looze, M. (author)Occupational Applications. Our study quantified the extent of support provided by a passive arm-support exoskeleton throughout a range of postures. Mechanical support generated by the arm-support exoskeleton (SkelEx, Rotterdam, The Netherlands) that we tested clearly reaches its maximum at elevation angles ranging from 60° to 120°, where the...article 2019

Koldijk, S. (author), Neerincx, M.A. (author), Kraaij, W. (author)Employees often report the experience of stress at work. In the SWELL project we investigate how new context aware pervasive systems can support knowledge workers to diminish stress. The focus of this paper is on developing automatic classifiers to infer working conditions and stress related mental states from a multimodal set of sensor data ...article 2018

Hiemstra-Van Mastrigt, S. (author), Groenesteijn, L. (author), Vink, P. (author), Kuijt-Evers, L.F.M. (author)This literature review focused on passenger seat comfort and discomfort in a human-product-context interaction. The relationships between anthropometric variables (human level), activities (context level), seat characteristics (product level) and the perception of comfort and discomfort were studied through mediating variables, such as body...article 2017

Ly, V. (author), Roijendijk, L.L.M. (author), Hazebroek, H. (author), Tonnaer, C. (author), Hagenaars, M.A. (author)Freezing is a defensive response to acute stress that is associated with coping and alterations in attentional processing. However, it remains unclear whether individuals in high risk professions, who are skilled at making rapid decisions in emergency situations, show altered threat-induced freezing. Here we investigated the effect of incident...article 2017

Hiemstra-Van Mastright, S. (author), Meyenborg, I. (author), Hoogenhout, M. (author)BACKGROUND: Discomfort increases when duration of sitting is longer. Aircraft passengers are subjected to prolonged sitting in restricted postures, which can cause discomfort. OBJECTIVE: To examine the relationship between duration of sitting and development of discomfort, as well as the influence of different passenger activities. METHODS:...article 2016

Coenen, P. (author), Douwes, M. (author), van den Heuvel, S. (author), Bosch, T. (author)Occupational postures are considered to be an important group of risk factors for musculoskeletal pain. However, the exposure-outcome association is not clear yet. Therefore, we aimed to determine the exposure-outcome association of working postures and musculoskeletal symptoms. Also, we aimed to establish exposure limits for working postures....article 2016

Lubeck, A.J.A. (author), Bos, J.E. (author), Stins, J.F. (author)Effects of visual roll-motion on postural sway and the subjective visual vertical (SVV) often is studied using mechanical devices, whereas electronic displays offer cheaper and more flexible alternatives. These devices typically emit and reflect light scattered by the edges of the screen, providing Earth-fixed cues of verticality. These cues may...article 2016

Lubeck, A.J.A. (author), Bos, J.E. (author), Stins, J.F. (author)Objective : Visually induced motion sickness (VIMS) and increased postural sway are two adverse side effects that may occur when viewing motion stimuli. However, whether these effects are elevated to a greater extent when viewing stereoscopic 3D motion stimuli, compared to 2D stimuli on a TV screen, has not been investigated under controlled...article 2016

(author)Increasing evidence is being found for the association of health risk factors with work-related physical inactivity. An increasing number of people are being exposed to this form of inactivity, and as a result, various interventions aimed at increasing physical activity during working hours are being developed. This study aims to investigate the...article 2016

Bernaards, C. (author), Hildebrandt, V.H. (author), Hendriksen, I.J. (author)Background. Evidence shows that prolonged sitting is associated with an increased risk of mortality, independent of physical activity (PA). The aim of the study was to identify correlates of sedentary time (ST) in different age groups and day types (i.e. school-/work day versus non-school-/non-work day). Methods. The study sample consisted of...article 2016

Lubeck, A.J.A. (author), Bos, J.E. (author), Stins, J.F. (author)Abstract Objective It is generally assumed that motion in motion images is responsible for increased postural sway as well as for visually induced motion sickness (VIMS). However, this has not yet been tested. To that end, we studied postural sway and VIMS induced by motion and still images. Method 15 Participants were exposed to motion- and...article 2015

Hiemstra-van Mastrigt, S. (author), Kamp, I. (author), van Veen, S.A.T. (author), Vink, P. (author), Bosch, T. (author)New technologies have led to an increasingly sedentary lifestyle. Sedentary behaviour is characterised by physical inactivity and is associated with several health risks. This excessive sitting does not only take place in the office or at home, but also during daily commute. Therefore, BMW AG developed an active seating system for the back seat...article 2015
