Pedobarometric Evaluation of the Normal Adult Male Foot

Abstract

Static and dynamic pedobarometric evaluations were performed on the feet of 100 normal adult white men aged from 20 to 49 years old (mean = 29.9 +/- 6.9), using version 3.848 of the F-SCAN system. All evaluations were performed using new pressure sensor insoles with standardized conditions. Maximum vertical forces and plantar peak pressure measurements were taken during 7.88 seconds each of walking in a straight line at subject's own pace and standing. Feet were separated based on their side and lower limb dominance. The means of three consecutive and three alternate tests provided quantitative data. Maximum static and vertical dynamic forces were found to be greater on the dominant side and were significantly correlated with body weight. There were significant differences between dominant and non-dominant sides in static plantar peak pressure evaluations at the forefoot and midfoot, and in the dynamic evaluations at the midfoot. There was a significant correlation between dynamic plantar peak pressures at the midfoot and body weight.

Comparisons of Plantar Pressure Distributions between the Dominant and Non-dominant Sides of Older Women during Walking

“…These findings are consistent with previous studies. Imamura et al 24) found no differences in peak pressure between the two sides when walking. A previous study researched walking speed of older adults and reported that at a slow walking speed there were reduced peak and mean peak plantar pressures the compared to a faster walking speed 23) .…”

Validation of Plantar Pressure Measurements for a Novel in-Shoe Plantar Sensory Replacement Unit

“…Regardless, future studies incorporating kinematic and kinetic data and comparing the location of the CoP to the PSRU sensors would be beneficial. Second, we analyzed a total of five walking trials based on previous studies, 27,28 reporting three trials are sufficient to gain a representative sample of walking gait. Also, the GS-PSD has been designed to clinically measure plantar pressures for research purposes.…”

Walking speed, unilateral leg loading, and step symmetry in young adults

“…Slight asymmetry in one or several variables is considered within normal limits and may reflect functional differences in the contribution of each limb to propulsion and control during walking [2,5,6]. Conversely, gait asymmetry due to a temporary interference or a disorder of one lower limb is considered atypical and frequently indicates pathology.…”
