Mean and standard error of mean (SEM). (A) Change on numerical pain scale [NPS (0–10)] during conditioned pain modulation (CPM)-task; (B) Short intra-cortical inhibition (SICI) expresses the relationship between the amplitude of wave and motor evoked potentials (MEPs) (relative amplitude, express in %), at inter-stimuli intervals (ISIs) of 2 ms with paired-pulse. The first is a sub-threshold stimulus [80% of the rest motor threshold (rMT)] followed by the second one which is a suprathreshold stimulus (130% rMT). Spectrum of structural pathology to absence of tissue injury to persistent nociceptive input. The error bars indicate the SEM. An asterisk indicates a significant difference between groups according to spectrum of structural pathology to absence of tissue injury to persistent nociceptive (P < 0.05). A MANCOVA was used to perform the comparisons, followed by the Bonferroni correction for post hoc multiple comparisons.
