Right short leg, or left brain dominant?

April 21, 2014

When I was in Chiropractic School we were taught that a right short leg indicated a posterior pelvic ilium, or PI as we called it. This short leg lead to a host of aberrant kinetic chain difficulties including a pelvic unleveling and subluxations of L4/5 vertebrae leading to lower back pain and disc disorders if left untreated. Sounds logical, and there is merit to this kinetic chain biomechanical model.   However, as I started checking people, it seemed to me there are an aweful lot of people with right short legs, and not everyone has back pain? Some of them had shoulder and neck pain.

Well, they would tell me, the kinetic chain if untreated, will subuxate all the way up the spine to the neck. Wow! I thought. Seems a simplified explanation but ok. I accepted the teaching. As I began to speak to people I realized that biomechanics are not the only thing affecting pain syndromes. What if the problem was not coming from the pelvis, or the short leg, but instead was an indication of what was going on in the brain?

It seems that stress, daily emotional and mental demands and the act of living in a left brain dominant society leave the right brain lacking stimulation. Maybe the right brain is understimulated, or afferentated as we say in chiro neuro circles. It would cause an increase of tone in posterior musculature on the ipsilateral side, in this case, causing a right short leg.

The biomechanics are important but the body is more complex than simple biomechanics. The brain is the driver of tone and balance. Remember the right hemisphere is the side that loves to be out in nature, whether the mountains or the beach. Wherever it is that you feel connected and filled. It loves to move slow and linger in space. It loves creativity, music, and does not have a time agenda or schedule.
