Reproducibility of Plantar Pressure Measurements in Patients with Chronic Arthritis: A Comparison of One-Step, Two-Step, and Three-Step Protocols and an Estimate of the Number of Measurements Required

Abstract

The results of our study indicated that the one-step, two-step, and three-step protocols of collecting plantar pressure measurements in patients with foot complaints secondary to chronic arthritis were all similar. However, the use of the two-step protocol is recommended over the one-step and three-step protocols; the one-step protocol produced a longer stance phase that did not resemble normal walking and when comparing the two-step and three-step protocols, the two-step protocol was less time consuming and less strenuous for patients with painful feet.
