Prone Pressure-Contour Gradient
Lie prone and mentally draw level curves of pressure on the floor — isolines connecting points of equal contact force. Locate the steepest pressure gradient under your body and track how it migrates as you make minute postural changes.
Full Lesson Notes
Complete Practice
Lie prone and mentally draw level curves of pressure on the floor — isolines connecting points of equal contact force. Now shift weight slightly toward one shoulder. The contour spacing tightens somewhere and slackens elsewhere; tight spacing means a steep gradient. Locate the steepest pressure gradient under your body and track how it migrates as you make minute postural changes.
