<p>A low frequency therapeutic device applies low frequency pulses to the body of a patient in order to effect a cure. This device detects whether the output terminal thereof for applying the low frequency pulses to the patient is in contact with the patient to automatically raise the low frequency output voltage from low to high in a gradual manner. Thus, this device reduces the shock to the patient when first applying the low frequency pulses to the patient. </p> |
