Air-structure test bench for extension φ > 0 in a, flexion φ < 0 in b and ulnar-radial deviation ϑ in c. The Figure shows a single device from different angles, whereas c is a different configuration of a. The air-structure in a shows a fold occurring when deflected φ > 30°. In figure b the estimated wrist flexion radius rflex of 22 mm can be seen
