Abstract Background Development of reliable and objective evaluation methods is required particularly for natural and goal-oriented upper-extremity tasks. Three-dimensional imaging measurement techniques have turned out to be a powerful tool for a quantitative and qualitative assessment of multijoint movements. The purpose of this study was to develop and test a method of threedimensional motion analysis for the activity drinking from a glass and describe the drinking task with kinematic variables in control subjects. Methods A protocol was developed for the drinking activity including the set-up of cameras and positions of the markers and the subject. The drinking task included reaching forward transport with glass drinking back transport and returning the hand to the initial position. An optoelectronic system was used for the .
