Subtalar Everters, Fibularis Longus & Brevis | Structure, Function & Exercises

The video tutorial covers the anatomy and function of the muscles in the lateral lower leg compartment, focusing on the fibularis longus and brevis. It explains their origins, insertions, innervation, and blood supply. The tutorial also discusses the role of these muscles in subtalar eversion and plantar flexion. Additionally, it provides exercises to strengthen these muscles, particularly in neurological conditions where eversion strength is compromised. The extensor digitorum longus is also highlighted for its role in eversion.
