The head, trunk, and pelvis movements were examined simultaneously to analyze the direction and the timing of the movement of each body segment. Subjects were 21 healthy young subjects (11 male, 10 female). A three dimensional motion analyzer (Vicon370) was used to measure exact angle displacement of all direction of the head, trunk and pelvis movements. A tilting platform tilted to 20 degrees with the tilting velocity of 5 and 10 degrees per seconds to induce the tilting reaction. The movements of flexion-extension, lateral flexion, and rotation of the head and trunk, also anterior-posterior tilt, lateral tilt and rotation of the pelvis were measured. The order and tilting angle of the platform at beginning of induced movements, also the directions and angle of the movements of each body segments at maximum tilt (20 degrees) were analyzed. All the movements were induced before tilting angle was reached 10 degrees. The movements that happened in the early stage of the reaction were trunk rotation and lateral flexion to opposite side (TRO and TLFO), head lateral flexion to opposite side (HLFO). The pelvis movements began in the late stage of the reaction. These findings regarding timing of the induced movements were clear in tilting velocity at 10°/s. The main directions of the movement at maximum tilt were HLFO, trunk flexion (TF), TLFO, TRO and opposite side lateral tilt of the pelvis（PLTO). Also the ratio of ROM (induced / active maximum ROM) of HLFO, TF, TLFO and TRO were 16%, 10%, 36% and 16% respectively and other movements were less than 10%. 　These results demonstrated important direction and timing of the movement of each body segments during tilting reaction in sitting position. It is suggested that physical therapist should induce HLFO, TF, TLFO, TRO and PLTO, especially TLFO and TRO in the early stage of the reaction.
