Eekhout, I. (author), van Buuren, S. (author), Visser, B. (author), Bink, M.C.A.M. (author), Huisman, A. (author)Intensive longitudinal data can be used to explore important associations and patterns between various types of inputs and outcomes. Nonlinear relations and irregular measurement occasions can pose problems to develop an accurate model for these kinds of data. This paper focuses on the development, fitting and evaluation of a prediction model...article 2023

Bosch, T. (author), Mathiassen, S.E. (author), Hallman, D. (author), de Looze, M.P. (author), Lyskov, E. (author), Visser, B. (author), van Dieën, J.H. (author)This study investigated temporal changes in movement strategy and performance during fatiguing short-cycle work. Eighteen participants performed six 7-min work blocks with repetitive reaching movements at 0.5 Hz, each followed by a 5.5-min rest break for a total duration of 1 h. Electromyography (EMG) was collected continuously from the upper...article 2012

(author)This study investigated the effect of work pace on workload, motor variability and fatigue during light assembly work. Upper extremity kinematics and electromyography (EMG) were obtained on a cycle-to-cycle basis for eight participants during two conditions, corresponding to "normal" and "high" work pace according to a predetermined time system...article 2011

(author), TNO Kwaliteit van Leven (author)The purpose of this study was to determine whether objective electromyographical manifestations of muscle fatigue develop in the upper trapezius muscle in two assembly tasks involving contractions of different low-intensity levels (8% and 12% MVC) and whether these indications of fatigue are homogeneously distributed across different muscle...article 2009

(author), TNO Kwaliteit van Leven (author)The aim of the study was to investigate the effectiveness of a resistance-training program on muscle strength of the back and neck/shoulder muscles, relative physical workload, muscle fatigue and musculoskeletal discomfort during a simulated assembly and lifting task. Twenty-two workers were randomized over an 8-week resistance-training group,...article 2009

Visser, B. (author), van Dieën, J.H. (author), TNO Kwaliteit van Leven (author)A review of the literature on the pathophysiology of upper extremity muscle disorders (UEMDs) was performed. An overview is given of clinical findings and hypotheses on the pathogenesis of UEMDs. The literature indicates that disorders of muscle cells and limitations of the local circulation underlie UEMDs. However, these disorders identified do...article 2006

(author), TNO Kwaliteit van Leven (author), KvL (author)The object of the current study was to determine whether static contraction of proximal musculature has an effect on the blood flow more distally in the upper extremity. Static contractions of muscles in the neck shoulder region at three levels (relaxed, shoulders elevated and shoulders elevated loaded with 4.95 kg each) were combined with...article 2006

(author), TNO Arbeid (author)This paper presents an overview of theories concerning the development of RSI (repetitive strain injury), related to muscle disorders. Movement is a noisy process. The level of noise is affected by factors such as fatigue and psychosocial stress. In order for precision movements to be made in such situations, an increased level of muscle...article 2005

Visser, B. (author), de Looze, M.P. (author), de Graaff, M.P. (author), van Dieën, J.H. (author)The objective of the present study was to gain insight into the effects of precision demands and mental pressure on the load of the upper extremity. Two computer mouse tasks were used: an aiming and a tracking task. Upper extremity loading was operationalized as the myo-electric activity of the wrist flexor and extensor and of the trapezius...article 2004

(author), TNO Preventie en Gezondheid (author)High precision demands in manual tasks can be expected to cause more selective use of a part of the muscular synergy involved. To test this expectation, load sharing of the index finger and middle finger was investigated during a pinching task. Myoelectric activation of lower arm and neck-shoulder muscles was measured to see if overall level of...article 2003

In veel gevallen wordt geadviseerd in deze pauzes oefeningen te doen. Hoewel oefeningen de doorbloeding van spieren zouden kunnen bevorderen, is ook denkbaar dat vermoeidheid door oefeningen wordt versterkt. Het doel van deze studie was het...article 2001

Visser, B. (author), van Dieën, J.H. (author), Veeger, D. (author), de Looze, M.P. (author), Douwes, M. (author)Force and frequency in manual handling tasks are known risk factors for work related upper arm disorders. Three force levels and three frequencies are used to define the external load in a pinching task. The effects of these external loads on subjective and objective responses are studied. Subjective ratings poorly reflect the levels of external...conference paper 2000
