Transcranial Electrical Stimulation (TCES) treatment involves applying electrodes to an individual’s scalp to allow electrical current to be applied and presumably stimulate the underlying cerebrum (Tan et al. 2006).
Two RCTs found TCES was effective in reducing average pain intensity compared to sham control (Capel et al. 2003; Tan et al. 2006). Additionally, Capel and colleagues (2003) found significant reducing in use of medications among those in the TCES group compared to control.
There is evidence level 1a evidence (from two RCTs: Capel et al. 2003; Tan et al. 2006) for the benefits of transcranial electrical stimulation in reducing neuropathic and musculoskeletal post-SCI pain.
