This project takes into account flexion and extension movements, adduction and abduction, as well as rotational movements, allowing for a comprehensive analysis of joint function.
The measurement will take place in six degrees of freedom, analyzing motion not only in the sagittal plane but also in the frontal and transverse planes. Motion parameters and loads will be adapted to the physical capabilities of the knee joint and the requirements of diagnostic doctors.
The use of a motion capture system and an array of ultrasonic sensors will enable precise determination of bone displacements relative to each other—without the need to mount trackers directly on the bones. This ensures that the measurement process is completely non-invasive and does not require interference with tissue structures.
Additionally, a method for presenting results will be developed, along with a database enabling specialists in medical diagnostics to effectively interpret them.
The system will be developed by a team of scientists from the Institute of Machine Tools and Production Engineering at Lodz University of Technology and the Orthopedics and Traumatology Clinic at the Medical University of Lodz. The team includes:
• Katarzyna Piasecka, PhD
• Michał Krygier, PhD
• Sandra Zarychta, PhD
• Grzegorz Kałużyński, MD
