Pulsed emission EQultrasound hand probes (Concave Silver Hand Probe, Flat Silver Hand Probe, Ultra-Focused Hand Probe and Convex Hand Probe) generate intense mechanical non-thermal effects within biological tissues.
This treatment modality is indicated for pathologies still in the acute phase or in general when heat is an undesirable element. In fact pauses in the ultrasound wave emission allow the dissipation of heat by blood circulation.
The mechanical non-thermal effects produced by EQultrasound are:
- stable cavitation
- acoustical streaming
- mechanical vibration (micro-massage)
Cavitation is the term used to describe the influence of an ultrasonic wave on the formation, growth and oscillation of micro-bubbles inside interstitial fluids (which are the fluids that bathe and surround cells). The oscillation of micro-bubbles in response to the ultrasound wave, without an increase in the bubbles’ overall size, is called stable cavitation.
Periodic radial oscillations of these micro-bubbles inside interstitial fluids (stable cavitation), create complex streaming patterns within the liquid in the vicinity of the oscillating bubble surface.
Acoustical streaming is the movement of interstitial fluids along cell membranes.
Microstreaming consists of circular currents inside interstitial fluids surrounding the cavitational bubbles, which make cells and intracellular organelles twist and rotate generating a form of micro-massage.
Furthermore the pulsed emission modality creates a very strong mechanical vibration on treated tissues, resulting also in a form of micro-massage, which actively supports the drainage of edemas, hematomas and excess fluids build-up in general.
