Figure 3. Recorded centroid traces of respective anatomical sections across all three axes during the execution of an example task of the SHAP test, the key task, for able bodied group, Patient 1 with classical prosthesis and Patient 1 with advanced prosthesis.

The origin of the coordinate system for the each anatomical section was set at the starting (resting) point of the respective section with z axis pointing vertically upwards, parallel to the patient’s vertical axis and x, y axes aligning with the transverse and the sagittal one.
