• To assess the system's effectiveness on a commercial Force Platform.

Main Methods:

• A system was designed to generate a circular CoP path in the horizontal plane.
• Parameters like travel speed, radius, and vertical force are selectable.
• The system was applied to a commercial Force Platform for validation.

Main Results:

• The system successfully generated accurate circular CoP paths for testing.
• It provided a precise reference for both static and dynamic Force Platform measurements.
• Feasibility and effectiveness were confirmed on a commercial device.

Conclusions:

• The developed system offers an accurate and flexible method for Force Platform calibration.
• It enables reliable verification of platform performance against manufacturer specifications.
• The system enhances the precision of clinical biomechanical data acquisition.
