The IF-4000 helps control pain and speeds the healing process by delivering small pulses of electrical current to an injury through electrodes that pass current through the skin and stimulate underlying nerves producing a mild, tingling sensation to provide relief from chronic and acute pain. Interferential is used for very localized areas where deep current for pain control or increased circulation is needed.
