The brace has a rigid dorsal panel attached to the central back portion of the band and extending upward from a lower end aligned with the lower edge of band, upward to an upper end. The upper end and the lower end are spaced by a distance corresponding to a distance between a sacrococcygeal junction and a position below the patients third thoracic vertebra.
