Heijs, Floor (author)Background: Knee Osteoarthritis (KOA) is the predominant form of osteoarthritis, and its incidence is anticipated to rise due to an ageing and increasingly overweight population. Altering the Foot Progression Angle (FPA) has demonstrated potential in mitigating the progression of KOA. Wearable feedback methods, especially those utilising single...master thesis 2023

Çetindağ, Can (author)Active knee prostheses are potent in assisting users, providing symmetry in walking, reducing metabolic costs, and preventing long-term health problems. The heart of their complex control algorithm employs the Impedance Control (IC) Law, which controls the torque output of the device by three parameters: stiffness coefficient, equilibrium angle,...master thesis 2023

Vallery, H. (author), Lachmann, F. (author), van der Helm, S.G. (author), Pennycott, A. (author), Smit, G. (author)Standing up using one leg is a challenging task for those with a transfemoral amputation, particularly for elderly users with a low activity level. Active prostheses are generally not accessible to this group and available passive prostheses do not support standing up. This article presents the design and evaluation of the “Energy Restoring...journal article 2023

Wildöer, David (author)To better understand and predict osteoarthritis, researchers are developing so-called coupled modelling workflows. Coupled workflows convert data from gait analysis studies to subject-specific tissue mechanical response estimations through the use of musculoskeletal and finite element models. The tissue mechanical response inside the joint is...master thesis 2022

Gevers, Imke (author)Background: Radiostereometric analysis (RSA) is a technique to assess early migration, which has a predictive value for early failure of unicompartmental knee arthroplasty (UKA). To successfully analyze the RSA images it is important to have a sufficient amount of visiblemarkers with an acceptable three-dimensional distribution.<br/>Objective:...master thesis 2022

(author), Van Asseldonk, Edwin H.F. (author)Knowledge on joint impedance during walking in various conditions is relevant for clinical decision-making and the development of robotic gait trainers, leg prostheses, leg orthotics and wearable exoskeletons. Whereas ankle impedance during walking has been experimentally assessed, knee and hip joint impedance during walking have not been...journal article 2022

(author), Hall, Michelle (author), Dekker, Joost (author), Lems, Willem F. (author), Harlaar, J. (author), van der Esch, Martin (author)Background: Muscle weakness is characteristic of knee osteoarthritis. Muscle steadiness may be an important adjunct to knee muscle strength in improving physical function in knee osteoarthritis. However, the role of muscle steadiness is uncertain. Aims: To determine the associations of knee extensor muscle steadiness with maximal voluntary...journal article 2022

(author)Background: Gait adaptability is of utmost importance for keeping balance during gait in patients with knee osteoarthritis, also after total knee arthroplasty (TKA). The aims of this explorative study are: (1) assess the effect of age, knee osteoarthritis and TKA on gait adaptability; (2) assess changes in gait adaptability pre-to post-TKA...journal article 2022

Vasileiou, Christos (author)Tendon-driven soft exosuits have gained much attention in recent years due to their ability to support people with mobility problems during daily life activities. A task that is particularly assisted by such robotic systems, due to its challenging nature, is stair climbing. However, assisting foot clearance during the swing phase of stair...master thesis 2021

Lopez Hidalgo, Jose (author)Every year, nearly five million people undergo knee, making it one of the most common orthopaedic procedures. Sport-related injuries and age-related diseases are the major causes that lead to a knee operation. To recover mobility, stability and muscle strength, the person must go through a post-surgical rehabilitation program.<br/>The price of...master thesis 2021

Schrijvers, Jim C. (author), van den Noort, Josien C. (author), van der Esch, Martin (author), Harlaar, J. (author)Knee joint instability is frequently reported by patients with knee osteoarthritis (KOA). Objective metrics to assess knee joint instability are lacking, making it difficult to target therapies aiming to improve stability. Therefore, the aim of this study was to compare responses in neuromechanics to perturbations during gait in patients with...journal article 2021

(author), van der Esch, Martin (author)Background: Patients with knee osteoarthritis can adapt their gait to unload the most painful knee joint in order to try to reduce pain and improve physical function. However, these gait adaptations can cause higher loads on the contralateral joints. The aim of the study was to investigate the interlimb differences in knee and hip frontal...journal article 2021

(author)Background: The foot progression angle is an important measure used to help patients reduce their knee adduction moment. Current measurement systems are either lab-bounded or do not function in all environments (e.g., magnetically distorted).

(author)Background: After total knee replacement (TKR) some patients report low self-perceived function, which is clinically measured using patient reported outcome measures (PROMs). However, PROMs, e.g. the Oxford Knee Score (OKS), inherently lack objective parameters of knee function. Biomechanical gait analysis is an objective and reliable...journal article 2021

Palm, Christine (author)Misalignment in prosthetic legs can lead to bad posture, back pain and stump problems. A big influence therein is the alignment in the frontal and transverse plane of a prosthetic knee. This work aims to create an auxiliary tool for the prosthetist to align the prosthesis in an optimal way for the patient, with the use of inertial sensors. The...master thesis 2020
