During the infancy period of development, Mr. Hooper and Dr. Charles T. Price conducted a comparative analysis of the brace in standing and supine positions. The findings demonstrated the hypothesis that in-brace x-rays taken in a standing position are of no value when assessing the efficacy of a night-time orthosis when treating scoliosis.

The design of the brace is meant to shift the spine into an asymmetrical position. When the patient stands, he/she will unconsciously try to force the spine into an elongated or upright position in order to balance themselves. The biomechanical forces applied by the brace are then negated when a patient is forced into a standing position. This compromises the principles on which the bending brace was designed and prevents any viable evaluation of the brace.

In order to evaluate brace efficacy -All in-brace radiographs must be taken while patient is supine
