About 15 years ago I wanted to demonstrate a an easy way to adjust spondies (that, of course, is the short word for spondylolysthesis), and titled it Spodylolysthesis Simplified. I wasn't expecting the amount of response such a video would bring, and how much I would learn from all of the viewers who were gracious enough to give me their feedback about it.
This short video will share the rationale behind The Spondy School

The videos shown on this channel are not intended to bombard viewers with an excess amount of medical terminology. Yet we recognize that some people enjoy learning as many new medical terms as they can. For your assistance, I am adding the following two Wikipedia links so you can read up on the topics of spondylolysthesis and spondylosis, to help you fill in the gaps of what may be in too short a supply in these videos. Enjoy:
