High voltage electrical stimulation is another form of electrical stimulation used by our Toronto physiotherapists. The application of High Voltage is similar to IFC and TENS. However, due to the specific waveform, it is tolerated better and is commonly used in patients who have increased sensitivity to touch. There is substantial research supporting the use of High Voltage to increase blood flow to extremities. Therefore, there is an application for increasing blood flow to a diabetic limb and the use of High Voltage in wound healing.
