(author)In wheelchair sports, the use of Inertial Measurement Units (IMUs) has proven to be one of the most accessible ways for ambulatory measurement of wheelchair kinematics. A three-IMU configuration, with one IMU attached to the wheelchair frame and two IMUs on each wheel axle, has previously shown accurate results and is considered optimal for...journal article 2022

De Vette, V.G. (author), Veeger, H.E.J. (author), van Dijk, M.P. (author)More insight into in-field mechanical power in cyclical sports is useful for coaches, sport scientists, and athletes for various reasons. To estimate in-field mechanical power, the use of wearable sensors can be a convenient solution. However, as many model options and approaches for mechanical power estimation using wearable sensors exist, and...review 2022

van Trigt, B. (author), Bouman, F.F. (author), Leenen, Antonius J. R. (author), Hoozemans, Marco J.M. (author), van der Helm, F.C.T. (author), Veeger, H.E.J. (author)Medial elbow overuse injuries are rising in baseball. The external valgus torque magnitude is a possible risk factor for medial elbow injuries. The magnitude on its own cannot explain why one pitcher sustains an injury and another does not. Therefore, the aim of this study is to describe the within-individual external valgus torque variability...journal article 2022

Gurnani, Navin (author), van Deurzen, Derek F.P. (author), Willems, W. Jaap (author), Janssen, Thomas W.J. (author), Veeger, H.E.J. (author)Background: After latissimus dorsi transfer (LDT), an increase in scapulothoracic (ST) contribution in thoracohumeral (TH) elevation is observed when compared to the asymptomatic shoulder. It is not known which shoulder muscles contribute to this change in shoulder kinematics, and whether the timing of muscle recruitment has altered after LDT...journal article 2022

(author)It is generally accepted that most of the energy transferred to the ball during a baseball pitch is generated in the trunk and lower extremities. Therefore, purpose of this study was to assess the energy flow through the lower extremities during a baseball pitch. It was hypothesised that the (stabilising) leading leg mainly transfers energy...journal article 2022

de Vries, Wiebe H.K. (author), Amrein, Sabrina (author), Arnet, Ursina (author), Mayrhuber, Laura (author), Ehrmann, Cristina (author), Veeger, H.E.J. (author)Shoulder problems (pain and pathology) are highly prevalent in manual wheelchair users with spinal cord injury. These problems lead to limitations in activities of daily life (ADL), labor- and leisure participation, and increase the health care costs. Shoulder problems are often associated with the long-term reliance on the upper limbs, and...journal article 2022

Noteboom, L. (author), Hoozemans, Marco J.M. (author), Veeger, H.E.J. (author), van der Helm, F.C.T. (author)Muscle force analysis can be essential for injury risk estimation and performance enhancement in sports like strength training. However, current methods to record muscle forces including electromyography or marker-based measurements combined with a musculoskeletal model are time-consuming and restrict the athlete's natural movement due to...journal article 2022

(author), Bipat, Robbert (author), Vanhees, Luc (author), Buys, Roselien (author)Objectives Home-based physiotherapy interventions to improve post-stroke mobility are successful in high-income countries. These programs require less resources compared to center-based programs. However, feasibility of such an intervention in a low and middle-income setting remains unknown. Therefore, the SunRISe (Stroke Rehabilitation In...journal article 2022

Leenen, A.J.R. (author), van Trigt, B. (author), Hoozemans, M. J.M. (author), Veeger, H.E.J. (author)Background: Baseball pitching performance can be mechanically explained by the summation of speed principle and the principle of optimal coordination of partial momenta. Impeding optimal energy generation or transfer by or between the pelvis and trunk segments could provide valuable insight into possible compensation or catch-up mechanisms...journal article 2022

Gomaz, L. (author), Veeger, H.E.J. (author), van der Graaff, E. (author), van Trigt, B. (author), van der Meulen, F.H. (author)Ball velocity is considered an important performance measure in baseball pitching. Proper pitching mechanics play an important role in both maximising ball velocity and injury-free participation of baseball pitchers. However, an individual pitcher’s characteristics display individuality and may contribute to velocity imparted to the ball. The...journal article 2021

van Trigt, B. (author), Galjee, E.N. (author), Hoozemans, Marco J.M. (author), van der Helm, F.C.T. (author), Veeger, H.E.J. (author)Background: Baseball pitching is associated with a high prevalence of ulnar collateral ligament injuries, potentially due to the high external valgus load on the medial side of the elbow at the instant of maximal shoulder external rotation (MER). In-vitro studies show that external valgus torque is resisted by the ulnar collateral ligament but...journal article 2021

One of these is the ulnar collateral ligament (UCL) injury. In the field of sports injuries, most research focuses on average kinematics and kinetics between subjects, whereas focusing on within-subject variability appears to be more relevant for determining injury risk. We constructed a simple...journal article 2020
