Joint moments play very important role in biomechanical research related to lower limbs. Three–dimensional motion analysis is widely used in clinical decision making and sport biomechanics. The accuracy of joint moments is particularly important for data analysis. If the joint moments are not accurate, it will mislead the clinical judgment. However there is no method to verify the accuracy of joint moments. To assess the reliability of the joint moments, a new method should be developed. So a new method based on the principle of the transfer between mechanical lower limb work and potential energy was developed. Five healthy student volunteers participated in the study. The motion data were collected and were processed using VICON motion analysis system. The lower limb work and the potential energy were calculated and compared in four kinds of hip joint centre location estimation models. Using the new concept, one of the four models showed the least difference between the potential energy increase and mechanical work. With this concept, the model in which the most accurate joint moment can be calculated was identified. However, given that these techniques are commonly used in the motion analysis laboratory set by researchers and clinicians, more investigations are needed in order to upgrade laboratory setting and joint center prediction methods.
