Question 1

Types

Answer 1

Twin-peak
Monophasic
Pulse current

Question 2

Clinical Applications

Answer 2

• Muscle contraction
• Pain modulation
• • Tissue healing
• Edema control

Question 3

Tissue Healing (Becker Theorized)

Answer 3

• Endogenous current present in human tissues after trauma and diseases
• Endogenous current may be important in soft tissue repair

Question 4

When endogenous bioelectric system fails

Answer 4

• exogenous electrical current is delivered to the wound, enhancing wound healing

Question 5

Dosage for Wound Management

Answer 5

• Voltage: 150 - 250 V
• Pulse frequency: Arbitrary, between 0.1 and 200 pps
• Mode: pulse or continuous
• Electrode polarity: Reversal of polarity
• Treatment duration: often 60 minutes
• Treatment frequency: daily or 5-7 times / week

Question 6

Electrode Placement

Answer 6

• Both electrodes are positioned over healthy tissues adjacent to the wound margins

Question 7

Considerations for Application

Answer 7

• Aseptic technique to prevent cross-contamination between patients
• Topical wound care products composed of hypertonic salt solutions or metal ions should be avoided for several days prior to applying HVPC
