Table 1 Study set-up and sample size in experimental groups. Intervention abbreviations: ATT = Achilles tendon transection, FCA = free cage activity, PCM = paralysis of calf muscle, SO = steel- orthosis. End point = weeks after ATT.

From: Deprivation of loading during rat Achilles tendon healing affects extracellular matrix composition and structure, and reduces cell density and alignment
