Sacro-pelvic Parameters and Principles 

Great lecture!

Thanks for this video. The wonderful complexities of the human body never cease to amaze. I've been searching for a simple, single mind body connection thought to achieve proper posture and the one that seems to help is to do with maintaining the sacral slope, so, just thinking "30 degrees" whilst visualising L5 sitting at 30 degrees on the sacrum seems to help maintain a neutral spine and proper posture. How important is it to maintain the sacral angle and has any formal research been done on this concept?

Congratulations, this is great. Greetings from Mexico.

Great

I am recipient of a Nuvasive L3/L4 fusion a year and a half ago and laminectomy discectomy 3 years ago. My problem is fatigue while walking and after having being seated for more than 1h. No surgeon, neuro or orto has conducted such studies before the surgeries. Now in Spain, I have been diagnosed with sagittal imbalance ... and suggestion if a sacroiliac joint fusion to help eliminate the pain... that is still persistent. I am 50YO

I don't understand why not these people just hold their mass center in the center on the frontal plane (not beyond it, not in front of it), if we imagine that frontal plane crosses center of pelvis? if their spine is bowed forward, why not they just lean backward to make their spine straight?

Can

Aaaaaaaaaahhhhh.
