Gait analysis by measuring ground reaction forces in children: changes to an adaptive gait pattern between the ages...

Area of Science:

• Pediatrics
• Biomechanics
• Developmental Motor Control

Background:

• Understanding typical gait development in children is crucial for identifying developmental abnormalities.
• Gait analysis provides objective measures of motor function.
• Previous research has not fully detailed the maturational trajectory of specific gait parameters in early childhood.

Purpose of the Study:

• To investigate the maturational profile of gait parameters in typically developing children aged 1 to 5 years.
• To analyze ground reaction forces during independent walking to assess developmental changes.
• To establish normative data for pediatric gait analysis.

Main Methods:

• Fifty-four healthy children aged 1–5 years participated.
• Ground reaction forces were measured using force transducers placed under each foot during walking.
• Key gait parameters including velocity, step length, step frequency, and double support phase were analyzed.

Main Results:

• Gait velocity and step length significantly increased with age.
• Step frequency remained relatively constant across the age range.
• The double support phase decreased significantly, particularly in the first year of walking.
• Adult-like gait patterns, including heel strike and foot rollover, emerged between 2 and 3 years of age.
• No significant left-right asymmetry was observed.

Conclusions:

• Gait parameters mature significantly between ages 1 and 5 years, with distinct changes in velocity, step length, and double support.
• Ground reaction force measurement is a practical and effective method for assessing pediatric gait.
• This approach shows promise for early detection of gait abnormalities in children, including those with neurological conditions.
