Researchers have found that an upstream promoter of two extracellular matrix proteins increases healing and strength capabilities in the tendons of rats.

Tendon injuries in older people

Previous research has found that, like with many other injuries, tendon injuries have an age-related component. The tendons of the biceps and rotator cuffs are more commonly injured in older people than in younger people [1], and older people heal slower after forearm injuries and have less range of motion in the fingers for a longer time [2].
