Fig. 3From: Can an insole for obese individuals maintain the arch of the foot against repeated hyper loading?Typical change in BAI over time during cyclic loading. Typical change in BAI over time during cyclic loading in the normal (a), obese (b), and insole (c) groups. BAIs are plotted at the points of maximum and minimum load applied to the foot for 10,000 cycles. The dashed line indicates the diagnostic criterion for low arch (BAI less than 0.21)Back to article page
