BPA Unit 8: Alternate Electrotherapeutic Applications

Question 1

What is Iontophoresis?

Answer 1

A technique that uses electrical uses electrical current to introduce medicines or ions transcutaneously into target tissues
- Iontophoresis implies the delivery of a medicinal ion for therapeutic benefit

Question 2

What are the indications of Iontophoresis?

Answer 2

• Neuralgia
• Edema
• ischemic skin ulcers
• Hyperhidrosis
• Plantar warts
• Gouty arthritis
• Calcific tnedonitis
• Scar tissue
• To reduce inflammation

Question 3

With the Physiology of Iontophoresis, what is electromigration?

Answer 3

Like charges repel and opposites attract

Question 4

With the Physiology of Iontophoresis, what is electroporation?

Answer 4

An increase in the porosity of the superficial skin in response to E-Stim and may facilitate movement of ions into tissues

Question 5

With the Physiology of Iontophoresis, what is electroosmosis?

Answer 5

A Mechanism by which ions are moved into the tissues

Question 6

Which medicines is the MOST appropriate when using iontophoresis to treat inflammation?

Answer 6

The most common of these is dexamethasone
sodium phosphate that is anti-inflammatory

Question 7

What is dosage based on Iontophoresis?

Answer 7

Based on the current amplitude of the direct current and the duration of the current

Dosage equation:
- Dosage (mA/min) = Current (mA) x Duration (min)

20 to 80 mA/min is the average dose. Time will depend on patient sensitivity

Question 8

What are the Contraindicatios for Iontophoresis?

Answer 8

They should not be placed over…
- The tunk or heart region with pacemakers or ICDs
- The Pelvic, abdmoninal, lumbar, or hip region with pregnant women
- Carotid bodies
- Phrenic nerve or urinary bladder stimulators
- Areas of known PVD
- Areas of active osteomyelitis
- Areas of hemorrage

Question 9

What does a EMG Biofeedback do?

Answer 9

Provides info about the muscle activity that the patient and clinician can use to increase or decrease the future activity of a treated muscle

Question 10

What are the indications of a Biofeedback?

Answer 10

EMG biofeedback can be used to facilitate or inhibit muscle contraction

Question 11

How can a biofeedback be used with Post-surgery ACL reconstruction?

Answer 11

• First days after surgery: High Sensitivity (gain of 1 uV) the machine will detect minimum muscle contraction
• Few weeks after surgery: Low sensitivity (gain of 500 uV); the patient must produce stronger contradictions to be sensed by the device
