Abstract

A novel procedure for presentation and visualization of gait data has been presented. Values of three main angles (hip, knee and ankle) have been measured in five gait phases on the population of 20 students. After statistical processing for each angle in particular gait phase, ellipsoids containing 80% probability in the distribution has been determined using multivariate normal distribution. Gait normality has been discussed according to the relation of the measured angles and ellipsoid volumes for each phase.
