Summary

This study tests whether a gentle electrical stimulation device (acu-TENS) can reduce pain during a procedure called manual vacuum aspiration, used to treat early pregnancy loss. About 108 women will be randomly assigned to receive real acu-TENS or a sham device. The goal is to see if acu-TENS provides meaningful pain relief and is safe.
