Which outcome aligns with tissue extensibility improvement when using ultrasound?

Explanation:
Ultrasound improves tissue extensibility mainly through its heating effect, which raises tissue temperature and makes collagen fibers more pliable, reducing stiffness. This warmth increases the viscoelastic properties of the tissue, allowing it to be stretched further with less resistance. The other options don’t fit because tissue hydration changes, bone turnover, or reduced collagen synthesis are not the mechanisms by which ultrasound enhances soft-tissue extensibility.
