Normative force data of knee and hip joint muscles of young adults in gait

Comprehensive documentation of lower extremity muscle forces and patterns in gait is still lacking in literature. Such information may provide valuable baseline data for applications in rehabilitation, exercise, and robotics. Therefore, the purpose of this study was to determine muscle forces and patterns of knee and hip joints during the entire gait cycle of young college students. The results from this study provided detailed and normative peak muscle force data of the knee and hip joints in six sub-phases during a gait cycle. These results also demonstrated the coordination between the uni- and bi-articular muscles and agonist and antagonist muscles throughout the gait cycle.
