Tendon and degeneration or weakening of the tendons, which may eventually lead to tendon rupture. Tendinopathies can be caused by a number of factors relating to the tendon extracellular matrix (ECM), and their classification has been difficult because their symptoms and histopathology often are similar. The first category of tendinopathy is paratenonitis, which refers to inflammation of the paratenon, or paratendinous sheet located between the tendon and its sheath. Tendinosis refers to non-inflammatory injury to the tendon at the cellular level. The degradation is caused by damage to collagen, cells, and the vascular components of the tendon, and is known to
Tendon-driven robot models and tools for simulation control, data acquisition and system investigation. The Anatomically Correct Testbed robotic hand uses tendons and woven finger extensor hoods to capture the biomechanical properties of the human hand. The tendons slide over 3D printed bones matching human bone shapes, reproducing the variable moment arms and some of the tendon network interactions found in the human hand. The tendons are actuated by direct drive (without gearing), allowing them to spool out freely when other tendons oppose them in the skeleton. Tendon-driven robot Tendon-driven robots (TDR) are robots whose limbs mimic biological musculoskeletal systems. They use plastic
