Plettenburg, S. G.J. (author), Hoppe, T. (author), van der Heijden, H.M.H. (author), Elsinga, M.G. (author)In 2015 the Housing Act was revised in order to further regulate the social housing sector in the Netherlands and thereby improve the steering possibilities for the central government to coordinate housing associations. This included local performance agreements for social housing policy obtaining a legal status. By introducing this policy...journal article 2021

Cuellar Lopez, J.S. (author), Plettenburg, D.H. (author), Zadpoor, A.A. (author), Breedveld, P. (author), Smit, G. (author)Various upper-limb prostheses have been designed for 3D printing but only a few of them are based on bio-inspired design principles and many anatomical details are not typically incorporated even though 3D printing offers advantages that facilitate the application of such design principles. We therefore aimed to apply a bio-inspired approach...journal article 2021

Bos, R.A. (author), Nizamis, Kostas (author), Koopman, Bart F.J.M. (author), Herder, J.L. (author), Sartori, Massimo (author), Plettenburg, D.H. (author)With recent improvements in healthcare, individuals with Duchenne muscular dystrophy (DMD) have prolonged life expectancy, and it is therefore vital to preserve their independence. Hand function plays a central role in maintaining independence in daily living. This requires sufficient grip force and the ability to modulate it with no...journal article 2020

Cuellar Lopez, J.S. (author), Smit, G. (author), Breedveld, P. (author), Zadpoor, A.A. (author), Plettenburg, D.H. (author)In developing countries, the access of amputees to prosthetic devices is very limited. In a way to increase accessibility of prosthetic hands, we have recently developed a new approach for the design and 3D printing of non-assembly active hand prostheses using inexpensive 3D printers working on the basis of material extrusion technology. This...journal article 2019

Hichert, M. (author), Abbink, D.A. (author), Vardy, A.N. (author), van der Sluis, Corry K. (author), Janssen, Wim G.M. (author), Brouwers, Michael A.H. (author), Plettenburg, D.H. (author)Operating a body-powered prosthesis can be painful and tiring due to high cable operation forces, illustrating that low cable operation forces are a desirable design property for body-powered prostheses. However, lower operation forces might negatively affect controllability and force perception, which is plausible but not known. This study...journal article 2019

Bos, R.A. (author), Plettenburg, D.H. (author), Herder, J.L. (author)While designing a dynamic hand orthosis to assist during activities of daily living, the designer has to know whether a concept will have sufficient grasp performance to support these activities. This is often estimated by measuring the interaction force at the contact interface. However, this requires a prototyping step and limits the...journal article 2019

Hichert, M. (author), Vardy, A.N. (author), Plettenburg, D.H. (author)Background: Body-powered prostheses require cable operation forces between 33 and 131 N. The accepted upper limit for fatigue-free long-duration operation is 20% of a users’ maximum cable operation force. However, no information is available on users’ maximum force. Objectives: To quantify users’ maximum cable operation force and to relate...journal article 2018

Hichert, M. (author), Plettenburg, D.H. (author)Background: Body-powered prosthesis users frequently complain about the poor cosmesis and comfort of the traditional shoulder harness. The Ipsilateral Scapular Cutaneous Anchor System offers an alternative, but it remains unclear to what extent it affects the perception and control of cable operation forces compared to the traditional shoulder...journal article 2017

Bos, R.A. (author), Plettenburg, D.H. (author)The addition of a cosmetic glove to an upper limb prosthesis has a distinct effect on the cosmetic value, but its viscoelastic behaviour adds a substantial amount of stiffness and hysteresis to the system. As a result, the overall usability of the prosthesis is degraded. A novel negative stiffness element is designed to compensate for the...journal article 2017

Hichert, M. (author), Abbink, D.A. (author), Kyberd, P.J. (author), Plettenburg, D.H. (author)Background It is generally asserted that reliable and intuitive control of upper-limb prostheses requires adequate feedback of prosthetic finger positions and pinch forces applied to objects. Bodypowered prostheses (BPPs) provide the user with direct proprioceptive feedback. Currently available BPPs often require high cable operation forces,...journal article 2017

Huinnk, L.H.B. (author), Bouwsema, H. (author), Plettenburg, D.H. (author), van der Sluis, C.K. (author), Bongers, R.M. (author)Background: Little is known about action-perception learning processes underlying prosthetic skills in body-powered prosthesis users. Body-powered prostheses are controlled through a harness connected by a cable that might provide for limited proprioceptive feedback. This study aims to test transfer of training basic tasks to functional tasks...journal article 2016

(author)The development of dynamic hand orthoses is a fast-growing field of research and has resulted in many different devices. A large and diverse solution space is formed by the various mechatronic components which are used in these devices. They are the result of making complex design choices within the constraints imposed by the application, the...journal article 2016

Smit, G. (author), Plettenburg, D.H. (author), Van der Helm, F.C.T. (author)Rejection rates of upper limb prostheses are high (23-45%). Amputees indicate that the highest design priority should be reduction of the mass of the prosthetic device. Despite all efforts, the mass of the new prosthetic hands is 35-73% higher than that of older hands. Furthermore current hands are thicker than a human hand, they operate slower...journal article 2014

Smit, G. (author), Plettenburg, D.H. (author)Current articulating electric and body-powered hands have a lower pinch force (15–34 N) than electric hands with stiff fingers (55–100 N). The cosmetic glove, which covers a hand prosthesis, negatively affects the mechanical efficiency of a prosthesis. The goal of this study is to mechanically compare polyvinylchloride (PVC) and silicone...journal article 2013

Herder, J.L. (author), Cool, J.C. (author), Plettenburg, D.H. (author)For cosmetic reasons, hand prostheses are provided with cosmetic gloves. Their pleasing appearance, however, is accompanied by poor mechanical behavior, resulting in a negative influence on prosthesis operation. Glove stiffness is high and nonlinear, and internal friction in the glove material causes energy dissipation (hysteresis). In this...journal article 1998
