Which modality is commonly used for wound healing?

• A. Ultrasound
• B. Microcurrent
• C. Massage
• D. Cryotherapy

Answer: (B)

Electrical signaling at a wound site guides the cells that carry out repair. Microcurrent uses very small electrical currents that resemble the body’s own healing currents, so it directly supports those cellular processes. By delivering this near-physiologic stimulation, cells such as fibroblasts and keratinocytes get more energy (ATP) to migrate, proliferate, and synthesize collagen, helping to form new tissue and close the wound. It also tends to improve circulation and can help reduce edema and modulate inflammation, all of which create a more favorable environment for healing. Ultrasound works through mechanical energy and heat to influence tissue repair, which can aid healing but by a different mechanism than the bioelectric signals microcurrent taps into. Massage mainly enhances circulation and tissue mobility and is not targeted to the cellular signaling and energy needs of a healing wound, especially in the early or vulnerable phases. Cryotherapy helps control acute inflammation and pain, but it isn’t typically used as a primary modality to drive the longer-term tissue repair processes.
