Assessment of Waveform Similarity in Clinical Gait Data: The Linear Fit Method
Figure 1
Two exemplificative knee sagittal kinematic datasets were compared in order to graphically illustrate the LFM. The circles represent the 100 values obtained for the two knee kinematics when time-normalized and reported in terms of gait cycle. On the left are the points for the investigated dataset (black dots) and for the reference dataset (grey dots). The grey line represents the reconstructed curve obtained by the parameters of the linear fit applied to the values of when plotted versus (right plot).
