| Outline of Final Research Achievements |
This study inevestigated contact force at medial compartment of tibio-femoral joint (medial knee contact force) during gait based on musculo-skeletal model. The muscle activation patterns recorded by surface electromyography (EMG) were compared to those analyzed by the simulation. The result showed that the muscle activation in the model-based simulation analysis had similar patterns to the EMG activation. It is confirmed that the simulation model had validity to analyze gait motion. Next, using the validated model, we investigated the relationship between the medial knee contact force and the physical function in elderly. An increased medial knee contact force was correlated to the physical dysfucntion. Next, the effect of toe-out gait on the medial knee contact force was investigated. The reuslt revealed that medial knee contact force had a significant decrease in the toe-out gait compared to the normal gait. Toe-out gait may be useful to reduce the risk of dysfunction in elderly.
