Evaluation of Ankle Joint Movements in Frontal Plane for a Normal Coordinated Gait

As per the records, around 15% of the global population is experiencing some form of disabilities in lower extremity resulting in loss of accessibility to their basic routine movements.The ankle joint complex plays an important role as a weight bearing articulation in the lower extremity and is a key contributor to the power behind human locomotion.While sagittal plane ankle movements are crucial for gait, several studies have proven that inversion-eversion, the frontal plane movements oversee the pressure distribution at the ankle joint to ensure a well-coordinated gait.This paper presents an evaluation of prediction of such ankle joint movements using Electromyogram (EMG), Inertial Measurement Unit (IMU) and Force-Sensitive Resistor (FSR) measurements, which can later be adapted for use in anthropometric active ankle orthosis designs to assist dynamic ankle movements during normal gait in real-time.
