[Biomechanical analysis of locomotion patterns of the lower extremity. I. Acceleration].

Starting with his own biostatic analysis of strains and stresses affecting the human hip joint the author here extends his observations to include movement. Since the acceleration rates of individual parts of the body have to be known to calculate internal joint forces, calculations done a realistic three-limbed model are described. The braking process following a free fall from a height of 1.5 m is analyzed as a simple locomotion pattern and the calculated acceleration rates are compared with measurements published in the literature. With the model presented here locomotion patterns can be described very well and quantitatively recorded.
