I live in PA, Bucks County. I am an LPN. Was doing pediatric home care. I fell a year and a half ago on a wet wheelchair ramp, carrying the child I was caring for. I have severe back pain and spasms. I was dx with spondylolysis, and herniated discs at L4-5, L5-S1. I also have spinal stenosis thru the thoracic vertebrae (all the lifting thru the years). I tried rest, 3 epidural injections, PT, nothing helped. On referral from a friend, I went to a chiro. I had seen one many years earlier, he was crack you back, and run kind of chiro. I think he hurt me more than helped. So I was skeptical. My new chiro, who I have seen 3 to 4 times a week almost steady for a year does flexion distraction and torque release. The flexion distraction is a technique of traction to allow the inside of the disc to move back into it. The torque release is how he does the adjustment, with a tool that only adjusts the vertebrae that need to be adjusted. It is a gentler, but very effective technique. Especially for me, as I am very tender. I would, and have referred people to him. Or anyone else that does this form of adjustment. I finally won (with the WC judge) for this treatment to be paid for. But I have finally decided to have spinal fusion done, as the L5 vertebrae has slipped forward some, and is now dx as spondylolisthesis. Good luck with your survey.
