Table 2.

Calculation Formula for Evaluating the Function of the Heel Fat Pad.

Amount of change (MIC layer)	=	0% loading (MIC layer)	–	100% loading (MIC layer)
Or
Amount of change (MAC layer)	=	0% loading (MAC layer)	–	100% loading (MAC layer)	(1)
Rate of change (MIC layer)	=	Amount of change (MIC layer)	×	100
		0% loading (MIC layer)
Or
Rate of change (MAC layer)	=	Amount of change (MAC layer)	×	100	(2)
		0% loading (MAC layer)
Deformation proportion × 100 (MIC layer)	=	Amount of change (MIC layer)	×	100
		Amount of change (MIC layer)+Amount of change (MAC layer)
Or
Deformation proportion × 100 (MAC layer)	=	Amount of change (MAC layer)	×	100	(3)
		Amount of change (MIC layer)+Amount of change (MAC layer)

Abbreviations: MAC, macrochamber; MIC, microchamber.
