1. The electrode is often placed at a special point, that is, the trigger point, the acupuncture point and the movement point.
Because of the low skin resistance at these special points, there is a high density input to the central nervous system.
These points are the effective parts for placing the electrodes.
2. Frequency selection The patient feels that the symptoms can be relieved.
Chronic pain should be 14 ~ 60Hz; postoperative pain should be 50 ~ 150Hz; herpes pain should be 15 ~ 180Hz; peripheral nerve injury after 30 ~ 120Hz.
It is generally advisable for the patient to choose the frequency that he or she considers appropriate. Most patients are suitable for a stimulation frequency of 100 Hz and a width of 0.1 to 0.3 ms.
3. Current intensity: It is appropriate to cause obvious tremor without pain. Generally 15 ~ 30mA, depending on the disease tolerance.
4. Treatment time: treatment of burning neuralgia for 2 to 3 minutes. It usually takes 20 minutes and can last up to 1 hour or several hours.
