Spinal Wave Retention Times
Lie prone, forehead on stacked hands. Identify which spinal levels are "fast" (low retention) and which are "slow" — the slow ones are not stiff, they are highly absorbent.
Full Lesson Notes
Complete Practice
Lie prone, forehead on stacked hands. Send a slow longitudinal wave down the spine by rolling the pelvis very gently anterior-to-posterior, allowing the wave to propagate cephalad through the ribs and skull. Borrow chromatographic elution as the operational frame: each vertebral segment is a stationary phase with different affinity for the wave, so different segments will register the pulse at different retention times. Identify which spinal levels are "fast" (low retention) and which are "slow" — the slow ones are not stiff, they are highly absorbent.
