The influence of hallux extension on the foot during ambulation.
A review of the literature, focusing on functional anatomy of components of the foot/ ankle complex, provides the rationale for normal hallux extension being a rehabilitation goal when treating patients with foot dysfunction. Hallux extension of 60 to 65 has been found to assist in transforming the foot into the rigid lever necessary for gait, allow the hallux and first metatarsal head to support normal weightbearing loads, and facilitate flexor hallicus longus action during gait.
