Thompson technique, also known as drop table, is a full-spine adjusting technique that, like the diversified technique, utilizes high-velocity, low-amplitude (HVLA) along with low-force adjustments using a drop table. The special precision adjusting table known as a drop table has several segments called drop pieces that can be moved so that when the thrust is delivered the table will slightly drop allowing gravity to assist and work in combination with the manual adjustment. Determined by specific X-ray analysis.
The drop segments help by:
Assists in the thrust. Minimizes the force/energy required for the adjustments
Opens the joint during the adjustment
Although the table segments drop comes to a rest, the patient’s body momentum continues which is also helpful to the Thompson technique because it aids in alignment.
