Abstract
The human gait can be analyzed to prevent injuries or gait disorders and make diagnoses or evaluate the progress during the rehabilitation therapies. This work aims to develop a system based on wearable inertial sensors to estimate flexion/extension angles of the lower limbs. Moreover, we have trained a classifier that allows the developed system to differentiate and classify autonomously between four activities of daily living. The proposed classifier is based on a feedforward neural network and has shown an accuracy of 98.33% with users that were not involved in the model’s training.
