The design of a prosthesis should take into account a number of factors, some of which are in conflict. Information is needed, not only on the requirements for each aspect, but also on the interaction between them.
A prosthesis for dysmelic children is being built, embodying a deliberate compromise between as many of the factors as possible, in order to study first the specification and design problems and then the function and acceptability of the result. The problems of movement and control will be discussed in detail, including the choice of control sites, the movements patterns needed, and the means by which these are linked. Initial experience with the device will be reported.
