Are Pedometers Accurate?
Accurate pedometers are those with step-count errors less than 10%, high or low. That is, your pedometer should not count more than 110 steps, or fewer than 90 steps, if you walk 100 steps. Research shows that pedometers tend to count steps more accurately at speeds greater than 4.5 kms per hour (kmph) than at slower speeds. Inaccuracy can occur due to the insensitivity of pedometers to detect steps when people shuffle or drag their feet at slow speeds. Detectable vertical movement of the hips is necessary for pedometers to work well.
