Many healthcare professionals evaluate and treat leg length inequality (LLI). Anatomical LLI is produced by significant asymmetry in femoral and/or tibial bone length. Functional LLI describes visual, postural, and/or movement asymmetry but without bone length difference. Much clinical literature exists for LLI and its treatment using foot orthotics and/or heel lifts. However, these topics are controversial. The aims of the present case study were to use advanced three-dimensional (3-D) gait analysis technology to quantify postural and gait alterations produced by treatment using foot orthoses and a heel lift in a subject who exhibits clinically obvious LLI.
