  • Wireless Accelerometers for Wrist Impact Falling Studies

    Dear BIOMCH-L subscribers:

    I am assisting our College of Kinesiology and undergraduate engineering
    students on the development of an impact falling setup for assessing impact
    forces & accelerations on the wrist. This area is outside my research focus
    and I would appreciate any input.

    We are specifically seeking advice regarding wireless accelerometers used
    for measuring impact accelerations during falling (forward or backwards),
    with a specific emphasis on the wrist. We would like to integrate
    accelerometer readings with force plate readings and kinematic motion
    analyses (Vicon), using the DAQ system supported by VICON (or with a
    stand-along DAQ / LabView).

    We will be measuring accelerations in children and adults during falling,
    using a foam padding to prevent fractures. The experienced g's when falling
    on a foam surface will be less than a realistic setting, hence we will also
    simulate realistic falls using experimental testing w/ dummy models.
    Different g ranges for the accelerometers will be required for these two
    applications, and we would appreciate advice on this issue also.

    Our specific questions pertain to:

    1. Do you know of any wireless accelerometers which integrate with VICON /
    DAQ systems with relative 'ease'?

    2. What 'g' ranges did you use for falling studies (dummy-based and

    3. Are there any recommended commercially available foam surfaces for
    falling studies?

    4. What advice would you provide regarding possible pitfalls / troublesome

    Any and all advice would be greatly appreciated.
