A Spring loaded adjustment tool, used to deliver gentle manipulations to spinal joints, muscles and extremities              

Pressure that is applied to the bone which in turn "unlocks" it from its improper position. The bone will then be free to align itself correctly.

Cushioned wedges, which are placed under each side of the pelvis along with gentle maneuvers
