Ultrasound and tissue elasticity: what is the described effect?

• A. Increase with ultrasound; stretching during or after
• B. Decrease elasticity
• C. No change
• D. Cause tissue rupture

Answer: (A)

Therapeutic ultrasound mainly increases tissue elasticity by heating the tissue, especially collagen-rich structures. The warmth raises tissue temperature, which makes collagen more viscous and extensible, so the tissue becomes more compliant. That added pliability lets you stretch farther or with less resistance when stretching is performed during or after the ultrasound session. The idea is to use the heating to enhance stretch tolerance and ROM gains, not to weaken tissue or cause rupture.
