Comparison of the reliability of plantar pressure measurements using the two-step and midgait methods of data collection.

The reliability of plantar pressure measurements obtained using the traditional midgait method compared with the two-step method was investigated. Using an EMED-SF system, the parameters of contact area, contact time, maximum force, and peak pressure at seven sites of the foot were assessed for reliability of measurement in 10 normal subjects. The results of the study indicate that the two-step method is as reliable as the midgait method and may be preferred for use in both research and clinical settings.
