Fletcher, Lisa, Park, Hee-Seok and Martin, Bernard J. (1992): Effects of Hand Vibration on Postural Stability. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 765-769.

“The present work was aimed at defining the contribution of vibration-induced perturbation of hand proprioceptive/exteroceptive feedback on standing equilibrium. A vibrating handle, free in space or fixed to a stationary support, was held in the dominant hand while maintaining an erect posture on a force platform, eyes closed. Four arm positions were used. The results show that body sways increase significantly during hand vibration exposure when the handle is fixed. Significant shifts of the center of pressure COP are elicited in every situations. Furthermore, the shifts of the COP are clearly oriented in the direction of the handle when this latter is fixed. It is suggested that the proprioceptive information issued from the hand contributes to the elaboration of a spatial reference and to the control of posture as a function of the environmental context. These results indicate that hand vibration exposure can be considered as a risk factor which may contribute to fall accidents.”
