Conditions
Brief summary
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.
Interventions
A wearable robot that provides assistive torque (Flexion/Extension) to the hip joint during walking.
