De Winter, J.C.F. (author), Dodou, D. (author)Function allocation is a core activity of the human–machine systems discipline. Sixty years ago, Paul Fitts marked the outset of function allocation research with an 11-statements list. Since then numerous function allocation methods have been proposed, but strikingly the seminal Fitts list spans the entire history of this domain and continues...journal article 2011

Horeman, T. (author), Rodrigues, S.P. (author), Van den Dobbelsteen, J.J. (author), Jansen, F.W. (author), Dankelman, J. (author)Background - To improve endoscopic surgical skills, an increasing number of surgical residents practice on box or virtual reality (VR) trainers. Current training is focused mainly on hand–eye coordination. Training methods that focus on applying the right amount of force are not yet available. Methods - The aim of this project is to develop a...journal article 2011

Dunning, A.G. (author), Tolou, N. (author), Herder, J. (author)For many applications in precision engineering, a six degrees of freedom (DoF) compliant stage (CS) with zero stiffness is desirable, to deal with problems like backlash, friction, lubrication, and at the same time, reduce the actuation force. To this end, the compliant stage (also known as compliant mechanism) can be statically balanced with a...journal article 2011

(author)Background: In the light of both the importance and large numbers of case series and cohort studies (observational studies) in orthopaedic literature, it is remarkable that there is currently no validated measurement tool to appraise their quality. A Delphi approach was used to develop a checklist for reporting quality, methodological quality...journal article 2011

Wolterbeek, N. (author), Nelissen, R.G.H.H. (author), Valstar, E.R. (author)Purpose: The aim of this study was to compare a broad range of total knee prostheses with different design parameters to determine whether in vivo kinematics was consistently related to design. The hypothesis was that there are no clear recognizable differences in in vivo kinematics between different design parameters or prostheses. Methods: At...journal article 2011

De Vlugt, E. (author), Van Eesbeek, S. (author), Baines, P. (author), Hilte, J. (author), Meskers, C.G.M. (author), De Groot, J.H. (author)Muscles behave as elastic springs during the initial strain phase, indicated as short range stiffness (SRS). Beyond a certain amount of strain the muscle demonstrates a more viscous behavior. The strain at which the muscle transits from elastic- to viscous-like behavior is called the elastic limit and is believed to be the result of breakage of...journal article 2011

Forbes, P.A. (author), Happee, R. (author), Van der Helm, F.C.T. (author), Schouten, A.C. (author)Force and position perturbations are widely applied to identify muscular and reflexive contributions to posture maintenance of the arm. Both task instruction (force vs. position) and the inherently linked perturbation type (i.e., force perturbations-position task and position perturbations-force tasks) affect these contributions and their mutual...journal article 2011

Kragten, G.A. (author)There is an emerging need to apply adaptive robotic hands to substitute humans in dangerous, laborious, or monotonous work. The state-of-the-art robotic hands cannot fulfill this need, because they are expensive, hard to control and they consist of many vulnerable motors and sensors. It is aimed to develop simple, adaptive hands that are capable...doctoral thesis 2011

Mugge, W. (author)Complex Regional Pain Syndrome (CRPS) is a disabling syndrome associated with sensory (e.g., burning pain, allodynia, hyperalgesia), autonomic (e.g., edema, skin color and temperature changes), and motor impairments (e.g., tremor, myoclonus, dystonia). Approximately 25% of the patients with CRPS develop fixed dystonia which is characterized by...doctoral thesis 2011

Asadi Nikooyan, A. (author)Detailed information about muscle forces in the human musculoskeletal system are highly demanded for several applications. Unfortunately, the measurement of muscle forces in-vivo is hardly possible. To date, musculoskeletal models are best alternative for the direct measurement of these forces. A major concern in musculoskeletal modeling is,...doctoral thesis 2011

Reilingh, M.L. (author), Tuijthof, G.J.M. (author), Van Dijk, C.N. (author), Blankevoort, L. (author)Background: Malalignment of the hindfoot can be corrected with a calcaneal osteotomy (CO). A well-selected osteotomy angle in the sagittal plane will reduce the shear force in the osteotomy plane while walking. The purpose was to determine the presence of a relationship between the foot geometry and loading of the calcaneus, which influences the...journal article 2011

(author)Background: Complex regional pain syndrome (CRPS) may occur after trauma, usually to one limb, and is characterized by pain and disturbed blood flow, temperature regulation and motor control. Approximately 25% of cases develop fixed dystonia. Involvement of dysfunctional GABAergic interneurons has been suggested, however the mechanisms that...journal article 2011

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

D'Amelio, V. (author), Chmarra, M.K. (author), Tomiyama, T. (author)Developing multi-disciplinary products presents cross-disciplinary problems that are difficult to predict and to solve. Unfortunately, those cross-disciplinary problems are often discovered only at a later stage of the design through physical prototypes and can lead to modification of the conceptual design of a product. This is extremely costly...journal article 2011
