Pressure distribution measurement vacopedes 2004With the VACOpedes, theload considerably shifts tothe rear foot, the proportionof the rear foot load toforefoot load lies at77% to 23%.Vertical force [N]Integral values:373.8 Nsec111.7 NsecTotal:485.5 NsecWith the Darco, the shiftto the rear foot is smallerthan with the VACOpedes,the proportion of the rearfoot load to forefoot loadlies at 62% to 38%.Vertical force [N]SecondsIntegral values:293.4 Nsec179.8 NsecTotal:473.2 NsecIn a series of experiments,the ankle of the testperson was additionallytaped. The loadproportions were notmeasurably changed bythis. In the example withthe Darco, the proportionof the rear foot load to theforefoot load remains at62% to 38%.Vertical force [N]SecondsSecondsIntegral values:281.2 Nsec171.9 NsecTotal:453.1 NsecThere is practically no changeto the curve progression.With the VACOpedes TC,the proportion of the rearfoot load to forefoot load isexactly the same as withthe VACOpedes:77% to 23%.Vertical force [N]Integral values:366.2 Nsec110.8 NsecTotal:476.9 NsecEven until the very end ofcontact with the ground, theload in the rear foot area isalways higher than that in theforefoot here.SecondsPage 20
