Paper Abstract

Human knee joint movements during walking were analyzed in time and in the three dimensions of space by photogrammetry using highspeed cinecameras and direct linear transformation. Triangular models for the thigh and shank were used instead of the usual stick diagrams. The results are demonstrated in a normal subject and in a typical patient with a movement disorder (spastic diplegia). High accuracy of measurements was achieved. The positioning of the shank and thigh is better demonstrated by such modelling than by stop motion images of the life subject.
