Base trace is the term used to describe the path of what during stance?

• A. Gait line
• B. Swing arc
• C. Base trace
• D. Step line

Answer: (C)

Base trace refers to the path traced by the base of support during stance—the region of the feet in contact with the ground as weight shifts. This shows how the contact area moves on the floor while you stand or step, reflecting stability and how you adjust your feet to maintain balance. It’s different from the swing arc, which is the path of the moving leg through the air, and from the step line or gait line, which relate to foot placement and overall progression. So the base trace specifically captures how the base of support travels on the ground during stance.
