The goal of this study is to assess kinematic changes in the flexion pattern of a digit after resection of a single arm of the FDS tendon (ulnar superficialis slip resection or USSR). Angular joint displacement as a function of a controlled tendon excursion driven by computerized motors was used to quantify the kinematics of the finger. This series of experiments was performed on fresh-frozen cadaver hands, and data was acquired in real time using a National Instruments DAQ card and a PC running LabView software.
