a
Data were analyzed with repeated mixed-effects models with group and time as main factors followed by the Šidák multiple comparisons test. Creep and total gap elongation were analyzed with an independent Student t test. Values for circumference, ROM, and heel-rise height are the limb symmetry index (percentage of the noninjured side). ATRS, Achilles tendon Total Rupture Score; ROM, range of motion.
b
Values are expressed as mean ± SD.
