In vivo characterization of Achilles subtendon function and morphology within the tendon cross section and along the free tendon

Kathryn S. Strand, Todd J. Hullfish, Josh R. Baxter

This study develops a method to quantify subtendon sliding in the Achilles tendon using ultrasound and electrical stimulation, finding differential displacement patterns based on stimulated muscle.

Gastrocnemius muscle remodeling explains functional deficits three months following Achilles tendon rupture

Todd J. Hullfish, Kathryn M. O’Connor, Josh R. Baxter

This study shows that muscle-tendon structural changes after Achilles tendon rupture correlate with functional deficits, emphasizing the need to preserve muscle structure for recovery.
