LIMP - Leg Inequality Measurement Pad


LIMP - Leg Inequality Measurement Pad 

Reference: SC2994

Please register and log-in to buy this product


The Leg Inequality Measurement Pad is an easy to use measuring device for the physios, orthotists and podiatrists to determine leg length inequality via the indirect method of measurement.

The LIMP consists of 8 layers of vinyl material tinted for visibility, each layer measuring 3mm thick.

A total of 24mm for the foot-shaped stack. The layers are easily separated by peeling from the toe, and reattached by simply stacking the pieces back together.

The LIMP is durable and will last for years.

The LIMP can also be used to determine optimum heel lift height during orthotic assessements. 

Wipe clean after use.

Very hard wearing - will last for years.

Each device sold Individually.


The Indirect Method for Determining Leg Length Inequality

  1. Have the patient stand with their back to you, and their bare feet 8 inches apart.
  2. Place hands on top of iliac crests to help visualize unleveling. Determine if there is any unleveling of the sacral dimples. Place hands on the Greater Trochanters to determine any unleveling. Determine if there is a spinal curvature, shoulder tilt, or head tilt.
  3. If you have observed unleveling of the iliac crest, greater trochanters, or sacral dimples, have the patient fully suppinate both feet. If the greater trochanters, iliac crests, and sacral dimples are restored to level, then the leg length inequality if determined to be functional. If fully suppinating the feet does not correct the unleveling then the leg length inequality is determined to be structural.
  4. If structural leg deficiency has been determined then place about 2 layers of the Leg Inequality Measurement Pad under the foot of the low iliac crest.
  5. Recheck as in item #3.
  6. If some unleveling persists, continue adding or reducing layers of the Leg Inequality Measurement Pad under foot until you are satisfied with the iliac crest, greater trochanter, and sacral dimple level.
  7. Count the number of layers under foot and multiply by 3mm. The result will be a very close estimate of structural leg deficiency, and the total amount of heel lift, foot lift or combination foot/heel lift required.
  8. If you note severe pelvic asymmetry, then a radiograph of the lumbar spine, pelvis, and femur heads is recommended.
