IFT+TENS+MS+Russian

IFT uses two independent medium-frequency circuits (typically around 4000 Hz) that intersect at the target injury site to create a low-frequency "beat" (1–150 Hz). This design allows the current to pass comfortably through the skin with low resistance and penetrate deeply into muscles, joints, and capsules. It is widely used to relieve deep chronic pain, decrease muscle spasms, and speed up local blood flow and edema (swelling) reduction.
