The Pierce Results System is a biomechanical system that analyzes the motion of the spine and the stress views of the spinal column to determine the location of spinal function loss. This system was not developed at one time, but rather evolved over time from other techniques, such as the Toggle Recoil Technique (Upper Cervical), Logan Basic, Thompson, and Reaver Systems. The Pierce Results System utilizes technology such as videofluoroscopy (moving x-ray) that give a computerized thermographic assessment of the spine. It also requires a Pierce 230 adjusting table and computer-assisted adjusting instruments for the best results. With the videofluoroscopy, spinal adjustments are monitored and patterns are detected for optimal improvements.
