Hold your forces: Mechanical stress can help or hinder wound healing depending on time of application

Hold your forces: Mechanical stress can help or hinder wound healing depending on time of application:

A new study demonstrates that mechanical forces affect the growth and remodeling of blood vessels during tissue regeneration and wound healing. The forces diminish or enhance the vascularization process and tissue regeneration depending on when they are applied during the healing process.

The study found that applying mechanical forces to an injury site immediately after healing began disrupted vascular growth into the site and prevented bone healing. However, applying mechanical forces later in the healing process enhanced functional bone regeneration. The study's findings could influence treatment of tissue injuries and recommendations for rehabilitation.
