Searching for the optimal Transcranial Direct Current Stimulation (TDCS) target combined with peripheral electrical stimulation in chronic low back pain: a protocol for a randomized controlled trial

Backgroud: Low back pain (LBP) has been associated with severe impairments, primarily related to activities of daily living, functional ability and quality of life. A multimodal approach to pain management, such as transcranial direct current stimulation (tDCS) and peripheral electrical stimulation (PES), may improve outcomes in chronic LBP. However, the optimal cerebral target for stimulation still remains controversial. This pilot trial aims...
