Direct and cross-axes driving-point impedance characteristics of the human hand-arm were measured in the laboratory using a three-axes vibration exciter. The measured data were analyzed to derive the cross-axes components of the impedance and thus the coupling effects in responses of the hand-arm system subject to vibration along different individual axes. The measurements were also performed under simultaneous applications of vibration along all three axes. This preliminary study describes the coupling effects in the biodynamic force measured at the driving-point using the data acquired with three subjects. Results suggest appreciable coupling in forces measured along the Xh and zh-axis, but relatively small coupling was observed in forces along the Xh and Yh-axes.
