Tag: High frequency current in physiotherapy

Interferential therapy (IFT) is a popular electrotherapeutic modality for pain management. It is characterized by the interference of 2 medium-frequency currents (ie, 1–10 kHz) , which combine to produce a new medium-frequency current whose amplitude is modulated at low frequency (ie, <1 kHz).

Interferential therapy (IFT) is a commonly used modality in physiotherapy practice for pain relief . Pain relief is believed to be achieved through the production of endogenous opioids like endorphins and enkephalins.

Medium frequency currents are the currents whose frequency falls between the range of 1000 to 10,000 Hz . They are being used therapeutically due to their advantage of greater penetration and with a higher tolerance and comfort over the low frequency current.
