Yes, there are usually considerable differences. Physiotherapy ultrasound is usually of 1MHz (and sometimes 3MHz) frequency and of maximum power of around 10 Watts. Quite often it is used at a fraction of this maximum power, usually anything between 1 Watt and 5 Watts. This is because physiotherapy ultrasound is meant to stimulate and it is also used in a very small area, hence the low powers. Sometimes, low frequency ultrasound (300kHz) is used in physiotherapy but at very, very low powers (0.5-1 Watt). Some machines used in beauty, for cellulite reduction or other purposes, can also be of…
Cavitation for cellulite: how does it work?
It is widely accepted today that high-power, low-frequency ultrasound treatment represents one of the few effective methods of cellulite reduction and, to a limited extent, subcutaneous fat reduction too. It often provides good results on its own, if the right equipment is used with the right protocols, and even better results when combined with high-power, deep-tissue radio frequency. But what is ultrasound cavitation and how does it work?
