Example of different Base of Support definitions

Using heel strike as an example, this diagram shows how different definitions of BoSML would incur different measurements of MoSML for the same position of XcoMML (star). Heel strike has just occurred for the right limb so MoSML is measured for the right limb. The diagram shows BoSML measurements taken from the Centre of Pressure [CoP] (black circle), at the midpoint between the 2nd metatarsal and calcaneal marker (red circle), at the lateral malleolar marker (blue circle) and at the midpoint between the 5th metatarsal and lateral malleolar marker (green circle). The MoSML measurement for each method is shown with a dotted line. This figure was created by FW
