To confirm whether you have a twisted sacrum, do this self-appraisal.
You also do self-appraisal before every practice session of Comfort Your S-I Joints — necessary to know for which side to do the exercises — and sacral position has been observed to change from session to session, so do it every time.
To get the complete regimen, send blank email to s-i.joint.pain@somatics.com. Read the full write-up on the condition at http://lawrencegoldsomatics.blogspot.com/2011/04/understanding-sacro-iliac-joints.html
