The objective of this study was to develop a new three-dimensional spine kinematic model for abnormal curvature estimation. The morphological diseases such as lordosis and kyphosis are occurred lumbar and thorax segment and the apex of curvature appears the specified segment such as L3 and T6/T7. Therefore, the kinematic analysis of specified segment which is subdivided with respect to the apex of curvature as well as the analysis of whole segment such as lumbar is appropriate to estimate the rehabilitation and diagnosis of back pathological patients. Six healthy male subjects exhibiting no back pathology were participated in this study. Video data was collected with a 6-camera Vicon motion analysis system (Oxford Metrics Limited, Oxford, UK). The developed kinematic model was verified based on the previously published studies. Following the results, the range of peak-to-peak motion in the thorax (approximately 2.6 degrees) was significantly less than the other segment motions and the maximum variation was approximately 6 degrees between the lower lumbar and pelvis. This study expects to be used as a normal man's database to discriminate the diseases of patients and to predict injury in the general industrial workplaces and agricultural conditions.
