What is High Velocity Low Amplitude?

High Velocity Low Amplitude (HVLA) is a specific type of manual adjustment commonly used in chiropractic and manual therapy. It involves a quick, precise movement applied over a very short range of motion to a joint that is restricted or not moving properly.

“High velocity” refers to the speed of the movement, while “low amplitude” means the adjustment is small and controlled. The goal is to restore normal joint motion, reduce irritation to surrounding nerves, and improve overall function.

You may hear a clicking or popping sound during the adjustment, which is simply gas releasing from the joint—not bones moving out of place.

When appropriately applied, HVLA can help reduce pain, improve mobility, and support better nervous system function as part of a comprehensive treatment approach.
