[Experimental determination of muscle coordination of the lower extremity].
In order to describe the lines of action of muscles acting on joints, data on the geometrical position of insertions and origins are needed. These are of fundamental relevance for the biomechanical analysis, in particular for the calculation of joint loading. A measuring device with an accuracy of 0.1 mm was designed and constructed for the collection of three-dimensional experimental data from wet anatomical specimens. The main design features of the device include a vertically adjustable stand on wheels and a rotatable scale ring with a radial pointer. After setting the reading, the apparatus permits the measurement of cylindrical coordinates The margins of the attachments of muscles acting on the hip and knee joints were measured in two specimens. Two extensive sets of morphological data are now available and can be used to create complex biomechanical computer models.
