Summary
This study establishes typical gait parameters for children using wireless inertial sensors. Age influences gait, with older children exhibiting distinct support and swing phases, offering a baseline for atypical gait analysis.
Area of Science:
- Pediatrics
- Biomechanics
- Gait Analysis
Background:
- Objective gait assessment in children is increasingly important.
- Establishing baseline parameters for typical gait is crucial for comparison.
Purpose of the Study:
- To investigate typical gait parameters in healthy preschool and school-aged children.
- To use wireless inertial sensors as a reference for atypical gait analysis.
- To compare gait parameters between younger and older children.
Main Methods:
- Evaluated gait parameters of 161 children using a G-Walk BTS G-SENSOR smart analyzer.
- Children walked barefoot at self-selected speeds on a walkway.
- Gait data was collected during a back-and-forth walking trial.
Main Results:
- Age significantly impacts spatiotemporal gait parameters, with support and swing phases changing with age.
- Older children demonstrated shorter double support and longer single support times.
- Pelvic tilt symmetry increased with age, and girls showed more symmetrical pelvic obliquity than boys.
Conclusions:
- The study provides reference parameters for typical children's gait.
- These findings can aid in identifying atypical gait patterns in cases of trauma or disability.
