A Gentle Correction a gentle touch and controlled contact on the first vertebra in the neck is designed to restore balance to the spine and nervous system. Even though the adjustment is administered at the neck, the efforts of the correction influences the whole spine and ALL body systems. This is because the NUCCA chiropractic and QSM3 procedures influence one of the highest control centers of body balance and healing, the brain stem and central nervous system. Patients find the adjustment to be very comfortable. There is NO CRACKING, NO POPPING AND NO TWISTING OF THE SPINE.
