Computerized analysis and modelling of patients with deformities of lower limbs

Pauk J.

Acta of Bioengineering and Biomechanics

2009

Vol. 11, nr 1

47-51

The purpose of this paper was to model the human gait of typical subjects and patients with such deformities of lower limbs as: spastic diplegia cerebral palsy and spina bifida occulta. Model coefficients will lead to the development of a better computer system to support clinical decision-making in human gait in terms of assessment, diagnosis, and classificatio,mnn. Human gait was evaluated by using Motion Analysis System in the Syncrude Center for Motion and Balance in Edmonton. Kinetics data were used for the mathematical modelling based on regression function. The difference between the model coefficients of the patients with the deformities of lower limbs and typical subjects were analysed. There is shown that the model coefficients are different in each group. The modelling can help to define gait pathology and treatment for a large number of patients.

From modelling to assessment of human gait

Pauk J.

Biocybernetics and Biomedical Engineering

2006

Vol. 26, no. 3

85-93

The report is a survey of mathematical model of human gait. The model is based on power developed by muscle joints. Biomechanical modelling requires experimental support in the form of input data and validation of results. As the models become more complex, they are more dependent on advances in experimental methods and transducer development. In this study the regression function and the stochastic approximation function have been used to identify dynamic properties of human gait of normal subjects, patients with spastic diplegia, and subjects with spina bifida.

An Animated Auslan Tuition System

Yeates S., Holden E. J., Owens R.

An Animated Auslan Tuition System uses a computer general signer to provide flexible, visual Australian Sign Language (Auslan) educational tool. Signs are generated and animated by our generig Human Modelling System that is implemented in cross-platform object-oriented C++. The Human Modelling System consists of three modules: the core Human Modelling Module for model construction, manipulation and forward kinetics; the Model Rendering Module for displaying model configuration visually using OpenGL; and the Model Interpolation Module, for providing flexible partial-keyframe interpolation and animation control. These modules form the basis of the Auslan Tuition System, and allow the display of categorised sign phrases, interactive fingerspelling and contextual sign dialogue examples. The user has complete viewing control of sign display and animation, running on modest hardware.
