Popis:	Introduction Manipulation of the equine ilium and sacrum is utilised to assess range of motion at the SIJ. Motion of the ilium and sacrum during manual force application to the equine pelvis has been measured previously in vitro. The aim of this study was to measure the amount and direction of motion in vivo including comparison of bone fixated and skin mounted sensors. Methods Orientation sensors were skin-mounted over tuber sacrale (TS) and 3rd sacral spinous process (SP) of six standing Thoroughbred horses. Orientations of each TS and sacrum were recorded by one investigator during six trials of manual force applied to the pelvis, inducing cranial, caudal and oblique rotations. The study was repeated with the sensors mounted onto pins implanted into TS and SP. Mean values were reported in Euler angles for the three orthogonal planes lateral bend (LB), flexion-extension (F-E) and axial rotation (AR). Correlation between skin and bone fixated markers (Spearman R) was determined with significance set at P
