Acustimulation involves electrostimulation of acupressure points (most commonly, the P6 point) by transcutaneous, electrical stimulation through a wristband device. A wristband device currently available is the Reliefband®, a class-II device approved by the U.S. Food and Drug Administration for the treatment of chemotherapy induced nausea and vomiting (CINV). The device delivers slow, weak, electrical impulses to the P6 point via two metallic electrodes. Patients can adjust the electrical output to deliver 10-35 milliamps per pulse. Reliefband® (for the indication of CINV) requires a prescription. Acustimulation has been evaluated in CINV and fatigue.
