Human movement comprises complex interactions between the neuromuscular and skeletal systems. In order to design treatments and devices that facilitate the lives of people with movement disabilities, it is essential to understand these interactions. Over time, many researchers have focused on creating models to mathematically represent movements performed by human lower limbs, such as walking, running, and jumping. This type of model provides a noninvasive method to estimate the forces and moments generated in the joints under different conditions, and then make decisions about a specific case study. This article explores the different modeling techniques used for biomechanical analysis of the human lower limb focusing in human walking. Different walking models are developed for a set of parameters and established boundary conditions, common in the lower limb of an average adult, and the results are obtained by mean numerical simulation tools. The results obtained by the different models are compared.
