The spine functions as a powerful engine and initiator of movement, driving functional movement through a wave of contraction from core to periphery.

“the the book that everyone loves to re reference is called um the spinal engine by gravitki and it's a really like it's a hard book to read everyone it's like gnarly biomechanics of salamanders side bending and um but really hints at that this is a really great whip that the the spine is a powerful engine and initiator of movement and that's actually how we define functional movement in the first place works of a wave of contraction from trunk to periphery from core to sleeve from axle skeleton. It's a peripheral skeleton.”
