A high frequency electromagnetic field stimulator for changing nerve threshold comprises at least one electrical stimulator (1), the electrical stimulator (1) comprises at least one positive electrode terminal (12) and at least one negative electrode terminal (13), an insulating spacing of a first gap (b) is arranged between the positive and negative electrode terminals, the positive and negative electrode terminals are a second gap distance (c) away from a to-be-stimulated nerve, a voltage is electrically conducted by the electrical stimulator (1), and the voltage is caused to be less than or equal to 10 V and has a frequency ranging from 200 KHz to 800 KHz. An electromagnetic field is generated by the positive electrode terminal (12) and the negative electrode terminal (13) of the electrical stimulator and is enabled to cover the to-be-stimulated nerve (2) therearound to perform a low-intensity electromagnetic stimulus on the to-be-stimulated nerve, thereby increasing the thresholds of the electromagnetically-stimulated neural regions and achieving the effect that neuropathic pain a patient feels is reduced effectively. |
