Sorry for your unsuccessful search. I have had 4-7's ligaments tightened by a Dr. who learned the techniques at Schultz and it was successful. Number 4 was the worst as described by a Digital Motion Xray. The work stopped the worst symptoms but I still have some, so I just do a 'palace guard" neck movement .... chin to the chest and stretch the neck up. I seems to realign the joints. Have had the SI Joint worked on as well and again the same kind of results ... no more partial dislocations or wild hip swings but again I have a movement to realign the joint when it goes off a bit. Good luck.
