Table 2 Air-structure hysteresis properties of small angles of ulnar-radial deviation ϑ, extension φ > 0 and flexion φ < 0. The properties ΔW for the energy loss, W for the stored energy and D as damping ratio are calculated for the inflation state A: 40 ml, B: 60 ml and C: 80 m for with a deflection of ±6° around 25° for 1 Hz and 5 Hz
