Experimental fittings of sockets for below-knee amputees using computer aided design and manufacturing techniques.
The experiments showed that it is possible to successfully design a socket using a computer based socket model. Variability of results, however indicates the existence of shortcomings. These were identified as inadequacies in the caliper method used to measure the stumps; inability to make the sockets total contact; lack of flexibility of the design process in the Round #1 computer CASD system. It was shown by results of the MERU fittings that an iterative procedure in the hands of an inexperienced person would lead to a degree of success comparable to that achieved by experienced persons using judgement. Also indicated was that experienced prosthetists were able to transfer their skills to the CASD system. This is indicated by the fact that they achieved 5 Class IV results with 8 sockets as compared to 2 Class IV results with 10 sockets achieved by the inexperienced operator.
