The measured results and other clinical presentations were compared.［Results］The IM4～5 were 13.57°±2.99° and 8.88°±1.88° on average.MIM4～5 were 12.80°±2.86° and 9.28°±2.13°on average. MPA were 18.47°±6.22° and 9.96°±5.39° on average. LDA were 6.55°±4.06°and 3.36°±2.10° on average. WMH were 13.27 mm±1.59 mm and 12.00 mm±1.25mm on average. DPMH were 3.91 mm±1.08 mm and 3.12 mm±0.74 mm on average in patients and normal feet. In the normal persons:IM4～5 were 5.19° to 12.58°, MIM4～5 were 5.09° to13.47° , MPA 1.38° to 19.04° , LDA 1.21° to 7.59° , WMH 9.55 mm to 14.45 mm, and DPMH 1.65 mm to 4.59 mm.There were statistically difference in each measured
