Three Dimensional Gait Assessment During Walking of Healthy People and Drop Foot Patients

Abstract

The aim of the present study is to clinical gait analysis of normal human and drop foot patients. Gait analysis is the systematic study of <a title="Animal locomotion" href="https://en.wikipedia.org/wiki/Animal_locomotion">animal locomotion</a>, more specifically the study of human motion, using the eye and the brain of observers, augmented by <a title="Instrumentation" href="https://en.wikipedia.org/wiki/Instrumentation">instrumentation</a> for measuring body movements, <a title="Biomechanics" href="https://en.wikipedia.org/wiki/Biomechanics">body mechanics</a>, and the activity of the muscles. Gait analysis is used to assess, plan, and treat individuals with conditions affecting their ability to walk. Foot drop is a deceptively simple name for a potentially complex problem. It can be defined as a significant weakness of ankle and toe dorsiflexion. The foot and ankle dorsiflexors include the tibialis anterior, the extensor hallucis longus (EHL), and the extensor digitorum longus (EDL). These muscles help the body clear the foot during the swing phase and control plantar flexion of the foot at heel strike
