  • GAIT-ER-AIDE (from AI-Medicine)

    Dear Colleagues,

    Last week, I have been browsing by ftp in the ai-medicine database at the US
    National Library of Medicine at NIH in Bethesda, MD, USA (ftp lhc.nlm.nih.gov,
    user ftp, pw your own ident, cd pub/ai-medicine). One item I found particu-
    larly interesting, and I have asked Prof. Bekey for further details; I under-
    stand that he will be at Rancho Los Amigos shortly.

    In 1989, RLA acquired a 3-D video system for movement analysis, so I presume
    that this study might be of interest to some readers of our list.

    With kind regards -- Herman J. Woltring, Eindhoven/NL

    GAIT-ER-AIDE: AN EXPERT SYSTEM FOR ANALYSIS OF GAIT WITH AUTOMATIC
    INTELLIGENT PREPROCESSING OF DATA

    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 sythesizes 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.
