Spinal Adjustment

Spinal Adjustment (High-Velocity Low-Amplitude Thrust)

The most frequently used chiropractic technique, spinal manipulation, is the traditional high-velocity low-amplitude (HVLA) thrust. The adjustment often results in an audible "pop," as chiropractors use their hands to apply a controlled force to a joint while the body is positioned in a specific way. The audible popping or cracking sound that you hear during the (facet)joint adjustment is the volume within the joint increasing suddenly as the joint is gapped. This distention snaps the joint capsule and acts like a drum causing a popping sound.

Spinal Mobilization (Low-Force or Gentle Chiropractic Techniques)

Some conditions (such as osteoporosis), pathology, the patient's size, patient comfort, or patient preference, may require a gentler approach generally referred to as spinal mobilization. In addition, some patients and/or clinicians prefer mild spinal mobilization techniques that do not involve twisting of the body or a forceful thrust.
