Figure 2

Heat maps for the average measurement errors of the sacral slope were drawn for positional variation in flexion, obliquity, and rotation. Blue indicates the errors in sacral slope ranging between − 7.5° and − 2.5°, scarlet indicates those between − 2.5° and 2.5°, and yellow indicates those between 2.5° and 7.5°. The average measurement errors of sacral slope are shown when the pelvis is positioned as follows: [Microsoft 365 Excel (Microsoft Corporation, Redmond, Washington, USA) was used to create the image. (a) In − 45° flexion. (b) In + 45° flexion. (c) In − 10° obliquity. (d) In + 10° obliquity. (e) In − 20° rotation. (f) In + 20° rotation.
