On a Model of the Upper Extremity
The function of the upper extremity is an interesting and important issue. The function of the hand and the wrist can not easily be separated from the rest of the extremity. There is a mechanical and a mental coupling. However, it is not apriori clear how to distinguish the two effects. The whole system is an underdetermined mechanical system and it is difficult to make measurements both in vivo and in vitro. These complications make it difficult to evaluate a mechanical model.
