The Activator Method uses which characterization of its impulse?

• A. It uses a high-velocity, heavy impulse.
• B. It uses a low-force, precisely directed impulse to specific vertebral levels.
• C. It uses manual thrust without any instrument.
• D. It uses a rotary device to twist the spine.

Answer: (B)

The impulse in the Activator Method is a low-force, precisely directed tap aimed at a specific vertebral level, delivered with a hand-held instrument. This approach emphasizes controlled, localized energy to the target joint rather than a heavy manual thrust. The instrument allows a brief, reproducible impulse that can be aimed at the facet joint or near the vertebral articulation to restore mobility with less tissue disruption.

This differs from a high-velocity, heavy manual thrust, which relies on a stronger, broader force; from manual thrusts without any instrument; or from a rotary twisting device, which composes a different kind of movement altogether.
