The determination of the instantaneous axis of rotation of human joints has numerous applications. The screw axis can be determined using optical motion capture systems or electromechanical goniometers. In this paper, we introduce a new method for the localization of the instantaneous screw axis in human anatomical joints from the data given by a spatial mechanical goniometer.

The paper presents the results of comparative studies on the range of active elbow joint motion based on data obtained from 50 physical education students. The measurements were made with both an electrogoniometer and a manual goniometer. An explanation of differences in measurement results has been provided based on an investigation by the photographic method of 3 elbow joints using cadaveric ...

A prototype jig to attach a protein crystallization plate to a standard X-ray goniometer has been designed and constructed in partnership with an engineering firm. This allows a low-cost implementation of in situ diffraction using the available home-laboratory X-ray source.
