This study details a triangular force platform for postural analysis, measuring force components for clinical research. Simplified regulations allow for easy integration into computer systems for enhanced stability feedback.

Area of Science:

  • Biomechanics
  • Medical instrumentation
  • Human movement analysis

Background:

  • Postural analysis is crucial for understanding human stability and diagnosing neurological or musculoskeletal disorders.
  • Accurate measurement of force distribution and center of pressure is essential for effective postural assessment.
  • Existing systems may lack simplicity or direct feedback mechanisms for clinical application.

Purpose of the Study:

  • To analyze a triangular force platform integrated with a computer system for postural analysis.
  • To develop a simplified system for clinical research applications in postural stability.
  • To enable visual feedback for postural stabilization.

Main Methods:

  • A triangular force platform with steel rings at the corners was employed.

  • Tensions in the rings, proportional to force moments, were amplified using tensotransducers, preamplifiers, and low-frequency filters.
  • An analog decoder processed signals to determine weight and anterior-posterior/lateral force components.

    • Main Results:

    • The system successfully registered and amplified force-related signals.
    • An electrical signal proportional to weight and force components was generated.
    • The system's simplified design facilitates its use in clinical research settings.

    Conclusions:

    • The analyzed force platform system provides a viable method for measuring postural forces.
    • The generated signals can be utilized for visual feedback to improve postural stabilization.
    • The simplified design makes the system suitable for clinical research and potentially therapeutic applications.
