Subject Real time, forward musculoskeletal simulation of pathological gait
Abstract My research work is part of the ANR PRCI project OMEGA “Optimization-based forward musculoskeletal simulation of pathological gait”.
The purpose of my research is to study the modeling of musculoskeletal systems involved in locomotion and its effect on pathological gaits.
Simulators have existed for about twenty years, they are mainly used for character animation in video games and movies. More recently, thanks to the sophistication of anatomical models and the improvement of computer performance, these simulators have become more realistic to the point where they are used in medicine, for example, to evaluate forces applied on joints. But their usefulness is limited by their inability to predict motion in response to changes in the musculoskeletal model.
To overcome this limit, it is necessary to design models based on the morphology and gait of the patient. To predict motion after musculoskeletal changes, I will design a controller capable of synthesizing a new gait. The controller will be included in a muscle actuated simulator and I will integrate models of various musculoskeletal disorders. To test and validate our research hypotheses,clinical data will be provided by the Laboratory of Biomechanics and Biomaterials (LBB) of the University Hospital of Hannover (Germany). They will also participate in the model validation.
In the future, this simulator could be used by physicians as a complementary tool to help in the diagnosis, for instance to choose between several treatments. In the context of the OMEGA project we plan to apply the proposed simulator to the design and adjustment of prostheses for leg amputees.
