Complete Practice
Lie on your side with the lower arm extended above your head and the upper hip stacked, then introduce a slow yaw rotation of the entire torso around its long axis — once every ten seconds, ten degrees in each direction. While turning, add a tiny secondary tremor in the top hand, a one-hertz lateral shake, and watch how the amplitude of that shake changes as the trunk passes through different orientations. Map which torso angle most distorts the hand's small motion, because that angle marks where gravity is doing the most asymmetric work on your shoulder girdle. Challenge: Ten-degree torso yaw in side-lying is gross compared to the small tremor it modulates; coupling at the shoulder may swamp the orientation-dependent signal.
