Investigation of Impact of Walking Speed on Forces Acting on a Foot-Ground Unit.

Static and dynamic methods can be used to assess the way a foot is loaded. The research question is how the pressure on the feet would vary depending on walking/running speed. This study involved 20 healthy volunteers.

Cellular Polyolefin Composites as Piezoelectric Materials: Properties and Applications.

Piezoelectric polymers characterized by flexibility are sought for applications in microelectronics, medicine, telecommunications, and everyday devices. The objective of this work was to obtain piezoelectric polymeric composites with a cellular structure and to evaluate their usefulness in practice. Composites based on polyolefins (isotactic-polypropylene and polyethylene) with the addition of aluminosilicate fillers were manufactured by extrusion, and then polarized in a constant electric field at 100 V/µm.

Quantitative Analysis of Foot Plantar Pressure During Walking.

BACKGROUND There are many methods of dynamic analysis of foot loading, however, we still need a simple, easily applicable system for foot plantar pressure analysis. In this study we asked the question: "Can a new system for foot evaluation, the ITE System, provide a good quantitative dynamic foot pressure analysis? Can it be used in clinical practice?". MATERIAL AND METHODS Twenty healthy volunteers, 8 females and 12 males, aged 20 to 25 years old took part in this study.
