PHTY1023 HEAT AND COLD THERAPY
EXAM (ACTUAL EXAM) WITH CORRECT
ACTUAL QUESTIONS AND CORRECTLY
WELL DEFINED ANSWERS LATEST
ALREADY GRADED A+ 2025 – 2026
Pain and cryotherapy - ANSWERS-Proposed to decrease pain via several
mechanisms
-decreased neural conduction velocity
-↓release of pain irritants (↓inflm. response)
-Action on "pain-gate" mechanism
-Release of endorphins and encephalins
2 ways tissue injury may occur with cryotherapy. - ANSWERS-Excessive cold
causing damage to normal tissue.
Normal local cooling causing damage due to a predisposing pathological
condition.
, Excessive local cold on normal tissue. - ANSWERS-Ice burn
-Mild: erythema and skin tenderness a few hours after treatment
-Severe: fatty necrosis. Bruising and more tenderness. Can last up to 3 weeks.
Peripheral nerve damage.
Extreme cold can cause cell death.
Slower extreme cooling can lead to ECF freezing and drawing water from cells
→ frost bite.
Reduced peripheral vascular supply. - ANSWERS-Peripheral vascular disease,
vasospasm, blockages or pressure caused by posture.
Restricted blood supply ↑ risk of tissue damge in crytherapy.
Rate of perfusion ↓ so oxygenation of cells can be affected.
Vasospasm - ANSWERS-Cold sensitivity (Raynaud's phenomenon). Excessive
vasoconstriction, triggered by cold, occurs in digital arteries.
Cryoglobiaemia - ANSWERS-Abnormal protein in blood forms precipitate at
lower temperatures causing ischeamia.
Associated with CT disorders such as rheumatoid arthritis.
Heating vascular effects. - ANSWERS--Heat applied to skin stimulates
cutaneous thermoreceptors which results in vasodilation.
-Has minimal effect on deeper skeletal muscle blood flow
