Recurrence Quantification Analysis of F-Waves and the Evaluation of Neuropathies

Figure 2

Schematic representation of the numeric designation of F-wave recurrence. Note that the numbers increase as the discrepancy between the configurations of the responses increases varying from 100 with marked differences to 0 for similar responses. These values were then used to determine which values were included in the recurrence matrix (the radius). As discussed in the text, lower values would be considered recurrent and higher values nonrecurrent. S1–5 represent individual F-wave recordings.
