Lect. 10 E. Stim for Tissue Healing

Question 1

What are the 3 stages of Wound healing?

Answer 1

1: (acute) -3 days
2: (repair and regeneration) collagen is being laid down
3. (remodelling) straigthen collagen out and make it straighter

Question 2

What type of tissue has been found to produce a measurable current?

Answer 2

injured tissue

-a positive polarity occurs within the wound: this positive polarity stimulates wound healing

Question 3

**What is Galvanotaxis?

Answer 3

A process by which negative ions are attracted to a positive pole and positive ions to a negative pole

Question 4

Alternating current at 80 hz increases what ?

Answer 4

circulation

Question 5

TENS (low and high rate) are effective at increasing what ?

Answer 5

blood flow

Question 6

**Which current Type is best ?

What are some cons?

Answer 6

**Monophasic high voltage direct current: effective for wound healing

cons: it is painful, build up of HCL

Question 7

Polarity: what typeof polarity is most beneficial for wound healing?

Answer 7

alternating polarity: ASSYMETRICAL BIPHASIC

Question 8

What are some Patient instructions for E. Stimulation?

Answer 8

• Contraindications/precautions
• Why

• Let me know if its “COMFORTABLY STRONG”
• Provide someway to patient to contact you
• NEED twitch (do high enough to get a twitchgoing)

Question 9

What is HVPG?

Answer 9

High Voltage pulsed Galvanic

• low amps=for deeper penetration
• high voltage to produce analgesia, muscle contraction, wound healing
