This paper investigates the effect of intrinsic muscle stiffness on neural control parameters in biological musculoskeletal control of stabilisation or reaching tasks. Current model implementations of intrinsic muscle properties are highly simplified, limiting their accuracy in replicating experimental short-range stiffness (SRS) behaviour,...

Inertial measurement units (IMUs) offer the possibility to capture the lower body kinematics of players of outdoor team sports. However, various sources of error are present when using IMUs: the definition of the body frames, the soft tissue artefact (STA) and the orientation filter. Methods to minimize these errors are currently being used...

Background: Amyotrophic lateral sclerosis (ALS) is a motor neuron disease that is characterized by the degeneration of upper and lower motor neuron (UMN, LMN). A defining feature of ALS is its heterogeneous presentation, with varying sites of disease onset and progression rate. Diagnosing ALS requires the observation of both UMN and LMN...

Injury to the Ulnar Collateral Ligament (UCL) is common among baseball pitchers, due to high external valgus torques applied around the elbow during pitching. Literature shows that elbow muscles and the osseous articulation can lower the load imposed to the UCL by countering the external valgus moment. As the contribution of the individual elbow...

The combination of the high number and the consequences of falls in older adults led to the development of fall risk assessments; non-sensor-based and sensor-based. Multiple studies used ML for older adults' fall risk prediction using raw IMU data. This study's objective was to develop a DL algorithm that predicts the fall risk of people living...

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;...

Short-track speed skates are prepared with rocker to improve cornering behavior. However, rocker also has a negative impact on ice friction. As there is currently no scientific theory for selecting optimal rocker profiles, skaters have to rely on personal experience. There is a lack of experimental data available in literature to validate...

Existing wind load simulators such as wind tunnels and fans have multiple disadvantages, especially when used in a scaled-down environment. This paper proposes to simulate wind loads by using an admittance-controlled industrial robot arm rigidly attached to a research object. Admittance control should make it possible to simulate wind loads and...

Problem: A biomarker that accurately predicts recovery of ischemic stroke for patients with poor baseline Fugl-Meyer Assessment of the Upper Extremity (FMA-UE) is lacking. Biomarkers that predict recovery while providing functional insight into the underlying neural process are highly desired for optimal clinical care. Objectives: This...

Running Specific Prosthesis (RSP) allow amputee sprinters to compare to the best able-bodied sprinters in the world. In RSP research, the current state of the art mainly focusses on highly detailed analysis of discrete moments in the sprint, but more data of the entire sprint process in terms of RSP characteristics and sprinting technique are...

Background Upper limb prostheses help people with an upper limb deficiency in performing activities of daily living. They can be divided into two categories; body-powered and externally powered prostheses. The advantage of body-powered prostheses is that they provide feedback to the user. The advantage of externally powered prostheses is the low...

Introduction: A thigh push-off is often used as a compensation strategy for standing up by elderly people. However, the biomechanics of this movement are not known. In this thesis the standing-up movement with the use of the thigh push-off strategy (TP), the armrest push-off strategy (AR) and the no arm aid strategy (NA) was analysed. The aim...

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...

The design of current skating suits is based on the assumption that the flow across the skater body parts is highly similar to cylinder flow. The latter features drag crisis behaviour, resulting in significant drag reduction at the critical Reynolds number. However, whether the aforementioned assumption is valid and whether a drag crisis along...

Nowadays the design of prosthetic hands is mainly focused on myo-electric control for more functionality. And easy producible 3d printed prosthetics to lower the costs of a custom prosthesis. As a result of this change of focus, the body powered prosthetic hands currently on the market are mainly simple clamping mechanisms with no innovative...

When designing musculoskeletal models for forwardsimulation studies, a tradeoff must be made between biologicalfidelity and computational efficiency. A method is proposedthat optimizes the coordinates of via points of muscle paths,used in relatively simple musculoskeletal models, such that themuscle moment arms match those of more complex...

Temporomandibular disorders (TMD) affect about 5-12 percentage of individuals with consequences such as jaw noises, clicking, myofascial pain, discomfort, limited mandibular range of motion and stress. Treatments depend on the cause and extent of the damage and part of the joint or jaw affected. When exact aetiology of TMD is unclear, generic...

Patients suffering from diseases affecting verbal communication can make use of assistive devices to improve communication. Some severely disabled patients can only produce yes-or-no responses to communicate. These responses can be created through a physical switch, eye blink, or a 'mental' click created by brain activity. The yes-or-no...

Background: When two acoustic sinusoids of slightly different frequencies are presented in the same ear, the listener perceives a beating sound with a rate the difference frequency between the two sinusoids. In the dichotic presentation of two acoustic sinusoids with slightly different frequencies, separately at the two ears, the listener...

Background: The efficacy of a thrombectomy procedure for acute ischaemic stroke (AIS) is largely dependent on mechanical behaviour of thrombi and interactions with the thrombectomy device. Studies have examined clot analogues and evidence suggests that thrombus mechanical properties largely depend on composition, yet evidence based on thrombi...
