title: Assessment of spinal movement reduction by thoraco-lumbar-sacral orthoses.
abstract: Bracing is a common modality in treating spinal fractures. Its objective is to reduce spinal movements and to stabilize the fracture. Until now, factual insight into the movement-reducing properties of Thoraco-Lumbar-Sacral Orthoses (TLSOs) has been missing. Two common TLSOs (e.g., Jewett and Voigt-Bähler) were tested for their movement-reducing properties in two small groups of healthy subjects. In the first study, maximal gross spinal movements, with and without a TLSO, were measured by means of a Portable Posture Registration Set (PPRS) in three different planes. In the second study, maximal segmental vertebral movements in the regions T10 to L4 were measured via X-rays. With few notable exceptions, wearing a TLSO, as measured by the PPRS and X-ray techniques, significantly reduced the segmental as well as gross spinal movements. However, the amount of movement reduction varied greatly from subject-to-subject and was sometimes small. Unfortunately, data are lacking on the amount of movement reduction that is clinically relevant.
