van den Heuvel, Gaia (author)Children with cerebral palsy (CP) commonly have bony deformities of the foot, which lead to pain and gait problems. One of the causes of such a deformity is an imbalance in muscle forces around the foot. In turn, the bony deformity can also alter muscle function, due to, for example, altered muscle moment arm lengths. In this study, the altered...master thesis 2023

Balvert, Stephan (author)In this work, we propose a method for monitoring and management of rotator-cuff tendon strains in human-robot collaborative physical therapy for rotator cuff rehabilitation. The proposed approach integrates a complex offline biomechanical model with a collaborative, industrial robot arm and an impedance controller. The model is used for...master thesis 2022

Marbus, Anna (author)The objective of this study is to simulate lumbar stabilization in autonomous vehicles through the utility of OpenSim. Considering sufficient isometric strength is required for dynamic analysis, validity of the full-body model developed by Schmid et al. [43] in isometric conditions is examined first. This encompasses the establishment of maximal...master thesis 2022

Boelens, Jelle (author)The study of human motion consists of the analysis of kinematics, dealing with joint angles, velocities and accelerations, and kinetics, which deals with joint torques and interaction forces. Traditionally, kinematics and kinetics are estimated from optical marker data and sometimes measured interaction forces. Inertial measurement units (IMUs)...master thesis 2022

Zandee, Willem (author)BACKGROUND: Research on the role of patellar biomechanics in patellofemoral (PF) joint pathologies requires accurate and reliable measurement of the patella relative to the femur (patellar tracking) but current methods have limitations. In vivo measurement of PF kinematics is done using medical imaging techniques but these are expensive, involve...master thesis 2022

Verhagen, Joris (author)Humans and other biological bipedal walkers are extraordinarily agile and robust. This is especially apparent when certain features of the environment are unknown such as unexpected downsteps (for example, suddenly walking off the side-walk or not expecting the last stair when descending). Humans can negotiate these downsteps ---both expected...master thesis 2022

Klaver, Jacqueline (author)Hamstring injuries in field hockey are very common. Accurate estimates of muscle tendon unit lengths (MTU) and elongation velocities could give insight into the risk of injury during field hockey specific movements. For accurate measurements the hockey field would be best suited. Inertial measurement technology allows for such measurements;...master thesis 2022

Smit, Nerissa (author)There is an increasing need for transfemoral prostheses that provide gait support, stability, safety and comfort. Although there are many prostheses available in different levels of complexity and price, there is still room for improvement. It has been proved that the cost of transport (CoT) for walking is significantly increased for...master thesis 2022

van den Broek, Annemiek (author)Introduction: Amputees may be eligible to use a socket or osseointegrated (OI) prosthesis after losing a limb. A lot is known about the stump-socket interface in transtibial (TT) amputees. However, there are hardly any articles that explain the load transfers between the tibia and an OI prosthesis. For this reason, this study will focus on the...master thesis 2021

Groenhuis, Jan (author)Introduction During Bicycle Motocross races (BMX SX), the start has been proven to be crucial for good overall performance [1]. Riders reaching the bottom of the eight meter high starting ramp in front of the pack, have a favorable position to perform the first jump and can pick the most ideal line through the first corner. The chances of...master thesis 2021

Siemelink, Iris (author)Background:<br/>Many professional violin players develop pain complaints in neck and shoulder regions as a result of prolonged practices containing highly repetitive motions and awkward postures. These complaints are often diagnosed as overuse syndrome, where physical changes are not apparent and of which the etiology is not yet understood....master thesis 2021

de Vet, Joran (author)Muscle-driven simulations performed with a musculoskeletal model of the human upper-extremity need to include closed-loop kinematics to capture the limb's full mobility and model the actions of thoracoscapular muscles. On the OpenSim platform, a single upper-extremity model with closed-loop kinematics is available: the thoracoscapular shoulder...master thesis 2021

Kiss, Bernadett (author)Various neuromuscular disorders such as spinal cord injury, Charcot-Marie-Tooth disease and poliomyelitis lead to calf muscle weakness, which limits the patient's ability to propel their body forward during gait. Their abnormal gait pattern is characterized by increased ankle dorsiflexion, excessive knee flexion during stance and reduced ankle...master thesis 2021

de Kanter, Daan (author)Inertial Measurement Unit (IMU)-based motion capture has gained interest over the years due to its potential to measure human movement in the clinic and on the sports field at low cost. Still, IMU-based motion reconstruction remains a challenging task as these IMU measurements are corrupted by noise and bias. There have been many filtering and...master thesis 2021

Mackenbach, Caroline (author)Background: In children with cerebral palsy(CP), muscle-tendon structures are altered. While interventions exist to treataltered structures, the selection of the most suitable treatment is verycomplex with highly variable outcomes. Musculoskeletal models have thepotential to support clinical decision making. However, a known...master thesis 2021

Boers, Lars (author)Pathologiessuch as stroke or cerebral palsy are often characterized by excessivemediolateral bending of the trunk. However, it is unclear how mediolateral trunk-sway affects mechanicalwork of more distal joints during gait. We therefore pose the researchquestion: <b>How does increased mediolateraltrunk-sway affect the total...master thesis 2020

Bloks, Bente (author)The ankle plantar flexion muscles are the main contributors to the propulsion of the body during gait. Deficits in these muscles, such as reduced muscle strength, often lead to impaired walking. A characteristic widely observed in gaits arising from various pathologies is an increase in medio-lateral trunk movements. However, this is not yet...master thesis 2020

Kelbling, Jelle (author)The DelFly Nimble is a type of tailless flapping-wing micro air vehicles (FWMAVs) that has received an increasing amount of attention. FWMAVs show efficient and agile flight possibilities at small scale. The aerodynamics and dynamics of these flapping vehicles are challenging and not fully understood. In this work, a strategy to implement a 3D...master thesis 2020

Molenaar, Mitchel (author)Patellar tendinopathy (PT) is a common manifestation in jumping sports characterized by pain and a reduced load bearing capacity. The exact cause of PT has not been determined, which makes it difficult to prevent and treat. A stiffer landing technique might be a risk-factor for PT. Retraining of the landing technique into a less stiffer...master thesis 2020
