  • Diabetics & leg fatigue

    Dear Colleagues,

    I wish to induce muscle fatigue in the foot and leg in a population of
    healthy Diabetics inorder to assess any effect on their walking gait. To
    induce fatigue in a healthy athletic population I have successfully used a
    modified shuttle run fitness test.

    The concern I have is that when measuring the subject's perception of
    fatigue via a revised Borg scale (RPE), there can be confusion to whether
    the subject truly perceives fatigue, or lacks the motivation to continue
    the rather boring and repetitive task.

    My understanding of exercising a Diabetic person is that their blood sugar
    levels will reduce and this may induce central fatigue and lead to an
    alteration in their mood. If this is so, then potentially they may
    withdraw from the fatigue inducing protocol due to lack of motivation to
    continue the task rather than perceiving fatigue.

    Does anyone have knowledge of a fatigue inducing protocol for feet and
    Has anyone experience of exercise testing with Diabetics?

    I would value your comments, experiences and any words of wisdom.
    Naturally, I will post a summary to the group.

    Yours faithfully,
