Reference Values of Flexion and Supination in the Elbow Joint of a Cohort without Shoulder Pathologies

Figure 1

(a) Schematic design of the custom dynamometer with the vertical ergonomic handle bar, disc 1, disc 2, torque sensor, and base plate (from left to right). (b) The tracks allow subject-dependent adaptation of the height of the dynamometer. The dynamometer is connected to the computer. (c) Details of the two ergonomic handle bars. The vertical handle bar is intended for the supination strength whereas the horizontal one is intended for the flexion strength measurement.
