Our Lyon Brace with removable neck ring (preliminary study)

Background HA-TLS is very difficult to correct using other braces except for the Milwaukee brace (MB). Since the introduction of the MB, a major problem has been poor patient compliance due to the perception of the brace as cosmetically unacceptable. The forces applied to the spine by the MB are well illustrated by White-Panjabi (1). According to circadian biological rhythm, a sleeping person R.E.M. has decreased muscular tone, and gravitational loading force on the horizontal spine is absent. Therefore, common sense tells us to strike scoliosis at night with two combined forces: torsional forces provided by the Lyon brace plus very important elongation forces provided by the neck ring.
