Mechanical Effects of Immobilization on the Achilles’ Tendon

To measure the biomechanical effects of immobilization on the Achilles' tendon.Experimental, controlled study.Physiatry research laboratory.Twenty adult rabbits.One hindlimb immobilized in a cast for 4 weeks (n=10) or 8 weeks (n=10). The contralateral legs (n=20) served as controls.Cross-sectional Achilles' tendon area, mode of failure, mean failure load, and tendon stiffness.The Achilles' tendon cross-sectional area did not change.
