Which factors influence the choice between using TENS versus HVPC for edema management?

• A. HVPC specifically targets edema reduction and wound healing; edema-dominant issues favor HVPC, while pain-dominant issues may favor TENS or IFC as appropriate
• B. TENS is always better for edema
• C. HVPC only used for pain control
• D. IFC never used for edema

Answer: (A)

The main idea is choosing the therapy based on what is driving the problem: edema reduction or pain relief. High-voltage pulsed current (HVPC) has properties that help move fluid and stimulate lymphatic drainage, which can reduce edema and also support wound healing. Because of that, when swelling is the dominant issue, HVPC is the more appropriate choice.

If pain is the main concern, therapies like TENS or interference current (IFC) are focused on analgesia, often through gate-control mechanisms or endogenous opioid pathways, and may be chosen to address pain even if some edema is present. TENS and IFC are not primarily aimed at reducing edema, which is why edema-dominant cases tend to favor HVPC, while pain-dominant cases may favor TENS or IFC. The other statements don’t fit because they either imply TENS is always best for edema, claim HVPC is only for pain control, or say IFC is never used for edema.
