Which statement best describes the role of electrical stimulation in tissue healing?

• A. It is only used for acute injuries
• B. It supports wound healing and edema reduction when combined with compression
• C. It replaces the need for debridement
• D. It is contraindicated in all edema

Answer: (B)

The main idea being tested is that electrical stimulation acts as an adjunct to healing, helping both tissue repair and fluid management when used with other treatments. Electrical stimulation can boost healing processes by stimulating cellular activity involved in repair—such as fibroblast activity, collagen production, and epithelialization—and by enhancing local blood flow and oxygen delivery to the wound area. For edema, combining electrical stimulation with compression leverages two mechanisms: the electrical stimulus can promote a muscle pump or lymphatic flow, while compression provides external pressure to help move fluid out of the affected area. Together, they create a more favorable environment for healing and more effective edema reduction. It’s not a standalone replacement for debridement, which removes nonviable tissue essential for healing. And while edema can complicate healing, electrical stimulation is not universally contraindicated for all edema; it is used judiciously as part of a broader wound-care plan when appropriate.
