  • Measuring stepping reaction time

    Dear Readers,

    We are planning to measure reaction time in older adults in a stepping task
    and before we set off trying to build the equipment, I thought it might be
    worthwhile asking colleagues whether something might already be available
    for our task. Because this will be field-based research, our plan is to
    have something that is portable and easy to setup and take down. The idea
    would be to have our subject standing on a mat which would close a switch.
    A second 'target' mat would also have a switch in the open position and
    would be positioned a small distance in front of the subject (eg,
    approximately the average step length away). The experimenter would
    initiate the test and at some random interval afterwards, the subject would
    be signalled (by a sound and/or light) to begin. At the same time, a timer
    would start. When the subject lifted his/her foot, the switch in the first
    mat would open and the time from signal to open switch would be displayed on
    one of two display units. The internal timer would continue until the foot
    stepped on the second mat, closing the switch and stopping the timer. This
    time would be displayed on the second display unit. Thus, we would have
    both reaction and movement time. The values could be recorded by the
    experimenter, the system reset and another trial started.

    While this particular setup is not overly complicated, we don't see any
    reason to 'reinvent the wheel'. Our question is: do any of our readers know
    of a device similar to the one I have described? If I receive any
    interesting replies, I will post a summary.

    Thank you.
