INTERVENTIONAL
Conditions
Summary
This protocol outlines a study designed to investigate three different methodologies for inducing gait perturbations. Subjects will be divided into two groups: prosthetic users and able-bodied individuals. Each group will undergo a series of tests where controlled perturbations are applied using up to three methodologies with the number depending on factors such as time and fatigue. These methodologies may include mechanical, visual, or auditory perturbations designed to mimic unexpected obstacles or changes in terrain.
