Advancing the Kinetics Model in OpenSim for Human Motion Estimation Based on IMUs: Performance Analysis with Wheelchair User Motion

Inertial Measurement Units (IMUs) have become increasingly popular human motion estimation due to their portability, self-contained features, and cost-effectiveness compared to marker-based sensing systems which rely on external cameras to observe the position of the markers. Over the years, many studies have proposed various models and...

Three-dimensional ultrasound: Enabling volume measurements with a two-dimensional ultrasound probe

This work investigates low-cost three-dimensional (3D) ultrasound reconstruction from a two-dimensional (2D) hand-held probe with motion tracking. The best available motion tracking is an optical tracking system, which is expensive and requires external tracking hardware. Here, a low-cost manoeuvrable motion tracker, an inertial measurement unit...

Range of motion assessment during total hip arthroplasty: Development and validation of a new instrument for range of motion measurement during total hip arthroplasty

Total Hip Arthroplasty (THA) is a procedure where a defective hip joint with pain symptoms or functional impairment is replaced by a hip prosthesis. During this procedure, the optimal hip prosthesis should be chosen and placed in the correct orientation to achieve a stable hip joint. Failure to do so can lead to dislocation, mechanical failure...

Motion tracking in field sports using GPS and IMU

Injuries are a sportsman’s worst nightmare: They withhold players from playing, they weaken teams and they force clubs to buy a bench-full of substitutes. On top of that, injuries can cause an awful lot of pain. Regulating match and training intensity can drastically decrease the risk of getting injured. Furthermore, it can optimally prepare...
