The object of our studies is to automatically measure the residual hand of an amputee and to systematically produce a prosthetic hand. It is also our object to produce a micro-computer-based measuring system which can quickly process reductions, magnifications, changes, additions and corrections, and to produce a manufacturing system which can effectively utilize numerically controlled machines. We have measured the hands of about 30 normal persons and those of 6 amputees in a manner which enables us to model a prosthetic hand comparable to a normal hand. The outcome of those measurements has been to produce a prosthetic hand which is useful in the rehabilitation field. The prosthetic hand has been designed to have adaptive functions and to be a functional hand, with various grip models, including that of "shaking hands," for example. Using a CAD system, we have designed a cosmetic cover and inner model in which MP, PIP and DIP joints move separately. As results, (1) The functional cosmetic hand was designed by CAD system. (2) Up to now, it has been impossible to store all the numerical data of the residual hand. (3) Commonly, functional hands were designed from a simple, standardized length measurements. (4) Individually matched manufacture has become possible, because the shape of the residual hand is reversed in the micro-computer. (5) Data processing such as magnifications, reductions and eliminations, which required a great deal of time previously, has become much easier. (6) In addition to the utilization of the system in rehabilitation, it is possible to use various transformations to obtain an estimation of the shape of the hand in different positions (for example, cosmetic aids for hands of patients with rheumatism.)
