Physiological and Therapeutic Effects of DL-YII Audio Frequency Therapy Device:

(1) Anti-inflammatory and Anti-swelling Effects

Clinical practice has shown that constant amplitude medium-frequency sine wave current has significant anti-inflammatory and anti-swelling effects. It is effective in treating thrombophlebitis, various subacute and chronic inflammations, as well as swelling from sprains and contusions, and edema caused by systemic lupus erythematosus. It also has notable dispersive and anti-swelling effects. (2) Analgesic and Anti-itch Effects The constant amplitude medium-frequency sine wave current provides good pain relief, treating neuralgia, herpes zoster, and pain from sprains and contusions. A single session offers immediate analgesic effects, though less pronounced than pulsed medium-frequency current, with shorter duration. Audio frequency current significantly relieves itching from post-burn or post-surgical scars.

(3) Softening Scars and Releasing Adhesions Extensive clinical data confirm that persistent treatment with constant amplitude medium-frequency sine wave current effectively promotes the softening and absorption of scar tissue, rapidly contracts abnormally dilated blood vessels in scar tissue, and releases intestinal and scar adhesions. Yang Guoliang reported treating 426 cases of various scars with good efficacy in 57.3%, moderate in 32.8%, and poor or ineffective in 9.9%.

(4) Better efficacy for large scars, poor or ineffective for nodular types. Constant amplitude medium-frequency sine wave current promotes the dispersion and absorption of hematomas and post-injection indurations.
