Herrebrugh, T.O. (author)In total knee arthroplasty (TKA) the contact surfaces of the knee are replaced with prosthetic components. In order to fit the prosthetic components, the bones are shaped by making bone cuts. Patient specific surgical guides (PSSGs) are guides made from CT or MRI images to fit the patient’s anatomy. They guide the bone cuts. When bone deviations...master thesis 2015

Pogosian, M. (author)Upper limb amputation causes several functional disabilities and lowers patient’s self body image. At Delft University of Technology the WILMER Open Socket has been developed for below elbow amputees. It allows easy donning and doffing, and minimizes perspiration problems by leaving 75% of the skin uncovered. However, the relative large locking...master thesis 2015

Slob, J.A.E. (author)Currently different technologies are available that help a patient to breath. Two of these technologies are Intermittent Positive Pressure Ventilation (IPPV) and High Frequency Oscillatory (HFO) ventilation. There are no ventilators with HFO functionality on the market that can work without a pressurized gas source. The goal of this research is...master thesis 2015

Karsten, T.C.M. (author)Young women who suffer from cancer have a high change of becoming infertile as a consequence of the treatment. They would benefit from an effective fertility preservation method that allows natural conception. A new method, called autotransplantation of ovarian tissue, has much potential but improvements can be made. The method entails that...master thesis 2015

Van Velzen, B. (author)Atherosclerosis is a progressive arterial disease in which fatty tissue accumulates in the arterial wall. Due to this lipid uptake, the artery thickens and can eventually rupture, causing the lipids to flow into the bloodstream and form blood clots. If this happens in the carotid arteries, which supply the head with oxygenated blood, a stroke...master thesis 2015

Moerman, A.M. (author)In this pilot study, we obtained the peri-prosthetic fibrous membrane of eleven patients undergoing hip revision surgery due to aseptic loosening. We investigated the molecular content of the tissue by real-time PCR (RT-PCR) and the structural properties by histology and confocal microscopy. Atomic force microscopy (AFM) and nanoindentation were...master thesis 2015

De Jong, I.M. (author)For this research a new protocol was developed which acquires rich enough data in terms of position, velocity and accelerations such that all the pasive and active parameters of the agonist and antagonist muscle of the wrist in the newest and for this study expended and adapted neuromuscular model can be accurately estimated. Concluded was that...master thesis 2015

Sotiropoulos, G. (author)With the increase of the life expectancy and the deterioration of the quality of life that neurodegenerative diseases can cause to the patients, they have been receiving more and more attention the last few decades in the developed countries. Two of the leading neurodegenerative diseases are Alzheimer’s Disease and Multiple Sclerosis. In...master thesis 2015

Van den Borne, H.F.A. (author)Orthopaedic surgeons can be assisted by Patient Specific Surgical Guides (PSSGs) during the determination of prostheses’ alignment in joint replacement surgeries. These guides are designed preoperatively – using Magnetic Resonance Imaging (MRI) or Computer Tomography (CT) – to have a matching contact surface with the patient’s bone. This enables...master thesis 2014

Wijntjes, J.D. (author)Bilateral coupling, the synchronized behavior between the upper limbs in time and direction, is a well known movement phenomenon for babies. After the age of 11 months, this coupling is largely inhibited so that each limb can be coordinated individually. For stroke patients however, bilateral coupling tends to return. The goal of this study is...master thesis 2014

Ragnarsdottir, K.L. (author)To allow for efficient and robust gait pattern, humans instantaneously modulate their joint impedance. Lower-limb amputees and patients suffering from neurological diseases partly lack that ability. Therefore, prosthetic and rehabilitative devices have been designed to re- store and repair nominal locomotion. For bio-inspired control of these...master thesis 2014

Spyropoulou, V. (author)Even though maintaining upright quiet stance might be considered by humans as a trivial task, it requires a complex balance control mechanism, in which sensory, nervous and muscle subsystems continuously cooperate and interchange environmental information to stabilize posture. Age, diseases and medication often degrade the related subsystems and...master thesis 2014

Villamar Jorgge, J.A. (author)In the present study, the effect of concentration, osmolality and charge of x-ray contrast agents on their diffusion and equilibrium distribution across different zones of cartilage was investigated. Full-thickness cartilage discs (Ø = 8.5 mm, n = 3) were extracted from healthy equine femoral condyle (n = 2). The diffusion of four different...master thesis 2014

Stroo, J.L. (author)People with neuromuscular diseases request an orthosis close to the body for assistance with their arm movements. This paper proposes a concept for a passive arm support that is close to the body and is based on bending beams. Simulations resulted in the final configuration and dimensions of the beams, optimised to balance an arm. One Carbon...master thesis 2014

Glynou, A. (author)The present project focused on the design and development of a mechanical loading device that allows the convection studies in cartilage within a micro-CT chamber. A plastic-made device was designed and build in order to ensure the successful operation in the micro-CT. Besides that it allowed the monitoring of the tissue material properties by...master thesis 2014

Gudmundsson, K. (author)Despite preventive measures in hospitals through the control of environmental and personnel contamination and systemic administration of antibiotics, implant associated infections (IAIs) still remain a serious ongoing problem for hospitals and patients around the world. The main characteristic of IAIs is that bacteria colonizes the implants...master thesis 2014

Fernando, J.D.L. (author)Titanium surfaces modified by plasma electrolytic oxidation (PEO) have attractive physico-chemical characteristics that may favor osseointegration of bone implants. This study aimed at delineating the effects of PEO topography and surface calcium on the in vitro pre-osteoblasts response. Two different surfaces were generated by varying the...master thesis 2014

Kunst, J.J. (author)The ability of current surgical luminaires to adapt the light field to different wound shapes is very limited. A system that is able to modify the shape of the light field to the actual wound shape should be able to improve the visual performance of the surgeon during a surgical procedure. A luminaire system has been designed that receives an...master thesis 2014

Pietersma, E.B. (author)Musculoskeletal models can be used to distinguish too short or too slow muscles in Cerebral Palsy patients. Therefor muscle-tendon geometry needs to be modeled accurately in order to predict the need and effectiveness of muscle-tendon lengthening. This geometry is strongly related to the location and orientation of the joint centres. In clinic...master thesis 2014
