Cats adopt a pacing gait on treadmills, unlike overground locomotion. This gait helps maintain stability and avoid foot collisions, especially during sudden stops.

Area of Science:

  • Comparative biomechanics
  • Animal locomotion analysis

Background:

  • Treadmill locomotion differs from overground locomotion, but underlying mechanisms remain unclear.
  • A common difference is the adoption of a pacing gait (ipsilateral legs move together) instead of a diagonal gait.

Purpose of the Study:

  • To quantify gait patterns in cats during overground and treadmill locomotion.
  • To investigate the mechanical factors influencing gait differences between overground and treadmill environments.

Main Methods:

  • Conventional video analysis was used to record and quantify cat gait.
  • Cats' locomotion was analyzed at various speeds both overground and on a motorized treadmill.

Main Results:

  • Cats exhibited a pacing gait more frequently at the front of the treadmill enclosure.

  • This pacing gait was linked to an extended stride length and a higher support duty factor.
  • The extended stride was hypothesized to anticipate sudden treadmill stops and prevent ipsilateral foot collisions.

    • Conclusions:

    • Cats adjust their gait on treadmills to enhance stability and manage stride length.
    • The pacing gait may be a strategy to improve the duty factor and avoid self-collision in the confined treadmill space.
