Saers, H. (author)Introduction: In the near future space tourism will be a reality. The flights will be suborbital; hyper-gravity, microgravity, heavy vibrations and pressure differences will occur. The physiological effects on the suborbital tourist cannot be sufficiently predicted. All currently available baseline data were collected in a highly selected group...master thesis 2013

Potgieter, S. (author)Stroke is a serious global health care problem for which rehabilitation is the main mode of therapy. Studying human corticomuscular communication with a measure that can reveal causality in a system with sensory and motor pathways has the potential to lead to an optimal, patient-tailored rehabilitation strategy. The goal of this study was to...master thesis 2013

Lobo-Prat, J. (author)Currently, many different control interfaces for the operation of active movement-assistive device exist but their respective performance capabilities and limitations remain unclear. The goal of this study was to quantitatively evaluate the performance and learning characteristics of EMG-, force- and hand joystick-based interfaces. The human...master thesis 2013

Wever, J.W.M. (author)A force illusion device is a portable mechanism that generates the illusion of an external force applied on the device. It has potential applicability as a navigation aid for blind or visually impaired people. Force illusion devices that use a cyclic translating mass to generate the illusion have one drawback. Their users will feel a moment...master thesis 2013

Roels, P.L. (author)Cam impingement appears to be an important factor in the development of early osteoarthritis (OA) of the hip. A Cam is generally diagnosed in young and active adults, already at the age of thirteen. Therefore, it has been suggested that excessive femoral loading during skeletal development might trigger the abnormal morphology. The goal of this...master thesis 2013

Helgadottir, A. (author)Offset muscle activation is the constant neural firing to muscles, even at rest, defining the minimum muscle contraction. Until now, the offset muscle activation has been neglected in the analysis of the dynamical behavior of joints. There is a clinical need for an assessment method to estimate the contribution of the offset muscle activation to...master thesis 2013

Oortwijn, P.T. (author)Vibration in moving mechanisms and manipulators is almost always present due to manufacturing tolerances, assembly errors and non-uniform density of materials. Small errors in parameters such as mass and length may result in a non-balanced mechanism producing shaking forces. Normally a mechanism would be balanced using a trial and error method,...master thesis 2013

Goos, T.G. (author)Very preterm infants need support to survive. This support almost always incorporates respiratory support in the form of pressure and additional oxygen. Since late 2010 multiple resuscitation councils have advised oxygen saturation targets after birth. An observational study was conducted to observe to which extent the European Resuscitation...master thesis 2013

Li, H. (author)Electroencephalograph (EEG) is used in various applications such as diagnosing patients suffering from epilepsy or seizures. Motion artefact is the noise recorded together with the desired biopotential signals. It is mainly introduced by the relative motion between the measurement electrode and the human scalp. Dry electrodes are preferred in...master thesis 2013

Sluiman, J.V. (author)Internationally the health care system is under pressure and research aims to give insights in hospitals’ processes to identify areas where ef?ciency gains can be achieved. At the Rotterdam Eye Hospital a case study is conducted to track the location of patients throughout their hospital visit, collecting data about patients’ processes and...master thesis 2013

Perenboom, M.J.L. (author)In movement control cortical signals are integrated with afferent feedback from reflexes. Disturbed integration is suggested to underlie many movement disorders. Cortical and afferent signals can integrate in the spinal cord and at supraspinal centres, though the exact location and mechanism of integration are unknown yet. The goal of this study...master thesis 2013

Derks, L. (author)Introduction: Paresis in UMND patients leads to immobilization and disuse of the ankle joint. As a result, secondary changes such as increased passive stiffness and plastic CNS rearrangements aggravate the paresis. We propose an intervention that compensates the passive stiffness, enabling the remaining muscle force to initialize movement to...master thesis 2013

Angeluova, G.V. (author)Introduction: Obstetric Brachial Plexus Lesion (OBPL) is characterized by diminished motor and sensory function. These may be worsened by misrouted nerve fibres and faulty formation of central motor programmes. The latter is treated with triceps injections of botulinum toxins, which is aimed at inactivating misrouted nerve fibres in the triceps,...master thesis 2012

Frankenmolle, A.M.M. (author)Parkinson?’s disease (PD) is a progressive neurodegenerative disorder characterized by reduced movement. Postural instability and gait dysfunction (PIGD) is one of the more debilitating symptoms of PD due to its effect on activities of daily life and increased risk for falls. In later stages of the disease, cognitive impairment affects executive...master thesis 2012

Koumans, Y. (author)Abnormal neuromuscular control (NMC) has been suggested as a cause or effect of a-specific low back pain. This study aimed to gain more insight into the stabilization of the low back during postural control by developing a method to study the intrinsic and reflexive components of NMC. Inertial loading of the trunk by perturbation of subjects on...master thesis 2012

Reyes Lua, A.M. (author)The elastic strain limit of the tendon appears to be an omnipresent parameter in the literature in many of the problems described related to its pathologic conditions, which are often related to the repetitive loading tendons undergo during life. In other words, the study of the fatigue resistance of the tendons may provide information about the...master thesis 2012

Terzopoulos, V. (author)Every year fifteen million infants are born prematurely in the whole world. The maturation of the brain occurs mainly during the third trimester (24-40 weeks of gestational age). Therefore extremely preterm infants (infants born before 25 weeks of gestational age) are vulnerable to brain injuries (perinatal asphyxia and perinatal stroke being...master thesis 2012

Borleffs, M.S. (author)Worldwide yearly 800.000-1.000.000 people receive a total artificial hip. 8-9% Of all patients requires a second surgery to correct the primary arthroplasty. In more than 70% of cases, aseptic loosening is the cause for implant failure. Possible pathways leading to aseptic loosening are stress shielding and micro-motions. Stress shielding can be...master thesis 2012

Geers, A.M. (author)The goal of this study was to assess if the superposition principle is valid in head-neck stabilization during combined torso perturbations and continuous galvanic vestibular stimulation. Nine seated subjects were perturbed in lateral direction on a motion platform while GVS was simultaneously applied. Both the mechanical and galvanic input...master thesis 2012

Cuschieri, M. (author)Nowadays, drug eluting stents (DES) are the treatment of choice for de novo atherosclerotic lesions. Novel DES are shifting to polymer-free (PF) drug delivery in order to avoid the problem of late stent thrombosis associated with long term polymer presence in the vessel lumen. The scope of this study was to assess the potential of a microporous...master thesis 2012
