Difference in Foot Pressure between Partial Weight Bearing and Discernment of Weight

The purpose of this study was to verify in which part of the sole of the foot sensory perception takes place in learning partial weight bearing (PWB) and discernment of weight (DOW). The subjects were healthy adults, 11 mmales, 10 females. Using the F-scan, we measured the center of foot pressure and the peak of foot contact pressure in learning PWB and DOW. Two conditions (1/2 and 1/3 of weight) were measured in PWB, and four conditions (weight on the front or back of the foot in the seated and standing positions) were measured in DOW. We could not find a difference in the extent of sensory perception, but there was a wide dispersion sensory perception in the standing DOW task. We consider that improvement in PWB skill is achived by applying foot pressure through the big toe and metatarsal which support the flexibility of the leg joints.
