Clinical worksheet to estimate gastrocnemius lengths from gait analysis data.

This file contains four Microsoft Excel sheets: (1) “Surgery Calculator”, where users enter knee and ankle flexion kinematics normalized to the gait cycle; a plot of gastrocnemius length over the gait cycle is generated from these input data; (2) “GasMed_Lengths_REF”, which contains a reference table of gastrocnemius lengths computed from the musculoskeletal model used in this study; (3) “GasMed_Lengths_TD”, which contains reference data for the mean and standard deviation of gastrocnemius length over the gait cycle for typical gait; and (4) “Summary Statistics”, which contains summary data describing patient demographics, clinical severity, and surgical treatment.
