This category contains both high velocity – low force adjustments accompanied by “popping or cracking” sounds, and slower sustained force adjustments.
This category is largely hands-on, as in the first category, but with assistance from movement of the adjusting table.
This category covers a wide variety of instruments ranging from hand-held manually powered to computer assisted. All involve direct chiropractor diagnostic input and implementation. This group includes one of my favorite and most versatile techniques, the PulStar, which has the dual ability to analyze spinal function and deliver a precise, gentle tonal adjustment.
