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.

Effectiveness of Gait Perturbation Methods in Inducing Stumble or Fall Events
Timeframe: For each gait perturbation method, events are assessed during its application within a single testing session (approximately 30-60 minutes); multiple methods may be tested per session.
Subjective Evaluation of Gait Perturbation Methodologies
Timeframe: Participant feedback is collected immediately after each gait perturbation method within a single testing session (approximately 30-60 minutes); multiple methods may be evaluated per session.
Safety Perception of Gait Perturbation Methodologies
Timeframe: Participant feedback is collected immediately after each gait perturbation method within a single testing session (approximately 30-60 minutes); multiple methods may be evaluated per session.
Unpredictability of Gait Perturbation Methodologies
Timeframe: Participant feedback is collected immediately after each gait perturbation method within a single testing session (approximately 30-60 minutes); multiple methods may be evaluated per session.
Consistency of Gait Perturbation Incidence Rates Over Time
Timeframe: For each gait perturbation method, events are assessed during its application within a single testing session (approximately 30-60 minutes); multiple methods may be tested per session.
