Jannink, M.J.A. (author), Erren-Wolters, C.V. (author), De Kort, A.C. (author), Van der Kooij, H. (author)This paper describes an electric scooter simulation program and a first evaluation study in which we explored if it is possible to train the driving skills of future users of electric mobility scooters by means of an electric scooter simulation program in addition to conventional electric scooter training. Within this explorative study, 10...journal article 2008

Mugge, W. (author), Abbink, D.A. (author), Schouten, A.C. (author), Dewald, J.P.A. (author), Van der Helm, F.C.T. (author)This study aims to quantify the separate contributions of muscle force feedback, muscle spindle activity and co-contraction to the performance of voluntary tasks (‘‘reduce the influence of perturbations on maintained force or position’’). Most human motion control studies either isolate only one contributor, or assume that relevant reflexive...journal article 2009

Van den Wijngaard, J.P.H.M. (author), Kolyva, C. (author), Siebes, M. (author), Dankelman, J. (author), Van Gemert, M.J.C. (author), Piek, J.J. (author), Spaan, J.A.E. (author)The subendocardium is most vulnerable to ischemia, which is ameliorated by relaxation during diastole and increased coronary pressure. Recent clinical techniques permit the measuring of subendocardial perfusion and it is therefore important to gain insight into how measurements depend on perfusion conditions of the heart. Using data from...journal article 2008

(author), Arendzen, J.H. (author), Meskers, C.G.M. (author)Background Spastic paresis in cerebral palsy (CP) is characterized by increased joint stiffness that may be of neural origin, i.e. improper muscle activation caused by e.g. hyperreflexia or non-neural origin, i.e. altered tissue viscoelastic properties (clinically: “spasticity” vs. “contracture”). Differentiation between these components is hard...journal article 2013

(author)Background Resuscitation at birth with 100% oxygen is known to increase the oxidative burden with concomitant deleterious effects. Although fractions of inspired oxygen (FiO2)?<?100% are widely used in preterm infants, starting resuscitation at a (too) low FiO2 may result in hypoxia. The objective of this study is to compare the safety and...journal article 2012

Stano, P. (author), Klinovaja, J. (author), Braakman, F.R. (author), Vandersypen, L.M.K. (author), Loss, D. (author)We investigate theoretically the long-distance coupling and spin exchange in an array of quantum dot spin qubits in the presence of microwaves. We find that photon-assisted cotunneling is boosted at resonances between photon and energies of virtually occupied excited states and show how to make it spin selective. We identify configurations that...journal article 2015

Wauben, L.S.G.L. (author), Albayrak, A. (author), Dols, N. (author), Goossens, R.H.M. (author), IJzermans, J. (author)In 2010 ontvingen 865 Nederlanders die lijden aan chronisch nierfalen een nieuwe nier. Maar er wachten nog steeds 892 patiënten op een donornier en ongeveer 1275 dialysepatiënten sterven elk jaar. Levende-nierdonatie lijkt een geschikte optie om het donortekort te verminderen. Hierbij staat een ‘gezond’ familielid (maar soms ook een anonieme...journal article 2013

Natenstedt, J. (author), Kok, A.C. (author), Dankelman, J. (author), Tuijthof, G.J.M. (author)Articular cartilage has limited regeneration capacities. One of the factors that appear to affect the in vitro cultivation of articular cartilage is mechanical stimulation. So far, no combination of parameters has been identified that offers the best results. The goal is to review the literature in search of the best available set of...journal article 2015

Smit, G. (author), Plettenburg, D.H. (author), Van der Helm, F.C. (author)The goal of this study was to find an efficient method of energy transmission for application in an anthropomorphic underactuated body-powered (BP) prosthetic hand. A pulley-cable finger and a hydraulic cylinder finger were designed and tested to compare the pulley-cable transmission principle with the hydraulic cylinder transmission principle....journal article 2014

Ozmen, N. (author), Dapp, R. (author), Zapf, M. (author), Gemmeke, H. (author), Ruiter, N.V. (author), Van Dongen, K.W.A. (author)Ultrasound is frequently used to evaluate suspicious masses in breasts. These evaluations could be improved by taking advantage of advanced imaging algorithms, which become feasible for low frequencies if accurate knowledge about the phase and amplitude of the wave field illuminating the volume of interest is available. In this study, we compare...journal article 2015

Arnet, U. (author), Van Drongelen, S. (author), Van de Woude, L.H.V. (author), Veeger, H.E.J. (author)Background The manual wheelchair user population experiences a high prevalence of upper-limb injuries, which are related to a high load on the shoulder joint during activities of daily living, such as handrim wheelchair propulsion. An alternative mode of propulsion is handcycling, where lower external forces are suggested to be applied to reach...journal article 2012

Dankelman, J. (author)With the introduction of minimally invasive surgery (MIS), it became necessary to develop training methods to learn skills outside the operating room. Several training simulators have become commercially available, but fundamental research into the requirements for effective and efficient training in MIS is still lacking. Three aspects of...journal article 2007

(author)Background Instead of hyper-reflexia as sole paradigm, post-stroke movement disorders are currently considered the result of a complex interplay between neuronal and muscular properties, modified by level of activity. We used a closed loop system identification technique to quantify individual contributors to wrist joint stiffness during an...journal article 2009

Van der Kooij, H. (author), Campbell, A.D. (author), Carpenter, M.G. (author)The different measures used to characterize postural sway are sensitive to variations in sampling duration, yet there remains marked variability and a lack of consistency in this temporal parameter when compared between studies. We investigated the effect of sampling duration on 22 commonly used frequency and time domain measures and stabilogram...journal article 2011

Schuurmans, J. (author), Van der Helm, F.C.T. (author), Schouten, A.C. (author)During posture control, reflexive feedback allows humans to efficiently compensate for unpredictable mechanical disturbances. Although reflexes are involuntary, humans can adapt their reflexive settings to the characteristics of the disturbances. Reflex modulation is commonly studied by determining reflex gains: a set of parameters that quantify...journal article 2010

(author)Children with cerebral palsy frequently experience foot dragging and tripping during walking due to a lack of adequate knee flexion in swing (stiff-knee gait). Stiff-knee gait is often accompanied by an overly flexed knee during stance (crouch gait). Studies on stiff-knee gait have mostly focused on excessive knee muscle activity during (pre...journal article

(author)Background: Articular cartilage has very limited intrinsic regenerative capacity, making cell-based therapy a tempting approach for cartilage repair. Cell tracking can be a major step towards unraveling and improving the repair process of these therapies. We studied superparamagnetic iron oxides (SPIO) for labeling human bone marrow-derived...journal article 2011
