Researchers investigated if a dynamic radiographic imaging system affects natural gait. Findings indicate participants slightly altered their stride length and movement patterns when tracked, suggesting a minor impact on natural motion during gait analysis.

Area of Science:

  • Biomechanics
  • Medical Imaging
  • Human Movement Science

Background:

  • Dynamic fluoroscopic imaging and 3D model-image registration offer detailed joint kinematics in small spaces.
  • Mobile radiographic imaging systems aim to capture kinematics during unrestricted activities.
  • The naturalness of movement under dynamic imaging system tracking remains unevaluated.

Purpose of the Study:

  • To determine if a close-up robot tracking system influences natural free-speed gait.
  • To assess the impact of dynamic imaging system tracking on gait parameters.

Main Methods:

  • 14 healthy adults walked in a dynamic radiographic imaging system's workspace.
  • Randomized trials were conducted with and without the system actively tracking knee motion.

3D Kinematic Gait Analysis for Preclinical Studies in Rodents

Published on: August 3, 2019

  • Temporal-spatial and frequency analysis compared kinematic and kinetic parameters.

    • Main Results:

    • Participants showed a small average increase in stride length (0.9 cm).
    • Slight increases in unexplained variation in ankle motion and ground reaction forces were observed.
    • Statistically significant differences suggest participants moved slightly faster when tracked.

    Conclusions:

    • Dynamic radiographic imaging system tracking may subtly influence gait speed and variability.
    • Observed changes in gait parameters were small and potentially clinically insignificant.
    • Further research is needed to fully understand the impact on natural movement during dynamic imaging.
