Increased blood flow has been shown in many studies (going back as far as the 1940’s to the present day) from the application of RF:

Kumaran (2017) looked at deep blood flow using doplar and found significant increases with Tecarpuls use. Below are the doplar images:

 Before treatment

After Treatment

As can be seen there is a significant increase in deep blood flow. Below is the chart indicating the change:

As can be seen RF, both high and low, increased deep blood flow compared to placebo. Although the control group increased this was not significant and within the margin for error. Interestingly pulsed shortwave group blood flow decreased (this could be related to the faster recovery of tissue temperature from this treatment).
