Context of the project:
To be able to measure knee joint motion (kinematics) and force (kinetics), an experimental frame coupled with stereo-photogrammetric system (Optitrack) composed of 10 cameras was developed and it is currently used at the BEAMS Experimental Biomechanical Lab (Figure 1). Such system enable to record and measure the kinematics of frames placed on the knee joint during the investigated activities.
Usually, this system is also coupled with a contact pressure measurement device (TekScan reader and sensors) that enables the analysis of knee joint contact pressure, area and force (Figure 2).
The aim of this project is to develop a real-time acquisition system that enable, after the palpation (using an already developed device) of knee landmarks :
- the determination of the knee main joint axis (figure 3) and knee joint kinematics in terms of rotations and translations [1,2];
- to synchronize the TekScan measurement with the knee kinematics;
- the storage of the data in a standard format to enable fast analysis.
