Using a series of physical and chemical effects such as the mechanical effect, thermal effect, and cavitation effect of ultrasound, a safe dose of ultrasonic energy is applied to the human body to stimulate the body and improve its function, so as to achieve a non-destructive treatment method for the purpose of curing diseases or alleviating symptoms.

According to the preset parameters, the given signal is output, and the patient's limbs are trained simultaneously through the patient's active force or the motor-driven connecting rod mechanism.
