Trodimenzionalni kinematični in kinetostatični model kolenskega in gleženjskega sklepa

V predavanju bomo predstavili postopek matematičnega modeliranja diartrodialnih človeških sklepov s posebnim poudarkom na kolenu in gležnju. Trije glavni koraki postopka vodijo do kinematičnega, kinetostatičnega oziroma dinamičnega model sklepa.   Posvetili se bomo predvsem kinematičnemu modelu, ki podaja gibanje sklepa brez upoštevanja sil, in kinetostatičnemu modelu, ki opiše gibanje sklepa z upoštevanjem zunanjih obremenitev. Kinematični model omogoča podrobnejše razumevanje posameznih anatomskih struktur in je osnova kinetostatičnega in dinamičnega modela. Kinetostatični model nudi po drugi strani pa analizo stabilnosti sklepa ter osvetljuje vlogo pasivnih struktur. Oba modela sta se izkazala kot učinkovito orodje pri načrtovanju protez. 

Predavanje bo v angleščini.

Lepo vabljeni!

3D kinematic and kinetostatic models of the knee and the ankle joints

 

The lecture presents a procedure for the modelling of diarthrodial human joints, with special emphasis on the knee and ankle joints. Three main sequential steps are devised each of them leading to the kinematic, kinetostatic and dynamic models of the joint respectively. In particular, the kinematic model, which can replicate the joint passive motion, i.e. the joint motion under virtually unloaded conditions, and the kinetostatic model, which can replicate the motion of the joint under any external loads, are presented. The kinematic model proves to be of great relevance for a deeper understanding of the role of the joint anatomical structures and is the basic step for the kinetostatic and dynamic models. The kinetostatic model allows the analysis of the joint stability, enlightening the role played by the passive structures of the joint. Both models prove to be powerful tools for the design of articular prostheses.
