The Spinal Engine

The book presents arguments and data that suggest the spine, rather than the legs, is the main engine for human locomotion.

It traces this function back to our fish ancestors and explains how the spine's activity has evolved to guide the pelvis during gait.

The book provides a theoretical and clinical analysis of the normal function of the spine, describes how its function degrades, and proposes a method for objectively measuring spinal function.

It also discusses the clinical use of this methodology and its implications for understanding and treating spinal injuries.
