Thermotherapy & Cryotherapy

Question 1

What are the 4 Physiological Effects of Thermotherapy?

Answer 1

1) Pain Modulation
2) Vasodilation
3) Decrease in resting muscle tone
4) Reduction in tissue viscosity

Question 2

What is Pain Modulation?

Answer 2

Gate-theory pain relief at the level of the spinal cord

Question 3

What does Vasodilation do involving pain?

Answer 3

Increased blood flow leads to increased supply of oxygen.
Systemic Effect: Reflex Vasodilation with one area being heated, increased blood flow to other areas of the body

Question 4

What does a decrease in resting muscle tone mean?

Answer 4

Decrease in gamma bias
Possible part of pain gating mechanism?

Question 5

What happens as a result of reduced tissue viscosity?

Answer 5

Decrease resistance to flow
Increased tissue extensibility

Question 6

What are the 3 indications for thermotherapy?

Answer 6

1) Temporary Pain Relief
2) Promotion of Tissue Healing
3) Promotion of Tissue Mobility
