Abstract
Anthropometric data has been collected for the development of a biomechanical model of the hand. This model will be used to determine the load distribution on the surface of the hand and the reaction moments required at each joint in response to contact with another object. This model will be applied to the design of hand tools and work stations, so that they may be used with the least possible mechanical stresses. The model is developed on a kinematic basis, using a system composed of joints and segments. These segments do not correspond to the physiological skeletal system, but provides a mathematical basis for hand movement and a frame to hold the skin and other soft tissues in place. This study collected data on segment length between joint centers, using radiographic techniques and the method of Peuleaux. This data has been correlated with actual bone lengths and total digit length. Anthropometric data on the depth of the soft tissues of the hand will also be required to facilitate the kinematics of hand grip posture and other hand-object contact. A knowledge of the material properties of soft tissue will be necessary to develop the mechanics required to determine the load distribution on the hand.
