Abstract EN
The assessment of waveform similarity is a crucial issue in gait analysis for the comparison of kinematic or kinetic patterns with reference data.
A typical scenario is in fact the comparison of a patient’s gait pattern with a relevant physiological pattern.
This study aims to propose and validate a simple method for the assessment of waveform similarity in terms of shape, amplitude, and offset.
The method relies on the interpretation of these three parameters, obtained through a linear fit applied to the two data sets under comparison plotted one against the other after time normalization.
The validity of this linear fit method was tested in terms of appropriateness (comparing real gait data of 34 patients with cerebrovascular accident with those of 15 healthy subjects), reliability, sensitivity, and specificity (applying a cluster analysis on the real data).
Results showed for this method good appropriateness, 94.1% of sensitivity, 93.3% of specificity, and good reliability.
The LFM resulted in a simple method suitable for analysing the waveform similarity in clinical gait analysis.
