Abstract: The utilization of sensors towards the study of internal and external work at the distal lower extremity during movement is presented. Inertial Measurement Units (IMUs) and Electromyography (EMG) sensors are paired together to calculate the neuromuscular effort and torque at the ankle and are compared with plantar pressure and torque measurements using the pressure mat. Subsequently image tracking data is also to inform machine learning models that predict real-world distance movement from video recorded movement. Finally, a mobile application is developed allowing users to see a simulation of their movements, among other information.
