Hello, I had a bad foot surgery 4o+ yrs ago, which left me with a fused foot. The fused foot brought on a gait disturbance and then an SI/pelvic floor rotation. After being in PT for decades, I finally found a PT who specializes in Pelvic Floor dysfunction. She had been specializing for 30+ yrs and told me exactly how my rotation was occurring, then gave me correction exercises. There is a gal , Stephanie Pendergast. in California who specializes. She also has clinics all over the country. Blair Green in Atlanta also specializes. Barbara Green in Charlotte is who I saw. The wrong PT can do damage, and forget about chiropractors! There is a procedure called Prolo therapy where they inject sugar water into the ligaments/tendons to scar the rotating SI into place. It works for some, and not for others. I'm in the process of researching doctors recommended who have helped others with this procedure. Good luck to you! Sandy
