Insights

This study establishes normative biomechanical gait parameters for children aged 1-7 years, considering age and walking speed. These findings aid in detecting gait abnormalities in young patients.

Area of Science:

  • Orthopaedics
  • Biomechanics
  • Pediatrics

Background:

  • Gait databases are crucial for identifying orthopedic abnormalities.
  • Existing databases lack comprehensive data for children under seven.
  • Child gait is influenced by age and speed, with limited understanding of their interaction.

Purpose of the Study:

  • To establish normative values for biomechanical gait parameters in children.
  • To account for the influence of age, walking speed, and their interaction.
  • To develop a method for detecting gait abnormalities in young children.

Main Methods:

  • Gait analysis of 106 healthy children (1-7 years) at self-selected speeds.
  • Computation of lower limb joint angles and power during gait cycles.
  • Identification of peak biomechanical parameters and their timing using linear regressions.

Main Results:

  • Regressions accurately fitted peak values and timing of biomechanical parameters.
  • Normative reference targets for biomechanical parameters were deduced.
  • A pathological case demonstrated the clinical relevance of the proposed targeting method.

Conclusions:

  • Age-speed regressions provide valuable normative targets for pediatric gait analysis.
  • This approach can assist clinicians in identifying gait abnormalities in children aged 1-7.
  • The developed database enhances diagnostic capabilities in pediatric orthopaedics.
