Rotational motion refers to the movement of an object around a fixed point or axis. It occurs when an object spins, rotates, or turns in a circular or curved path rather than in a straight line. Full definition
These include a printable and flexible gyroscope that measures rotational motion of the head and body balance and a printable and flexible 3 - D accelerometer that measures lateral head motion and body balance. (sciencedaily.com)
Although such measurements have been performed in much larger scale systems, the latest results were achieved within a micrometer - sized waveguide — a thin wire that guides light — and demonstrated the use of optical torque to induce rotational motion in a microscale mechanical device.

Added challenge of contraction to the glute (buttock) structure and rotational motion for the thoracic spine encompasses primal movement. (onnit.com)
