Gevolgen van robotisering voor arbeidsbelasting en het arbeidsdeskundig handelen

Douwes, M. (author), Huysmans, M.A. (author), de Looze, M.P. (author), Kraan, K.O. (author)

De robotisering van arbeid voltrekt zich snel. Er verdwijnen banen, maar er veranderen nog veel meer banen. ‘Binnen banen’ nemen robots en ICT-systemen een gedeelte van de waarnemings-, denk- en beslis-, en uitvoeringstaken van ons over. Dit betekent een ver-schuiving in de menstaken en daardoor een verschuiving in arbeidsbelasting. Het AKC...

Eijckelhof, B.H.W. (author), Bruno Garza, J.L. (author), Huysmans, M.A. (author), Blatter, B.M. (author), Johnson, P.W. (author), van Dieën, J.H. (author), van der Beek, A.J. (author), Dennerlein, J.T. (author)

Objective Office workers with high levels of overcommitment and low levels of reward are thought to be more prone to arm-wrist-hand symptoms, possibly through a higher internal physical exposure. The aim of this study was to examine the effects of high overcommitment and low reward on (i) forearm muscle activity, (ii) wrist posture and...

This study, a part of the PRedicting Occupational biomechanics in OFfice workers (PROOF) study, investigated whether there are differences in field-measured forces, muscle efforts, postures, velocities and accelerations across computer activities. These parameters were measured continuously for 120 office workers performing their own work for...

The goal of the present study, a part of the PROOF (Predicting Occupational biomechanics among OFfice workers) study, was to determine if there was a relationship between psychosocial stress, measured by reward and over-commitment, and trapezius muscle activity while workers performed their own computer work in the field. We observed that...

Effects of four types of non-obtrusive feedback on computer behaviour, task performance and comfort

de Korte, E.M. (author), Huysmans, M.A. (author), de Jong, A.M. (author), van de Ven, J.G.M. (author), Ruijsendaal, M. (author)

This study investigated the effects of non-obtrusive feedback on continuous lifted hand/finger behaviour, task performance and comfort. In an experiment with 24 participants the effects of two visual and two tactile feedback signals were compared to a no-feedback condition in a computer task. Results from the objective measures showed that all...

Huysmans, M.A. (author), Hoozemans, M.J.M. (author), van der Beek, A.J. (author), de Looze, M.P. (author), van Dien, J.H. (author)

The authors investigated how tracking performance, submovement organization, pen pressure and muscle activity in forearm and shoulder muscles were affected by target size in a 2D tracking task performed with a pen on a digitizer tablet. Twenty-six subjects took part in an experiment, in which either a small dot or a large dot was tracked, while...

Richter, J.M. (author), van den Heuvel, S.G. (author), Huysmans, M.A. (author), van der Beek, A.J. (author), Blatter, B.M. (author)

Objective Epidemiologic studies on physical exposure during computer use have mainly focused on average exposure duration. In this study, we aimed to relate periods of high peak exposure during computer use with the occurrence of neck-shoulder (NS) and arm-wrist-hand (AWH) symptoms. Methods A prospective cohort study among 1951 office workers...

Objectives: In both science and media, the adverse effects of a long duration of computer use at work on musculoskeletal health have long been debated. Until recently, the duration of computer use was mainly measured by self-reports, and studies using more objective measures, such as software-recorded computer duration, were lacking. The...

Fatigue effects on tracking performance and muscle activity

It has been suggested that fatigue affects proprioception and consequently movement accuracy, the effects of which may be counteracted by increased muscle activity. To determine the effects of fatigue on tracking performance and muscle activity in the M. extensor carpi radialis (ECR), 11 female participants performed a 2-min tracking task with a...
