Cavitation is a process that occurs when a liquid boils or vaporizes, creating bubbles. These bubbles can collapse, causing a shock wave that can damage nearby tissues. The frequency of cavitation is the number of times per second that this process occurs.
Some studies have suggested that lower frequency cavitation is more damaging to tissues than higher frequency cavitation. One theory is that lower frequency cavitation creates larger bubbles, which are more likely to collapse and cause damage. Another theory is that lower frequency cavitation creates more bubbles, which can increase the chance of collision and damage.
There is no definitive answer as to which frequency is best for cavitation. Some studies have suggested that higher frequency cavitation is less damaging to tissues, while other studies have found no difference. Ultimately, the decision of which frequency to use depends on the specific situation and the preferences of the treating physician.
