[An experimental method for measuing flexor pulley's mechanical effects by imitating hand in vivo]

Flexor pulley system has an important mechanical effect on digital flexion function. An experimental method was designed to measure the pulleys' mechanical effects by using hand in vitro to imitate hands in vivo. The pulleys' function was evaluated by pulley incision and pulley preservation, and percentage loss of work was used as an index. The results demonstrate that this experiment is reasonable in design and methodology.
