This is a spinal adjusting procedure that uses a spring-loaded, hand held instrument to provide a quick, low-force impulse to the designated area. It is used for the entire spine and the extremities. Very good for young children, older adults with certain spinal conditions. But it can be used by anyone who wishes not have have a hands-on adjustment. This technique was researched extensively and developed by Arlan Furh, DC - a graduate of Logan College of Chiropractic in St. Louis.
