The graph shows the reduction in percentage of pain in time. The percentage of pain level modification was calculated from the VAS score by the following equation (post.rTMS - pre.rTMS pain scores) x 100/(pre.rTMS pain scores).

TEST, Phonemic Verbal Fluency, and Visual Analogue Scale (VAS) for pain-0 (no pain) and 10 (maximal pain). The percentage of pain level modification was calculated from the VAS score by the following equation (post.rTMS - pre.rTMS pain scores) x 100/(pre.rTMS pain scores).  Figure 1 below shows the reduction in percentage of pain in time. At the end of the third week of treatment, the pain was reduced about 33.3% (see Figure 1), in fact VAS changed from 6 (pretreatment) to 4 (posttreatment), with CGI-I = 2 (much improved). In three weeks after treatment the percentage reduction of pain was reduced to 25% in the first week after the end of treatment and remained stable at about 16.6% in the second and in the third week after the end of treatment (Figure 1).
