Problems With The Correct Placement Of A Pedometer

The basic function of a pedometer is to count the number of steps you take, although some models also provide information on distance and approximate calories burned. In order for a pedometer to accurately count your steps, you must place it correctly on your body. Many factors can affect how well your pedometer performs.

Pedometer Types

Because pedometers have a mechanism inside that responds to the movement of your body, it can count your steps. The mechanism is typically either a spring lever arm or an accelerometer. The type of sensor mechanism in your pedometer determines how you have to position the device. A pedometer with a spring lever arm has to be level with the ground to work properly. Pedometers with accelerometers can sometimes read your steps even at an angle, such as when it is placed inside a pocket or bag.

Placement

The most basic pedometers with a spring lever arm have to be level with the ground. Attach the device to your waistband or belt so that it is placed halfway between your hip and belly button. Draw an imaginary line from the center of your knee cap up to your waist, and place the pedometer at this point. Make sure it sits level and does not tilt. You can place more advanced pedometers in a pocket or bag depending on the model. Read your owner's manual for placement guidelines.

Factors

A number of factors affect the accuracy of your pedometer, especially a pedometer with a spring lever arm, which cannot accurately sense your steps if it is tilted or turned. If your waistband is loose, this can cause the pedometer to tilt forward. If you have a large abdomen, it may press against the pedometer, pushing it forward. In these cases, you may need to move your pedometer to the side slightly.

Walking Test

Perform a waking test to verify that your pedometer is accurately counting your steps. Place the pedometer on your waistband in line with your knee. Set the counter to zero steps. Walk 100 steps, counting each step yourself without looking at the pedometer. Check the pedometer reading. The United States Department of Agriculture, the USDA, considers your pedometer accurate if it reads between 95 and 105 steps. If not, move the pedometer closer to your hip and try the test again.
