Abstract		Detailed model of the elevation of the human arm is developed. The model is based on the measurements with one CCD camera connected to a PC computer that processes the images. Several mathematical analyses were applied to define the changes of the lengths of the clavicular link and of the upper arm link during the elevation. It was observed that the length of the clavicular link is first decreasing and then it is increasing with a relatively constant gradient. On the contrary, the lenght of the upper arm link is first increasing and then decreasing. The gradient changes at about 100 degree of the arm elevation. A significani parameter in the model is the initial offset of the clavicular rotation.
