TENS

Question 1

What are the 3 models used for pain control in TENS?

Answer 1

Spinal gate

Central biasing

Opiate control

Question 2

What is central biasing?

Answer 2

Afferent input activates negative loop through midbrain

Question 3

What are the contraindications to TENS?

Answer 3

Pregnancy

Malignancy

Implanted electrical device

Cardiac arrhythmia

Over carotid sinus

Areas of catheters

Areas of thrombus

Areas of active hemorrhage

Active TB

Over thoracic region with cardiac dysfunction

Over spinal column

Question 4

How does TENS help?

Answer 4

Pain control

Increase in functional movement tolerance

Muscle re education

Muscle strengthening

Reduction of inflammation

Reduction of muscle spasms

Reduction of trigger points

Relaxation of muscle

Question 5

How does TENS help with muscle activation and re education?

Answer 5

Regain ability to voluntarily contract

Stimulates muscle to prevent disuse atrophy during immobilization

Question 6

How does TENS accelerate tissue healing?

Answer 6

Increasing blood flow, tissue oxygenation, and migration of tissue healing cells

Decreases associated wound pain

Creates reciprocal muscle pumping to mitigate edema

Question 7

Why would you choose IFC versus TENS?

Answer 7

Bigger surface area must use 4 electrodes

Going deeper (more powerful)
