Fig. 3: Gait Feature Variability.

Variability of selected gait features calculated on the same measurements performed using Opal and using GaitPy and Mobility Lab correspondingly. The solid line represents the median value; the box limits show the interquartile range (IQR) from the first (Q1) to third (Q3) quartiles; the whiskers extend to the furthest data point within Q1–1.5*IQR (bottom) and Q3 + 1.5*IQR (top).
