For C-1 and C-2, the head would be lifted up (tilted back) or tilted forward and the leg length is observed. I've never heard the chiro analyze the difference with an estimated measurement. I've had a hundred or more leg check diagnostics done over the years.

The first time a chiro did leg check on me, he was able to identify every area what I would have problems with. I sought out a chiro who used leg check and the Activator to treat and was under his care for about 15 years. He was fabulous but still had limitations in treating C-1 and C-2 due to the fact C-1 and C-2 do not have faceted mating surfaces like the rest of the vertebra have.

Thus, C-1 and C-2 have limited treatment opportunities compared to the others. The chiro can help to nudge them into position but the patient needs to be disciplined with posture to help that position stabilize over time.
