There is conflicting evidence for the effectiveness of rTMS in reducing pain post SCI. Three RCTs found no significant difference between rTMS and sham groups in pain intensity post intervention (Defrin et al. 2017; Kange et al. 2009; Ylimaz et al. 2014). Two RCTs found rTMS significantly reduced pain intensity compared to a sham control treatment (Jette et al. 2013; Nardone et al. 2017). Jette et al. (2013) found that reduction in pain intensity was greater among those incomplete injury compared to complete. Evaluation of potential subgroups that may benefit from rTMS treatment is warranted.
There is level 1a evidence (from four randomized controlled trials; Jette et al. 2013; Defrin et al. 2007; ) that rTMS may not significantly reduce average pain intensity post-SCI.
There is level 1b evidence (from one RCT Kang et al. 2009) that rTMS significantly reduces worst pain compared to sham rTMS.
Transcranial magnetic stimulation may not reduce post-SCI average pain intensity. Transcranial magnetic stimulation may reduce post-SCI worst pain intensity.
