This paper describes the architecture and applications of an expert system designed to identify the specific muscles responsible for a given dysfunctional gait pattern. The system consists of two parts: a data analysis expert system (DA/ES) and a gait pathology expert system (GP/ES). The DA/ES processes raw data on joint angles, foot-floor contact patterns and EMG's from relevant muscles and synthesizes them into a data frame for use by the GP/ES. Various aspects of the intelligent data pre-processing are described in detail, followed by a presentation of the GP/ES, including its structure, knowledge base, rule base, and inference engine. The inference process is clarified by careful analysis of an actual case, a patient with an equinus gait.
