Functional hallux limitus Functional hallux limitus is generally defined as a deformity of the first metatarsophalangeal joint that acts to restrict the range of movement of dorsiflexion during the propulsive phase of gait. (Chapman C.,1997) Different authors refine this basic definition further, some adding a further qualification that it is defined by a reduction of the range of dorsiflexion to less than 65 degrees. (Camasta C A.,1996). If the range is reduced to less than 5 degrees then the t
