Prevention and improvement of existing therapies
Inverse dynamic models were used to conclude from observed motions to forces and moments acting in the spine and at surrounding structures. These loads allow evaluation of the stress conditions in joints, joint cartilage, bone, muscles, tendons, and ligaments. Analyses can be performed for any static and dynamic load scenario during physical training or in daily routine.
The researches of our team aim to conclude from normal as well as from highly demanding daily activities to the loads in the spine. They intend to evolve methods for prevention and improvement of existing therapies.
For optical motion capturing we use the "Vicon" system. Small reflective marker balls were fixed on certain landmarks on the skin of the subjects. During the subject's motion in the laboratory cameras detect the marker positions.
Subsequently, the recorded motions were input into the invers dynamic models for analysing the resultant forces in all muscles and joints.
