Wheelchair tennis is one of the fastest growing paralympic sports. An important part in wheelchair sports is classification, which is why the International Tennis Federation is constantly assessing the current classification requirements. The purpose of this study is to assess the relationship between …

Inertial measurement units (IMUs) allow for measurements of kinematic movements outside the laboratory, persevering the athlete-environment relationship. To use IMUs in a sport-specific setting, it is necessary to validate sport-specific movements. The aim of this study was to assess the concurrent validity …

Kinetic Analysis B.V. voert uitgebreide bewegingsanalyses uit bij atleten uit verschillende sporten zoals, atletiek en hockey. Deze analyses worden gedaan aan de hand van inertial measurement units (IMU’s), hierdoor kan de bewegingsuitslag van gewrichten van een atleet gemeten worden. Door dit in kaart …

Wearable inertial sensors (WIS) facilitate the preservation of the athlete-environment relationship by allowing measurement outside the laboratory. WIS systems should be validated for team sports movements before they are used in sports performance and injury prevention research. The aim of the present …

Modifiable (biomechanical and neuromuscular) anterior cruciate ligament (ACL) injury risk factors have been identified in laboratory settings. These risk factors were subsequently used in ACL injury prevention measures. Due to the lack of ecological validity, the use of on-field data in the ACL injury …

BACKGROUND: Physical activity may be both a risk and protective factor for falls and fall-related fractures. Despite its positive effects on muscle and bone health, physical activity also increases exposure to situations where falls and fractures occur. This paradox could possibly be explained by frailty …

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 …

This paper evaluates a design procedure which is able to scale one-dimensional quadratic-residue diffusers, with integrated Helmholtz resonators. These acoustic structures can be tuned to room modes while fitting within a specified volume. An algorithmic solver is used to control geometric parameters …

In sports, inertial measurement units are often used to measure the orientation of human body segments. A Madgwick (MW) filter can be used to obtain accurate inertial measurement unit (IMU) orientation estimates. This filter combines two different orientation estimates by applying a correction of the …

Het objectiveren van de bewegingsuitslag (ROM) in gewrichten is een belangrijk onderdeel binnen de fysiotherapie. Het meest gebruikte valide meetinstrument, de goniometer, is onhandig in het gebruik waardoor vaak gekozen wordt voor een visuele inschatting welke erg onbetrouwbaar is. Smartphones nemen …
