This study analyzed wheelchair stability during turns. Both three- and four-wheeled racing wheelchairs showed potential instability depending on the specific turning conditions, highlighting the need for further research.

Area of Science:

  • Biomechanics
  • Rehabilitation Engineering
  • Sports Science

Background:

  • Wheelchair racing is crucial for mobility-impaired individuals' rehabilitation and quality of life.
  • Understanding the dynamics of racing wheelchairs is essential for performance and safety.

Purpose of the Study:

  • To conduct simple roll stability analyses on three- and four-wheeled racing wheelchair systems.
  • To evaluate system stability during turning maneuvers.

Main Methods:

  • Performed roll stability analyses on rider/racing wheelchair systems.
  • Focused on turning maneuvers to assess dynamic stability.

Main Results:

  • Three-wheeled systems may exhibit less stability than four-wheeled systems in specific scenarios.

  • Conversely, four-wheeled systems can also be less stable than three-wheeled systems under certain conditions.
  • Stability is highly dependent on the specific circumstances of the turn.

    • Conclusions:

    • Neither three- nor four-wheeled systems are universally more stable; stability is context-dependent.
    • Further research incorporating human factors is necessary to optimize the balance between stability and controllability in wheelchair design.
