Effects of Hip-Assist Exoskeleton Torque on Gait Parameters

Yonsei University15 enrolled

Overview

This study aims to evaluate the impact of assistive torque from a hip-assist exoskeleton on gait patterns in healthy adults. The investigators will analyze how different torque settings affect spatiotemporal parameters, joint kinematics, muscle activity (EMG), and foot pressure during walking.
