The influence of stretch reflexes on the behavior and stability of musculoskeletal systems was examined using a model of human stance. Branches of fold and Hopf bifurcations were computed by numerical bifurcation analysis of the model. The influence of cocontraction and force feedback on the behavior of the posture model was also investigated. It was shown that this study has successfully combined bifurcation analysis with the more common biomechanical concepts and tools to determine the influence of reflexes on the stability and quality of stance.
