| Outline of Research at the Start |
We propose a new bioinspired multiscale forward finite element musculoskeletal model to deterministically investigate the individualized biofeedback of relevant mechanical signals to guide the design of rehabilitation and artificial prosthesis design.
|
| Outline of Final Research Achievements |
The whole body multi-scale finite element musculoskeletal (FE-MS) model of humans has been developed with the function of subject-specific.(1) An algorithm for the prediction of ground reaction force was developed and integrated with the FE-MS model. A super accuracy has been found in comparison with conventional approaches.(2) It has been applied to the clinical field and used to understand the effect of lower limb alignment on multi-scale dynamics from knee and body levels.(3) A wearable motion capture system has been developed for synchronously acquiring the kinematics and EMG of humans.

| Academic Significance and Societal Importance of the Research Achievements |
This research provides a deterministic way to insight into the relationship between physical behavior and tissue state, which significantly provided a fundamental understanding of human biomechanics and help treat musculoskeletal disease.
