  • Invitation to test use the joint coordinate systems

    Hello all,

    In response to my last e-mail about "Summary of responses to Invitation to
    test use JCS", many people informed me that they either did not receive my
    original posting, or missed the original posting. Therefore, I'm sending
    the original posting again. For those who received it before, please
    excuse this repeat posting and simply delete it. For those who expressed
    interest in being involved (in particular, Drs. Pei Lai Cheng, Ruth
    Layanni, Sun G. Chung, Juan V. DurĂ¡), I look forward to hearing from you.

    Original posting follows:

    On behalf of the Standardization and Terminology Committee, International
    Society of Biomechanics (ISB), I would like to invite you to test use the
    Recommendations for Joint Coordinate System (JCS), as proposed earlier by
    various working groups, so that the first hand feedback on these JCSs can
    be received and changes be made accordingly.
    Since November 1993, the ISB Standardization and Terminology Committee has
    begun its journey to propose the standards for defining joint coordinate
    systems of various joints. Nine subcommittees involving a total of 25
    people have been established and, so far, seven proposals have been
    completed. They include ankle, spine, shoulder, elbow, hand and wrist,
    TMJ, and whole body. Some of these proposals have been published in
    previous ISB Newsletters, and some are now available on the ISB Home Page
    ( The detailed information about
    each of these groups is summarized in the following table.
    I would like to express my sincere thanks to all the members who have
    contributed to the establishment of these proposals. While there are a few
    joints whose JCSs are still under development (such as the foot and the
    hip), the proposals for other joints are readily available to be tested.
    The test use process will be:

    1) Each individual (or group) should send an e-mail to Ge Wu at to indicate which joint you will be interested in testing;
    2) Upon request, you will receive a complete proposal via regular mail;
    3) You will follow the definitions and procedures as proposed in the JCS
    proposal in one of your experiments (either on going, or new);
    4) Provide a written report on:
    a) A description of the experiment being conducted;
    b) A description of the procedure for joint angle calculations such as
    marker placement, calibration, and etc. This is to double check if the
    procedure used is exactly the same as the one being proposed;
    c) Comments on how you think about the proposed JCS. What are the
    strengths and weaknesses of the proposal? How you would modify the
    proposal to best satisfy your application?

    Thank you in advance for your support. The standardization of terminology
    in biomechanics of human locomotion is not an easy task. It cannot move
    forward without your help and support.
