The assessment of dynamic foot-to-ground contact forces and plantar pressure distribution: a review of the evolution of current techniques and clinical applications.

The objective documentation of foot function before and after therapeutic intervention will be greatly enhanced by the utilization of devices capable of measuring dynamic foot pressure distribution. Efforts to develop this technology date back to the late 19th century, but only with recent advances in computers has it been possible to produce quantitatively accurate high resolution foot pressure distribution with high sampling rates and easily interpreted graphic displays. Over the years, a variety of methods have been employed to study foot pressure. Many of these techniques have already improved our understanding of the foot and its function, and have had an impact on the way we practice. Effective clinical utilization of these new investigative tools depends on an understanding of their scientific basis, capabilities and limitations.
