The ground reaction forces have been processed by means of wavelet transform. Results of the wavelet analysis are represented in a time-frequency plane, by tiles. These are coloured in different grey levels associated to the values of a suitable energy function of the expansion coefficients, resulting from the wavelet transform. The high frequency tiles revealed the presence of irregularities with clinical significance in the firts part of the stance phase. These transients in ground reaction forces are described in a quantitative manne allowing to monitor their evolution during the patient observation time. The heel strike transient has been identified by the tile representation of the vertical component of ground reaction forces and confirmed by its correlation with corresponding irregularities in the other components.
