Abstract
Using selective electrical stimulation, we report the distributions of medial and lateral gastrocnemius subtendon representations within the healthy and ruptured Achilles tendon. In the majority of our sample, lateral gastrocnemius subtendon was found in the most anterior region adjacent to medial gastrocnemius both in the healthy and ruptured, nonsurgically treated tendon. The tendon internal displacement pattern does not seem to differ, but displacement amplitude and nonuniformity differed between healthy and ruptured tendons 1 yr after rupture.
