What modality would you use during the proliferative stage of healing?

• A. Cryotherapy
• B. Electrical stimulation
• C. Ultrasound
• D. Hydrotherapy

Answer: (C)

During the proliferative stage, the wound builds new tissue through fibroblast activity, collagen deposition, new blood vessels, and epithelialization. Low-intensity ultrasound supports this regenerative process by providing non-thermal mechanical effects that stimulate cell membranes and boost fibroblast activity and collagen synthesis, along with improving local blood flow. These actions help form granulation tissue and advance epithelialization, which are the goals of this phase. Cryotherapy slows cellular metabolism and vasoconstricts, which can hinder tissue formation in this stage. Hydrotherapy is useful for cleansing and moisture management, but excessive exposure can risk macerating new tissue. Electrical stimulation can aid healing in some cases, but ultrasound most directly promotes the tissue-building processes that characterize the proliferative phase.
