Electroacupuncture devices use small electrical currents to stimulate acupuncture points.
ATOIMS (Automated Twitch-Obtaining Intramuscular Stimulation) and ETOIMS (Electrical Twitch-Obtaining Intramuscular Stimulation) are forms of electrical acupuncture that stimulate nerve and muscle tissue to twitch, thereby helping to “jump start” and “wake up” the nerve and muscle so that neuromuscular function can be restored.
A 2011 study found "some evidence for electroacupuncture as an alternative technique to provide postoperative analgesia in dogs."
