Impact of Manipulation of Sacroiliac Joints on the Static Balance of the Body

The procedure of experimental manipulation: the patient lay on the healthy side with the straight lower limb, and the torso turned towards the dysfunctional side, whose lower limb was bent in the hip and knee joint, and the hands rest on the lower ribs on the same side. The therapist allowed the initial loosening of the tissues and chose the movement barrier with his stabilizing hand. Then, with the treatment hand, he introduced the HVLA thrust through the iliac bone towards the bottom, while giving the iliac bone a posterior or anterior rotation - meaning, the opposite to the occurring dysfunction. If during the manipulation, no cavitation sound was heard, the HVLA thrust was repeated once.

The sham procedure was the same, but no external force was introduced in the form of a therapeutic impulse.
