Which systems are affected by superficial cryotherapy?

• A. Digestive and Endocrine
• B. Circulatory, Neuromuscular, Metabolic
• C. Skeletal and Integumentary
• D. Respiratory and Immune

Answer: (B)

Superficial cryotherapy mainly affects systems that respond directly to surface cooling: the circulatory system, the neuromuscular system, and tissue metabolism. The cold triggers vasoconstriction, reducing blood flow to the area and helping control edema and inflammation—this is a circulatory effect. It also slows nerve conduction velocity and can dampen motor unit activity and spindle sensitivity, which changes neuromuscular function and can lessen pain and reflex activity. Additionally, the cooling lowers tissue metabolic rate, decreasing cellular metabolism and oxygen demand—a metabolic effect. Because the cooling is surface‑level, it doesn’t directly engage digestive or endocrine processes, and while the integumentary system (skin) is obviously involved, the question targets these broader systemic responses.
