The figure shows on the left how the sensors were worn by the test subjects. In the centre there is an image of the subject performing an asymmetric stoop and the rectangle defining the lifting activities area. This also shows the position of the stations according to the rules in Section "Experimental protocol". The right side of the picture shows the worker while carrying a load (flat surface), sitting, or carrying a load on an inclined surface.
