The recommendation is therefore that the stimulation should be applied with a 2500Hz carrier medium frequency sinusoidal alternating current, burst at 50 Hz (10ms ON: 10ms OFF) at a maximum tolerable level.
Ultrasonic frequency is defined as the frequency of an acoustic wave at a frequency above the audible range for humans. This system operates at a base frequency of 40,000 cycles per second or 40 kilohertz (kHz). Due to the design of the âVibra-barâ transducer âSimultaneous Multi-Frequencyâ is produced.
