prehension
1.Opposition in an important movement of thumb, for thumb opposes other fingers in many types of prehension.
2.For the total root avulsion of brachial plexus, double gracilis transplan tation combined with nerve transfer, a modified Doi?s method, can better restor e the prehension function of the hand.
3.At last, the kinematic analysis of tooth-arrangement multi-fingered hand is accomplished, applying D-H coordinates method to establish kinematic mode of multi-finger hand, and deduce the mutual kinematic relation of coordinates conversion from palm coordinates to finger coordinates of multi-fingered hand, Advanced program software JAVA 3D is employed to simulate multi-fingered prehension by the data acquired from force-close analysis of grasp planning.
