Well, I really will need lots of updates on this! Just so glad that Joseph E. Muscolino, DC is a practitioner that chose to write about his belief that the thoracic part of the human body can, and does, affect every other part. It can affect the cervical spine by affecting the body of the first thoracic vertebrae, which affects the last cervical one (that starts the cervical vertebrae on a hypolordotic curve, which ends up causing the upper cervical vertebrae into a hyperlordotic curve). Since the discs are in an anterior position, this affects the discs at the top of the thoracic area and the bottom of the cervical area because the weight of the head is anterior. Since the hyperlordotic curve causes excess weight on the posterior portion of the vertebrae, the upper cervical ones tend to cause bone/arthritis changes and nerve compression. Another consequence of the weight of the head being anterior is that that weight causes muscles and other soft tissues (ligaments and tendons) in the posterior region of the neck to work very hard (and become even “tighter” (see previous post!)). The last thing that I read about in this section is the effect the thoracic spine can have on shoulder posture. Naturally, the shoulder girdles fall into a forward posture as well, which, in turn, turns the humerus and all other soft tissue in, towards the center of the body, with them (think previous “tighter/locked” muscle discussion again!).
