Figure 6.

Bar-graph depicting averaged NPRS ratings of participants by group. Significant differences in subjective pain levels relative to baseline were observed for all three groups 5 min post-application (p < 0.001), 20 min post-application (p < 0.001), post-motor learning acquisition (35 min mark) (p < 0.001) and post-motor learning acquisition (45 min mark) (p < 0.001) as indicated by an asterisk. At 20 min post application there was a significant difference between the local and contralateral groups (p = 0.02) as indicated by a double asterisk. Error bars represent the standard deviation.
