Project Summary
For the Human Joint Kinematics Project we used 3D data files of the human skeleton obtained via IVLs laser scanning system to create both still and animated representations of human joint motion. We developed these images for the purpose of enhancing the instruction of students in both the Physical Therapy and Occupational Therapy programs at Idaho State University.
We are particularly interested in depicting the changing relationships between the moving surfaces of the two (or more) bones that serve as the joint partners, during both normal and abnormal motion and during therapeutic interventions. We plan, over the long term, to develop animated illustrations of joint motions at all of the major joints of the body, but so far have focused on the elbow.
Each of the data files representing the human humerus, radius and ulna were imported into a 3D modeling and animation program where we added shading to the bone surfaces to make them look more realistic. We then positioned the 3D bone images relative to one another so that they were oriented as they would be during normal living function. We then created animations to depict camera movement, joint movement or both. We also added other graphic elements, such as text, arrows, etc. that enable us to explain the instructional concept we are trying to illustrate.
In the future, we will be modeling other anatomic structures to provide a more complete representation of motion as it occurs during both normal function and dysfunction. In the future application, we plan to position bones “inside” a semi-transparent human figure for use during surface anatomy and palpation instruction so that students are able to visualize anatomical structures through the skin.
