Abstract :
Due to specialists doctors demand of quantifying some indicators to be used during examination, an original painless solution to estimate in-vivo the human joint passive rigidity is proposed and applied to the elbow joint. It is based on the use of a musculo-skeletal dynamics computation and a linear modelling of the human elbow joint dynamics. Movements acquisition is performed in a motion capture studio during common medical examination for neuro-motor disease. Rigidity of the joint is the linear least square solution of the obtained dynamic system. This method enable the use of indexes such as the condition numbers or the relative standard error that are useful to give interpretation of the results
