- Charleston brace
- -molded to the child’s body when they are bent toward the convexity of the curve, thus applying more pressure to the curve
- -recommended for curvatures of 25-40 degrees with the apex of the curve below the height of the shoulder blade

PT intervention for scoliosis
- Scroth Method (3 D approach to treatment for scoliosis)
- -improve and maintain flexibility and function
- -improve posture so that the body can regain its original vertical axis.
- -To restore muscular balance, those muscles that have grown longer must be shortened and those that have become shorter must be lengthened.
- -The basis of correction is a properly aligned pelvis; a scoliotic pelvis is often not only shifted laterally but also tilted and rotated.
