Abstract

A combined qualitative–quantitative approach towards the analysis of the ground reaction forces is suggested so as to detect deficiencies and predict hazards in human locomotion. The population studied is a group of patients who have undergone partial or full arthrodesis of the ankle–subtalar joint complex. The various ways in which the effects of ankle fusion are reflected on the force characteristics are discussed. The non-uniformity of reflection suggests an elaborate compensatory mechanism which is also being considered. As a conclusion it is suggested that surgical corrections such as immobilization of joints may be hazardous to the skeletal elements unless adequate compensatory walking habits are developed. The reduced flexibility of the system has to be compensated either by involving other joints, such as the knee, in the force attenuation process or by provision of flexible footware.
