About this trial
Temporal Interference Stimulation (TIS) has been successfully used to help patients with depression. However, its role in alleviating self injuries remained uncertain. This trial will compare the effectiveness of TIS to a placebo control on non-suicidal self injury (NSSI) in patients with major depressive disorder(MDD).
