Measuring Progress at Home After Surgery Using the Limb Symmetry Index

Document

The Limb Symmetry Index (LSI) provides you with useful information about your leg strength, by using the simple math equation after completing your thigh girth measurements: circumference of the injured leg divided by the circumference of the uninjured leg times 100

For more information on thigh girth measurements and the LSI check out our blog here.

Check out our blog with a video about thigh girth measurements here and a step-by-step video on how to complete the measurement here.
