Objective diagnosis of equinus during gait prior to and following a tibial nerve block

A quantitative evaluation technique has been developed to assist the clinician in the diagnosis and treatment of ankle equinus deformity. Specifically, the work focuses on accomplishing two major goals: 1) to develop a reliable set of quantitative criteria to assess the degree of dysfunction of the ankle joint during locomotion in patients with equinus deformity; and 2) to determine the effect of various treatment modalities on the ambulatory performance of patients with equinus deformity. A statistically significant difference in two key gait parameters has been demonstrated between healthy subjects and those with equinus deformity.
