Experimental Evaluation of Balance Prediction Models for Sit-to-Stand Movement in the Sagittal Plane

Figure 3

An example of balance control prediction for normal sit-to-stand conditions (a) and demanding sit-to-stand conditions (b) (subject C). The solid lines show the boundaries for sit-to-stand balance control calculated with the inertia variable model, while the broken lines show the boundaries calculated with a simple inverted pendulum model. The open circles represent the successful sit-to-stand data while the closed circles represent the unsuccessful sit-to-stand data. In order to consider a data to be stable, the whole error bar on the point should be inside the boundaries.
