Can a faint zap beat pain? new study puts nerve stimulation to the test

This study looked at whether very low-level electrical stimulation of nerves near the spine can reduce chronic pain more than a sham (inactive) device. Twenty adults who already have a nerve stimulator implant took part. Each person received both the real low-level stimulation and the sham for 5 days each, without knowing which was which. The goal was to see if the stimulation truly helps with pain, sleep, and mood.
