摘要: Kinematic characteristics of a body joint performing planar motion are precisely defined by the centers and angles rotation as undergoes its full range physiological movement. These potentially (clinically) useful non-invasive kinematic parameters are, however, highly sensitive to input coordinate measurement errors experimental design. This paper compares results an study statistically based mathematical model in rotation. Guidelines provided design optimal experiments so that, for given equipment, highest possible precision may be achieved results.
