Is Electrical Muscle Stimulation Safe?

EMS treatment is generally safe for many, but a few limitations exist for individuals with various conditions. For example, people with extremely sensitive skin may experience skin irritation where the electrodes were placed. People with pacemakers and implantable cardioverter-defibrillator (ICD) are also recommended to use EMS with caution because electrical currents and electromagnetic sources may damage the device if not performed correctly. Other than that, electrical muscle stimulation is safe and effective.
