The predecessor to the Blair procedure, the Toggle Recoil approach is very similar to the Blair technique. It differs mainly in the type of x-ray analysis to determine spinal misalignment, however the overall process is very similar to that of the Blair adjustment.
Knee Chest doctors used the same thermographic technology used by Blair doctors to check for nervous system imbalance, which can indicate if an adjustment is needed. They differ from Blair doctors in the x-rays that are used to assess spinal misalignment as well as the technique used for the adjustment. This procedure does involve some turning of the head, and often an audible “pop” is heard in the adjustment, yet when done accurately is still an extremely same and effective procedure.
The following three upper cervical techniques differ from the previous three in the types of x-rays utilized and in the assessments they use to determine if a spinal subluxation is present, if an adjustment is needed, and if it has been corrected effectively. They generally do not use thermographic analysis as much to assess for spinal misalignment/subluxation, but rather utilize an additional emphasis on postural assessments and muscle tone to determine the progress of a patient and if they have a misalignment in the upper neck. The main difference within the following technique systems is in the adjusting procedure.
