1. Promoting local blood circulation
Interfering current has a significant effect of promoting local blood circulation. And it lasts for a long time. After 20 minutes of interfering current with a fixed difference frequency of 50Hz, there will be significant changes, and the skin temperature can increase by an average of 2°C. When used for interfering current to act on the cervical and lumbar sympathetic ganglia, it can cause the corresponding limb skin temperature to rise and blood circulation to be strengthened. Therefore, the action of interfering current can accelerate the absorption of exudation, edema and hematoma. Generally, the treatment will disappear significantly after 2 to 3 times, and it can often disappear after 6 to 8 times.
2. Analgesic effect
The analgesic effect of interfering current is also obvious. After 20 minutes of interfering current with a fixed difference frequency of 100Hz and a variable frequency of 0 to 100Hz or 90-100Hz, the skin pain threshold increases significantly, which has a good analgesic effect.
3. Effects on motor nerves and skeletal muscles
Interfering current has a stimulating effect on motor nerves and muscles. The human body can easily tolerate it, and a larger current can be applied, and the muscle contraction reaction caused is also large, so it is superior to low-frequency triangular waves for peripheral nerve damage.
4. Effect on visceral smooth muscle
The interfering current can generate a difference frequency current of 0-100Hz in the deep tissue of the body, which can promote the activity of visceral smooth muscle, increase its tension, improve visceral blood circulation, and adjust the autonomic nerves that control the viscera. Clinically proven to be superior to intermittent electrotherapy in the treatment of gastroptosis, habitual constipation, and postoperative diseases.
5. Regulatory effect on autonomic nerves
When the interfering current acts on the stellate ganglion, it has no significant effect on the blood pressure of normal people, but it can reduce the blood pressure of patients with hypertension, indicating that the interfering current has a certain regulatory effect on the autonomic nerve function.
