For convenience, researchers have simulated leg length discrepancy (LLD) by installing an insole or a heel lift in one foot of healthy participants. However, the results of these studies have contradicted the results found in the studies that investigated naturally occurring LLD. The objective of this article was to discuss the methodological considerations of simulated and natural LLD conditions in detail and highlight the inconsistencies in their findings. The studies simulating LLD demonstrate the acute effect of LLD for this reason they should be disparaged for not being physiologic, leading to non-LLD characteristic gait patterns in terms of kinetic and kinematic parameter's. This puts a question mark when it comes to generalizing the results of simulated studies to those that have true LLD.
