Comparison of external force under the fifth MTH due to differences in shoe width (□ fit width vs. ■ narrow width). (a) Peak normal stress (pressure) (PP) and peak shear stress (PSS), (b) normal stress (pressure) time integral (PI) and shear stress time integral (SSI), and (c) shear stress/normal stress (pressure) ratio of peak value (SPR-p) and shear stress/normal stress (pressure) ratio of time integral value (SPR-i). * p < 0.05 paired t-test. Error bar was standard error (SEM). MTH: metatarsal head.
