The brachial plexus is a complex anatomic structure. No object oriented models of the plexus are described previously. The project goal was to develop an object oriented brachial plexus model. An object oriented model of the plexus called PLEXBASE has been created using Lisp. Interface functions were developed to query the knowledge base. Using logic programming and back-chaining rule-base, decision support rules to diagnose plexus disorders were developed. Development of plexus disorder benchmarks was done to exercise the rule-base. Testing of rules against benchmarks was completed. The sensitivity of each diagnostic rule set (for the corresponding benchmark) was 100%. The brachial plexus model and associated software is comprehensive and accurate for anatomic study and clinical analysis of this important structure.
