Biomechanical volunteer study.To quantify the stabilizing effect of 2 different semirigid thoracolumbar orthoses during various body movements.Various spinal diseases need to be treated by immobilization. The literature shows, that immobilizing strongly depends on orthosis design and loading direction. Few data are available for directions other than flexion extension.Ten young healthy volunteers (22-44 yr, 5 male, female) performed 4 tasks: full active flexion/extension, lateral bending, axial rotation as well a everyday movement (flexion plus bending rotation). These tasks were carried out without orthosis, with DorsoFX (BORT GmbH, Weinstadt-Benzach, Germany) SofTec Dorso (Bauerfeind AG, Zeulenroda-Triebes, Germany). flexibility spine was measured using 3-dimensional motion capturing system (Zebris Medical Isny, Additionally, pressure exerted subject's surface sensor (Tekscan Inc., South Boston, MA).The range significantly decreased in all planes 42% 69%. largest decrease smallest decreases observed extension (DorsoFX), (SofTec Dorso), respectively. differences between small not statistically significant. similar both but differed movements.Both had spine. movements, which indicates should tested understand an completely.
