Why is this relevant?:
This research provides information about two commonly addressed lower extremity muscles and their function in the frontal plane. Alterations in frontal plane mechanics of the foot/ankle have been linked to foot/ankle injury, knee pathology, alterations in hip muscle recruitment strategies, and may be associated with lumbosacral dysfunction. Further, these muscles play a role in supination and forefoot rigidity and may be the focus of performance enhancement programming. It is essential for the human professional to have a detailed understanding of the gastrocnemius and tibialis anterior to inform their decision making process when choosing the best exercise, technique or modality for their patient, client or athlete.
